Takeaways
Tensile strain alone cannot fully explain insertional tendinopathy development.
Increased tensile loads lead to higher pressure in tendon insertions.
Torsion in tendons can significantly impact internal pressure during loading.
Intra-tendinous pressure increases with exercise, affecting tendon perfusion.
Corticosteroids can reduce GAG synthesis, impacting tendon health.
Fluid retention in tendons can lead to increased pressure and pain.
GAG accumulation in tendons is linked to swelling and pressure changes.
Rest and proper recovery are crucial for tendon health post-exercise.
High pressures in tendons can collapse blood vessels, affecting perfusion.
Exercise can help reduce fluid retention in tendons. Heavier loading creates a stronger driving force for fluids.
Slow loading provides time for fluids to escape from the tendon.
The slow heavy condition produced the greatest response in tendon thickness and stiffness.
Reducing compression during rehabilitation improves patient outcomes.
Patient satisfaction was significantly higher in the low compression group.
Applying a good load on the tendon is crucial for recovery.
Rest is essential in the early stages of tendon injuries.
Heavy slow and isometric exercises are well tolerated by patients.
The GhenTendon initiative aims to bridge clinical care and research.
Understanding intra-tendinous pressure is key to managing tendinopathy.
