Mechanical assisted active orthosis using a robotic application
First Claim
1. A knee orthosis apparatus for providing varying levels of support to a patient during a stance phase and a swing phase of a gait cycle, the apparatus comprising:
- an upper auxiliary support adapted to be positioned at a lateral thigh region of the patient;
a lower auxiliary support adapted to be positioned at a lateral calf region of the patient;
an actuator adapted to be positioned between the upper and lower auxiliary supports;
a sensor configured to detect a plurality of leg movements during the gait cycle and to output a plurality of detection signals corresponding to the detected leg movements; and
a processor communicatively coupled to the sensor, wherein the processor is configured to;
determine whether the knee is in the stance phase or the swing phase of the gait cycle based on the plurality of detection signals,control the actuator to apply pressure on the lower auxiliary support in a lateral direction relative to the upper auxiliary support when the knee is in the stance phase, andcontrol the actuator to release pressure on the lower auxiliary support when the knee is in the swing phase.

Abstract
A knee orthosis provides varying levels of support to a patient during a stance phase and a swing phase of a gait cycle. The orthosis comprises an upper auxiliary support, a lower auxiliary support, an actuator, a sensor configured to detect a plurality of leg movements during the gait cycle and to output a plurality of detection signals corresponding to the detected leg movements, and a processor configured to determine whether the knee is in the stance phase or the swing phase of the gait cycle, to control the actuator to apply pressure on the lower auxiliary support when the knee is in the stance phase, and to release pressure when the knee is in the swing phase.
