Devices to prevent repetitive strain injuries should take into account bony characteristics determining the behaviour of the interosseous membrane (IOM) in supination, neutral position, and pronation of forearm and hand

Abstract

The use of vertical PC-mice in “handshake” positions, although stated equivalent to other devices, should be re-evaluated in view of the observed interosseous membrane tautness that our in vitro study demonstrated. As most thumb and index finger long muscles -agonists and antagonists alike - do originate from this forearm interosseous membrane, undue strains simultaneously caused by opposing muscles in using vertical PC-mice may elicit problems in vivo.
