Objective To observe the effect of Kinesio taping combining with sling exercise therapy (SET) on the motor function for children with spastic hemiplegia. Methods From October, 2014 to April, 2016, 60 children with spastic hemiplegia of cerebral palsy were randomly divided into control group (n=20), SET group (n=20) and observation group (n=20), who accepted routine rehabilitation, routine rehabilitation+SET and routine rehabilitation+SET+Kinesio taping, respectively. They were assessed with Mallet Score, modified Ashworth Scale (MAS), Peabody Developmental Motor Scale-fine motor (PDMS-2FM) and Gross Motor Function Measure (GMFM)-C zone before and three months after treatment. Results The Mallet Score and the scores of PDMS-2FM and GMFM-C improved in all the groups after treatment (t>2.074, P<0.05), and improved the most in the observation group (F>10.032, P<0.001). The score of MAS decreased in the observation group after treatment (t=4.767, P<0.001), and was the least among these groups (F=4.262, P<0.05). Conclusion Kinesio taping combining with SET can improve the motion in the children with spastic hemiplegia, and promote the development of both fine and gross motor function.
