The Component Timed-Up-and-Go test : the utility and psychometric properties of using a mobile application to determine prosthetic mobility in people with lower limb amputations

OBJECTIVE: Using a custom mobile application to evaluate the reliability and
validity of the Component Timed-Up-and-Go test to assess prosthetic mobility in
people with lower limb amputation. DESIGN:
Cross-sectional design. SETTING: National conference for people with limb loss. SUBJECTS: A total of 118 people
with non-vascular cause of lower limb amputation participated. Subjects had a
mean age of 48 (+/-13.7) years and were an average of 10 years post amputation.
Of them, 54% ( n = 64) of subjects were male. INTERVENTION: None.
MAIN MEASURE:
The Component Timed-Up-and-Go was administered using a mobile iPad application,
generating a total time to complete the test and five component times capturing
each subtask (sit to stand transitions, linear gait, turning) of the standard
timed-up-and-go test. The outcome underwent test-retest reliability using
intraclass correlation coefficients (ICCs) and convergent validity analyses
through correlation with self-report measures of balance and mobility. RESULTS:
The Component Timed-Up-and-Go exhibited excellent test-retest reliability with
ICCs ranging from .98 to .86 for total and component times. Evidence of
discriminative validity resulted from significant differences in mean total times
between people with transtibial (10.1 (SD: +/-2.3)) and transfemoral (12.76 (SD:
+/-5.1) amputation, as well as significant differences in all five component
times ( P < .05). Convergent validity of the Component Timed-Up-and-Go was
demonstrated through moderate correlations with the PLUS-M
( rs = -.56).
CONCLUSION: The Component Timed-Up-and-Go is a reliable and valid clinical tool
for detailed assessment of prosthetic mobility in people with non-vascular lower
limb amputation.
The iPad application provided a means to easily record data,
contributing to clinical utility.
