Evaluating the effects of loaded sit-to-stand resistance exercises on gross motor functions in spastic diplegic children with cerebral palsy

Introduction: Muscle strength is one of the most important and effective factors in movement disordersof spastic diplegic children with cerebral palsy. Respecting the fact that strength can influence gross motorfunctions, the aim of this study was to measure the effects of loaded sit-to-stand resistance exercises onsuch functions in this group of children with cerebral palsy. Materials and Methods: 20 cerebral palsy children with spastic diplegia (12 boys and 8 girls), agedbetween 5 and 12 years (mean, 8.30 years), participated in this study. Loaded sit-to-stand resistanceexercises were performed 3 times a week for 6 weeks. Isometric strength of hip extensor, knee extensorand ankle plantar flexor were evaluated by MMT NICHOLAS apparatus. Gross motor functions weremeasured via GMFM. Data were statistically analyzed through paired t test. Results: The strength of hip extensor and knee extensor increased significantly (P < 0.0001). Moreover,the scores of GMFM dimensions D and E improved significantly (P < 0.0001). Conclusion: Loaded sit-to-stand resistance exercises may enhance muscle strength of lower extremity andincrease scores of GMFM.
