How can widening the base of support affect movement performance in assessment?

Widening the base of support is a recognized strategy that can facilitate balance and stability during movement assessments. When the base of support is broadened, individuals typically experience increased stability, which may help those who have movement difficulties, such as individuals undergoing rehabilitation after a stroke. This method effectively regresses the movement assessment because it simplifies the task, allowing the individual to focus on the fundamental aspects of the movement without the added challenge of maintaining balance.

In rehabilitation contexts, adjusting the base of support can foster confidence in individuals, encouraging better engagement in activities. As the individual gains more control and ability, the base can then be gradually narrowed, increasing the challenge and progressing the assessment. This sequential approach is crucial in stroke rehabilitation, where the goal is to build on foundational movements before progressing to more complex tasks. Widening the base of support creates a supportive environment that assists in the assessment of movement quality and motor control.
