Description of intervention(s) / exposure
This particular study will require the participants to perform one of two stretches on the dominant side over a 3 weeks period . Participants will be taught the correct technique for performing the stretches by the investigator carrying out the measures. They will be instructed to hold the stretch for 30 seconds for 5 repetitions each session. Following this the therapist will inspect the performance of the stretch and ensure a correct technique .The stretch will be able to be performed on the floor,yoga mat or carpet /rug. Participants will be given an information sheet with instructions and pictures of the stretch and told to contact the researcher if they have any questions about the stretch during the study. Stretching is to be performed twice a day and it is recommended that this occur once in the morning and once in the evening before bed. Participants in both groups will be instructed to perform their respective stretches both morning and night, 7 days a week for 3 weeks. Before starting the stretch it is recommended to do some gentle warm up movements of the shoulder such as large slow circles of the arms.
The participant should perform 5 repetitions of the stretch in the morning and 5 repetitions in the afternoon.
1. Modified sleeper stretch - the participant should be lying on a firm surface (floor with yoga mat, carpet) on their dominant side, With their trunk rotated slightly backwards. Using the non-dominant arm, the participant gently should pull the forearm down to the floor until they feel the stretch at the back of their shoulder. The participant should not feel any pain with the stretch.
2. The participant positions him/her self in sitting with feet flat on the floor. He/she raises the dominant arm to 90 degrees of forward flexion. Using the non-dominant arm the participant pulls the throwing arm across the body towards the opposite shoulder as shown in the photo in the Instruction sheet. The stretch should be felt across the back of the shoulder.
Participants will be required to fill in a diary recording completion of the stretching program in the morning and at night. It will be made clear to the participants that accurate recollection is essential to the study and there will be no consequences for a lack of adherence to the stretching program.

Outcomes
Primary outcome [1] 298434 0
Measure of acromio-humeral distance with diagnostic ultrasound.

The participant will be seated and the ultrasound head placed on the anterior aspect of the shoulder in anterior -posterior direction ( Refer to Mc Creesh et al 2016)
Timepoint [1] 298434 0
All pre-measures - post screening and acceptance into the study and prior to teaching/demonstration of stretch
Post-measures - 3 weeks post stretch programme
Secondary outcome [1] 324124 0
ROM glenohumeral internal rotation (IR) at 90 degrees shoulder abduction.
The participant is positioned supine with dominant upper arm positioned at 90 degrees of abduction resting on the bed. A small folded towel will be placed under the upper arm to ensure the arm is level with the shoulder - not extended.
A digital inclinometer will be used to measure range of internal rotation (IR) of the dominant shoulder. This will be placed on the participant's forearm at the level of the lateral epicondyle. It will be held in place by a small piece of tape. an initial reading will be recorded.
Commencing at the mid point of IR/ER ( designated 90 degrees to the total range of IR will be measured.
The investigator will palpate the humeral head with one finger and the other finger will be placed on the coracoid process of the scapula. This point is considered to be the point when the scapula starts to move with the humeral head (i.e. the limit of glenohumeral IR. This measure will be repeated three(3) times and the range on the inclinometer recorded by an assistant

The other side will then be tested in the same manner.

Pre-measures - post-screening and acceptance into the study /pre teaching/demonstration of stretch
Post-measures at the end of the three (3) weeks stretching programme
Secondary outcome [2] 324125 0
Measure of shoulder horizontal adduction.
The participant will be seated with feet flat on the floor .He/she will be asked to lift the dominant arm to 90 degrees of flexion and then move the arm across their chest as far as possible to the point of a feeling of stretch in the posterior aspect of their shoulder. This range will be measured with a universal goniometer placed on the superior aspect of the shoulder with the movable arm aligned along the arm. This measure will be repeated three(3) times.
The other arm will then be tested for comparison
Timepoint [2] 324125 0
Pre- measures- Post screening and acceptance into the study /pre-teaching/demonstration of stretch.
Post-measures -at the end of the three (3) weeks stretching programme
