Our working hypothesis was that IT is a valid alternative to GT when GT is not feasible.Patients and Methods: This was a single-blind, randomized study. We recruited 52 women with POP, without significant comorbidity, and no participation in any structured exercise program within the previous 6 months. They were assigned randomly to IT or GT groups (n = 26 each). Distribution of age (IT: 68± 4, GT: 67± 8 years) and body mass index (IT: 23.0± 2.5, GT: 21.4± 5.1) was similar between groups. Each group performed the exercise program in two 1-hour sessions per week for 18 months. Primary outcome measure was Health-Related Quality of Life (HRQoL), as measured by the Short Osteoporosis Quality of Life Questionnaire. Secondary outcome measures focused on domains acknowledged to influence HRQoL (disability, fear of falling, weekly physical activity, physical function) or the effectiveness of the exercise program (retention, adherence, and safety). Significance level was set at p < 0.05.Results: No significant differences were observed between IT and GT groups for any domain. Retention, adherence, and safety were also similar. HRQoL, disability and fear of falling did not change between baseline and follow-up for either group. However, for both groups, physical function (knee flexion, shoulder mobility) and functional capacity (6-minute walking test) improved. Weekly physical activity levels increased from moderate range at baseline to intense at final assessment for both groups.Conclusion: IT and GT supervised exercise programs for women with POP provide similar effectiveness, participation and safety. Hence, both modalities should be considered for future translation in clinical practice of exercise recommendations for POP.Keywords: coaching, encouragement, exercise, physical activity, postmenopausal osteoporosis, quality of life

Exercise might be the most promising non-pharmaceutic intervention to address the large variety of risk factors related to the pronounced estradiol decline during peri- and early-postmenopause. The aim of this study was to determine the effect of an 18-month multipurpose exercise program on risk factors and symptoms related to the menopausal transition. Fifty-four women 1– 5 years postmenopause with osteopenia or osteoporosis were randomly assigned 1) to a high impact weight-bearing/high-intensity/velocity resistance training group (EG: n=27) exercising three times a week or 2) to an attendance control group (CG: n=27) that performed low-intensity exercise once a week. Both groups were supplemented with cholecalciferol and calcium. The primary study endpoint was bone mineral density (BMD) at lumbar spine (LS) and total hip, secondary outcomes were lean body mass (LBM), total and abdominal body percentage, metabolic syndrome Z-Score (MetS-Z), menopausal symptoms and muscle strength and power. Due to COVID-19, the study was stopped after 13 months. We observed significant effects for BMD-LS (EG: 0.002± .018 versus CG: − .009± 0.018 mg/cm2, p=0.027) but not for BMD total hip (EG: − 0.01± .016 versus CG: − .009± 0.020 mg/cm2, p=0.129). LBM improved significantly in the EG and decreased in the CG (0.39± 1.08 vs − 0.37± 1.34 kg, p=0.026). Total and abdominal body fat improved significantly in the EG and was maintained in the CG (− 1.44± 1.49 vs − 0.02± 1.55 kg, p=0.002 and -1.50± 2.33 vs 0.08± 2.07 kg, p=0.011). Significant effects in favor of the EG were also determined for menopausal symptoms (p=0.029), hip/leg extension strength (p< 0.001) and power (p< 0.001). However, changes of the MetS-Z did not differ significantly (p=0.149) between EG and CG. In summary, with minor exceptions, we demonstrated the effectiveness of a multipurpose exercise protocol dedicated to early-postmenopausal women on various risk factors and complaints related to the menopausal transition.Keywords: multipurpose exercise, bone mineral density, early postmenopause

The study population was divided into three groups according to the risk of falling, assessed through the Elderly Fall Screening Test (EFST): low risk (EFST score=0– 1); moderate risk (EFST=2– 3); high risk (EFST=4– 5). Outcome measures were: 4-meter gait speed (4MGS); unipedal stance time (UST); number of falls in the previous year; previous fragility fractures; ongoing pharmacological therapy.Results: We analyzed 753 women (mean aged 70.1± 9.2 years): 378 (50.2%) at low risk of falling, 247 (32.8%) at moderate risk, and 128 (17.0%) at high risk. 4MGS and UST resulted as pathological in the 93.9% and 99.2%, respectively, of women at high risk. There were significant differences among groups for both outcomes (p< 0.001). There was also a significant difference among groups (p< 0.001) in terms of previous falls and fragility fractures. Lastly, there were significant differences (p< 0.05) among groups in using antihypertensive drugs, antiplatelet agents, anticoagulants, antidepressants, anti-osteoporotic drugs, and vitamin D, and/or calcium supplementation.Conclusion: Physical performance, prevalence of falls and fragility fractures, and an assessment of pharmacological therapy should be investigated in post-menopausal women because of their significant correlation with risk of falling.Keywords: accidental falls, osteoporosis, walking speed, fractures, bone, rehabilitation

