Abstract: Objective To explore the effect of Jian Zu San Zhen acupuncture on tip foot in children with spastic cerebral palsy.Methods From January to December, 2016, 120 children with spastic cerebral palsy aged one to six years were randomly divided into control group (n=60) and observation group (n=60). Both groups were treated with conventional rehabilitation, while the observation group added Jian Zu San Zhen acupuncture. They were evaluated with Gross Motor Function Measure (GMFM), foot dorsiflexion angle and surface electromyography.Results After treatment, the scores of GMFM in B, C, D and E dimensions and the total score significantly increased in the observation group (t>4.325, P<0.001), and were higher than that of the control group (t>2.711, P<0.01); the foot dorsiflexion angle significantly decreased in the observation group (t=17.627, P<0.001), and was significantly less than that of the control group (t=15.416, P<0.001). The root mean square (RMS) of surface electromyography of gastrocnemius muscle under active plantarflexion and passive dorsiflexion of ankle joint improved after treatment (t≥3.058, P<0.01), and was better in the observation group than in the control group (t=-2.199, P<0.05).Conclusion Jian Zu San Zhen acupuncture can effectively reduce the gastrocnemius muscle tension, and do not reduce the gastrocnemius muscle strength, which could also improve the ability of foot flexion, and facilitate to recover the function of standing and moving.
