Arms and Interventions

Arm	Intervention/Treatment
Experimental: Eccentric training group The participants in this group will actively perform eccentric phase of resistive shoulder exercises. Additionally they will receive standard physiotherapy.	Other: Eccentric training Eccentric phase of resistive shoulder exercises will be performed three sets of 15 repetitions once a day for 12 weeks using therabands. Participants will be supervised by the physiotherapist 3 days a week for the first 6 weeks, 2 days a week for the next 3 weeks and 1 day a week for the last 3 weeks. Other: Standard physiotherapy The participants will receive standard physiotherapy. The standard physiotherapy exercises will be supervised by the physiotherapist, same as intervention exercises.
