Abstract: OBJECTIVE: This study aimed to systematically compare the efficacy and safety of various neuromodulation techniques for upper limb motor function recovery after stroke, and to rank the relative advantages of different interventions through a network meta-analysis, thereby providing evidence-based guidance for clinical rehabilitation.
METHODS: A comprehensive literature search was conducted in CNKI, WanFang, VIP, CBM, PubMed, EMbase, Web of Science, and Cochrane Library from inception to August 2025. Randomized controlled trials investigating different neuromodulation techniques for post-stroke upper limb motor impairment were included. Control group received sham stimulation or conventional rehabilitation, while trial group received additional neuromodulation therapies. The methodological quality of included studies was assessed using the Cochrane Risk of Bias Tool. Network meta-analyses were performed using Stata 16.0 and RevMan 5.4 software.
RESULTS: A total of 51 randomized controlled trials were included, covering 12 neuromodulation modalities. Network meta-analysis demonstrated that, compared with conventional rehabilitation, high-frequency repetitive transcranial magnetic stimulation yielded the greatest improvement in basic motor function recovery in the upper limb (MD=11.50, 95%CI: 6.83–16.16, P < 0.05). For upper limb functional utility and dexterity, continuous theta burst stimulation showed the most favorable effects (MD=12.10, 95%CI: 44.99–19.21, P < 0.05; MD=9.60, 95%CI: 1.32–17.88, P < 0.05). For daily living ability and spasticity, cathode transcranial direct current stimulation achieved the best outcomes (MD=15.40, 95%CI: 0.03–30.77, P < 0.05; MD=–0.83, 95%CI: –1.64 to –0.03, P < 0.05).
CONCLUSION: High-frequency repetitive transcranial magnetic stimulation is most effective for promoting basic motor recovery in the upper limb. Continuous theta-burst stimulation provides superior benefits for enhancing functional utility and dexterity of the upper limb. Cathodal transcranial direct current stimulation is most effective for improving daily living ability and alleviating spasticity.
