As GIRD and posterior shoulder tightness is interrelated with each other and well documented in overhead athletes. Many studies have been reported to evaluate the acute effects of sleeper stretch in overhead throwers but no studies till now have been reported to evaluate the long-term effect in overhead throwers. And many studies also have shown that kinesiology tape also improving IR ROM of dominant shoulder to check the long-term effect of kinesiology tape. The present study is to compare the effect of sleeper stretch with and without Kinesio tape to improve the GIRD in overhead throwers. Methodology: 60 overhead throwers, no age limitation(male and female) were recruited from Nehru ground and Mangala stadium (Mangalore), and cricket academy in Vadodara(Gujarat) and SAI (sports authority of India) in Gandhinagar (Gujarat). 60 overhead throwers randomly divided into two groups. Group 1 (n=30) was received only sleeper stretch and group 2 (n=30) was received sleeper stretch and kinesiology tape. The modified sleeper stretch, per¬formed with the patient inside lying on the throwing side to stabilize the scapula against the table and both the shoulder and elbow flexed to 90°. In this position, passive IR is applied to the dominant arm by using the opposite hand. The immediate effects of the sleeper stretch, performed 3 times for 30 seconds, found an in¬crease IR ROM of the shoulder joint. Taping is done in sitting position. The first piece of the tape was applied from the anterior aspect of the humeral head, just lateral to the acromion process to finish at the inferior angle of the scapula. The second piece of tape commenced on the anterior aspect of the humeral head over the acromion. The opposite hand lifted the humeral head up and back during the application of the tape. Result: GIRD in overhead throwers between the group was analyzed using unpaired t-test comparison between the grips.by using the unpaired t-test. The mean diff between the 1st day to 1st week is 1.70 and t value is3.668, the mean diff between the 1st day to 2nd week is 4.56 and t value is 6.757, the mean diff between 1st day to 3rd week is 6.60 and t value is 7.51, the mean diff between 1st day to4th week is 6.96 and t value is 6.99,the mean diff between 1st week to 2nd week is 2.86 and t value is 7.05, the mean diff between 1st week to 3rd week is 4.90 and t value is 7.92,the mean diff between 1week to 4th week is 5.26 and t value is 6.69, the mean diff between 2nd week to 3rd week is 2.03 and t value is 4.92, the mean diff between 2nd week to 4th week is 2.40 and t value is 3.35, all above p<0.001means this is highly significant but the mean diff between 3rd week to 4th week is 0.367 and t value is 0.609,p<0.545 which is not highly significant. Conclusion: We concluded that the long-term effect of modified sleeper stretch showed improvement in IR ROM of the shoulder in the dominant side which is beneficial for athletes regular rehabilitation to prevent the injuries. The immediate effect of Kinesiology taping is better than long-term effect.
