The aim of this article is to study the long-term result of OECs for patients with complete chronic spinal cord injury (SCI). One hundred and eight patients suffered from complete chronic SCI were followed up successfully within the period of 3.47 \u00b1 1.12 years after OEC therapy. They were divided into two groups based on the quality and quantity of their rehabilitative training: group A ( n = 79) in sufficient rehabilitation (or active movement-target enhancement-neurorehabilitation therapy, AMTENT) and group B ( n = 29) in insufficient rehabilitation. All patients were assessed by using the American Spinal Injury Association (ASIA) standard and the International Association of Neurorestoratology Spinal Cord Injury Functional Rating Scale (IANR-SCIFRS). Thirty-one patients were evaluated by the tests of magnetic resonance imaging (MRI), electromyography (EMG), and paravertebral sensory evoked potential (PVSEP). We found the following. 1) According to ASIA and IANR-SCIFRS assessment for all 108 patients, averaged motor scores increased from 37.79 \u00b1 18.45 to 41.25 \u00b1 18.18 ( p &lt;0.01), light touch scores from 50.32 \u00b1 24.71 to 55.90 \u00b1 24.46 ( p &lt; 0.01), pin prick scores from 50.53 \u00b1 24.92 to 54.53 \u00b1 24.62 ( p &lt;0.01); IANR-SCIFRS scores increased from 19.32 \u00b1 9.98 to 23.12 \u00b1 10.30 ( p &lt;0.01). 2) The score changes in terms of motor, light touch, pin prick, and IANR-SCIFRS in group A were remarkably different (all p &lt; 0.01). The score changes in group B were remarkably different in terms of motor ( p &lt; 0.05) and IANR-SCIFRS ( p &lt; 0.01), but not light touch or pin prick ( p &gt; 0.05). 3) Comparing group A with group B, the increased scores in terms of motor, light touch, and pin prick were remarkably different (all p &lt; 0.01), but not IANR-SCIFRS ( p &gt; 0.05). 4) Fourteen of 108 patients (12.96%) became ASIA B from ASIA A; 18 of 108 (16.67%) became ASIA C from ASIA A. Nine of them (8.33%) improved their walk ability or made them rewalk by using a walker with or without assistance; 12 of 84 men (14.29%) improved their sex function. 5) MRI examinations were taken for 31 patients; there were no neoplasm, bleeding, swelling, cysts, neural tissue destruction or infection (abscess) or any other pathological changes in or around OEC transplant sites. 6) EMG examinations were done on 31 patients; 29 showed improvement and the remaining 2 had no change. PVSEP tests were performed in 31 patients; 28 showed improvements and the remaining 3 had no change. 7) No deterioration or complications were observed in our patients within the follow-up period. Our data suggest OEC therapy is safe and can improve neurological functions for patients with complete chronic SCI and ameliorate their quality of life; the AMTENT most likely plays a critical role in enhancing functional recovery after cell-based neurorestorotherapy.<\/jats:p>","DOI":"10.3727\/096368912x633734","type":"journal-article","created":{"date-parts":[[2012,7,9]],"date-time":"2012-07-09T18:37:29Z","timestamp":1341859049000},"page":"23-31","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":79,"title":["Long-Term Outcome of Olfactory Ensheathing Cell Therapy for Patients with Complete Chronic Spinal Cord Injury"],"prefix":"10.1177","volume":"21","author":[{"given":"Hongyun","family":"Huang","sequence":"first","affiliation":[{"name":"Center for Neurorestoratology, Beijing Rehabilitation Center, Beijing, P.R.
