Development of a Vision-Guided Shared-Control System for Assistive Robotic Manipulators.

Sensors (Basel) 2022 Jun 8;22(12). Epub 2022 Jun 8.

Human Engineering Research Laboratories, VA Pittsburgh Healthcare System, Pittsburgh, PA 15206, USA.

Assistive robotic manipulators (ARMs) provide a potential solution to mitigating the difficulties and lost independence associated with manipulation deficits in individuals with upper-limb impairments. However, achieving efficient control of an ARM can be a challenge due to the multiple degrees of freedom (DoFs) of an ARM that need to be controlled. This study describes the development of a vision-guided shared-control (VGS) system and how it is applied to a multi-step drinking task. Read More

The Impact of Control Interface on Features of Heart Rate Variability.

Annu Int Conf IEEE Eng Med Biol Soc 2021 11;2021:7544-7550

Shared human-robot control for assistive machines can improve the independence of individuals with motor impairments. Monitoring elevated levels of workload can enable the assistive autonomy to adjust the control sharing in an assist-as-needed way, to achieve a balance between user fatigue, stress, and independent control. In this work, we aim to investigate how heart rate variability features can be utilized to monitor elevated levels of mental workload while operating a powered wheelchair, and how that utilization might vary under different control interfaces.

Locked-In Syndrome: Practical Rehabilitation Management.

PM R 2021 12 20;13(12):1418-1428. Epub 2021 Feb 20.

Shirley Ryan AbilityLab, Northwestern University Feinberg School of Medicine, Chicago, IL, USA.

Locked-in syndrome is a rare and devastating condition that results in tetraplegia, lower cranial nerve paralysis, and anarthria with preserved cognition, vertical gaze, and upper eyelid movements. Although acute management is much like that of any severe stroke, rehabilitation and recovery of these patients have not been previously described. Challenges relevant to this population include blood pressure management and orthostasis, timing and appropriateness of reinstating oral feeding, ventilatory support, decannulation after tracheostomy, bowel and bladder management, vestibular dysfunction, and eye care.
