Work in agriculture carries the risk of trauma as a result of mechanization (farm equipment and machinery), location of cultivated areas, and multi-functionality. In agriculture, the hands were the most affected parts of the body which sustained injury. Successful suturing of a finger initially disqualified from replantation is rare. The case is presented of a 55-year-old patient who had a non-work-related finger amputation. In a surgical centre not belonging to the reference ones in plastic surgery in Poland, a doctor with six months of surgical experience performed the replantation without vascular reconstruction (the amputated distal part of the finger served as a biological dressing). Despite the lack of vascular reconstruction and unfavourable prognosis, the amputated fragment of the finger maintained a partial blood supply. Subsequent flap surgery in the plastic surgery department, and rehabilitation of the patient due to finger contracture, led to functional recovery of the finger.

Introduction: Ankylosing spondylitis is chronic progressive disease, which decrease functions of musculoskeletal system including chest area. Those changes influences respiratory mechanics, worsen conditions of proper ventilation of lungs., Objectives: Rating of functional and respiratory parameters and dependence between them at patients with ankylosing spondylitis., Materials & Methods: The study included 45 patients with diagnosed ankylosing spondylitis. Chest and upper limbs mobility, resting spinal curvature alignment were assessed, and respiratory parameters were measured in a plethysmographic chamber JAGGER MasterScreen Body., Results: Ankylosing spondylitis patients had lower respiratory parameters especially sReff, and FRC. Restriction of chest and upper limbs mobility was also demonstrated. Forward head extension was observed based on the occipital wall test. Correlations between functional parameters and correlations between functional and respiratory parameters were shown, in particular MIP, MEP, sReff, Rtot, TLC, ERV., Conclusions: The study confirmed a decrease in functional and respiratory parameters in the examined patients with ankylosing spondylitis compared to the applicable standards. A significant relationship was found between functional parameters in the upper body and respiratory parameters, which worsen with increasing thoracic dysfunction. The obtained results indicate the directions of therapy that should be taken into account to improve respiratory parameters and reduce respiratory dysfunction in these patients. Chest-focused physiotherapy appears to be an important element in improving function in patients with ankylosing spondylitis., (© 2024. The Author(s).)

Ischemic stroke is one of the leading causes of death and disability. As the currently used neurorehabilitation methods present several limitations, the ongoing research focuses on the use of non-invasive brain stimulation (NIBS) techniques such as transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS). NIBS methods were demonstrated to modulate neural excitability and improve motor and cognitive functioning in neurodegenerative diseases. However, their mechanisms of action are not fully elucidated, and the clinical outcomes are often unpredictable. This review explores the molecular processes underlying the effects of TMS and tDCS in stroke rehabilitation, including oxidative stress reduction, cell death, stimulation of neurogenesis, and neuroprotective phenotypes of glial cells. A highlight is put on the newly emerging therapeutic targets, such as ferroptotic and pyroptotic pathways. In addition, the issue of interindividual variability is discussed, and the role of neuroimaging techniques is investigated to get closer to personalized medicine. Furthermore, translational challenges of NIBS techniques are analyzed, and limitations of current clinical trials are investigated. The paper concludes with suggestions for further neurorehabilitation stroke treatment, putting the focus on combination and personalized therapies, as well as novel protocols of brain stimulation techniques.

Wilson's disease (WD) is inherited in an autosomal recessive manner and is caused by pathogenic variants of the ATP7B gene, which are responsible for impaired copper transport in the cell, inhibition of copper binding to apoceruloplasmin, and biliary excretion. This leads to the accumulation of copper in the tissues. Copper accumulation in the CNS leads to the neurological and psychiatric symptoms of WD. Abnormalities of copper metabolism in WD are associated with impaired iron metabolism. Both of these elements are redox active and may contribute to neuropathology. It has long been assumed that among parenchymal cells, astrocytes have the greatest impact on copper and iron homeostasis in the brain. Capillary endothelial cells are separated from the neuropil by astrocyte terminal legs, putting astrocytes in an ideal position to regulate the transport of iron and copper to other brain cells and protect them if metals breach the blood-brain barrier. Astrocytes are responsible for, among other things, maintaining extracellular ion homeostasis, modulating synaptic transmission and plasticity, obtaining metabolites, and protecting the brain against oxidative stress and toxins. However, excess copper and/or iron causes an increase in the number of astrocytes and their morphological changes observed in neuropathological studies, as well as a loss of the copper/iron storage function leading to macromolecule peroxidation and neuronal loss through apoptosis, autophagy, or cuproptosis/ferroptosis. The molecular mechanisms explaining the possible role of glia in copper- and iron-induced neurodegeneration in WD are largely understood from studies of neuropathology in Parkinson's disease and Alzheimer's disease. Understanding the mechanisms of glial involvement in neuroprotection/neurotoxicity is important for explaining the pathomechanisms of neuronal death in WD and, in the future, perhaps for developing more effective diagnostic/treatment methods.

