Assistive tech helps paralysed man cycle competitively
Athletes with disabilities have been competing in a range of events that use assistive technology to overcome day-to-day practical challenges.
Bionic arms, powered exoskeletons, brain-controlled computer interfaces and supercharged wheelchairs all featured at the world's first Cybathlon, near Zurich, Switzerland.
One of the races saw functional electrical stimulation (FES) used to activate the leg muscles of paralysed competitors to ride bikes.
