A Novel Device for Neck Pain in Active-duty Military Personnel With Forward Head Posture.

Safety and Treatment Effect of a Novel Device for Neck Pain in Active-duty Military Personnel With Forward Head Posture.

Neck pain is a common complaint among active duty military personnel, and can have tremendous impacts on quality of life and participation in duty-related activities. Treatments for spinal pain in military personnel are typically multimodal, relying upon physical therapy, pharmacological agents, spinal manipulation, and psychotherapy. However, there does not exist a wide body of evidence to support many of these treatments in active-duty military. The Cervigard neck collar was designed to treat posture-related neck pain with minimal effort and time required for treatment by the patient. However, this has yet to be tested experimentally. The objective of this study is to evaluate the treatment effect and safety of a novel device for the treatment of neck pain using self-reported pain and function measures, as well as objective radiological measures of cervical lordosis and head posture. Participants will be randomized to be fitted with and receive the Cervigard neck collar either immediately, or 6-weeks after being screened. Participants will complete neck pain and function questionnaires, and have cervical X-Rays collected at screening, treatment, 6 weeks, and 12 weeks (for the immediate group). Participants will be instructed to wear the collar every day for the duration of the trial. Self-reported neck pain and function measures will be collected, as well as cervical X-Rays, protocol adherence measures, and adverse events. The intervention is expected to reduce neck pain/discomfort, improve function, and improve cervical lordosis.

Description

Inclusion Criteria:

• DEERS Eligible
• Age 18 and 45 year old (inclusive)
• Neck pain duration ≥ 3 months without neurological signs and have been seen by a provider.
• Conventional treatments have not decreased neck pain

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in Numerical Pain Rating Scale score	Neck pain intensity will be assessed using the Numerical Rating Scale. Subjects will be asked to rate their average pain during the past week using an 11-point scale (i.e. 0-10) anchored at the ends by "no pain" and "worst pain ever experienced."	6 weeks

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in Neck Disability Index scores	The Neck Disability Index is a disease-specific measure of neck pain-related sequelae. It includes 10 sections designed to capture different aspects of everyday life and how neck pain potentially affects those areas. Examples include personal care, lifting, headaches, concentration, work, and sleep.	6 weeks
Change in lordotic angle of the cervical spine	The angle of the curve of the cervical spine will be measured using a custom computer program in blinded and random fashion.	6 weeks
Change in head position	The position of the cranium relative to the 7th cervical vertebra will be measured using a custom computer program in blinded and random fashion.	6 weeks
