T-REX Stands for Total Range Exerciser

Our T-REX patented technology provides the only at-home rehabilitative system with a powered dual & tri-actuator polycentric hinge design. Total Range Exercisers (T-REX) are considered “High Intensity Stretching” devices designed to break down scar-tissue that limits a patients Range of Motion (e.g. arthrofibrosis of knee, adhesive capsulitus of shoulder). They emulate the force and motions a therapist applies during physical therapy sessions.

Studies document that using a high intensity stretching device produces significantly better patient outcomes then a low intensity stretching device, such as dynamic or static-progressive braces. In one particular knee study, 91% of patients using high intensity stretching devices were able to achieve a functional range of motion greater than 110 degrees compared to the low intensity stretch group, who saw only 22% of patients able to achieve a functional range of motion greater than 110 degrees.

91% of patients using high intensity stretching devices were able to achieve a functional range of motion greater than 110 degrees versus 22% using low intensity stretching.

Better Patient Outcomes

Studies show that in order to successfully break down and permanently elongate scar-tissue, a process called “plastic deformation” needs to take place. (2) In order to achieve “plastic deformation” of scar-tissue it is imperative to emulate the “high intensity stretching” forces applied by physical therapists and to do so in a series of repetitive sessions every day.

T-REX Is Designed to Combat Excessive Scar-Tissue

T-REX functions much differently than a Continuous Passive Motion (CPM) device. CPM machines lack the force and intensity required to address contracture problems related to excessive arthrofibrosis of the knee joint (i.e. stiff knee) or adhesive capsulitis (i.e. frozen shoulder).

This is why a device like T-REX is so important. It is designed to meet the needs of a specific group of patients that are struggling to regain their Range of Motion. T-REX fills an important void in patient care. Currently a large chasm exits when it comes to providing “high intensity stretching” devices for adjunct home therapeutic care designed specifically for the rehabilitative needs of a patient dealing with contracture concerns. T-REX was created to be part of the solution.
