INNOVATION FOR INDEPENDENCE

ISSUE 82 DECEMBER 2011/JANUARY 2012 £6.95

European debut for military inspired device By Dominic Musgrave AN EXOSKELETON that allows paraplegics to walk using technology based on military research has made its European debut. Ekso Bionics (formerly Berkeley Bionics) has been trialling the electronic suit ‘Ekso’ in the US since 2010 and now hopes to roll it out in rehabilitation centres and eventually homes in Europe, following its launch at the London International Technology Show. The current Ekso model is remotely controlled by an operator walking behind the user, but the company plans to unveil a fully independent model powered by artificial intelligence next year. The firm’s chief executive officer Eythor Bender said: “Many wheelchair users continue to live very active lives but as they research their options for increased mobility they discover that wheelchairs are the only real option. “This has been the only alternative for nearly 500 years. We want to enhance their independence and freedom of movement, and with Ekso Legs they now have the option to stand and walk for the first time since their injury.” Ekso Legs can be adjusted to fit most people between 5 ft 2 and 6 ft 2, weighing up to

220 pounds in a matter of minutes. Users must be able to self-transfer from their wheelchair. Straps secure Ekso Legs safely to the user, over their clothing and shoes. The wearable robot provides unprecedented knee flexion, which translates into the most natural human gait available in any exoskeleton today. The device is battery-powered and uses a gesture-based human-machine interface, which utilising sensors, observes the gestures the user makes to determine their intentions and then acts accordingly. A real-time then computer draws on sensors and input devices to orchestrate every aspect of a single stride. Eythor added: “The biggest challenge was developing a frame that transferred the weight completely to the ground. “After that we started applying power to it to get more strength and increasing endurance.” To date, nearly 100 people in the US have walked in the device. In the UK and Europe it will initially be used in spinal cord Injury rehabilitation centres under clinical supervision. The ultimate aim is to create a personal device that can be safely used in the home, to be worn throughout the day as early as 2013.

A 10-year-old girl who lost her legs to meningitis at the age of two wore a special pair of prosthetic ones for the annual Remembrance Sunday ceremony in Whitehall. Lydia Cross, who has raised more than £60,000 for war veterans, had a special pair made by Bob Watts at Dorset Orthopaedic with poppies on after being invited to attend the event by the Rotary Club.
