Materials and Methods: The medical records of 218 patients, who were diagnosed with lumbosacral radiculopathy and treated with a TFESI, were reviewed in this retrospective study. A mixture of corticosteroid, lidocaine, and hyaluronidase was injected during TFESI. Patients with &gt;50% pain relief on the numerical rating scale compared with the initial visit constituted the good responder group. Demographic, clinical, MRI, and electrodiagnostic data were collected to assess the predictive factors for short-term outcomes of the TFESI. Results: A multivariate logistic regression analysis demonstrated that a shorter duration of symptoms and a positive sharp wave (PSW)\/fibrillation (Fib) observed in electrodiagnostic study (EDx) increased the odds of significant improvement 2\u20134 weeks after the TFESI. Conclusions: Shorter duration of symptoms and PSW\/Fib on EDx were predictors of favorable short-term response to TFESI.<\/jats:p>","DOI":"10.3390\/medicina55050162","type":"journal-article","created":{"date-parts":[[2019,5,20]],"date-time":"2019-05-20T11:05:07Z","timestamp":1558350307000},"page":"162","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Factors Predicting Favorable Short-Term Response to Transforaminal Epidural Steroid Injections for Lumbosacral Radiculopathy"],"prefix":"10.3390","volume":"55","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1256-7800","authenticated-orcid":false,"given":"Dong Yoon","family":"Park","sequence":"first","affiliation":[{"name":"Department of Rehabilitation Medicine, Graduate School, The Catholic University of Korea, Seoul 06591, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5614-4175","authenticated-orcid":false,"given":"Seok","family":"Kang","sequence":"additional","affiliation":[{"name":"Department of Physical Medicine and Rehabilitation, Korea University Guro Hospital, Seoul 08308, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joo Hyun","family":"Park","sequence":"additional","affiliation":[{"name":"Department of Rehabilitation Medicine, Seoul St. Mary\u2019s Hospital, College of Medicine, The Catholic University of Korea, Seoul 06591, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,5,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"20","DOI":"10.5271\/sjweh.2767","article-title":"Previous back syndromes and present back symptoms in concrete reinforecment workers","volume":"4","author":"Lehtinen","year":"1978","journal-title":"Scand.
