Mechanical overload is considered the main cause of Achilles tendinopathy. In addition to tensile loads, it is believed that the Achilles tendon may also be exposed to compressive loads. However, data on intratendinous pressures are lacking, and consequently, their role in the pathophysiology of tendinopathy is still under debate. Therefore, we aimed to evaluate the intratendinous pressure changes in the Achilles tendon during stretching and eccentric loading. Twelve pairs of human cadaveric legs were mounted in a testing rig, and a miniature pressure catheter was placed through ultrasound-guided insertion in four different regions of the Achilles tendon: the insertion (superficial and deep layers), mid-portion, and proximal portion. Intratendinous pressure was measured during three simulated loading conditions: a bent-knee calf stretch, a straight-knee calf stretch, and an eccentric heel-drop. It was found that the intratendinous pressure increased exponentially in both the insertion and mid-portion regions of the Achilles tendon during each loading condition (p < 0.001). The highest pressures were consistently found in the deep insertion region (p < 0.001) and during the eccentric heel-drop (p < 0.001). Pressures in the mid-portion were also significantly higher than in the proximal portion (p < 0.001). These observations offer novel insights and support a role for compression in the pathophysiology of Achilles tendinopathy by demonstrating high intratendinous pressures at regions where Achilles tendinopathy typically occurs. To what extent managing intratendinous pressure might be successful in patients with Achilles tendinopathy by, for example, avoiding excessive stretching, modifying exercise therapy, and offering heel lifts requires further investigation.

Eccentric exercise is more effective than other exercises in the treatment of mid-portion Achilles tendinopathy: systematic review and meta-analysis

Achilles tendinopathy (AT) is one of the most frequent overuse injuries in the ankle. The evidence base for its conservative management AT continues to evolve, but there is still a gap in the evidence for the efficacy of any modality of treatment in high-quality studies. This systematic review and meta-analysis investigated the efficacy of EE in improving pain and function in adult patients with mid-portion Achilles tendinopathy compared to other forms of exercise. A search was performed in PubMed, BIREME, SportDiscus, Cinahl, Web of Science and PEDro, in November 2022. The methodological quality was evaluated using the Risk of Bias 2 tool (RoB2) of the Cochrane collaboration, and the meta-analysis was performed using the Review Manager 5.1 program. 2024 articles were identified and eight fulfilled the inclusion criteria. RoB2 presented a final score with 62.5% of the studies presented “some concerns”, and 37.5% (five and three articles, respectively) presenting “high risk” of bias. EE was effective for the managment of AT. The only variable for which a meta-analysis was possible was pain (five articles), analysed with the visual analogue scale/numerical visual scale. The mean difference (MD) in treatment effect using EE was − 1.21 (− 2.72 to − 0.30) with a 95% of confidence interval (CI), thus identifying a significant positive effect for the improvement of pain in patients with AT in whom EE was used. EE is effective in the management of AT. The meta-analysis shows the need for appropriately powered randomized controlled trials with better design, the use of standard outcome measures and well-planned protocols for conservative management of AT

"I've got a spring in my step" participants experience of action observation therapy and eccentric exercises, a telehealth study for mid-portion Achilles Tendinopathy: a qualitative study
Deirdre Ryan et al
J Foot Ankle Res. 2023 Apr 11;16(1):19

Background: Quantitative research has dominated the field of Achilles Tendinopathy. The use of qualitative research allows in-depth exploration of participants' perspectives, offering great insight in the evaluation of a trial's processes, particularly when exploring a novel intervention such as Action Observation Therapy combined with eccentric exercises which has not been previously researched. This study aimed to qualitatively explore participants' experiences of partaking in a telehealth study including the acceptability of the intervention, motivators for participation, and perspectives on the trial processes.

Method: A thematic analysis as guided by Braun and Clarke was used to analyse the semi-structured interviews conducted on a purposive sample of participants with mid-portion Achilles Tendinopathy who recently completed a pilot feasibility study. The study adhered to the criteria for reporting qualitative research guidelines (COREQ).

Results/discussion: Sixteen participants were interviewed. The five themes identified were: (i) The impact of Achilles Tendinopathy is commonly not prioritised with 'The acceptance and minimisation of pain' as a sub-theme (ii) Therapeutic alliance has the greatest impact on support (iii) Factors which influenced adherence (iv) Action Observation Therapy is valued and recommended (v) Recommendations for future interventions.

Conclusion: This study provides insightful recommendations around; exploring the use of Action Observation Therapy in Achilles Tendinopathy, the relative importance of therapeutic alliance rather than mode of therapy delivery, and that sufferers of Achilles Tendinopathy may not prioritise health seeking for this condition.
