Abstract
Introduction Charcot-Marie-Tooth disease (CMT) is an inherited neuropathy that affects the sensory and motor nerves. It can be considered the most common neuromuscular disease, with a prevalence of 1/2500. Methods Considering the absence of a specific medical treatment and the benefits shown by physical activity in this population, a systematic review was completed using several search engines (Scopus, PubMed, and Web of Science) to analyze the use, effectiveness, and safety of a training program performed in telecoaching (TC). TC is a new training mode that uses mobile devices and digital technology to ensure remote access to training. Results Of the 382 studies identified, only 7 met the inclusion criteria. The effects of a TC training program included improvements in strength, cardiovascular ability, and functional abilities, as well as gait and fatigue. However, the quality of the studies was moderate, the size of the participants in each study was small, and the outcome measured was partial. Discussion Although many studies have identified statistically significant changes following the administration of the TC training protocol, further studies are needed, with appropriate study power, better quality, and a higher sample size.

Abstract
Background It is unclear whether prolonged periods of training can be well tolerated. In Charcot-Marie Tooth disease (CMT). We report the effects of an 8-month, adapted motor activity (AMA) program in a 16-years-old CMT1A male patient. The program included strength, mobility, and balance training (two sessions per week, 1 h per session). Measures Walking ability and walking velocity (Six-Minute Walking Test-6MWT, Ten Meters Walking Test-10 mW T), balance (Y-Balance Test-YBT, Berg Balance Scale-BBS), functional mobility (Short Physical Performance Battery-Short physical performance battery), fatigue (Checklist Individual strength questionnaire - CIS20R), health and quality of life (Short Form Health Survey 36 questionnaire-SF-36) were evaluated in three moments: before (T0), after 5 (T1) and 8 (T2) months of adapted motor activity. Dorsal and plantar foot flexion strength (Maximal Voluntary Contraction-maximum voluntary contraction) and neuromuscular functions (Electromyography-sEMG, interpolated twitch technique-ITT) were measured at T1 and T2. Results Relative to T0, an amelioration of walking ability (6MWT, +9,3%) and balance (with improvements on Y-balance composite normalized mean reach of the right and left limb of 15,3% and 8,5%, respectively) was appreciable. Relative to T1, an increase in foot strength in three out of four movements (right plantar flexion, +39,3%, left plantar flexion, +22,7%, left dorsal flexion, 11,5%) was observed. Concerning voluntary muscle activation, a greater recruitment in the left, unlike right, medial gastrocnemius was observed. Conclusion Results suggest the safety of an 8-month AMA program in a young patient affected by CMT1A.

Abstract
INTRODUCTION Charcot-Marie-Tooth (CMT) disease is classified considering the neurophysiological and histological findings, the inheritance pattern and the underlying genetic defect. In recent years, with the advent of next generation sequencing, genetic complexity has increased exponentially, expanding the knowledge about disease pathways, and having an impact in clinical management. The aim of this guide is to offer recommendations for the diagnosis, prognosis, monitoring and treatment of this disease in Spain. MATERIAL AND METHODS This consensus guideline has been developed by a multidisciplinary panel encompassing a broad group of professionals including neurologists, neuropediatricians, geneticists, rehabilitators, and orthopaedic surgeons. RECOMMENDATIONS The diagnosis is based in the clinical characterization, usually presenting with a common phenotype. It should be followed by an appropriate neurophysiological study that allows for a correct classification, specific recommendations are established for the parameters that should be included. Genetic diagnosis must be approached in sequentially, once the PMP22 duplication has been ruled out if appropriate, a next generation sequencing should be considered taking into account the limitations of the available techniques. To date, there is no pharmacological treatment that modifies the course of the disease, but symptomatic management is important, as are the rehabilitation and orthopaedic considerations. The latter should be initiated early to identify and improve the patient's functional impairments, including individualised exercise guidelines, orthotic adaptation, and assessment of conservative surgeries such as tendon transpositions. The follow-up of patients with CMT is exclusively clinical, ancillary testing are not necessary in routine clinical practice.

Abstract
INTRODUCTION/AIMS People with Charcot-Marie-Tooth Disease (CMT) frequently report problems with balance, which lead to an increased risk of falls. Evidence is emerging of training interventions to improve balance for people with CMT, but to date all have relied on clinic-based treatment and equipment. This proof-of-concept study explored whether a multi-modal program of proprioceptive rehabilitation and strength training can be delivered at home, to improve balance performance in people with CMT Type 1A. METHODS Fourteen participants with CMT Type 1A were recruited into this randomized, two-arm study. Baseline assessments included measures of disease severity, posturography, physical function, and patient-reported outcome measurements. All participants received one falls education session. Participants were randomized to either 12 weeks of balance training or 12 weeks of usual activities. The intervention comprised a home-based, multi-sensory balance training and proximal strengthening program, supported by three home visits from a physiotherapist. RESULTS Thirteen participants completed the study. The intervention was successfully implemented and well tolerated, with high participation levels. Functional measures of balance and walking showed strong effect sizes in favor of the training group. Posturography testing demonstrated moderate improvements in postural stability favoring the intervention group. Inconsistent changes were seen in lower limb strength measures. DISCUSSION The intervention was feasible to implement and safe, with some evidence of improvement in balance performance. This supports future studies to expand this intervention to larger trials of pragmatic, home-delivered programs through current community rehabilitation services and supported self-management pathways.

