The purpose of occupational therapy is to promote a fit, or match, between the person, the task, and the environment. To facilitate the person-task-environment fit, therapists may adapt task demands, environmental parameters, and personal approaches to tasks. A review of occupational therapy literature suggests that little is known about the effects of environmental parameters and personal approaches. The first two chapters of this dissertation investigated the effect of part task strategy (i.e., personal approach) and the third chapter examined the effect of start signals (i.e., environmental parameter).

520 $a The purpose of occupational therapy is to promote a fit, or match, between the person, the task, and the environment. To facilitate the person-task-environment fit, therapists may adapt task demands, environmental parameters, and personal approaches to tasks. A review of occupational therapy literature suggests that little is known about the effects of environmental parameters and personal approaches. The first two chapters of this dissertation investigated the effect of part task strategy (i.e., personal approach) and the third chapter examined the effect of start signals (i.e., environmental parameter).
520 $a The first chapter of this dissertation compared the kinematic performance of community-dwelling elderly people when they performed a three-step task in a continuous flow of action versus when they performed the task in a step by step manner. Using a counterbalanced repeated-measures design, this study found that doing the task as a whole elicited a more efficient, more forceful, and smoother movement than doing the task step by step. Chapter 2 replicated the first study and extended it to include a clinical population of patients with Parkinson's disease (PD). Although a general impression about PD is that the patients usually have problems with sequential movement, the findings of this study indicated that patients with PD, like control subjects, elicited better performance (i.e., more efficient, more forceful, etc.) when doing the task in its entirety than when doing the task one step at a time. The findings suggest the importance of keeping a three-step functional task whole during the therapeutic process.
520 $a Chapter 3 investigated whether start signals, which are commonly used in motor behavioral research and in therapeutic encounters, affected kinematic performance of patients with PD in a sequential writing task. The results indicated that presence of start signals affected movement kinematics of patients with PD, but not that of control subjects. The findings suggest that because the utilization of start signals facilitates patients' performance, researchers should be cautious when using start signals in motor behavioral studies in PD.
