Effect of Ultrasound Therapy on the Adult-Onset Still’s Disease: A Case Study

Adult Onset Still’s Disease (AOSD) is a rare systemic inflammatory disease of unrecognized etiology and pathogenesis that presents in 5% to 10% of patients as Fever of Unknown Origin (FUO) accompanied by systemic manifestations. We reported a compelling case of a 39-year-old African male who presented with a one-month duration FUO along with skin rash, sore throat, and arthralgia. After an extensive workup, potential differential diagnoses were ruled out, and the patient was diagnosed with AOSD based on the Yamaguchi criteria.After the application of Ultrasound (US) and exercises on both ankles as well as left knee, left elbow, and left wrist, there was an improvement of Visual Analogue Scale by 66.6%, Five Repetition Sit to Stand Test (FRSTS) improved 50%, Timed Up and Go (TUG) test improved 87.5%, and there was also an improvement in the 36-Item Short Form Survey (SF-36), and muscle testing. This result was due to the anti-inflammatory effect of the US, leading to decrease pain and improve function in the individuals.
