Objective:To investigate the effects of Jin's three needles combined with neuromuscular electrical stimulation on electromyography (EMG), muscle strength, and lower limb motor function in patients with hemiplegia after stroke.Methods:A total of 102 patients with hemiplegia after ischemic stroke who received treatment in Dongyang People's Hospital from July 2021 to August 2022 were included in this randomized controlled study. They were divided into a treatment group and a control group ( n = 51 per group) using a random number table method. The treatment group was given Jin's three needles combined with neuromuscular electrical stimulation, and the control group was given neuromuscular electrical stimulation alone. The National Institutes of Health Stroke Scale (NIHSS) was used to assess the degree of neurological impairment. The modified Barthel Index (MBI) score was used to assess a patient's self-care ability. EMG was performed to record myoelectric signals. The Fugl-Meyer Assessment Scale was used to evaluate a patient's lower limb motor function. Manual Muscle Testing was performed to measure a patient's muscle strength. The degree of nerve defect, self-care ability, lower limb motor function, hip flexion muscle strength, knee extensor muscle strength, and ankle dorsalis extensor muscle strength were compared before treatment and after 2 weeks of treatment. Results:After treatment, the NIHSS score in the treatment and control groups significantly decreased compared with those before treatment [(10.14 ± 3.45) points vs. (3.80 ± 1.92) points, (10.10 ± 3.17) points vs. (6.18 ± 2.15) points, t = 17.31, 19.08, both P < 0.05]. After treatment, the NIHSS score in the treatment group was lower than that in the control group ( t = -5.87, P < 0.001). After treatment, the integral EMG values of the tibialis anterior muscle, gastrocnemius muscle, and quadriceps femoris in the treatment and control groups were increased compared with those before treatment [(20.43 ± 5.26) points vs. (48.14 ± 10.41) points, (16.20 ± 2.62) points vs. (24.69 ± 4.07) points, (32.62 ± 3.42) points vs. (43.40 ± 4.69) points; (20.40 ± 5.19) points vs. (35.45 ± 7.41) points, (16.32 ± 2.51) points vs. (20.91 ± 3.45) points, (32.59 ± 3.37) points vs. (37.39 ± 4.06) points, t = -23.79, -16.11, -19.89; -21.92, -10.86, -8.71, all P < 0.05]. After treatment, the integral EMG values of the tibialis anterior muscle, gastrocnemius muscle, and quadriceps femoris in the treatment group were significantly higher than those in the control group ( t = 7.09, 5.05, 6.92, all P < 0.001). After treatment, The Fugl-Meyer Assessment scale score in the treatment and control groups were significantly increased compared with that before treatment [(17.61 ± 8.93) points vs. (27.16 ± 5.84) points, (17.53 ± 7.59) points vs. (22.22 ± 6.66) points, t = -14.64, -10.72, both P < 0.05). After treatment, The Fugl-Meyer Assessment scale score in the treatment group was significantly higher than that in the control group ( t = 3.98, P < 0.001). After treatment, hip flexion muscle strength, knee extensor muscle strength, and ankle dorsalis extensor muscle strength in the treatment and control groups increased compared with those before treatment. After treatment, hip flexion muscle strength, knee extensor muscle strength, and ankle dorsalis extensor muscle strength in the treatment group were significantly higher than those in the control group [(3.75 ± 0.63) grades vs. (3.31 ± 0.65) grades, (3.51 ± 0.67) grades vs. (3.08 ± 0.87) grades, (2.98 ± 0.81) grades vs.(2.35 ± 1.06) grades, t = 3.41, 2.80, and 3.36, all P < 0.05]. Conclusion:Jin's three needles combined with neuromuscular electrical stimulation can improve EMG findings, increase muscle strength, and lower limb motor function in patients with hemiplegia after stroke
