Achilles tendinopathy is a painful and disabling tendon injury that can persist for months to years. It may occur when a tendon is exposed to high magnitude loading that is repetitive in nature.
Tendinopathy presents with structural changes including thickening of the tendon, altered cell tissue and organisation, disorganised collagen alignment (normally running parallel), formation of new blood vessels and nerve ingrowth in within the tendon. tendon pain that is experienced is partly attributed to the changes in blood vessels and nerve ingrowth in the tendon.
Often a painful achilles tendon results in a reduced ability to produce tendon stiffness with activity and sports involving running and jumping. Increased tendon stiffness is actually more mechanically efficient as it allows for more recoil and elastic energy to be produced (think of a thick/stiff vs thin/compliant elastic band).
The presence of pain and symptoms may also lead to changes in mechanics and loading strategies throughout the entire lower limb. Recurrence is common, especially if rehabilitation does not meet the requirements of the individuals’ goals and sporting demands.
If you need help with your niggly pains, DM me for a consult and a tailored exercise program.
