Background : Tennis elbow is a syndrome that commonly diagnosed in patient who comes with lateral elbow pain. Instability
pain in tennis elbow patient was observed and reported in many previous literatures. Posterolateral rotatory apprehension
test was proposed for diagnosis of posterolateral rotatory instability of elbow. However, no review literatures that studied
about posterolateral rotatory apprehensions test in tennis elbow.
Objective : To find out the relationship between posterolateral rotatory apprehension test and tennis elbow.
Material and Method: There were 44 patients that were recruited in this study. We examined the posterolateral rotatory
apprehension test in tennis elbow patients. The examination was done in our outpatient clinic from March 2012 to April 2012.
The data was collected to find out the ratio of negative test in tennis elbow patient.
Results : The results from the posterolateral rotatory apprehension test were negative in 43 patients. The ratio of the negative
test result was 98%.
Conclusion : A result from posterolateral rotatory apprehension test should be negative in general tennis elbow patients. If
this test is used in a tennis elbow patients who are suspected with hidden instability and the result is positive, further evaluation
is strongly suggested.