Abstract
Charcot-Marie-Tooth (CMT) disease is one of the most common inherited neuropathies and can lead to progressive muscular weakness, pes cavus, loss of deep tendon reflexes, distal sensory loss, and gait impairment. There are still no effective drugs or surgical therapies for CMT, and supportive treatment is limited to rehabilitative therapy and surgical treatment of skeletal deformities. Many rehabilitative therapeutic approaches have been proposed, but timing and cadence of rehabilitative intervention are not clearly defined, and long-term follow-up is lacking in literature. The aim of this real-practice retrospective study was to assess the effectiveness of an intensive neurorehabilitation protocol on muscle strength and functioning in CMT patients. We analyzed data of patients with diagnosis of mild to moderate CMT. The rehabilitation program lasted 2-4 h a day, 5 days a week, for 3 weeks and consisted of manual treatments, strengthening exercises, stretching, core stability, balance and resistance training, aerobic exercises, and tailored self-care training. Data were collected at baseline (T0), after treatment (T1), and at the 12-month mark (T2) in terms of the following outcome measures: muscle strength, pain, fatigue, cramps, balance, walking speed, and ability. We included 37 CMT patients with a median age of 50.72 ± 13.31 years, with different forms: demyelinating (n = 28), axonal (n = 8), and mixed (n = 1). After intensive rehabilitation treatment, all outcomes significantly improved. This improvement was lost at the 1-year mark. Taken together, these findings suggest that an intensive rehabilitation program improves short-term symptoms and functional outcomes in a cohort of inpatients affected by mild to moderate CMT.

Abstract
Charcot-Marie-Tooth (CMT) disease, also known as hereditary motor sensory neuropathy, is a group of rare genetically heterogenous diseases characterized by progressive muscle weakness and atrophy, along with sensory deficits. Despite extensive pre-clinical and clinical research, no FDA-approved therapy is available for any CMT type. We previously identified C1ORF194, a novel causative gene for CMT, and found that both C1orf194 knock-in (I121N) and knockout mice developed clinical phenotypes similar to those in patients with CMT. Encouraging results of adeno-associated virus (AAV)-mediated gene therapy for spinal muscular atrophy have stimulated the use of AAVs as vehicles for CMT gene therapy. Here, we present a gene therapy approach to restore C1orf194 expression in a knockout background. We used C1orf194-/- mice treated with AAV serotype 9 (AAV9) vector carrying a codon-optimized WT human C1ORF194 cDNA whose expression was driven by a ubiquitously expressed chicken β-actin promoter with a CMV enhancer. Our preclinical evaluation demonstrated the efficacy of AAV-mediated gene therapy in improving sensory and motor abilities, thus achieving largely normal gross motor performance and minimal signs of neuropathy, on the basis of neurophysiological and histopathological evaluation in C1orf194-/- mice administered AAV gene therapy. Our findings advance the techniques for delivering therapeutic interventions to individuals with CMT.

Association of Body Mass Index With Disease Progression in Children With Charcot-Marie-Tooth Disease. Neurology 2023; 101:e717-e727. [PMID: 37380432 PMCID: PMC10437011 DOI: 10.1212/wnl.0000000000207488] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2022] [Accepted: 04/20/2023] [Indexed: 06/30/2023] Open
Abstract
BACKGROUND AND OBJECTIVES The aim of this study was to evaluate the impact of body mass index (BMI) on disease progression over 2 years in children with Charcot-Marie-Tooth disease (CMT). METHODS BMI was classified in 242 participants aged 3-20 years with CMT enrolled in the Inherited Neuropathy Consortium, using the International Obesity Task Force (based on adult BMI values, kg/m2) criteria. Groups were categorized as severely underweight (BMI <17 kg/m2), underweight (BMI ≥17 to <18.5 kg/m2), healthy weight (BMI ≥18.5 to <25 kg/m2), overweight (BMI ≥25 to <30 kg/m2), and obese (BMI ≥30 kg/m2). Disease severity was assessed using the CMT Pediatric Scale (CMTPedS), a clinical outcome assessment of disability (0-44 points, mild to severe). RESULTS At baseline, compared with individuals being of a healthy weight (mean CMTPedS 15.48, SD 9.22), children who were severely underweight (mean CMTPedS difference 9.03, 95% CI 0.94-17.12; p = 0.02), underweight (mean CMTPedS difference 5.97, 95% CI 0.62-11.31; p = 0.02), or obese (mean CMTPedS difference 7.96, 95% CI 1.03-14.88; p = 0.015) exhibited greater disability. At 2 years, compared with individuals being of a healthy weight (mean CMTPedS 17.53, SD 9.41), children who were severely underweight exhibited greater disability (mean CMTPedS difference 9.27, 95% CI 0.90-17.64; p = 0.02). Over the 2-year periods, the mean CMTPedS for the whole sample deteriorated by 1.72 points (95% CI 1.09-2.38; p < 0.001), with severely underweight children progressing at the fastest rate (mean CMTPedS change of 2.3, 95% CI 1.53-6.13; p = 0.21). In children who did not have a change in BMI categories over 2 years (69% of sample), CMTPedS scores deteriorated faster in those who were severely underweight (mean CMTPedS change 6.40 points, 95% CI 2.42-10.38; p = 0.01) than those of healthy weight (mean CMTPedS change 1.79 points, 95% CI 0.93-2.69; p < 0.001). For children who changed BMI categories (31% of sample), CMTPedS scores deteriorated faster in children who became overweight/obese (mean CMTPedS change 2.76 points, 95% CI 0.11-5.41; p = 0.031). DISCUSSION Children with CMT who were severely underweight, underweight, or obese exhibited greater disability at baseline. Over the 2-year period in those whose BMI remained stable, severely underweight children deteriorated at the fastest rate. For children who changed BMI categories over the 2 years, CMTPedS scores deteriorated faster in children who became overweight/obese. Interventions that maintain or improve BMI toward healthy weight may reduce disability in children with CMT.

