The Cleveland Clinic:

Precise measurement of neurological and neuropsychological impairment and disability in multiple sclerosis is challenging. We report a new test, the Multiple Sclerosis Performance Test (MSPT), which represents a new approach to quantifying MS related disability. The MSPT takes advantage of advances in computer technology, information technology, biomechanics, and clinical measurement science. The resulting MSPT represents a computer-based platform for precise, valid measurement of MS severity.

In a nutshell, The Cleveland Clinic has developed a series of tests that measure a variety of factors identified with Multiple Sclerosis. The data is gathered on an iPad:

The MSPT application uses the iPad as a data collection platform to assess balance, walking speed, manual dexterity, visual function, and cognition. The MSPT can be performed in a clinical setting, or by the MS patient themself in a home setting. Data can be transmitted from a distance and entered directly into a clinical or research database, potentially obviating the need for a clinic visit.

This is a vision of the future. The iPad gives patients the ability to do a home assessment and send that data to the clinic remotely. Less visits is less stress on the patient, less crowding at the clinic, cost savings for everyone, and more precise diagnostic data.
