Exercises for biceps disorders and SLAP lesions
Although a lot of research has been done seeking to determine the exercises targeting scapular muscles and the rotator cuff most effectively, only little evidence is available on activation levels of the biceps during rehabilitation exercises. This study employed surface EMG to determine the activity of the biceps, the scapular and the glenohumeral muscles in frequently used exercises. On top of that, a ranking was set based on biceps activity, to acquire a progression in exercises for the rehabilitation of biceps related shoulder pain.
Exercises targeting the trapezius muscles only elicited low activation levels in the biceps, while activation levels in the biceps were higher for serratus anterior exercises. External rotation exercises showed slightly higher biceps activation levels than exercises for internal rotation. As expected, exercises specifically aimed at the biceps had the highest levels of activation.
During this study, only low to moderate activation was found in the biceps. Therefore, this progression of exercises should be used early in rehabilitation. Moreover, apart from activation levels, mechanical loads placed on the biceps should also be considered when selecting appropriate exercises. > From: Cools et al., Am J Sports Med 42 (2014) 1315-1322.
