Tokyo Tech's Yoshihiro Miyake and colleagues have developed an innovative, non-invasive therapeutic intervention that may improve the mobility, stability, and quality of life of Parkinson's disease patients.

The technology is also described in the August issue of Tokyo Institute of Technology Bulletin: http://www.titech.ac.jp/bulletin/index.html

The unintentional synchronizing of people's gait as they walk together is a familiar phenomenon. Understanding the mechanisms behind this synchronization could help people with a disturbed gait, such as patients suffering from Parkinson's disease. Research by Yoshihiro Miyake at the Department of Computational Intelligence and Systems Science at Tokyo Institute of Technology has helped to demystify the process and led to a new walking support device -- 'Walk Mate'.

Yoshihiro Miyake investigated coupled walking processes between a walking robot and a walking person. The study included people with a healthy gait and people suffering from Parkinson's disease or hemiplegia due to brain infraction. He used the timing of the walking person as a sensory input for the robot and the sound of a walking rhythm as the robot's output. An algorithm based on travelling wave dynamics controlled the timing difference between the Walk Mate's input and output.

The study revealed how people adjust their pace in response to the robot's audible output. Patients' stride patterns were healthier using 'Walk Mate' and they reported a greater stability and "sense of togetherness" compared with more traditional walking aids that have a fixed rhythm. Further studies in collaboration with researchers at the Max Planck Institute for Human Cognitive and Brain Sciences and the Department of Neurology at Kanto Central Hospital have underlined the great potential of the device.

"Our approach offers a flexible, portable, low-cost, non-invasive therapeutic intervention that may improve the mobility, stability, and quality of life of Parkinson's disease patients," say the inventors.
