Mobility is essential for quality of life and social participation. Some individuals with spinal cord injury have sufficient residual lower extremity motor control to walk. Improving walking function incorporates practice and training, and assistive devices or stimulation to augment function and balance. Overground robotic exoskeletons may have the potential to transform upright mobility in the future. Most individuals with spinal cord injury use a wheelchair for at least some of their mobility needs. Wheelchair skills training can open up new possibilities for participation. Regardless of the means of mobility, developing habits that protect joint health are essential for optimal lifelong mobility.
