Brief summary
This study aims to evaluate the combined efficacy of repetitive Transcranial Magnetic Stimulation (rTMS) and Electroacupuncture (EA) in improving motor function recovery post-stroke, compared to rTMS combined with sham EA. Participants will receive either active EA or sham EA alongside standard rTMS treatment. Outcomes will be assessed using standardized clinical scales and neuroimaging techniques to explore underlying neuroplasticity mechanisms.
Detailed description
Motor impairment is a major cause of disability following stroke, with central and peripheral neuromodulation strategies showing potential for functional recovery. Repetitive transcranial magnetic stimulation (rTMS) has been shown to promote neuroplasticity and enhance cortical excitability. Electroacupuncture (EA), by increasing somatosensory input, may further strengthen sensorimotor integration and cortical remodeling. However, limited clinical trials have systematically evaluated the synergistic effect of rTMS combined with EA. This multi-center randomized controlled clinical study aims to assess the efficacy of combining rTMS and EA in improving motor function post-stroke. Outcome measures include clinical scales (FMA, ARAT, FAC), kinematic parameters, electrophysiological indices (EEG, EMG, TMS), blood biomarkers, and resting-state fMRI. The study is designed to explore central-peripheral neuroplasticity mechanisms and provide evidence for integrated rehabilitation approaches.
Interventions
Participants will receive electroacupuncture once daily for 2 consecutive weeks (total 10 sessions). Disposable sterile needles will be inserted at standardized acupoints to achieve de qi, then connected to an electroacupuncture device for 30 minutes per session.
Participants will receive sham electroacupuncture once daily for 2 consecutive weeks (total 10 sessions). Disposable blunt needles will be placed at the same acupoints without skin penetration or electrical stimulation, with the electroacupuncture device turned on but delivering no current, for 30 minutes per session.
Participants will receive high-frequency rTMS to the ipsilesional M1 area once daily for 2 consecutive weeks (total 10 sessions). Stimulation will be delivered with a MagPro R30 stimulator at 10 Hz, 1600 pulses per session, 4-second trains with 41-second inter-train intervals.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Fugl-Meyer Assessment (FMA) | Baseline, 2 weeks post-intervention, 1month follow-up, 3months follow-up | The Fugl-Meyer Assessment is used for rating motor function recovery after stroke. Scores range from 0 to 100, with higher scores indicating better motor performance. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Arm Research Action Test (ARAT) | Baseline, 2 weeks post-intervention, 1month follow-up, 3months follow-up | The Arm Research Action Test is used for assessing upper limb motor function across grasp, grip, pinch, and gross movement domains. Scores range from 0 to 57, with higher scores indicating better upper limb function. |
| Functional Ambulation Classification (FAC) | Baseline, 2 weeks post-intervention, 1month follow-up, 3months follow-up | The Functional Ambulation Classification is used for evaluating the degree of ambulation independence. Scores range from 0 to 5, with higher scores indicating greater ambulation capability. |
| Modified Barthel Index (MBI) | Baseline, 2 weeks post-intervention, 1month follow-up, 3months follow-up | The Modified Barthel Index is used for rating the level of independence in daily living activities. Scores range from 0 to 100, with higher scores indicating better functional independence. |
| Stroke-Specific Quality of Life Scale (SS-QOL) | Baseline, 2 weeks post-intervention, 1month follow-up, 3months follow-up | The Stroke-Specific Quality of Life Scale is used for assessing health-related quality of life across 12 domains. Scores range from 49 to 245, with higher scores indicating better perceived quality of life. |
