Respiratory Telerehabilitation of Boys and Young Men with Duchenne Muscular Dystrophy in the COVID-19 Pandemic

Maintaining Physical Health in Individuals with Duchenne Muscular Dystrophy Through Telerehabilitation

AIMS

To investigate the effects of a telerehabilitation program on walking performance, lower and upper extremity function, fall frequency, respiratory function, and satisfaction in individuals with Duchenne muscular dystrophy (DMD).

METHODS

Thirty children (mean age 8.8 ± 4.2 years) were ambulant (Group 1), and 12 youth (18.5 ± 4.7 years) were non-ambulant (Group 2). The telerehabilitation program was applied by physiotherapists for 24 sessions (3 days/week). The 10-meter walking test, stand up from the supine position test, the modified upper extremity performance test, repetition of Lower and upper extremity movements, and the single breath count (SBC) test were administered. Fall frequency and satisfaction level were also recorded.

RESULTS

Significant improvement was found after telerehabilitation in upper extremity performance, repetition of lower and upper extremity movements, fall frequency, and SBC scores in Group 1. Changes in the 10-minute Walk and Stand Up from the Supine Position tests were not significant. There was a significant improvement in SBC scores in Group 2. Satisfaction with the service was 88%.

CONCLUSIONS

The 8-week telerehabilitation program was effective in improving aspects of upper and lower extremity function, fall frequency, pulmonary function, and satisfaction levels in individuals with DMD.

Chest Physiotherapy Interventions for Children During SARS-COV-2 Pandemic

Since the first case of Severe Acute Respiratory Syndrome Coronavirus-2/Coronavirus Disease 2019 (SARS-COV-2/COVID-19) was discovered in Wuhan, China, it spread to vast limits globally and became a public health disaster, affecting nearly all countries around the globe. Along with mainstream medical treatment, alternative medicine desperately was the need of the hour for youngsters to manage their symptoms while being self-quarantined and ultimately to improve their chances of survival and recovery from COVID-19. Since the beginning of SARS-COV-2, few studies address the clinical-functional presentation of viral infection and management with physiotherapy for children. Major online electronic databases PubMed, PEDro, and Google Scholar were researched to identify, organize and commission the current review. To create a search strategy, Medical Subject Headings and Descriptors of Science and Health were utilized. The authors looked for other studies by screening the references list of the potentially pertinent papers. These computerized searches turned up studies and those studies' bibliographies with pertinent citations were examined. Personal protective equipment was a crucial component for protection and contact precaution. Following hypoxia, effective oxygen therapy is administered right away. When necessary, under the right circumstances, nasal high-flow oxygen therapy, non-invasive ventilation, lung-protective breathing methods, and prone positioning can be used. Children with SARS-CoV-2/COVID-19 may benefit from physiotherapy interventions with a focus on ventilatory management, airway clearance procedures, early activities, and mobilization.

A pilot study of an integrated, personalized, respiratory and motor telerehabilitation program for pediatric patients with hereditary neuromuscular disorders

INTRODUCTION

Telerehabilitation provides physical training to patients through telecommunication networks. We examined the feasibility, safety, and efficacy of an integrated, personalized, respiratory and motor telerehabilitation program for pediatric patients with hereditary neuromuscular disorders (NMDs).

METHODS

Stable pediatric patients were recruited for a 16-week home training program with personalized pulmonary, upper and lower limb exercises. Patients reviewed instructional videos at home and attended bi-weekly follow-ups through video or audio calls, text messages, or emails. The primary outcomes were respiratory function, Medical Research Council (MRC) grading, hand/pinch strength, 6-minute walk test, and Pediatric Quality-of-Life Inventory 3.0 Neuromuscular Module survey. The secondary outcomes were study compliance and user feedback.

