We appreciate Dr Sucher's excellent comments and clarifications regarding our review article on using osteopathic manipulative medicine (OMM) for treating patients with carpal tunnel syndrome (CTS).1 Dr Sucher's CTS research in this area was pioneering for the osteopathic medical profession and led us to review the current literature, including his research.

Dr Sucher rightfully notes that Figure 2 in our article1 is oversimplified. We illustrated the cross-section of the carpal tunnel for the purpose of demonstrating the close proximity of carpal tunnel structures. We had no intention of misleading the readers.

We also agree with Dr Sucher on the importance of musculoskeletal ultrasonography (US) in diagnosing CTS, with its benefits of noninvasiveness and short examination times being demonstrated within the past decade. Musculoskeletal US has shown its effectiveness in confirming and excluding cases of CTS, as well as in demonstrating anatomic lesions. However, a recent meta-analysis demonstrated the diagnostic sensitivity and specificity of musculoskeletal US for CTS to be 78% and 87%, respectively, while the sensitivity and specificity of electrodiagnostic studies are 85% and 95%, respectively.2,3 In comparison to electrodiagnostic studies, musculoskeletal US cannot grade the severity of CTS, which can lead to consideration of invasive or more aggressive treatment options, such as surgical intervention.4,5 Furthermore, this approach can result in a “higher cost,” because if musculoskeletal US is used as a first-line diagnostic tool, electrodiagnostic studies will most likely need to be conducted for confirmation and classification of CTS severity.

We thank Dr Sucher for his correction and description of the Opponens roll maneuver. Interestingly, our own studies have shown that an individual with CTS can self-administer the Opponens roll maneuver with improvement of CTS symptoms (unpublished data).

With the increasing incidence of CTS, further research is warranted in investigating the use of OMM for patients with CTS.6 We agree with Dr Sucher that research in musculoskeletal US will play an important future role in the application of OMM for such patients.
