However, efficacy of IDET for the treatment of referred leg pain has not been examined. This study was performed to assess the long\u2010term efficacy of IDET for the treatment of referred leg pain in chronic discogenic LBP patients. Data were retrospectively analyzed as an IDET case series from January 1999 to December 2000. The IDET procedure was performed at 1\u20133 symptomatic levels confirmed by pressure\u2010controlled discography. General pain outcome was evaluated by Visual Analog Scale (VAS). LBP and leg pain were assessed separately using five\u2010point pain scales (subsets of the North American Spine Society [NASS] LBP outcome assessment instrument: 0\u2003=\u2003no pain, 4\u2003=\u2003worst pain) at the 18\u2010month follow\u2010up. Among 129 patients who underwent IDET, 30 patients underwent subsequent back surgery and were excluded from the study, giving a total of 99 patients. Eighty\u2010three patients (83.8%) had leg pain without sciatica. Fifty\u2010two (52.5%), 21 (21.2%), and 8 (8.0%) patients showed LBP\u2003&gt;\u2003leg pain, LBP\u2003=\u2003leg pain and LBP\u2003&lt;\u2003leg pain, respectively. Fifty\u2010three out of 83 patients (63.9%) showed post\u2010IDET improvement in pain, with a mean VAS score of 3.28\u2003\u00b1\u20032.31. Thirty patients (36.1%) showed no improvement. A statistically significant (<jats:italic>P<\/jats:italic>\u2003&lt;\u20030.05) improvement in subjective back and referred leg pain was observed. Improvements in back and referred leg pain were well\u2010correlated (<jats:italic>r<\/jats:italic>\u2003=\u20030.721, <jats:italic>P<\/jats:italic>\u2003&lt;\u20030.01). A relatively large number of LBP patients who underwent IDET (84%) presented with referred leg pain without sciatica. The IDET procedure afforded improvements in leg pain that correlated well with improvements in back pain (0.75\/4 and 0.88\/4, respectively). These data suggest that IDET may relieve associated limb pain in chronic discogenic LBP patients.<\/jats:p>","DOI":"10.1111\/j.1533-2500.2004.04401.x","type":"journal-article","created":{"date-parts":[[2004,11,17]],"date-time":"2004-11-17T11:01:35Z","timestamp":1100689295000},"page":"281-285","source":"Crossref","is-referenced-by-count":15,"title":["Efficacy of IDET for Relief of Leg Pain Associated with Discogenic Low Back Pain"],"prefix":"10.1111","volume":"4","author":[{"given":"Richard","family":"Derby","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sang\u2010Heon","family":"Lee","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kwan Sik","family":"Seo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kerri","family":"Kazala","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Byung\u2010Jo","family":"Kim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mi Jung","family":"Kim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2004,11,17]]},"reference":[{"key":"e_1_2_7_2_2","doi-asserted-by":"publisher","DOI":"10.1097\/00002517-199003000-00009"},{"key":"e_1_2_7_3_2","doi-asserted-by":"publisher","DOI":"10.1097\/00007632-199707150-00015"},{"key":"e_1_2_7_4_2","first-page":"231","volume-title":"Bonica's Management of Pain.","author":"Coda B","year":"2001"},{"key":"e_1_2_7_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/0304-3959(93)90103-V"},{"key":"e_1_2_7_6_2","doi-asserted-by":"publisher","DOI":"10.1113\/jphysiol.1990.sp018137"},{"key":"e_1_2_7_7_2","doi-asserted-by":"publisher","DOI":"10.1097\/00007632-200212150-00007"},{"key":"e_1_2_7_8_2","first-page":"1605","article-title":"Radiating pain to the lower extremities caused by lumbar disk rupture without spinal nerve root involvement","volume":"16","author":"Milette PC","year":"1995","journal-title":"AJNR Am J Neuroradiol."},{"key":"e_1_2_7_9_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1525-1403.2000.00082.x"},{"key":"e_1_2_7_10_2","doi-asserted-by":"publisher","DOI":"10.1097\/00007632-200010150-00010"},{"key":"e_1_2_7_11_2","doi-asserted-by":"publisher","DOI":"10.1097\/00007632-200010150-00013"},{"key":"e_1_2_7_12_2","doi-asserted-by":"publisher","DOI":"10.1097\/00007632-200205010-00017"},{"key":"e_1_2_7_13_2","doi-asserted-by":"crossref","first-page":"81","DOI":"10.2340\/165019771983158188","article-title":"A prospective study of low back pain in a general population.