RESULTS

Patients with spinal muscular atrophy (n = 4), congenital myasthenic syndrome (n = 2), and Duchenne muscular dystrophy (n = 2) completed the program. The median weekly exercise time was 101.3 min (range: 30.0-266.9). No extra face-to-face physiotherapy sessions were requested by the patients. No adverse events were reported. After the study, patients showed improvements in maximal expiratory pressure (35.0 vs. 47.5 cm H2O, p = .028) and maintained their MRC grade, hand/pinch strength, and walking distance. Patients also reported improvements in the Pediatric Quality-of-Life Inventory 3.0 Neuromuscular Module survey score (74.5 vs. 87.0, p = .036). Patients rated the overall program highly (mean: 4.00/5.00) and recommended it as a standard of care (mean: 4.38/5.00).

DISCUSSION

Our telerehabilitation program was feasible, safe, and possibly effective for this pilot cohort of stable pediatric patients with hereditary NMDs. Larger-scale studies for longer periods are warranted to confirm the results.

Telehealth-based exercise in amyotrophic lateral sclerosis

The Veterans Health Administration (VHA) has served as a leader in the implementation of telerehabilitation technologies and continues to expand utilization of non-traditional patient encounters to better serve a geographically and demographically diverse population. Amyotrophic Lateral Sclerosis (ALS) is a progressive neurodegenerative disease impacting Veterans at a higher rate than the civilian population and associated with high levels of disability and limited access to subspecialized care. There is growing evidence supporting exercise-based interventions as an independent or adjunctive treatment to maintain or restore function for this patient population; many of these interventions can be delivered remotely by telehealth. The recent advancements in disease-modifying therapies for neuromuscular disorders will likely increase the importance of rehabilitation interventions to maximize functional outcomes. Here, we review the evidence for specific exercise interventions in ALS and the evidence for telehealth-based exercise in neuromuscular disorders. We then use this existing literature to propose a framework for telehealth delivery of these treatments, including feasible exercise interventions and remote outcome measures, recommended peripheral devices, and an example of a current remote group exercise program offered through VHA.

A Virtual Reality Exergame: Clinician-Guided Breathing and Relaxation for Children with Muscular Dystrophy

This study introduces a VR-based breathing and relaxation exergame tailored for individuals with Duchenne muscular dystrophy (DMD). DMD is a rare neuromuscular disease that leads to respiratory muscle dysfunction with anxiety being a common comorbidity. Clinical management requires frequent visits to rare disease specialists to manage symptom progression. Limited availability and/or proximity of rare disease experts present challenges to care and can lead to missed care opportunities and reduced quality of life. We propose a breathing and relaxation exergame with remote telehealth applicability that incorporates shared patient-clinician VR interaction, and physiological sensors that provide both real-time feedback to the patient and health analytics for the clinician. The game focuses on two key aspects of DMD clinical care that can be mediated through control of breathing: relaxation/mindfulness training and respiratory muscle exercise. The system was evaluated among 13 individuals, including 4 participants with DMD. Feedback surveys, interviews, and focus group discussions with participants, accompanying family members, and clinicians demonstrated the feasibility of this VR tool for telehealth or as part of a home exercise program.

The Association between the Respiratory System and Upper Limb Strength in Males with Duchenne Muscular Dystrophy: A New Field for Intervention?

Progressive, irreversible muscle weakness is the leading symptom of Duchenne muscular dystrophy (DMD), often resulting in death from respiratory muscle failure. Little is known about the relationship between the functioning of the respiratory system and the hand grip-a function which remains long preserved. This study aimed to investigate the interdependence between muscle strength and the function of both hand grip and the respiratory system in patients with DMD.

MATERIALS AND METHOD

The study included cohort patients, aged 6-17, with DMD, recruited from the Rare Disease Centre, Gdansk, Poland. Clinical status (Vignos scale, Brook scale), pulmonary function (respiratory muscle strength-MIP, MEP); spirometry (FEV1; FVC), as well as upper limb function (performance of the upper limb-PUL 2.0) and hand grip strength (HGS) (hand-held dynamometer) were evaluated in all participants.

