Although orthotic and exercise therapies are commonly offered by physicians for PC treatment, there is a lack of evidence on the benefits of exercises and how long the orthosis should be worn. The aim of this study is to investigate the effects and feasibility of custom-made compression orthosis and exercises in the treatment of PC.<\/jats:p><jats:p>\n          Materials and Methods\u2003Patients with PC aged 7 to 17 years old were randomized into three groups: compression orthosis 23\u2009hours, compression orthosis 8\u2009hours, and control group. All groups received exercises for 1\u2009hour a day for 3 weeks. Additionally, compression orthosis 23\u2009hours group wore the orthosis for 23\u2009hours a day, while compression orthosis 8\u2009hours group wore the orthosis for 8\u2009hours a day. PC protrusion, pressure of correction, thorax lateral and anteroposterior parameters, external chest wall measurements, and Nuss Questionnaire were evaluated before and after the treatment. Also, adverse effects, retention, and compliance were assessed. Feasibility was evaluated by calculating the percentages of recruitment, retention, and safety.<\/jats:p><jats:p>\n          Results\u2003The compression orthosis 23\u2009hours group showed greater improvements than the other groups. After treatment, all groups showed significant changes in protrusion, pressure of correction, and external chest wall measurements. Adverse events occurred with similar frequency across groups. Retention percentages did not differ among groups.<\/jats:p><jats:p>\n          Conclusion\u2003Compression orthosis use for 23\u2009hours can be recommended rather than its use for 8\u2009hours because 23\u2009hours of orthosis use has better correction and similar adverse effects.<\/jats:p>","DOI":"10.1055\/s-0040-1701699","type":"journal-article","created":{"date-parts":[[2020,3,8]],"date-time":"2020-03-08T23:30:51Z","timestamp":1583710251000},"page":"147-156","source":"Crossref","is-referenced-by-count":8,"title":["A Comparative Study on Short-Term Effects of Compression Orthosis and Exercises in the Treatment of Pectus Carinatum: A Randomized Controlled Pilot Feasibility Trial"],"prefix":"10.1055","volume":"31","author":[{"given":"Esra","family":"Giray","sequence":"additional","affiliation":[{"name":"Department of Physical Medicine and Rehabilitation, Marmara University School of Medicine, Istanbul, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nezih Onur","family":"Ermerak","sequence":"additional","affiliation":[{"name":"Department of Thoracic Surgery, Marmara University School of Medicine, Istanbul, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yeliz","family":"Bahar-Ozdemir","sequence":"additional","affiliation":[{"name":"Department of Physical Medicine and Rehabilitation, Marmara University School of Medicine, Istanbul, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Melihat","family":"Kalkandelen","sequence":"additional","affiliation":[{"name":"Department of Physical Medicine and Rehabilitation, Marmara University School of Medicine, Istanbul, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mustafa","family":"Yuksel","sequence":"additional","affiliation":[{"name":"Department of Thoracic Surgery, Marmara University School of Medicine, Istanbul, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Osman Hakan","family":"Gunduz","sequence":"additional","affiliation":[{"name":"Department of Physical Medicine and Rehabilitation, Marmara University School of Medicine, Istanbul, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gulseren","family":"Akyuz","sequence":"additional","affiliation":[{"name":"Department of Physical Medicine and Rehabilitation, Marmara University School of Medicine, Istanbul, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2020,3,8]]},"reference":[{"issue":"01","key":"ref1","doi-asserted-by":"crossref","first-page":"40","DOI":"10.1016\/j.jpedsurg.2005.10.076","article-title":"Nonoperative management of pectus carinatum","volume":"41","author":"A S Frey","year":"2006","journal-title":"J Pediatr Surg"},{"issue":"10","key":"ref2","doi-asserted-by":"crossref","first-page":"1583","DOI":"10.1016\/j.jpedsurg.2017.04.011","article-title":"Does an external chest wall measurement correlate with a CT-based measurement in patients with chest wall deformities?","volume":"52","author":"F Ewert","year":"2017","journal-title":"J Pediatr Surg"},{"issue":"01","key":"ref3","doi-asserted-by":"crossref","first-page":"44","DOI":"10.1053\/j.semtcvs.2009.03.001","article-title":"Anatomical, histologic, and genetic characteristics of congenital chest wall deformities","volume":"21","author":"A A Fokin","year":"2009","journal-title":"Semin.
