Progress for Paraplegics

10-25-12

Joel W. Burdick, Richard L. and Dorothy M. Hayman Professor of Mechanical Engineering and Bioengineering, and Yu-Chong Tai, Professor of Electrical Engineering and Mechanical Engineering, are developing new technologies to expand their research which has enabled a paraplegic man to stand and move his legs voluntarily. The team has until now used intelligent guesswork to determine which stimuli might work best. But soon, using a new algorithm developed by Professor Burdick, they will be able to rely on a computer to determine the optimum stimulation levels, based on the patient's response to previous stimuli. This would allow patients to go home after the extensive rehab process with a system that could be continually adjusted by computer. [Caltech Release] [ENGenious Progress Report]

Professor Burdick Receives Popular Mechanics Award

10-12-11

Joel W. Burdick, Professor of Mechanical Engineering and Bioengineering, and colleagues are recipients of a 2011 Breakthrough Award by Popular Mechanics for their work that helped a paralyzed man stand. The Breakthrough Innovator Awards are in recognition of "innovators whose inventions will make the world smarter, safer, and more efficient in the years to come."

Stimulating Electrode Array Assists Paraplegic Man to Stand and Move Legs Voluntarily

05-20-11

Joel W. Burdick, Professor of Mechanical Engineering and Bioengineering, and colleagues including Yu-Chong Tai, Professor of Electrical Engineering and Mechanical Engineering, have used a stimulating electrode array to assist a paralyzed man to stand, step on a treadmill with assistance, and, over time, to regain voluntary movements of his limbs. Using a combination of experimentation, computational models of the array and spinal cord, and machine-learning algorithms, Professor Burdick and his colleagues are now trying to optimize the stimulation pattern to achieve the best effects, and to improve the design of the electrode array. Further advances in the technology should lead to better control of the stepping and standing processes. [Caltech Press Release]
