Parameters of nervous conductivity associated with chronic pain syndrome in patients with interstitial cystitis and lumbalgia

47 patients with chronic pain syndrome were examined on the outpatient setting: 17 with bladder pain syndrome / interstitial cystitis (BPS/IC), 30 with lumbalgia. Control group was made up of 15 healthy volun-teers. Pain syndrome was evaluated with the Visual Analogue Scale (VAS). Electroneurography of nerve su-ralis evaluated latency, amplitude and conductivity speed. Nociceptive flexor reflex (NFR) test evaluated pain threshold (PT), reflex threshold (RT) and PT/RT index. The obtained electroneurography data indicated ab-sence of any nerve suralis neuropathy in both groups. Significantly lower pain threshold rates in both BPS/IC and lumbalgia patients comparing to the control – testified presence of neuropathic pain component. No signif-icant difference of neurophysiological parameters found in both patient groups could specify similarity in path- ogenesis of chronic pain syndrome of different localization
