According to the National MS Society, about 2/3 of people living with multiple sclerosis (MS) have some level of difficulty walking. Problems with walking can interfere with work, travel, social events, and daily activities. Symptoms such as fatigue or spasticity can aggravate difficulties in getting around. Fortunately, many challenges with mobility can be alleviated by using mobility aids. These can be as simple as a cane or foot orthotic or as complex as a power wheelchair or adapted vehicle.
