Shoulder position sense was examined with 3 different protocols (passive motion to remembered shoulder rotation angles and active shoulder abduction and rotation to verbally specified positions) in positions of both mid-range and end-range of motion.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>Participants with unstable shoulders exhibited significantly larger errors (by 1.8\u00b0 on average) in perception of shoulder position compared with those with healthy shoulders during passive matching. During active positioning, participants with unstable shoulders were able to voluntarily move the shoulder to verbally specified angles as accurately as those with healthy shoulders in both abduction (0.85\u00b0 difference) and rotation (0.99\u00b0 difference) tasks.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>Results of this study indicate that people with unstable shoulders can perceive shoulder angles as accurately as people with healthy shoulders in activities with voluntary arm movements. Compared with passive matching, better information from muscle spindles and other sources during voluntary arm movements may compensate for the potential joint position sense deficits after the injury. Therefore, individuals with an unstable shoulder may have adequate neuromuscular control to engage proper protective mechanisms to stabilize the shoulder joint during functional activities.<\/jats:p>\n               <\/jats:sec>","DOI":"10.2522\/ptj.20110236","type":"journal-article","created":{"date-parts":[[2012,1,7]],"date-time":"2012-01-07T00:06:42Z","timestamp":1325894802000},"page":"563-573","source":"Crossref","is-referenced-by-count":40,"title":["Shoulder Position Sense During Passive Matching and Active Positioning Tasks in Individuals With Anterior Shoulder Instability"],"prefix":"10.1093","volume":"92","author":[{"given":"You-jou","family":"Hung","sequence":"first","affiliation":[{"name":"Y.
