A Study of Relationships Between Family Members Using Familial Correlations
<p>Familial correlations measure the resemblance between family members and are used in many fields of study including epidemiology, genetics, heredity, and psychology. Here, an analysis of familial correlations where male and female children of the same family can have different correlations in …

Reliability of electromyography detection systems for the pelvic floor muscles
… determined using a variety of measures including intraclass correlation coefficients (ICC), coefficients of variation (CV) and mean absolute difference (MAD). The reliability of the different devices was compared using the MAD normalized to average signal amplitude (nMAD). The results indicated …

Use of Technology for Physical Activity Assessments and Intervention Applications
… Good overall reliability were found (all intraclass correlation coefficients > 0.93). Generalizability theory coefficients showed lower values for the running speed (0.70) versus the walking speeds (all > 0.84) with the majority of the variability derived from the participant (68% - 88%). …
