Your Achilles tendon is located at the back of your foot, just above your heel. It connects your heel to the two muscles of your calf and helps your foot push forward every time you take a step. If the tendon becomes swollen or irritated due to overuse, it can lead to the painful condition called Achilles tendonitis. If Achilles tendonitis goes untreated, it can become a chronic (ongoing) condition that makes just walking around almost impossible. Achilles tendonitis is a very common running injury. But it can also affect basketball players, dancers, or people who put a lot of repeated stress on their feet. It can be very painful.
Possible factors leading to the development of Achilles tendonitis include the following. Implementing a new exercise regiment such as running uphill or climbing stairs. Change in exercise routine, boosting intensity or increasing duration. Shoes worn during exercise lack support, either because the soles are worn out or poor shoe design. Omitting proper warm-up prior to strenuous exercise. Running on a hard or uneven surface. Deformation in foot such as a flat arch, or any anatomic variation that puts unnecessary strain on the Achilles tendon.
Symptoms of Achilles tendonitis include, pain in the back of the heel, difficulty walking, sometimes the pain makes walking impossible, swelling, tenderness and warmth of the Achilles tendon. Achilles tendonitis is graded according to how severe it is, mild – pain in the Achilles tendon during a particular activity (such as running) or shortly after. Moderate – the Achilles tendon may swell. In some cases, a hard lump (nodule) may form in the tendon. Severe – any type of activity that involves weight bearing causes pain of the Achilles tendon. Very occasionally, the Achilles tendon may rupture (tear). When an Achilles tendon ruptures, it is said to feel like a hard whack on the heel.
A doctor or professional therapist will confirm a diagnosis, identify and correct possible causes, apply treatment and prescribe eccentric rehabilitation exercises. An MRI or Ultrasound scan can determine the extent of the injury and indicate a precise diagnosis. Gait analysis along with a physical assessment will identify any possible biomechanical factors such as over pronation which may have contributed to the achilles tendonitis and training methods will be considered. Biomechanical problems can be corrected with the use of orthotic inserts and selection of correct footwear.
Physical therapy is the first and most useful defense for achilles tendonitis because of the two presentations outlined above. Treatments for the two types are quite different in approach. Midsubstance tendinitis responds well to stretching, whereas insertional tendnitis tends to be aggravated more by it. Depend on your trusted physical therapist to differentiate between the two and follow their guidelines on exercises and running modifications. Running gait patterns that show excessive ?sinking postures? tend to point to the source of achilles tendon problems. Altering your gait in the midstance phase of the cycle can reduce the load on the tendon dramatically and thereby reduce pain. Rely on your running physical therapist for proper guidance on altering your gait the right way. Stride Strong?s Portland Running Clinic gait analysis can identify and fix potential issues before pain sets in. Icing at the onset of acute achilles pain (i.e. when the injury is fresh and new) would help control the inflammation. Your next step should be to call our number for an appointment.
Surgery usually isn’t needed to treat Achilles tendinopathy. But in rare cases, someone might consider surgery when rubbing between the tendon and the tissue covering the tendon (tendon sheath) causes the sheath to become thick and fibrous. Surgery can be done to remove the fibrous tissue and repair any small tendon tears. This may also help prevent an Achilles tendon rupture.
Regardless of whether the Achilles injury is insertional or non-insertional, a great method for lessening stress on the Achilles tendon is flexor digitorum longus exercises. This muscle, which originates along the back of the leg and attaches to the tips of the toes, lies deep to the Achilles. It works synergistically with the soleus muscle to decelerate the forward motion of the leg before the heel leaves the ground during propulsion. This significantly lessens strain on the Achilles tendon as it decelerates elongation of the tendon. Many foot surgeons are aware of the connection between flexor digitorum longus and the Achilles tendon-surgical lengthening of the Achilles (which is done to treat certain congenital problems) almost always results in developing hammer toes as flexor digitorum longus attempts to do the job of the recently lengthened tendon. Finally, avoid having cortisone injected into either the bursa or tendon-doing so weakens the tendon as it shifts production of collagen from type one to type three. In a recent study published in the Journal of Bone Joint Surgery(9), cortisone was shown to lower the stress necessary to rupture the Achilles tendon, and was particularly dangerous when done on both sides, as it produced a systemic effect that further weakened the tendon.
