A review is given of the development of methods for testing normal and abnormal somatosensory functions in pain patients. In pain research and management it is important to record not only quantitative but also qualitative aberrations of evoked perceptions. In neuropathic pain, such aberrations may constitute a significant part of the patients’ symptomatology and can be assessed in statistical terms. In addition to abnormal quality and magnitude of evoked perceptions, neuropathic patients report abnormal spread or dislocation of pain, as well as a temporal distortion with abnormal latency, summation of repeated stimuli, and aftersensation. Various methods for testing mechanoreception (touch, pointed touch, tactile discrimination, vibration and pressure) and thermosensibility (perception thresholds, growth functions supraliminally, quality) are described and their uses in clinical diagnosis are illustrated in neuropathic pain patients. Central to somatosensory testing is that suprathreshold hypo- or hyperfunctions may both exist combined with normal threshold, with increased threshold or with lowered thresholds.
