The team ran a pilot of the PIPPI programme in 2019 to assess how helpful it would be. 88% of those who completed the programme reported they felt an improvement.
Before beginning PIPPI, the average participant’s rating of their pain intensity was moderate-severe. Following completion, the average fell to the mild range with only one woman still rating her pain as severe and a year later none of the women reported severe pain.
Following the programme the group also reported a significant reduction in how much the pain interfered with their life.
Participants were also asked questions about how confident they felt that they could still achieve activities despite their pain. After completing PIPPI the group average improved from moderate to highest confidence.
Many women who live with pelvic pain report experiencing a high level of worry about their symptoms. Following the PIPPI course the average level of worry felt by the group fell from the moderate to mild range.
