Is anyone using LLLT on non-brain areas? If so what are your protocols (duration, directly on skin or using ice bag also, etc.)? I'd imaging it'd be safer to use the LED longer on non-brain areas, but it heats up quickly. I have a nagging sprain around my ankle and am wondering if LLLT would help heal the area.
I don't use it that way regularly, but due to long term computer work I have issues with my neck and shoulder. My home brew diagnosis is 'geek neck' and some sort of impingement inside the rotator cuff, as my mobility of the right arm is restricted by pain when I lie flat on my back and try to move both arms backwards above the head. My left hand reaches the floor and while there is tension in the arm when doing this, there is no pain. The right arm though, can only reach so far back above the head before the pain from somewhere inside the shoulder makes it nigh impossible to move it further (and I suspect it would be a very bad idea to try to force it further than that).
Occasionally the entire neck/shoulder area gets very tight and painful, and restricts the movement of my neck. It was one of those times, after having this problem for several days, that I used the 48 LED at spots starting from the middle of the neck down all the way towards the shoulder, and then followed up with stimulating the left motor cortex and the upper part of the left prefrontal cortex. Following the LED therapy, I sat down to do breath meditation.
When I sat down, the pain was still very bad, and I also experienced discomfort and pain from my hips, knees and legs due to the meditation posture. However, a few minutes into the meditation, I was enveloped by a positively glowing sense of pleasant warmth, which made me feel as if I was sitting in a warm, cosy pain-free bubble. This persisted for approx. 13-15 minutes, then, after that, some body discomfort came back again, and at the end of the meditation I could still feel I was somewhat sore in the shoulder area, but nothing like before the LLLT. I then went to sleep. The next morning, the shoulder pain and restricted neck were gone. And they have not been back, at least to that extent ever since.
So I was very happy with that. I can't remember exactly how long I stimulated each spot, but I know for sure that it would not have been more than 2 minutes in any spot. I would suspect something like 30 sec - 1 min per each spot on the neck/shoulder, and 1-2 minutes over the left motor cortex and left prefrontal cortex.
