详细描述
To examine and compare the effect of a novel stretching technique and traditional stretching on glenohumeral range of motion, strength, maximum voluntary contraction, pain, and subject satisfaction in overhead athletes with glenohumeral internal rotation deficits through a randomized clinical study. The investigators hypothesize that this type of novel intervention will help subjects with GIRD to restore range of motion, experience less pain and maintain the strength and motor unit recruitment following the novel intervention. This will help us to assess the potential beneficial effect of such intervention and to fill the gap in knowledge and help health care professionals to adequately select the right treatment modality.

入选标准
- •Participants must be between the age of 18 and
- •Perform overhead sports activities in the past 3 months.
- •Participants are required to display ≥ 20° less glenohumeral internal rotation ROM in their dominant shoulder compare to the non- dominate shoulder.
- •Participants will be included with or without pain during shoulder activities.
排除标准
- •Will exclude participants who are still recovering from previous surgery of the shoulder and elbow complex in the past 3 months, and currently receiving medical intervention for the shoulder.
研究组 & 干预措施
Novel Stretching Technique
Participants will perform the novel stretch in a supine position. Participants will place a small ball between their knees and squeeze the ball. Participants will be then bridge as high as possible . Participants will then flex their shoulder and elbow to 90°, and actively rotate to the end of ROM. Participants will use the other hand to push to the point of mild discomfort and simultaneously maintain contraction while progressing the stretch.
干预措施: Stretching (Procedure)
Traditional Stretching Technique
Participants will perform the modified sleeper stretch in a side-lying position on the side of the throwing shoulder with the throwing shoulder and elbow flexed to 90° . The participants will be instructed to allow the throwing shoulder to naturally fall into internal rotation to the end ROM where resistance will be felt . The participants will be then instructed to use the non-throwing hand to push the throwing shoulder into further internal rotation to the point of mild discomfort by applying pressure at the area of the wrist joint.
