Effect of hand-function robotic mirror therapy on hand function in patients with complex regional pain syndrome after stroke
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 re-ceived 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 meth-od 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 e-dema 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.
