Now we get to use curls to fix elbows. How ’bout that?
This month, Stephen LaFlamme and I ran through a bunch of physical therapy, orthopedic testing, and advanced functional anatomy. If you’re not good at visualizing anatomy, you may find this one frustrating. Take your time, pause and research when necessary.
A note on the brachioradialis retracting the forearm: this occurs during loaded elbow movements to prevent olecranon compression at the posterior elbow. You’ll see that brachioradialis (a flexor), triceps (extensor), and anconeus (extensor) are all innervated by the radial nerve. The other flexors are innervated by the musculocutaneous nerve. Pretty cool, eh?
