28
Q

Initial goals of early rehab in tendinopathies

A

Decrease pain
Guide inflammation
Fix the cause of the problem

29
Q

When will patient typically come and seek treatment?

A

When the pain affects their performance

30
Q

Which type of strengthening can begin early in rehab?

Eccentrics

31
Q

Tendons have ___ vascular supply compared to muscle and ligaments

A

Poor

32
Q

Which part of the tendon has a better vascular supply?

A

Paratendon (tendon sheath surrounding tendon)

33
Q
