Summary

This randomized clinical research will assess the impact of a Pediatric Endurance and Limb Strengthening (PEDAL) program, both with and without Electrical Muscle Stimulation (EMS), on balance, gait, and mobility in children diagnosed with cerebral palsy. A total of 26 individuals will be recruited via purposive sampling and randomly allocated to two groups utilizing the sealed envelope method. Group A will undergo the PEDAL program in conjunction with electrical muscle stimulation (EMS) administered to the quadriceps during stationary cycling, whereas Group B will participate in the PEDAL program exclusively, without EMS. Both groups will participate in supervised sessions three times weekly for four weeks, with each session lasting 60 minutes and comprising a warm-up, cycling-based strength and endurance training, and cool-down stretches. EMS parameters will be implemented in accordance with published protocols for strength (30-80 Hz, 150-350 μs) and endurance (8-35 Hz, 150-250 μs) training. Outcome measures, comprising the Berg Balance Scale, Timed Up and Go Test, and Gait Outcomes Assessment List (GOAL™️) questionnaire, will be evaluated at baseline and following four weeks of intervention. The data will be examined utilizing SPSS version 27. This study aims to determine whether incorporating EMS into a structured pediatric strengthening and endurance regimen yields greater improvements in motor function compared to exercise alone.

Detailed description

Cerebral palsy (CP) is a predominant cause of childhood impairment, characterized by diminished strength, decreased endurance, inadequate postural control, and restrictions in movement and mobility. Rehabilitation regimens emphasizing endurance and limb strengthening have demonstrated beneficial impacts on motor performance and functional independence in this demographic. Nonetheless, voluntary muscular activation in children with cerebral palsy is frequently constrained, potentially diminishing the efficacy of traditional exercise regimens. Electrical muscle stimulation (EMS) has been implemented as a supplementary method to augment muscle recruitment, reduce stiffness, and enhance neuromuscular control. This trial will examine the Pediatric Endurance and Limb Strengthening (PEDAL) program, both with and without Electrical Muscle Stimulation (EMS), in children diagnosed with cerebral palsy. The PEDAL program employs cycling-based training aimed at enhancing aerobic endurance and lower-limb strength, integrating increasing resistance and functional task elements. In the intervention group, electrical muscle stimulation (EMS) will be administered to the quadriceps muscles during exercise to enhance contractions and potentially increase the training benefits. The study aims to determine if the integration of EMS with endurance and strength training yields superior enhancements in balance, gait, and mobility compared to exercise alone. This project aims to enhance the evidence foundation for pediatric neurorehabilitation, perhaps facilitating the incorporation of EMS-assisted exercise into standard physiotherapy for children with cerebral palsy to optimize motor results and independence.

Interventions

Type	Name	Description
DEVICE	PEDAL Program with Electrical Muscle Stimulation	Electrical Muscle Stimulation (EMS) will be applied to the quadriceps muscles of children with cerebral palsy during stationary cycling sessions as part of the Pediatric Endurance and Limb Strengthening (PEDAL) program. EMS will be delivered using clinically approved portable stimulators at parameters appropriate for muscle strengthening and endurance training (frequency 35-50 Hz, pulse width 200-400 μs, duty cycle on/off as tolerated). EMS will be administered simultaneously with cycling to enhance muscle activation and improve motor outcome
BEHAVIORAL	PEDAL Program without Electrical Muscle Stimulation	The PEDAL program is a structured exercise intervention designed for children with cerebral palsy. It includes 60-minute sessions of stationary cycling, warm-up, endurance and limb strengthening exercises, and cool-down stretching. Sessions are conducted three times per week for four weeks under therapist supervision. This program is used in both arms of the trial, with or without adjunct Electrical Muscle Stimulation (EMS).
