www.bodyinmind.com.au Copyright GL Moseley 2009 Does it feel like it is mine? Many patients report feelings of foreigness & hostility towards the limb. “I feel like it is not mine, like it is an imposter” Lewis et al 2008 Pain

www.bodyinmind.com.au Copyright GL Moseley 2009 In chronic CRPS, you have to stimulate the affected hand about 25ms before the other to think the stimuli occurred at the same time Moseley et al 2009 Brain (published on-line 150909)

www.bodyinmind.com.au Copyright GL Moseley 2009 But when you cross your arms, the opposite occurs - you have to stimulate the UNaffected 20ms before the affected to think the stimuli occurred at the same time Moseley et al 2009 Brain (published on-line 150909)

www.bodyinmind.com.au Copyright GL Moseley 2009 This shows that the bigger the shift in processing, the colder the limb is, relative to the opposite one. The shift away from the affected limb is opposite to what we see with acute threatening stimuli Van Damme et al 2009 Brain Res. 2009;1253:100-106. Moseley et al 2009 Brain (published on-line 150909)
