AbstractThirty-four patients with various forms of neuropathic pain have been examined with respect to two parameters of dynamic mechanical allodynia: the effect of repetitive stimulation on pain intensity; and refractory period. Pain intensity increased with repetitive stimulation ('windup') in most patients with neuropathic pain of peripheral origin, while it was not observed in patients with central neuropathic pain. While a non-responsive period occurs after tactile allodynic elicitation in patients with trigeminal neuralgia (Kugelberg and Lindblom, 1959), it was not seen in any case of neuropathic pain, including trigeminal neuropathy. The findings have implications for diagnosis, and require pathophysiological elucidation in terms of revealed differences.
