Usual care
Usual care consisted of physiotherapy referral by the medical doctor if indicated. As in usual clinical practice, it was ultimately up to the patient to decide whether or not to visit the physiotherapist. Both the content and duration of the physiotherapy treatment could vary based on the needs of each individual patient, and were decided by the medical specialist and physiotherapist in consultation with the patient. During study visits, the outcome assessor routinely monitored if and how often each participant had visited their physiotherapist, and what components (i.e., strength training, mobility exercises, balance exercises) were included in the physiotherapy treatment.
