The Achilles tendon is the thickest and strongest tendon in the human body, connecting the calf muscles to the heel bone. Despite its strength, it is highly vulnerable to injury in runners, footballers, and badminton players due to the massive forces absorbed during sprint push-offs.
When the tendon becomes overloaded, it develops micro-tears and inflammation, a condition known as **Achilles Tendinitis** (or more accurately, **Achilles Tendinopathy**). If left untreated, chronic tendon degeneration can lead to a sudden, painful Achilles tendon rupture.
At **Physio Dynamics** in Panamaram, Wayanad, chief sports physiotherapist **Dr. Sandra Thomas (PT)** utilizes evidence-based loading protocols (such as the Alfredson Eccentric Heel Drop Program) to guide tendon regeneration and restore heel durability.
Mid-Portion vs. Insertional: Mid-portion tendinitis (pain 2-6 cm above the heel) responds well to eccentric heel drops off a step. Insertional tendinitis (pain at the very bottom of the heel) requires heel drops onto flat ground to avoid bone compression.
Symptoms of Achilles Tendinitis
Common signs of Achilles tendon overload include:
- Morning Stiffness: A tight, aching heel tendon when you take your first steps in the morning.
- Pain Under Load: Sharp pain during jumping, running, or pushing off on your toes.
- Tendon Thickening: The tendon feels swollen or develops a noticeable nodule.
- Tenderness to Touch: Sharp pain when you squeeze the sides of the tendon.
The Alfredson Eccentric Heel Drop Protocol
Modern sports medicine has proven that tendons require controlled load to heal. The **Alfredson Protocol** is the gold standard exercise program for mid-portion Achilles tendinitis:
Straight-Knee Eccentric Heel Drops
Stand with the balls of both feet on the edge of a step. Lift up onto your toes using both legs. Lift your healthy leg off the step, and slowly lower your body down using only the injured leg until your heel is below the step (taking 3-5 seconds). Place your healthy leg back on the step to push back up. Complete 3 sets of 15 repetitions. This targets the Gastrocnemius muscle.
Bent-Knee Eccentric Heel Drops
Perform the exact same heel drop sequence, but keep the knee of your injured leg slightly bent (about 30 degrees) during the lowering phase. Complete 3 sets of 15 repetitions. This isolates the Soleus calf muscle, which absorbs major impact force during running.
Alfredson Schedule: Perform these exercises twice daily, 7 days a week, for 12 weeks. Mild discomfort during the exercise is normal, but sharp, lingering pain is a sign to reduce load.
