Problems with socialism and equality are among the most common causes of stroke. Scientists at the Max Planck Institute for Human Understanding and Neuroscience in Leipzig, the Halle University Medical Center, and the Charité -Universitätsmedizin in Berlin have found that brain development helps. The direct position, which is used by the electronic devices attached to it, results in improved patient mobility. In addition to showing symptoms manifested after a single application, research suggests that treatment may need to be tailored individually to specific patients for best benefit.

Hand injuries are one of the most common causes of brain damage, for example, after a stroke. Victims are often unable to use their hands at all. Failures depend on the identification of changes in the anatomy and brain systems. These changes are caused primarily by direct damage caused by stroke, but also extend to other areas due to the way the brain is designed. “The mechanism of these changes is both the brain’s repair and the system of normal functioning after stroke. With the help of transcranial direct current stimulator (tDCS), which can influence these changes in the brain. enter the brain. brain tissuewhere they have a local gym or inhibitory effect“said Bernhard Sehm, director of the research team at the Max Planck Institute for Human Understanding and Neuroscience in Leipzig and chief physician at the University Clinic and Polyclinic for Neurology at the Halle University Medical Center. He and Toni Muffel of Charité in Berlin have studied how this method is effective for the rehabilitation of stroke patients and recently published their results in the journal Strengthen the Brain.

“Our study included 24 patients who had limited mobility due to stroke. In the laboratory we have statue system which can be adjusted individually for each patient, a type of exoskeleton that allows them to move their paralyzed hands and perform tasks in virtual environment“Muffel, the first author of the study explains. As patients interact with virtual objects, their brain moves electronically on the skin.” In parallel, we measured how well, or less, excellence, brain energy helped the participants perform the tasks. “

The result? Brain damage has a profound effect on areas of the brain affected by stroke. “Our robotic system allows us to measure the performance of different vehicles at the same time and thus we can get a complete picture of the impact of the movement. tDCS, “said Bernhard Sehm. “However, we could not find a consistent regulatory framework among different patients. Instead, changes in areas of the brain vary depending on the operation and electrical configuration. This means that in the future, patients will need to be thoroughly examined before exercise therapy to improve the system targeted by individuals regarding their shortcomings. This simple but exciting way of strengthening the brain will find its way into the future patient care“said Bernhard Sehm.
