Essay

MS affects women more than men, and is most commonly diagnosed between the ages of 20 and 40. MS sufferers typically have problems of coordination and walking. The standard care for some sufferers is a plastic device affixed to the lower leg and ankle. In a recent test of this device, volunteers with MS were randomly assigned to two experimental groups.

Times, measured without the device (ND) and with the device (D), are presented below.
