The 904/905nm wavelength is the laser wavelength of the Handy Cure Laser and is one of the most researched in the scientific papers. Here are a few 904/905nm papers that cover a range of conditions.
LLLT administered with optimal doses of 904 nm and possibly 632 nm wavelengths directly to the lateral elbow tendon insertions, seem to offer short-term pain relief and less disability in Lateral Elbow Tendinopathy, both alone and in conjunction with an exercise regimen. This finding contradicts the conclusions of previous reviews which failed to assess treatment procedures, wavelengths and optimal doses.
Our study suggests that laser therapy is effective on pain, muscle spasm, morning stiffness, and total tender point number in fibromyalgia and suggests that this therapy method is a safe and effective way of treatment in the cases with fibromyalgia.
The tested laser photobiomodulation (GaAs, 904 nm) demonstrated positive results regarding the relief of painful symptoms in patients with TMD
