Zusammenfassung: This paper presents an evaluation of the loading capacity of the Ottawalk-Speed Stance-Control Knee Orthosis (SCKO), which employs an angular velocity control approach to switch between free motion and flexion resistance modes.

Zusammenfassung: An intelligently controlled compact MRF (Magneto-Rheological Fluid) brake was developed and installed in ankle-foot orthosis. The Effectiveness of the device was proved based on the gait analysis of hemiplegia patients.

Zusammenfassung: The PatellaTrack orthosis (Otto Bock HealthCare GmbH)was evaluated in an in-vitro study. Bone pins screwed into Tibia and Patella of six cadaver legs indicate the biomechanical efficacy of the brace in regard to re-positioning and medial transition of the Patella during knee extension and flexion.

Zusammenfassung: The puopose of this study was to determine gait differences in three subjects ambulating with a conventional RGO with a locked knee and a RGO with a stance control knee. The subjects ambulated in doubled walking speed and stride length with stance control orthosis because of knee flexion.

Zusammenfassung: Ensuring functionality, durability and usability of technical aids is crucial for both manufacturers and health insurance providers. This paper describes the properties and usage of novel testing devices for functional, fatigue strength and microclimatic testing of knee braces.

Zusammenfassung: This abstract presents a method which delivers an insight into the “patient - orthopaedic aid” system using three dimensional image acquisition methods in an open low-field MRI scanner under physical loading conditions controlled by self-built MRI compatible measurement techniques.
