ASSESSING TISSUE RESPONSE TO HIGH-VELOCITY THRUST MANIPULATIONS: MEASURING LASTING CHANGES IN C5-C6 FACET JOINT CAPSULE LENGTH WITH MUSCULOSKELETAL ULTRASOUND AND STIFFNESS WITH ELASTOGRAPHY
Florida Gulf Coast University
Summary
This study is a quasi-experimental study collected quantitative data , with a pre-test-post-test design. Pre-intervention, baseline measurements of C5-C6 right facet joint length and width with the head of the treatment plinth downward at 45 and 90 degrees, (relative to the rest of the table) and stiffness at 90 degrees, were taken prior to applying the long-axis thrust manipulation. Post-intervention measures were taken immediately after a long axis thrust manipulation of C5-C6 and again at 24-hours after the manipulation. The baseline pre-intervention measures were then compared to the post-intervention measurements. The investigator performing the manipulation was blinded to the quantitative measurements of the ultrasound images. The ultrasound operator was blinded to the outcome of the manipulation.
Description
The study takes place in Marieb Hall rooms 101 and 103 of Florida Gulf Coast University. After meeting the inclusion and exclusion criteria subjects sign the informed consent form described thoroughly on the following page. The participants undergo three recording sessions on two consecutive days. The first recording session consist of obtaining participant consent and general information, such as height and weight. The participants then has their baseline measures cervical flexion ROM, capsular length and width at both 45 and 90 degrees, and stiffness at 90 degrees, taken. The second and thir…