Purpose: To identify correlations between demographic, health-related, environmental factors and the employment status of power wheelchair (PWC) users. Method: We retrospectively analysed semi-structured interviews with 128 participants, their assistants or family members, and the participant's provided medical records. Participants were adult PWC users who applied for grants in purchasing a new PWC for gaining or keeping employment between 2019-2021 in Mazovian Province, Poland. Results: Forty-six PWC users (35.9%) were employed while applying for the financial support programme. Fischer's Exact Test of Independence identified positive correlations between employment and education level (p < 0.001), residing in an urban area (p = 0.02), being employed before starting PWC use (p < 0.001), having vocational rehabilitation (p < 0.001), and living in a relationship (p = 0.002). There were no associations between employment status and sex, age at study entry, age at disability onset, living alone or with others, duration of PWC use, or full or part-time PWC use. Our findings indicate that PWC users are at risk of non-employment and financial hardship. This research may support policies for PWC provision that would support gainful employment. The results show that access to quality education, vocational rehabilitation, and perhaps the physical/emotional support from others in close relationships matter. These aspects should be considered in educational policies, transportation, and physical environmental accessibility for PWC users, supporting their gainful employment.

Regaining greater independence in performing daily activities constitutes a priority for people with tetraplegia following spinal cord injury (SCI). The highest expectations are connected with the improvement of hand function. Therefore, it is so important for the clinician to identify reliable and commonly applicable prognostic factors for functional improvement. The aim of this study was to conduct an analysis to assess the impact of initial functional factors on the clinical improvement in patients during early neurological rehabilitation (ENR). This study assessed 38 patients with complete SCI aged 17-78 who underwent ENR in 2012-2022. The analysis included the motor score from the AIS (MS), the Barthel Index (BI) and the SCIM scale values at the beginning of the ENR program and after its completion. During ENR, patients achieved a statistically significant improvement in MS, BI and SCIM. The initial MS and the level of neurological injury constituted the predictors of functional improvement during ENR. Significant statistical relationships were observed primarily in the correlations between the initial MS and BI, and the increase in the analyzed functional scales of SCI patients. Higher initial MS may increase the chances of a greater and faster functional improvement during ENR.

Background: Mood disorders, especially depression, and emotional difficulties such as anxiety are very common problems among patients with spinal cord injuries (SCIs). The lack of physical training may deteriorate their mental state, which, in turn, has a significant impact on their improvement in functioning. The aim of the present study was to examine the influence of innovative rehabilitation approaches involving robotic-assisted gait therapy (RAGT) on the depression and anxiety symptoms in patients with SCI., Methods: A total of 110 participants with subacute SCIs were enrolled in this single-center, single-blinded, single-arm, prospective study; patients were divided into experimental (robotic-assisted gait therapy (RAGT)) and control (conventional gait therapy with dynamic parapodium (DPT)) groups. They received five training sessions per week over 7 weeks. At the beginning and end of therapy, the severity of depression was assessed via the Depression Assessment Questionnaire (KPD), and that of anxiety symptoms was assessed via the State-Trait Anxiety Inventory (STAI X-1)., Results: SCI patients in both groups experienced significantly lower levels of anxiety- and depression-related symptoms after completing the seven-week rehabilitation program (KPD: Z = 6.35, p < 0.001, r = 0.43; STAI X-1: Z = -6.20, p < 0.001, r = 0.42). In the RAGT group, post-rehabilitation measurements also indicated an improvement in psychological functioning (i.e., decreases in depression and anxiety and an increase in self-regulation (SR)). Significant results were noted for each variable (STAI X-1: Z = -4.93; KPD: Z = -5.26; SR: Z = -3.21). In the control group, there were also decreases in the effects on depression and state anxiety and an increase in self-regulation ability (STAI X-1: Z = -4.01; KPD: Z = -3.65; SR: Z = -2.83). The rehabilitation modality did not appear to have a statistically significant relationship with the magnitude of improvement in the Depression Assessment Questionnaire (KPD) (including self-regulation) and State-Trait Anxiety Inventory (STAI) scores. However, there were some significant differences when comparing the groups by the extent and depth of the injury and type of paralysis. Moreover, the study did not find any significant relationships between improvements in physical aspects and changes in psychological factors., Conclusions: Subjects in the robotic-assisted gait therapy (RAGD) and dynamic parapodium training (DPT) groups experienced decreases in anxiety and depression after a 7-week rehabilitation program. However, the rehabilitation modality (DPT vs. RAGT) did not differentiate between the patients with spinal cord injuries in terms of the magnitude of this change. Our results suggest that individuals with severe neurological conditions and complete spinal cord injuries (AIS A, according to the Abbreviated Injury Scale classification) may experience greater benefits in terms of changes in the psychological parameters after rehabilitation with RAGT.

The improvement of walking ability is a primary goal for spinal cord injury (SCI) patients. Robotic-assisted gait training (RAGT) is an innovative method for its improvement. This study evaluates the influence of RAGT vs. dynamic parapodium training (DPT) in improving gait motor functions in SCI patients. In this single-centre, single-blinded study, we enrolled 105 (39 and 64 with complete and incomplete SCI, respectively) patients. The investigated subjects received gait training with RAGT (experimental S1-group) and DPT (control S0-group), with six training sessions per week over seven weeks. The American Spinal Cord Injury Association Impairment Scale Motor Score (MS), Spinal Cord Independence Measure, version-III (SCIM-III), Walking Index for Spinal Cord Injury, version-II (WISCI-II), and Barthel Index (BI) were assessed in each patient before and after sessions. Patients with incomplete SCI assigned to the S1 rehabilitation group achieved more significant improvement in MS [2.58 (SE 1.21, p < 0.05)] and WISCI-II [3.07 (SE 1.02, p < 0.01])] scores in comparison with patients assigned to the S0 group. Despite the described improvement in the MS motor score, no progression between grades of AIS (A to B to C to D) was observed. A nonsignificant improvement between the groups for SCIM-III and BI was found. RAGT significantly improved gait functional parameters in SCI patients in comparison with conventional gait training with DPT. RAGT is a valid treatment option in SCI patients in the subacute phase. DPT should not be recommended for patients with incomplete SCI (AIS-C); in those patients, RAGT rehabilitation programs should be taken into consideration.

