Investigation of the Effectiveness of Core Stabilization Training in Patients With Subacromial Impingement Syndrome
A study testing Core stabilization training and Standart Rehabilitation in people with Subacromial Impingement Syndrome, run by Bandırma Onyedi Eylül University at 1 site in Turkey (Türkiye).
Trial summary
Subacromial Impingement Syndrome (SIS) is one of the most common shoulder problems. The core region is considered a kinetic link that facilitates the transfer of torque and angular momentum between the upper and lower extremities during body movements. Read more about this study

About this study
Official title: Investigation of The Efficacy of Core Stabilization Training in Patients With Subacromial Impingement Syndrome: A Randomized Controlled Study
Subacromial Impingement Syndrome (SIS) is one of the most common shoulder problems. The core region is considered a kinetic link that facilitates the transfer of torque and angular momentum between the upper and lower extremities during body movements. The decrease in core stabilization affects both trunk control and the quality of extremity movements depending on the kinetic chain in the body. The improvement in core stabilization balances the load transfer between the trunk and the extremities and reduces the asymmetry between the extremities. Core stabilization training should be included in rehabilitation programs as core stabilization is adversely affected in patients with SIS. For this reason, this study was planned to examine the effects of core stabilization training applied in addition to conventional treatment in patients with SIS on pain, range of motion, shoulder muscles strenght and core stability.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Core stabilization trainingOther
First, while focusing on the activation methods of deep cervical flexor, transversus abdominus and multifidus muscles in individuals; In the next stages, exercises will be performed that will preserve the contraction of the deep cervical flexor, transversus abdominus and multifidus muscles and activate the other muscles of the body.
Standart RehabilitationOther
This treatment includes shoulder exercises and conventional therapy (Infrared, TENS).
| Study group | Role | What they receive |
|---|---|---|
| Core stabilization group | Experimental | Individuals included in this group will receive 20 minutes of core stabilization training in addition to 40 minutes of standard rehabilitation. Patients will be trained 5 days a week for first 3 weeks(standart rehabilitation + core stabilization training) then will be trained 3 days a week on 4-6 week (only core stabilization training). The next 6 weeks will be given a home exercise program including shoulder exercises and core stabilization training. Receives: Other: Core stabilization training; Other: Standart Rehabilitation |
| Control group | Other | Individuals included in this group will receive only 40 minutes of standard rehabilitation. Patients will be trained 5 days a week for first 3 weeks(only standart rehabilitation). The next 9 weeks will be given a home exercise program including shoulder exercises. Receives: Other: Standart Rehabilitation |

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Subacromial Impingement Syndrome (SIS) is one of the most common shoulder problems. The core region is considered a kinetic link that facilitates the transfer of torque and angular momentum between the upper and lower extremities during body movements. The decrease in core stabilization affects both trunk control and the quality of extremity movements depending on the kinetic chain in the body. The improvement in core stabilization balances the load transfer between the trunk and the extremities and reduces the asymmetry between the extremities. Core stabilization training should be included in rehabilitation programs as core stabilization is adversely affected in patients with SIS. For this reason, this study was planned to examine the effects of core stabilization training applied in addition to conventional treatment in patients with SIS on pain, range of motion, shoulder muscles strenght and core stability.

Test will be applied to assess the strength of the core muscles. The subjects are positioned in the prone position with their hands shoulder-width apart and elbows and knees flexed. The subjects were asked to raise their body up by extending their elbows. The number of times the patient repeats the movement in 30 seconds is recorded.
Sit-ups test
Time frame: Baseline
Test will be applied to assess the strength of the core muscles. The subjects are asked to flex the trunk while the knees are flexed in the supine position. During the test, the feet of subjects are stabilized. The number of times the patient repeats the movement in 30 seconds is recorded.
Sit-ups test
Time frame: 3 week
Test will be applied to assess the strength of the core muscles. The subjects are asked to flex the trunk while the knees are flexed in the supine position. During the test, the feet of subjects are stabilized. The number of times the patient repeats the movement in 30 seconds is recorded.
Sit-ups test
Time frame: 6 week
Test will be applied to assess the strength of the core muscles. The subjects are asked to flex the trunk while the knees are flexed in the supine position. During the test, the feet of subjects are stabilized. The number of times the patient repeats the movement in 30 seconds is recorded.
