Achilles Tendinopathy and Mend Physical Therapy Solutions


Achilles Tendon Problems

Achilles tendinopathy commonly occurs in runners and jumpers, with up to 50% experiencing the condition in their lifetime(1).

Not all those affected are active with 33% of individuals reporting a sedentary lifestyle(2).

Individuals with this condition report pain, stiffness, and loss of function with daily and recreational activities.

This condition was originally thought to involve inflammation but more recent evidence suggests the presence of a degenerative tendinopathy(3,4). Remodeling (healing) of the achilles tendon has been found with appropriate loading through exercise, in particular eccentric contractions(5,6). 

Achilles Tendinopathy Solutions

A Physical Therapy examination is able to determine the source of the symptoms as well as precipitating factors which caused the Achilles to be overloaded.
Physical Therapy interventions including manual therapy (spinal and extremity joint manipulation/mobilizations, soft tissue interventions including dry needling, education, and exercise are indicated in this condition.
Interventions are designed to reduce load on the tendon to allow for adaption and healing before slowly progressing the load on the tendon in preparation for return to activity. 
Alfredson et al. initially described the positive effects of eccentric loading on pain and disability among recreational athletes. All athletes were able to return to pre injury levels after a 12 week program of strengthening (7).


Systematic Reviews of the medical evidence report strong evidence for the eccentric loading program developed by Alfredson et al. but additional studies demonstrate success with other loading programs(8,10).

These programs have documented positive histological changes in the tendon consistent with remodeling and healing including increased stiffness, decreased thickness, and increased Type I collagen formation (5,6,8). These changes suggest the tendon is plastic and is able to adapt and improve with loading through exercise. 

Physical Therapy was also superior to a corticosteroid injection for the treatment of Achilles Tendinopathy.  Authors noted a 43% recurrence rate in the steroid group compared to a 16% recurrence rate in the PT group at long term follow up (12).

Referral to Physical Therapy

Research suggests pain on palpation of the achilles tendon, location of pain 2-6 cm above heel, and pain during heel raise testing are useful clinically in the diagnosis of achilles tendinopathy(11).

Patient's with ankle and  heel pain limiting daily and recreational activities should seek out Physical Therapy for the implementation of a manual therapy and eccentric exercise program.
