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).

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).
Optimization and application of a wrap-spring clutch to a dynamic knee-ankle-foot orthosis.
To test for the effect of assistive mobility devices on sensor-fused orientation output, we used the following devices: exoskeletal transtibial prosthesis, endoskeletal transtibial prosthesis, knee-ankle-foot orthosis (KAFO) with aluminum uprights, KAFO with stainless steel uprights, ankle-foot orthosis, Challenger Low Wide walker (Evolution Technologies; Port Coquitlam, Canada), standard walker, Tango wheelchair (OrthoFab; Quebec City, Canada), and GTi wheelchair (Quickie; Phoenix, Arizona).
Abbreviations: 3-D = three-dimensional, KAFO = knee-ankle-foot orthosis, RMS = root mean square.
The cylinder was mounted to the thigh upright of the knee-ankle-foot orthosis
via a clevis (Figure 2), and the pinion was fixed rigidly to the corset.
For people with isolated quadriceps weakness or paralysis, a standard knee-ankle-foot orthosis
(KAFO) is typically prescribed to support the limb during locomotion.
