In Vivo Comparison of Tendon Mechanical Properties in Patellofemoral Pain
Introduction: Patellofemoral pain (PFP) is one of the most common abnormalities involving the knee, with reported incidence rates greater than 25% among athletes. Current literature suggests the etiology of PFP is multifactorial, although it is commonly accepted that abnormal patellar tracking is closely related to PFP syndrome. Abnormal patellar tracking may be due to imbalances in the extenso...
متن کاملMechanical properties of the human Achilles tendon, in vivo.
BACKGROUND Ultrasonography has been widely applied for in vivo measurements of tendon mechanical properties. Assessments of human Achilles tendon mechanical properties have received great interest. Achilles tendon injuries predominantly occur in the tendon region between the Achilles-soleus myotendinous junction and Achilles-calcaneus osteotendinous junction i.e. in the free Achilles tendon. Ho...
متن کاملTensile properties of the in vivo human gastrocnemius tendon.
In the present experiment we obtained the tensile properties of the human gastrocnemius tendon, a high-stressed tendon suitable for spring-like action during locomotion. Measurements were taken in vivo in six men. The gastrocnemius tendon elongation during tendon loading-unloading induced by muscle contraction-relaxation was measured using real-time ultrasonography. Tendon forces were calculate...
متن کاملpassivity in waiting for godot and endgame: a psychoanalytic reading
this study intends to investigate samuel beckett’s waiting for godot and endgame under the lacanian psychoanalysis. it begins by explaining the most important concepts of lacanian psychoanalysis. the beckettian characters are studied regarding their state of unconscious, and not the state of consciousness as is common in most beckett studies. according to lacan, language plays the sole role in ...
Viscoelastic properties of the Achilles tendon in vivo
It has been postulated that human tendons are viscoelastic and their mechanical properties time-dependent. Although Achilles tendon (AT) mechanics are widely reported, there is no consensus about AT viscoelastic properties such as loading rate dependency or hysteresis, in vivo. AT force-elongation characteristics were determined from 14 subjects in an ankle dynamometer at different loading rate...
