But did they recover function? Brain activity is not a valid measurement for stroke rehab. 'Could' is not enough, does improve is the only acceptable answer, go back to the drawing board and do your research right to get stroke protocols out of it. Without an objective damage diagnosis you have no clue whom this might work on. Eg. me, with a massive dead area in the motor cortex and premotor cortex. If only stroke survivors were in charge we wouldn't waste all this stroke research.
Brain stimulation device could improve motor function after stroke
In a clinical trial of 30 patients who had survived chronic ischemic strokes, the transcranial rotating permanent magnet stimulator (TRPMS) produced significant increases in physiological brain activity in areas near the stroke site. Brain activity was measured using functional magnetic resonance imaging (fMRI).
Houston Methodist Hospital Eddy Scurlock Stroke Center director Dr David Chiu said: “The robustness of the increase in physiological brain activity was surprising. With only 30 subjects, a statistically significant change was seen in brain activity.”
Half of them were treated with brain stimulation, administered in 20 40-minute sessions over four weeks. The rest received a sham treatment.
Researchers analysed brain activity before, immediately after and one month after the therapy was administered and found that active treatment produced nine times greater increases in brain activity than the sham treatment.
Alongside this, the patients who underwent the TRPMS treatment demonstrated numerical improvements in five of six clinical scales of motor function. The scales measured gait velocity, grip strength, pinch strength and other motor functions of the arm.
