What Direct Current E-Stim Shows About the Quad After an ACL Tear
On the Starting Block podcast, Zach explains why an ACL tear shuts down the quad, and what he sees when direct current e-stim goes on both legs.
What e-stim is, how TENS, EMS, and direct current e-stim differ, and how to use stimulation to build muscle and move better.

On the Starting Block podcast, Zach explains why an ACL tear shuts down the quad, and what he sees when direct current e-stim goes on both legs.

A TENS unit is built to ease pain, and an EMS unit is built to make a muscle contract. Here's how to tell which one you own, what the research says about e-stim after ACL surgery, and where direct current e-stim fits.

Your muscles may be capable of more than your body is currently allowing them to do. That might sound strange. We tend to think of performance as a simple equation: if you want to get stronger, build more muscle. If you want to move better, practice the movement. If you want to perform at a higher level, train harder. But your muscles don't operate independently.
