Background and Objective: The shoulder joint is continuously under various pressures. Shoulder impingement syndrome is the most common problem. Stability of the shoulder is due to the interaction between static and dynamic stability which is caused through mediation of sensorimotor system (proprioception). This study was investigated to determine the effect of 6 weeks resistance training with elastic-band on proprioception in male athletes with shoulder impingement syndrome. Method: In this quasi-experimental study, 30 adult males with shoulder syndrome divided into control and interventional groups. Subjects in interventional group were received resistance exercises with elastic-band for six weeks. The shoulder joint proprioception, perior and at the end of study in 0, 45 and 90 angle were measured using isokinetic, Biodex System 3. Results: Significant improvement in the shoulder joint proprioception in 0, 45 and 90 angle were observed in interventional group in comparision with controls (P<0.05). Conclusion: Six weeks of resistance training with elastic-band improved shoulder joint proprioception of males with impingement syndrome.

Background and Objective: Proprioception an important role in shoulder joint function. Exercise and throat of the upper extremity are complex and skinny movements that apply a great deal of stress on the shoulder joint. This study was done to evaluate the relationship between proprioception and rotator muscles strength in dominant and non-dominant side with shoulder pain of wheelchair basketball athletes.
Methods: In this descriptive-analytic study, 50 wheelchair basketball athletes were selected in non-random sampling way from wheelchair basketball gyms from Alborz and Tehran in Iran. WUSPI, MMT system and repositioning error test with felexometere were used for assessment of shoulder pain, rotator muscles strength and proprioception respectively.
Results: There was a significant difference between dominant and non-dominant side rotators strength and proprioception (P<0.05). There was a significant relationship between internal rotators strength and proprioception in dominate side with shoulder pain (P<0.05). There was not a significant relationship between external rotators strength and proprioception in non-dominate side with shoulder pain.
Conclusion: Repeated pattern of movements in the wheelchair basketball athletes at the long time causes muscle imbalance in strength shoulder joint. It is known as a risk factor in shoulder injuries.
