Tests of static balance do not predict mobility performance following traumatic brain injury

Abstract

Purpose: To investigate the extent to which different single-limb support (SLS) parameters predict mobility performance following traumatic brain injury (TBI). Methods: Seventy-one people with mobility limitations following TBI were assessed for balance and mobility performance in a human movement laboratory. Participants performed a clinical test of static balance that involved balancing in SLS on each leg with eyes open and eyes closed. Mobility performance was measured by self-selected gait speed and performance on the High Level Mobility Scale (HiMAT). Dynamic stability during walking was measured by quantifying lateral centre of mass (COM) displacement, width of base of support, and pro..
