Brief 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. 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.

QuickDASH
It is a questionnaire that evaluates disorders in all upper extremity functions. The QuickDASH is an abbreviated 11-question subset from the original Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire. The questionnaire's answers are scored on a 1-5 points scale that is then transformed to result in a score that ranges from 0 (indicating least disability) to 100 (indicating most disability).

Study Arms (2)
Core stabilization group
EXPERIMENTALIndividuals 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.
Control group
OTHERIndividuals 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.
Interventions
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.
This treatment includes shoulder exercises and conventional therapy (Infrared, TENS).