RESULTS

Finally, 53 boys (mean age 11.41 ± 3.70 years, 25 non-ambulant) were included. Each of the participants presented a lower %pv of MIP (48.11 ± 27), MEP (38.11 ± 22), PUL (75.64 ± 27), and HGS (33.28 ± 18). There were differences between the ambulatory and non-ambulatory groups in values of MIP, MEP, FVC, PUL, HGS (p < 0.001 for all), and FEV1 (p < 0.013). There were correlations between PUL, HGS, and MIP (R = 0.56; R = 0.61, p < 0.001 both), MEP (R = 0.59; R = 0.62, p < 0.001), FVC (R = 0.77; R = 0.77, p < 0.001), and FEV1 (R = 0.77; R = 0.79; p < 0.001). These correlations were found for all participants, but non-ambulatory patients presented stronger relationships.

CONCLUSIONS

1. The pulmonary and upper limb functions were within the normal range in ambulatory and low in non-ambulatory patients with DMD, but the muscle strength of both systems was low, regardless of the stage of the disease. 2. There seems to be an interdependence between the respiratory system and upper limb strength in terms of muscle strength and function in DMD patients, which is stronger in non-ambulatory patients. This may be the basis for the creation of a new personalized plan in rehabilitation-the simultaneous rehabilitation of the respiratory and upper limb muscles. Further studies on this theory should be conducted.

The Refinement of Home Exercise Program for Children and Adolescents With Muscular Dystrophy in the Present COVID-19 Pandemic Scenario: A Scoping Review

Muscular dystrophies (MDs) are a category of hereditary illnesses characterized by the gradual malfunction and/or weakening of the skeletal muscles. This disease of the muscles also results in hypotonia and joint contracture, along with raised serum creatine kinase (CK) levels. To prevent complications, continuous physiotherapy is advised for children with muscular dystrophy, which is even asked to perform at home as a home exercise program (HEP). As a result, the home exercise program (HEP) is critical in maintaining the optimal health of children with Duchenne muscular dystrophy (DMD). The present coronavirus (COVID-19) pandemic has adversely affected these children as there was very little scope to get direct help from a physiotherapist. Meanwhile, the home program was continued by many to compensate for the direct benefit. However, because of the lack of specific guidelines and structured methodology to follow for a home program, there was a deterioration in the health status of many children. There is a need to understand how the children are getting affected and the way the home program can be refined to help needy children with muscular dystrophy. Our scoping review aims to identify the present home program patterns being followed for children with DMD and their scope for refinement. The data were collected from electronic databases including PubMed, ProQuest, Cochrane, and Web of Science. We searched four electronic databases until September 2021. We included the published case studies, observational and experimental studies that described the positive impact of home exercise programs, and the methodology they followed as an alternative to institution-based physiotherapy. One hundred thirty-eight titles were screened, and 58 met the inclusion criteria. Along with regular physiotherapy, the incorporation of HEP helped in early complication prevention in patients with muscular dystrophy. The HEP was found to be a successful adjunct in the COVID-19 scenario. This review presents different therapeutic measures that can be taken for the prevention of complications in patients with MD and how the HEP plays an important role in removing the gaps on how HEP is beneficial in the COVID-19 scenario and a scope to refine the present methodologies for more accurate management.

Comparison of telerehabilitation versus home-based video exercise in patients with Duchenne muscular dystrophy: a single-blind randomized study

Introduction

Patients with Duchenne muscular dystrophy (DMD) have lost their access to on-site rehabilitation due to the COVID-19 pandemic. Telerehabilitation can be a viable approach for these patients to protect their muscle strength and functional status. The aim of this study is to compare telerehabilitation with home-based video exercises.

Patients and methods

Male, ambulatory DMD patients were randomized into telerehabilitation and video-exercise groups. Nineteen patients were included in the final analyses. Telerehabilitation consisted of live online exercises, while video exercise implemented a pre-recorded video as a home-based program. Both programs spanned 8 weeks, three times a week. Patients’ muscle strength with a hand-held dynamometer, Quick Motor Function Test, North-Star Ambulatory Assessment (NSAA), 6-Minute Walk Test (6MWT) and Caregiver Burden were recorded before and after treatment.

