Objective To explore the development and clinical effect of weight_adjustable suit for children with dyskinetic cerebral palsy. Methods Twenty_six cerebral_palsy children with involuntary movement admitted to the Third Hospital Affiliated to Jiamusi University from March to October 2016 were randomly divided into the observa_tion group and the control group,13 cases in each group. The control group was treated with routine rehabilitation trai_ning. The observation group was put on adjustable heavy clothes besides conventional rehabilitation. Before and after treatment,childrenˊs functional independence and gross motor function were assessed and compared by using Wee Punc_tional Independence Measure(Wee_PIM)and Gross Motor Punction Rating Scale(GMPM_88). Results After treat_ment the Wee_PIM score of the control group was(43. 24 ± 5. 58),the GMPM score was(61. 81 ± 9. 46),the Wee_PIM score of the observation group was(50. 21 ± 6. 03),and the GMPM score was(65. 73 ± 10. 17). There were sig_nificant differences between the two groups(P〈0. 05),while the scores of the observation group were significantly higher than those of the control group,and the difference was significant(t﹦2. 582,2. 346,all P〈0. 05). Conclusions The adjustable heavy suit can effectively improve the functional independence and gross motor function of cerebral palsy children with involuntary movement and their comprehensive ability,and it is worth trying clinically.
