脑机接口联合机器人康复、机器人辅助治疗与运动想象对上肢卒中后运动恢复的疗效比较：系统综述与网状荟萃分析
Comparative efficacy of brain-computer interface-coupled robotic rehabilitation, robot-assisted therapy, and motor imagery for upper-limb motor recovery after stroke: a systematic review and network meta-analysis
研究要解决的问题是：卒中后上肢康复中，脑机接口联合机器人训练、机器人辅助治疗、运动想象与传统康复哪种更有效。研究检索了11个数据库，纳入22个研究队列、727名参与者，主要结局为Fugl-Meyer上肢运动评分。网状荟萃分析显示，脑机接口联合机器人训练排名第一（P评分0.992），优于传统康复（平均差6.80分），也略优于单纯机器人治疗（平均差2.04分）。其相对传统康复的改善超过了最小临床重要差值，但证据区间下限未超过，额外获益幅度仍不确定。结论认为该技术有前景，但不能替代专业判断。

摘要Abstract
OBJECTIVE: To compare and rank the efficacy of brain-computer interface-coupled robotic rehabilitation (BCI-robot), robot-assisted therapy, motor imagery (MI), and conventional rehabilitation for upper-limb recovery after stroke, and to explore whether treatment effects differed according to key clinical and intervention-related characteristics.
METHODS: A systematic search was conducted in 11 databases from inception to March 31, 2026. Randomized controlled trials enrolling adults with post-stroke upper-limb motor impairment were included. The primary outcome was the Fugl-Meyer Assessment of Upper Extremity (FMA-UE). Secondary outcomes included the Action Research Arm Test (ARAT), Wolf Motor Function Test (WMFT), and Modified Barthel Index (MBI). Direct pairwise meta-analyses were performed using mean differences (MDs) with 95% confidence intervals (CIs), and a frequentist network meta-analysis was conducted to synthesize direct and indirect evidence and rank interventions using P-scores.
RESULTS: Twenty-three reports representing 22 independent study cohorts were included, comprising 727 participants. Network meta-analysis showed no significant inconsistency, and the consistency model was adopted. BCI-robot ranked highest for improving FMA-UE according to the P-score analysis (P-score = 0.992), followed by robot-assisted therapy (0.641), MI (0.240), and conventional rehabilitation (0.127). In direct comparisons, BCI-robot produced a statistically significant improvement in FMA-UE versus conventional rehabilitation (MD = 6.80, 95% CI 4.29 to 9.30). The point estimate exceeded the 5.25-point (minimal clinically important difference) MCID, although the lower confidence limit did not. Compared with robot-assisted therapy, BCI-robot showed a statistically significant but small improvement (MD = 2.04, 95% CI 0.29 to 3.78), with both the point estimate and the entire 95% CI remaining below the MCID. Follow-up-duration subgroup analyses suggested that BCI-robot remained favorable over conventional rehabilitation in both < 3-month and ≥ 3-month subgroups, whereas no significant follow-up advantage over robot-assisted therapy was observed. For secondary outcomes, BCI-robot significantly improved WMFT versus conventional rehabilitation (MD = 8.94, 95% CI 5.22 to 12.65) and MBI versus conventional rehabilitation (MD = 3.37, 95% CI 0.10 to 6.63). A significant benefit for MBI versus robot was also observed (MD = 8.61, 95% CI 1.76 to 15.46), although this result was not robust in sensitivity analysis. No significant advantage was found for ARAT. Exploratory subgroup analyses suggested that, compared with robot-assisted therapy, the additional benefit of BCI-robot was more apparent in studies delivering more than four sessions per week.
CONCLUSIONS: BCI-robot ranked highest for improving FMA-UE and may provide a clinically important benefit over conventional rehabilitation, although the magnitude remains uncertain. Its additional benefit over robot-assisted therapy was small and unlikely to be clinically important. Evidence for longer-term effects and for activity-level and daily-function outcomes remains limited, and the findings should be interpreted cautiously.
