Investigation of the Effectiveness of Core Stabilization Training in Patients With Subacromial Impingement Syndrome

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.

Treatment and study plan

Core stabilization training

Other

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.
