Visual feedback on high-density surface electromyography to enhance human performance

Advances in signal processing techniques have allowed real-time processing of the spatial activation of muscle activity. Thus visual information about the topographical distribution of muscle activity can be provided to an individual by assigning different colour intensities to regions with higher or lower activity. We are currently exploring the use of visual feedback on high-density surface electromyography to induce a re-organisation of muscle activity in asymptomatic people with the aim of enhancing human performance. This application has potential for clinical use to facilitate improved muscle coordination in people with chronic pain.

Spinal Mechanisms of Motor Learning and Motor Control in Human

Traditionally, the spinal cord was considered as a pathway for the transaction of signals between the brain and the spinal cord. However, a growing body of evidence proposes an active role of the spinal cord in the acquisition of new motor skills, development of proficiency and motor control. Utilising electrophysiological and neuroimaging techniques, we are examining the spinal mechanisms involved in the control of posture, movement, and skilled motor learning. We are also interested in understanding how the brain and spinal cord interact when expectations about posture and movement are violated and how this interaction contributes to the precision of motor actions in humans.
