A 58-year old male (Denny) presented to my office one month ago with post low-back disc surgery and right-sided foot drop. He has had little to no improvement since his disc surgery that was performed in September 2012. Denny was having a lot of difficulty walking and going up stairs due to his right toe “catching” on carpet and steps. I suggested we try a series of K-laser treatments to try and wake up the nerve in the front of his shin and also at the low-back surgical site. After two visits Denny appeared to make only a small degree of improvement. While I expected a slow process, I wanted some tangible objective evidence to see how bad his nerve was damaged and what the chances of success might be. We did a surface EMG on his shin muscle and could measure his voluntary muscle contraction capability. It was in this case about 60 milliamps. Typically 100 milliamps is needed to engage the tibialis anterior to contract and lift the foot. So armed with this info, we made a plan to continue treatments and re-measure every three sessions to look for electrical response success, which would probably precede and then predict more successes. The next measurement revealed a capacity of 76 milliamps and Denny was feeling some more control of his shin muscle. I believe at this pace he will reach near 100 milliamps within about five more visits, and then likely we will see a more normal contraction of this shin muscle and subsequent improved ability to gain further strength and function. In this case the combination of the K-laser and the S-EMG helped predict and encourage our process as we help Denny on his path to improvement.
