Summary: This study investigated the effects of eccentric loading exercises (ECC) and heavy slow resistance loading (HSR) on Achilles tendon force, finding that external load and maximum dorsiflexion angle are significant predictors of peak AT force. Standing position may be more effective for the same external load due to the rate at which peak dorsiflexion angle affects AT force being twice as high compared to seated position.

Summary: Mechanical overload is the main cause of Achilles tendinopathy, and compressive loads may also contribute to the pathophysiology. However, data on intratendinous pressures is lacking. This study found that intratendinous pressure increased during stretching and eccentric loading, with the highest pressures in the deep insertion region and during the eccentric heel-drop. These findings suggest that compression plays a role in Achilles tendinopathy and further investigation is needed to explore its management in patients.

Summary: Achilles tendon injury is a common condition that affects the biomechanical properties of the tendon and impairs its function. Recent research has focused on the role of growth factors in tendon healing, with clinical trials and animal experiments showing promising results. However, further studies are needed to determine the efficacy of these strategies.

Summary: This study aims to compare the effectiveness of a criteria-based rehabilitation program with strength and reactive strength targets to a successful rehabilitation program in reducing pain and improving function for patients with chronic mid-portion Achilles tendinopathy. Additionally, the study will assess changes in calf strength, reactive strength, and lower limb biomechanics over a 12-week rehabilitation program, along with long-term follow-up investigations.

Summary: This study investigated the impact of commonly used rehabilitation exercises and different twists on Achilles tendon strains, using subject-specific geometry and muscle forces. The findings suggest that different exercises and twists have varying effects on tendon strains, which can help clinicians prescribe rehabilitation exercises based on their desired impact on tendon strains.

Summary: This study investigated the effects of verapamil-loaded polydopamine nanoparticles on adhesion formation after Achilles tendon laceration and repair in rats. The results showed that VP-PDA nanoparticles reduced adhesion formation and improved tendon healing. As topical verapamil has been used clinically without side effects, VP-PDA nanoparticles have direct translational implications, although their anti-adhesive effects on intrasynovial tendon injury need further exploration.

Summary: This study investigates the effects of early tensile loading rehabilitation on nonsurgically treated Achilles tendon ruptures. The results show that early tensile loading does not lead to an increase in the elastic modulus of the healing tendon, but it does alter the structural properties by increasing tendon thickness.

Summary: The purpose of this study was to investigate the relationships between calf muscle function, tendon length and gait biomechanics in patients who underwent surgical treatment for chronic Achilles tendon rupture. The findings showed that better performance in the heel-rise endurance test was associated with faster walking speed, greater peak ankle power, shorter stance phase, and less peak ankle dorsiflexion angle during gait. In addition, greater Achilles Tendon Resting Angle (ATRA) was correlated with longer stance time, greater peak ankle dorsiflexion angle, fewer repetitions in the heel-rise test, and lower total work. These results suggest that greater calf muscle endurance is moderately correlated with better ankle biomechanics during gait in patients surgically treated for chronic Achilles tendon rupture.

Summary: This study developed an easy-to-use sling-based training set-up for home-based Achilles tendon and triceps surae muscle strength training and assessed its reliability and effectiveness in healthy men. The results showed that the home-based training set-up significantly improved muscle strength and jump performance, providing a new option for high-loading interventions.

Summary: This study conducted a systematic review to assess the load borne by the Achilles tendon during activities/exercises. The findings showed that the load on the tendon during walking ranged from 2.7 to 3.95 times body-weight (BW), while running resulted in a load of 4.15 to 7.71 times BW. The strengthening exercises varied in load from 0.41 to 7.3 times BW.

Summary: The study utilizes the reverse fragility index (RFI) to evaluate the neutrality of randomized controlled trials (RCTs) comparing the rerupture rates of acute Achilles tendon ruptures treated with open repair versus early functional rehabilitation. The findings indicate that changing the outcome status of only a few patients can reverse the statistical nonsignificance of studies reporting equivalent rerupture rates.