Wilson's disease (WD) is a rare autosomal recessive (AR) disorder resulting from mutations in the ATP7B gene, which is responsible for the encryption of transmembrane copper transporting ATPase. The symptomatic presentation of the disease is estimated to be about 1 in 30,000. The impairment of ATP7B function results in a copper overload in hepatocytes, which further leads to liver pathology. This copper overload also occurs in other organs, most particularly in the brain. This could then cause the occurrence of neurological and psychiatric disorders. Symptoms differ substantially and most often occur between the ages of 5 and 35 years. Early symptoms are commonly hepatic, neurological, or psychiatric. While disease presentation is most often asymptomatic, it could also range as far as to include fulminant hepatic failure, ataxia, and cognitive disorders. Various treatments are available for Wilson's disease, including chelation therapy and zinc salts, which can reverse copper overload through different mechanisms. In select cases, liver transplantation is recommended. New medications, such as tetrathiomolybdate salts, are currently being investigated in clinical trials. With prompt diagnosis and treatment, prognosis is favorable; however, diagnosing patients before the onset of severe symptoms is a significant concern. Early screening for WD could help in diagnosing patients earlier and improving treatment outcomes.

Polymyositis (PM) and dermatomyositis (DM) are rare idiopathic inflammatory myopathies (IIM). Myocardial involvement in patients with IIM is an unfavorable prognostic factor and one of the most common cause of mortality in this group of patients. The purpose of this review is to present current knowledge on cardiovascular manifestations observed in IIM. Data published in English until December 2021 were selected. Clinical symptoms suggesting cardiac involvement are non-specific and require a differential diagnosis in accordance with cardiological guidelines. Troponin I is specific to cardiac injury and should be preferred to other markers to evaluate the myocardium in IIM. Abnormalities in electrocardiography are common in IIM, especially non-specific changes of the ST-T segment. In standard echocardiography left ventricular diastolic dysfunction is reported frequently. New diagnostic technologies can reveal clinically silent myocardial abnormalities. However, the prognostic value of subclinical impairment of myocardial function require further studies., Competing Interests: The authors declare no conflict of interests., (Copyright: © 2023 Narodowy Instytut Geriatrii, Reumatologii i Rehabilitacji w Warszawie.)

Metals-especially iron, copper and manganese-are important elements of brain functions and development. Metal-dysregulation homeostasis is associated with brain-structure damage to the motor, cognitive and emotional systems, and leads to neurodegenerative processes. There is more and more evidence that specialized cognitive and motor exercises can enhance brain function and attenuate neurodegeneration in mechanisms, such as improving neuroplasticity by altering the synaptic structure and function in many brain regions. Psychological and physical methods of rehabilitation are now becoming increasingly important, as pharmacological treatments for movement, cognitive and emotional symptoms are limited. The present study describes physical and cognitive rehabilitation methods of patients associated with metal-induced neurotoxicity such as Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, Huntington's disease and Wilson's disease. In our review, we describe physical (e.g., virtual-reality environments, robotic-assists training) and psychological (cognitive training, cognitive stimulation, neuropsychological rehabilitation and cognitive-behavioral and mindfulness-based therapies) methods, significantly improving the quality of life and independence of patients associated with storage diseases. Storage diseases are a diverse group of hereditary metabolic defects characterized by the abnormal cumulation of storage material in cells. This topic is being addressed due to the fact that rehabilitation plays a vital role in the treatment of neurodegenerative diseases. Unfortunately so far there are no specific guidelines concerning physiotherapy in neurodegenerative disorders, especially in regards to duration of exercise, type of exercise and intensity, as well as frequency of exercise. This is in part due to the variety of symptoms of these diseases and the various levels of disease progression. This further proves the need for more research to be carried out on the role of exercise in neurodegenerative disorder treatment.

Background: Occipital pressure sores (OPS) are complications of the use of cervical collars. Prophylaxis of OPS in patients after cervical spinal surgery (CCS) appears to be neglected., Material and Methods: Cochrane Central, EMBASE, PubMed, SCOPUS, and Web of Science databases were searched for studies on OPS after CCS., Results: We present the case of a patient with rheumatic arthritis who was secured with a hard collar after revision CCS and was not seen by a health professional due to the COVID-19 outbreak. The result was an OPS leading to deep tissue infection. The patient required a prolonged hospital stay and long-term antibiotic therapy. We found a lack of literature on OPS prevention in patients after CCS., Conclusions: Patients with rheumatoid arthritis using collars after CCS are at risk of OPS. Protocols of prevention of OPS should be reviewed with respect to challenges resulting from epidemiological restrictions and accessibility of telemedical technologies., Competing Interests: The authors declare no conflict of interests., (Copyright: © 2022 Narodowy Instytut Geriatrii, Reumatologii i Rehabilitacji w Warszawie.)

