Efficacy of a Home-Use Photobiomodulation Device for the Treatment of Patients With Knee Osteoarthritis

Study Overview
=================
Brief Summary
-----------------
Osteoarthritis is a degenerative disease affecting joint cartilage and its surrounding tissue. It is the leading cause of disability in the elderly. Photobiomodulation (PBM), has been used widely for alleviation of pain, reduction of inflammation, and acceleration of wound healing, and particularly to treat knee osteoarthritis (KOA). The purpose of the current study is to determine if B-Cure laser treatments, applied at home, by the patient or personal caregiver in a real-life situation, can reduce pain and improve functionality in patients with KOA.

Detailed Description
-----------------
Eligible patients with knee osteoarthritis will receive a B-Cure laser device for self-application at home in addition to standard care. Patients will be invited to the clinic for 3 visits: baseline, 1, and 2 months. Evaluations at the visits will include physical examination, knee range of motion, time up&go test, and patient reported outcomes including subjective pain level by visual analogue scale (VAS), functional and quality of life questionnaires. The study hypothesis is that B-Cure laser treatments, applied, at home, by the patient, can ameliorate KOA related inflammation thereby reducing pain and improving functionality in these patients.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Standard treatment + Active B-Cure laser<br>Subjects from Standard treatment + Active B-Cure laser will receive standard care and in addition will self-treat at home with the B-Cure device. | Device: Standard treatment + Active B-Cure laser<br>* The B-Cure laser pro is a portal, non-invasive, photobiomodulation device, that emits light in the near infrared (808nm) over an area of 1X4.5 cm2 with power output of 250mW, and energy dose of 5J/minute.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| level of pain | Change from baseline in pain score by VAS | one month | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change from baseline in WOMAC score [ time point - 1 month] | The WOMAC is a disease-specific tool used for people with hip or knee OA to measure physical function, pain, and stiffness. It widely used in clinical studies as primary or secondary outcome. | one month |
