Spa therapy may play an important complementary role in the treatment of jo
int diseases. Spa therapy alleviates suffering and is almost totally devoid
of serious adverse effects. The improvement that is reported in studies of
patients receiving spa therapy is short term, lasting for months. Clinical
trials of alternative therapeutic methods such as spa therapy are justifie
d and should be conducted. To date, no studies have evaluated the cost-effe
ctiveness of spa therapy.