Efficacy of aerobic exercise on aerobic capacity in slowly progressive neuromuscular diseases: A systematic review and meta-analysis. Ann Phys Rehabil Med 2023; 66:101637. [PMID: 35091111 DOI: 10.1016/j.rehab.2022.101637] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2021] [Revised: 10/29/2021] [Accepted: 11/16/2021] [Indexed: 12/26/2022]
Abstract
BACKGROUND Aerobic exercise aims to improve aerobic capacity. OBJECTIVE To summarize the evidence on the efficacy of aerobic exercise on aerobic capacity in slowly progressive neuromuscular diseases (NMDs). METHODS We searched the electronic databases MEDLINE, EMBASE, SPORTDiscus and Web of Science Conference Proceedings Index for articles published up to June 17, 2021, selecting randomized controlled trials that included adults with slowly progressive NMDs and compared aerobic exercise to no aerobic exercise. The primary outcome was peak oxygen uptake (VO2peak) directly post-intervention. Secondary outcomes included other peak test parameters, submaximal test parameters, long-term outcomes ≥8 weeks post-intervention, adherence and adverse events. Meta-analyses were performed for the primary outcome and for secondary outcomes when reported in more than 2 studies. Risk of bias was assessed with the Cochrane Risk of Bias tool and quality of evidence according to GRADE. RESULTS Nine studies were included (195 participants with 8 different NMDs). Eight studies were rated at high risk of bias and 1 study was rated at some concerns. Duration of exercise programs ranged from 6 to 26 weeks, with 3 weekly training sessions of 20 to 40 min, based on maximal capacity. Meta-analyses revealed short-term moderate beneficial effects of aerobic exercise on VO2peak (standardized mean difference [SMD] 0.55, 95% CI 0.23; 0.86) and peak workload (SMD 0.61, 95% CI 0.24; 0.99). Long-term effects were not assessed. Most training sessions (83-97%) were completed, but time spent in target intensity zones was not reported. Included studies lacked detailed adverse event reporting. CONCLUSIONS There is low-quality evidence that aerobic exercise is safe and leads to moderate improvement of aerobic capacity directly post-intervention in slowly progressive NMDs, but the long-term efficacy remains unclear. Detailed information about the time spent in target intensity zones and adverse events is lacking. PROSPERO CRD42020200083.

Abstract
The aim of this study was to explore and describe the exercise behaviours and barriers in people with Charcot-Marie-Tooth disease (CMT), with a particular focus on resistance training (RT). Ninety-four Australian adults with a diagnosis of CMT completed an online survey. Fifty-seven percent of respondents reported performing some form of RT each week. Those performing RT engaged in more aerobic activity (P≤0.01) and were involved in longer periods of structured exercise (P<0.01) compared to those not performing RT. The RT group was more likely to perceive their exercise levels as acceptable (P<0.01), that following a program was important (P=0.02), and that exercise is beneficial (P=0.04). The RT group were more likely to have been advised to exercise (P=0.02). Common barriers to exercise were fatigue (64.9%), pain (57.4%), motivation (51.1%), and time (46.8%). RT status did not influence the type of barriers experienced. Weekly RT time was positively associated with exercise satisfaction (r=0.43, P<0.01) and walking distance prior to resting (r=0.29, P=0.04). The findings suggest that positive exercise experiences, advice, assistance from a trainer, and potentially greater resources may influence participation in RT for people with CMT.

Playing Disability Rugby League with Charcot-Marie-Tooth Disease: A Case Study. Sports (Basel) 2023; 11:sports11020021.

Abstract
Charcot-Marie-Tooth (CMT) disease is a common inherited neurological disorder that causes damage to peripheral nerves. Reports of CMT patients participating in team-based sports such as disability rugby league are scarce. The objective of this case report was to evaluate the benefits of participation in disability rugby league in a 50-year-old male with CMT. Leg muscle mass and strength was worse for the case subject compared to two age-matched CMT participants with an exercise history; however, evidence of greater function in the case subject was observed through better 6-min walk test performance. Performance in a series of sport specific tests was noticeably worse for the case subject compared to a fellow rugby league player (age matched) with cerebral palsy. Inferior in-game performance was observed for the case subject compared to his fellow rugby league player in terms of distance covered, top running speed, and intensity. However, the case subject may have assumed a different role when playing as evident by the different behaviours he displayed during the games (i.e., less player contacts, tackles, or touches, but more passes of the ball). This case study provides information concerning disability rugby league as an adjunctive mode of treatment for CMT populations.

Abstract
Charcot-Marie-Tooth (CMT) is a heterogeneous group of inherited neuropathies that affect the peripheral nerves and slowly cause progressive disability. Currently, there is no effective therapy. Patients' management is based on rehabilitation and occupational therapy, fatigue, and pain treatment with regular follow-up according to the severity of the disease. In the last three decades, much progress has been made to identify mutations involved in the different types of CMT, decipher the pathophysiology of the disease, and identify key genes and pathways that could be targeted to propose new therapeutic strategies. Genetic therapy is one of the fields of interest to silence genes such as PMP22 in CMT1A or to express GJB1 in CMT1X. Among the most promising molecules, inhibitors of the NRG-1 axis and modulators of UPR or the HDACs enzyme family could be used in different types of CMT.

