Comparison of the effects of forward and reverse serratus anterior muscle therapeutic exercises on electromyographic activity and static and dynamic position of scapula in scapular dyskinesis
Comparison of the effect of forward and reverse therapeutic exercises of the serratus anterior muscle on the position of the scapula electromyographic activity of this muscle
Design
Clinical trial with two intervention groups, parallel groups, single-blind, randomized, 24 participants, randomization is done using concealed envelopes.
Each of the participants is required to choose randomly from two concealed envelopes (forward group or reverse group). According to the selected envelope, the group of people is determined.
Settings and conduct
The location of the study is the Motion Analysis Laboratory of Tarbiat Modares University.
In order to record the electrical activity of the muscles and the position of the scapula, the Mayon electromyography device and the Vicon motion analysis device are used.
The study is a randomized single-blind. In this way, the participants choose one of the closed envelopes and hand it to the researcher without looking inside. The researcher is not blind and is aware of the groupings and interventions.
The participants are evaluated at the beginning and in the next stage they are treated for 3 weeks according to the program. Finally, in order to check the effects of the intervention, they are re-evaluated.

Intervention groups

Description
Intervention group: Participants in the first group are given reverse serratus anterior exercises. The exercises in the first group are performed without applying any external forces, such as weights, Thera bands, etc. The progress of the exercises in the first group will happen by increasing the repetition of the exercises and increasing the hold time. At the beginning of the exercises, the number of repetitions of each exercise is 6 times per session and hold for 2 seconds each time, which eventually reaches 10 times and holds for 10 seconds each time with the progress of the treatment program. Training sessions start with 3 sets, and in order to comply with the principle of overload, 2 sets are added to the number of previous sets at the beginning of each week. The number of training sessions is 3 times a day and the duration of the treatment period is 3 weeks. How to perform exercise 1: To perform this exercise, we ask the person to place the upper limb in 90 degrees of abduction and 45 degrees posterior to the frontal plane and take fixed surface. After ensuring the correct positioning of the upper limb, the person is taught to rotate the trunk to the involved side while keeping the head and neck stable and looking at a fixed point at eye level on the opposite wall. Move sternum upwards and do a deep inhale and exhale at the same time. How to perform exercise 2: To perform this exercise, while the upper limb is placed next to the body and in anatomical position, both upper limbs should be extended by 30 degrees and take a fixed surface, and at the same time, while the head and neck are fixed and He looks at the opposite wall at a fixed point at the level of the eyes, moves the sternum upwards and simultaneously inhales and exhales deeply. How to do exercise 3: To do this exercise, the person is taught to keep his head and neck fixed when the upper limb is at 130 degrees of abduction and take a fixed surface and look at a fixed point at the level of the eyes. Then while moving the sternum upwards and rotating the trunk to the affected side, inhale and exhale deeply at the same time.

Description
Intervention group: Participants in the second group are given Forward Serratus Anterior exercises. The exercises in the second group are performed without applying any external forces, such as weights, Thera bands, etc. The progress of the exercises in the second group will happen by increasing the repetition of the exercises and increasing the hold time. At the beginning of the exercises, the number of repetitions of each exercise is 6 times per session and hold for 2 seconds each time, which eventually reaches 10 times and holds for 10 seconds each time with the progress of the treatment program. Training sessions start with 3 sets, and in order to comply with the principle of overload, 2 sets are added to the number of previous sets at the beginning of each week. The number of daily training sessions is 3 times and the duration of the treatment period is 3 weeks. How to perform the Dynamic hug plus exercise: To perform this exercise, the shoulders should be in 60 degrees of abduction and the elbows should be in 45 degrees of flexion. Then the arms are moved forward and inward. When the arms are straight in the midline, the person is asked to move their arms further forward with an additional force. How to perform Wall slide exercise: To perform this exercise, a person must stand facing the wall and put his forearm and elbow in contact with the wall while the upper limbs are shoulder width apart. Then the person is asked to raise his hands slowly with the help of the wall up to about 150 degrees and bring them back. How to perform Side-lying forward flexion: To perform this exercise, the person is side-lying and raises his arm from the side of the trunk to the end of the flexion range of motion.
