| Objective: To observe the efficacy of hand-function robotic mirror therapy on hand function in patients with complex regional pain syndrome (CRPS) after stroke. Methods: Totally, 40 inpatients with CRPS after stroke were randomly divided into a control group (n=21) and an experimental group (n=19) according to the random number method. The control group received conventional rehabilitation treatment, and the experimental group received conventional rehabilitation treatment and hand-function robotic mirror treatment. Before and 6 weeks after treatment, CRPS Severity Score (CSS) was recorded to evaluate the severity of the disease, visual analogue scale (VAS) was assessed for pain degree, grip strength body mass index was used to evaluate grip ability, Fugl-Meyer assessment upper extremity (FMA-UE) hand score was used to assess hand function, and water displacement method was used to measure changes in hand volume. Results: After 6 weeks of treatment, the CSS, VAS and volume of affected hand in both groups were lower than before treatment (P<0.01), and the body mass index of grip strength, FMA-UE hand score in the experimental group were higher than before treatment (P<0.05). CSS and edema volume of affected hand in the experimental group were significantly lower than those in the control group (P<0.05), and body mass index of grip strength and FMA-UE score in the experimental group were significantly higher than those in the control group (P<0.05). Conclusion: Hand-function robotic mirror therapy could promote the recovery of hand function in patients with CRPS after stroke. |
