This RCT is in line with earlier studies highlighting the positive effects of early mobilisation and movement for hospitalised people. It also confirms that individualised interventions are beneficial to patients.
The intervention group was supervised by a trained nurse who is experienced in geriatric care. This is due to the fact that according to the Italian national health system, no physio- or occupational therapists are assigned to geriatric units. This is however not necessarily the case in every country.
Whether IAWP intervention is provided by nurses or physiotherapists does not really matter here: the positive effects may be obtained with the assistance of (trained) health professionals caring for hospitalised patients in geriatric units as the whole staff may positively affect movement and walking. Of course physiotherapists, when operating in such units, have a key role to play in these types of intervention improving walking ability.