Early targeting of endoneurial macrophages alleviates the neuropathy and affects abnormal Schwann cell differentiation in a mouse model of Charcot-Marie-Tooth 1A. Glia 2022; 70:1100-1116. [PMID: 35188681 DOI: 10.1002/glia.24158] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2021] [Revised: 01/26/2022] [Accepted: 01/31/2022] [Indexed: 12/11/2022]
Abstract
We have previously shown that targeting endoneurial macrophages with the orally applied CSF-1 receptor specific kinase (c-FMS) inhibitor PLX5622 from the age of 3 months onwards led to a substantial alleviation of the neuropathy in mouse models of Charcot-Marie-Tooth (CMT) 1X and 1B disease, which are genetically-mediated nerve disorders not treatable in humans. The same approach failed in a model of CMT1A (PMP22-overexpressing mice, line C61), representing the most frequent form of CMT. This was unexpected since previous studies identified macrophages contributing to disease severity in the same CMT1A model. Here we re-approached the possibility of alleviating the neuropathy in a model of CMT1A by targeting macrophages at earlier time points. As a proof-of-principle experiment, we genetically inactivated colony-stimulating factor-1 (CSF-1) in CMT1A mice, which resulted in lower endoneurial macrophage numbers and alleviated the neuropathy. Based on these observations, we pharmacologically ablated macrophages in newborn CMT1A mice by feeding their lactating mothers with chow containing PLX5622, followed by treatment of the respective progenies after weaning until the age of 6 months. We found that peripheral neuropathy was substantially alleviated after early postnatal treatment, leading to preserved motor function in CMT1A mice. Moreover, macrophage depletion affected the altered Schwann cell differentiation phenotype. These findings underscore the targetable role of macrophage-mediated inflammation in peripheral nerves of inherited neuropathies, but also emphasize the need for an early treatment start confined to a narrow therapeutic time window in CMT1A models and potentially in respective patients.

Abstract
There is still no effective drug treatment available for Charcot-Marie-Tooth neuropathies (CMT). Current management relies on rehabilitation therapy, surgery for skeletal deformities, and symptomatic treatment of pain; fatigue and cramps are frequent complaints that are difficult to treat. The challenge is to find disease-modifying therapies. Several approaches, including gene silencing, to counteract the PMP22 gene overexpression in the most frequent CMT1A type are under investigation. PXT3003 is the compound in the most advanced phase for CMT1A, as a second-phase III trial is ongoing. Gene therapy to substitute defective genes or insert novel ones and compounds acting on pathways important for different CMT types are being developed and tested in animal models. Modulation of the Neuregulin pathway determining myelin thickness is promising for both hypo-demyelinating and hypermyelinating neuropathies; intervention on Unfolded Protein Response seems effective for rescuing misfolded myelin proteins such as P0 in CMT1B. HDAC6 inhibitors improved axonal transport and ameliorated phenotypes in different CMT models. Other potential therapeutic strategies include targeting macrophages, lipid metabolism, and Nav1.8 sodium channel in demyelinating CMT and the P2X7 receptor, which regulates calcium influx into Schwann cells, in CMT1A. Further approaches are aimed at correcting metabolic abnormalities, including the accumulation of sorbitol caused by biallelic mutations in the sorbitol dehydrogenase (SORD) gene and of neurotoxic glycosphingolipids in HSN1.

Abstract
Rare neurological conditions (RNCs) encompass a variety of diseases that differ in progression and symptoms but typically include muscle weakness, sensory and balance impairment and difficulty with coordinating voluntary movement. This can limit overall physical activity, so interventions to address this are recommended. The aim of this study was to agree a core outcome measurement set for physical activity interventions in people living with RNCs. We followed established guidelines to develop core outcome sets. Broad ranging discussions in a series of stakeholder workshops led to the consensus that (1) physical well-being; (2) psychological well-being and (3) participation in day-to-day activities should be evaluated in interventions. Recommendations were further informed by a scoping review of physical activity interventions for people living with RNCs. Nearly 200 outcome measures were identified from the review with a specific focus on activities or functions (e.g, on lower limb function, ability to perform daily tasks) but limited consideration of participation based outcomes (e.g., social interaction, work and leisure). Follow on searches identified two instruments that matched the priority areas: the Oxford Participation and Activities Questionnaire and the Sources of Self-Efficacy for Physical Activity. We propose these scales as measures to assess outcomes that are particularly relevant to assess when evaluating physical activity interventions mong people with RNCs. Validation work across rare neurological conditions is now required to inform application of this core outcome set in future clinical trials to facilitate syntheses of results and meta-analyses.

Abstract
Inherited neuropathies of the Charcot-Marie-Tooth (CMT) type 1 are still untreatable diseases of the peripheral nervous system. We have previously shown that macrophages substantially amplify neuropathic changes in various mouse models of CMT1 subforms and that targeting innate immune cells substantially ameliorates disease outcome. However, up to date, specific approaches targeting macrophages pharmacologically might entail side effects. Here, we investigate whether physical exercise dampens peripheral nerve inflammation in a model for an X-linked dominant form of CMT1 (CMT1X) and whether this improves neuropathological and clinical outcome subsequently. We found a moderate, but significant decline in the number of macrophages and an altered macrophage activation upon voluntary wheel running. These observations were accompanied by an improved clinical outcome and axonal preservation. Most interestingly, exercise restriction by ~40% accelerated amelioration of clinical outcome and further improved nerve structure by increasing myelin thickness compared to the unrestricted running group. This myelin-preserving effect of limited exercise was accompanied by an elevated expression of brain-derived neurotrophic factor (BDNF) in peripheral nerves, while the expression of other trophic factors like neuregulin-1, glial cell line-derived neurotrophic factor (GDNF) or insulin-like growth factor 1 (IGF-1) were not influenced by any mode of exercise. We demonstrate for the first time that exercise dampens inflammation and improves nerve structure in a mouse model for CMT1, likely leading to improved clinical outcome. Reducing the amount of exercise does not automatically decrease treatment efficacy, reflecting the need of optimally designed exercise studies to achieve safe and effective treatment options for CMT1 patients.

