Jonathon Schofield, Ph.D. (Research Assistant)

Jonathon is a Research Assistant in the BLINC lab. In 2017, he completed his PhD. in Mechanical Engineering at the University of Alberta researching Upper limb prostheses and sensory feedback strategies. Prior, he completed his Masters degree in Structural Engineering in 2012 with hiss research investigating musculoskeletal biomechanics and orthotic design. Jonathon was a 2009 graduate of the Mechanical Engineering program at Lakehead University.

Research Interests:

Kinesthetic Sensory Feedback: Dexterous hand movement is dependent on motor output and sensory feedback. This is significantly altered in those with upper limb amputation as sensations of touch and movement (sensory feedback) are inherently lost with the limb. While operating upper limb prostheses, the absence of sensory feedback impedes use of the device by forcing reliance on vision and increasing the required conscience attention. The goal of my work is to establish a sensory interface for upper limb prostheses capable of providing natural, physiologically relevant movement feedback. My work involves the exploration of non-invasive methods to elicit sensations of movement in a patient’s missing limb, and to integrate these strategies with functional prostheses. My interests included analysis of potential feedback methods, feedback system development and design, as well as patient testing.
