Abstract

Gait change in the elderly may be a strategy to maintain postural stability while walking. However, gait laterality is accompanied by back pain or an increased risk of a fall. This study aimed to examine group-related differences and gait laterality in elderly females with mild or severe unilateral knee pain. Seventy-five elderly females (66–87 years old) were included, which comprised the following groups: 47 with mild unilateral knee pain and 28 with severe unilateral knee pain. They completed a 12 m walk test with maximum effort. Stance time, swing time, and step length were selected as evaluation parameters. A two-way ANOVA (group leg) was used for analysis. No significant differences were found in interaction or in either main factor of the group and leg. In conclusion, elderly females do not show group-related differences or gait laterality regardless of the degree (mild or severe) of unilateral knee pain.
