Limits of Stability in Sitting in Healthy Controls and Participants Post Stroke

KU Leuven49 enrolled

Overview

In this cross-sectional study we will compare the limits of stability in non-ambulatory participants post stroke compared to healthy controls. This will be done by placing participants in a seated position on a force platform, that will measure centre of pressure displacements during a leaning task in multiple directions. The results of the limits of stability test will be compared to standard clinical Measures of trunk control and functional balance, to see if there is a relationship between both ways of measuring. And how balance and trunk control are affected in the subacute stroke population.

Outcomes

Primary Outcomes

Limits of Stability Testing

The centre of pressure(COP) movement is measured while the patient is seated on a force platform and is asked by the software that is projected on a screen, to lean with the trunk in a certain direction and hold this position before going back to the starting position. The COP distance between start and end position is calculated, as well as the COP length of the trajectory that it takes the participant to reach his or her maximum leaning position.

Time frame: Baseline

Berg Balance Scale

The Berg Balance Scale (BBS) is used to assess functional balance. The scale consists of 14 items, for each item the minimum score is 0 points, the maximum score is 4 points. A total amount of 56 points can be achieved on the Berg Balance Scale which indicates a normal balance for adults. A score lower than 45 points in elderly indicates that individuals may be at greater risk of falling.

Time frame: Baseline

Trunk Impairment Scale

The Trunk Impairment Scale (TIS) assesses static and dynamic sitting balance and coordination of trunk movement. The test consists of 17 items with a minimum score of 0 and a maximum score of 23 points, which is calculated by adding up the scores from the subscales (0-7 Points for static sitting Balance, 0-10 Points for dynamic sitting Balance, 0-6 Points for coordination), with a higher scores for better trunk control.

Time frame: Baseline

Trunk Control Test

The Trunk Control Tests consists of four items with a maximum score of 100 points. The patient is asked to turn in bed, come from lying to sitting at the bedside and stay seated at the bedside. A higher score shows better functioning.
