Wonderful thing..I'm sure others here have experienced PT and know how well it works.. This is my 4th time (for other things) and it always does the job..This time is muscle degeneration..My legs have become so weak that they feel like they're gonna collapse at any time..My balance is just about gone.. Now after 5 visits they have me walking much better..Still need to work the small muscles more though for better balance.. They keep telling me it's the "use it or lose it" syndrome ..I guess.. I have great faith in this and know it will solve most of the problem.. How about you??
