Balance is beneficial for daily functioning of patients with a
lower limb amputation and sometimes assessed by the one-leg stand test (OLST).
The aims of the study were to examine (1) the number of trials needed to achieve
performance stability, (2) the interrater reliability of the OLST in patients
with a major non-traumatic lower limb amputation, and (3) to provide a test
procedure. METHODS: Thirteen women and 23 men with a mean age (SD) of 67.4 (10.6)
years; 19 below-knee and 17 above-knee amputees who performed the OLST at a mean
of 14.5 (4.5) days post-amputation. All patients performed five timed OLST-trials
with 1-min rest intervals between trials, supervised by a physical therapist, of
which 28 included in the reliability-part conducted this twice, separated with a
mean of 3.4 (0.78)h. Repeated measures Friedman determined the number of trials
needed to ensure stable OLST-scores while the ICC1.1, the standard error of
measurement (SEM) and the smallest real difference (SRD) determined
reproducibility. RESULTS: No learning curve was found for the five OLST-trials
(p=0.241), with the best of the five trials reaching a median (25-75% quartile)
of 2.9 (1.7-8.2)s, and with only six patients able to stand for more than 10s.
The ICC (95% CI), SEM and SRD were respectively 0.87 (0.61-0.96), 0.99 s and 2.74
s. CONCLUSION: Findings suggest that the best of five trials be used for the OLST
in unilateral non-traumatic amputee patients as we found excellent interrater
reliability and acceptable agreement when using this score.
