Achilles’ Tendon Injuries

The Achilles’ tendon is the largest tendon in your body and is located in the back of your ankle. It is a commonly injured tendon in the body. There can be many factors leading to injury:

– Excessive ankle pronation: All tendons like to used in a linear fashion. When there is excessive ankle pronation, this causes the Achilles’ tendon to be stressed on the one side more than the other due to poor biomechanics. Over time, this one-sided stress can lead to repetitive overuse injuries like tendinitis.

– Tight calves: Your calves are primarily formed by two large muscles (gastrocnemius and soleus) which attach to the Achilles’ tendon. If they are excessively tight, it puts undue stress (especially if you also have excessive ankle pronation) on the tendon and can also lead to injury

– Weak hips: Weak gluteal muscles can lead to poor biomechanics all the way down to your feet, affecting your Achilles’ tendon by placing undue stress on one side of your tendon, similar to excessive pronation.

– Previous ankle injury: Any previous traumatic injury (ie sprain, fracture) can lead to scar tissue buildup, loss of range of motion and stretch which can lead to altered ankle biomechanics.

– Sudden high impact activity increase: Increasing your activity too quickly can place too much stress on the Achilles’ tendon for it to properly heal after each activity session (ie. tennis, running, soccer, etc) leading to injury.

If you have any pain symptoms in your Achilles’ tendon, do not ignore them. Since Achilles’ tendon injuries are typically repetitive in nature, it could be a sign of an injury waiting to happen.

Proper biomechanics are key to treating and preventing this type of injury. Come into Form & Function and see one of our healthcare professionals to make sure your biomechanics are tip top shape!
