Evaluating Light Therapy for Treatment of Overuse Anterior Knee Pain (LLL&KP02)
Evaluation of the Efficacy of Light Therapy for the Treatment of Anterior Knee Pain: A Prospective, Randomized, Double-Blind, Sham-Controlled Clinical Trial

Detailed Description
During basic training, 15% of military recruits develop knee pain on the background of overuse, which hinders their chance to complete training, and leads to high dropout rate with the accompanying cost to the system. When KP is due to overuse, the time to complete resolution is typically 2-3 months, but symptoms may last for years. Current therapeutic options have had variable levels of success. Finding an alternative non-drug, non-invasive therapeutic modality that is easily incorporated in a field setting and may shorten the resolution of pain may lead to earlier return to duty thereby reducing the associated cost to the system and to the individual soldier.
Low-level laser irradiation (LLLI) is non-ionizing and non-thermal, and is within the visible to near-infrared range of the electromagnetic spectrum. LLLI has been used widely for alleviation of pain, reduction of inflammation, and acceleration of wound healing. Pre-clinical and clinical studies have shown that LLLI reduces pain in chronic inflammatory related knee pathology. However, little is known about the effect of LLLI on acute knee pathology that account for 25-40% of all knee problems in athletes.
The current study is a prospective, randomized, controlled double blind clinical study designed to evaluate light therapy, as an adjunct to conservative physiotherapy for treatment of acute overuse KP in combat soldiers.
The treatment protocol includes conservative physiotherapy and in addition, biweekly sessions of light therapy or sham irradiation for 4 weeks. Two follow up visits will take place at 1 week and 3 months after the last treatment.
Study evaluations will include physical examination, physical activity tests, subjective pain level by visual analogue scale, improvement and satisfaction scores, and functional questionnaires.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Light Therapy
Subjects from this group will receive 8 biweekly physiotherapy treatment and in addition Light Therapy treatment with the THOR laser LX2 system.
|
Treatment session will take up to 25 minutes and will include stimulation of local lymph nodes and soft tissue, de-activation of trigger points, and eliciting analgesia.
|
Sham Comparator: Sham Therapy
Subjects from this group will receive 8 biweekly physiotherapy treatment and in addition Sham Therapy.
|
The therapeutic light will be turned off but the system will produce similar noises and mild heat.
