INTENDED USE
The intended use of the Matrix MD-S711 Medical Leg Extension / Leg Curl is 
to create a predetermined, dened physical activity level for the patient. The 
physical activity level is generated by the user pushing against a movable leg 
bar. The user can either use the back of the ankle to press the leg bar in the 
downward direction to perform a Leg Curl exercise, or the user use the front of 
the shin to press the leg bar in the upward direction to perform a Leg Extension 
exercise. This physical activity level can be done in the controlled environment 
of a doctor’s oce or a clinician’s lab. The stress intensity of the physical activity 
level can be adjusted by adjusting the amount of resistance applied to the leg bar, 
or by the perceived effort as described by the user to the doctor or clinician.
Metabolic System: The medical leg extension / leg curl can be 
used to inuence the metabolic system to increase fat-burning, 
thereby reducing the size of adipose tissue deposits.
Physical Performance Tests: The dened stress intensity of the 
physical activity level can be used to perform physical performance 
tests on the strength of the user’s leg muscles. 
Recovery: Under a doctor’s care, the medical leg extension / leg 
curl can be used to improve muscle strength after surgery or injury. 
The handrails and seat of the medical leg extension / leg curl can 
be used for additional safety and stabilization of the patient.
Orthopedic Rehabilitation: Under a doctor’s care, the medical leg extension 
/ leg curl can be used for orthopedic rehabilitation (e.g. supporting 
dened/reduced weight to strengthen the legs of a user).
