Brief Summary

To this day, the most accepted treatment for the Achilles tendinopathy (AT) remains the exercise program to strengthen the plantar flexor muscles. The eccentric exercises protocol proposed by Alfredson is the most popular and recommended one by the rehabilitation professionals. Currently, the response to interventions is measured almost exclusively by clinical data, especially using questionnaires, since the Quantitative Ultrasound (QUS) is rarely used. In fact, the thickness of the Achilles tendon, which is generally the only measure noted when using musculoskeletal ultrasound on AT, does not allow the clinician to confirm an improvement following an eccentric exercise program if the tendon is thinner, especially in adults with chronic AT. No scientific evidence indicates whether there is an improvement in the biological integrity of the Achilles tendon following the completion of Alfredson's eccentric strengthening protocol. This is why it seems relevant to use the pre-established minimal biomarker data set obtained with the QUS in order to study the variation of these data in response to a rehabilitation intervention and to verify how these variations influence clinical data.

Outcome Measures

Primary Outcomes (1)

  • Responsiveness of a minimal data set of measures obtained with the QUS (quantitative ultrasonography)

    The primary objective is to determine the responsiveness of a minimal data set of measures obtained with the QUS that characterize the biological integrity of the Achilles tendon (mean thickness, echogenicity, variance, homogeneity at 90 degrees, mean thickness, echogenicity and average homogeneity), after participants have completed the 12-week exercise program.

    12 weeks

Secondary Outcomes (1)

  • Persistence of the QUS measures' modification at 3 months post-intervention

    12 weeks

Other Outcomes (3)

  • Association between the QUS measures' modification and changes in the visual analog pain scale

    24 weeks

  • Association between the QUS measures' modification and changes in the Victorian Institute of Sports Assessment-Achilles questionnaire

    24 weeks

  • Association between the QUS measures' modification and changes in the Lower Extremity Functional Scale

    24 weeks

Study Arms (2)

Injured Achilles tendon participants who have an Achilles tendinopathy

They will do the eccentric exercise protocol and go through a series of ultrasound examination.

Other: Eccentric strengthening exercises of the Achilles tendon

Healthy Achilles tendon (contralateral) of participants who have an Achilles tendinopathy

They will do the eccentric exercise protocol and go through a series of ultrasound examination.

Other: Eccentric strengthening exercises of the Achilles tendon

Interventions

This exercise will require the completion of slow active eccentric plantar flexion exercises with the forefoot positioned over the edge of a step. These exercises will be repeated twice daily (three sets of 15 repetitions with the knee in extension and three sets of 15 repetitions with the knee in flexion) during a three-month period. The amount of loading will be calibrated and progressed on a weekly basis by the physiotherapist according the participant's perceived effort and pain intensity.

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodProbability Sample
Study Population

Participants will be recruited from patients with symptoms consistent with AT in the middle third of the Achilles tendon for at least six weeks. They will be recruited from physical therapy clinics, sports medicine clinic, sports teams and athletic clubs.

You may qualify if:

  • Symptoms consistent with AT in the middle third of the Achilles tendon for at least six weeks
  • AT signs objectified by the physical exam and the ultrasound imaging at the initial evaluation
  • At least 18 years old
  • Victorian Institute of Sport Assessment-Achilles Questionnaire (VISA-A) score below 90
  • have pain of at least 3 out of 10 according to the analog visual scale during athletic activities

You may not qualify if:

  • Pain at the Achilles tendon enthesis
  • A complete rupture of the Achilles tendon History of Achilles tendon rupture Inflammatory arthropathy
  • Sign of neurological lesion on physical examination of the lower limb
  • Neurological disease (e.g. multiple sclerosis, stroke)
  • History of intervention of the Achilles tendon or ankle (e.g. surgery, cortisone infiltration, extracorporeal shock waves therapy, platelet-rich plasma injection).
