[Rehabilitation for myositis in acute phase].

Polymyositis and dermatomyositis (PM/DM) are representative inflammatory muscle diseases. In treatment of PM/DM, drug therapies are cardinal but rehabilitation may be another option. Since muscles with PM/DM are fragile for muscle exercise, rehabilitation has been recommended mainly in chronic phase. Some researchers considered that rehabilitation for PM/DM patients in acute phase may improve their functional prognosis without major sideeffect. However, there are controversies about rehabilitation for PM/DM patients from acute phase. To consider advisability, I reviewed literatures concerning rehabilitation for PM/DM patients in acute phase.