Results

The 6MWT of the telerehabilitation group was391.26 ± 95.08 m before and387.75 ± 210.93 after treatment (p = 0.94) and 327.46 ± 103.88 m before treatment and313.77 ± 114.55 after treatment in video group (p = 0.63). The mean NSAA score of the telerehabilitation group were26.70 ± 8.04 before treatment and 25.20 ± 11.33 after treatment (p = 0.24). In the video group scores were 21.66 ± 6.65 before to 22.00 ± 8.61 after treatment (p = 0.87). There were no significant changes between groups at the end of the treatments. The telerehabilitation group's neck extension, bilateral shoulder abduction, and left shoulder flexion, bilateral knee flexion and extension, bilateral ankle dorsiflexion, and left ankle plantar flexion strength improved significantly and were better than the video group (p < 0.05 for all measurements).

Conclusion

A telerehabilitation approach is superior in improving muscle strength than a video-based home exercise, but none of the programs improved functional outcomes in ambulatory patients with DMD.

A Comprehensive Review of Neuromuscular Manifestations of COVID-19 and Management of Pre-Existing Neuromuscular Disorders in Children

Since the emergence of SARS-CoV-2, several studies have been published describing neuromuscular manifestations of the disease, as well as management of pre-existing pediatric neuromuscular disorders during the COVID-19 pandemic. These disorders include muscular dystrophies, myasthenic syndromes, peripheral nerve disorders, and spinal muscular atrophy. Such patients are a vulnerable population due to frequent complications such as scoliosis, cardiomyopathy, and restrictive lung disease that put them at risk of severe complications of COVID-19. In this review, neuromuscular manifestations of COVID-19 in children and the management of pre-existing pediatric neuromuscular disorders during the COVID-19 pandemic are discussed. We also review strategies to alleviate pandemic-associated disruptions in clinical care and research, including the emerging role of telemedicine and telerehabilitation to address the continued special needs of these patients.

Benefits of Telemonitoring of Pulmonary Function—3-Month Follow-Up of Home Electronic Spirometry in Patients with Duchenne Muscular Dystrophy

Background: In patients with Duchenne Muscular Dystrophy (DMD), the respiratory system determines the quality and length of life; therefore, the search for easy and safe everyday monitoring of the pulmonary function is currently extremely important, particularly in the COVID-19 pandemic. The aim of the study was to evaluate the influence of a three-month home electronic spirometry (e-spirometry) monitoring of the pulmonary function and strength of respiratory muscles as well as the patients’ benefits from this telemetric program. Methods: Twenty-one boys with DMD (aged 7–22; non-ambulatory-11) received a remote electronic spirometer for home use with a special application dedicated for patients and connected with a doctor platform. Control of the hospital spirometry (forced vital capacity-FVC, forced expiratory volume in 1 second-FEV1, peak expiratory flow-PEF) and respiratory muscle strength (maximal inspiratory-MIP and expiratory pressures-MEP) before and after the three-month monitoring were performed as well telemonitoring benefit survey. Results: A total of 1403 measurements were performed; 15 of the participants were able to achieve correct attempts. There were no differences between the hospital and the home spirometry results as well as between respiratory muscle strength during v1 vs. v2 visits for the whole study group (all parameters p > 0.05); the six participants achieved increased value of FVC during the study period. There was a positive correlation between ΔFVC and the number of assessments during the home spirometry (r = 0.7, p < 0.001). Differences between FVC and MIP_cmH2O (r = 0.58; p = 0.01), MEP_cmH2O (r = 0.75; p < 0.001) was revealed. The mean general satisfaction rating of the telemonitoring was 4.46/5 (SD 0.66) after one month and 4.91/5 (SD 0.28) after three months. The most reported benefit of the home monitoring was the improvement in breathing (38% of participants after one month, 52% after three months of telemonitoring). Forgetting about the procedures was the most common reason for irregular measurements; the participants reported also increased motivation but less time to perform tests. Conclusions: The study indicates high compliance of the home telemonitoring results with the examination in the hospital. Benefits from home spirometry were visible for all participants; the most important benefit was breathing improvement. The remote home spirometry is usable for everyday monitoring of the pulmonary function in DMD patients as well can be also treated as respiratory muscle training.

