Background:
Achilles tendinopathy is a common overuse-related musculoskeletal disorder. The relationships among patient-reported outcome measures (PROMs), functional performance, and structural tendon changes remain poorly understood. This study aimed to clarify the relationships among these measures in patients with Achilles tendinopathy.
Methods:
46 patients with mid-portion Achilles tendinopathy were included in the study. Evaluations included PROMs, functional performances, and tendon properties. Pearson correlation analysis and multiple linear regression were used to explore the relationships between measures.
Results:
Only Victorian Institute of Sport Assessment-Achilles was found to have a significant association with Achilles tendon thickness (p = 0.038, β = 0.368), and tendon stiffness was found to have a significant association with maximal voluntary isometric contractions of ankle plantarflexion (p < 0.001, β = 0.598).
Conclusion:
The relationships among PROMs, tendon properties, and functional performances are weak. Combining these outcomes is suggested for a comprehensive evaluation of patients with Achilles tendinopathy.
Levels Of Evidence:
