Patients had a mean age of 7.56 years (standard deviation, 4.28); 57% were male; and 14 had hemiplegia, 22 had diplegia, 8 had triplegia, and 54 had quadriplegia. Most SEMLCs (72%) were performed with a combination of BTX\u2010A and 5% phenol in a session. UEs were reported for 31\/146 (21%) of SEMLC sessions, with 16 of 31 UEs being temporary weakness. The overall incidence of UEs of the group that received combined agent treatment was not different from the group that received BTX\u2010A only (<jats:italic>P<\/jats:italic> = .267). Transient pain occurred in 7 of 105 patients who were treated with the combined agents BTX\u2010A and phenol. Dysesthesia did not develop in any of the patients. The type of CP, GMFCS level, number of muscles injected, and doses of medications were not correlated with the incidence of UEs.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>SEMLC using combined BTX\u2010A and phenol is a safe procedure for children with spastic CP. It could be a treatment option for patients with diffuse spasticity, because combining agents allowed more muscles to be treated without enduring or serious UEs. Patient and family education is essential to prepare them for the occurrence of common UEs, such as temporary weakness and pain.<\/jats:p><\/jats:sec>","DOI":"10.1016\/j.pmrj.2015.05.020","type":"journal-article","created":{"date-parts":[[2015,5,29]],"date-time":"2015-05-29T17:00:44Z","timestamp":1432918844000},"page":"1073-1080","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["A
