Electromyographic Activity of Shoulder Muscles During Unilateral Upper Extremity Proprioceptive Neuromuscular Facilitation Patterns

摘要: Twenty-nine normal adults were tested to measure the electrical activity of anterior, middle, and posterior portions deltoid muscle sternal portion pectoralis major during performance four upper extremity diagonal patterns with elbow straight, flexing, extending. The performed through range motion, an isometric contraction in shortened range. With middle was primarily active shoulder flexion, abduction, external rotation; anterior adduction, extension, internal rotation. exhibited significantly greater their optimal strainght, followed by flexing less its pattern produced greatest straight or Findings confirm considered for monitored these two muscles subjects. Suggestions are made study patients who exhibit imbalances strength.
