Evaluation of a PREHABilitation Protocol Using Adapted Physical Activity (APA) for Multiple Myeloma Patients Eligible for Intensive Autologous Stem Cell Transplantation Treatment

"Patients will have 3 sessions a week: 1 strengthening session and 2 endurance sessions.~For each session, patients will choose the exercises to be performed from the exercise booklet or the videos and records their observations in the patient notebook.~Depending on the treatment plan, patients will have alternating supervised (in hospital) and unsupervised (at home) APA sessions, in order to follow the rhythm of their visits to the department.~Each session will last 45 minutes with a medium intensity according to the Borg scale."

Patients will not be practising adapted exercises as part of the study. They will be treated with chemotherapy according to standard practice.