Background: Central sensitization is an amplification of neuronal signaling within the central nervous system. The Central Sensitization Inventory was introduced in 2012. A Polish version of the CSI (CSI-Pol) was developed in 2019, but it was not psychometrically validated. The aim of this study was to validate the CSI-Pol in a sample of Polish-speaking patients with chronic spinal pain and compare them with a group of healthy control subjects., Methods: The CSI-Pol was administered to 151 patients with chronic spinal pain recruited from two centers. It was re-administered 7 days later. The psychometric properties were then evaluated, including test-retest reliability, construct validity, factor structure and internal consistency. We correlated the CSI-Pol with functional scales, depression and social support scales and compared CSI-Pol scores in the clinical subjects with 30 healthy control subjects recruited from medical staff and their families., Results: The CSI-Pol demonstrated excellent internal consistency (Cronbach's α =0,933) and test-retest reliability (Intraclass Correlation Coefficients - ICC =0.96), as well as significant positive associations with other patient-reported scales, including the Neck Disability Index (r = 0.593), Revised Oswestry Low Back Pain Disability Questionnaire (r = 0.422), and other measures of functional and depressive states. An exploratory factor analysis resulted in a 4-factor model. CSI-Pol scores in the clinical sample (35.27 ± 17.25) were significantly higher than the control sample (23.3 ± 8.9)., Conclusion: The results of this study suggest that the CSI-Pol may be a useful clinical tool for assessing central sensitization related symptoms and guiding appropriate treatment in Polish-speaking patients with spinal pain., (© 2021.

Objective: To examine relationships between age and spinal cord injury (SCI) and cause of SCI and how this depends on economic development., Design: Cross-sectional survey., Setting: Community, 22 countries representing all stages of economic development., Participants: A total of 12,591 adults with SCI (N=12,591)., Interventions: Not applicable., Main Outcome Measures: Interactions between age at injury and gross domestic product per capita based on purchasing power parity (GDP PPP) quartiles calculated with the application of logistic regression with the Maximum Likelihood estimator. Independence between SCI cause and age was assessed with the Wald test., Results: In persons with traumatic SCI, younger age was associated with a higher likelihood of injury in motor vehicle collisions, whereas older individuals had a greater chance of SCI due to falls. Associations between increased likelihood of high-energy traumatic SCI and younger age, low-energy traumatic SCI with older age, nontraumatic SCI with older age in persons injured in adulthood, and a higher prevalence of incomplete SCI lesions in individuals injured at an older age were revealed. Higher GDP PPP influenced positively the likelihood of low-energy SCI in older individuals and was negatively associated with the chance of sustaining SCI in motor vehicle collisions and the likelihood of having nontraumatic SCI at an older age., Conclusions: SCI in older age is predominantly because of falls and nontraumatic injuries. Higher country income is associated with an increased proportion of SCI sustained later in life because of low-energy trauma involving cervical injury and a lower chance of being because of motor vehicle collisions. An increased prevalence of nontraumatic SCI in older individuals associated with lower country income may reflect a higher exposure to socially preventable conditions and lower access to or efficacy of health care. Future studies on etiology of SCI should make the distinction between low and high falls and overcome underrepresentation of older persons., (Copyright © 2021 The American Congress of Rehabilitation Medicine.

Copper, manganese, and iron are vital elements required for the appropriate development and the general preservation of good health. Additionally, these essential metals play key roles in ensuring proper brain development and function. They also play vital roles in the central nervous system as significant cofactors for several enzymes, including the antioxidant enzyme superoxide dismutase (SOD) and other enzymes that take part in the creation and breakdown of neurotransmitters in the brain. An imbalance in the levels of these metals weakens the structural, regulatory, and catalytic roles of different enzymes, proteins, receptors, and transporters and is known to provoke the development of various neurological conditions through different mechanisms, such as via induction of oxidative stress, increased α-synuclein aggregation and fibril formation, and stimulation of microglial cells, thus resulting in inflammation and reduced production of metalloproteins. In the present review, the authors focus on neurological disorders with psychiatric signs associated with copper, iron, and manganese excess and the diagnosis and potential treatment of such disorders. In our review, we described diseases related to these metals, such as aceruloplasminaemia, neuroferritinopathy, pantothenate kinase-associated neurodegeneration (PKAN) and other very rare classical NBIA forms, manganism, attention-deficit/hyperactivity disorder (ADHD), ephedrone encephalopathy, HMNDYT1-SLC30A10 deficiency (HMNDYT1), HMNDYT2-SLC39A14 deficiency, CDG2N-SLC39A8 deficiency, hepatic encephalopathy, prion disease and "prion-like disease", amyotrophic lateral sclerosis, Huntington's disease, Friedreich's ataxia, and depression.

Introduction: Spinal cord injury (SCI), which disrupts motor, sensory and autonomic functions, causes significant changes in the functioning of an individual. It is believed that most of the conditions secondary to SCI, i.e. osteoporosis, spasticity or cardiopulmonary diseases, are associated with immobility. The aim of the study is to assess the adherence to prescriptions of therapeutic exercises (APTE) in patients with SCI after acute phases of rehabilitation., Material and Methods: The criterionfor APTE recognition was the performance at least twice a week for a minimum of 30 minutes of active exercises with resistance, and exercises maintaining the range of movement of the joints The research tools were own questionnaire and the WHOQOL-BREF scale., Results: 46 subjects (63.9%) met the APTE criteria. The most frequent place for performing the exercises was the subject's home with 43 subjects (93.5%) with APTE performed the exercises in their homes. 17 subjects (36.9%) with APTE performed exercises during stays at various rehabilitation centres. The main cause for the lack of APTE was the limited availability of facilities considered necessary by the respondents to adhere to the instructions. In statistical analysis, the level of neurological injury correlated with meeting the APTE criteria. It was discovered that a subjective assessment of the exercise dose correlated with the place where the exercises were performed, but did not correlate with meeting the APTE criteria., Conclusions: The basic place for performing exercises (as instructed in hospital) was the subject's home. Limited access to reimbursed environmental therapy resulted in an increased cost of exercises supervised by commercially-employed physiotherapists. The current gaps in the system of supervision and counselling of subjects post-SCI necessitate changes in the Polish health care system.

