Introduction<\/h3>\n<p>Most chronic pelvic and perineal pain is accompanied by an inability to remain seated for long periods, with obvious repercussions on quality of life (meals, travel and work). One of the first medical recommendations is to use a seat that off-loads the painful points. Yet no study has demonstrated the effectiveness of such seats in this population. It is therefore necessary to consider developing suitable devices and evaluating them rigorously in patients with chronic pelvic-perineal pain.<\/p>\n<p>The APORIA seat is intended to provide lasting relief of sitting pain in the sacral, coccygeal and perineal areas and lasting comfort for people with pelvic-perineal pain. This product is not a medical device.<\/p>\n<p>This pilot study, outside clinical research, aims to obtain feedback from potential users on the benefits and comfort of the APORIA\u00ae seat in order to identify possible improvements.<\/p>\n<p>This is the final report of the study, including the study results.<\/p>\n<h4>1. Reminder of the study objectives<\/h4>\n<p>The main objective of this survey was user feedback on the use of the APORIA chairs by patients with chronic pelvic-perineal pain, by assessing the sitting comfort of the APORIA chairs compared with the other chairs in the waiting room of the urology department at CHU de Nantes.<\/p>\n<p>In addition to the main objective of the study, population characterization data (sex, BMI, age, d\u00e9partement of residence\u2026) were collected; the results are presented for the total sample (95 questionnaires) in the first part of the report.<\/p>\n<p>The questionnaire covers all the evaluation criteria of the study, and this report presents all the data collected with this questionnaire during the 5 months of testing of the APORIA chairs.<\/p>\n<h4>2. Information on the products studied<\/h4>\n<p>The partner is a young French company specializing in the design, development and marketing of comfort and well-being products. The APORIA seats are developed by the company Blueportance. The APORIA chairs are intended to provide lasting relief of sitting pain in the sacral, coccyx and perineal areas and, in particular, lasting comfort for people with pelvic-perineal pain.<\/p>\n<p>This product consists of hard parts articulated with one another and includes in particular:<\/p>\n<ul>\n<li>1 thermoformed base<\/li>\n<li>4 thermoformed pads<\/li>\n<li>Foam layers providing support and comfort on top of the pads,<\/li>\n<\/ul>\n<details class=\"bp-ps-orig\"><summary>View the original page (page 4 of the report, in French)<\/summary><img decoding=\"async\" alt=\"Pelvi-Seat study, CHU de Nantes, page 4: Introduction: chronic pelvic and perineal pain often makes prolonged sitting impossible; no study has evaluated off-loading seats; objectives of the study of the Aporia\u00ae seat.\" height=\"2000\" loading=\"lazy\" src=\"https:\/\/blueportance.com\/wp-content\/uploads\/etude-pelvi-seat-chu-nantes-page-04.webp\" width=\"1414\"\/><\/details>\n<p class=\"bp-ps-cap\"><strong>Page 4<\/strong> \u2014 Introduction: chronic pelvic and perineal pain often makes prolonged sitting impossible; no study has evaluated off-loading seats; objectives of the study of the Aporia\u00ae seat.<\/p>\n<\/section>\n<section aria-label=\"Report page 5\" class=\"bp-ps-page\" id=\"page-05\">\n<p class=\"bp-ps-pnum\">Report, page 5 of 48 \u2014 Products studied and methodology<\/p>\n<ul>\n<li>1 cushion cover (83% cotton, 14% polyester, 3% elastane) \/ or four covers, one on each pad fitted with its foam;<\/li>\n<li>2 wedges<\/li>\n<\/ul>\n<p>For the purposes of the study, the Aporia seat was specifically mounted on a height-adjustable base.<\/p>\n<p>The company Blueportance provided two APORIA seats with different ergonomic characteristics: APORIA N\u00b01 (\u201cChair 2\u201d in the study), designed to relieve pudendal pain, and APORIA N\u00b02 (\u201cChair 4\u201d in the study), designed to relieve coccyx pain.<\/p>\n<h4>3.

The preferred chair is APORIA N\u00b02 with 43.6% of votes, followed by APORIA N\u00b01 with 34.6%, versus 10.9% of votes for the hard and padded chairs.<\/p>\n<p>The APORIA N\u00b01 and APORIA N\u00b02 seats also appear to offer greater comfort than the cushions or other products used by patients in daily life.<\/p>\n<p>Regarding pain relief, the APORIA N\u00b01 seat appears to relieve cluneal and pudendal pain, and the APORIA N\u00b02 seat appears to relieve coccyx pain, but it is difficult to draw conclusions about other types of pain patients may suffer from. The APORIA N\u00b01 and APORIA N\u00b02 seats were developed to relieve pudendal and coccygeal pain respectively, and the results of this study point in that direction.<\/p>\n<p>However, the evaluation time is limited, and a study in real-life conditions (at work, at the patient\u2019s home) with a more robust methodology (crossover, randomized) is needed to confirm the value of using the APORIA seats for patients with chronic pelvic-perineal pain related to the sitting position.<\/p>\n<details class=\"bp-ps-orig\"><summary>View the original page (page 47 of the report, in French)<\/summary><img decoding=\"async\" alt=\"Pelvi-Seat study, CHU de Nantes, page 47: Discussion and conclusion: in the complete sample (55 patients), Aporia\u00ae N\u00b02 preferred by 43.6% and Aporia\u00ae N\u00b01 by 34.6%, versus 10.9% for each of the other two chairs; Aporia\u00ae N\u00b01 appears to relieve pudendal and cluneal pain, Aporia\u00ae N\u00b02 coccyx pain; a randomized real-life study is still needed.\" height=\"2000\" loading=\"lazy\" src=\"https:\/\/blueportance.com\/wp-content\/uploads\/etude-pelvi-seat-chu-nantes-page-47.webp\" width=\"1414\"\/><\/details>\n<p class=\"bp-ps-cap\"><strong>Page 47<\/strong> \u2014 Discussion and conclusion: in the complete sample (55 patients), Aporia\u00ae N\u00b02 preferred by 43.6% and Aporia\u00ae N\u00b01 by 34.6%, versus 10.9% for each of the other two chairs; Aporia\u00ae N\u00b01 appears to relieve pudendal and cluneal pain, Aporia\u00ae N\u00b02 coccyx pain; a randomized real-life study is still needed.<\/p>\n<\/section>\n<section aria-label=\"Report page 48\" class=\"bp-ps-page\" id=\"page-48\">\n<p class=\"bp-ps-pnum\">Report, page 48 of 48 \u2014 Signature of the study lead<\/p><figure class=\"bp-ps-fig bp-ps-sign\"><div class=\"bp-ps-crop\" style=\"aspect-ratio:473.0\/259.0;border:0\"><img decoding=\"async\" alt=\"Signature block of the Pelvi-Seat final report: Study lead \u2014 Name: Dr Amelie SENEAU LEVESQUE \u2014 Date: December 13, 2023 \u2014 Handwritten signature.
