---|---|---|---|---|
Primary | Fugl-Meyer Assessment for Upper Extremity | It is considered as gold standard and is the only impairment level measure recommended for stroke trials. It consists of 30 items assessing motor function and 3 items assessing reflex function. The score most applicable to task performance is given from "0, inability," "1, beginning ability," to "2, normal" (total score range, 0-66). | Change from Baseline Fugl-Meyer Assessment for Upper Extremity at 4 weeks and 12 weeks | |
Primary | Stroke-Specific Quality of Life Scale | The Stroke-Specific Quality of Life Scale assesses health-related quality of life specific to stroke survivors. 49 questions under 12 subscales. Scores range from 49-245. Higher scores indicate better functioning. | Change from Baseline Stroke-Specific Quality of Life Scale at 4 weeks and 12 weeks | |
Secondary | Barthel Index | Barthel Index is used to measure the disability experienced by the patient in performing activities of daily living. It comprises 10 items regarding activities of daily living and mobility and assesses feeding, transfer from wheelchair to bed and back, self-care, bathing, walking, climbing stairs, dressing, and bladder and bowel continence. Scoring is based on whether the patient requires help or not in performing any of the above mentioned activities. Proposed guidelines for interpreting Barthel scores are that scores of 0-20 indicate "total" dependency, 21-60 indicate "severe" dependency, 61-90 indicate "moderate" dependency, and 91-99 indicates "slight" dependency. | Change from Baseline Barthel Index at 4 weeks and 12 weeks | |
Secondary | Modified Ashworth Scale | Modified Ashworth Scale (MAS) is used to assess spasticity. Scoring: 0: No increase in tone; 1: slight increase in tone giving a catch when slight increase in muscle tone, manifested by the limb was moved in flexion or extension; 1+: slight increase in muscle tone, manifested by a catch followed by minimal resistance throughout (ROM ); 2: more marked increase in tone but more marked increased in muscle tone through most limb easily flexed; 3: considerable increase in tone, passive movement difficult and, 4: limb rigid in flexion or extension | Change from Baseline Modified Ashworth Scale at 4 weeks and 12 weeks | |
Secondary | Berg Balance Test | Berg Balance Test is consisting of 14 items and measures the ability of individuals to maintain balance while performing functional tasks. Each task is scored from 0 (cannot perform independently) to 4 (stated best performance). 0-20 points are interpreted as high risk of falling, between 21-40 points as medium risk of falling, and between 41-56 points as low risk. | Change from Baseline Berg Balance Test at 4 weeks and 12 weeks | |
Secondary | Composite Autonomic Symptom Score (COMPASS-31) | The test has 6 domains looking at autonomic symptoms: orthostatic intolerance, vasomotor, secretomotor, gastrointestinal, bladder and pupillomotor. The six domain scores sum to a total COMPASS 31 score of 0 to 100, and a higher COMPASS 31 score indicates more severe autonomic symptoms. | Change from Baseline Composite Autonomic Symptom Score at 4 weeks and 12 weeks | |
Secondary | Pittsburgh Sleep Quality Index | The Pittsburgh Sleep Quality Index (PSQI) is a self-rated questionnaire which assesses sleep quality and disturbances over a 1-month time interval. Each item is weighted on a 0-3 interval scale. The global PSQI score is then calculated by totaling the seven component scores, providing an overall score ranging from 0 to 21, where lower scores denote a healthier sleep quality. | Change from Baseline Pittsburgh Sleep Quality Index at 4 weeks and 12 weeks |
