| Objective: To observe the effect of PNF on the trunk control in patients with stroke before and after treatment and the changes of surface electromyography of trunk flexor and extensor muscles. Methods: Thirty patients with stroke were randomly divided into treatment group (n=15) and control group (n=15). The control groups was given conventional rehabilitation intervention, and the treatment group accepted PNF trunk training on the basis of conventional rehabilitation intervention. The two groups were assessed with trunk control test (TCT), Berg balance function scale (BBS), Fugl-Meyer motor function scale (FMA) and surface root mean square value (RMS) before and 4 weeks after treatment. Results: After 4 weeks of treatment, TCT, BBS and FMA scores in both groups were significantly higher than those before treatment (all P<0.05), and those in the treatment group were significantly higher than those in the control group (all P<0.05). Before treatment, the RMS of the affected side of rectus abdominis and erector spinal muscles in the two groups was significantly less than that of the healthy side (all P<0.05). After 4 weeks of treatment, RMS of the rectus abdominis and the erector spinal muscles in both groups was significantly increased as compared with that before treatment (all P<0.05), and RMS of the uninjured rectus abdominis and the erector spinal muscles in the treatment group was significantly increased as compared with that before treatment (all P<0.05). The RMS of the healthy rectus abdominis and the erector spinal muscles in the treatment group was significantly greater than that in the control group (all P<0.05). Conclusions: PNF technology can improve the trunk control ability and the function of balance, and promote the motor function recovery of patients. |
