Abstract
[Purpose] To investigate the effects of progressive functional training on lower limb muscle architecture and motor function of children with spastic cerebral palsy (CP). [Subjects] The subjects of this study were 26 children with spastic CP. [Methods] Thirteen subjects in the experimental group performed general neurodevelopmental treatment (NDT) and additional progressive functional trainings and 13 subjects in the control group performed only general NDT 3 times a week for 6 weeks. Ultrasonography, gross motor function measurement (GMFM) and the mobility questionnaire (MobQue) were evaluated. [Results] After the intervention, the muscle thickness of the quadriceps femoris (QF), cross-sectional area of the rectus femoris (RF), pennation angle of the gastrocnemius (GCM) and the MobQue score of the experimental group were significantly greater than those of the control group. The muscle thickness of QF correlated with the cross-sectional area (CSA) of RF and the pennation angle of GCM, and GMFM score correlated with the pennation angle of GCM. [Conclusion] Progressive functional training can increase muscle thickness, CSA, and the pennation angle of the lower limb muscles, and improve the mobility of spastic CP children making it useful as a practical adjunct to rehabilitation therapy.
