Description
Summary:Inversion tables are used as treatment for back pain, but there is a lack of agreement on systemic effects of inversion. To assess intracranial pressure (ICP) and cerebral blood flow using ultrasonography during inversion table tilt. Optic nerve sheath diameter (ONSD), heart rate (HR), blood pressure, internal carotid artery (ICA) and middle cerebral artery (MCA) blood flow of participants were measured in 3 positions: supine before inversion, during inversion with head down, and supine post-inversion. ONSD was evaluated with ocular ultrasonography and blood flow (ICA and MCA) with Doppler ultrasonography. The ONSD changed significantly between the supine position, at 3 min of inversion, and after returning to supine position (all P
