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

Maximum Weight-shifts in Sitting in Non-ambulatory People With Stroke Are Related With Trunk Control and Balance in Sitting and Standing

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.

Inclusion Criteria Participants post Stroke:

• a stroke with clear hemiplegia (a previous stroke is accepted when complete recovery was achieved)
