Objective: To investigate the effects of core stability training combined with Bobath therapy on lower limb function and balance ability of stroke patients. Methods: 44 stroke patients were randomly divided into control group and observation group with 22 patients in each group. The patients in control group were given conventional rehabilitation training; While the patients in observation group were also given core stability training combined with Bobath therapy. FMA scale, Sheikh scale, BBS scale, Holden walking function grading were used to evaluate the lower limb motor function, trunk control ability, balance ability and walking function of patients before training and 8 weeks training; Tape to measure the simple intra-abdominal pressure. Results: The FMA score, Sheikh score, BBS score and Holden score of patients in 2 groups after training were obviously higher than that before training (P<0.05); the intra-abdominal pressure was obviously lower (P<0.05). Moreover, the four scores and intra-abdominal pressure of patients in observation group improved significantly better than control group (P<0.05). Conclusions: Core stability training combined with Bobath therapy can obviously improve the lower limb function and balance ability of stroke patients on the basis of conventional rehabilitation training.
