An Achilles tendon injury (tendinopathy) is one of the most common causes of pain felt behind the heel and up the back of the ankle when walking or running. While Achilles tendinopathy affects both active and inactive individuals, it is most common in active individuals; 24% of athletes develop the condition. Males experience 89% of all Achilles tendon injuries, and an estimated 50% of runners will experience Achilles pain in their running careers. In all individuals, Achilles tendinopathy can result in a limited ability to walk, climb stairs, or participate in recreational activities.
What Is Achilles Tendinopathy?Achilles tendinopathy is often the result of several microtears, or tiny tears in and around the tendon tissue. This aspect of the condition is referred to as tendinosis. In the past, the condition was commonly referred to as Achilles tendinitis, which means inflammation of the tendon. However, research has shown that inflammation is rarely the cause of the condition.
Achilles Tendon Injuries
Achilles tendinopathy is an irritation of the Achilles tendon, a thick band of tissue along the back of the lower leg that connects the calf muscles to the heel. The term tendinopathy refers to any problem with a tendon, either short or long term. The Achilles tendon helps to balance forces in the leg and assists with movement of the leg and the ankle joint. Achilles tendinopathy results when the demand placed on the Achilles tendon is greater than its ability to function. This can occur after 1 episode (acute injury) or after repetitive irritation or “microtrauma” (chronic injury).
The severity of acute injuries is graded based on the amount of damage to the tendon:
Grade I: Mild strain, disruption of a few fibers. Mild to moderate pain, tenderness, swelling, stiffness. Expected to heal normally with conservative management.
Grade II: Moderate strain, disruption of several fibers. Moderate pain, swelling, difficulty walking normally. Expected to heal normally with conservative management.
Grade III: Complete rupture, often characterized by a “pop,” immediate pain, inability to bear weight. Typically requires surgery to repair.
Most often, Achilles tendon pain is the result of repetitive trauma to the tendon. This repetitive strain can result in chronic Achilles tendinopathy, which is a gradual breakdown of the tissue and is most often treated with physical therapy.
Symptoms and common causes of Achilles tendinopathy may include:
Abnormal foot structure
Abnormal foot mechanics
A change in an exercise routine or sport activity
Pain can be present at any point along the tendon; the most common area to feel tenderness is just above the heel, although it may also be present where the tendon meets the heel.
Achilles Tendinopathy Patients
The following may be risk factors for Achilles tendinopathy:
Poor calf muscle endurance
Higher than average body weight
Weak or tight calf muscles
Stiff foot joints
Poor hip and knee core stability
What does Achilles pain feel like?
With Achilles tendinopathy, you may experience:
Tenderness in the heel or higher up in the Achilles tendon
Tightness in the ankle
Tightness in the calf
Swelling in the back of the ankle
Pain in the back of the heel
Pain and stiffness with walking, worst with the first several steps
How is Achilles pain diagnosed?
Your physical therapist will review your medical history and complete a thorough examination of your heel. The goals of the initial examination are to assess the degree of the injury and determine the cause and contributing factors to your injury. It is common for your physical therapist to perform a movement assessment. This may include watching you walk, squat, step onto a stair, or balance on 1 leg. The motion and strength in your leg will also be assessed. Your physical therapist may also ask questions regarding your daily activities, exercise regimens, and footwear to identify other contributing factors. Imaging techniques, such as x-ray or MRI, are often not needed to diagnose Achilles tendinopathy.
Achilles Tendinopathy Treatment
How Can a Physical Therapist treat Achilles pain?
You and your physical therapist will work together to develop a plan to help you achieve your specific goals. To do so, your physical therapist will select treatment strategies including any or all of the following areas:
Pain. Many pain-relief strategies may be implemented, such as applying ice to the area, putting the affected leg in a brace, or using therapies such as iontophoresis (a medicated patch placed on the skin that is electrically charged and used to decrease pain and inflammation) or therapeutic ultrasound.
Range of motion. Your ankle, foot, or knee joint may be moving improperly, causing increased strain on the Achilles tendon. Self-stretching and manual therapy techniques (massage and movement) applied to the lower body to help restore and normalize motion in the foot, ankle, knee, and hip can decrease this tension.
Muscular strength. Muscular weaknesses or imbalances can result in excessive strain on the Achilles tendon. Based on your specific condition, your physical therapist will design an individualized, progressive, lower-extremity resistance program for you. You may begin by performing strengthening exercises in a seated position — for example, pushing and pulling on a resistive band with your foot. You then may advance to exercises in a standing position — for example, standing heel raises.
Manual therapy. Your therapist may treat your condition by applying hands-on treatments to move your muscles and joints in order to improve their motion and strength. These techniques often address areas that are difficult to treat on your own.
Functional training. Once your pain, strength, and motion improve, you will need to safely transition back into more demanding activities. To minimize the tension on the Achilles tendon and your risk of repeated injury, it is important to teach your body safe, controlled movements. Based on your goals and movement assessment, your physical therapist will create a series of activities that will help you learn how to use and move your body correctly to safely perform the tasks required to achieve your goals.
Patient education. Your therapist will work with you to identify, and establish plans to address, any possible external factors causing your pain, such as faulty footwear or inappropriate exercises. He or she will assess your footwear and recommend improvements, and develop a personal exercise program to help ensure a pain-free return to your desired activities.
Physical therapy promotes recovery from Achilles tendon injuries by addressing issues such as pain or swelling of the affected area, and any lack of strength, flexibility, or body control. When the condition remains untreated, pain will persist and may result in a complete tear of the Achilles tendon, which often requires surgery to repair. Physical therapy shows a high success when treating Achilles Tendinopathy and a 100% full recovery can be expected.
If your surgeon decides that surgery is needed, physical therapy will be necessary after surgery for several months. Immediately after surgery, your ankle will be placed in a splint or cast with crutches to allow the repaired tissue to heal. Once sufficient healing has occurred, you will work with your physical therapist to progressively regain your ankle mobility and leg strength. He or she will also help you regain your ability to walk without assistance—and carefully guide your return over time to your desired recreational activities.
Can Achilles pain be prevented?
Maintaining appropriate lower extremity mobility and muscular strength, and paying particular attention to your exercise routine—especially changes in an exercise surface, the volume of exercises performed, or your footwear are the best methods for preventing Achilles injuries.
Your physical therapist will help guide you through a process that will progressively reintegrate more demanding activities into your routine without overstraining your Achilles tendon. Keep in mind that returning to activities too soon after injury often leads to persistent pain, and the condition becomes more difficult to fix.
