Determine the most effective and efficient treatment protocols for treating neck pain with LLLT.
The purpose of this study is to identify what are the most effective low level laser therapy (LLLT) dosimetry parameters when treating pilots and navigators complaining of flight related neck pain.

| Group 1 -- using Pinnacle Series Laser Device | Procedure | Utilizing the Pinnacle Series Laser by Aspen Laser Systems, investigators will apply 635-780nm, 10 mW cw, ~ 5-105 J/cm2 at the following time and mW intervals. The beam will be applied at 12 application patterns equidistant and parallel to each other. Each application point will be treated for the timeframes referenced below:
|
| Measure | Description | Time Frame |
|---|---|---|
| Number of grounding days from flying due to neck pain -- Interval Variable | Number of grounding days from flying due to neck pain -- Interval Variable | Record during screening visit |
| Change in Neck Disability Index (NDI) | The NDI assessing functional capacity, has 10 parts, which evaluate pain intensity, personal care, lifting objects, reading, headache, concentration, work, driving, sleeping, and recreation. NDI scores, ranging from 0-50, may be doubled and also expressed as a percentage of function on a scale of 0-100%; thereby allowing the measure to be treated as an interval variable. It has also been categorized into 5 ordinal measurements, which are shown below with corresponding score and percentage measurements:
| visit 0 (screening visit), visit 1 (day 1), visit 10 (day 10) |
| Change in Defense and Veterans Pain Rating Scale (DVPRS) | The Defense and Veterans Pain Rating Scale is an assessment tool that utilizes a numerical rating scale, enhanced by functional word descriptors, color coding, and graphical facial expressions to evaluate a patient's self-reported pain levels. The DVPRS consists of an 11-point numerical rating scale with 0 indicating no pain and 10 indicating severe pain. It has been confirmed for reliability and validity in measuring both acute and chronic pain, and is currently the standard for pain measurement throughout DoD and VA health systems. The DVPRS has demonstrated linear scale qualities allowing parametric methods to be used. | visit 0 (screening visit), visit 1 (day 1), visit 10 (day 10) |
| Measure | Description | Time Frame |

| Change in Interleukin 2 Receptor (CD25) Soluble Biomarker Levels | Phlebotomists will draw 750 uL into 3 separate cryovials on two separate occasions. Interleukin 2 Receptor (CD25) Soluble Standard curve range: 4.25-17400 pg/mL | day 0 (pre-treatment), day 10 (post-treatment) |
| Change in Interleukin 12 biomarker Levels |
