Résumé
Test-retest reliability has not been previously reported for the instrumented modified Clinical Test of Sensory Interaction on Balance (i-mCTSIB) utilizing the Neurocom Very Simple Rehab (VSR) Sport force plate. The VSR Sport is a portable, relatively inexpensive force plate system utilized to assess postural stability in various populations. Therefore, the purpose of this study is to determine the test-retest reliability, standard error of measurement (SEM), and minimal detectable change (MDC) of the i-mCTSIB when assessed using the VSR Sport in a sample of healthy, older adults. This was a methodological study with 20 healthy, older adults between the ages of 65 and 85 years. Participants were tested twice in a single session on the i-mCTSIB utilizing the VSR Sport force plate. The mean sway velocity (°/s) measurements for the 2 trials were compared for each test condition to compute intraclass correlation coefficients (ICCs) for each measurement. Standard error of measurements and minimal detectable change at the 90% confidence level (MDC90) were also calculated. The test-retest reliability for each of the test conditions ranged from 0.762 to 0.909, which can be broadly interpreted as good-to-excellent reliability. The ICC(2,k) value of 0.898 for the composite score can also be interpreted as excellent reliability. Our results revealed small SEM for all test conditions (SEM = 0.060-0.101) except for the foam surface, eyes closed condition, with an SEM of 0.481. The MDC90 results for all testing conditions ranged from 0.140 to 0.285 except for the foam surface, eyes closed condition, which had an MDC90 = 1.12. The i-mCTSIB measurements utilizing the VSR Sport demonstrated good-to-excellent test-retest reliability. The clinical relevance of this study is that it demonstrates that the VSR Sport is a feasible alternative to other more expensive computerized systems used for the assessment of postural sway. MDC90 scores allow interpretation of change in i-mCTSIB scores following intervention. Practice effects may have contributed to the larger MDC90 for sway scores in the foam surface, eyes closed condition.

BACKGROUND AND PURPOSE
Test-retest reliability has not been previously reported for the instrumented modified Clinical Test of Sensory Interaction on Balance (i-mCTSIB) utilizing the Neurocom Very Simple Rehab (VSR) Sport force plate. The VSR Sport is a portable, relatively inexpensive force plate system utilized to assess postural stability in various populations. Therefore, the purpose of this study is to determine the test-retest reliability, standard error of measurement (SEM), and minimal detectable change (MDC) of the i-mCTSIB when assessed using the VSR Sport in a sample of healthy, older adults.
METHODS
This was a methodological study with 20 healthy, older adults between the ages of 65 and 85 years. Participants were tested twice in a single session on the i-mCTSIB utilizing the VSR Sport force plate. The mean sway velocity (°/s) measurements for the 2 trials were compared for each test condition to compute intraclass correlation coefficients (ICCs) for each measurement. Standard error of measurements and minimal detectable change at the 90% confidence level (MDC90) were also calculated.
RESULTS AND DISCUSSION
The test-retest reliability for each of the test conditions ranged from 0.762 to 0.909, which can be broadly interpreted as good-to-excellent reliability. The ICC(2,k) value of 0.898 for the composite score can also be interpreted as excellent reliability. Our results revealed small SEM for all test conditions (SEM = 0.060-0.101) except for the foam surface, eyes closed condition, with an SEM of 0.481. The MDC90 results for all testing conditions ranged from 0.140 to 0.285 except for the foam surface, eyes closed condition, which had an MDC90 = 1.12.
CONCLUSIONS
The i-mCTSIB measurements utilizing the VSR Sport demonstrated good-to-excellent test-retest reliability. The clinical relevance of this study is that it demonstrates that the VSR Sport is a feasible alternative to other more expensive computerized systems used for the assessment of postural sway. MDC90 scores allow interpretation of change in i-mCTSIB scores following intervention. Practice effects may have contributed to the larger MDC90 for sway scores in the foam surface, eyes closed condition.