Abstract
Introduction: Charcot-Marie-Tooth disease (CMT) and related neuropathies represent the most prevalent inherited neuromuscular disorders. Nonetheless, there is still no pharmacological treatment available for any CMT type. However, the landscape is rapidly evolving and several novel approaches are providing encouraging results in preclinical studies and leading to clinical trials.Areas covered: The authors review the most promising therapies under study and the ongoing/planned clinical trials. Several approaches to address PMP22 overexpression underlying CMT1A, the most frequent subtype, are being tested. Gene silencing, targeting PMP22, and gene therapy, to introduce specific genes or to substitute or modulate defective ones, are being experimented in animal models. Compounds acting on ER stress, unfolded protein response, neuregulin pathways, phosphoinositides metabolism, axonal transport and degeneration, inflammation, polyol pathway, deoxysphingolipid metabolism, purine nucleotide pool are potential therapeutic candidates for different forms of CMT and related neuropathies.Expert opinion: We are getting closer to find effective therapies for CMT, but are far behind the exciting examples of other genetic neuromuscular disorders. The authors analyze the possible reasons for this gap and the way to fill it. Preclinical and clinical research is ongoing with coordinated efforts and they are confident that in the next few years we will see the first effective treatments.

Abstract
Background/aims High-intensity power training has been shown to be effective in improving muscular capabilities, functional performance and health-related quality of life in populations with physical impairments. However, the effectiveness of high-intensity power training in people with Charcot–Marie–Tooth disease remains uncertain. This case series investigated the effects of high-intensity power training on muscle performance, function and health-related quality of life in middle-aged women with Charcot-Marie-Tooth disease. Methods Four women (age 51–58 years) with Charcot–Marie–Tooth disease type 1A participated in 8 weeks of supervised high-intensity power training. Results All participants improved strength of the right hip abductors (46.7–109.7%) and left hip abductors (27.3–128.6%), maximal gait speed (2.3–9.1%), static balance (0.7–4.9%), tandem walk (−3.3 to −58.5%), and mental component scores on the Short Form 36 Health Status Survey (0.8–27.6%). Adherence to high-intensity power training was 100% and only one minor adverse event related to the intervention was reported. Conclusions Although promising, larger controlled studies are indicated to confirm the safety and efficacy of high-intensity progressive resistance and power training in this cohort.

Abstract
The foot-sole cutaneous receptors (section 2), their function in stance control (sway minimisation, exploratory role) (2.1), and the modulation of their effects by gait pattern and intended behaviour (2.2) are reviewed. Experimental manipulations (anaesthesia, temperature) (2.3 and 2.4) have shown that information from foot sole has widespread influence on balance. Foot-sole stimulation (2.5) appears to be a promising approach for rehabilitation. Proprioceptive information (3) has a pre-eminent role in balance and gait. Reflex responses to balance perturbations are produced by both leg and foot muscle stretch (3.1) and show complex interactions with skin input at both spinal and supra-spinal levels (3.2), where sensory feedback is modulated by posture, locomotion and vision. Other muscles, notably of neck and trunk, contribute to kinaesthesia and sense of orientation in space (3.3). The effects of age-related decline of afferent input are variable under different foot-contact and visual conditions (3.4). Muscle force diminishes with age and sarcopenia, affecting intrinsic foot muscles relaying relevant feedback (3.5). In neuropathy (4), reduction in cutaneous sensation accompanies the diminished density of viable receptors (4.1). Loss of foot-sole input goes along with large-fibre dysfunction in intrinsic foot muscles. Diabetic patients have an elevated risk of falling, and vision and vestibular compensation strategies may be inadequate (4.2). From Charcot-Marie-Tooth 1A disease (4.3) we have become aware of the role of spindle group II fibres and of the anatomical feet conditions in balance control. Lastly (5) we touch on the effects of nerve stimulation onto cortical and spinal excitability, which may participate in plasticity processes, and on exercise interventions to reduce the impact of neuropathy.

Phys Ther 2020; 101:6039324.

Abstract
OBJECTIVE Clear guidelines to prescribe aerobic exercise in neuromuscular diseases (NMD) are lacking, which hampers effective application in neuromuscular rehabilitation. This pilot study evaluated the feasibility and preliminary effectiveness of an individualized aerobic exercise program according to a recently developed training guide (B-FIT) to improve physical fitness in individuals with NMD. METHODS Thirty-one individuals who were ambulatory and had 15 different slowly progressive NMD participated in a 4-month, polarized, home-based, aerobic exercise program. The program included 2 low-intensity sessions and 1 high-intensity session per week. Feasibility outcomes were the following: completion rate, proportion of followed sessions, adverse events, and participant and therapist satisfaction based on a self-designed questionnaire. Submaximal incremental exercise tests were used to assess the effects on physical fitness. RESULTS Twenty-six participants (84%) completed the B-FIT program, and the proportion of followed sessions was >75%. Three adverse events were reported and resolved. Regarding satisfaction, participants (based on n = 9) reported feeling fitter, but training was considered insufficiently challenging. Physical therapists (n = 5) reported that B-FIT provides a clear, well-grounded guidance. They perceived the time investment for initiating the program and the carry-over to primary care as the main barriers. The mean (SD) submaximal heart rate (based on n = 20) reduced significantly by -6.5 beats per minute (95% CI = -11.8 to -1.2), from 121.7 (16.5) at baseline to 115.2 (14.3) after intervention. Submaximal ratings of perceived exertion, anaerobic threshold, and peak workload also improved significantly (P < .05). CONCLUSION The outcomes of this pilot study suggest that individualized aerobic exercise according to B-FIT is feasible and has potential to improve physical fitness in a wide variety of slowly progressive NMD. However, some barriers must be addressed before investigating the efficacy in a randomized controlled trial. IMPACT The outcomes of this study demonstrate the feasibility of individualized aerobic exercise according to the B-FIT training guide and the potential to improve physical fitness in NMD. Physical therapists indicated that the use of B-FIT provides a clear, well-grounded guidance. The training guide can support health care professionals in the application of aerobic exercise in adult neuromuscular rehabilitation. LAY SUMMARY Individualized exercise according to the B-FIT training guide is feasible in a wide variety of slowly progressive NMD and might help improve physical fitness.

