Knee orthosis braces segment can be divided according to availability of various braces that are used for supportive activities, such as knee orthosis, knee-ankle-foot orthosis
, ankle-foot orthosis, foot orthosis and others.
Although the patient was ambulatory and comfortable with the knee-ankle-foot orthosis
, he was advised arthrodesis of the ankle joint which he refused.

(KAFO) with myoelectric activation and inhibition," Journal of NeuroEngineering and Rehabilitation, vol.
Rahman and Ikeura developed a dynamic knee-ankle-foot orthosis
to offer variable-impedance dorsiflexion/plantarflexion training using a wrap-spring clutch .
The Active Ankle-Foot Orthosis (AAFO) , Knee-Ankle-Foot Orthosis
(KAFO), Berkley Lower Extremity Exoskeleton (BLEEX), and Hybrid Assistive Limb (HAL) belong to the leg orthoses and exoskeletons.

" Mechanism and Machine Theory, vol.
A portion of the knee-ankle-foot orthosis
(KAFO) user population would still require an orthosis that rigidly controls knee flexion during every step for confident and safe locomotion.
The patient was placed in a knee-ankle-foot orthosis
(KAFO), which provided support to her unstable knee, to be worn all day and removed at night.
"The metal knee-ankle-foot orthosis
fabrication in the lower limb orthotics course seems to be the most technically challenging Learning Activity Packet (LAP)."
Other devices designed for ambulation with lower-extremity dysfunction are: a mechanical device, double upright KAFO (knee-ankle-foot orthosis
), the hybrid devices utilizing bracing with functional electrical stimulation (FES), or the high-tech system utilizing only FES.

The design of the SCKM consists of a miniature hydraulic system attached across the knee joint to the thigh and leg up rights of the knee-ankle-foot orthosis
(KAFO) via revolute joints in a four-bar linkage arrangement for linear-to-rotary transmission (Figure 1).
