Orion3 is suitable for K2 to K4 walkers who would benefit from stability on different terrains, slopes and steps and for those wishing to walk naturally and efficiently at either single or varying speeds.
The safety and stability of Orion3 encourages users to evenly distribute their weight, offloading their sound side and lower back to reduce aches and pains commonly reported by amputees.
Enhanced Stability Performance (ESP) increases the user’s confidence and independence, reducing the risk of stumbles or falls and ensuring more balanced limb loading for greater long term health and protection.
ESP adapts hydraulic resistance in real time, providing optimal stance support whether walking in a crowded environment, on uneven terrain, slopes, steps and now also when standing. With situational awareness, Orion3 continuously monitors the user’s activity and responds accordingly for greater safety.
Supportive resistance throughout stance phase provides optimal stability for walking with greater safety and less effort on all-terrain.
Maximum resistance stabilises knee, on both at and slopes, encouraging better posture and balanced loading to relieve pressure on sound limb and lower back.
Stance resistance engages during swing phase extension to ensure knee stability should the user stumble.
Knee resistance progressively increases with immediate support on the first step and increasing support with further knee flexion for enhanced control and safety when descending stairs or slopes.
Progressive hydraulic resistance ensures greater support and control to sit down with safety and confidence and more balanced loading across both limbs.
Knee flexion during swing phase varies according to walking speed. With microprocessor pneumatic swing control, Orion3 controls heel rise across a range of walking speeds for a more natural swing. The pneumatic spring also makes it easier to initiate swing, saving energy with every step and ensuring more natural knee flexion at lower speeds.
Orion3 releases high resistance just before the knee bends for optimal safety, easy knee flexion and reduced walking effort.
By sensing changes in walking speeds, Orion3 dynamically adapts pneumatic control in real time for a smooth, natural and energy efficient swing.*
Swing phase extension is damped in late swing to soften knee movement and prevent terminal swing impact.
*Studies have shown the reduced physiological cost of walking, with reduction in energy expenditure by up to 20% – please refer to our clinical compendium for further details.
