Abstract:
ObjectiveTo observe the effect of deep muscle stimulation on muscle structure and function in children with spastic cerebral palsy. MethodsFrom January, 2023 to March, 2024, 30 children with spastic cerebral palsy in Beijing Bo'ai Hospital were randomly divided into control group (n = 15) and intervention group (n = 15). Both groups received conventional rehabilitation therapy, while the intervention group added deep muscle stimulation, for four weeks. Before and after training, the gastrocnemius muscle was examined by ultrasound diagnosis system in two aspects: transverse incision and longitudinal incision. Indicators included fascicle length, muscular thickness, cross sectional area and pennation angle. The modified Ashworth Scale (MAS) was used to assess the muscle tension of the lower extremity of the affected side. The standing, walking, running and jumping function were evaluated by Gross Motor Function Measure (GMFM) D and E areas. ResultsAfter training, the fascicule length and pennation angle improved significantly in both groups (|t| > 6.329, P < 0.001), and they were better in the intervention group than in the control group (|t| > 2.347, P < 0.05); the scores of MAS decreased in both groups (t > 2.432, P < 0.05), and were better in the intervention group than in the control group (t = 2.140, P < 0.05); the scores of GMFM D and E areas significantly decreased in both groups (|t| > 8.473, P < 0.001), and were better in the intervention group than in the control group (|t| > 2.191, P < 0.05). ConclusionDeep muscle stimulation could improve the fascicule length and pennation angle, and improve the spasticity and motor function of lower extremities in children with spastic cerebral palsy.
