(Kawasaki, Japan) An investigation by researchers in Germany and Japan has now demonstrated significant mobility improvements in spinal injury patients after training with the aid of a harness carrying a portion of their weight and a robotic hybrid assistive limb (HAL) exoskeleton designed by Cyberdyne, Inc., Japan. The researchers at Cyberdyne are affiliated with the Kawasaki INnovation Gateway at SKYFRONT, Japan.
Further information about science and technology projects at Kawasaki City is available in the Kawasaki SkyFront iNewsletter that highlights research being conducted by scientists and industries affiliated with Kawasaki INnovation Gateway at SKYFRONT (KING SKYFRONT)—the City’s flagship science and technology hub focused on open innovation in the life sciences and environment.
KING SKYFRONT is located on the opposite side of the Tama River that separates Tokyo International Airport (also known as Haneda Airport) and the Tonomachi district of Kawasaki. The Airport plays an important role in the globalization of the innovative activities of scholars, industrialists and City administrators based at KING SKYFRONT.

Robotic supported training helps chronic spinal patients recover
Loss of strength and coordination may inhibit the mobility of spinal injury patients long after recovery in the nervous system is complete. An investigation by researchers in Germany and Japan has now demonstrated significant mobility improvements in spinal injury patients after training with the aid of a harness carrying a portion of their weight and a robotic hybrid assistive limb (HAL) exoskeleton designed by Cyberdyne, Inc., Japan.
Researchers from BG University Hospital Bergmannsheil in Germany and the University of Tsukuba in Japan monitored eight patients who had all reached a chronic state in their condition so that further improvement was unlikely. The training consisted of 90 minute physiotherapy sessions 5 times a week for 90 days. Each session included treadmill training using the HAL exoskeleton. Electrodes placed on the muscles monitor potential differences, allowing the HAL to read these muscle signals and respond with support from the motorised exoskeleton. In addition around 50% of the patients’ weight was supported by a harness to prevent toe dragging or knee buckling.
The researchers assessed the mobility of the patients using the time up and go (TUG) test, which measures the time and assistance required to stand up from a wheelchair, walk 3 m, turn around and walk back. They also monitored the speed and distance covered during treadmill training.
