Bosch, T. de Looze, M. Stadler, K.S. Graf, E. O'Sullivan, L.W. Publication year 2018 Abstract The aim of this study was to evaluate the effect of a passive upper body exoskeleton on muscle activity, perceived musculoskeletal effort, local perceived pressure and subjective usability for a static overhead task. Eight participants (4 male, 4 female) held a load (0 kg and 2 kg) three times overhead for a duration of 30 s each, both with and without the exoskeleton. Muscle activity was significantly reduced for the Biceps Brachii (49%) and Medial Deltoid (62%) by the device for the 2 kg load. Perceived effort of the arms was significantly lower with the device for the 2 kg load (41%). The device did not have a significant effect on trunk or leg muscle activity (for the 2 kg load) or perceived effort. Local perceived pressure was rated below 2 (low pressure levels) for all contact areas assessed. Half of the participants rated the device usability as acceptable. The exoskeleton reduced muscle activity and perceived effort by the arms, and had no significant negative effect on the trunk and lower body with regards to muscle activity, perceived effort and localised discomfort. © 2018 Elsevier Ltd Subject LifeSP - Sustainable Productivity and EmployabilityELSS - Earth, Life and Social SciencesWork and EmploymentWorkplaceHealthy LivingMuscleBiceps brachiiContact areasLeg musclesLow pressuresLower bodyMuscle activitiesUpper bodiesUpper limbsExoskeleton (Robotics)AdultBiceps brachii muscleDeltoid muscleExoskeletonFemaleHumanHuman experimentHypobarismLeg muscleMaleMuscle functionTrunk To reference this document use: http://resolver.tudelft.nl/uuid:e90305a3-1530-4965-9eaa-9bdaac03d98f DOI https://doi.org/10.1016/j.apergo.2018.02.009 TNO identifier 787793 ISSN 0003-6870 Source Applied Ergonomics, 70, 148-155 Document type article Files To receive the publication files, please send an e-mail request to TNO Library.
