Pathophysiology of entrapment neuropathies

This blog summarises the available evidence on the influence of entrapment neuropathies on the anatomical and physiological features of the peripheral nervous system that have previously been discussed. Let’s get started! Entrapment Neuropathies and Ischaemia Entrapment neuropathies are hypothesised to disrupt intraneural blood flow by reversing the pressure gradient required for optimal blood supply. Extraneural pressures as low as 20–30 mmHg interrupt intraneural venous circulation, … Continue reading Pathophysiology of entrapment neuropathies

Spinal manipulation and mobilization in the right direction: part 2

Finding the best way to manipulate or mobilize the spine in patients with severe radiculopathies can be difficult for many physiotherapists. There are two ways to determine the right direction. The first is the H-reflex approach, which Mohamed Sabahhi described (Abdulwahab and Sabbahi, 2000; Ali Ashraf and Sabbahi, 2001; Ali and Sabbahi, 2000), Another one is the Robin McKenzie-described pre-manipulative testing (McKenzie R 1981). Both … Continue reading Spinal manipulation and mobilization in the right direction: part 2

Lhermitte’s Sign

Purpose of Lhermitte’s Sign: To determine if there is a dural or meningeal irritation in the spine or to check if the dorsal column of the spinal cord is hyperexcitable due to demyelination. Patient position: Long sitting. Examiner position: Standing beside the examining table while the patient is in a long sitting position. Procedure: The examiner performs a gentle, passive flexion of the patient’s neck … Continue reading Lhermitte’s Sign
