This study aimed to provide quantitative activation data for muscles of the forearm during pronation and supination while using a power grip. Electromyographic data was collected from 15 forearm muscles in 11 subjects while they performed maximal isometric pronating and supinating efforts in nine positions of forearm rotation. Biceps brachii was the only muscle with substantial activation in only one effort direction. It was significantly more active when supinating (µ = 52.1%, SD = 17.5%) than pronating (µ = 5.1%, SD = 4.8%, p < .001). All other muscles showed considerable muscle activity during both pronation and supination. Brachioradialis, flexor carpi radialis, palmaris longus, pronator quadratus and pronator teres were significantly more active when pronating the forearm. Abductor pollicis longus and biceps brachii were significantly more active when supinating. This data highlights the importance of including muscles additional to the primary forearm rotators in a biomechanical analysis of forearm rotation. Doing so will further our understanding of forearm function and lead to the improved treatment of forearm fractures, trauma-induced muscle dysfunction and joint replacements.

Solutions for the problem of long-term unemployment are increasingly shaped by neoliberally-informed logics of activation and austerity. Because the implications of these governing frameworks for everyday life are not well understood, this pilot study applied a critical occupational science perspective to understand how long-term unemployment is negotiated within contemporary North American socio-political contexts. This perspective highlights the implications of policy and employment service re-configurations for the range of activities that constitute everyday life. Methods: Using a collaborative ethnographic community-engaged research approach, we recruited eight people in Canada and the United States who self-identified as experiencing long-term unemployment. We analyzed interviews …
