title: Interexaminer reliability of the deltoid and psoas muscle test.
abstract: OBJECTIVE
  To determine if 2 practitioners of differing skill levels could reliably agree on the presence of a weak or strong deltoid or psoas muscle.
  
  
  METHODS
  Interexaminer reliability study of 2 common muscle tests.
  
  
  METHODS
  Cohen kappa (unweighted) scores, observer agreement, and 95% confidence intervals (CIs).
  
  
  RESULTS
  The results showed that an experienced and a novice practitioner have good agreement when using repeated muscle test procedures on the deltoid ( kappa 0.62) and the psoas ( kappa 0.67).
  
  
  CONCLUSIONS
  The manual muscle test procedures using the anterior deltoid or psoas showed good interexaminer reliability when used by an experienced and a novice user. These techniques may be used between practitioners in multidoctor assessment/management programs.
