Patent Pending Angled Step Position

-Allows for 10 degrees of supination in both directions

-Aids patients in maintaining proper hip and knee position with single leg squats

“We use PROSU with nearly every LE patient we see.  Being able to put the foot into supination really helps when initially training for proper knee position.”  

Ryan Tauzell, PT, Cert MDT

“First off, the adjustability of PROSU is great! Secondly, I love the small footprint of the design.  It is easy to move around the clinic when needed.  I have also used it frequently for my Home Health patients.”

Lindsey Krull, DPT

“Simple, strong, and very easy to use. Works amazing for ACL closed chain progressive single leg squats.”



Created by a Physical Therapist and Orthopedic Certified Specialist.  Its patent pending design provides progressive strengthening for the lower extremity.  It also allows for neuromuscular training for proper ankle, hip, and knee position with step down training.
