The Paley Institute has a nifty "anti-gravity" treadmill (
AlterG) that lets you walk even if you can't weight bear. This is useful even for STRYDE patients, who need crutches in the first few weeks, so I thought I'd write about it.
Basically the machine is a treadmill with an air balloon on top. It lifts you by the groin (like a harness) using a sort of skirt which you wear and ends up being the cap the balloon. That takes off X pounds from your weight, so you can walk safely on the treadmill while respecting the weight limits of the nails.
Today I was still recovering from a very stiff left knee that I had been working on for the whole week. I couldn't fully extend the knee, and PT helped, but not completely. After 10 minutes of walking in the machine (which was painful on the left leg), I could fully extend the knee! This was way better than the NuStep machines, or the PTs.
Ask your PT to get you on the anti-gravity treadmill. Walking is the best PT.
