The biomechanical principles of lower limb Orthotics

What is the biomechanical principles of lower limb orthotics? 

All lower limb orthotics is required to produce a therapeutic effect on the body by applying a force. Thus orthotics designers should understand their function in generating the action and playing adaptation. The method is generally used to describe according to  the magnitude and direction of the force,three point force.

All the movements are rotating, moving, or a combination of both. The change of rotation angle does not change the height of the moving direction.The force affecting the effectiveness of the joint decides on the force point ( Or between the rotary axis)and the magnitude of force.Thus, lower limb orthotics is going through leverage to achieve the best effects. Function of lower limb othosis  is generated through the leverage :  stability and support, the generation of power, correction deformities and limb protection.

Like the Orthopedic Walker Boot has emergency immobilization for forefoot, ankle, tibia end injuries.

Post-op Knee Brace can have conservation treatment and external prevention for knee and its soft issue injuries

Also recently I read a very useful blog of PRIMARY INDICATION OF LOWER LIMB ORTHOTICS,you guys want to know about the lower limb orthotics,should check it.
