Tactile direction discrimination after stroke

Takeaway

  • Tactile direction discrimination (TDD) dysfunction post-stroke is associated with lesions in prefrontal cortical, insular and somatosensory brain regions; in addition, wider neural networks including subcortical and white matter regions might be involved.

Why this matters ?

  • Tactile sensation is vital for daily function, and previous imaging studies suggest that a complex cortical network is involved in directionality discrimination of tactile stimuli in healthy individuals.

  • Greater clinical understanding of the underlying mechanisms of tactile dysfunction post-stroke could have a beneficial impact on rehabilitation therapy for stroke patients.
