Achilles tendon length, Achilles tendon moment arm, Achilles tendon thickness, foot lever ratio

The aim of this study was to compare the dimensions of Achilles tendon, Achilles tendon moment arm and foot lever ratio between runners with tendinopathy and healthy control runners. We paired 12 runners diagnosed with baseline tendinopathy with 12 healthy control runners. The dimensions of Achilles tendon, Achilles tendon moment arm and foot lever ratio were measured using kinematic analysis and ultrasound imaging. Based on the parametric paired-samples T-Test, we compared the dependent variables measured on the affected lower limb. No differences were found between the groups for Achilles tendon length, Achilles tendon moment arm and foot lever ratio. Runners diagnosed with tendinopathy had thicker Achilles tendons than healthy control runners.
