Abstract:
ObjectiveTo test the inter-tester reliability and test-retest reliability of MyotonPRO for evaluating neck and shoulder muscle performance parameters in patients with unilateral chronic neck pain, observe the difference of muscle performance between the healthy and affected sides of patients with chronic neck pain, and analyze the factors that cause the imbalance of muscle performance in patients with chronic neck pain. MethodsFrom January to June, 2023, 32 patients with unilateral chronic neck pain in Guangdong Second Traditional Chinese Medicine Hospital were selected. Two testers used the same MyotonPRO equipment to measure the muscle tone, muscle hardness and muscle elasticity on both sides of the sternocleidomastoid muscle and the upper trapezius muscle in the relaxed position. Tester 1 repeated the measurement after an interval of 30 minutes, and Tester 2 was measured within the time interval between the two measurements of Tester 1. The intraclass correlation coefficient (ICC), standard error of mean (SEM) and minimum detectable change (MDC) were calculated simultaneously. The measurement results were plotted into Bland-Altman diagram and systematic bias analysis was performed. The difference in muscle characteristics between the affected side and the healthy side was compared. At the same time, the Visual Analogue Scale (VAS) score and body mass index (BMI) of the subjects were collected for correlation analysis. ResultsExcept the sternocleidomastoid muscle elasticity of the affected side (ICC = 0.697), the inter-tester reliability of all other parameters was high to very high (ICC = 0.719 to 0.952, SEM = 0.04 to 6.53, MDC = 0.12 to 18.11). The test-retest reliability of all parameters was high (ICC = 0.883 to 0.981, SEM = 0.03 to 5.72, MDC = 0.09 to 15.84). Bland-Altman plot analysis showed that the scatter distribution was consistent. The muscle tone, muscle hardness and muscle elasticity of sternocleidomastoid muscle and upper trapezius muscle were higher on the affected side than on the healthy side (t > 2.846, P < 0.05). The asymmetry index of tension, hardness and elasticity of upper trapezius muscle and sternocleidomastoid muscle was significantly positively correlated with VAS score and BMI (r > 0.385, P < 0.05). ConclusionMyotonPRO has good inter-tester reliability and retest reliability in evaluating the muscle performance of both sides of patients with chronic neck pain. The muscle tone, muscle hardness and muscle elasticity of sternocleidomastoid muscle and upper trapezius muscle on the affected side were higher than on the healthy side, and the difference of muscle performance was positively correlated with pain and BMI.
