Welcoming back my arm: affective touch increases body ownership following right hemisphere stroke

Takeaway

  • Affective touch may reduce the unusual, sensory symptoms often reported by right hemisphere stroke patients, in particular “feelings of deafference”.

Why this matters

  • Several disturbances of body awareness occur after right hemisphere stroke, including feelings of non-belonging or non-recognition of the limb and delusional ideas of disownership (DSO).

  • This is the first study to show that receiving affective touch can increase the sense of arm ownership in right hemisphere stroke patients with DSO.
