Repeatability of a new observational gait score for unilateral lower limb amputees.
The aim of this study was to assess the repeatability of an observational gait analysis score that was developed specifically for unilateral amputees. Ten videotaped sequences were analysed by six experienced observers on two separate occasions. Data were analysed using percentage agreement, the kappa statistic and the coefficient of repeatability. The score demonstrated good intraobserver repeatability with an average repeatability coefficient of 3 (range 1.5-4.6). Interobserver repeatability was poor with a repeatability coefficient of 5.9. This score could be used in practice to assess amputees and is most repeatable if used by the same observer to evaluate changes in patients over time.
