There was one thing that made the difference for both of my knees. I got to point where little progress was being made. That is when the PT decided to use the electrodes. I think you really need to have one who knows how to use these right. My PT put them in the right places, knowing the muscles, etc, and GENTLY would turn up the charge till it was working right. She had another way she would cause it to flucuate higher to lower and tell me when to do the specific exercise for that part of the knee. It really did help greatly. It did not hurt, it did feel different or a little funny. I can see if the PT was not gentle but aggressive with this that it would not be pleasant. One time one of the lesser assistants did it on me, and she was lousy, I called for the PT to come over. Then she redid the whole thing. It is said to stimulate the nerves and muscles. I think the nerves are growing at 3 MILLIMETERS (wow so small) in about 6 weeks. I can say at 6 months on the first knee it became amazingly different and much progress was made. I can also say with the first knee I was making some type of progress in months 6 to 12. I keep telling myself this with the right knee done on June 2nd, and encourage myself to have patience. I still feel better than before the surgery. I know when I am TOO tired, like tonight....:th_heehee: that it is easy to get discouraged, or to think "no more progress." But remember things will get better in time. There is hope for this. Hang in there. What else can one do? But then act like there is a choice and it will make a difference. Why? Because there is a choice, do hang in there!
