The spasms, are you on Calcium w/d3 or Magnesium? I had wasting of quads,gluteus maximus, Illiopsoaz(the muscle that lifts the knee). They did not respond to Physical Therapy, it was as if the wiring to the muscles was not connected anymore. I still exercize but not in an attempt to weight train. Early on, I set benchmarks for frogress. I have went from using a walker to free walking,woo-hoo. I also had (at the start) to lift my leg up into a pickup truck to get in. That is still the same and I blame the Illiopsoaz as not responding or rewiring or releasing or whatever. I agree that your symptoms are not due to weakness but nerves. But isn't it true if the nerves don't fire the muscle weakness is next. My thighs used to be huge as I made a living climbing stairs all day. (280 lbs) Now they are not as big and I can walk about 100 yds before hunting a place to sit down. My experience with a rehab trained massage therapist was nore valuable to me that PT. I hear conflicting stories so I guess it's whatever works for you. Good Luck, Ken in Texas.
