Objective To watch the effects of Hand-arm Bimanual Intensive Training (HABIT) on the children's upper limb function and ability of daily activity with hemiplegic cerebral palsy. Methods A total of 60 cases in children with hemiplegia type cerebral palsy were randomly divided into three groups:experimental A group (20 cases) and B group (20 cases) and control group (20 cases).On the basis of routine rehabilitation therapy,the control group accepted conventional OT treatment,the experimental test group treated by HABIT of 0.5 hours and 1 hour per day in experimental group A and B training intensity respectively.Three groups respectively had the upper limb skills Quality Test Scale (QUEST),Peabody Develop Getting Motor Scale-Fine Motor (PDMS-FM),Pediatric Evaluation of Disability Inventory (PEDI) before treatment and the 8^th week and the 12^th week after treatment. Results The scores of QUEST,Peabody-FM and PEDI of all children after the 8^th week,the 12^th week treatment were better than those before treatment (P<0.05),the experimental groups were better than control group (P<0.05),the experimental group B was better than the experimental group A (P<0.05);The scores after treatment of experimental A and B groups all improved,but the score of the 12^th week after treatment and that of the 8^th week had no difference (P>0.05). Conclusion HABIT treatment on children with hemiplegic cerebral palsy upper limb dysfunction can effectively improve the structure and function of hand-arm,hands collaboration performance,ability of daily life activities,higher strength HABIT training have better effect,effect of the 8^th week treatment is most significantly improved.
