OH c CS flexionThe overhead reach assessment examines the strength of the Anterior Fascial Line (Anatomy Trains) as well as the length of the Posterior Fascial and Posterior Functional Lines.

Cervical pain
Thoracic pain
Shoulder pain
Lumbar pain

The most prevalent finding involves a decrease in length of the thoracolumbar fascia and/or the latissimus dorsi will lead to decreased shoulder flexion with compensatory lumbar extension.

When assessing fascial lines, a weakness in one region will lead to a compensation in another region. In the image, the patent displays weak rectus abdominis muscles which lead to the lumbar hyperextension. She attempts to compensate and use her sternocleidomastoid (cervical flexion) to tension her anterior fascial line.

This is why we often see individuals flex their necks when trying to do sit-ups.
