Summary: Eccentric strengthening shows significant short-term benefits in reducing pain and improving function for lateral elbow tendinopathy compared to other strengthening and pain-relieving modalities, with inconclusive long-term results. Further large-scale randomized controlled trials are needed to determine optimal treatment dosages, as the best care for lateral elbow tendinopathy is still in its early stages of development.

Summary: Runners with Achilles tendinopathy showed higher strike impulse, lower muscle strength of the plantar flexors, and higher clinical and functional damage compared to healthy runners and non-runners.

Summary: In patients with Achilles tendinopathy, traditional sonographic measures showed increased tendon thickness, hyperemia, and hypoechogenicity in the symptomatic tendon compared to the contralateral side. However, lower shear wave speed (SWS) was observed only in the free tendon, indicating localized alterations in tendon elasticity associated with Achilles tendinopathy.

Summary: This study aimed to investigate the factors related to the loss of muscle strength and range of motion (ROM) caused by eccentrically damaged muscle. The results showed that tissue hardness was correlated to a decrease in ROM, while muscle soreness was correlated to a decrease in muscle strength.

Summary: In the treatment of midportion Achilles tendinopathy, the Alfredson and Silbernagel loading programs showed no significant differences in clinical effects at 1-year follow-up, both leading to significant improvements in symptoms. Therefore, offering either program as a home-based training with limited supervision appears to be an effective treatment strategy.

Summary: Achilles tendinopathy is a challenging condition with limited effective therapies. This study introduced a novel mouse model of hindlimb muscle loading for targeted therapeutic exercise, showing promising results in improving biomechanical outcomes in a murine tendinopathy model. This model opens up possibilities for further research on how muscle loading can enhance healing of Achilles tendon injuries.

Summary: The study aimed to investigate the immediate effects of isometric plantarflexion exercises on Achilles tendon pain during a loading task, showing a small reduction in pain regardless of knee position. There were no significant differences between knee flexion and extension, suggesting both positions are effective for pain relief.

Summary: The study found that individuals with familial hypercholesterolemia had lower Achilles stiffness compared to controls, which seemed to be linked to Achilles loading rate rather than an increased strain. This suggests that individuals with familial hypercholesterolemia may use different Achilles loading strategies. Additionally, participants with familial hypercholesterolemia also demonstrated significantly greater Achilles hysteresis than the control group, indicating that walking may require a greater metabolic cost for these individuals.

Summary: This study evaluated the application of Extracorporeal Shockwave Therapy (ESWT) in patellar tendinopathy, Achilles tendinopathy, and plantar fasciitis, and assessed the evidence and effectiveness using the GRADE system. The results showed that ESWT has a negligible effect on pain and function in patellar tendinopathy and Achilles tendinopathy, but significantly affects pain and function in plantar fasciitis. The study concludes that ESWT has low effectiveness in patellar tendinopathy and Achilles tendinopathy, but high effectiveness in plantar fasciitis.

Summary: The unique structure of the Achilles tendon, which combines three smaller sub-tendons, enhances movement efficiency by allowing individual control from connected muscles. Factors like age-related compliance decrease and differences in sliding capacity between sub-tendons can affect the mechanical behavior and stress distribution within the whole Achilles tendon, highlighting potential clinical implications for personalized rehabilitation protocols.

Summary: During walking, increased stiffness in the Achilles tendon did not affect its function. While stiffness did not change with training, other parameters also showed no significant differences, which may help explain previous mixed intervention results and guide future investigations.

Summary: This article reviews the treatment methods for two common types of Achilles tendinopathy (AT). For midportion AT, eccentric exercise, isotonic exercise, and acupuncture showed the best effects. For insertional AT, extracorporeal shockwave therapy and eccentric exercise had the best outcomes. Combining different treatment methods can further improve pain, function, and patient satisfaction.

Summary: This study investigates the relationship between Achilles tendon forces and self-reported pain in runners with Achilles tendinopathy (AT) during rehabilitation exercises. The findings indicate that Achilles tendon forces can be estimated during common exercises and correlated with pain. Based on the results, an exercise progression hierarchy can be proposed to guide the treatment of runners with AT.

Summary: This study found that additional eccentric exercise significantly improved pain reduction and muscle strength in patients with LET compared to adjuvant therapy alone, and the eccentric exercise group showed better pain reduction compared to the concentric or isotonic exercise group.

Summary: Women with patellofemoral pain demonstrated deficits in both maximal muscle strength and rate of torque development of knee extensor and hip abductor during isometric, concentric, and eccentric contractions, highlighting the importance of addressing different aspects of muscle function through exercise therapy.
