@SHestehave Thanks! Let's see how the sunrise compares

[Axel Vittersø @AVitterso]

Looking forward to attending my first conference in ages..!

Come by my poster #38 on Friday to find out about the Causal effect of opioid drugs on body representations.

Some exciting findings to discuss!

[BRNet - @bodyrepnetwork.bsky.social @bodyrepnetwork]

The BRNet Conference is just around the corner! We look forward to welcoming you all in Verona on September 12th and 13th #BRNet2024

[Axel Vittersø @AVitterso]

Highly recommended PhD supervisor and funding scheme!

[Janet Bultitude @JanetBultitude]

Please share this PhD opportunity, working with myself, @SamNeuroPain, @JenStephDavies, and Prof Tony Pickering across four institutions. Four years funding plus generous research and training allowance to study CNS changes in pathological pain. https://t.co/DQUvACG2tO

Very pleased to share this fabulous #openaccess paper on prism adaptation for hemispatial neglect, and first first-author publication by @OrsolyaSzkely1 (based on her MSc(!) dissertation with @mcintord) @BathPsychology @UniofBath @TeuniTenBrink 1/n

[Janet Bultitude @JanetBultitude]

Very pleased to see that our RCT of prism adaptation received the highest quality rating (93%) in this review of 38 trials of non-pharmaceutical treatments for #CRPS.

@DrGBuckingham @LCHeathcote @Kingspsychol @JoeChilcot @joaomineiro07 It is! I went twice and had a lot of fun :)

@CaitlinENaylor @JanetBultitude @DrGBuckingham @MichaelProulx @UniofBath @BathPsychology @GW4BioMedDTP Thanks!
They are (to a degree) use dependent. Amputation, immobilization, or disuse could cause them to change, also at a cortical level. They need to keep up with all the "structural" changes our bodies go through (e.g. growth spurts, pregnancy, gaining weight).

@AsafKlaf @JanetBultitude @DrGBuckingham @MichaelProulx @UniofBath @BathPsychology @GW4BioMedDTP I look forward to reading your paper and coming back to you about the philosophical/linguistic subtleties ☺️

[Axel Vittersø @AVitterso]

@AsafKlaf @JanetBultitude @DrGBuckingham @MichaelProulx @UniofBath @BathPsychology @GW4BioMedDTP Yes, in some cases the terms pain and nociception might be confused. But if, as Harris proposed, pain has a cortical origin, then there is not (necessarily) any nocociception, as there are no nociceptors in the brain.

[Axel Vittersø @AVitterso]

@jorgejimenez280 @JanetBultitude @DrGBuckingham @MichaelProulx @UniofBath @BathPsychology @GW4BioMedDTP The theory proposes that the affective experience of pain arises due to sensorimotor conflict, a bit like how motion sickness is caused by multisensory conflict (i.e. visual and vestibular).

[Axel Vittersø @AVitterso]

@AsafKlaf @JanetBultitude @DrGBuckingham @MichaelProulx @UniofBath @BathPsychology @GW4BioMedDTP I think it is more helpful to think of it as a way of describing the function that pain has, rather than the concept itself, which, I agree, is covered by the IASP definition :)

[Axel Vittersø @AVitterso]

@AsafKlaf @JanetBultitude @DrGBuckingham @MichaelProulx @UniofBath @BathPsychology @GW4BioMedDTP In that sense, the pain itself becomes a pathology of the central nervous system. And this is what is typically referred to as pathological pain.

[Axel Vittersø @AVitterso]

@drnagu2008 For more detail check out section 2.7.2 😉

[Axel Vittersø @AVitterso]

@drnagu2008 There is evidence that graded motor imagery, sensory discrimination, visual feedback, and mirror therapy can reduce pain, and they may do so by normalizing body/motor representations, improving the availability of sensory information and/or reducing sensorimotor conflict

[Axel Vittersø @AVitterso]

In contrast, treatments that target sensorimotor process can alleviate pain. Therefore, we think that sensorimotor conflict might help to maintain, rather than cause, pathological pain.

[Axel Vittersø @AVitterso]

Although sensorimotor changes were evident in many painful condition, there was very limited evidence that inducing sensorimotor incongruence can cause pain.
