Changes in and Determinants of Movement Performance, Functional Status, and Health-Related Quality of Life After Stroke Rehabilitation
Study Details
Study Description
Brief Summary
A total of 144 stroke patients 6 -24 months post onset who are between 45 and 75 years old will be recruited. A randomized-blocks pretest and posttest control group design will be applied. Four groups will be involved in this project and the subjects will be stratified on two variables: impairment level of the hand and side of lesion. Randomization will be done in blocks of six and each block randomization scheme is within each stratum. Treatment regimens will be designed to ensure that patients in 4 groups receive equivalent intensity of treatment (5 days/week for 1.5 hours/day for 4 consecutive weeks) directly supervised by senior occupational therapists.
Brain and movement reorganization will be evaluated with fMRI and kinematic instrument, respectively before and after the 4-week intervention period. Clinical measures on motor impairment, daily function and quality of life will be assessed before, immediately and six months after intervention. Two examiners blind to group allocation will collaborate to provide both fMRI and kinematic evaluations and one of them will administer clinical measures. Before being allowed to work with subjects, the examiner competence will be assessed by principle investigator and co-principle investigators. Multivariate analyses of covariance will be used to examine change in brain activation, kinematic variables and clinical measures as a function of intervention while controlling for pretest data, age and onset post stroke. Multiple regression models will be established to examine the possible predictor(s) for functional outcome of each rehabilitation approach. Canonical correlation analyses will be conducted to quantify the relationship between brain/motor reorganization and clinical measures.
