In this thesis, a Dutch version of the Brief IPQ is presented to assess IPs in daily physiotherapy
practice in The Netherlands. Further, a literature overview of the existing associations
and prognosis of IPs on MSP and functioning is presented, and these associations in
primary physiotherapy care in The Netherlands are explored. The impact of a matched
care physiotherapy package, matched to dysfunctional IPs, and MSP and physical functioning is studied.
In this thesis, three themes (ie. measurement, association / prediction and treatment) are explored
for their contribution to physiotherapy management of MSP in general, and especially
for low back pain
