Abstract :

Hemiplegic cerebral palsy (HCP) is a common ‎neurophysiological condition in children, primarily causing ‎motor impairments in the upper extremities. This study ‎investigated the effectiveness of a novel multimodal ‎rehabilitation protocol, which combined computer-based ‎games and mechanoreceptor stimulation of the affected ‎forearm, for improving motor function in children with HCP. ‎Four children (ages 7–9) participated in 10 half-hour sessions. ‎Clinical motor function of the upper extremity was measured ‎using the Fugl-Meyer Assessment (FMA-UE) before and after ‎the intervention. Hand joint kinematics, including the angles ‎of the shoulder, arm, and wrist of the affected hand, were also ‎recorded during these rehabilitation tasks. To quantify ‎changes, advanced analytical tools such as Detrended ‎Fluctuation Analysis (DFA) and Power Spectrum Density ‎‎(PSD) were employed to assess motor stability and inter-joint ‎coordination. The results showed significant clinical ‎improvement in FMA scores which indicates motor ‎enhancement. The kinematic analysis confirmed these clinical ‎findings provided critical new insights into the underlying ‎quality of movement, highlighting the efficacy of this approach ‎in promoting motor recovery. In conclusion, this multimodal ‎protocol is an effective approach to improve motor recovery in ‎children with cerebral palsy. This study also confirms the ‎necessity of advanced analytical tools and a personalized ‎medicine model to optimize patient outcomes. ‎
