For quadriplegics, life can be extremely isolated. Those without the ability to control their arms, legs or head must rely entirely on a caregiver to move, or even turn around, their wheelchair.
One cause of quadriplegia is the neurodegenerative disease ALS, which afflicts an estimated 12,000 to 15,000 in the U.S., according to the CDC.
Because the disease is progressive, those afflicted can go from having completely normal motor control to being fully quadriplegic without the ability to talk, in the span of just a few years. Previously having the ability to move independently can make the loss of movement even more difficult for those with ALS.
