OBJECTIVE This study investigated whether affording objects with different levels of functional support would have an impact on reaching performance in patients after cerebrovascular accident (CVA) and in adults who were neurologically intact. Reaching performance was quantitatively analyzed, using several kinematic variables. METHOD Two groups, 14(More)
OBJECTIVE To examine the effects of context on reaching performance in neurologically impaired and intact populations. Context was varied by the presence or absence of objects used to complete a task. DESIGN A counterbalanced repeated-measures design. SETTING A motor control laboratory in a university setting. PARTICIPANTS Fourteen persons with stroke(More)
Thirteen patients with left neglect performed line bisection under four conditions: no cue, visual cueing involving the report of a digit placed at the left end of the line, circling the left-end digit, and digit circling plus tracing of the line with the right index finger from its left end to its midpoint before bisection. Digit circling plus finger(More)
OBJECTIVES This study examined, through kinematic analysis, the effect of occupational form on reaching performance. The hypothesis was that reaching performance would show an enhanced quality of movement in materials-based occupation (i.e., pick up a pencil and prepare to write one's own name) than in imagery-based occupation (i.e., pretend to pick up a(More)

Unilateral neglect is a common neurological syndrome resulting from right-hemisphere strokes and has important prognostic value for functional outcome. This article identifies three approaches to neglect rehabilitation that are based on right-hemispheric activation mechanisms: (a) the lateralized task approach, (b) the controlled sensory stimulation(More)
OBJECTIVE This study investigated (a) whether the kinematic profile of a reaching-for-an-object movement would differ depending on the goal of the reaching task and (b) the effect of task goal on attentional carryover. METHOD Twenty-four adults without disabilities performed a horizontal line bisection task under three conditions: (a) a natural condition(More)
BACKGROUND AND PURPOSE Current theories of motor control in rehabilitation focus on how the nervous system responds to many types of external and internal constraints to execute motor behavior to accomplish a task. However, the dynamic interplay between these 2 constraints remains unclear. This study examined the impact of some aspects of internal and(More)
In this paper, a systematic procedure to design the robust ∞ H fuzzy controller for a nonli-near active magnetic bearing (AMB) system affected by time-varying parametric uncertainties is presented. First, the continuous-time Takagi-Sugeno (T-S) fuzzy model is employed to represent the non-linear AMB system. Next, based on the obtained fuzzy model,(More)
