is Achilles Tendonitis?
tendonitis is a common disorder of the lower leg. Achilles tendonitis
is an overuse type injury, which causes irritation to the tendon.
Researchers have documented that 11% of all running injuries can
be attributed to Achilles tendonitis.
Achilles tendon is the common tendon of the soleus and gastrocnemius
muscles. Its primary function is to point your foot downward (plantarflexion)
or raise your heel. The Achilles tendon plays a functional role
in push-off during your gait cycle, jogging and running.
are two types of Achilles tendonitis; one is insertional and the
other is non-insertional. Insertional Achilles tendonitis
is distinguished by a localization of the patients symptoms
to the insertion point of the tendon into the calcaneus. The signs
and symptoms are pain during or after exercise and an erythema to
tendonitis is classified by pain 2-6 cm. above the Achilles
tendon insertion. Signs and symptoms include pain after exercise,
pain and stiffness is present in the early morning (first steps
out of bed). If symptoms persist, pain may become constant. There
is also a thickening of the tendon and surrounding swelling.
tendonitis can further be broken down into two subsets: Paratenonitis
Paratenonitis is when there is a pathologic change to the matrix
of the tendon.
Tendinosis is classified as a damaged paratenonitis; the tendon
has now become degenerated. You now have chronic pain, which has
been present for at least sixteen weeks.

Phase I First 24 to 72 Hours
etiological factors; biomechanical connection (Heel lift orthotics)
II 3 Days to 3-4 Weeks
Gentle, passive stretching (Both soleus and gastrocnemius muscles).
I.e. Bent and straight leg
III 4 Weeks to Return to Activity
Progress with strengthening program
to running program
return to full activity
