We designed a conceptual framework, guiding the development and content validation of two patient reported outcome (PRO) instruments on physical activity (PROactive PRO instruments).
The opportunities for the applications of biophysics seem limitless because the lengthy delay between the development of a research instrument and its application means that many scientific instruments based on physical principles already known will be shown to have important potential for medicine.
