Design Changes in Ankle-Foot Orthosis Intended to Alter Stiffness Also Alter Orthosis Kinematics
Robert Singerman, PhD
David J. Hoy, BS, CPO
Joseph M. Mansour, PhD
The authors attempt to determine whether kinematics of an ankle-foot orthosis (AFO) are dependent on design changes made to alter stiffness.

Kinetic Patterns During Stair Ascent in Patients with Transtibial Amputations Using Three Different Prostheses
H. John Yack, PhD, PT
David H. Nielsen, PhD, PT
Donald G. Shurr, MA, PT, CPO
This study used three different prostheses to determine the ways in which each affected the kinetic strategy used by patients with unilateral transtibial amputations during stair ascent.

Case Study: Improving Knee Extension with Floor-Reaction Ankle-Foot Orthoses in a Patient with Myelomeningocele and 20° Knee Flexion Contractures
Donald Freeman, CP
Michael Orendurff, MS
Michael Moor, CPO
A patient with an L-5 level myelomeningocele underwent gait analysis testing while barefoot and while wearing floor-reaction ankle-foot orthoses (FRAFOs) set in 10° dorsiflexion to demonstrate how FRAFOs can provide a significant increase in knee ext...

Transition to an Articulating Knee Prosthesis in Pediatric Amputees
Bryan Wilk, BS
Lori Karol, MD
Suzanne Halliday, MS
Don Cummings, CP
Nasreen Haideri, ME
John Stephenson, CP
Children were monitored at three different stages to determine if gait deviations resulting from the lack of knee flexion in solid knee prostheses are reduced when a young amputee is fit with an articulating prosthesis at an earlier age than the prev...
