Introduction: Lower limb tendinopathies as patellar tendinopathy (PT) and Achilles tendinopathy (AT) are common overuse injuries in sports that are characterized by persistent pain. It is presumed that persistent pain is based on altered somatosensory profiles of the central nervous system. The aim was therefore to assess differences in mechanical pain thresholds between patients with persistent tendinopathies and controls without pain & injuries, and to assess a possible relationship between mental toughness of patients, the existence of injuries and the development of sensitization. Method: Mechanical tests of the Quantitative Sensory Testing (QST) protocol was used to assess possible sensitization. Ten patients with AT, seven patients with PT and eight controls (7 PT and 1 AT) were recruited. QST measures were assessed on the affected site (Achilles or patellar) to measure possible local sensitization and a reference site (elbow) to measure possible central sensitization. The Mental Toughness Questionnaire (MTQ-48) was used to assess possible mental toughness. Results: A significant increase in detection threshold was found for mechanical detection threshold (MDT) between all patients and controls on the reference site. Subanalyses for PT and controls showed no significant differences. However, all QST measures apart from MDT showed a decreasing trend in detection- and pain thresholds on both the affected and reference sites. Conclusion: Local as well as central sensitization might play a role in persistent overuse injuries as PT and AT. Despite the non-significant outcomes, a trend in altered sensitivity is shown for almost all QST measures in PT patients compared to their matched controls.
