N2  - Back ground: cross education effect transfer is a well-known phenomenon that  unilateral training produces an increase in strength of the contralateral untrained muscle group. The purpose of thecurrent study was to investigate the effect of hand grip training on the electromyographic activity of the contra lateral rotator cuff in normal individuals. Subjects Thirty subject from both sexes (15 female and 15 male) with age ranged from 25 to 30 were participated in present study. All subjects were apparently normal with mean age of 27.53 ± 0.34 and mean BMI of 29.40 ± 2.48 kg/ m2.Design of the study: Pre test Post test design.Methods:Electromyographic activity of supraspinatus (SSP) and infraspinatus (ISP) muscles in non-dominant limb were assessed by electromyography (EMG) at these different angles (30{u00BA}, 60{u00BA}, 90{u00BA}) of shoulder abduction pre and post hand grip training by Hand Grip Squeezer Tool for 30 minutes.  Results:The result revealed a significant increase inelectromyographic activity (EMG) of both supraspinatus and infraspinatus muscles at different angles (30{u00BA}, 60{u00BA}, 90{u00BA}) of shoulder abduction in both limbs post-training in relation to pre-training. No significant differences were detected in between the three angles 30{u00BA}, 60{u00BA}, and 90 {u00BA} with regard to the EMG activity of infraspinatus muscles. Regarding supraspinatus muscles, there was asignificant difference in between angles, where angle 60{u00BA} was significantly higher than angle 90{u00BA}.Conclusion:These results revealed increase in EMG activity (amplitude, Root Mean Square RMS) of contralateral rotator cuff after hand grip exercise of ipsilateral limb
