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.

Study Design

Interexaminer reliability study of 2 common muscle tests.

Main Outcome Measures

Cohen κ (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 (κ 0.62) and the psoas (κ 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.
