Abstract: Objective To design an abdominal muscle strength trainer, and to observe its clinical efficacy in children with spastic diplegia cerebral palsy (CP). Methods An abdominal muscle strength trainer was designed, consisting of three important parts: a seat plate, a base plate and a back training plate. Forty spastic diplegia CP children were enrolled in this study from January 2018 to December 2019, and were randomly divided into observation group (n=20) and control group (n=20). All children were treated with routine rehabilitation training with the frequency of once a day, 5 d/week. The control group received conventional rehabilitation, while the observation group received abdominal muscle strength trainer exercise training for 5 - 10 min per day. Children in both groups were assessed with manual muscle testing at the beginning and at the end of the three months of treatment course. Results After three-month treatment, MMT scores of children in both groups were improved significantly than those before training (t=2.517, 7.768, 2.179, 8.718, P＜0.05).MMT scores of children in the observation group were significantly higher than those in the control group (t=3.454, 2.886, P＜0.01). Conclusions The abdominal muscle strength trainer is easy and safe for children with spastic diplegia cerebral palsy to use, and it can significantly improve the rehabilitation efficacy.

摘要： 目的 研制痉挛型脑瘫患儿用腹肌训练器并观察其在临床中的应用效果,将其应用于临床并进行推广。方法 研制脑瘫患儿用腹肌训练器,包括坐垫板、底架和背部训练板3个部分。2018年1月-2019年12月,选取由佳木斯大学附属第三医院确诊的痉挛型双瘫脑瘫患儿40例,年龄3～6岁,随机分为观察组20例和对照组20例,两组均接受常规康复训练,每周5 d、每日1次,观察组利用腹肌训练器进行腹肌训练,观察组和对照组治疗周期均为3个月,分别于治疗前、治疗后采用徒手肌力检查对患儿进行评估。结果 与治疗前相比,两组患儿治疗3个月后,徒手肌力检查结果均有一定提高,差异有统计学意义(t=2.517、7.768、2.179、8.718,P＜0.05);治疗后徒手肌力检查得分显示观察组得分显著高于对照组(t=3.454、2.886,P＜0.01)。结论 痉挛型脑瘫患儿用腹肌训练器具备操作简单、自主性强、安全有效,能够改善痉挛型双瘫患儿的腹肌力量,提升脑瘫患儿的康复效果。
