Objective[edit | edit source]

A patient-reported scale of shoulder dislocation/subluxation events, and pain. it is used for assessing outcomes of shoulder surgery for conditions associated with shoulder instability, including recurrent dislocation/subluxation[1].

Intended Population[edit | edit source]

The Oxford Shoulder Instability Score (OSIS) is a short, 12-item, specific, patient-reported outcome scale that was developed and validated for measuring surgical and non-surgical therapeutic outcomes of patients with shoulder instability.

The Oxford shoulder instability score (OSIS) consists of 12 questionnaire items with 5 ordinal response options each. Recall period “during the last 6 months” for 1 item; “during the last 3 months” for six items, and “during the last 4 weeks” for five items. The scoring of each item is 0–4 (4 = best/least problems).[2]

the total summation of all items on the score is 48, the lower the score the greater the disability.

Reliability[edit | edit source]

Internal consistency was established, the test had a very high test-retest reliability.[1]

Validity[edit | edit source]

the validity of the score was established by the literature[1].

Responsiveness[edit | edit source]

the score was found to be sensitive for changes that occur in response to treatment[1].
