BACKGROUND: Cerebral palsy (CP) is a neurodevelopmental disorder characterized by spasticity, which significantly impairs motor function. Traditional treatments offer limited relief and carry risks. Repetitive peripheral magnetic stimulation (rPMS) presents a promising non-invasive alternative. This study aimed to evaluate the efficacy of rPMS in managing triceps surae spasticity in children with CP and to identify factors influencing its effectiveness.
METHODS: A retrospective cohort study was conducted with 271 children aged 6-12 years with CP (GMFCS levels I-II). Participants were assigned to conventional treatment (n = 131) or rPMS (n = 140) groups. Outcomes were assessed using the Modified Tardieu Scale (MTS), Berg balance scale (BSS), Edinburgh Visual Gait Score (EVGS) and integrated electromyography (IEMG). Treatment efficacy was defined based on improvements in the Gross Motor Function Measure-88 (GMFM-88). Logistic regression identified factors influencing rPMS efficacy.
RESULTS: The rPMS group showed significantly greater improvements in spasticity (reduced MTS and EVGS scores), balance (increased BBS scores), and muscle coordination (IEMG changes) compared to the conventional group (P < 0.05). The overall effectiveness rate was 85.00% for rPMS vs. 74.81% for conventional treatment (P = 0.036). Multivariate analysis identified the type of CP (diplegia vs. hemiplegia) and patient compliance as significant factors influencing the efficacy of rPMS.
CONCLUSION: Our results indicate that rPMS significantly controls spasticity and improves lower limb motor function. Importantly, we identified that certain types of CP and patient compliance are significant predictors of treatment efficacy. These findings suggest that optimizing rPMS protocols based on patient-specific characteristics can enhance therapeutic outcomes.
