Abstract
BackgroundScapular upward rotators are important for the ideal movement pattern of the glenohumeral joint. The Y-raise exercise (YR) can be recommended for the activation of these muscles overall and selectively for the lower trapezius (LT).ObjectiveThis study investigated and compared the activity of scapular upward rotators and activity ratios among three different Y-raise exercises (YR1, YR2, and YR3).MethodsFifteen healthy male individuals participated. All participants performed three different Y-raise exercises in random order: YR1, YR2, and YR3. Muscle activity of the upper trapezius (UT), LT, and serratus anterior (SA) was measured during each exercise using surface electromyography. Comparisons were analyzed by one-way repeated measures ANOVA, followed by Bonferroni adjustment.ResultsUT activity decreased in YR2 (23.21%) compared to YR1 (46.54%) and YR3 (42.95%) (p = 0.001). LT activity increased in YR3 (58.32%) compared to YR1 (46.44%) and YR2 (47.96%) (p = 0.001). The LT/UT activity ratio was higher in YR2 (2.57) compared to YR1 (1.14) and YR3 (1.74) (p = 0.001).ConclusionYR2 and YR3 can be recommended for selective LT activation in early-stage rehabilitation and overall scapular upward rotator activity in late-stage rehabilitation, respectively.
期刊介绍:
The Journal of Back and Musculoskeletal Rehabilitation is a journal whose main focus is to present relevant information about the interdisciplinary approach to musculoskeletal rehabilitation for clinicians who treat patients with back and musculoskeletal pain complaints. It will provide readers with both 1) a general fund of knowledge on the assessment and management of specific problems and 2) new information considered to be state-of-the-art in the field. The intended audience is multidisciplinary as well as multi-specialty.
In each issue clinicians can find information which they can use in their patient setting the very next day.
