| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Eccentric training group | Experimental | The participants in this group will actively perform eccentric phase of resistive shoulder exercises. Additionally they will receive standard physiotherapy. |
|
| Concentric training group | Experimental | The participants in this group will actively perform concentric phase of resistive shoulder exercises. Additionally they will receive standard physiotherapy. |
|
| Control group | Active Comparator | The participants in this group will receive only standard physiotherapy. |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| 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. |
