Dynamic mechanical allodynia in the secondary hyperalgesic area in the capsaicin model-Perceptually similar phenomena as in painful neuropathy?

Introduction In order to develop valid experimental human pain models, i.e., models potentially reflecting mechanisms underlying certain expressions of clinical pain conditions, similarities and discrepancies of symptoms/signs must first and foremost be evaluated comparing the two.

Evidence-based practice: attitudes, knowledge and behaviour among allied health care professionals.

Objective: To explore dieticians', occupational therapists' and physical therapists' attitudes, beliefs, knowledge and behaviour concerning evidence-based practice within a university hospital setting.

Design: Cross-sectional survey.

Setting: University hospital.

The influence of brushing force and stroking velocity on dynamic mechanical allodynia in patients with peripheral neuropathy.

Recently we demonstrated brush-evoked allodynia to be a partially graded phenomenon since increased brushing length and number of strokes significantly increased the brush-evoked pain intensity. In this study the influence of stroking velocity and brushing force on dynamic mechanical allodynia was examined in 16 patients with peripheral neuropathy. Brush-evoked allodynia was induced by lightly stroking 60mm of the skin twice with a 16 mm wide brush while varying stroking velocity (10, 20, 30 mm/s) and brushing force (10, 20, 40 g).

On the repeatability of brush-evoked allodynia using a novel semi-quantitative method in patients with peripheral neuropathic pain.

Using a semi-quantitative method the repeatability of brush-evoked allodynia was examined within and between days in nine patients with spontaneous ongoing pain and dynamic mechanical allodynia due to peripheral neuropathy. In addition, the relationship between the intensity of spontaneous ongoing pain and the total brush-evoked pain intensity was addressed. The brush stimulus was applied in the innervation territory of the lesioned nervous structure by lightly stroking 60 mm of the skin four times with an 8 mm wide brush.

Dynamic mechanical allodynia: on the relationship between temporo-spatial stimulus parameters and evoked pain in patients with peripheral neuropathy.

The relationship between temporo-spatial stimulus parameters and evoked pain intensity as well as duration was examined in patients with peripheral neuropathy and brush-evoked allodynia, i.e. dynamic mechanical allodynia.