Abstract
INTRODUCTION Charcot-Marie-Tooth (CMT) is the most common inherited polyneuropathy. Polyneuropathies are likely to affect the urogenital system. Urogenital dysfunction is rarely investigated and may be underestimated in CMT patients. AIM The aim of the present study was to perform a systematic review of the literature to collect all the available evidence on the presence of urogenital dysfunction and in patients with CMT. METHODS Data sources were MEDLINE, Pubmed, Scopus, and Google Scholar. All types of studies describing the presence of lower urinary tract dysfunction, erectile dysfunction (ED), anejaculation, and other sexual disorders in male patients with CMT were included. RESULTS Among 131 records identified, five articles were included in the qualitative synthesis. Lower urinary tract dysfunction, neurogenic bladder, ED, and other sexual dysfunctions have been reported in patients with CMT. One case of anejaculation has been described. CONCLUSION Urogenital dysfunction occurs in patients with CMT. Therefore, uro-andrologic counseling should be performed in the aging male with CMT. This might positively impact on his quality of life.

Abstract
BACKGROUND Physical activity is associated with positive health effects, but individuals with neuromuscular disease (NMD) may experience constraints being physically active. There is a gap in the literature on the activity level of people with NMDs, and therefore we did a study to determine the physical activity level in people with Limb-Girdle muscular dystrophy (LGMD) and Charcot-Marie-Tooth disease (CMT). METHODS This study used a cross-sectional design to obtain self-reported physical activity and sitting time among individuals with LGMD and CMT who were recruited from the Norwegian registry for hereditary and congenital neuromuscular diseases. RESULTS A total of 127 respondents who filled out questionnaires about either physical activity or sitting time were included in the analysis. Seventy (55.1%) had a diagnosis of CMT and 57 (44.9%) had a diagnosis of LGMD. Seventy-three (57.5%) respondents were female and 54 (42.5%) were male. Among the 108 respondents with available physical activity data, 44.4% reported being physically inactive. Among the 109 respondents with available sitting time data, the average sitting time was 8.6 h. Longer sitting time was associated with higher physical inactivity. CONCLUSION Among people with LGMD and CMT in our study, 55.6% reported being physically active. Respondents with LGMD and CMT reported longer sitting time and less physical activity compared with healthy respondents in other studies. Further research should explore variables and measures that can promote physical activity among people with neuromuscular conditions.

Abstract
Background and purpose Muscle‐strengthening, stretching or proprioceptive treatments may slow symptom progression in Charcot—Marie–Tooth (CMT) neuropathy. The aim of the study was to evaluate safety and efficacy of treadmill training in CMT1A. Methods We planned a multicenter, prospective, randomized, single‐blind, controlled study. We recruited 53 outpatients affected by CMT1A and randomized them into two treatment groups: one underwent stretching and proprioceptive exercise, whereas the other was additionally treated with treadmill training (TreSPE). Primary outcome measures (OMs) were the walking evaluations and secondary OM was the balance assessment. All participants were assessed at baseline and after 3 and 6 months of treatment. Results Most patients showed an improvement in at least one OM after 3 months [42/47 (89.4%)] and 6 months [38/40 (95%)] of treatment. No adverse events were reported in either group. Conclusions The most important finding was that both stretching and proprioceptive exercise and treadmill training had an objective benefit on patients affected by CMT disease, without causing overwork weakness. We had a low rate of drop out and did not find deterioration in motor performance. Our results also confirm that applying evidence‐based medicine methods to rehabilitative research is the correct way to test the efficacy of a treatment.

Abstract
INTRODUCTION Balance impairment contributes to gait dysfunction, falls, and reduced quality of life in adults with Charcot-Marie-Tooth disease (CMT) but has been minimally examined in pediatric CMT. METHODS The CMT Pediatric Scale (CMTPedS) was administered to 520 children with CMT. Associations between balance function (Bruininks-Oseretsky Test of Motor Proficiency [BOT-2]) and sensorimotor and gait impairments were investigated. RESULTS Daily trips/falls were reported by 42.3% of participants. Balance (BOT-2) varied by CMT subtype, was impaired in 42% of 4-year-olds, and declined with age (P < 0.001). Vibration (P < 0.001), pinprick (P < 0.004), ankle dorsiflexion strength (P < 0.001), and foot alignment (P < 0.004) were associated with BOT-2 balance (adjusted R2 = 0.28). The visual dependence of balance increased with age. DISCUSSION Balance impairment occurs from a young age in children with CMT. Balance intervention studies are required in pediatric CMT and should consider the degree of sensorimotor impairment, foot malalignment, and visual dependence. Muscle Nerve, 2019.

Abstract
OBJECTIVES We investigated the effectiveness of cycle ergometer training and resistance training to enhance the efficiency of standard care to improve walking ability, muscular strength of the lower limbs, cardiovascular endurance and health-related quality of life during inpatient rehabilitation in intensive care unit acquired weakness. MATERIALS & METHODS Thirty-nine patients with severe to moderate walking disability were enrolled in one of the three experimental groups: (a) ergometer training group, (b) resistance training group and (c) control group (standard care only). Intervention was applied 5 days a week over a 4-week period during inpatient neurological rehabilitation. We evaluated walking ability (Functional Ambulation Category test, timed up and go test, 10-metre walk test and 6-minute walk test), muscle strength (Medical Research Council and maximum muscle strength tests), cardiovascular endurance and muscular endurance of the lower limbs at the fatigue threshold (physical working capacity at fatigue threshold) and quality of life (medical outcomes study SF-36 form). All tests were performed at baseline, after two weeks of treatment and at the end of the 4-week intervention period. RESULTS Ergometer training and resistance training enhanced the effectiveness of standard care in order to improve (a) lower limb muscle strength, (b) walking ability and (c) cardiorespiratory fitness during inpatient rehabilitation of intensive care acquired weakness. In addition, ergometer training may be superior to resistance training. CONCLUSIONS Our data encourage more research to develop and implement these training tools in rehabilitation programmes for intensive care acquired weakness.

