简介：

Overview

This protocol outlines a motion capture methodology aimed at objectively evaluating the upper extremity movement performance and sensorimotor function in stroke patients and healthy controls. Through kinematic analysis of a standardized drinking task, the protocol seeks to quantify movement deficits that traditional clinical methods may overlook.

Key Study Components

Area of Science
