Efficacy of Physical Fitness Training Combined With Exercise Therapy on Gait in Children With Cerebral Palsy

This observational study is designed to investigate the time-dynamic characteristics of gait variability in children with spastic cerebral palsy (SCP). A total of 36 children with SCP and 36 age-, sex-, and BMI-matched typically developing children are recruited from the Children's Rehabilitation Center of the Affiliated Hospital of Binzhou Medical University. Using a portable gait analysis system (IDEEA, Minisun, USA) and a wireless surface electromyography system (Delsys, USA), participants perform a 3-minute continuous walking test at a self-selected comfortable speed. Key spatiotemporal gait parameters and electromyographic root mean square (RMS) values of the tibialis anterior and gastrocnemius muscles are assessed at predefined time points (10 seconds, 1 minute, 2 minutes, and 3 minutes). This study aims to examine temporal changes in gait variability and muscle activation during continuous walking in children with SCP, with the objective of identifying potential time points that may inform the optimization of walking-rest intervals in rehabilitation training.
