Introduction In recent years, robot-assisted gait training (RAGT) has been proposed as therapy for balance and gait dysfunctions in people with multiple sclerosis (PwMS). Through this systematic review, we aimed to discuss the impact of RAGT on balance and gait outcomes. Furthermore, characteristics of the training in terms of robots used, participants characteristics, protocols and combined therapeutic approaches have been described. Evidence acquisition As part of the Italian Consensus on robotic rehabilitation "CICERONE" a systematic search was provided in PubMed, the Cochrane Library and PEDro to identify relevant studies published before December 2019. Only randomized control trials (RCT) involving RAGT for PwMS were included. PEDro scale was used to assess the risk of bias and the Oxford Center for Evidence-Based Medicine (OCEBM) was used to assess level of evidence of included studies. Evidence synthesis The search on databases resulted in 336 records and, finally, 12 studies were included. RAGT was provided with Exoskeleton in ten studies (6-40 session, 2-5 per week) and with end-effector in two studies (12 sessions, 2-3 per week) with large variability in terms of participants' disability. All the exoskeletons were combined with bodyweight support treadmill and movement assistance varied from 0% to 100% depending on participants' disability, two studies combined exoskeleton with virtual reality. The end-effector speed ranged between 1.3 and 1.8 km/h, with bodyweight support starting from 50% and progressively reduced. In seven out of twelve studies RAGT was provided in a multimodal rehabilitation program or in combination with standard physical therapy. There is level 2 evidence that RAGT has positive impact in PwMS, reaching the minimally clinically importance difference in Berg Balance Scale, six-minute walking test and gait speed. Conclusions In available RCT, RAGT is mostly provided with exoskeleton devices and improves balance and gait outcomes in a clinically meaningful way. Considering several advantages in terms of safety, motor assistance and intensity of training provided, RAGT should be promoted for PwMS with severe disability in a multimodal rehabilitation context as an opportunity to maximize recovery.

Background: Over recent years numerous patients with severe forms of multiple sclerosis (MS) refractory to conventional therapies have been treated with intense immunosuppression followed by autologous haematopoietic stem cell transplantation (AHSCT). The clinical outcome and the toxicity of AHSCT can be diverse, depending on the various types of conditioning protocols and on the disease phase. Objectives: To report the Italian experience on all the consecutive patients with MS treated with AHSCT with an intermediate intensity conditioning regimen, named BEAM/ATG, in the period from 1996 to 2008. Methods: Clinical and magnetic resonance imaging outcomes of 74 patients were collected after a median follow-up period of 48.3 (range = 0.8–126) months. Results: Two patients (2.7%) died from transplant-related causes. After 5 years, 66% of patients remained stable or improved. Among patients with a follow-up longer than 1 year, eight out of 25 subjects with a relapsing–remitting course (31%) had a 6–12 months confirmed Expanded Disability Status Scale improvement > 1 point after AHSCT as compared with one out of 36 (3%) patients with a secondary progressive disease course ( p = 0.009). Among the 18 cases with a follow-up longer than 7 years, eight (44%) remained stable or had a sustained improvement while 10 (56%), after an initial period of stabilization or improvement with median duration of 3.5 years, showed a slow disability progression. Conclusions: This study shows that AHSCT with a BEAM/ATG conditioning regimen has a sustained effect in suppressing disease progression in aggressive MS cases unresponsive to conventional therapies. It can also cause a sustained clinical improvement, especially if treated subjects are still in the relapsing–remitting phase of the disease.

Guidance on pharmacotherapy of neurobehavioural sequelae post-acquired brain injury (ABI) is limited. Clinicians face the choice of prescribing off-label. This survey assesses prescribing practice and off-label use of psychotropic medications in Italian brain injury rehabilitation centres and factors associated with atypical antipsychotics use.Centres were identified through the roster of the Italian Society for Rehabilitation Medicine. Information was collected through a structured questionnaire. This study calculated the prevalence of centres reporting to use off-label individual medications and unconditional logistic regression Odds Ratio (OR), with 95% confidence interval (95% CI) of atypical antipsychotics use.Psychotropic medications were commonly used. More than 50% of the 35 centres (participation ratio 87.5%) reported to use off-label selected antipsychotics, mostly for agitation (90.5%) and behavioural disturbances (19.0%), and antidepressants, mostly for insomnia (37.5%) and pain (25.0%). Atypical antipsychotic use was directly associated with age40 years (OR = 2.68; 95% CI = 1.25-5.76), recent ABI (1.74; 0.74-4.09), not with reported off-label use (0.98; 0.44-2.18).In clinical practice, the effectiveness and safety of medications, in particular off-label, should be systematically monitored. Studies are needed to improve the quality of evidence guiding pharmacotherapy and to evaluate effectiveness and safety of off-label prescribing.

