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

Area of Science:

• Rehabilitation Medicine
• Neurology
• Biomedical Engineering

Background:

• Stroke rehabilitation often relies on subjective assessments for functional recovery.
• Objective measures are needed to standardize the evaluation of motor tasks like sitting up.

Purpose of the Study:

• To develop and validate an objective assessment scale for the "come-to-sit" task in stroke survivors.
• To compare this new objective scale against established subjective assessment tools.

Main Methods:

• An objective scale was derived using a specialized jacket to quantify assistance needed for sitting up ({(A-B)/A} ×100).
• Patients were assessed from both hemiplegic-side and sound-side lying positions.
• Comparisons were made with subjective scales and functional outcome parameters.

Main Results:

• The objective "come-to-sit" scale demonstrated high correlation with existing subjective scales (p<0.01).
• The hemiplegic-side lying-to-sit maneuver showed significant correlation with functional outcomes (p<0.05).
• Correlation was observed with the leg stage of the Brunnstrom stages (p<0.01).

Conclusions:

• The novel objective scale is a reliable alternative to subjective assessments for "come-to-sit" in stroke patients.
• The hemiplegic-side lying-to-sit transition is a key indicator of functional recovery.
• Balance and lower extremity function are critical components of the "come-to-sit" activity.
