Objective: Neck pain is a prevalent musculoskeletal (MSK) complaint and costly societal burden. Doctors of chiropractic(DCs) provide manual therapies for neck pain patients to relieve discomfort and improve physical function. Manual cervical distraction (MCD) is a chiropractic procedure for neck pain. During MCD, the patient lies face down on a specially designed chiropractic table. The DC gently moves the head and neck in a cephalic direction while holding a gentle broad manual contact over the posterior neck, to create traction effects. MCD traction force profiles vary between clinicians making standardization of treatment delivery challenging. This paper reports on a bioengineering technology developed to provide clinicians with auditory and graphical feedback on the magnitude of cervical traction forces applied during MCD to simulated patients during training for a randomized controlled trial (RCT). Methods: The Cox flexion-distraction chiropractic table is designed with a moveable headpiece. The table allows for long axis horizontal movement of the head and neck, while the patient's trunk and legs rest on fixed table sections. We instrument-modified this table with three-dimensional force transducers to measure the traction forces applied by the doctor. Motion Monitor software collects data from force transducers. The software displays the magnitude of traction forces graphically as a function of time. Real-time audible feedback produces a steady tone when measured traction forces are <20N, no tone when forces range between 20-50N, and an audible tone when forces exceed 50N. Peer debriefing from simulated patients reinforces traction force data from the bioengineering technology. Results: We used audible and graphical feedback to train and certify DCs to apply traction forces to the cervical spine of simulated patients within three specific ranges. This technology supports a RCT designed to assess the ability of clinicians to deliver MCD within specified force ranges to patients randomized to different force dosages as an intervention. Future applications may include training chiropractic students and clinicians to deliver the MCD treatment. Copyright © 2013 by ASME.
