Effect of a Multi-Air-Cushion Biofeedback Device (MABD) on Shoulder Muscles during the Dynamic Hug Exercise

چکیده
[Purpose] We developed a multi-air-cushion biofeedback device (MABD) to assist the dynamic hug exercise, and investigated the effects of MABD on the shoulder muscles during the dynamic hug exercise. [Subjects] Twelve males aged 22-32 years were recruited. [Methods] We measured the right side serratus anterior, lower trapezius, and upper trapezius muscle activities during the dynamic hug exercise with and without MABD. [Results] The serratus anterior and lower trapezius muscles activities significantly increased during the dynamic hug exercise with MABD compared to without it. The upper trapezius muscle significantly decreased during the dynamic hug exercise with MABD compared to without it. [Conclusion] The results suggest that the dynamic hug exercise with MABD is an effective scapular stability exercise.

متن کاملDurability Effects of Corrective Eexercise Program with Kinesiotaping and Physio Ball on EMG of Selected Shoulder Girdle Muscles in Boy with Upper Crossed Syndrome
Postural disorders disrupt muscle activity and lead to joint dysfunction. Maintaining the function of the shoulder joint requires precise coordination and on-time action of muscles, and its dysfunction lead to change in the level of muscle activity, movement disorder. This study aimed to measure the effects of corrective exercise program with kinesiotaping and physio-ball and durability of the...

Introduction: The use of exoskeletons as a new ergonomics intervention to reduce musculoskeletal disorders risk factors and increase human performance has emerged in the fourth-generation industrial revolution. The aim of this study was to assess the cervical exoskeleton effect on the neck and shoulder muscles electrical activity. Material and Methods: In this experimental study, 14 male parti...
متن کاملEffect of Selective Muscle Training Using Visual EMG Biofeedback on Infraspinatus and Posterior Deltoid
We investigated the effects of visual electromyography (EMG) biofeedback during side-lying shoulder external rotation exercise on the EMG amplitude for the posterior deltoid, infraspinatus, and infraspinatus/posterior deltoid EMG activity ratio. Thirty-one asymptomatic subjects were included. Subjects performed side-lying shoulder external rotation exercise with and without visual EMG biofeedba...
