Having spent his whole life as an athlete 39 year-old Mark Pollock, breaking his back and able to walk after 4 yrs, was thrilled to get back to doing an aerobic workout. The robotic device enabled the man to control his leg muscles voluntarily and take thousands of steps which is widespread news now.
The team used physical rehabilitation exercises and electrical stimulation therapy, achieved through an invasive epidural stimulator that they implanted into the patient's spinal cord. This latest research combines a new noninvasive spinal stimulation technique with a battery-powered wearable bionic suit. Pollock has become the first person to achieve voluntary control with a robotic device that aims to enhance mobility. Data capture from the robotic device enables researchers to measure to what degree a patient is moving their limbs themselves, and how much is done by the device.
Pollock was actively and voluntarily flexing his left knee and raising his leg both during and after electrical stimulation, working with the robotic exoskeleton to produce these movements rather than leaving the device to do all the work.
