INTRODUCTION By enabling users to flex the orthotic leg during swing phase and safely lock it during stance phase, stance control orthosis (SCO) offers clear benefits compared to locked knee-ankle-foot-orthosis (KAFO)1. Since such orthoses do not offer dampened knee flexion in the weight-bearing condition, this represents a limitation in everyday activities such as ramp and stair descent. C-Brace, a microprocessor controlled stance and swing orthosis (SSCO), overcomes many of those problems. Maximum knee flexion angle in stance and swing phase during level walking are closer to physiological values with C-Brace compared to conventional KAFOs2. The patients are with C-Brace able to descend stairs and ramps reciprocally2. Furthermore, patients report of safer and easier ability to perform activities of daily living3. The main aim of next generation C-Brace is a reduction in size and an increase of adaptability to the patient’s anatomic structure. Due to technological changes, improvements especially for difficult ADLs (e.g. walking on uneven ground) are expected.
