Measuring handicap in multiple sclerosis.

Handicap, shortly to be renamed participation, is a well defined though somewhat neglected entity which addresses an important aspect of the impact disease has on the individual. It is particularly relevant in Multiple Sclerosis (MS) which has such a major impact on issues such as employment, relationships, transport and social integration. Few validated measuring tools exist, and the generic London Handicap Scale is probably the best currently available but is only appropriate for group comparison. Handicap should be monitored in MS and is particularly appropriate in the evaluation of rehabilitation strategies.