El presente trabajo evaluó el movimiento de los dientes artificiales en prótesis totales maxilares, sometidas a diversas presiones durante el prensado y el efecto de este en relación al material usado en la inclusión. Treinta y seis réplicas de prótesis totales previamente confeccionadas, fueran divididas en seis grupos: Los grupos G1, G2 y G3 fueron incluidos con yeso tipo III, a una presión de 800, 1.000 y 1.250 kgf respectivamente y los grupos S1, S2 y S3 fueron incluidos con una barrera de silicona y yeso, a una presión de 800, 1.000 y 1.250 kgf, respectivamente. Las prótesis fueron medidas en puntos demarcados previamente en los segundos molares, premolares e incisivo central con el programa de computación gráfica (AutoCad 2000), después de cada etapa: encerado, polimerización y emuflado. La comparación entre estas dos fases permitió observar que: en los grupos (G1 y S1) donde se utilizó la menor presión (800 kgf) ocurrieron las mayores alteraciones en el posicionamiento de los dientes artificiales y que el grupo que mostró menores alteraciones fue cuando se utilizó 1.250 kgf de presión y la inclusión fue con yeso. The present study evaluated artificial teeth movement in complete dentures, submitted to different flasking loading and the effect of these loading pressures on the material used in the flasking procedure. Thirty-six dentures were fabricated and equally divided into six groups: Groups G1, G2 and G3 were processed with type III gypsum and 800, 1000 and 1250 kgf loading pressures, respectively, and groups S1, S2 and S3 were processed with silicone barrier and 800, 1000 and 1250 kgf loading pressures, respectively. In order to evaluate the artificial teeth movement, measurements were performed from previously determined points down in the second molars tips and in the second pre-molars cusps and in the central incisor. Those points were scanned (Scan Jet 6100C - Hewlett Packard) and then the measurements were performed and analyzed through the use of the AutoCad 2000 software, during the wax and the post-polymerization phases. The comparison between these two phases allowed the following observations: in groups (G1 and S1) where less loading pressure was used (800 kgf), the movements in the artificial teeth positions were the highest, and the group that presented the lowest changes was the one processed with type III gypsum and 1250 kgf loading pressure.

Background: The increased survival after a severe acquired brain injury (sABI) raise the problem of making most effective the treatments in Intensive Care Unit (ICU)/Neurointensive Care Unit (NICU), also integrating rehabilitation care. Despite previous studies reported that early mobilization in ICU was effective in preventing complications and reducing hospital stay, few studies addressed the rehabilitative management of sABI patients in ICU/NICU. Aim: To collect clinical and functional data about the early rehabilitative management of sABI patients during ICU/NICU stay. Design. Prospective, observational, multicenter study. Setting: Fourteen facilities supplied by intensive neurorehabilitation units and ICU/NICUs. Population : Consecutive sABI patients admitted to ICU/NICU. Methods: Patients were evaluated at admission and then every 3-5 days. Clinical, functional and rehabilitative data, including Glasgow Coma Scale (GCS), Disability Rating Scale (DRS), The Rancho Los Amigos Levels of Cognitive Functioning Scale (LCF), Early Rehabilitation Barthel Index (ERBI), Glasgow Outcome scale (GOS) and Functional Independence Measure (FIM) were collected. Results : One hundred and two patients (F/M 44/58) were enrolled. The mean duration of ICU stay was 24.7±13.9 days and the first rehabilitative evaluation occurred after 8.7±8.8 days. Regular postural changes and multijoint mobilization were prescribed in 63.7% and 64.7% cases, respectively. The mean session duration was 38±11.5 minutes. Swallowing evaluation was performed in 14.7% patients, psychological support was provided to 12.7% of patients' caregivers, while 17.6% received a psycho-educational intervention, and 28.4% were involved in interdisciplinary team meetings. The main discharge destinations were Severe Acquired Brain Injury rehabilitation units for 43.7%, intensive neurorehabilitation units for 20.7%. Conclusions: Data showed that early rehabilitation was not diffusely performed in sABI subjects in ICU/NICU and rehabilitative interventions were variable; one-third of subjects were not referred to dedicated rehabilitation unit at discharge. Clinical Rehabilitation Impact : The study stresses the need to spread and implement a rehabilitative culture also for critical ill patients due to neurological diseases.

Turkey red blood cell passive haemagglutination assays (TRBC-HA) were carried out on serum samples from 873 injured patients in order to compare individual prophylactic treatment against tetanus based on the anti-tetanus antibody levels with interventions based on anamnestic criteria. The results showed a great difference: according to the anamnesis 124 persons (14.2%) were protected, 253 (29%) were partially protected, and 496 (56.8%) were unprotected; according to the TRBC-HA assay, 479 (54.9%) were protected, 279 (32%) partially protected, and 115 (13.2%) unprotected.The efficiency of the prophylactic treatments given on the basis of the two criteria was also compared in a study of 129 injured patients who were divided in two groups: group 1 (50 patients) received 250 IU of human tetanus immunoglobulin (HTI) regardless of their tetanus immunity, and group II (79 patients) received appropriate or no treatment depending on the level of anti-tetanus antibodies determined by TRBC-HA assay. The results showed that prophylactic interventions based on the anti-tetanus antibody levels can give protection in 100% of injured patients at minimum cost and risk.