Stroke is a major cause of disability. Limited motor recovery in the paretic upper limb accounts for a large proportion of the disabling sequelae. Over the past few years, improvements in our understanding of the mechanisms underlying cortical plasticity and the relationship between brain activity and behavioral observations have resulted into major improvements in neurorehabilitation practice. Intensity and specificity of motor training are important to achieve recovery of motor functions. Greater intensity of upper extremity training and repetitive task training in stroke survivors have been shown to be associated with functional improvements and cortical reorganization. Furthermore, the degree of functional recovery has been correlated with magnitude of motor cortical reorganization. Constraint-induced movement therapy (CIMT), robotics and virtual reality training are new approaches that offer great potential for neurorehabilitation. Another promising strategy for enhancing motor recovery is non-invasive brain stimulation. Two non-invasive techniques of inducing electrical currents into the brain (repetitive transcranial magnetic stimulation and transcranial direct current stimulation) have proven to be promising for inducing long-lasting plastic changes in motor systems. Furthermore, brain stimulation combined with motor practice could lead to more remarkable and outlasting clinical gains. The aim of this review is to summarize the state of the art in restorative interventions that focus on improving upper-extremity function after a stroke. [ABSTRACT FROM AUTHOR]

Background: The treatment of a malignant bone tumor in the distal aspect of the femur often requires great sacrifice of bone and muscle. The extent of quadriceps removal has been reported to influence the long-term functional efficiency of a patient's gait. The objective of the present study was to determine gait function as it relates to the residual quadriceps strength and to the specific component or components of the quadriceps removed in patients treated with total knee replacement because of a malignant bone tumor in the distal aspect of the femur.Methods: Sixteen patients were evaluated after implantation of a modular hinged cementless knee prosthesis. The patients were assigned to two groups on the basis of the different components of the quadriceps muscle that were resected. Group 1 consisted of five patients who had removal of the vastus medialis and the vastus intermedius and two who had removal of the vastus medialis only. Group 2 consisted of nine patients who had removal of the vastus lateralis and the vastus intermedius. Residual muscular strength about the treated knee was measured by voluntary maximum contraction isometric testing. Foot-ground reaction forces, kinematic and kinetic findings, and electromyographic activity during free-speed walking were recorded.Results: The kinematic study showed that the patients in Group 1 tended to have a stiff-knee gait during stance, whereas those in Group 2 (in which the vastus medialis was spared) had a more regular flexion-extension knee pattern. Electromyographic findings showed that a higher percentage of patients in Group 1 had reduced or absent rectus femoris activity during the loading response. Compared with the contralateral side, knee-extension strength in the treated limb was decreased in both groups. However, there were no significant differences between the groups with respect to the pattern of strength loss.Conclusions: Good gait function can be achieved in patients with a distal femoral tumor that is treated with distal femoral resection, partial excision of the quadriceps, and total knee arthroplasty with insertion of a hinged prosthesis. Patients in whom the vastus lateralis and vastus intermedius were removed had better gait performance and a more physiological knee-loading pattern than did patients in whom the vastus medialis was removed.

Background: Flexed posture commonly increases with age and is related to musculoskeletal impairment and reduced physical performance. The purpose of this clinical study was to systematically compare the effects of a physical activity program that specifically address the flexed posture that marks a certain percentage of elderly individuals with a non specific exercise program for 3 months.Methods: Participants were randomly divided into two groups: one followed an Adapted Physical Activity program for flexed posture and the other one completed a non-specific physical activity protocol for the elderly. A multidimensional clinical assessment was performed at baseline and at 3 months including anthropometric data, clinical profile, measures of musculoskeletal impairment and disability. The instrumental assessment of posture was realized using a stereophotogrammetric system and a specific biomechanical model designed to describe the reciprocal position of the body segments on the sagittal plane in a upright posture.Results: The Adapted Physical Activity program determined a significant improvement in several key parameters of the multidimensional assessment in comparison to the non-specific protocol: decreased occiput-to-wall distance, greater lower limb range of motion, better flexibility of pectoralis, hamstrings and hip flexor muscles, increased spine extensor muscles strength. Stereophotogrammetric analysis confirmed a reduced protrusion of the head and revealed a reduction in compensative postural adaptations to flexed posture characterized by knee flexion and ankle dorsiflexion in the participants of the specific program.Conclusion: The Adapted Physical Activity program for flexed posture significantly improved postural alignment and musculoskeletal impairment of the elderly. The stereophotogrammetric evaluation of posture was useful to measure the global postural alignment and especially to analyse the possible compensatory strategies at lower limbs in flexed posture.

