EZ Stretch

The EZ Stretch is an in-home, mechanical, over-pressure therapy device recommended by orthopaedic surgeons and physical therapists for the purpose of helping patients regain Range of Motion (ROM) in their knee joints.

About the EZ Stretch

EZ Stretch

The EZ Stretch provides an exclusive, one-of-a-kind simultaneous bilateral action. It is the only product that offers both full-range extension and flexion in one device. Therefore, we can treat two problems for the cost of only one machine. The EZ Stretch uses an electric actuator that is completely controlled by the patient using a one-step hand control. The actuator moves a lever arm against the patient's ankle providing a variable load based on the patient's stiffness and tolerance to achieve either a flexion or an extension Stretch of the knee joint.

The device is used by a patient in their home in conjunction with physical therapy visits for an average of six weeks to regain ROM in their knee joint(s). The EZ Stretch is recommended as early intervention to prevent ROM complications or when traditional therapy and Stretching techniques have failed to produce normal ROM. The EZ Stretch can be used to avoid surgical intervention where, under anesthesia, the patient's knee is manually ranged by the surgeon in an effort to break-up scar tissue to regain normal motion.

Bilateral and Bidirectional

The EZ Stretch is the only product on the market that provides both flexion and extension in one device. It can be used to stretch both knee joints simultaneously if needed. Full Range Rehab offers in-home mechanical overpressure therapy for the patient suffering range of motion complications. The EZ Stretch provides an exclusive simultaneous bilateral action and produces a synergistic ROM overflow.

Highly Effective Elongation of Scar Tissue

Variable loads of torque applied to the knee joint (similar to those applied in clinic by physical therapists) are needed to permanently Stretch arthrofibrotic tissue. The EZ Stretch allows each patient to apply a magnitude of load that is specific to their own tolerance.

Unmatched Patient Compliance

Easy to Use - The patient sits on the device and begins their stretching routine. There are no straps, belts, difficult positions or adjustments.

Short Protocol - Stretching routines are performed in 15 minute sessions. Patient specific loads, similar to in-clinic physical therapy and short durations keep the patient focused.

Outstanding Results

Muscle guarding is eliminated because the patient is in complete control of the intensity of the load being applied. Patients see rapid improvements using the EZ Stretch and are encouraged to continue with their treatment protocol until they achieve a full recovery.

Glossary of Terms

The ACL is a ligament in the knee that crosses from the underside of the femur (the thigh bone) to the top of the tibia (the bigger bone in the lower leg). Injuries to the ACL can occur in a number of situations, including sports, and can be quite serious, requiring surgery. Typically, the surgery is done arthroscopically through small incisions in the skin to repair the ligaments, cartilage or bone within the knee joint area.


Arthrofibrosis is a condition that commonly occurs following knee trauma or surgery such as ACL reconstruction or Total Knee Replacement. Arthrofibrosis is due to inflammation and proliferation of scar tissue. When there is an overabundance of this dense, fibrous tissue, it can bind down the knee joint which prevents normal range of motion.


This procedure is a non-invasive procedure offered for acute and chronic conditions. Manipulation under anesthesia uses a combination of specific short lever manipulations, passive stretches and specific articular and postural kinesthetic maneuvers in order to break up fibrous adhesions and scar tissue around the knee joint and surrounding tissue.


Range of motion refers to the normal range of movement for a joint where it can move freely and painlessly. Range of motion in a joint is measured in two areas:

  • Flexion: how far it can be bent
  • Extension: how far it can be stretched out.

When scar tissue builds up around the knee joint, Range of Motion can be severly reduced causing pain & discomfort, gait problems, issues in the hip and back as well as the ability to a participate in activities of daily living.


As skin heals following an injury or surgery, scar tissue forms. Many factors can influence the amount of scarring each individual may have. This includes the age of the person; heredity; the location, size and depth of the wound; and individual skin characteristics including pigmentation (color). The procedure can be done one of three ways" using local anesthetic (patient is awake); sedated (sleeping) or with general anesthesia (a deep sleep and pain-free).


This surgical procedure is also commonly referred to as a Total Knee Replacement. This is a surgical procedure typically done under general anesthesia by an Orthopaedic Surgeon. The surgeon will remove the damaged cartilage and bone and then position new metal and plastic joint surfaces to restore the alignment and function of the knee.
