Patients will be asked to wear this step counter every day during the intervention;~3. smartphone coaching application (mPAC), installed on a smartphone and linked to the step counter, will provide automated coaching by displaying an individual activity goal (expressed as daily step count) and daily and weekly feedback on the performance (steps) of the patient.~4. phone calls by the coaches initiated in pre-defined situations (non-compliance with wearing the step counter, failure to transmit the data, failure to progress).~Evidence-based behaviour change techniques will be implemented."