Objective: The primary objective of this randomized controlled trial was to evaluate the effectiveness of tele-rehabilitation (TR) compared to conventional rehabilitation (CT) in reducing pain (as measured by the Numeric Pain Rating Scale [NPRS]) in patients with knee osteoarthritis (OA). Secondary objectives included assessing changes in physical function and quality of life, as measured by the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and the Short Form-36 (SF-36) health survey, respectively., Methods: Fifty-five patients diagnosed with knee OA were randomly allocated to either the TR group ( n  = 29), receiving remote physiotherapy sessions three times a week for four weeks, or the CT group ( n  = 26), undergoing traditional outpatient rehabilitation with the same exercise regimen. Outcomes were measured at baseline and after a three-month follow-up period., Results: At baseline, there were no significant differences between groups in terms of NPRS and WOMAC scores. After three months, both the CT and the TR groups showed significant improvements in pain reduction (NPRS, p  < 0.001), WOMAC score ( p  < 0.001), and in some subscales of the SF-36 (i.e., physical functioning, role limitation attributable to physical problems, energy, and pain)., Conclusion: Tele-rehabilitation is an effective alternative to CT for reducing pain and improving quality of life in patients with knee OA. These findings suggest that TR can be incorporated alongside conventional approaches to provide a comprehensive treatment strategy for managing knee OA, enhancing patient outcomes in various dimensions of well-being.

Continuity of care has been linked to patient satisfaction and self-reported outcomes. Following hip fractures in the elderly, rehabilitation aims at restoring patients' mobility and independence at the pre-fracture level and at the earliest possible time. Despite the potential role of physiotherapists' continuity on functional outcomes, this correlation has not yet been studied in an acute orthopaedic setting. Guaranteeing the presence of the same physical therapist on individual patients is challenging from an organizational point of view. An observational retrospective study was conducted on 129 aged patients (84 ± 8 years) who underwent surgery for proximal hip fracture. Indicators of outcomes were ILOA score at discharge, length of stay and achievement of rehabilitation goals as defined by the Individual Rehabilitation Project. The number of physical therapists taking care of patients was monitored during the patient's hospital stay. No correlation was found between the number of physical therapists and functional goals at discharge. The frequent change of physical therapists providing rehabilitation to elderly patients who underwent surgery for hip fragile fracture is not related to functional outcomes., (© 2024.

Single-limb stance (SLS) is a demanding postural task, widely used for balance assessment in both research and clinical practice. Despite extensive data on elderly and clinical populations, less is known about younger and healthier adults. Our aim in this study was to assess balance during a SLS task among a cohort of healthy adults to determine whether there are age or sex group or testing condition differences in performances. In this cross-sectional study, we involved 120 participants aged 30-65 years and divided them into four age sub-groups with equal numbers of males and females in each. We assessed balance during a 45-s SLS task on a] the Delos Postural Proprioceptive System for both lower limbs in two conditions - open eyes (OE) and closed eyes (CE). We calculated stability (SI) and autonomy (AU) indices and used analysis of variance to determine that there was no significant effect of limb dominance or sex on balance parameters. However, there was a significant interaction effect between age group and testing condition for both SI and AU ( p < .001 for both), with balance worsening as age increased only in the CE condition. These results highlight a pattern of balance decline with age when vision is eliminated from balance performance, underscoring the critical relationship between sensory input and postural control as people age., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

This study aimed to develop and validate the tendinopathy hemophilia detection with ultrasonography (THD-US) protocol for assessing hemophilia-related tendinopathy. Twenty male patients with hemophilic arthropathy underwent ultrasound evaluations of 200 tendons. The THD-US scoring method assessed structural changes, hyperemia, and calcifications, revealing various tendon abnormalities. This protocol provides a standardized, efficient method for assessing tendinopathy in hemophilia patients, potentially improving patient management and outcomes., (© 2024 The Author(s).

