About

This is a prospective interventional trial with healthy volunteers at Methodist Dallas Medical Center. We anticipate data collection to be completed by December 2023. All study participants will be consented regardless of their role as healthy C-spine volunteer or provider volunteer (Appendix C). No compensation will be provided. Provider volunteers will be classified as:

• Attending
• Resident
• Physician assistant, nurse practitioner, or nurse
• EMS/Paramedic
• Other, as determined by job functions in pre-assessment

Full description

This is a prospective interventional trial with healthy volunteers at Methodist Dallas Medical Center. We anticipate data collection to be completed by December 2023. All study participants will be consented regardless of their role as healthy C-spine volunteer or provider volunteer (Appendix C). No compensation will be provided. Provider volunteers will be classified as:

• Attending
• Resident
• Physician assistant, nurse practitioner, or nurse
• EMS/Paramedic
• Other, as determined by job functions in pre-assessment Prior to placing C-collars, provider volunteers who will be placing C-collars will answer a questionnaire about their medical experience, their current position, their confidence in effective C-collar placement, and if they had formal C-collar training (Appendix D).

Healthy C-spine volunteers will lie supine. Cameras will be placed directly superior, anterior, and lateral to the volunteer's head. C-spine volunteers will be asked to actively move their head to the maximal flexion, extension, bilateral rotation, and bilateral side bending to assess baseline ROM.

Provider volunteers will individually place a C-collar on the C-spine volunteer's neck. They will have a range of sizes to choose from or adjustable units as applicable. The provider volunteer will be able to independently select and adjust a collar to best fit the C-spine volunteer.

The C-spine volunteer will then actively move their head to the maximal flexion, extension, bilateral rotation, and bilateral side bending with the C-collar on. ROM will be analyzed from video taken. This process will be repeated for each C-spine volunteer and each provider volunteer (Minimum 3 volunteers per 1 provider volunteer).

The angle of ROM in flexion, extension, rotation, and side bending without and with C-collar placement in each video will be measured using image analysis software. The decrease in ROM while wearing the C-collar for each encounter will be calculated. Scoring of C-collar placement will be done by an investigator while the provider volunteer is placing the C-collar. Providers will then receive additional information and resources specific to C-collar make/model placement and asked to complete a short survey (Appendix E) related to the content provided.

Provider volunteers will then have training on correct sizing and placing of C-collars and be reassessed in the same manor described above. Percent change will then be calculated for each volunteer provider.
