Abstract:

Objective　To study the effect of yin-yang penetrating acupuncture combined with continuous passive motion (CPM) on the stability of knee joint in patients with knee hyperextension after stroke. Methods　The clinical data of 80 patients with knee hyperextension after stroke admitted to Shaanxi Hospital of Traditional Chinese Medicine from February 2021 to May 2024 were retrospectively analyzed, and they were divided into a study group (44 cases) and a control group (36 cases) according to different treatment methods. There were 30 males and 14 females in the study group, with an age of (57.03±4.79) years old and a disease course of (1.45±0.27) months. In the control group, there were 29 males and 7 females, with an age of (55.81±4.52) years old and a disease course of (1.39±0.21) months. The control group received CPM on the basis of routine rehabilitation exercises (10 to 15 minutes each time, 3 to 4 times a week, and the frequency and duration could be gradually increased as the rehabilitation progressed), and the study group received yin-yang penetrating acupuncture on the basis of the control group (once a day, 5 days a week). Both groups were treated continuously for 2 weeks. The χ² test was used to compare the clinical efficacies of the two groups. The t test was used to compare the times of knee hyperextension, 10 m walk time tests (10 MWT), Fugl-Meyer Motor Function Assessment of Lower Extremity (FMA-LE) scores, and Berg Balance Scale (BBS) scores of the two groups before treatment and 2 weeks after treatment. Results　The effective rate of the study group was higher than that of the control group [88.64% (39/44) vs. 69.44% (25/36)], with a statistically significant difference (χ²=4.558, P=0.033). After 2 weeks of treatment, the times of knee hyperextension and 10MWT decreased in both groups; the times of knee hyperextension and 10MWT in the study group were (14.27±2.19) times and (27.15±2.19) s, which were lower than those in the control group [(17.86±2.46) times and (32.12±3.28) s], with statistically significant differences (all P<0.05). The FMA-LE and BBS scores increased in both groups; the FMA-LE and BBS scores of the study group were (22.19±2.82) points and (23.01±1.75) points, which were higher than those of the control group [(19.42±2.70) points and (20.63±2.14) points], with statistically significant differences (all P<0.05). Conclusion　Yin-yang penetrating acupuncture combined with CPM can reduce the times of knee hyperextension in patients with knee hyperextension after stroke, and improve the walking speed, motor function, and balance ability of lower limbs.
