- Impairments in maximal plantarflexor torque and concentric plantarflexor endurance were observed on the affected side versus unaffected side.
BACKGROUND & OBJECTIVE
There is a paucity of research on the presence of plantarflexor muscle impairments in individuals with Achilles tendinopathy (AT) when compared to the unaffected side and to healthy controls. The influence of progressive resistance training on plantarflexor muscle function in this population is also unclear.
The primary aim of this paper was to investigate the presence of plantarflexor muscle impairments with AT in two ways, i.e. AT versus healthy controls, and affected leg versus unaffected leg. The secondary aim was to assess the change in various parameters of plantarflexor muscle function over time among individuals with AT undergoing resistance training.
Improvement in plantarflexor muscle function is not necessary for symptomatic improvement in those with Achilles tendinopathy.
PRISMA guidelines were followed for the reporting of this systematic review. Included studies compared muscle function between affected versus unaffected side, AT versus healthy controls, and assessed change in function over time. Measures of plantarflexor function included strength, power, explosive
