Control intervention
Physical therapists were instructed to provide their usual care according to the Dutch physical therapy guideline (i.e., standard, ‘non-stratified’ exercise therapy accompanied by patient education).In the Netherlands, a maximum of 12 physical therapy sessions and a maximum of 180 min of dietician consultations per year are reimbursed from the ‘basic’ health insurance package for people with knee OA, from which patients are obliged to pay the first €385 themselves. In addition to the ‘basic’ health insurance package, people opt for supplementary health insurance to cover healthcare cost that are not (fully) covered by the basic health insurance package.
