A Study Of Sonographic Assessment Of Intervertebral Cervical Motion During Seated Self-Cervical Traction

Overview

About this study

The purpose of this study is to use ultrasound imaging to quantify changes in interspinous process distance (ISPD) across the lower cervical spine during three seated conditions: neutral rest, cervical flexion, and cervical flexion with self-cervical traction; is to determine whether self-cervical traction produces measurable segmental distraction beyond cervical flexion alone, thereby helping characterize the biomechanical effects of self-traction and inform future clinical prescription.
