Powered Orthotic Exoskeleton Training in Stroke

A new and novel type of robotic-device (Keeogo, B-temia, Inc.) was developed to provide powered assistance at the knee for persons with stroke. This device provides assistance for both knee extension and knee flexion during ambulation, transfers to standing and sitting, in addition to ascending and descending stairs. As this device isn't able to fully control the movement, it requires the ability of the patient to stand and initiate stepping. The approach the Keeogo uses to monitor the desired movement in order to appropriately provide assistance. This promotes intuitive learning for the user, minimizing the amount of instruction and practice needed to effectively ambulate allowing users to independently ambulate within one session. This device does not restrict leg movement, so the user can side-step and walk backwards. However, it does not provide assistance during these movements.

Ambulation training will consist of mobility activities affecting daily life including: walking; squatting (or getting in and out of a chair); bending, kneeling or stooping (for picking an item up off of the floor); and ascending and descending stairs. Sessions will be monitored and tailored to the individual, based on their functional ability and to ensure their safety.
