简要总结
The investigators hypothesize that neuromuscular realignment of the pelvis bones will be more effective in improving range of motion and torque production at the shoulder joint than traditional exercises for improving hip internal rotation and adduction range of motion.
详细描述
Current literature shows a relationship between hip joint flexibility and shoulder range of motion and torque production in athletes and the general population. It is well established that limited hip joint internal rotation and adduction, specifically in baseball players, results in limited trunk rotation during pitching phase of throwing. Due to restricted rotation range at the hip joint, athletes try to compensate for the diminished rotational momentum of the trunk by producing excessive external rotation at the shoulder joint during the cocking phase of throwing. Such compensation results in laxity and overstressed shoulder joint structures. In the long term, increased laxity of the joint affects normal muscle mechanics and results in decreased torque production at the shoulder joint.
The investigators hypothesize that neuromuscular realignment of the pelvis bones will be more effective in improving range of motion and torque production at the shoulder joint than traditional exercises for improving hip internal rotation and adduction range of motion.
Group assignment:
An equal number of male and female subjects will be randomly assigned into one of three groups:
Group one will have standard treatment for improving hip range of motion. Group two will receive the new neuromuscular approach for improving pelvic alignment.
