Support weight

Control involuntary movement

Prevent malformation

Adaptation requirements for lower limb orthosis:

The hip, knee, and ankle axis of the orthosis must correspond to the axial position of the physiological joint, and the hinge axis of the ankle should pass through the inferior or lateral iliac crest. The knee hinge axis corresponds to the most prominent point of the femoral condyle. The hip hinge axis is located on the greater trochanter. 45mm, and slightly forward. The hip and ankle joints are located in the same frontal plane, and the axes of the hips, knees, and ankles should be parallel to each other. The angle of movement of each hinge should meet the requirements specified in the treatment.

When carrying weight, the gap between the struts and hinges and the skin should not exceed 5-10mm.

Each hinge has no noise, no resistance work, and is rotated and implanted, and the opening and closing is flexible, and there is no looseness after locking.