The aging process is commonly accompanied by a general or specific loss of muscle mass, force and/or function that inevitably impact on a person's quality of life. To date, various clinical tests and assessments are routinely performed to evaluate the biomechanical status of an individual, to support and inform the clinical management and decision-making process (e.g., to design a tailored rehabilitation program). However, these assessments (e.g., gait analysis or strength measures on a dynamometer) are typically conducted independently from one another or at different time points, providing clinicians with valuable yet fragmented information. We hereby describe a comprehensive protocol that combines both in vivo measurements (maximal voluntary isometric contraction test, superimposed neuromuscular electrical stimulation, electromyography, gait analysis, magnetic resonance imaging, and clinical measures) and in silico methods (musculoskeletal modeling and simulations) to enable the full characterization of an individual from the biomechanical standpoint. The protocol, which requires approximately 4 h and 30 min to be completed in all its parts, was tested on twenty healthy young participants and five elderlies, as a proof of concept. The implemented data processing and elaboration procedures allowing for the extraction of several biomechanical parameters (including muscle volumes and cross-sectional areas, muscle activation and co-contraction levels) are thoroughly described to enable replication. The main parameters extracted are reported as mean and standard deviation across the two populations, to highlight the potential of the proposed approach and show some preliminary findings (which were in agreement with previous literature)., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Davico, Labanca, Gennarelli, Benedetti and Viceconti.)

Background: It has been shown that chronic ankle instability (CAI) leads to abnormalities in neuromuscular control of more proximal joints than the ankle. Although strength of the hip and the ankle muscles has been largely investigated providing concordant results, limited evidence with contrasting results has been reported regarding knee extensor and flexor muscles., Purpose: To investigate maximal and submaximal isometric muscle strength in individuals with CAI., Study Design: Controlled laboratory study., Methods: Fifteen participants with unilateral CAI and 15 healthy matched controls were recruited. To quantify maximal strength, peak forces were recorded during a maximal isometric voluntary contraction of knee extensor and flexor muscles at 30° and 90° of knee flexion and normalized by the body weight of each participant. At both angles, submaximal isometric contractions at 20%, 50%, and 80% of the maximal voluntary isometric contraction were performed to analyze strength steadiness, in terms of coefficient of variation, and strength accuracy, in terms of absolute error. During all the assessments, knee extensor and flexor muscle activation was recorded by means of surface electromyography., Results: Knee flexor maximal isometric strength was significantly lower in the injured limb of individuals with CAI in comparison with healthy controls at both 30° (0.15 ± 0.05 vs 0.20 ± 0.05; P < .05) and 90° (0.14 ± 0.04 vs 0.18 ± 0.05; P < .05). Knee extensor and flexor steadiness was significantly lower (higher coefficient of variation) in both the injured and the noninjured limbs of individuals with CAI in comparison with healthy individuals at 90° and at 30° for knee flexor steadiness of the injured limb. Knee extensor and flexor accuracy was lower (higher absolute error) in both the injured and noninjured limbs of individuals with CAI in comparison with healthy individuals, mainly at 30°, while at 90° it was lower only in the injured limb. No differences between the 2 groups were found for maximal isometric strength of knee extensor muscles, as well as for muscle activations., Conclusion: Individuals with CAI show abnormalities in maximal and submaximal isometric strength of knee flexor muscles, and submaximal strength of the knee extensor muscles. Further studies should deeply investigate mechanisms leading to these abnormalities., Clinical Relevance: Rehabilitation interventions should consider abnormalities of neuromuscular control affecting joints more proximal than the ankle in individuals with CAI., Registration: NCT05273177 (ClinicalTrials.gov identifier)., Competing Interests: The authors declared that they have no conflicts of interest in the authorship and publication of this contribution.

Background: Among non-pharmacological interventions, Multiwave Locked System (MLS) Laser therapy has been used in patients with several musculoskeletal pathologies and in combination with other therapeutical interventions. The effects of sole MLS therapy on pain and function in patients with chronic non-specific low-back pain are unknown., Objective: The objective of this study was to investigate the effects of MLS Laser therapy on pain, function, and disability in patients with chronic non-specific low back pain in comparison to a placebo treatment group., Methods: Forty-five patients were randomized into two groups: the MLS Laser group and the Sham Laser group, undergoing 8 sessions of either a MLS Laser therapy or a Sham Laser therapy, respectively. At the beginning of the therapy (T0), at the end of the therapy (T1), and 1 month after the end of therapy (T2) patients were assessed for low back pain (by means of a VAS scale), function (by means of kinematic and electromyographic assessment of a forward bending movement) and self-reported disability (by means of the Roland-Morris and Oswestry Disability questionnaires)., Results: There was a significant reduction of pain and disability in both groups at T1 and T2 in comparison with T0. At T2 patients in the MLS group showed a significantly lower pain in comparison with patients in the Sham group (VAS = 2.2 ± 2 vs. 3.6 ± 2.4; p< 0.05). No differences between the two groups were found for function and disability., Conclusion: Both MLS Laser and Sham Laser therapies lead to a significant and comparable reduction in pain and disability in patients with chronic non-specific low back pain. However, one month after treatment, MLS Laser therapy has been found to be significantly more effective in reducing pain as compared to sham treatment.
