Diagnostic consequence of using either the contralateral side or normative data from healthy volunteers.

The interpretation of sensory function and its clinical manifestation at the affected side using the contralateral side or reference values from healthy volunteers. The observation at the affected side and contralateral side indicate the sensory response for a Quantitative Sensory Testing (QST) parameter in patients. Clinical results using the contralateral side as reference or healthy volunteers as reference indicate sensory interpretation for the affected side. ‘0’ indicate normal sensory function, ‘+’ indicate sensory gain such as hyperalgesia/allodynia, ‘−’ indicate sensory loss such as hypoesthesia, ‘++’ or ‘− −’ indicate overestimation of sensory gain or sensory loss, respectively.
