Abstract

A light therapy system provides for self-alignment or positioning with respect to a joint of a subject. The light therapy system can provide light therapy to a body part of a subject. The therapy system has a main body configured to be placed adjacent a target site and an activatable light emitting system is coupled to the main body. The light emitting system is capable of delivering a therapeutic amount of light energy to the target site when the main body is placed adjacent the target site.

8. The light therapy treatment system of claim 7 wherein the knee positioning structure is shaped and dimensioned to hold the knee at a knee flexion angle in a range of about 10 degrees to about 90 degrees.

9. The light therapy treatment system of claim 1, wherein the positioning structure comprises a lower elongate portion, an upper elongate portion, and an angled portion between the lower elongate portion and the upper elongate portion, the lower elongate portion is configured to receive at least a portion of a lower leg of the body part, the upper elongate portion is configured to receive at least a portion of a thigh of the body part, the angled portion is configured to receive at least a portion a knee joint of the body part and to define an angle of flexion of the knee.

10. The light therapy treatment system of claim 1 wherein the positioning structure is configured to guide the body part into physical contact with the light emitting system.

11. The light therapy treatment system of claim 1, further comprising:

a mounting system coupled to the positioning structure, the mounting system configured to hold the body part in engagement with the positioning structure, and the mounting system and the positioning structure form a brace that is sufficiently rigid to hold a joint of the body part in a predetermined range of positions.

12. The light therapy treatment system of claim 1 wherein the light therapy treatment system allows substantial joint movement during therapy.

13. The light therapy treatment system of claim 1 wherein the positioning structure has a preset configuration, the positioning structure in the preset configuration retains the body part in a treatment position that facilitates delivery of the light to the target site.

14. The light therapy treatment system of claim 1, further comprising:

a non-light penetrating energy delivery system positioned to selectively deliver a therapeutically synergistic amount of non-light energy to the target site.

15. The light therapy treatment system of claim 14 wherein the non-light energy comprises at least one of ultrasound energy, microwave energy, radiofrequency, mechanical pressure impulse energy, electromagnetic energy, and low level electrical currents.

16. The light therapy treatment system of claim 1 wherein the body part is a wrist, an elbow, a shoulder, a finger, a spine, a hip, an ankle, a foot, a hand, a jaw, or a toe.

17. The light therapy treatment system of claim 1 wherein the light emitting system is activated in response to signals from one or more pressure sensors positioned to engage the body part.

18. The light therapy treatment system of claim 1, further comprising:

a controller; and

at least one detector communicatively coupled to the controller, the at least one detector configured to measure a physiological indicator and to send a signal indicative of the physiological indicator, the controller configured to selectively command the light emitting system based at least in part on the signal from the at least one detector.
