Achilles Tendon Stiffness

Achilles tendon stiffness is a symptom of the injuries below.  The Achilles tendon is the thick, prominent band of tissue at the back of the ankle. If you have a stiff Achilles tendon then it is most likely worse first thing in the morning, or after a period of sitting or sustained rest. Factors that contribute to sore Achilles tendons include:

  • Age: Tendons tend to lose elasticity and become stiffer with age.
  • Overuse: Repetitive stress from running and jumping leads to micro-tears and inflammation.
  • Inactivity: Lack of movement also causes the tendon to stiffen.
  • Injury: Acute injuries such as a tear or rupture leads to stiffness during the healing process.
  • Medical Conditions: for example, arthritis or diabetes.

If you have Achilles tendon stiffness you most likely have limited range of motion in the ankle, pain, especially during or after exercise, tenderness and swelling.
