Magnets Might 'Unlock' Paralyzed Arm After Stroke

People who suffer a stroke face many physical and emotional hurdles on their long road to recovery. Researchers have found that strong pulses of magnetic energy to the brain, called transcranial magnetic stimulation (TMS), can be used as probes to identify undamaged, untapped brain regions that may be recruited to move the arm. The stimulation did not cure stroke patients of their paralysis.
