Gait and Posture   37 457-459   Mar 2013
Ankle-foot orthoses (AFOs) can improve gait in patients with hemiplegia. However, it is anecdotally known that excessive plantarflexion resistance of an AFO could induce undesired knee flexion at early stance. The aim of this study was to systemat...

In this study, we proposed a method for estimating muscle length parameters on an individual basis from measured data based on a musculo-skeletal structure with a Hill-type muscle model. Passive joint moments of the ankle were measured for 4 healt...

Topics in Stroke Rehabilitation   19 338-344   Jan 2012
Background: Ankle-foot orthoses (AFOs) have been reported to have positive effects on the temporal-spatial parameters and kinematics and kinetics of gait in patients with stroke. The center of mass (COM) may be used to represent whole body movemen...

Gait and Posture   33 721-723   Apr 2011
Ankle-foot orthoses (AFOs) are commonly prescribed to improve gait. The stiffness of an AFO is central for successful prescription; however, the recommended level of stiffness is currently based on the experience of clinicians. Therefore, the aim ...

In an evidence-based rehabilitation context, establishment of a new ankle-foot orthosis (AFO) design method is required to make each user obtain a mechanically appropriate AFO which fits to the individual physical condition. In this article, we co...
