Brain-computer interface training for phantom limb pain

Takeaway

  • Phantom limb pain can be effectively reduced using brain-computer interface (BCI) training.

Why this matters

  • Phantom limb pain is a common complication following the amputation of a limb which has a large impact on quality of life.

  • A previous study showed that training patients to use a BCI to control an image of the phantom hand reduced pain compared with sham training; however, a large-scale randomized trial is needed to confirm these results.
