In this work, we outline how new methods in real-time prediction learning provide an approach to one of the principal open problems in multi-function myoelectric control—robust, ongoing, amputee-specific adaptation. Techniques from reinforcement learning and general value functions are applied to learn and update predictions during continuing human interactions with multi-function robotic appendages. Tests were performed with a targeted motor and sensory reinnervation amputee subject and non-amputee participants. Results show that this online prediction learning approach is able to accurately anticipate a diverse set of human and robot signals by more than two seconds, and at different levels of temporal abstraction. These methods allow predictions to be adapted during real-time use, which is an important step toward the ...

Research paper thumbnail of A scoping review on heterogeneity in rehabilitation research: implications for return to duty in a military population

The objectives of this scoping review were to review rehabilitation studies that used a heterogeneous group in a civilian or military population, and to discuss the impact of heterogeneity on participation outcomes such as return to duty in the Canadian Armed Forces. Methods: Literature search resulted in extraction of 37 articles, which were sorted according to degree of heterogeneity and type of outcomes examined. Results: The largest number of studies pertained to civilians ( n=26), followed by military ( n=10), and Veterans ( n=1). We found various degrees of heterogeneity in population, setting, intervention, and outcome in these studies. Discussion: Studies extracted seemed to show a superior positive outcome in return to work/duty when the group was heterogeneous. Military rehabilitation studies examining return to duty tended...

However, evaluation is limited by a lack of understanding of the essential features of human-prosthesis behavior and by an absence of consistent task protocols.

Discussion: Studies extracted seemed to show a superior positive outcome in return to work/duty when the group was heterogeneous. Military rehabilitation studies examining return to duty tended to include a highly heterogeneous population. Future studies pertaining to return to work/duty and using a heterogeneous group should include a wide range of outcomes in the domains of the International Classification of Functioning, Health and Disease. Potential economic benefits in using a heterogeneous-based intervention are also discussed, along with implications for the Canadian Armed Forces.
