If the depth is only a few inches is that still too early?
As an “exercise” it’s too early. In my 8 weeks of PT, I was never asked to do sit to stands. Which means, all PTs vary in what they think we should do.
As I commented on another thread this morning, activites of daily living (ADLs) are all you need right now, and I call those “natural PT” In the course of your day, every time you sit down somewhere, and get up after a while, you have done a “sit to stand” “exercise.” The difference is, you did it at a natural pace, and spaced out, not X amount of reps all close together.
Some PTs honestly have no idea what all this surgery entails, they don’t understand the recovery, and for too many of them, their job seems to be focused on exercises and strengthening, which is fine for later, but not yet. Certainly not at only 8 days post op.
I think his goal is to get me a little more stable/less likely to fall by learning to engage my legs,
This is why you are using a walker. You will become more stable and therefore less likely to fall, as you heal. Healing takes time.
Regaining our ROM and strength is more about Time than repetitions of a list of exercises.
Time to recover.
Time for pain and swelling to settle.
Time to heal.
Our range of motion is right there all
along just waiting for that to happen so it can show itself.
In the general run of things, it doesn't need to be fought for, worked hard for or worried about. It will happen.
Normal activity is the key to success.
