Take control of your rehab.

A big part of what makes recovery from knee replacement or ACL surgery difficult is the loss of quadriceps strength. In fact, most patients lose over 60% of quad strength after knee surgery, which can prevent you from getting back to a normal, active life.

Understanding Quadriceps Weakness

Quadriceps atrophy – or the weakening of your thigh muscles – is a common but overlooked result of knee surgery. As your muscle atrophies due to the inability to use your knee before and after surgery, the communication between your nerves and muscles becomes hindered. This limits your ability to recruit your quadriceps and weakens the signal between your nerves and muscles.

Our neuromuscular electrical stimulation (NMES) solutions are designed to help speed up the recovery process, with an emphasis on comfort and convenience-so you can work on your rehab outside of the doctor’s office from home, work, or just about anywhere else.
