This is the second app that we have reviewed in the Clinical Pattern Recognition app series developed by Michael Wong, with the focus of this app being low back pain.

Clinical Scenario

36 year old female presents complaining of low back pain after she felt she pulled something while she was doing a workout a few weeks ago. She felt some tingling in her right thigh, that resolved but the dull, achy back pain has persisted and hasn’t really improved.

User interface

The app opens momentarily to a title screen and then to the home page.



Tapping on clinical pattern recognition brings up 2 ways of looking up conditions; viewing all of them as a list or tapping on a corresponding pain pattern to view a differential.



In this case she is having midline bilateral low back pain so I tapped on the corresponding pain pattern to view a differential. Based on her symptoms, lumbar muscle strain is most likely at this time.


When a diagnosis is selected, you are presented with options to view prevalence, clinical findings, physical exam, interventions and outcome measures.


Each section has videos and accompanying text on how to perform examination maneuvers, how to position yourself and the patients, as well as expected findings.






On the home page, tapping on the menu button brings up information on other apps in the series and tapping about brings up information about the clinicians and developers of the app.



Evidence and literature used to support the app
Almost every section of the app has references clearly mentioned at the bottom of the screen with links to the corresponding article or Pubmed page.
