Went 2X the first week 10 days after surgery, found the second one in that same week a weak lesson, so I personally cut mine down to once a week. I took things in my own hand for I am very active and know my body. I was even directing my PT person on my needs, and asked what was best, then for that week I improved myself...so take it as how comfortable are you in knowing what is best for you body. Do you know what you feel is week? Do you strive to get it back and do you need someone to tell you when to move yourself to improve what is weak? I am the guy who won't go others to tell me how to fix things...but I did go to find my ROM and some tips on how to excersize myself, but I did most all of it on my own, and once a week let the PT do their thing, and I always wanted to show off and prove that I was improving at my pace. (I did at home PT every day for around 8 weeks with only a day or 2 of off days and just rested, but my PT was focused and I knew what I wanted to achive, so I think I was ahead of the scale)
I stopped PT because I felt too good and my life was asking too much from me and in my life,(plus, who has time to schedule that when life is calling) its like PT anyways, and at my job I did PT when time let permits, so to me, I feel 90% right now, 80% at 10 weeks, and the reason for the 10% growth-I got back to life.. I am only 14 weeks out today.
I might not be the average, but for me I grew faster then them(the PT people, I think I was one of the first in that clinic with a resurface)