Context/objective: Autonomic dysreflexia (AD) is an emergency condition typical for individuals with spinal cord injury (SCI). Adequate health professionals' knowledge of AD is important for the effective and safe rehabilitation of persons with SCI. The purpose of the study is to assess the knowledge of AD in undergraduate and postgraduate physiotherapists. The data gained will be useful for better addressing of AD in clinical practice., Design: An observational study., Setting: Rehabilitation College in Warsaw, Medical University of Warsaw, Poland., Participants: 52 undergraduate and 68 postgraduate physiotherapists., Intervention: AD knowledge testing., Outcome Measures: A test assessing knowledge of causality and consequences of AD created at the Medical University of Warsaw., Results: No significant differences in test scores between under- and postgraduates were found (P = 0.09). Higher scores were noted in physiotherapy masters as compared to bachelors (P = 0.01), in participants who have an in-patient practice (P = 0.04), a practice longer than 5 years (P = 0.02) and those who see patients with SCI more frequently (P = 0.01). A self-assessed knowledge of AD was admitted as poor or none by 96.2% of undergraduates and 86.8% of postgraduates., Conclusion: In the studied population the knowledge of causality and consequences of AD presented by undergraduate and postgraduate physiotherapists was low. Lower test scores were associated with a lower level of professional education achieved, having an outpatient practice only and having fewer patients with spinal cord injury. Efforts should be made to improve undergraduate and postgraduate education on AD of physiotherapists.

Objectives: The aim of this study is to draw the attention of patients, doctors and therapists to the importance of temporomandibular joint (TMJ) problems in rheumatoid arthritis (RA)., Material and Methods: The research was conducted at the National Institute of Geriatrics Rheumatology and Rehabilitation in Warsaw. The study involved 60 subjects. The test group consists of 30 patients with diagnosed RA. The control group ( n = 30) consisted of healthy participants of similar age. The study analyzed the occurrence of problems in TMJ joints, acoustic phenomena and the level of pain. Masseter muscle development, range of abduction motion and pain during palpation of soft tissues were assessed on the basis of the joint pain map of Prof. Mariano Rocabado., Results: In the RA group, more than half (56.7%) had problems with the TMJ, 70% of them had masseter hypertrophy and clicks in the TMJ, and 46.7% had tinnitus (in the control group: 10%, 30%, and 30%, respectively). Patients also had a limited range of abduction movement in the TMJ (38.0 ±6.1 mm). Analysis of the pain map of Prof. Mariano Rocabado in RA patients indicates a significantly greater number of pain structures. In the control group no pain was observed in structures such as the posterosuperior synovial and bilaminar zone, posterior ligament, or retrodiscal area., Conclusions: Temporomandibular joint problems in RA patients were more serious than in the control group and these differences were statistically significant for most tests. The awareness of the problem with the TMJ in RA patients is very low; participants of our study were 100% unaware that the function of the TMJ could be improved. Additionally, there are no guidelines for the treatment and rehabilitation of these joints., Competing Interests: The authors declare no conflict of interest., (Copyright: © 2021 Narodowy Instytut Geriatrii, Reumatologii i Rehabilitacji w Warszawie.)

Copper is one of the most abundant basic transition metals in the human body. It takes part in oxygen metabolism, collagen synthesis, and skin pigmentation, maintaining the integrity of blood vessels, as well as in iron homeostasis, antioxidant defense, and neurotransmitter synthesis. It may also be involved in cell signaling and may participate in modulation of membrane receptor-ligand interactions, control of kinase and related phosphatase functions, as well as many cellular pathways. Its role is also important in controlling gene expression in the nucleus. In the nervous system in particular, copper is involved in myelination, and by modulating synaptic activity as well as excitotoxic cell death and signaling cascades induced by neurotrophic factors, copper is important for various neuronal functions. Current data suggest that both excess copper levels and copper deficiency can be harmful, and careful homeostatic control is important. This knowledge opens up an important new area for potential therapeutic interventions based on copper supplementation or removal in neurodegenerative diseases including Wilson's disease (WD), Menkes disease (MD), Alzheimer's disease (AD), Parkinson's disease (PD), and others. However, much remains to be discovered, in particular, how to regulate copper homeostasis to prevent neurodegeneration, when to chelate copper, and when to supplement it.

