Background and Purpose— Health-related quality of life (HRQOL) is an important index of outcome after stroke and may facilitate a broader description of stroke recovery. This study examined the relationship of individual and clinical characteristics to HRQOL in stroke survivors with mild to moderate stroke during subacute recovery. Methods— Two hundred twenty-nine participants 3 to 9 months poststroke were enrolled in a national multisite clinical trial (Extremity Constraint-Induced Therapy Evaluation). HRQOL was assessed using the Stroke Impact Scale (SIS), Version 3.0. The Wolf Motor Function Test documented functional recovery of the hemiplegic upper extremity. Multiple analysis of variance and regression models examined the influence of demographic and clinical variables across SIS domains. Results— Age, gender, education level, stroke type, concordance (paretic arm=dominant hand), upper extremity motor function (Wolf Motor Function Test), and comorbidities were associated across SIS domains. Poorer HRQOL in the physical domain was associated with age, nonwhite race, more comorbidities, and reduced upper-extremity function. Stroke survivors with more comorbidities reported poorer HRQOL in the area of memory and thinking, and those with an ischemic stroke and concordance reported poorer communication. Conclusions— Although results may not generalize to lower functioning stroke survivors, individual characteristics of persons with mild to moderate stroke may be important to consider in developing comprehensive, targeted interventions designed to maximize recovery and improve HRQOL.

This article describes the study design, methodological considerations, and demographic characteristics of a phase III RCT to determine if 1) constraint-induced therapy (CI therapy) can be applied with therapeutic success 3 to 9 months after stroke across different sites, 2) gains that might occur persist over 2 years, 3) initial level of motor ability determines responsiveness to CI therapy, and 4) the treatment effect differs between those treated before 9 months and after 1 year. Six sites will screen and recruit poststroke survivors stratified on initial level of motor ability and after randomization allocate participants to immediate or delayed intervention. Primary outcomes include a laboratory-based measure of function (Wolf Motor Function Test [WMFT]) and a real-world participant-centered functional use measure (Motor Activity Log [MAI]). Secondary outcomes concern function, behavior, and compliance. This is the first multisite, single-blind RCT of a formal training intervention for upper extremity rehabilitation in subacute stroke in the United States.

SummaryBackground-Constraint-Induced Movement therapy (CIMT) uses a variety of treatment components, including restricted use of the better upper extremity, to promote increased use of the contralesional limb for many hours each weekday over two consecutive weeks. The EXCITE Trial demonstrated the efficacy of this intervention for patients 3-9 months post-stroke who were followed for the next 12 months. We assessed the retention of improvements through 24 months.
