| Abstract: | The assessment of muscle health is of paramount importance, as the loss of muscle mass and strength can affect performance. Two non-invasive tools that have been found to be useful in this are the MyotonPRO and rehabilitative ultrasound imaging, both have shown to be reliable in previous studies many of which conducted by the research team. This study aims to determine the reliability of previously unassessed local body structures and to determine their minimal detectable changes (MDC) to support both researchers and clinicians. Twenty healthy participants were recruited to determine the reliability of seven skin positions out of a previously established protocol. Reliability was determined between three independent raters, and day to day reliability was assessed with one rater a week apart. Intraclass Correlation Coefficients (ICC) between raters and between days for tissue stiffness, tone and elasticity range from moderate to excellent (ICC 0.52-0.97), with most good or excellent. ICCs for subcutaneous thickness between days was good or excellent (ICC 0.86-0.91) and moderate to excellent between raters (ICC 0.72-0.96), in muscles it was moderate to excellent between raters and days (ICC 0.71-0.95). The protocol in this study is repeatable with overall good reliability, it also provides established MDC values for several measurement points. |
