Differences in Muscle Activities of the Infraspinatus and Posterior Deltoid during Shoulder External Rotation in Open Kinetic Chain and Closed Kinetic Chain Exercises
[Purpose] This study investigated the changes in electromyographic (EMG) activities of the infraspinatus and posterior deltoid muscles during shoulder external rotation under open kinetic chain (OKC) and closed kinetic chain (CKC) exercise conditions. [Subjects] In total, 15 healthy males participated in this study. [Methods] Subjects performed shoulder external rotations under CKC and OKC cond...
متن کاملChanges in the electromyographic activities of the infraspinatus and posterior deltoid according to abduction angles of the shoulder joint during shoulder external rotation in closed kinetic chain exercise
[Purpose] This study's purpose was to identify abduction angles of the shoulder joint that can provide effective infraspinatus muscle exercises while minimizing the muscle activity of the posterior deltoid muscle. [Subjects and Methods] The subjects of this study were 15 healthy young students in their 20s. Subjects adopted a standing position and performed shoulder external abduction while pus...
متن کاملNormalized Electromyography of Shoulder Muscles during Selected Functional Tasks of Upper Limb in Patients with Shoulder Impingement Syndrome
Background & Aims: Precise muscle activity pattern is required to maintain normal shoulder function and any alteration in muscle activity can result in movement impairment. The purpose of this study was to assess normalized electromyography (EMG) of shoulder muscles during selected functional tasks of upper limb in patients with shoulder impingement syndrome. Methods: Test group consisted of 15...
متن کاملCombined Open and Closed Kinetic Chain Exercises for Patellofemoral
Patellofemoral pain syndrome (PFPS) is a common ailment of the knee. Both open and closed kinetic chain exercises are effective in strengthening of the quadriceps muscle. It has been suggested that these exercises are used jointly in the management of PFPS, but no study to date has evaluated the effect of combined open and closed kinetic chain exercises on PFPS. The present randomized controlle...
متن کاملOpen and closed kinetic chain exercises improve shoulder joint reposition sense equally in healthy subjects.
OBJECTIVE To compare the effects of open and closed kinetic chain exercise on shoulder joint reposition sense. DESIGN AND SETTING Subjects with no previous upper extremity injury participated in a 6-week exercise program consisting of 3 sessions per week. SUBJECTS Thirty-nine healthy male military cadets: 13 each in the open, closed, and control groups. MEASUREMENTS Each subject was prete...
