For hypertrophy, I don’t know exactly how effective it is. I DO know, for some knee pain, i did bodyweight box squats with it to try to teach stronger glute engagement, and I couldn’t sit right for a week.
I think the greatest part of it, is the aspect of it where it can find muscle tones that are off. So like….my shoulder hurts…ok well some imbalance is causing dysfunctional movement. So you place an anchor pad on the shoulder pain. Then you run another pad across the skin above and below the pain, looking for something wrong in the chain of muscles. When the machine finds a muscle that is somewhat contracted/weak due to muscle guarding, it shocks the shit out of you and it hurts.
My lower lat was the issue, causing shoulder issues. So you take the machine, and do more testing on the lat, get shocked a few more times, really nail down what is wrong with the lat.
Then you do basic PT movements (usually) with the neufit enhancing the contractions. Also good manual tissue work.
I’ll tell you this….when I was training for neufit, most of our clients were from the local school of dance. Lots of knee and ankle injuries.
We would have ballerina girls come in with high ankle sprains on crutches…2 weeks later they are walking normal, 2 weeks after that they are full go. And these were adults, not young kids that heal from eating Cheetos and a nap.
