Open Access research with a real impact on health...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

Abstract

Improving our understanding of mechanisms driving thumb rotation could potentially advance the design of current upper limb prosthesis to incorporate powered thumb control increasing the dexterity of the device. This study investigates thumb rotation using high density surface electromyography (HD-sEMG) of extrinsic hand muscles. An apparatus was designed and developed to test thumb rotation. Relevant data were acquired during isometric voluntary contractions with a 20-40% of maximum voluntary contraction (MVC) performed by 7 healthy right-handed volunteers. Data were processed and analyzed. Analysis showed that, thumb position could be extracted using features extracted from the HDsEMG data recorded with high statistical significance. © 2013 IEEE.
