Brief Summary:
The purpose of this study is to assess and validate the clinical criteria of sensitization ("Convergences PP criteria") selected by the expert consensus with neurophysiological sensory testing.

Condition or disease Intervention/treatment Phase
Chronic Pelvic Pain Chronic Perineal Pain Other: Sensory testing of lower urinary tract. Other: Sensory testing of lower rectal tract Other: Sensory testing of vulva muscles Other: Sensory testing of pelvic muscles Not Applicable

Detailed Description:
Some patient with chronic pelvic or perineal pain, present complex manifestations, comprising pain and dysfunction which does not involved a single organ. The gap between clinical symptoms and pathological signs is a constant feature of these pain syndromes. A possible explanation for these pain syndromes is central sensitization. This sensitization is defined by decrease nociceptive thresholds, a more intense and more prolonged response to nociceptive stimulus, and spatial extension of the painful area. It has been defined by international expert consensus in 2016 a clinical evaluation tool with 10 criteria for sensitization diagnosis: Convergences PP criteria. The aim of this study is to objectivize lower threshold, spatial and temporal diffusion of pain in women with chronic pelvic or perineal pain with sensitization (Convergences PP criteria > 5) compared to women without sensitization (Convergences PP criteria < 5). A sensory testing of lower urinary tract, lower rectal tract, vulva and pelvic muscles will be achieved.

    Identification of lower pain perception thresholds in women with chronic pelvic or perineal pain with sensitization (Convergences PP criteria > 5) compared to women without sensitization (Convergences PP criteria < 5) for each of the 4 neurophysiological testing.

  3. Comparison of state anxiety [ Time Frame: 1 month after inclusion in the study ]
    Comparison of state anxiety between women with chronic pelvic or perineal pain with sensitization (Convergences PP criteria > 5) and without sensitization (Convergences PP criteria < 5).

  4. Comparison of depression [ Time Frame: 1 month after inclusion in the study ]
    Comparison of depression between women with chronic pelvic or perineal pain with sensitization (Convergences PP criteria > 5) and without sensitization (Convergences PP criteria < 5).

  5. Comparison of catastrophizing [ Time Frame: 1 month after inclusion in the study ]
    Comparison of catastrophizing between women with chronic pelvic or perineal pain with sensitization (Convergences PP criteria > 5) and without sensitization (Convergences PP criteria < 5).
