The Medicol 2025 congress challenges us on the medicine of tomorrow. By exploring applications dedicated to communication, we will see how doctors and therapists can use new technologies for their patients. To be able to better adapt to patients’ expectations, it is also a question of better understanding their functional capacities. The study of movement and in particular gait analysis is easier to carry out today and opens the way to a new generation of functional assessments. This diagnostic step in a more global framework strengthens the climate of doctor-patient trust, makes it possible to document the follow-up and to raise the patient’s awareness in their care.
