영문 초록

Background: The maximum voluntary contractile strength (MVCS) and sustained time at 50% submaximal voluntary contractile strength (SMVCS) using a pressure biofeedback unit have been used to measure the muscle strength and endurance of deep neck flexor muscles. However, to date, there has been no test-retest reliability study for this measurement method. Objectives: The purpose of this study was to measure the test-retest reliability of muscle strength and endurance of deep neck flexor using a pressure biofeedback unit, with and without visual feedback. Methods: Thirty healthy subjects were recruited for this study. Muscle strength and endurance of deep neck flexor were measured by pressure biofeedback unit and stopwatch. Intra-rater reliability of the deep neck flexor strength and endurance was analyzed using intraclass correlation coefficients (ICC 3, 1). Furthermore, the paired t-test was used to compare the sustained time of SMVCS of deep neck flexor between with and without visual feedback. Results: For MVCS, the value of ICC with (ICC: 0.965) and without visual feedback (ICC: 0.892) were both excellent. For the sustained time of SMVCS, the value of ICC with visual feedback were excellent (ICC: 0.910) while without visual feedback was fair to good (ICC: 0.654). Additionally, the sustained time of SMVCS of deep neck flexor was significantly greater with visual feedback than without visual feedback (p < 0.05). Conclusions: The measurement of strength and endurance using a pressure biofeedback unit with visual feedback can be recommended for reliable measurement of deep neck flexor muscle. Furthermore, the pressure biofeedback unit with visual feedback may be an effective method to increase the endurance of deep neck flexor muscles.