COVID-19 and neurologic manifestations: a synthesis from the child neurologist's corner

BACKGROUND

Since December 2019, the SARS-CoV-2 virus has been a global health issue. The main clinical presentation of this virus is a flu-like disease; however, patients with diverse neurologic manifestations have also been reported. In this review, we attempt to summarize, discuss and update the knowledge of the neurologic manifestations in the pediatric population affected by SARS-CoV-2 infection and the pandemic's effects in children with neurologic diseases.

DATA SOURCES

This review analyzes studies found on the PubMed database using the following keywords: Neurologic manifestations COVID-19, Neurological COVID-19, coronavirus, SARS-CoV-2, pediatric COVID-19, COVID-19 in children, MIS-C, Pediatric Inflammatory Multisystem Syndrome, Guillain Barré Syndrome, Stroke, ADEM, and Anti-NMDA encephalitis. All studies cited were published between 2004 and 2022, and represent the most relevant articles in the field. The World Health Organization COVID-19 online dashboard was assessed to obtain updated epidemiological data.

RESULTS

The most common neurologic symptoms in the pediatric population are headache, seizures, encephalopathy, and muscle weakness. These can be present during COVID-19 or weeks after recovering from it. Children who presented with multi-system inflammatory syndrome had a higher incidence of neurologic manifestations, which conferred a greater risk of morbidity and mortality. Several neuro-pathophysiological mechanisms have been proposed, including direct virus invasion, hyper-inflammatory reactions, multi-systemic failure, prothrombotic states, and immune-mediated processes. On the other hand, the COVID-19 pandemic has affected patients with neurologic diseases, making it challenging to access controls, treatment, and therapies.

CONCLUSIONS

Various neurologic manifestations have been associated with children's SARS-CoV-2 infection. It is important to identify and give them proper and opportune treatment because they can be potentially grave and life-threatening; some can lead to long-lasting sequelae. Different neuro-pathophysiological mechanisms have been proposed, however, a causal relationship between SARS-CoV-2 infection and neurologic manifestations remains to be proven. Patients with neurologic diseases are especially affected by COVID-19, not only by the disease itself but also by its complications and pandemic management measures.

Morbidity, Clinical Course and Vaccination against SARS-CoV-2 Virus in Patients with Duchenne Muscular Dystrophy: A Patient Reported Survey

Background: Patients with Duchenne muscular dystrophy (DMD) may be at higher risk of a severe course of COVID-19. The aim of the study was to evaluate: (1) the incidence and course of COVID-19 infection in DMD patients; (2) the vaccination status of DMD patients; and (3) COVID-19 related anxiety among DMD families. Materials and Methods: The study was conducted during an online symposium for DMD patients and their families. All participants (DMD families; n = 150) were asked to fill in the online survey with questions about COVID-19 infection history, vaccination against SARS-CoV-2 and anxiety during pandemic. Results: 53 DMD patients filled in the survey. Five (9.43%) were COVID-19 positive with mild symptoms of respiratory infection and anosmia; 23 (42.6%) were vaccinated, but in almost 20% of DMD families, none of the family members was vaccinated. Respondents revealed anxiety related both to the vaccination procedure and to COVID-19 infection (complications after infection 93.6%, death 62.4% respondents). Changes in health care system organization also aroused concern among participants (85.3%). Conclusion: The course of the COVID-19 infection in DMD patients was mild. Not enough patients with DMD and their families are vaccinated. Education about the management of COVID-19 infections and the vaccination procedure for DMD patients is needed and expected.

