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.
