Method for regeneration and functional recovery after spinal cord injury using phototherapy
View Patent ↗A method of treating spinal cord injury (SCI) includes transcutaneously irradiating at least a portion of a spinal environment of the patient with light having a power density of at least about 0.01 mW/cm 2 at the portion of the spinal environment.
1. A method of treating a patient with a spinal cord injury, the method comprising:
irradiating a first portion of a skin surface of the patient with light, the first portion of the skin surface at least partially overlying a spinal environment of the patient, the spinal environment comprising the meninges, the cerebrospinal fluid, and the spinal cord, wherein the light is directed in a direction that generally intersects at least a portion of the spinal environment; and
irradiating a second portion of the skin surface of the patient with light, the second portion of the skin surface at least partially overlying at least a portion of the motor cortex of the patient's brain.
2. The method of claim 1 , wherein the light irradiating the first portion of the skin surface has a power density of at least about 0.1 mW/cm 2 at the first portion of the skin surface.
3. The method of claim 1 , wherein irradiating the first portion of the skin surface is performed for a first specified treatment period and irradiating the second portion of the skin surface is performed for a second specified treatment period.
4. The method of claim 3 , wherein the first specified treatment period is two weeks, wherein the first portion of the skin surface either is irradiated continuously during the first specified treatment period or is irradiated with alternating periods of irradiation and rest during the first specified treatment period.
5. The method of claim 3 , wherein the second specified treatment period is in a range between about 11 days and about 15 days after the initiation of the first specified treatment period, wherein the second portion of the skin surface either is irradiated continuously during the second specified treatment period or is irradiated with alternating periods of irradiation and rest during the second specified treatment period.
6. The method of claim 1 , wherein the light irradiating the first portion of the skin surface has a wavelength in a range between about 580 nanometers and about 850 nanometers.
7. The method of claim 1 , wherein the light irradiating the first portion of the skin surface has a wavelength in a range between about 720 nanometers and about 820 nanometers.
8. The method of claim 1 , wherein the light irradiating the first portion of the skin surface has a wavelength of about 810 nanometers.
9. The method of claim 1 , wherein the light irradiating the second portion of the skin surface has a wavelength in a range between about 580 nanometers and about 850 nanometers.
