Subjects assessed their ability to do the following tasks:
1) dress/groom; 2)arise; 3) eat; 4) walk; 5) reach; 6) grip; 7) maintain hygiene; and 8) maintain daily activity. Subjects assessed their ability to do the tasks over the past week by marking responses on a questionnaire. Possible responses (scores) for each task: without any difficulty (0); with some difficulty (1); with much difficulty (2); and unable to do (3). Scores on each task were summed and averaged to provide an overall score (range = 0 to 3). Negative mean changes from baseline in the overall score indicate improvement.
