Abstract
Shoulder hand syndrome (SHS) is a common complication of stroke. This meta-analysis aimed to evaluate the effectiveness of Huangqi Guizhi Wuwu decoction (HGWD) combined with rehabilitation training in managing it, as its efficacy remains inconclusive. Seven databases, including PubMed, EMBASE, Cochrane Library, SinoMed, Chinese National Knowledge Infrastructure, Wanfang Data, and VIP database were searched in this study. The search deadline was April 30, 2023. Randomized controlled trials that included either standalone rehabilitation training or HGWD combined with rehabilitation training were included, and data were independently extracted by 2 reviewers who assessed the risk of bias. Thirteen studies involving 1270 patients were included in this study. Meta-analysis showed that the combined treatment was significantly more effective than standalone rehabilitation therapy (odds ratio = 4.49; 95%CI: 2.98-6.76; Z = 7.17; P < .00001). Compared with the control group, the intervention group had a lower visual analog scale score (mean difference [MD] = -2.80, 95%CI (-3.15, -2.45), Z = 15.84, P < .00001). In addition, the Fugl-Meyer assessment scale score improved (MD = 9.69, 95%CI (7.60, 11.78), Z = 9.08, P < .00001). The SHS score in the intervention group decreased more compared to the control group (standard mean difference = -2.27, 95%CI (-3.19, -1.34), Z = 4.79, P < .00001). Serum biomarkers related to SHS decreased, including serum substance P (MD = -7.52, 95%CI (-8.55, -6.48), Z = 14, P < .00001) and bradykinin (MD = -1.81, 95%CI (-2.68, -0.95), Z = 4.1, P < .00001). Although there was no statistical difference in joint mobility score (MD = -4.19, 95%CI (-8.16, -0.22), Z = 4.79, P = .28), sensitivity analysis after excluding one study still suggested that the joint mobility score of the combined treatment group was higher than that of the standalone rehabilitation treatment group. The results of this study indicate that HGWD combined with rehabilitation training may be more effective in treating SHS after stroke compared to standalone rehabilitation therapy.
