Axial unloading therapy device for cervical spine rehabilitation

Area of Science:

• Orthopedics
• Biomedical Engineering
• Physical Therapy

Background:

• Chronic idiopathic neck pain necessitates innovative therapeutic solutions.
• Current treatments may not adequately address unloading the cervical spine in a neutral posture.
• A need exists for safe and effective cervical traction devices.

Purpose of the Study:

• To design and construct a prototype device for low-load cervical traction in an upright, seated position.
• To evaluate the safety and efficacy of the device and proposed outcome assessment methods.
• To investigate the biomechanical effects of cervical unloading.

Main Methods:

• Development of a prototype low-load cervical traction device.
• Assessment of the device using radiographic imaging, cervical range-of-motion, and electromyography (EMG).
• Testing on a cohort of normal subjects to evaluate device safety and measurement techniques.

Main Results:

• The prototype device safely transfers load to the occipital region.
• Low-load cervical unloading resulted in lateral spine rotation and posterior lengthening.
• The proposed outcome measurement methods were demonstrated as safe for potential patient application.

Conclusions:

• The designed cervical traction device is safe and effective for unloading the cervical spine.
• The study validates the use of radiographic, range-of-motion, and EMG methods for outcome assessment.
• The findings support the potential application of this device and methods in a clinical patient population.
