필라테스 기구 운동 시 포지션에 따른 손목 과신전 자세가 상지와 어깨 근 활성도 및 통증에 미치는 영향

Abstract

Purpose: This study compares and analyzes the effects of wrist hyper-extension posture on muscle activity and pain in upper limbs and shoulders when applying the Pilates exercise program to healthy adult women.BR Methods: The participants repeated hyper-extension posture and neutral posture of the wrist three times each using three instruments (cadillac, reformer, barrel). The activities of upper limbs muscles (post deltoid, anterior deltoid, lateral triceps, biceps brachii, and extensor carpi radialis brav is) were measured using surface electromyography. The pains of upper limbs (median wrist, lateral wrist, lateral elbow, and upper shoulder) were measured using electro algometer (FPX25).BR Result: The hyper-extension posture of the wrist revealed significant differences activities of post deltoid, lateral triceps, biceps brachii and extensor carpi radialis bravis muscles compared to neutral position of the wrist (p.05).BR The hyper-extension posture of the wrist elicited pain on median wrist, lateral wrist, lateral elbow, and upper shoulder more earlier that neutral posture of the wrist significantly (p.05).BR Conclusion: The hyper-extension posture of the wrist during the Pilates exercise program can reduce muscle activities and elicited pain on the upper limbs. Neutral posture of the wrist is important to improve muscle activities and reduce pain.
