Sensory symptoms are crucial for the diagnosis of carpal tunnel syndrome (CTS). We have studied the spectrum of sensory symptoms in 67 cases of neurophysiologically confirmed CTS in Singapore and investigated the correlation of semi-quantitative clinical ('Historical-Objective') and neurophysiological ('Bland') scales. The range of sensory symptoms was large. The more frequent use of the terms 'woodenness' and 'aching' rather than 'pins and needles' suggests racial and cultural differences in symptom expression, or recognition of previously ignored descriptors. 'Numbness' (97%) was the most common descriptive symptom, followed by 'tingling' (81%), 'tightness' (60%), 'aching' (45%), 'woodenness' (39%) and 'pins and needles' (33%). Less common were 'deadness' (27%), prickling (24%), and cramp-like pain (18%). Uncommon sensations included 'jabbing' (10%), 'shooting pain' (10%), 'stabbing' (9%), 'tight-band like pressure' (9%), 'cold' (8%), 'crushing' (6%) and 'burning' (6%). The semi-quantitative clinical and neurophysiological scales correlated well (Pearson 0.645, P<0.001).
