Best Methods of Differential Diagnosis

A large quantity of specials tests exist and these tests are designed to differentiate musculoskeletal conditions. Recent meta-analyses have identified significant methodological weaknesses and great variability across studies of diagnostic accuracy. Further studies have shown that tests designed to identify selected musculoskeletal conditions (e.g. SLAP lesions, hip intra-articular dysfunction) perform poorly in nearly all studies and demonstrate poor diagnostic utility. Poor diagnostic utility is actually very common among most special tests with only a few demonstrating providing clinical value.  This course addresses a number of features associated with differential diagnosis. First, the course discusses the World Health Organisation (WHO) criteria required to qualify as a “diagnosis”. Second, the course discuss the necessity (or lack of necessity) for an accurate diagnosis. Third, the most common metrics are discussed to allow standardized evaluation of special tests. Fourth, the “best tests” will be discussed using the common metrics and research study quality to guide the selections. Lastly, common conditions are outlined that fail to meet the diagnostic criteria of the WHO but are encountered daily by physiotherapists.  The course will consist of demonstration, discussion and debate.

Learning Objectives:
  1. Attendees will compare and contrast the World Health Organisation criteria for diagnosis.
  2. Attendees will discuss the common metrics for differential diagnosis.
  3. Attendees will analyse the “best” tests for diagnosis of musculoskeletal disorders.
  4. Attendees will debate the reasons there is notable variability in reporting of diagnostic values across studies (in the literature).
