We present the cases of two patients in whom the upper limb HAL-SJ was implemented 5 and 7 months postoperatively following elbow flexor reconstruction for BPI. They underwent elbow flexor reconstruction with intercostal nerve crossing-to-musculocutaneous nerve (ICN-MCN crossing) after BPI. Postoperative training using the upper limb HAL-SJ was started from the Medical Research Council (MRC) grade 1 elbow flexion power to MRC grade 3 once every week or every 2 weeks. Both patients could implement elbow training using the upper limb HAL-SJ even in MRC grade 1 of their elbow flexion power. Training with the upper limb HAL-SJ was performed safely and effectively in two patients with elbow flexor reconstruction with ICN crossing after BPI.<\/jats:p>","DOI":"10.1177\/2309499018777887","type":"journal-article","created":{"date-parts":[[2018,6,6]],"date-time":"2018-06-06T21:28:16Z","timestamp":1528320496000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":22,"title":["Robotic rehabilitation training with a newly developed upper limb single-joint Hybrid Assistive Limb (HAL-SJ) for elbow flexor reconstruction after brachial plexus injury: A report of two cases"],"prefix":"10.1177","volume":"26","author":[{"given":"Shigeki","family":"Kubota","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, Faculty of Medicine, University of Tsukuba, Ibaraki, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hideki","family":"Kadone","sequence":"additional","affiliation":[{"name":"Center for innovating Medicine Engineering (CIME), University of Tsukuba, Ibaraki, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yukiyo","family":"Shimizu","sequence":"additional","affiliation":[{"name":"Department of Rehabilitation Medicine, University of Tsukuba Hospital, Ibaraki, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuki","family":"Hara","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Faculty of Medicine, University of Tsukuba, Ibaraki, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tadashi","family":"Kubo","sequence":"additional","affiliation":[{"name":"Department of Rehabilitation Medicine, University of Tsukuba Hospital, Ibaraki, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroki","family":"Watanabe","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Faculty of Medicine, University of Tsukuba, Ibaraki, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yasushi","family":"Hada","sequence":"additional","affiliation":[{"name":"Department of Rehabilitation Medicine, University of Tsukuba Hospital, Ibaraki, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Naoyuki","family":"Ochiai","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Kikkoman General Hospital, Chiba, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoshiyuki","family":"Sankai","sequence":"additional","affiliation":[{"name":"Faculty of Systems and Information Engineering, University of Tsukuba, Ibaraki, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masashi","family":"Yamazaki","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Faculty of Medicine, University of Tsukuba, Ibaraki, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2018,6,6]]},"reference":[{"key":"bibr1-2309499018777887","doi-asserted-by":"publisher","DOI":"10.1016\/0363-5023(92)90451-T"},{"key":"bibr2-2309499018777887","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2010.04.025"},{"key":"bibr3-2309499018777887","doi-asserted-by":"publisher","DOI":"10.3171\/jns.1998.88.2.0266"},{"key":"bibr4-2309499018777887","doi-asserted-by":"publisher","DOI":"10.1016\/S0363-5023(89)80047-4"},{"key":"bibr5-2309499018777887","doi-asserted-by":"publisher","DOI":"10.1016\/0266-7681(93)90051-G"},{"key":"bibr6-2309499018777887","doi-asserted-by":"publisher","DOI":"10.1053\/jhsu.1999.0571"},{"issue":"3","key":"bibr7-2309499018777887","first-page":"483","volume":"48","author":"Smania N","year":"2012","journal-title":"Eur J Phys Rehabil Med"},{"issue":"11","key":"bibr8-2309499018777887","first-page":"1799","volume":"57","author":"Takahashi M","year":"1983","journal-title":"Nihon Seikeigeka Gakkai Zasshi"},{"key":"bibr9-2309499018777887","doi-asserted-by":"publisher","DOI":"10.1097\/01.prs.0000254859.51903.97"},{"key":"bibr10-2309499018777887","volume-title":"Peripheral nerve injuries.
