Abstract
PURPOSE: The purpose of this study was to assess the reliability and validity of the ACEMFEI test (assessment of coordination, balance, gait and lower extremity strength) using both a quantitative and qualitative approach in individuals older than 65 years.
METHODS: Reliability: 10 subjects (8F-2M, 83.4±4.5yrs) undertook the ACEMFEI test twice. To assess inter-rater reliability, three investigators timed the two trials using a stopwatch (quantitative). To assess the agreement between the three investigators the coefficients of reliability (CR), intra-class correlation coefficients (ICC) and limits of agreement were determined for the total time to do the test (TT). Validity: 60 subjects (51F, 9M, 74.2±4.9yrs) were divided into four groups: (1) sedentary with previous history of falls, (2) sedentary without history of falls, (3) active with history of falls, and (4) active without history of falls. All of them undertook the ACEMFEI test once. One investigator undertook the timing and completed the assessment questionnaire (AQ) as a qualitative evaluation.
RESULTS: Reliability study. CR values for the TT were above 98% and with ICC of TT=0.999. The differences in TT between the three investigators' measures ranged from 0.19-0.55s SD of the mean difference. Validity study. Significant differences (p<0.05) were noted between the mean score of TT of group 4 and the rest of the groups, and between group 2 and 1 (group 1: 39.19±4.28s; group 2: 33.61± 3.46s; group 3: 35.10±3.73s; group 4: 27.65±4.41s). Significant differences were noted between the mean score of points obtained in the AQ of group 1 and the rest of the groups (group 1: 9.40±1.35; group 2: 12.87±1.19; group 3: 12.73±1.10; group 4: 14.13±1.92). In the multiple linear regression model for the TT, group 2 showed a drop of 5.68s with respect to the baseline (group1) over the TT; group 3 showed a decrease of 5.89s; and group 4 a decrease of 11.18s. In the model for the AQ, group 2 showed an increase of 3.39 points with respect to the baseline over the total points in the AQ; group 3 an increase of 3.46 points; and group 4 an increase of 4.59 points. R2 values of both models were 0.63 and 0.53, respectively.
CONCLUSIONS: The ACEMFEI test demonstrated good inter-tester reliability, internal consistency and concurrent validity from both a quantitative and qualitative perspective
