Dear Kevin I would like to draw your attention to an interesting article re. VAS The reference is Collins et al (1997), Pain 72; 95-97 The aim was to establish at what point on the VAS moderate pain was represented. It used data from 1080 pts from RCT's of various ananlgesics and found that 1)Of the pts reporting moderate pain, 85% scored over 30mm on VAS 2) Of pts with severe pain, 85% scored over 54mm Using these results for my recent pain study I divided the VAS down into Mild Pain 0-3, Moderate pain 4-6, Severe pain 7-10. This is helpful as a junp from 7-5 is probably more clinically significant than a jump from 10-8. My particular interest is cancer pain and the above findings are similar to another article by Serlin et al (1995), Pain 61; 277-284. Hope this helps Karen (research physio) >From: "kevin reese" <[log in to unmask]> >Reply-To: [log in to unmask] >To: <[log in to unmask]> >CC: "Manual Therapy" <[log in to unmask]> >Subject: Pain measures >Date: Sat, 17 Apr 1999 11:46:22 +0100 > >WITH APOLOGIES FOR CROSS REFERENCING > >Dear listers > >Help !
