Biceps tendon and Rx?

[sports therapy]

Hi i am a 3rd year sports therapy student and i have a 20 year old male that does recreational kayaking. He is complaining of a twinging pain around the corocoid process and a sharp pain down the medial aspect of his arm following a role in a kayak.

I have carried out an assessment and have come to the conclusion he has a tear in the short head of the biceps tendon; during the ludingtons test palpation was painful and the tendon was more apparent on the injured side.

The patient is fairly slender and does not have much muscle bulk around the upper body; i am wanting to do strengthening exercises but am unsure of what to do as i do not want to irritate.
I am considering also frictions to reduce pain- could anyone advice me?

Thanks

I would do the special test Yergasons to check long head of bicep involvement, you could also check the integrity of the transverse humeral ligament with ER with palpation to see if the tendon rolls out.
If these are clear then likely it is the supra as suggested above.
After the acute phase, treated with positioning and modalities, I dive into eccentrics. Research has shown them to be effective with tendonopathies.
