Telehealth-Supervised Resistance Training for Children With Cerebral Palsy

Overview

The goal of this clinical trial is to evaluate the feasibility and potential benefits of telehealth-supervised resistance training in ambulatory children aged 6 to 15 years with cerebral palsy (CP) classified as Gross Motor Function Classification System (GMFCS) levels I-III. The main questions it aims to answer are: * Is a 12-week telehealth-delivered resistance training program feasible and acceptable for children with CP and their caregivers? * Can the program improve physical function and psychosocial well-being in this population? Participants will: * Take part in three 40-minute, live-streamed resistance training sessions each week for 12 weeks, using elastic bands, sandbag weights, and balance tools * Complete physical assessments before and after the program, including the 1-minute walk test, 10-meter walk test, 30-second sit-to-stand test, and Pediatric Balance Scale * Complete quality of life surveys using the Pediatric Quality of Life Inventory (PedsQL™ 3.0 CP Module) * Have caregivers complete a custom questionnaire about the cost and acceptability of the program

Cerebral palsy (CP) is a lifelong neurodevelopmental disorder caused by non-progressive disturbances in the developing fetal or infant brain. It is characterized by impairments in movement and posture, often accompanied by disturbances in sensation, perception, cognition, communication, and behavior. Globally, CP affects an estimated 17 million individuals, with a birth prevalence of approximately 2 to 2.5 per 1,000 live births . In China, more than 6 million children are estimated to be living with CP, and approximately 40,000 new cases occur each year. Motor impairments in CP often lead to compromised gross motor function, altered gait mechanics, and reduced muscle force generation. These deficits significantly impact daily living activities, including walking, stair climbing, and performing transitions such as standing from a seated position. Muscle weakness, in particular, is a primary contributor to poor mobility and reduced participation in community and educational settings. Children with Gross Motor Function Classification System (GMFCS) levels I-III are ambulatory but may still experience fatigue, slow gait speed, or difficulty in navigating uneven terrain. Resistance training has gained empirical support as an effective intervention for improving muscle strength, joint stability, and gross motor function in children with mild CP. As highlighted in our recent meta-analysis, a growing body of evidence from randomized controlled trials indicates that well-structured, progressive resistance training programs lead to measurable improvements in lower-limb muscle morphology, which is directly related to strength, walking performance, and motor control. Ultimately, these muscle adaptations are closely linked to gains in functional independence, including stair climbing, transitions, and longer walking endurance - activities essential for participation in home, school, and recreational settings. Despite its proven efficacy, access to therapist-supervised or facility-based resistance training remains limited for many families - particularly those living in low-resource or rural settings. Children with CP are disproportionately represented among lower-income households, and socioeconomic factors can severely limit access to regular rehabilitation services. Out-of-pocket expenses for transportation, time off work for caregivers, and session fees create significant burdens, contributing to inadequate adherence and suboptimal rehabilitation outcomes. Telehealth has emerged as a promising strategy to overcome these barriers by delivering structured, therapist-guided interventions remotely. The expansion of digital health technologies, particularly during the COVID-19 pandemic, has accelerated the adoption of tele-rehabilitation for various clinical populations. Live-streamed and app-based exercise training programs have shown promise in able-bodied populations due to their low cost, flexibility, and minimal infrastructure requirements. For children with CP, a telehealth model may increase access and engagement while reducing logistical and financial strain on families. To our knowledge, no published studies have systematically evaluated the effects of telehealth-supervised resistance training specifically targeting improvements in functional capacity among children with CP. Given the affordability of this model - tele-exercise classes may cost as little as 10 CNY per session, and home exercise kits can be assembled using low-cost elastic bands and resistance tools - this approach may provide a viable, family-centered solution. The model is particularly attractive in the context of China and other low- and middle-income countries, where rehabilitation access is highly variable and often concentrated in urban centers. The present study aims to evaluate the feasibility and efficacy of a telehealth-supervised resistance training program targeting lower-limb muscle strength and functional capacity in children with mild CP. This single-arm intervention trial will examine changes in gross motor ability, lower-limb muscle function, and parent-reported outcomes following a 3-month remotely supervised exercise protocol. The findings will provide initial evidence to inform the scalability and cost-effectiveness of telehealth-based rehabilitation models and may offer an inclusive and sustainable approach for pediatric rehabilitation in socioeconomically disadvantaged settings.
