The magnitude of humeral torsion (HT) affects the internal and external rotation
range of motion at the shoulder. Currently imaging is required to quantify the HT
angle, however, factors such as cost and non-availability of imaging to
musculoskeletal clinicians limits its use. The aim of this study was to examine
the validity of palpation of the bicipital tuberosities as an alternative to
imaging for quantifying HT angles. The bicipital-forearm angle, an indirect
measure of HT, was measured using palpation and real-time ultrasound imaging in
25 subjects. The agreement among the two methods was excellent with the
Intraclass Correlation Coefficient (3,k) = 0.92, and the mean difference between
the two methods was -0.2 degrees (SD 4.1 degrees ) with 95% limits of agreement
of -8.3 degrees to 7.9 degrees . Pearson's correlation coefficient (r) among the
two methods was 0.85. In a clinical setting, palpation appears to be a practical
alternative to US imaging for measuring HT.
