Robotic orthoses for body weight-supported treadmill training.

BWSTT has become an accepted standard of care in gait rehabilitation methods. This type of locomotor training has many functional benefits, but the physical labor costs are considerable. To reduce therapist effort and improve the repeatability of locomotor training, three groups have developed commercially available robotic devices for assisted stepping. The purpose of these robotic devices is to augment locomotor rehabilitation by decreasing therapist manual assistance, increasing the amount of stepping practice, while decreasing therapist effort. Current clinical studies have yielded positive and promising results in locomotor rehabilitation inpatients with neurologic impairments of stroke or SCI. The potential benefits from robotic technology are significant for clinical use and research. As further research is conducted, rehabilitation therapists and patient outcomes will be able to contribute to the development of current and future technologies.
