Brain stimulation adapts to Parkinson's patients' every step, easing gait and falls

Article excerpt

UC San Francisco researchers have engineered a breakthrough in deep brain stimulation that shifts in real time as Parkinson's patients walk, dynamically adjusting to each step. Traditional DBS delivers constant electrical pulses to the brain; this new system detects gait patterns and tweaks stimulation on the fly. In early results, the adaptive approach improved walking stability and reduced falls, a major concern for Parkinson's patients, who face fractures and serious injury from tumbles. The advance suggests that one-size-fits-all brain stimulation may be outdated, and that precision medicine in neurology could mean the difference between mobility and confinement.
