Severe hand and arm weakness can make using a conventional computer keyboard and mouse impossible. Eye-tracking and head mouse technology can help, but if you have adequate lower-body strength, it may be worth letting your feet give you a hand. Foot controls — including trackball and rollerball mice, programmable foot pedals and foot switches — offer viable options for maintaining computer access.
