[Purpose] The purpose of the current study was to investigate the effects of home exercise involving mild to moderate ratings of perceived exertion and outpatient rehabilitation on the physical performance of a patient with sub-acute dermatomyositis. [Participants and Methods] The subject was a female in her 50s (time since disease onset: 89 days) with a creatine phosphokinase value of 43 IU/L when outpatient rehabilitation began. The patient performed outpatient rehabilitation, 40–80 minutes per session, 1–2 times per week, and home exercise 5–6 times per week. The home exercise load had a modified Borg scale score of 2–4, corresponding to mild to moderate ratings of perceived exertion. [Results] Skeletal muscle mass index, muscle strength of the knee extensors, the five times sit-to-stand test, and maximum walking speed were all improved by the intervention. [Conclusion] Home exercise involving mild to moderate ratings of perceived exertion and outpatient rehabilitation may improve physical performance in sub-acute dermatomyositis.
