Seated postural stability has not been studied extensively in individuals with spinal cord injury (SCI). The main purpose of this study was to compare the
effects of upper limb (U/L) positions and U/L weight support roles on
quasi-static postural stability between individuals with SCI and healthy
controls. Fourteen individuals with SCI and 14 healthy controls sat on an
instrumented seat with their feet resting on force plates and randomly maintained
five short-sitting positions for 60s with or without hand support.
Center-of-pressure (COP) measures based on displacement and frequency series were
computed. Individuals with SCI exhibited greater mean COP displacement and
velocity measures compared to healthy controls, as well as lower COP frequency
measures, irrespective of the U/L positions and weight support roles, confirming
reduced stability and a difference in preferential postural regulation
strategies. The use of U/L support is a compensatory strategy that influences
seated stability in individuals with SCI.
