OBJECTIVE: To analyze the reliability of 4 methods (water immersion,
computer-aided design [CAD] photometric method, CAD hand scanner, and
circumferential measurements) for stump volume measurement in transtibial
amputees. DESIGN: Repeated measurements. SETTING: General community, ambulatory
care. PARTICIPANTS: Transtibial amputees (N=26; mean age +/- SD, 58.7+/-11.0y).
INTERVENTIONS: Stump volume of patients with an amputation was measured on 2
occasions, each consisting of 2 sessions. In each session, stump volume was
measured by 2 observers using each of the 4 methods. Sequence of observers and
measurement methods was determined randomly. MAIN OUTCOME MEASURE: Repeatability
coefficients, as a measure for reliability, for each method were calculated, as
well as variance components to estimate the influence of measurement conditions
on stump volumes measured. RESULTS: Repeatability coefficients varied from 129mL
CAD hand scanner to 158mL CAD photometric method. Error variance contributed 12%
to the total variance. Methods contributed 36%, method-amputee and
occasion-amputee interactions contributed both 25% to the error variance.
CONCLUSIONS: Repeatability coefficient was lowest for the CAD hand scanner, which
indicates the best reliability. Substantial differences existed in stump volumes
measured between the 4 methods.
