To determine if 2 practitioners of differing skill levels could reliably agree on the presence of a weak or strong deltoid or psoas muscle.
Interexaminer reliability study of 2 common muscle tests.
Main Outcome Measures: Cohen j (unweighted) scores, observer agreement, and 95% confidence intervals (CIs).
The results showed that an experienced and a novice practitioner have good agreement when using repeated muscle test procedures on the deltoid (j 0.62) and the psoas (j 0.67).
