Insertional Achilles tendinopathy is a disabling injury that is common in running athletes.
 Exercise therapy is considered the best treatment option, but there is still no agreement on
 the modalities. For example, it is thought that compression overload may be a major cause of
 tendinopathy and should therefore be restricted during rehabilitation. However, this
 recommendation is based on expert opinion and not on hard scientific evidence. Therefore,
 this randomised controlled trial (RCT) will investigate whether a therapy that limits the
 amount of compression of the tendon during a progressive tendon-loading rehabilitation
 protocol actually has better outcomes in athletes with insertional Achilles tendinopathy.
 
 40 athletes with insertional Achilles tendinopathy will be randomised into two treatment
 groups; (1) an experimental 12-week rehabilitation protocol in which the amount of tendon
 compression is limited and (2) a 12-week control rehabilitation protocol in which the amount
 of tendon compression is not limited and is rather high. Both treatments consist of
 supervised progressive tendon-loading exercise therapy and patient education. In addition,
 the experimental group will also receive heel inserts to limit the amount of dorsiflexion
 during sports or daily activities. At baseline, at 12 weeks (end of intervention) and at 24
 weeks (follow-up), pain, functionality, structure and intratendinous pressure will be
 determined.
