“…As in other settings, pain intensity is best assessed using patient self-report measures such as VASs (Galinski et al, 2005;Kober et al, 2002), VNRSs (McLean et al, 2004;Woollard et al, 2004;Rickard et al, 2007;Bounes et al, 2008), VDSs (McLean et al, 2004;Vergnion et al, 2001), faces pain scales (Rogovik & Goldman, 2007) (see Section 2). A ruler incorporating both visual analogue and faces pain scales (Lord & Parsell, 2003 Level IV) has also been used to measure pain in patients prior to arrival at hospital.…”
