Pisa syndrome (PS) refers to marked lateral flexion of the trunk with a Cobb angle greater than 10°, which is typically mobile and can be resolved by lying down. PS is one of the most common postural deformities secondary to Parkinson's disease (PD) and can aggravate scoliosis in the advanced stages of PD.Here, we present the case of a 53-year-old woman who presented with lateral curvature for 6 mo. Full spine X-ray films in the correct position showed that the thoracolumbar spine was bent to the right without any rotation of the vertebrae. The patient was diagnosed with Pisa syndrome. After receiving a month's treatment with electroacupuncture, the Cobb angle decreased from 18.14° to 13.41°.This case demonstrates that electroacupuncture can effectively improve Pisa syndrome secondary to PD with few side effects and a low risk of recurrence. Additionally, early accurate diagnosis and timely intervention are meaningful for the prognosis of PS.©The Author(s) 2022. Published by Baishideng Publishing Group Inc. All rights reserved.
