LM 120 with HyperX

Linear Motion 120, LLC is a durable medical equipment company that has designed, engineered, fabricated and manufactured the LM 120 with HyperX to be used before and following total knee replacement surgery and to rehabilitate sprained or torn limb ligaments.

HyperX Mode

HyperX Mode uses two thigh straps, two cams and two forward and reversing motors to depress the leg up to 0.75 inch/19.5 mm.

Therapy Mode

Therapy Mode allows the client to reach flexion and extension goals programmed into the computer by the physical therapist, based on the client’s femur and tibia measurements.

Exercise Mode

Exercise Mode is to sustain and maintain the ROM achieved in the Therapy Mode. This entails continuous linear movement from hip-to-knee-to-ankle for up to 10 minutes, repeated in four, 15-20 minute daily sessions until the ROM of the non-surgical leg is reached.

Linear Motion 120 with HyperX

The LM 120 with HyperX is a FDA Class I Medical Device used as a physical rehabilitation apparatus following total knee replacement (TKR) surgery and to rehabilitate sprained or torn ligaments. The LM 120 with HyperX is intended to increase the degree of flexion (bending) and extension (straightening) of the surgically affected limb. The apparatus consists of four main components: 1) the Resting Platform; 2) a Connecting Mechanism; 3) the Actuator Enclosure Assembly; and 4) the Tablet.

Support Platform

A sturdy base layer of plexiglass covered in non-slip neoprene supports the unit components when placed on a table or bed. The long arm of the L-shaped platform is flipped over to correspond with the right or left positioning of the Actuator Enclosure Assembly and the effected leg. The white outline is positioned close to the wall or head of the bed and designates the positioning of the Resting Platform. The aluminum rectangle of the Actuator Enclosure Assembly rests on the blue line.

Resting Platform

The function of the Resting Platform is to provide a comfortable surface where the client’s hips are stabilized, preventing the hip from rising up, sliding forward or moving side-to-side during therapy of the knee. A one-inch pummel (bolster) at the front of the cushion further restricts client forward movement. The Resting Platform is a two-piece, hinged aluminum frame. The seat is upholstered in high-density foam and medical-grade vinyl, which is impervious to disinfecting solutions.
