Following that up with your objective ROM, and muscle testing, will further confirm your analysis. Active resisted testing of the suspect structure is extremely helpful. Tendinitis usually has a pain response that is constant on active resisted exercises such as “speed tests”, and while bursitis also reports pain on active resisted, the pain increases with contraction as the structure continues to contract over the bursa. It’s necessary to be clear that the pain is where the bursa is located, not in the joint or referral. It’s also relevant to use a pain scale to chart the pain increasing with contraction.
