Overview

Core stability is the ability to control the position and movement of the trunk for optimal production, transfer, and control of forces in the upper and lower extremities during functional activities.

Studies have shown that TrA activation is delayed in individuals with low back pain. The relationship between core stability and the lower extremity has been frequently studied in the literature, and according to Kibler's 'Kinetic Chain' theory, loss of proximal stability is known to lead to dysfunction in distal segments; however, the relationship between the upper extremity and core stability is still unclear. The aim of our study is to investigate the upper extremity reach capacity and scapular stability of individuals with low back pain in relation to TrA involvement and to compare them with healthy individuals without low back pain.
