The Effect of Adding Kinetic Chain Exercises to Routine Rehabilitation Protocol on the Muscle Activation Pattern, Shoulder Kinematics, Pain, Functional Abilities and Quality of Life after Rotator Cuff Tendons Repair

The effect of adding kinetic chain exercises to the routine rehabilitation protocol (ASSET) on the pattern of muscle activity and kinematics of the shoulder joint, pain, functional abilities and quality of life of people after shoulder rotator cuff tendon repair surgery

Clinical trial with test and control group, with parallel groups, single-blind, randomized, on 28 patients in which sealed envelopes were used for randomization

Immediately after the surgery, the participants undergo passive phase treatment for 6 weeks, same for everyone After 6 weeks, they are divided into two test and control groups by randomization method and in a blind way. The first same assessment session for both groups is done, which includes assessment of SHR, EMG and AROM of shoulder elevation by motion analysis system, measurement of PROM of shoulder by goniometer, pain assessment by VAS, DASH and SF-36 quality of life questionnaire are filled Then both groups enter the second phase of 4 weeks treatment, which is based on ASSET protocol The test group, in addition to the mentioned treatment received the kinetic chain exercises program as therapeutic intervention Finally, the second assessment session is conducted in both groups, similar to the first session

Patients with partial supraspinatus tendon tear underwent arthroscopic tendon repair surgery

The control group is treated with routine rehabilitation protocol (ASSET) The test group, in addition to the treatment of the control group, also performs kinetic chain exercises

People are divided into two test and control groups by randomization method with sealed envelopes. In this way, the control and test words (14 each) are written on the cards according to the number of the studied sample and each one is put in an envelope and the envelopes are sealed. Then, each patient who enters the study randomly chooses one envelope from the total envelopes and is placed in one of the two test or control groups. In the same way, this work will continue until the end of the sample size of the study.

In this study, only the participants who are patients after shoulder rotator cuff tendon repair surgery are kept blind, so that first the study procedures are fully explained to the participants and the study groups are introduced to them in detail, but after their consent In order to participate in the study, in the stage of determining the group, the patients are randomly assigned to the test and control groups without knowing their group. Both groups do common exercises, and people in the test group do more exercises under the name of kinetic chain exercises. Since the therapist, evaluator and analyst is a researcher, she cannot be kept blind. In addition, in order to comply with ethical issues, after the end of the study, the control group will also receive additional treatment of the intervention group
