Whole-body angular momentum during stair ascent and descent in individuals with and without knee osteoarthritis.

Given the higher fall risk and the fatal sequelae of falls on stairs, it is worthwhile to investigate the mechanism of dynamic balance control in individuals with knee osteoarthritis during stair negotiation. Whole-body angular momentum ([Formula: see text]) is widely used as a surrogate to reflect dynamic balance and failure to constrain [Formula: see text] may increase the fall risk. This study aimed to compare the range of [Formula: see text] between people with and without knee osteoarthritis during stair ascent and descent.

Effect of acceleration and deceleration distance on the walking speed of people with chronic stroke.

Objective: To examine the effect of acceleration and deceleration distance (0, 1, 2 and 3 m) on the comfortable and maximum walking speeds in: (i) the 5-m walk test (5mWT); and (ii) the 10-m walk test (10mWT) in people with chronic stroke.

Design: Cross-sectional study.

Setting: University-based rehabilitation centre.
