A patient wearing a KAFO complains of anterior distal thigh pressure while sitting? What could be the cause?

What is the necessary clearance on the lateral knee joint while building a KAFO with a drop lock?
6mm
Name two muscles which extend the hip
Gluteus maximus, hamstrings, posterior head of the adductor magnus
Name two reasons why an AFO might be denied payment
- incorrect use of HCPCS code
- patient must be ambulatory

A patient is getting anterior proximal pressure on the calf in both dorsiflexion and plantarflexion - where is the orthotic ankle joint relative to the anatomical ankle joint?
Orthotic ankle joint is posterior to the anatomical ankle joint.
Tinkerbell fell during the Fantasmic light show and has a right diaphyseal fracture of her tibia. What might be an appropriate orthotic intervention and name one property of that intervention.

Minnie had a Left CVA and has Right drop foot with some equinous and clonus. What might be an appropriate ankle joint and why? Would you need a plantarflexion stop or not and why?
Any joint without dorsi assist - add a plantarflexion stop.
Which bone of the foot is often prominent and most troublesome especially in pes planus feet?
Navicular
Why do transmetatarsal amputees often develop plantarflexion contractures?
Name an instance when you would use a heel lift to increase dorsiflexion (as opposed to increasing the angle of dorsiflexion at the ankle or altering the plantarflexion stop)
- When you are using a solid AFO
- Knee flexion contracure
- Plantarflexion contracture