Polyunsaturated fatty acids ( ω -3 acids, PUFAs) are essential components of cell membranes in all mammals. A multifactorial beneficial influence of ω -3 fatty acids on the health of humans and other mammals has been observed for many years. Therefore, ω -3 fatty acids and their function in the prophylaxis and treatment of various pathologies have been subjected to numerous studies. Regarding the documented therapeutic influence of ω -3 fatty acids on the nervous and immune systems, the aim of this paper is to present the current state of knowledge and the critical assessment of the role of ω -3 fatty acids in the prophylaxis and treatment of spinal cord injury (SCI) in rodent models. The prophylactic properties (pre-SCI) include the stabilization of neuron cell membranes, the reduction of the expression of inflammatory cytokines (IL-1 β , TNF- α , IL-6, and KC/GRO/CINC), the improvement of local blood flow, reduced eicosanoid production, activation of protective intracellular transcription pathways (dependent on RXR, PPAR- α , Akt, and CREB), and increased concentration of lipids, glycogen, and oligosaccharides by neurons. On the other hand, the therapeutic properties (post-SCI) include the increased production of endogenous antioxidants such as carnosine and homocarnosine, the maintenance of elevated GSH concentrations at the site of injury, reduced concentrations of oxidative stress marker (MDA), autophagy improvement (via increasing the expression of LC3-II), and p38 MAPK expression reduction in the superficial dorsal horns (limiting the sensation of neuropathic pain). Paradoxically, despite the well-documented protective activity of ω -3 acids in rodents with SCI, the research does not offer an answer to the principal question of the optimal dose and treatment duration. Therefore, it is worth emphasizing the role of multicenter rodent studies with the implementation of standards which initially may even be based on arbitrary criteria. Additionally, basing on available research data, the authors of this paper make a careful attempt at referring some of the conclusions to the human population., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2020 Piotr Wojdasiewicz et al.)

Background: The use of adaptive equipment (AE) is the basic indication for patients with spinal cord injury (SCI). Inappropriate decisions concerning the use of AE imply treatment results, patient confidence, and patient and state costs. The present study is the first analysis of the causes of non-compliance conducted in Europe with the provision of AE in SCI patients using Wielandt and Strong's classification., Aim: The aim of this study is to analyze of the causes of non-compliance in the process of providing AE to SCI patients., Design: Retrospective observational study., Setting: "STOCER" Masovian Rehabilitation Centre, Konstancin-Jeziorna, Poland., Population: Seventy-two patients with traumatic SCI 10 months after the completion of the acute and post-acute phases of inpatient rehabilitation., Methods: Wielandt and Strong's classification was used to determine the causes of non-compliance with AE provisions and the present authors' questionnaire with the World Health Organisation Quality of Life (WHOQOL-BREF) were used to identify the risk factors of non-compliance with AE provisions., Results: Non-compliance with prescribed AE provisions was reported in 34 (49.3%) of 69 study participants. Non-compliance was due to medical-related factors in 44.1%, client-related factors in 20.6%, equipment-related factors in 11.8%, and unspecific factors in 17.8% of cases. Non-compliance with AE provisions correlated with complete neurological deficit, preserved ability to walk (in case of wheelchairs), the presence of bedsores (in cases of lower extremity devices), low financial status, and lost ability to walk (in cases of AE for standing and walking). The highest percentage of non-compliance was noted for the provision of knee-ankle-foot orthosis (50%)., Conclusions: The most common causes of non-compliance with AE provisions include health status improvement in the patient and high cost of the device., Clinical Rehabilitation Impact: These results can be helpful for more effective treatment planning and the avoidance of unnecessary reimbursement costs covered by the state and users.

Background: Multiprofessional teamwork in physical and rehabilitation medicine (PRM) allows achieving patient-centered goals in accordance with the assumptions of the bio-psycho-social model of functioning. Team composition and methods of collaboration depend of the specificity of goals to be achieved, as well local contextual factors. International comparative studies on rehabilitation teamwork are lacking, despite data on how teams differ between countries are crucial for the process of harmonization of PRM practice across Europe., Aim: To compare models of collaboration within rehabilitation teams in Central Europe., Design: A cross-sectional explorative study., Setting: The data were collected in Bulgaria, Croatia, Czech Republic, Hungary, Poland, Romania, Slovakia between February and June 2018., Population: PRM physicians., Methods: An anonymous questionnaire inquiring of rehabilitation teamwork details was spread through national PRM societies, and other organizations associating PRM physicians. An ordered logit regression was applied to analyze the results., Results: Responses were obtained from 455 respondents. Significant differences between the studied countries in the composition of rehabilitation teams and frequencies of team meetings were detected. In the analyzed population of PRM physicians, we found positive associations between the chance of participation in team meetings and working in a hospital, the amount of time devoted to PRM practice, and older age. The chance for patients and caregivers to participate in rehabilitation team meetings was correlated with PRM physician's hospital practice, activity as a PRM teacher, older age and devoting more time to PRM practice. Country specificities of rehabilitation team content were analyzed with regards to local economic, legal, and historical backgrounds, and availability of human resources. Underrepresentation of key professionals (e.g. occupational therapists, orthotists/prosthetists), inadequate distribution of professionals in healthcare and as well as outdated educational systems in some countries may affect the efficacy of the comprehensive care in rehabilitation., Conclusions: Central European countries differ in rehabilitation teamwork with regard to the contribution of professionals, meeting frequencies, and participation of patients and caregivers. Well-designed studies on teamwork models delineating ways to improve teamwork efficacy are in demand., Clinical Rehabilitation Impact: Between-country diversity of rehabilitation team content should be considered while planning activities aimed at European harmonization of PRM practice.

