There is provided a method for identifying a sit-to-stand transfer in measurements of the movement of a user, the method comprising obtaining measurements of the vertical acceleration experienced by the user during movement; obtaining measurements indicating changes in height of a part of the user during movement; processing the measurements of the vertical acceleration to identify candidate movements corresponding to a sit-to-stand transfer by the user; and determining an identified candidate movement as a sit-to-stand transfer where the identified candidate movement coincides with an increase in height. A corresponding apparatus and computer program product are also provided.
