Abstract： Objective： To observe the effects of electroacupuncture stimulation with different parameters combined with a hand function training device on upper limb motor function in stroke-induced hemiplegia. Methods： A total of 94 stroke-induced hemiplegia patients admitted to Yongkang First People′s Hospital between September 2023 and December 2024 were selected and divided into the continuous wave group （n=47） and the dense-disperse wave group （n=47） using a random number table method. Both groups received conventional rehabilitation therapy， hand function training device intervention，and electroacupuncture stimulation. The continuous wave group stimulated with continuous wave electroacupuncture， while the dense-disperse wave group stimulated with dense-disperse wave electroacupuncture. Treatment duration was six weeks for both groups. Clinical efficacy， functional recovery， serum indicators， joint range of motion， upper limb motor function， and quality of life were compared between the two groups. Results：The total effective rate in the dense-disperse wave group was 91.49% （43/47），significantly higher than that of 74.47% （35/47） in the continuous wave group （P＜0.05）. After treatment， both groups showed improvement in upper limb and hand Brunstrom stages compared to baseline， with the dense-disperse wave group demonstrating superior outcomes to the continuous wave group （P＜0.05）. Levels of white blood cell count （WBC），Creactive protein （CRP），and interleukin-6 （IL-6） decreased in both groups after treatment，with lower levels in the dense-disperse wave group （P＜0.05）. Active range of motion （AROM） for wrist dorsiflexion，Fugl-Meyer Assessment of Upper Extremity （FMA-UE） scores， and Modified Barthel Index （MBI） scores increased in both groups after treatment，with higher improvements in the dense-disperse wave group（ P＜0.05）. Conclusion：Dense-disperse wave electroacupuncture stimulation combined with a hand function training device can significantly enhance upper limb motor function， improve daily living ability， and demonstrate superior clinical efficacy in stroke patients with hemiplegia.
