Change From Baseline (Mean of Three Measurements at Screening, Prior to Treatment Visit 1 and Treatment Visit 1 Pretreatment) in the Average Visual Analog Scale (VAS) Pain Intensity Over the 5 Treatment Days
Pain intensity scored on a 10.0 cm VAS with the endpoints 0 = no pain; 10 = worst pain imaginable
Secondary Outcome Measures
Change From Baseline in Roland-Morris Disability Questionnaire (RMDQ) at Visit 5
The RMDQ is a 24 list of yes/no questions about the effects of back pain on the participants daily activities. Each positive answer is a point; maximum total score = 24.

Frequency, Severity, Nature and Duration of Adverse Events During the Whole Duration of the Study
Adverse events will be assessed using descriptive statistical methods and compared between treatment arms.
Vital Sign Parameters
Vital signs (blood pressure and pulse)will be assessed at each visit and changes from baseline compared between the treatment groups
Changes From Baseline in Skin Condition
Skin condition (erythema and hyperpigmentation as measured with the MX-18) and appearance (recorded with Polaroid photos) will be assessed once each at baseline and follow up, and before and after each treatment. The changes from baseline will be analysed using descriptive statistics and the two treatment arms compared.

5. Study Description
Brief Summary
The purpose of this study is to determine if the Pain Relief Patch, which shines light of a limited wavelength on the painful area of the back, relieves chronic musculoskeletal back pain. At the same time, this study will gather information on side effects associated with use of the Pain Relief Patch. The study will compare the Pain Relief Patch to a patch that is similar in appearance, but which shines a different, presumed nontherapeutic, wavelength of light.
Detailed Description
This study will test the Pain Relief Patch (PRP), a new device containing LEDs that is to be worn on the skin of the painful area, to see if it is effective in relieving chronic musculoskeletal back pain. It will also test the safety of the patch. The LEDs in the PRP emit a certain kind of light (peak wavelength 453 nm) that stimulates the production of nitric oxide (NO) in the skin. NO has been shown to induce a number of actions that should contribute to pain relief, including relaxation of smooth muscle cells, dilation of blood vessels, increased concentrations of oxygen in the cells and washout of metabolic byproducts and toxins caused by cell injury or death. Participants in one treatment group will be treated 5 times over 2 weeks for 30 minutes with PRP patches in the clinic. Participants in the control arm will be treated for the same length of time with a similar device that contains LEDs that emit another wavelength of light that does not induce production of NO. To prevent the influence of expectations on the results, neither the participants nor the medical staff directly responsible for their treatment will be told with which of the test patches the participants are treated. Other clinic staff will be responsible for all activities that could identify treatment arm, including putting the devices on and removing them, and examining the condition of the participants' skin before and after treatment. To get an accurate measure of how effective the devices are, participants will score their pain several times before the treatment period begins, as well as before and after each treatment. They will also complete several pain questionnaires during the study.

Blue light device, PRP patch, LED patch
Intervention Description
The Pain Relief Patch is a non CE-marked device that is worn on the painful area of the back, where it shines light (453 ± 7 nm, maximum 42 ± 6 mW/cm2 and average 20 ± 1 mW/cm²). It will be used 5 times over 14 days for 30 minutes each time.
Intervention Type
Device
Intervention Name(s)
Control PRP device
Intervention Description
The Control PRP device is also a non CE-marked device. It is similar in appearance to the active Pain Relief Patch, except that it shines light of a different wavelength(531 ± 7 nm, maximum 0.4 ± 0.1 mW/cm² and average 0.2 ± 0.05 mW/cm²) for just 5 seconds before it turns off. Participants in the control arm will be treated with the control PRP device 5 times over 14 days for 30 minutes each time.
