영문 초록

The lower trapezius muscle is an important stabilizer and primary mover of the scapula. The potential use of ultrasound imaging to evaluate scapular muscle function warrants investigation. The purpose of this study is to use ultrasound imaging for determining the effectiveness of 4 different isometric exercises for maximally activating the lower trapezius muscles in healthy subjects. Twenty-eight (14 men and 14 women) volunteers were recruited for this study. Thickness measurements of the lower trapezius muscles were recorded during 4 exercises: latissimus pulldown (LP), prone V -raise (PV), prone row (PR), and modified prone cobra (JVIP). Lower trapezius muscle thickness was measured 3 times by 2 investigators at a point 3 cm lateral to the lateral edge of the T8 spinous process. The order of 4 exercise execution was randomized for each participant. To identify statistical significance, one-way ANOVA with repeated measures was used with the significance level of .05. Intraclass correlation coefficient (ICC) for intra -reliability was .86 ~ .98 and inter-rater reliability .83 ~.96 for the lower trapezius, respectively (p<.01) Thickness changes in the lower trapezius muscles between the relaxed and contracted states in men were as follows: LP (7.37: ±2.68 mm, 182%), MP (4.69: ±1.74 mm, 167%), PV (4.52: ±1.47 mm, 149%), and PR (3.84: ±1.72 mm, 133%). In women the values were as follows: LP (4.64: ±1.24 mm, 163%), MP (2.79: ±.81 mm, 131%), PV (2.78: ±.85 mm, 129%), and PR (2.21: ±1.26 mm, 100%). Thickness of the lower trapezius muscles significantly differed between exercises in both the gender (p<.01) The LP was the most effective exercise for increasing the activation of the lower trapezius muscle in both the gender. We recommend performing the LP exercise for strengthening the lower trapezius muscles.
