Some amazing technological advances are having a profound and positive effect on individuals suffering from spinal cord injury. Bionic research has led to the development of assistive devices which strap directly onto an individual’s body. These devices enable movement and provide the wearer with much greater freedom of movement and control over their environments.
One of the most exciting advances is an apparatus which enables paraplegics walk upright and even go up stairs. The initial research into these devices, which are called bionic suits or external skeletons (exoskeletons), was focused on developing assistive technology to help soldiers carry heavier loads and save energy.
The rehabilitative and medical benefits quickly became apparent and research expanded into uses for individuals who were paralyzed, or had lost limb function due to stroke or injury. One of the leading manufacturers of these suits, Eksobionics, describes how their device works:
“Walking is achieved by the user’s weight shifts to activate sensors in the device which initiate steps. Battery-powered motors drive the legs, replacing deficient neuromuscular function.”
Other devices in development by various companies assist with daily activities, such as eating, by controlling hand and arm movement.
What’s it Like to Wear One?
Users of the suits describe their experience as profoundly liberating. The sensation of standing upright and being able to move in the environment without having to worry about an entirely wheel chair accessible route provides greater freedom. Moving in these suits also helps with circulation and the prevention of contractures.
Limitations
There are still many opportunities for the devices to improve. The bionic suits require a significant amount of power, and the wearer has to have a reliable battery pack and recharging source before taking it into the community. They are slow and noisy, so the types of activities that can be performed are limited. There is also a risk of skin irritation and breakdown from pressure and friction points while wearing the suit, especially for individuals who do not have skin sensation. Careful checks and adjustments are needed to make sure tissue damage doesn’t occur.
Despite these drawbacks, end users are enthusiastic about their experience. With continued research this promises to be an area which can greatly improve the quality of life of many spinal cord injury victims.
