Comparison of Cervical Motion Restriction and Interface Pressure Between Two Cervical Collars

August 20, 2021 updated by: More Foundation
Cervical orthoses are used to restrict motion for the purpose of preventing spinal instability following trauma or pre- and post-surgery or to protect from pain. Modern cervical orthoses are able to effectively restrict motion of the head however load is concentrated on areas of occipital tissue and may, with long term wear, lead to tissue breakdown in the form of pressure ulcers. Previous research has shown that the Miami J collar (Össur Americas Foothill Ranch, CA) effectively reduced cervical movement while providing superior pressure relief. As new cervical orthoses are developed and become commercially available it is useful to examine their performance in comparison to existing well-tested devices. DJO Global (Vista, CA) have recently developed a cervical collar. The purpose of this study is to compare the ability of this newly developed collar to restrict cervical range of motion while at the same time limit the tissue interface pressure exerted by the collar on patients when they are in an upright seated or supine position Data will be collected in a fully equipped 3D motion analysis laboratory. Cervical range of motion will be tracked and analyzed. Interface pressures between the head and collar will be measured using custom pressure mats.

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.

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.

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
Cervical range of motion
Time Frame: At enrollment
The subjects will be seated in a backed chair and monitored to ensure their spine remains in contact with the backrest throughout the CROM assessment. Each subject will be instructed to perform a sequence of of neck flexion-extension, lateral flexion, and rotation movements. Each movement will be repeated six times until the motion is stopped by muscle tightness, discomfort or a substitution movement occurs, without a collar, and with each study collar chosen chosen in random order. Angular range of motion in degrees will be recorded in each plane. Flexion-extension - angle between maximum flexion and maximum extension. Lateral flexion - angle between maximum right lateral flexion and maximum left lateral flexion. Rotation - angle between maximum right rotation and maximum left rotation.
At enrollment
Tissue interface pressure
Time Frame: At enrollment
With the subject seated, 3, 75 x 120mm pressure sensor pads, each pad each consisting of 40 individual sensors; will be placed over the anterior mandibles and occiput. The subject will be fit with an appropriately sized collar. The order of collar wear will be the same as for the CROM measurements. Pressure measurements and distribution of pressure will be recorded for a period of 30 seconds. The subject will then be placed in a supine position on a standard examination table without a pillow and pressure measurements and distribution of pressure will be collected for a period of 30 seconds while the subject maintains his/her head in a relaxed position.
