An Objective Assessment Scale for "Come-to-Sit" Using a Specifically Designed Jacket in Stroke Patients

ABSTRACT

OBJECTIVE: To compare an objective assessment scale for "come-to-sit" in stroke patients with the previously established subjective assessment scales of "performance-based assessment" and the "ability for basic movement scale". METHOD: A specifically designed jacket was used to determine the objective degree of assistance needed for patients to perform the task. While patients were sitting up, the investigator evaluated the amount of assistance needed in a fully dependent state (A) and with maximal effort (B). Using this measure, we obtained an objective scale, {(A-B)/A} x100. In addition, patients were tested in two starting positions hemiplegic-side lying and sound-side lying. We then compared the objective scale with subjective scales and other parameters related to functional outcomes. RESULTS: For both starting positions, the objective assessment scale showed high correlation with the previously established subjective scales (p<0.01). Only the hemiplegic-side lying-to-sit objective scale showed a significant correlation with the parameters used to assess functional outcomes (p<0.05). In terms of Brunnstrom stages, only the leg stage showed a significant correlation with the objective "come-to-sit" scale (p<0.01). CONCLUSION: The objective scale was comparable to established subjective assessment scales when used by an expert. The hemiplegic-side lying-to-sit maneuver had a high correlation with patient's functional recovery. Specifically, balance and lower extremity function appear to be important factors in the "come-to-sit" activity.
