Kim's test - posterior shoulder instability

Video source

• Rationale: Provocation through compression of the posteroinferior labrum

  
  

• Technique

  • Starting position: 90-degree abduction and 90-degree elbow flexion. The examiner applies axial force through the humerus while also applying a downward and posterior force with another hand placed distal to the deltoid tuberosity.

  • The tested shoulder is elevated diagonally while all these forces are maintained.

• Positive sign: Sudden posterior shoulder pain and a click in the shoulder.

• Validity

  • LR+ 20.83; LR- 0.26 according to Morey et al., 2016

  • Strong predictor of the condition when positive