Osteoporosis is a civilization disease which is still challenging for contemporary medicine in terms of treatment and prophylaxis. It results from excessive activation of the osteoclastic cell line and immune cells like macrophages and lymphocytes. Cell-to-cell inflammatory information transfer occurs via factors including cytokines which form a complex network of cell humoral correlation, called cytokine network. Recently conducted studies revealed the participation of CX3CL1 chemokine in the pathogenesis of osteoporosis. CX3CL1 and its receptor CX3CR1 present unique properties among over 50 described chemokines. Apart from its chemotactic activity, CX3CL1 is the only chemokine which may function as an adhesion molecule which facilitates easier penetration of immune system cells through the vascular endothelium to the area of inflammation. The present study, based on world literature review, sums and describes convincing evidences of a significant role of the CX3CL1/CX3CR1 axis in processes leading to bone mineral density (BMD) reduction. The CX3CL1/CX3CR1 axis plays a principal role in osteoclast maturation and binding them with immune cells to the surface of the bone tissue. It promotes the development of inflammation and production of many inflammatory cytokines near the bone surface (i.e., TNF- α , IL-1 β , and IL-6). High concentrations of CX3CL1 in serum are directly proportional to increased concentrations of bone turnover and inflammatory factors in human blood serum (TRACP-5b, NTx, IL-1 β , and IL-6). Regarding the fact that acting against the CX3CL1/CX3CR1 axis is a potential target of immune treatment in osteoporosis, the number of available papers tackling the topic is certainly insufficient. Therefore, it seems justified to continue research which would precisely determine its role in the metabolism of the bone tissue as one of the most promising targets in osteoporosis therapy., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2019 Piotr Wojdasiewicz et al.)

Head and neck injuries are common and can be associated with cervical vessel injury. In some cases, the cor-rect diagnosis of artery dissection can be a real challenge given the nonspecific signs. We present the case of a spinal cord-injured patient with neurological sequelae and delayed posterior circu-la-tion stroke caused by bilateral vertebral artery dissection. The signs of cerebellar and occipital lobe ischemia were masked by manifestations of spinal cord injury. The patient was unconscious and in a serious condition, but, despite no proper stroke treatment, only residual dysarthria and upper limb ataxia were seen after reha-bilitation. Any clinical suspicion based on the combination of head or neck trauma with atypical or evolving neuro-logical symptoms should be verified for the possibility of a vertebral artery dissection.

Objectives:: To present a synopsis of evidence on the efficacy of rehabilitation after cervical disk surgery performed for neck pain and radiculopathy., Data Sources:: The databases of Medline, EMBASE, and Cochrane Central were searched for studies reporting effects of rehabilitation interventions in patients undergoing surgery due to cervical disk disease with pain and radicular syndrome, published before 31 August 2018., Review Methods:: Project was registered with PROSPERO database (number CRD42018085937). Randomized controlled trials that evaluated the efficacy of rehabilitation interventions versus other, sham, or no treatment were selected. The primary outcomes were disability and pain. Secondary outcomes were other measures assessing biological, psychological or social effect of rehabilitation. Two reviewers independently screened studies for eligibility, assessed risk of bias and extracted data. Evaluation of evidence was performed with the GRADE system., Results:: Five papers were included in the review. The eligible studies were heterogeneous in intervention and outcome reporting. There are low- to very-low-quality evidence that some interventions (use of cervical collars after non-plated anterior cervical diskectomy an fusion, structured physiotherapy, and interactive patients' education) provide some benefit within functioning, pain, and selected psychological variables in patients undergoing cervical disk surgery. Controlled trials addressing comprehensive interdisciplinary rehabilitation, multidisciplinary pain management, occupational therapy, psychotherapy, social and vocational interventions were not identified., Conclusion:: There is insufficient evidence with few trials of low quality to allow any conclusion to be drawn about the effectiveness, harms, and general ineffectiveness of rehabilitation for people who have had cervical disk surgery for pain or radiculopathy.

Objectives: Inflammatory processes in rheumatic diseases spread via various types of immune system cells and tissues with the aid of inflammatory cytokines and growth factors and the participation of vascular endothelium. Research is still conducted to determine the role of individual factors in the pathophysiology of rheumatic diseases. The task is complicated because the multiplane network of cytokines is characterized by complex correlations manifesting as positive and negative feedback, which impedes the definitive interpretation of the role of specific cytokines. Therefore, it seems justified to perform a comparative analysis of the expression of at least several molecules in one study, which may help reveal their role in the pathogenesis of rheumatic diseases and have prognostic value., Material and Methods: The aim of the study involves the assessment and comparative analysis of the concentrations of interleukin 35 (IL-35), tumour necrosis factor α (TNF-α), B-cell-activating factor (BAFF), and vascular endothelial growth factor (VEGF) in peripheral blood serum in patients with rheumatoid arthritis (RA) ( n = 43), systemic lupus erythematosus (SLE) ( n = 28), antiphospholipid syndrome (APS) ( n = 24), and mixed connective tissue disease (MCTD) ( n = 9). The main intention is to search for biomarkers for specific rheumatic diseases. Cytokine and growth factor levels were determined using specific ELISA kits., Results: Statistically significant differences in VEGF and IL-35 concentrations occurred between patients with APS vs. RA and SLE vs. RA. There was a significant high positive correlation between the concentration of BAFF and TNF-α ( r = 0.77, p < 0.0000) in patients with APS, as well as in patients with SLE ( r = 0.55, p = 0.00)., Conclusions: BAFF and TNF-α may be promising biomarkers in patients with APS and VEGF in patients with RA. Additionally, IL-35 may be a useful marker for the diagnosis of APS. Positive correlation of BAFF and TNF-α concentrations in APS and SLE potentially indicates much more similar etiopathogenesis of these diseases than it could be previously predicted., Competing Interests: The authors declare no conflict of interest.

