Abstract

<abstract abstract-type="main"> <title>ABSTRACT</title> <sec id="mus24454-sec-0001" sec-type="section"> <title>Introduction</title> <p>In this study, we analyzed the crosstalk in mechanomyographic (MMG) signals generated by the extensor digitorum (ED), extensor carpi ulnaris (ECU), and flexor carpi ulnaris (FCU) muscles of the forearm during wrist flexion (WF) and extension (WE) and radial (RD) and ulnar (UD) deviations.</p> </sec> <sec id="mus24454-sec-0002" sec-type="section"> <title>Methods</title> <p>Twenty right‐handed men (mean ± SD age = 26.7 ± 3.83 years) performed the wrist postures. During each wrist posture, MMG signals were detected using 3 accelerometers. Peak cross‐correlations were used to quantify crosstalk.</p> </sec> <sec id="mus24454-sec-0003" sec-type="section"> <title>Results</title> <p>The level of crosstalk ranged from 1.69 to 64.05%. The wrist postures except the RD did not influence the crosstalk significantly between muscle pairs. However, muscles of the forearm compartments influenced the level of crosstalk for each wrist posture significantly.</p> </sec> <sec id="mus24454-sec-0004" sec-type="section"> <title>Conclusions</title> <p>The results may be used to improve our understanding of the mechanics of the forearm muscles during wrist postures. <italic>Muscle Nerve</italic><bold>51</bold>: 899–906, 2015</p> </sec> </abstract>
