Simultaneous Crepitus and Diagnostic Ultrasound Assessment of the Lumbar Zygapophyseal Joints Expansion of Validation and Reliability of Automated Analysis of Crepitus in Human Subjects
National University of Health Sciences
Summary
Chiropractic adjustment has been shown to gap certain joints in the spine, thereby improving mobility in individuals with decreased movement capabilities. During normal motion, joints in the spine produce sounds and vibrations called crepitus. The purpose of this study is to assess how this crepitus may be used as an indicator for joint degeneration in healthy human subjects and those with low back pain, and if chiropractic adjusting causes change in this crepitus. The investigators hypothesize that change in crepitus after adjustment may be a useful indication of changes in joint mobility and joint stiffness.
Description
Objective: This is an expansion of the initial study "Analysis of Crepitus in Human Subjects" to assess the feasibility of simultaneously recording zygapophyseal (Z) joint crepitus using piezoelectric accelerometers and Z joint motion using diagnostic ultrasound (US), and qualitatively assess the US images with particular focus on images taken of Z joints exhibiting crepitus. Like the original study (n=12), the results of a recently developed automated method (AM) is compared with two human observers in the analysis of recordings of human lumbar zygapophyseal (Z) joint crepitus. The recordings…

Interventions
- OtherRange of motion with spinal adjustment
With accelerometers affixed to spine recording vibrations, the participants complete range of motion. After completing, they receive a low back spinal adjustment and repeat range of motion