Objectives: The Central Sensitization Inventory (CSI) is a new, simple clinimetric instrument intended to help doctors who deal with pain of unclear origin. It may be particularly useful when there is a large component of neuropathic pain and to assess non-specific symptoms associated with the phenomenon of central sensitization known under the common name of the central sensitization syndrome. The aim of this study is to perform translation of the CSI into Polish, its cultural adaptation and its preparation for further validation. The proposed adaptation of the scale may be applied both at the clinical level and at the level of primary care., Material and Methods: The CSI translation process took place in several stages. Firstly, the text of the questionnaire was translated from English to Polish by five independent translators. Secondly, the optimal version of the text was determined and, at the third stage, it was submitted to a linguist in order to assess it in the context of the idiomatic and semantic clarity. Thirdly, the translation was passed on to a native speaker who verified the congruence of the Polish translation with its original version. At a later stage, the effect of translating the scale and its usefulness were discussed by a group of experts in order to adapt a cultural tool. The final step was to provide it to be completed and evaluated by twenty anonymous patients with the aim of pre-assessing the level of its understanding., Results: The final result of the undertaken activities is the Polish version of the CSI ready for validation., Conclusions: After the multistage preparation and thorough verification of the Polish questionnaire at conceptual, empirical, semantic and idiomatic levels, necessary due to numerous cultural and linguistic differences, the Polish translation of the CSI seems to be a product ready for further validation and introduction to clinical practice., Competing Interests: The authors declare no conflict of interest.

Background: An accurate diagnosis of the leading health condition and comorbidities is a prerequisite for safe and effective rehabilitation. The problem of diagnostic errors in physical and rehabilitation medicine (PRM) has not been addressed sufficiently. The responsibility of a referring physician is to determine indications and contraindications for rehabilitation., Aim: To assess the rate of and risk factors for inaccurate referral diagnoses (RD) in patients referred to a rehabilitation facility. We hypothesized that inaccurate RD would be more common in patients: 1) referred by non-PRM physicians; 2) waiting longer for the admission; 3) older patients., Design: Retrospective observational study., Population: One thousand randomly selected patients admitted between 2012 and 2016 to a day-rehabilitation center (DRC)., Setting: University DRC specialized in musculoskeletal diseases., Methods: On admission all cases underwent clinical verification of RD. Inappropriateness regarding primary diagnoses and comorbidities were noted. Influence of several factors affecting probability of inaccurate RD was analyzed with multiple binary regression model applied to 6 categories of diseases., Results: The rate of inaccurate RD was 25.2%. Higher frequency of inaccurate RD was noted among patients referred by non-PRM specialists (30.3% vs. 17.3% in cases referred by PRM specialists). Application of logit regression showed highly significant influence of the specialty of a referring physician on the odds of inaccurate RD (joint Wald Test χ2 (6)=38.98, P value =0.000), controlling for the influence of other variables. This may reflect a suboptimal knowledge of the rehabilitation process and a tendency to neglect of comorbidities by non-PRM specialists. The rate of inaccurate RD did not correlate with time between referral and admission (joint Wald Test of all odds ratios equal to 1, χ2 (6)=5.62, P value =0.467), however, mean and median waiting times were relatively short (35.7 and 25 days respectively). A high risk of overlooked multimorbidity was revealed in elderly patients (all odds ratios for variable age significantly higher than 1). Hypotheses 1 and 3 were confirmed., Conclusions: Over 25% of patients referred to DRC had inaccurate RD. Risk factors for inaccurate RD include referral by a non-PRM specialist and elderly age., Clinical Rehabilitation Impact: Verification of RD should be routinely introduced to PRM practice.

Appropriate health knowledge (HK) and health perceptions (HP) of patients with spinal cord injury (SCI) are linked to health-related behaviors, compliance, the involvement of caregivers and efficacy of prophylaxis, and management of secondary conditions. The significance of factors determining the efficacy of educational interventions in patients with SCI is underestimated. This systematic literature review aims at identification of determinants of HK and HP among patients with SCI. We identified 16 papers with quantitative HK and HP measurements conclusive in the identification of HK and HP determinants in individuals with SCI. Better HK and HP correlated with health condition-related variables (traumatic SCI, history of secondary conditions, except depression), body functions and structures (tetraplegia, incomplete deficit), activities (independence in daily living activities, ability of locomotion on a wheelchair, inability to walk), social and vocational participation, environmental factors (access to a computer with Internet connection, living in a big city, being married, healthcare recently received), and personal factors (younger age among adults, living with SCI for a longer time, younger age at SCI onset, higher educational level, internal locus of control). Limitations encountered included high nonresponse rates among the patients enrolled, and use of heterogeneous and nonvalidated tools. The results of these studies do not cover the entire scope of possible interactions and exclusively apply univariate correlations. The paucity and methodological limitations of studies conclusive in the identification of HK and HP determinants in SCI patients and the development of new approaches to information and education warrant more high-quality research on the basis of multivariate analyses.
