Abstract
PURPOSE: To evaluate the effects of lateral electrical surface stimulation (LESS) on scoliosis and trunk balance in children with severe cerebral palsy (CP). METHODS: Children with severe CP (GMFCS level IV or V) and stationary or progressive scoliosis were enrolled. Children were recommended of two sessions of LESS/day, 1 h/session, for 3 months at home: at 40-80 mA intensity, 200 μs pulse width, 25 Hz frequency, on for 6 s and then off for 6 s on the convex side of the trunk curve. Radiologic (Cobb's, kyphotic, and sacral angles) and functional [gross motor function measurement (GMFM)-88 sitting score, and trunk control measurement scale (TCMS)] measurements were evaluated at 4 periods: (a) 3 months before, (b) just before, (c) 1 month after, and (d) 3 months after LESS. RESULTS: The median Cobb's angle of 11 children (median age, 9 years) was 25°, and it showed significant improvements after both 1 and 3 months of LESS. The LESS intensity correlated with the improvement of GMFM-88 siting score. The parents or main caregivers of the children believed LESS had several positive effects without major adverse effects. CONCLUSIONS: LESS is effective in scoliosis in children with severe CP and it may improve trunk balance. Implications for rehabilitation Scoliosis is a very complicated problem for the children with severe CP. They do not have many options for treatments and scoliosis is usually refractory. Lateral electrical surface stimulation (LESS) is effective in scoliosis in children with severe CP and it may improve trunk balance. LESS may be another option of managing stationary or progressive scoliosis in the children with severe CP who are unable to undergo surgery.
