Abstract:

Objective　To observe the efficacy and safety of Tiaoshen Shujin acupuncture therapy on post-stroke ankle dorsiflexion dysfunction. Methods　A total of 90 patients with post-stroke ankle dorsiflexion dysfunction treated in Shaanxi Provincial Hospital of Traditional Chinese Medicine from March 2022 to February 2024 were prospectively selected and were randomly divided into two groups by the envelope method, with 45 cases in each group. In the feedback group, there were 26 males and 19 females, aged 42-78 (62.24±7.44) years, the stroke duration was 3-12 (7.74±1.24) weeks, and the hemiplegia was on the left side in 21 cases and right side in 24 cases. In the acupuncture group, there were 24 males and 21 females, aged 40-76 (61.94±7.57) years, the stroke duration was 3-12 (7.69±1.30) weeks, and the hemiplegia was on the left side in 23 cases and right side in 22 cases. Both groups were given early rehabilitation training intervention, the feedback group was given myoelectric biofeedback intervention, and the acupuncture group was combined with Tiaoshen Shujin acupuncture therapy on the basis of the feedback group. Both groups were treated continuously for 4 weeks. The gait parameters, active range of motion (AROM) and surface electromyographic indexes of the ankle joints, Fugl-Meyer Assessment Scale for Lower Extremity (FMA-LE) score, Holden Functional Ambulation Category (FAC) score, modified Barthel index (MBI), and clinical spasm index (CSI) were compared between the two groups before and after treatment. Statistical methods used were t test and χ² test. Results　After treatment, the step length, step speed, and step frequency in the acupuncture group were higher than those in the feedback group [(37.44±2.91) cm vs. (34.23±2.58) cm, (57.26±5.82) cm/s vs. (52.84±5.16) cm/s, (69.85±7.04) steps/min vs. (64.46±6.89) steps/min], but the support phase time on the affected side was lower than that in the feedback group [(55.25±5.79)% vs. (58.98±6.42)%], with statistically significant differences (t=5.537, 3.812, 3.671, and 2.894, all P<0.05); the integrated electromyography (iEMG) values of the tibialis anterior muscle and the lateral head of the gastrocnemius muscle in the acupuncture group were higher than those in the feedback group, and the co-contraction ratio (CCR) of dorsiflexion of the affected ankle was lower than that in the feedback group, with statistically significant differences (t=11.913, 4.386, and 3.768, all P<0.05); the scores of FMA-LE, FAC, and MBI and ankle AROM in the acupuncture group were higher than those in the feedback group [(18.69±3.02) points vs. (15.27±2.78) points, (3.71±0.96) points vs. (3.21±0.78) points, (52.64±8.16) points vs. (43.59±7.48) points, (7.23±1.74)° vs. (6.06±1.65)°], but the CSI was lower than that in the feedback group [(8.97±1.24) points vs. (10.34±1.55) points], with statistically significant differences (t=5.589, 3.254, 5.484, 3.273, and 5.589, all P<0.05). The total effective rate of the acupuncture group was higher than that of the feedback group [91.11% (41/45) vs. 75.56% (34/45)], with a statistically significant difference (χ²=3.920, P<0.05). Conclusion　Tiaoshen Shujin acupuncture therapy combined with electromyographic biofeedback intervention can improve ankle dorsiflexion function, walking independence, and therapeutic effect in patients with post-stroke ankle dorsiflexion dysfunction.
