Abstract
Objective
The study purpose was three-fold: (a) to describe the development of the Functional Lower-Limb Amputee Gait Assessment, (b) to determine its reliability with two groups of raters, physical therapists, and certified prosthetists, and (c) to determine the agreement on its results between the two groups.
Design
A reliability study.
Setting
Institution for higher education.
Participants
Five physical therapists and five certified prosthetists.
Intervention
Not applicable.
Main measure
The gait of people with unilateral lower limb amputation was evaluated using the Functional Lower-Limb Amputee Gait Assessment. Kappa statistic was used to analyze reliability.
Results
The intra-rater reliability of nine gait deviations in the physical therapists’ group and eight in the certified prosthetists’ group was between moderate and almost perfect agreement (kappa = .41–1). In the physical therapists’ group, the inter-rater reliability of four gait deviations was moderate (kappa = .41–.6). In the certified prosthetists’ group, the inter-rater reliability of six gait deviations was moderate to substantial (kappa = .41–.8). Three gait deviations achieved moderate agreement in both groups of clinicians (kappa = .41–.6).
Conclusions
Most gait deviations included in the Functional Lower-Limb Amputee Gait Assessment appear stable over time when used by the same clinician. Six gait deviations in the certified prosthetists’ group and four in the physical therapists’ group may be used by multiple clinicians, and three gait deviations may be used across both professions to assist in communication and collaboration on the best course of treatment for a patient with a unilateral lower limb amputation.
