Treatment and study plan

Eccentric training

Other

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.

Concentric training

Other

Concentric 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.

Standard Physiotherapy

Other

The participants will receive standard physiotherapy. The standard physiotherapy exercises will be supervised by the physiotherapist, same as intervention exercises.
