Abstract

Abstract:

Objective To investigate the effect of local vibration therapy (LVT) on fine motor function of upper extremity and surface electromyography characteristics in children with spastic hemiplegic cerebral palsy (SHCP). Methods Sixty children with SHCP were divided into the observation group and the control group using random number table method, with 30 cases in each group. The control group was given conventional rehabilitation treatment (physical therapy, occupational therapy, sensory integration training, physiotherapy and rehabilitation therapy of traditional Chinese medicine), while the observation group received LVT for the affected upper extremity in addition to conventional rehabilitation treatment. Both groups were treated for 12 weeks. Fine motor function of upper extremity on the hemiplegic side[Peabody Developmental Motor Scale-Fine Motor (PDMS-FM), Fine Motor Function Measure (FMFM)]and root mean square (RMS) value of the biceps surface electromyography were compared between the two groups as well as before and after treatment. Results Compared with those before treatment, both groups showed increases in PDMS-FM scores for grasping energy range, visual-motor integration energy range, fine motor development quotient, FMFM scores for upper extremity joint mobility ability, grasping ability, operation ability, hand-eye coordination ability and total scores, but a decrease in RMS value of biceps brachii after treatment (P<0.05). After treatment, PDMS-FM scores for grasping energy range and visual-motor integration energy range, FMFM scores for upper extremity joint mobility ability and grasping ability and total score were higher in the observation group than those in the control group. The RMS value of biceps brachii was lower in the observation group than that of the control group (P<0.05). Conclusion LVT can enhance the effect of conventional rehabilitation on fine motor function of upper extremity and electromyography characteristics in children with SHCP.
