Abstract
A method for the treatment of spinal cord transection using low level laser therapy in combination with allogenic implants. In one embodiment, embyronal nerve cells are cultured in vitro and transplanted to a site of spinal cord transection. The site is surgically closed and LLLT applied to a treatment point on the skin adjacent the transection site. To apply LLLT, a therapist applies pressure adequate to blanch the skin at the treatment point, and applies laser energy having a wavelength of about 630 nm to about 904 nm, with laser apparatus having a mean power output of about 100 mW to about 500 mW, at a dosage of about 1 joule/point, up to and including about 30 joules/point. Treatment times, total dosage, and number of treatment points are determined by the therapist or clinician trained in LLLT.