Introduction Postural instability is a cardinal feature of Parkinson's disease, together with rest tremor, rigidity and bradykinesia. It is a highly disabling symptom that becomes increasingly common with disease progression and represents a major source of reduced quality of life in patients with Parkinson's disease. Rehabilitation aims to enable patients with Parkinson's disease to maintain their maximum level of mobility, activity and independence. To date, a wide range of rehabilitation approaches has been employed to treat postural instability in Parkinson's disease, including robotic training. Our main aim was to conduct a systematic review of current literature about the effects of robot-assisted gait training on postural instability in patients with Parkinson's disease. Evidence acquisition A systematic search using the following MeSH terms "Parkinson disease," "postural balance," "robotics," "rehabilitation" AND string "robotics [mh]" OR "robot-assisted" OR "electromechanical" AND "rehabilitation [mh]" OR "training" AND "postural balance [mh]" was conducted on PubMed, Cochrane Library and Pedro electronic databases. Full text articles in English published up to December 2020 were included. Data about patient characteristics, robotic devices, treatment procedures and outcome measures were considered. Every included article got checked for quality. Level of evidence was defined for all studies. Evidence synthesis Three authors independently extracted and verified data. In total, 18 articles (2 systematic reviews, 9 randomized controlled trials, 4 uncontrolled studies and 3 case series/case reports) were included. Both end-effector and exoskeleton devices were investigated as to robot-assisted gait training modalities. No clear relationship between treatment parameters and clinical conditions was observed. We found a high level of evidence about the effects of robot-assisted gait training on balance and freezing of gait in patients with Parkinson's disease. Conclusions This systematic review provides to the reader a complete overview of current literature and levels of evidence about the effects of robot-assisted gait training on postural instability issues (static and dynamic balance, freezing of gait, falls, confidence in activities of daily living and gait parameters related to balance skills) in patients with Parkinson's disease.

Aims: to assess occurrence and clinical correlates of neurogenic heterotopic ossifications (NHO) in patients with prolonged disorder of consciousness (DoC). Design: multi-center cross-sectional observational study. Setting: 23 intensive neurorehabilitation units. Subjects: 287 patients with prolonged disorder of consciousness (DoC; 150 in vegetative state, VS, and 128 in minimally conscious state, MCS) of different etiology (vascular=125, traumatic=83, anoxic=56, others=14). Main Measures: clinical evidence of NHO confirmed by standard radiological and/or sonographic evaluation; Coma Recovery Scale-Revised; Disability Rating Scale (DRS); Early Rehabilitation Barthel Index; presence of ventilator support, spasticity, bone fractures and paroxysmal sympathetic hyperactivity. Results: 31 patients (11.2%) presented NHO. Univariate analyses showed that NHO was associated with VS diagnosis, traumatic etiology, high DRS category and total score, and high occurrence of limb spasticity and bone fractures. A cluster-corrected binary logistic regression model (excluding spasticity available in a subset of patients) showed that only lower DRS total score and presence of bone fractures were independently associated with NHO. Conclusions: NHO are relatively frequent in patients with DoC, and are independently associated with functional disability, bone fractures and spasticity. These findings contribute to identifying patients with DoC prone to develop NHO and requiring special interventions to improve functional recovery.

Aim: to assess overall clinical complexity of patients with acquired disorders of consciousness (DoC) in vegetative state/unresponsive wakefulness syndrome (VS/UWS) vs. minimally conscious state- MCS) and in different etiologies. Design: Multi-center cross-sectional observational study. Setting: 23 intensive neurorehabilitation units. Subjects: 264 patients with DoC in the post-acute phase: VS/UWS = 141, and MCS = 123 due to vascular (n = 125), traumatic (n = 83) or anoxic (n = 56) brain injury. Main Measures: Coma Recovery Scale-Revised, and Disability Rating Scale (DRS); presence of medical devices (e.g., for eating or breathing); occurrence and severity of medical complications. Results: patients in DoC, and particularly those in VS/UWS, showed severe overall clinical complexity. Anoxic patients had higher overall clinical complexity, lower level of responsiveness/consciousness, higher functional disability, and higher needs of medical devices. Vascular patients had worse premorbid clinical comorbidities. The two etiologies showed a comparable rate of MC, higher than that observed in traumatic etiology. Conclusion: overall clinical complexity is significantly higher in VS/UWS than in MCS, and in non-traumatic vs. traumatic etiology. These findings could explain the worse clinical evolution reported in anoxic and vascular etiologies and in VS/UWS patients and contribute to plan patient-tailored care and rehabilitation programmes.
