Painful leg ulceration: a prospective, longitudinal cohort study.
This study aimed to explore the relationship between pain mechanism, pain intensity, and leg ulcer characteristics using a 6-month longitudinal cohort study in a community setting in the north of England. Patients with leg ulceration referred consecutively to district nurses were invited to participate (n=96). The main outcome measures were pain intensity using daily visual analogue scores, leg ulcer characteristics (etiology, size, location, duration), and LANSS (Leeds Assessment of Neuropathic Symptoms and Signs). Results suggested that type, duration, position, and size of the leg ulcer had no effect on average daily pain scores. Using the LANSS questionnaire, 43.5% of respondents reported symptoms suggestive of a neuropathic mechanism to their pain. Patients with neuropathic symptoms had higher average daily pain scores (p<0.001). Fewer people had healed ulcers at 6 months with neuropathic symptoms compared with those with no neuropathic symptoms (30.8 vs. 52.1%). It would seem that the severity of pain can not be predicted by the type, size, position, or duration of ulceration. Patients who scored positively for neuropathic symptoms had higher average daily pain scores and fewer had healed leg ulcers at 6 months compared with those who did not experience neuropathic signs and symptoms.
