About

Antonio Suppa is a leading movement disorders researcher whose work centers on the pathophysiology and quantitative assessment of Parkinson’s disease (PD), with a particular focus on rigidity and balance impairment. His major contributions include pioneering the use of biomechanical and neurophysiological measures to objectively characterize parkinsonian rigidity, demonstrating its velocity-dependent nature and the effects of levodopa treatment. His 2023 study on rigidity in PD, which has garnered 31 citations, established critical methodological frameworks for instrumental measurement of this cardinal motor sign. Suppa’s research on early balance impairment using robot-assisted axial rotations (2021, 28 citations) has advanced understanding of postural instability in PD. His recent work (2025) on cogwheel rigidity provides novel clinical, biomechanical, and neurophysiological insights into this poorly understood phenomenon. Through his innovative integration of robotics and neurophysiology, Suppa has significantly advanced the objective quantification of motor symptoms in Parkinson’s disease, offering both diagnostic and therapeutic implications. His research continues to shape how clinicians and scientists approach the measurement and treatment of rigidity and balance disorders in PD.