Abstract
BACKGROUND The outcome measures (OMs) in clinical trials for Charcot-Marie-Tooth disease (CMT) still represent an issue. A recent study highlighted that three additional clinical OMs, the 10-Meter Walk Test (10MWT), the 9-Hole Peg Test, and foot dorsal flexion dynamometry, further improve discrimination between severely and mildly affected patients. Another study has recently assessed the validity and reliability of the 6-Minute Walk Test (6MWT). AIM The aim of this study was to identify the most useful scales in the clinical evaluation of CMT1A patients. DESIGN Observational study of the baseline data collected in a multicenter, prospective, randomized, single blind, controlled study to evaluate the efficacy and safety of an innovative rehabilitation protocol based on treadmill training, stretching, respiratory, and proprioceptive exercises (TreSPE study) in CMT1A patients. SETTING The outpatient service of the four Italian centers involved, which are specialized in hereditary neuropathies. POPULATION Fifty-three subjects with a clinical and genetically confirmed diagnosis of CMT1A. METHODS At baseline, in addition to the CMT Neuropathy Score, all subjects underwent walking evaluation (6MWT, 10MWT), balance assessment (Berg Balance Scale [BBS], Short Physical Performance Battery [SPPB]) and a subjective evaluation of quality of life (SF36) and walking ability (Walk12). RESULTS Analyzing the baseline data, as expected, we found a strong correlation between walk and balance evaluation, proving the validity of these tests in investigating the functional impairment of CMT1A subjects. Particularly, we found that subjects with better balance control walk at higher speed and perceive less limitations in their physical activities or motor skills. This can be reconducted to the fact that ankle stability depends upon different factors such as anatomy integrity, muscle strength and proprioception. CONCLUSIONS We identify the 6MWT, 10MWT, and SPPB as the most useful scales, in addition to the CMTNS, to evaluate the functional impairment of CMT1A patients who retain their walking capability and we suggest the use of SPPB because of its rapidity to assess balance and gait disorders in clinical settings. CLINICAL REHABILITATION IMPACT In the clinical practice it is important to evaluate patients comprehensively but rapidly. These outcome measures can help us to correctly assess balance and walking ability in CMT1A patients.

Abstract
Pediatric neuromuscular diseases encompass all disorders with onset in childhood and where the primary area of pathology is in the peripheral nervous system. These conditions are largely genetic in etiology, and only those with a genetic underpinning will be presented in this review. This includes disorders of the anterior horn cell (e.g., spinal muscular atrophy), peripheral nerve (e.g., Charcot-Marie-Tooth disease), the neuromuscular junction (e.g., congenital myasthenic syndrome), and the muscle (myopathies and muscular dystrophies). Historically, pediatric neuromuscular disorders have uniformly been considered to be without treatment possibilities and to have dire prognoses. This perception has gradually changed, starting in part with the discovery and widespread application of corticosteroids for Duchenne muscular dystrophy. At present, several exciting therapeutic avenues are under investigation for a range of conditions, offering the potential for significant improvements in patient morbidities and mortality and, in some cases, curative intervention. In this review, we will present the current state of treatment for the most common pediatric neuromuscular conditions, and detail the treatment strategies with the greatest potential for helping with these devastating diseases.

Abstract
Many parents still hesitate to encourage their children to participate in resistance training programs. This is unfortunate since recent research shows that resistance training can positively affect children's health. This narrative review aims to present an overview of the health-associated effects resistance training can provide particularly in children and adolescents with disabilities by describing its effects on muscle strength, physical function, mental health, self-concept, obesity, and injury prevention. To illustrate the variety of possible fields of application, the effects of resistance training in children and adolescents suffering from Charcot-Marie-Tooth disease, cerebral palsy, Down syndrome, Ehlers-Danlos syndrome, joint hypermobility, juvenile idiopathic arthritis, obesity, and spina bifida are discussed. Although randomized controlled trials with a sufficiently large sample size are rare, the research presented in this review indicates that this mode of training might be a potent tool to improve mental and physical health by improving muscle strength, body composition, self-concept or functionality, reducing pain or injury risk, and strengthening bone or tendons even in the most vulnerable groups of children with physical or mental disability. Furthermore, it has to be emphasized that compared with other types of treatment resistance training is considered to be without adverse effects.

Abstract
Polyneuropathies are common neurologic disorders affecting the peripheral nerves. There are a number of causes of damage to these structures, such as genetic and metabolic factors, autoimmune disorders, infection, drug or environmental toxicity, and malignancy. Motor and sensory impairments are commonly encountered in these conditions, leading to altered balance and gait with increased risk of falling. Diabetic neuropathy is the most common cause of peripheral nerve disease and extensive investigation of balance and walking function revealed greater postural instability and delayed activation of distal muscles during walking. Although classically thought to be due to sensory impairment, it is now recognized that a motor contribution to balance and gait impairment cannot be ruled out in diabetic neuropathy. Inflammatory and inherited neuropathies have had less investigation. Variations in static and dynamic balance and depend on the sensory afferents affected and the degree of motor impairment. Motor impairment is a major contributor to alterations in gait pattern. Exercise is an effective rehabilitation approach that can improve muscle strength and postural responses. The gains can carry over into improved functional balance and walking. Orthotic interventions are also promising in supporting joints where there is significant muscle weakness, but newer devices are being developed that provide sensory feedback, e.g., vibration, which may be effective where sensory impairment is a key contributor to postural instability.

