title: Three measures of functional outcome for lower limb amputees: a retrospective review.
abstract: Outcome measures are becoming increasingly important in health care. Functional outcome measures are of particular importance for lower limb amputees since much of the rehabilitation process is concerned with increasing mobility and personal independence. The Scottish Physiotherapy Amputee Research Group (SPARG) has used three measures of functional outcome: the Barthel Index, Russek's classification and the Locomotor Index. The review reported here involves 938 patients having a primary amputation at the transtibial or transfemoral level between October 1992 and July 1997. Differences in function due to age and level of amputation are well known clinically and the measures were compared by looking at their ability to detect these differences. The Barthel Index lacked sensitivity because of ceiling effects and should not be considered as a suitable functional outcome measure for amputee patients. Russek's classification does detect significant differences but requires a large number of patients making it unsuitable for single hospital investigations. The Locomotor Index demonstrates significant differences due to age and amputation level despite fewer patients being assessed by this measure during the period covered by this paper. The range of the Locomotor Index can be extended to cover more active amputees by considering its 'advanced activities' subscale separately. The Locomotor Index is a promising measure and should be considered by rehabilitation teams looking for a valid, reliable and sensitive functional outcome measure for use with lower limb amputees.
