Robotic exoskeletons for reengaging in everyday activities: promises, pitfalls, and opportunities.

Purpose: Media images and marketing materials suggest a future in which individuals with spinal cord injury (SCI) can utilize robotic exoskeletons to reengage in everyday activities, yet these narratives may not align with the current technological realities. The purpose of this paper is to present and describe the current use of robotic exoskeletons in rehabilitation and home settings and discuss the benefits and limitations of the devices.

Materials And Methods: We provide an overview of the features and limitations of the four robotic exoskeleton products (EKSO Bionics, ReWalk, Rex Bionics, and Indego) that are currently being used in in the United States in rehabilitation settings. We follow by suggesting ways that these devices fall short of fulfilling the promise of reengage in everyday activities in real-world life contexts.

Results And Discussion: Available devices appear to be better suited for rehabilitation settings than for home use. Device weight, the need for upper extremity supports, supervision requirements, and a limited range of movements are all issues that limit functionality and restrict opportunities for using such devices in real-world contexts. Designing the next generation of exoskeletons to be more useful in everyday life will require further collaboration among engineers, clinicians, and patients. Implications for Rehabilitation Exoskeletons offer the promise of allowing individuals with neurological injury to reengage in everyday activities from a standing position. Several exoskeleton devices are currently available for use in the United States. Weight of exoskeleton devices, the need for upper extremity supports, supervision requirements of hone units, and a limited range of movements are issues that restrict opportunities for using such devices in real-world contexts. Further development of exoskeleton technologies is warranted to improve the devices for real-world use.
