L4D Lower Extremities CPM

The L4D and L4KD’s digital controllers features include Reverse on Load, end of range Pause time, Warm-Up mode, a Treatment Timer, and the ability to track user hours and cycles.

The controller’s unique design allows settings to be saved to a Patient Memory Key to eliminate repetitive data entry, and a lock ensures that only you make program changes.

Both units quietly provide simultaneous hip and knee motion, and the L4D adds adjustable ankle motion for a total limb CPM.

Healing In Motion

Research continues to demonstrate that moving a limb or joint aids rehabilitation and leads to better outcomes. By combining active physical therapy along with a Continuous Passive Motion (CPM) device, it is possible to significantly increase joint range of motion.
