| Abstract: | [Purpose] We developed a multi-air-cushion biofeedback device (MABD) to assist thedynamic hug exercise, and investigated the effects of MABD on the shoulder muscles duringthe dynamic hug exercise. [Subjects] Twelve males aged 22–32 years were recruited.[Methods] We measured the right side serratus anterior, lower trapezius, and uppertrapezius muscle activities during the dynamic hug exercise with and without MABD.[Results] The serratus anterior and lower trapezius muscles activities significantlyincreased during the dynamic hug exercise with MABD compared to without it. The uppertrapezius muscle significantly decreased during the dynamic hug exercise with MABDcompared to without it. [Conclusion] The results suggest that the dynamic hug exercisewith MABD is an effective scapular stability exercise.Key words: Biofeedback, Dynamic hug exercise, Scapular stability |
