  "account": "Scientists in Hong Kong and mainland China have created a battery-free, lightweight neural prosthesis that can help improve the mobility of people with difficulty walking, including stroke survivors. The device generates energy from the wearer's movements to stimulate their muscles, assisting ankle movement and restoring natural walking patterns. This could help prevent falls for stroke survivors, the elderly, and others with mobility impairments. The researchers published their findings in the journal Nature Communications on September 2. The device only requires a few steps to power up, and during trials, it increased stride length and walking speed in stroke survivors both indoors and outdoors. This improvement was \"immediate\" and didn't require complex setup. The system operates without external batteries, integrates into standard footwear, and needs minimal time to wear. Unlike rigid braces typically used for foot drop, this device works by facilitating movement rather than constraining the ankle joint. Foot drop, a common post-stroke impairment, reduces walking efficiency, increases fall risk, and limits quality of life. The device was inspired by natural gait patterns, with mechanical energy harvested from the unaffected limb powering a neurostimulator that helps the weaker leg contract. While foot drop was not completely eliminated, the device significantly improved gait. The researchers hope to make the device low-cost, easy to use, and lightweight, potentially benefiting people in low-income countries. They have also shown interest from elite Hong Kong athletes in using the device for training purposes.",
  "summary": "Scientists have developed a lightweight, battery-free device that could help improve the mobility of people with difficulty walking, such as stroke survivors. Developed by researchers in Hong Kong and mainland China, the neural prosthesis uses energy generated by the wearer’s own movements to electrically stimulate their muscles, helping to flex their ankle and restore their natural walking…",
