Comparison of therapeutic effects of mobilization and mobilization with movement on acromiohumeral distance in athletes with shoulder primary impingement syndrome: A randomized clinical trial

Comparison of therapeutic effects of mobilization and mobilization with movement on acromiohumeral distance in athletes with shoulder primary impingement syndrome

This is a randomized clinical trial study with parallel groups, will be conducted on 51 athletes with shoulder primary impingement syndrome. Assignment of patients to study groups is in the form of random blocking.

From athletes with confirm diagnosis of shoulder primary impingement syndrome referring to Tabatabai Clinic, Semnan, total of 51 patients will be selected and randomly divided into 3 groups.

Inclusion criteria: Age between 20to 35 years, semi-professional athletes (who exercise an average of 3 to 6 hours per week), doing overhead exercises such as volleyball, primary impingement syndrome of shoulder, patient consent to participate in the study; Exclusion criteria: History of trauma, fracture, dislocation or surgery in the neck and shoulders, osteoporosis, tumor or neuromuscular disorders around the shoulder, any subcutaneous inflammation, inflammatory disorders such as rheumatoid arthritis, adhesive capsules, complete rupture of the rotator cuff tendon, corticosteroid injections in shoulders in the past year, received physical therapy for the shoulder or spine in the last 3 months

The first group undergoes mobilization for 6 sessions (3 times a week)Each technique is performed 4 times (30 seconds each). The second group undergoes mobilization with movement( MVM) for 6 sessions (3 times a week).Each treatment session consists of three sets of 10 repetitions and each repetition takes 4 seconds. The third group (control) does not receive any intervention.

Acromiohumeral distance, Shoulder Pain and Disability Index (SPADI), shoulder Range of motion (ROM) and pain severity

.In this study, we use the randomized permutation block method for random assignment. The operation will be as follows: three and six blocks with a combination of A (mobilization), B (motion mobilization) and C (control) will be the criteria. Depending on the different combinations, each of the blocks is assigned a number as follows: Block 1: BCAACB Block 2: BAACCB Block 3: ABC Block 4: ACBCAB Block 5: CBABCA Block 6: ABBCAC Block 7: ABBACC Block 8: ACBBAC Block 9: CBA Block 10: ABCACB Using a table of random numbers, considering the numbers 1 to 9 in the unit and considering the number zero as the tenth block, select the order of the blocks and how to assign patients to one of the groups A, B or C according to the selected blocks of the face. Takes. After preparing a randomization list for each patient, they will have a number in the order of enrollment (from 1 to 51). A sealed envelope is provided with A, B, or C written inside the envelope based on the compiled list. The researcher who does not know the main list, after registering the person entered to study and check the number of the person, opens the relevant envelope and realizes the type of intervention based on the contents of the envelope.In this way, the researcher realizes the type of intervention only after the patient enters the study and determines her eligibility, by opening the envelope, and finally we will have three balanced groups.

Participants are divided into three groups by general matching and randomly using random and double-blind blocking methods. Participants and evaluators do not know the division. All evaluations and measurements of the results are performed by an experienced person who has no knowledge of grouping individuals. The control group will receive each of the desired treatments within two weeks of their choice.
