Current clinical use and perceived impact of the sensory collapse test: A survey of peripheral nerve surgeons and hand therapists.

BACKGROUND

The Sensory Collapse Test (SCT) is a clinical maneuver used in the assessment of peripheral nerve compression. Despite being widely described, its actual use and perceived impact in clinical practice remain unclear.

OBJECTIVES

To evaluate the current clinical use of the SCT, factors associated with its adoption, and its perceived influence on clinical decision-making among professionals involved in peripheral nerve care.

METHODS

An international, web-based survey was conducted among clinicians involved in peripheral nerve surgery and hand therapy. The questionnaire assessed familiarity with the SCT, training background, frequency of use, confidence in its diagnostic value, and perceived impact on clinical decision-making. Descriptive statistics and comparative analyses were performed, including subgroup analyses and multivariable logistic regression to identify factors associated with SCT use.

RESULTS

A total of 136 responses from 38 countries were analyzed. Most respondents were familiar with the SCT (86%), although its use varied: 55% reported frequent use and 11% reported never using the test. Formal training and greater professional experience were independently associated with SCT use (p < 0.05). Confidence was higher when the SCT was used as a complementary rather than a standalone diagnostic tool and correlated positively with frequency of use. Frequent users more commonly reported that the SCT influenced clinical decision-making, particularly regarding localization of nerve compression and surgical planning.

CONCLUSIONS

The SCT is widely recognized but inconsistently used. Its adoption is associated with training and experience, and it is generally perceived as a useful complementary tool. Further studies are needed to better define its diagnostic accuracy and clinical role.
