This is a protocol for a Cochrane Review (Intervention). The objectives are as follows:

To assess the effects (benefits and harms) of exercise, orthoses and splinting for treating Achilles tendinopathy.

We will compare each of the three intervention categories (exercise, orthoses, splinting) with no intervention, a placebo intervention or advice to rest; and with each other. We will also compare different types, applications and modes of delivery of interventions within the three intervention categories.
