Although the PDFR after complete spinal transection is well described, information regarding the more clinically relevant incomplete spinal contusion injury model is limited. This study examined, using two-dimensional (2D) kinematic analysis, the relationship between the PDFR and degree of white matter sparing (WMS). Male Wistar rats received a T9 contusion with varying degrees of impactor forces. Weekly kinematic recordings of the PDFR were made 3\u20138 weeks postinjury. Sexual reflex components examined included maximum angle of penile dorsiflexion, total penile event duration, and penile ascent speed. Post hoc comparison between animals grouped based upon injury severity (moderate\u2013severe: 13.33%\u201317.15% WMS\n                      <jats:italic toggle=\"yes\">vs<\/jats:italic>\n                      moderate: 20.85%\u201333.50% WMS) indicated PDFR effects. Specifically, the numbers of animals with more moderate contusions having data points above the median in both maximum angle of penile dorsiflexion and penile ascent speed were significantly lower than animals with more severe injuries. Total penile event duration was also affected but only at more chronic time points (6\u20138 weeks). Thus, 2D kinematic analysis of the PDFR allows for more consistent and quantifiable analysis of the subtle differences that can occur between injury severity groups in the rat contusion model.\n                    <\/jats:p>\n                  <\/jats:sec>","DOI":"10.4103\/aja.aja_1_20","type":"journal-article","created":{"date-parts":[[2020,4,21]],"date-time":"2020-04-21T08:31:31Z","timestamp":1587457891000},"page":"30-35","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":3,"title":["Kinematic analysis of penile reflexes in a rat model of spinal cord injury"],"prefix":"10.4103","volume":"23","author":[{"given":"Casey J","family":"Steadman","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sai S","family":"Vangoor","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Charles H","family":"Hubscher","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"R1-6-20240829","doi-asserted-by":"crossref","first-page":"36","DOI":"10.1038\/sc.2008.121","article-title":"International standards to document remaining autonomic function after spinal cord injury","volume":"47","author":"Alexander","year":"2009","journal-title":"Spinal Cord"},{"key":"R2-6-20240829","doi-asserted-by":"crossref","first-page":"541","DOI":"10.1016\/S0003-9993(96)90292-0","article-title":"Sexual adjustment and quality of relationship in spinal paraplegia: a controlled study","volume":"77","author":"Kreuter","year":"1996","journal-title":"Arch Phys Med Rehabil"},{"key":"R3-6-20240829","doi-asserted-by":"crossref","first-page":"338","DOI":"10.1038\/sj.sc.3101978","article-title":"Long-term effects of spinal cord injury on sexual function in men: implications for neuroplasticity","volume":"45","author":"Anderson","year":"2007","journal-title":"Spinal Cord"},{"key":"R4-6-20240829","doi-asserted-by":"crossref","first-page":"507","DOI":"10.1093\/humupd\/dmt029","article-title":"The spinal control of ejaculation revisited;
