Our objective was to develop an advanced, novel shoulder joint simulator and compare outcomes at two separate institutions, for a typical shoulder joint motion simulation. Identical shoulder simulators were developed &amp; deployed at both institutions. Eight cadaveric upper extremities were tested by simulating actively controlled, arm elevation in the plane of the scapula for two sequential test conditions (intact and nondestructive simulated cuff-tear), each repeated for a total of five trials. Muscle forces and joint translations were recorded for both conditions. The intact condition was repeated following simulated cuff-tear to assess effect of testing order. Statistical analyses were aimed at assessing repeatability and reproducibility of results within specimens, between specimens, and between institutions. The highest average forces were observed for the middle deltoid (233N or 32.5% body weight (BW)), followed by infraspinatus (99.0N), and posterior deltoid (93.7N) muscles. Differentiation between test conditions was unhindered by variability between repeated trials. Data from testing repeated over time, and between the two institutions were not significantly different. The novel shoulder simulator produced repeatable results with low trial-to-trial variation and outcomes were comparable between the two institutions. The results demonstrated a consistent response in muscle forces and humeral translation for the simulated rotator cuff tear condition. Such advanced shoulder simulators could thus be used for evaluating and optimizing surgical interventions and implant strategies.<\/jats:p>","DOI":"10.1115\/1.4053362","type":"journal-article","created":{"date-parts":[[2021,12,24]],"date-time":"2021-12-24T10:27:54Z","timestamp":1640341674000},"update-policy":"https:\/\/doi.org\/10.1115\/crossmarkpolicy-asme","source":"Crossref","is-referenced-by-count":4,"title":["Development and Multisite Assessment of a Novel Shoulder Motion Joint Simulator"],"prefix":"10.1115","volume":"144","author":[{"given":"Aniruddh N.","family":"Nayak","sequence":"first","affiliation":[{"name":"Biomechanics Research, Musculoskeletal-Orthopedic Research and Education (MORE) Foundation, Phoenix, AZ 85023"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stefan M.","family":"Gabriel","sequence":"additional","affiliation":[{"name":"Sports Medicine, DePuy Synthes Mitek Sports Medicine, Raynham, MA 02767"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David B.","family":"Spenciner","sequence":"additional","affiliation":[{"name":"Sports Medicine, DePuy Synthes Mitek Sports Medicine, Raynham, MA 02767; Department of Biomedical Engineering, Rensselaer Polytechnic Institute, Troy, NY 12180"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Courtney E.","family":"Mason","sequence":"additional","affiliation":[{"name":"Biomechanics Research, Musculoskeletal-Orthopedic Research and Education (MORE) Foundation, Phoenix, AZ 85023"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marc C.","family":"Jacofsky","sequence":"additional","affiliation":[{"name":"Biomechanics Research, Musculoskeletal-Orthopedic Research and Education (MORE) Foundation, Phoenix, AZ 85023; The CORE Institute, Phoenix, AZ 85023"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"33","published-online":{"date-parts":[[2022,2,18]]},"reference":[{"issue":"7","key":"2022021809052683700_bib1","doi-asserted-by":"crossref","first-page":"710","DOI":"10.1016\/j.arthro.2007.01.027","article-title":"Initial Fixation Strength of Massive Rotator Cuff Tears: In Vitro Comparison of Single-Row Suture Anchor and Transosseous Tunnel Constructs","volume":"23","year":"2007","journal-title":"Arthrosc. \u2013 J.
