The patients were divided into 2 groups with respect to the presence of pain in the jerk test: the painless jerk group (54 shoulders) and the painful jerk group (35 shoulders). Response to the nonoperative treatment was evaluated after at least a 6-month rehabilitation program. Patients who did not respond to the rehabilitation underwent arthroscopic examination to identify any pathologic lesions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The painful jerk group had a higher failure rate with nonoperative treatment (P&lt; .001). In the painless jerk group, 50 shoulders (93%) responded to the rehabilitation program after a mean of 4 months. Four shoulders (7%) were unresponsive to the rehabilitation. In the painful jerk group, 5 shoulders (16%) were successful with the rehabilitation, whereas the other 30 shoulders (84%) failed. All 34 shoulders that were unresponsive to the rehabilitation had a variable degree of posteroinferior labral lesions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The jerk test is a hallmark for predicting the prognosis of nonoperative treatment for posteroinferior instability.
