[PURPOSE] This study is a pilot study to investigate the possibility of kinect sensor based muscle strength test. [METHODS] Ten male subjects (age: 26.30±1.70 years, height: 176.88±2.89cm, weight: 73.40±4.03kg) were selected for the study. The exercise specialist and kinect sensor based muscle strength test program were evaluated at the same time. The items of evaluation were upper strength test (30 sec. arm curls) and lower strength test (30 sec. chair stands). Intraclass correlation coefficient (ICC) was calculated using a two-way mixed model to determine the reliability between the results measured by the exercise instructor and the results measured by the kinect sensor-based muscle strength test method. Bland-Altman plots were used to assess the differences between the two methods and to evaluate the agreement. To obtain the maximum and minimum values of the error intervals, mean + 1.96 × standard deviation and mean -1.96 × standard deviation were calculated. [RESULTS] As a result of upper strength test, ICC was 0.904 (95% CI: .614-.976), Bland-Altman analysis showed that the mean value of the result was 0.6 and the error interval was -3.44 to 4.64. As a result of the test of lower strength test, ICC was found to be 0.895 (95% CI: .576-.974), Bland-Altman analysis showed that the mean value of the result was -0.3 and the error interval was -3.50 to 2.90. [CONCLUSIONS] The ICC of the test showed very high inter - test reliability, showing no difference between the two methods. Therefore, kinect sensor-based muscle strength test may be recommended as a new objective method for testing the strength of the elderly.