Effectiveness and Acceptability of Telerehabilitation in Physical Therapy during COVID-19 in Children: Findings of a Systematic Review

The goal of this systematic review was to determine the efficacy and acceptability of telerehabilitation in physical therapy (PT) and parental acceptance during the COVID-19 pandemic in children. In 2021, an electronic search of academic articles was performed using databases such as Embase, PubMed and Scopus. One-hundred and one articles did not satisfy the eligibility criteria after deleting duplicates and reviewing abstracts, while 16 papers did not meet eligibility after reviewing complete texts. Hence, full texts for 13 articles were retrieved, which were incorporated in the review. All these studies were observational studies assessing the effectiveness and acceptability of telerehabilitation in PT required for diverse conditions in children during the COVID-19 pandemic. All included studies revealed a positive effect of telerehabilitation in PT during the COVID-19 pandemic in children with different conditions. Moreover, the included studies revealed that both rehabilitation professionals and parents or caregivers of children were satisfied with the telerehabilitation services provided remotely. Thus, telerehabilitation appears to be a suitable and convenient strategy to offer remote services to children in need but cannot visit in person due to COVID-19. The existing evidence shows that telerehabilitation can be considered effective for children who need PT for any health condition mainly during the pandemic. However, due to the dearth of studies in this area, exploring this topic is recommended mostly in low-middle-income countries with poor access to health care services and limited resources.

Is It Possible to Have Home E-Monitoring of Pulmonary Function in Our Patients with Duchenne Muscular Dystrophy in the COVID-19 Pandemic?-A One Center Pilot Study

Background: Duchenne muscular dystrophy (DMD) is the most common, progressive, irreversible muscular dystrophy. Pulmonary function is crucial for duration of life in this disease. Currently, the European Respiratory Society is focused on digital health, seeking innovations that will be realistic for digital respiratory medicine to support professionals and patients during the COVID-19 pandemic. Aims: The aim of this study was to investigate whether it is possible to monitor pulmonary function at home using an individual electronic spirometry system in boys with Duchenne muscular dystrophy. Materials and methods: In this observational, prospective study, conducted from March 2021 to June 2021, twenty boys with DMD (aged 8–16) were enrolled. The patients were recruited from the Rare Disease Centre, University Clinical Centre, of Gdańsk, Poland. Medical history and anthropometric data were collected, and spirometry (Jaeger, Germany) was performed in all patients at the start of the study. Each patient received an electronic individual spirometer (AioCare) and was asked to perform spirometry on their own every day, morning and evening, at home for a period of 4 weeks. The number of measurements, correctness of performing measurements, forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1), and peak expiratory flow (PEF) were evaluated. Results: Finally, 14 out of 20 boys enrolled in the study with a mean age of 12.5 years (7 non-ambulatory) applied and received a home spirometer (AioCare). A total of 283 measurements were performed by all patients at home for 4 weeks. Half of the patients were able to perform measurements correctly. There were no significant differences between mean values of FVC, FE1, PEF between home and hospital spirometry (p > 0.05) expect PEF pv% (p < 0.00046). Patients with higher FEV1 (p = 0.0387) and lower BMI (p = 0.0494) were more likely to take home spirometer measurements. The mean general satisfaction rating of home-spirometry was 4.33/5 (SD 0.78), the mean intelligibility rating was 4.83/5 (SD 0.58). Reasons for irregular measurements were: forgetting (43%), lack of motivation (29%), difficulty (14%), lack of time (14%). Conclusion: Home electronic monitoring of pulmonary function in patients with DMD is possible to implement in daily routines at home. This protocol should be introduced as early as possible in patients 7–8 years old with good, preserved lung function. Patients accept this form of medical care but require more education about the benefits of e-monitoring. There is a need to implement a system to remind patients of the use of electronic medical devices at home, e.g., via SMS (short message service).
