Psycho-metric vs Muscle-metric Parameters Similarity.

<p>Concordance between the shape of the psycho and muscle metric curves as well as between thresholds. Each bar shows the across subjects averaged difference values (perceptual—muscular) between the psychometric and muscle-metric datasets with 95% confidence intervals (CI). Zero difference values (horizontal dashed line) indicates a perfect match between psychometric and muscle-metric curves as well as relative thresholds. PSE difference below zero indicates that muscles tended to have higher thresholds than perceptual ones. Curve parameters difference mean value and CIs were averaged across 9 subjects (those with <i>R</i>^<i>2</i> <i>merged ></i> 0.5 and <i>R</i>^<i>2</i> <i>psy ≥</i> 0.6, Tables <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0152552#pone.0152552.t001" target="_blank">1</a> and <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0152552#pone.0152552.t002" target="_blank">2</a>). PSE differences were averaged across 11 subjects (<i>R</i>^<i>2</i> <i>merged ></i> 0.5, values in bold <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0152552#pone.0152552.t002" target="_blank">Table 2</a>) whose thresholds and CIs were calculated by considering PSE values from reversals when <i>R</i>^<i>2</i> <i>psy</i> was lower than 0.6.
