Achilles tendinopathy physical therapy

Understand the tendon under load

The Achilles tendon connects the calf muscles to the heel and transfers force during walking, running, and jumping. Tendinopathy describes tendon pain and reduced function associated with loading. It is not the same as an acute rupture, where the tendon tears.

Symptoms may involve the middle of the tendon or its attachment to the heel, called insertional tendinopathy. That distinction matters because an exercise range tolerated by one person may aggravate another person’s heel attachment.

Pain patterns and other possibilities

Common complaints include morning stiffness, pain behind the heel or along the tendon, and discomfort with push-off, hills, or jumping. The tendon may feel tender or thickened. Symptoms sometimes ease during a warm-up and return afterward; warming up does not establish readiness for harder training.

A calf injury, irritated heel bursa, or bone stress injury can also cause nearby pain. An examination is needed to distinguish these possibilities rather than diagnosing tendinopathy from location alone.

Assess before adding more load

Assessment may review changes in mileage, speed work, hills, footwear, daily walking, health history, and medications. A therapist can examine the location of tenderness, ankle motion, calf strength, and walking mechanics. Heel-raise testing is introduced only when appropriate for the suspected injury.

A sudden injury or major loss of push-off strength requires screening for rupture before routine loading exercises. Imaging is not always necessary, but may help when the diagnosis is uncertain or another injury is suspected.

Build calf strength with the right range

A possible rehab plan combines changes to aggravating activity with progressive calf strengthening. Heel raises may begin with support or reduced load and become more demanding as tolerated. Exercise resistance, range, and frequency should be individualized rather than copied from a generic challenge.

Insertional symptoms need particular care with deep ankle bending. Aggressive calf stretching or heel drops below a step can aggravate the attachment. A clinician may select a smaller range or temporary heel lift while building capacity.

Prepare for speed and spring

Running and jumping ask the tendon to handle repeated, rapid loading, not just a slow heel raise. Return planning may consider calf strength, repeated heel-raise performance, walking tolerance, and later hopping or sport-specific tasks when appropriate.

Progress running volume, speed, and hills separately rather than using one comfortable session as clearance. Track both the exercise response and the next morning’s stiffness. Worsening pain, reduced push-off, or a persistent decline in function warrants reassessment.

When calf or heel pain needs urgent help

A sudden pop, a sensation of being kicked in the calf, or abrupt loss of push-off strength needs urgent same-day medical assessment for possible rupture. Do not test it with repeated hopping or forceful stretching, even if you can still walk.

New, unexplained one-sided calf swelling, warmth, or redness also needs urgent assessment because a blood clot is one possible cause. Call 911 if accompanied by chest pain or breathlessness. Persistent tendon symptoms deserve review even without these warning signs.
