Achilles tendon enthesopathy is pain where the Achilles tendon attaches to the back of the heel bone.
- People typically feel pain at the back of the heel when walking.
- Diagnosis includes an examination of the tendon.
- Stretching, night splints, and heel lifts may help.
(See also Overview of Foot Problems.)
The cause is chronic traction (pulling) of the Achilles tendon where it attaches to the heel bone. Contracted or shortened calf muscles caused by being sedentary and overweight or caused by athletic overuse increase the risk. Occasionally, people with Achilles tendon enthesopathy have arthritis elsewhere (spondyloarthritis).
To minimize stress to the Achilles tendon when walking, the foot and ankle should be moved actively through the ranges of motion for about a minute when rising after long periods of rest.
Night splints may also be used to stretch the tendon during sleep and help prevent the calf muscles from becoming too tight.
Heel lifts are used temporarily for both feet to relieve pain, decrease stress on the tendon, and correct abnormal motion of the hip or back while walking.
Doctors may consider extracorporeal pulse activation therapy (EPAT) for people whose enthesopathy is difficult to heal. In this therapy, doctors use a device to apply pressure waves of sound to the heel. The pressure waves stimulate blood circulation, which may help healing.