Abstract
Background Charcot-Marie-Tooth (CMT) disease is a hereditary neuropathy associated with impaired walking capacity. Some patients are too weak in the lower extremity muscles to walk at gravity with sufficient intensity or duration to gain benefit. Aim The aim was to investigate the effect of aerobic anti-gravity exercise in weak patients with CMT 1A and X. Methods Five adult patients performed moderate-intensity aerobic anti-gravity exercise 3/week for 10 weeks. Results There was a significant positive difference in Berg balance scale and postural stability test between test occasions, and walking distance in the 6-min walk test trended to increase. Conclusions The study indicates that the anti-gravity treadmill training of patients with CMT should be pursued in larger CMT cohorts.

Abstract
There have been few studies regarding physical training-induced peripheral nerve dysfunction in patients with hereditary neuropathy with liability to pressure palsies (HNPP), with the exception of soldiers that trained intensively. Here, we report a 15-year-old boy without family history of HNPP who developed bilateral painless brachial plexopathy following short-term barbell and plank training during a school baseball club activity. Muscle training-induced painless brachial plexopathy could be an initial symptom and may be underdiagnosed in adolescents with sporadic HNPP.

Abstract
BACKGROUND Preliminary studies have supported the utility of exercise as a treatment for Charcot-Marie-Tooth disease (CMT) patients. Despite being the most common inherited neuropathy, there remains a paucity of guidelines for CMT management. METHODS A retrospective chart review was performed on 297 CMT patients. Self-reported exercise and strength results from standardized dynamometer testing were obtained from adult patients' first visits. Values were converted and analyzed based on previously reported age- and sex-matched normative values. RESULTS Participants with CMT2 had greater strength values than those with CMT1 in hand grip, elbow flexion, and dorsiflexion (p<0.05). Participants with CMT1 and CMT2 who exercised were statistically significantly stronger in elbow flexion and dorsiflexion than those who did not exercise. CONCLUSIONS These preliminary results suggest that self-directed exercise is associated with greater strength in CMT patients of both CMT1 and CMT2 subtypes. Self-directed exercise may be a convenient, sustainable, and effective method of improving strength and decreasing disability in this population. Future research should explore the type of exercise prescription that best addresses the needs of the CMT population.

Abstract
BACKGROUND: Charcot-Marie-Tooth (CMT) disease is a hereditary disease with signs of chronic non-progressive motor-sensory neuropathy which is characterised by symmetric muscle atrophy and weakness of the distal portion of lower extremities. AIM: The aim is to present two cases with peroneal muscular atrophy, applied rehabilitation procedures and rehabilitation outcome. MATERIAL AND METHODS: Patient DR, aged 51, and patient KH, aged 78. Both patients had weakness and pronounced atrophy of the distal portion of lower extremities, numbness down the legs, contractures in the ankles and walking difficulties. Evaluation of patients included a clinical examination, Barthel Index, Time Up and Go test, measurement of the ankle range of motion, and a manual muscle test. On admission, the Barthel Index score was 60 in the first case, and 80 in the second. The rehabilitation program included exercise therapy with for lower extremity, occupational therapy, stationary bicycle riding, galvanic current, water exercises, and ankle-foot orthoses for both legs. RESULTS: The therapy applied had no significant changes in the clinical neurological status of the patients, but yet it provided some improvement in ankle contractures, better mobility, and a more stable gait. CONCLUSION: The application of rehabilitation procedures in patients with Charcot-Marie-Tooth disease can improve their functional status and walking stability.

Abstract
The paper reports a wheelchair-bound CMT 4A patient who became a Paralympic swimmer. She regularly performed intensive aerobic workout and competed in sprint distance events. She became a backstroke and freestyle gold medalist in the Italian Championships. Sport activity increased proximal muscle strength of upper limbs and improved QoL. Sport activity reduced anxiety, annulled depression and increased self-esteem and self-efficacy.
This study reports the positive physical, emotional and psychosocial changes induced by sport activity in a Paralympic swimmer with Charcot–Marie–Tooth (CMT) type 4A. When we compared evaluations before initiating sport activity with those after five years of competitive activity, we found: i) increased proximal muscles strength of upper limbs; ii) augmented ability to propel wheelchair independently; iii) improved quality of life; iv) reduced trait anxiety and striking improvement of depression; v) enhanced self-esteem. Longitudinal studies in large cohorts to evaluate the positive effects of sport activity are needed to support provision of evidence-based advice to patients and families.

Abstract
Compared to the central nervous system (CNS), peripheral nerves have a remarkable ability to regenerate and remyelinate. This regenerative capacity to a large extent is dependent on and supported by Schwann cells, the myelin-forming glial cells of the peripheral nervous system (PNS). In a variety of paradigms, Schwann cells are critical in the removal of the degenerated tissue, which is followed by remyelination of newly-regenerated axons. This unique plasticity of Schwann cells has been the target of myelin repair strategies in acute injuries and chronic diseases, such as hereditary demyelinating neuropathies. In one approach, the endogenous regenerative capacity of Schwann cells is enhanced through interventions such as exercise, electrical stimulation or pharmacological means. Alternatively, Schwann cells derived from healthy nerves, or engineered from different tissue sources have been transplanted into the PNS to support remyelination. These transplant approaches can then be further enhanced by exercise and/or electrical stimulation, as well as by the inclusion of biomaterial engineered to support glial cell viability and neurite extension. Advances in our basic understanding of peripheral nerve biology, as well as biomaterial engineering, will further improve the functional repair of myelinated peripheral nerves.
