Subgroups of patients based on sensory symptoms. To identify relevant subgroups of patients with a characteristic symptom profile a hierarchical cluster analysis was performed in patients with painful diabetic neuropathy and fibromyalgia. Each cluster is represented by the patterns of questionnaire scores (adjusted individual mean) thus showing the typical pathological structure of the respecting group. By using this approach five clusters with distinct symptom profiles could be detected. Sensory profiles show remarkable differences in the expression of the symptoms.

% : frequency of occurrence, DPN : painful diabetic neuropathy, FM : fibromyalgia.
