This is the application required to collect data from the Montreal research project on the effects of eccentric strengthening exercises in adults with Achilles tendinopathy.

In this app, you will find a video showing you how to do the Achilles tendon strengthening exercise.

In addition, you will have to register each week:
- The times when you do your Achilles tendon exercises;
- Your pain on a scale of 0 to 10;
- Your physical activity minutes.

For any questions on the use of the application, you can contact the research team.
