the ankle orthosis for rehabilitation and mobility

The Hermes is an advanced ankle orthosis with a unique spring system that can generate freely designed angle-moment relations about the ankle. Generating negative stiffnesses can counterbalance the bodies own spasms giving the patient regained control of their foot, enhancing mobility in day to day life and allowing for continous rehabilitation during use.

How the ankle orthosis works

Plantarflexor spasticity in combination with dorsiflexor paresis cause equinus or equinovarus foot affecting safe mobility. Conventional ankle-foot orthoses (AFOs) are stiff, and support mobility by attaining foot clearance during swing, but at the cost of ankle motion, push off during gait, and activities requiring a mobile ankle, like dressing and car-driving.

Together with a consortium of research partners, InteSpring developed a novel negative stiffness AFO, called Hermes, to compensate for the spastic ankle joint stiffness, enabling the available dorsiflexor muscles to regain control.

rewalk exoskeleton for home use

The Hermes  is a personalized demonstrator prototype for home use, that allows tuning to a range of patients’ needs. For home use, the hinge is designed for safety and durability (covering rotating parts) and accommodates individual patients’ needs using personalized torque-angle characteristics.

With cross-sectional patient studies in lab setting currently underway, a “Validate and Transfer II” enables longitudinal studies with home use.

Improved ankle mobility reduces complications of spastic paresis (e.g., contractures, high energy expenditure), allows renewed muscular control, and secondarily lowers the limitations in activities, enhancing quality of life.
