Mobile arm supports: an evaluation.

The results of a follow-up survey of 124 patients fitted with mobile arm supports at Mary Marlborough Lodge between 1970 and 1976 are presented. Of the patients fitted with mobile arm supports 33% are known to have used them for over one year, and 47% of those who were contacted were still using them. The reasons for non-use and the implications of the necessity for readjustments are discussed.
