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

March 23, 2026 updated by: Nathan Hogaboom, PhD, Kessler Foundation

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.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
40

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 45 years (Adult)

Accepts Healthy Volunteers

No

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
  • Neck pain ≥ 4 on a 0-10 point numerical rating scale (0 = "no pain", 10 = "maximum pain")
  • Forward head posture, indicated by forward placement of the head relative to the shoulders.

Exclusion Criteria:

  • History of a tumor in the cervical spine and/or head/neck region within the past 6 months.
  • Infection involving the cervical spine and/or head/neck region within the past 6 months.
  • Generalized medical disorders that would weaken the vertebrae or other tissue structures within the cervical spine region.
  • Fracture that is acute and/or still healing
  • Spinal deformities (e.g. Fixed kyphosis, Ankylosing spondylosis)
  • Medical and/or psychological condition that would preclude safe participation

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in Numerical Pain Rating Scale score
Time Frame: 6 weeks
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

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in Neck Disability Index scores
Time Frame: 6 weeks
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
Time Frame: 6 weeks
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
Time Frame: 6 weeks
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
