Achilles Tendinopathy, Treatment With eXercise Comparing Men and Women

Study Purpose

This study will evaluate if there is a difference in recovery of tendon structure and mechanical properties between males and females with Achilles tendinopathy receiving exercise treatment. It will evaluate recovery of tendinopathy with exercise intervention using outcome measures for tendon structure and mechanical properties along with validated measures of muscle-tendon function and symptoms.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

No
Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

NCT03523325
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

Achilles tendinopathy has an incidence rate of 2.35 per 1000 in the general population and is most prevalent in middle-aged individuals (35-55 y/o), but occurs in men and women of all ages. The primary symptom is pain during daily activities such as walking and exercising such as running. Aside from the pain, Achilles tendinopathy has been shown to significantly decrease physical activity level, resulting in further negative effects on overall health and well-being. The treatment for Achilles tendinopathy with the highest level of evidence is eccentric exercise, providing mechanical loading of the muscle-tendon unit. In a recent systematic review, all studies reported significant improvements in patient-reported symptoms but at 12 weeks the means ranged from 69-80 (100 being fully recovered) indicating that even with the most effective treatment individuals continued to have symptoms. At this time, other more invasive interventions such as injection therapies (ex. platelet-rich plasma) and surgery are recommended for patients who fail exercise treatment despite a lack of understanding of what factors are related to continued problems. Just achieving a reduction in pain and symptoms with treatment also does not ensure resolution of the tendon's structural abnormalities. In fact, studies evaluating the recovery of tendon structure with exercise suggest that at least 24 weeks may be needed to observe a significant change. Other individual factors such as sex, degree of tendon structural damage and functional deficits are also proposed to influence both the time course and success rate of recovery. The long-term goal of our research is to advance understanding of tendon injuries and repair, enabling tailored treatments to be developed. This study begins to address this long-term goal by evaluating the time-course of recovery in terms of tendon structure (ultrasound imaging) and viscoelastic properties (elastography) along with symptoms (patient-reported outcomes) and muscle-tendon function (functional test-battery) in males and females with Achilles tendinopathy treated with an exercise program. Aim 1 is to evaluate if there are differences in change over time in symptoms, muscle-tendon function, tendon structure, and mechanical properties between males and females with Achilles tendinopathy receiving exercise treatment. Aim 2 is to investigate whether the presence and magnitude of tendon structural abnormality at baseline will affect the ability and time-course of recovery with exercise treatment for Achilles tendinopathy. Aim 3 is to explore if patients who continue to have symptoms at the 16-week evaluation will further improve in symptoms, muscle-tendon function, tendon structure and mechanical properties over the course of one year.
