Takeaways

Gabriel Fernandes is a physiotherapist with a focus on calf muscles and tendons. Research indicates that the lateral gastrocnemius may play a more significant role in Achilles tendinopathy than previously thought. Cortical inhibition affects muscle force production, particularly in individuals with tendinopathy. Endurance deficits are commonly observed in patients with Achilles tendinopathy, impacting their rehabilitation. Rehabilitation strategies should consider specific muscle contributions and include targeted exercises for the lateral gastrocnemius. Foot positioning during exercises can influence muscle activation and should be tailored to individual needs. Eccentric training may help improve muscle function and reduce inhibition in affected muscles. Neurophysiological assessments can provide insights into muscle drive and function in tendinopathy patients. Future research should explore the relationship between muscle fatigue and tendinopathy more deeply. Collaboration between clinicians and researchers is essential for advancing treatment strategies.
