I appreciate the illustration and detailed explanation. I wonder patients with C-sections or peripheral nerve-damaged pts show positive signs as well. My two cents- the bass of the audio resonates so much your voice sounds a little robotic and reduces the clarity
Thank you Kate for your comment, will definitely take this on board in subsequent recordings. Regarding your query; agree that a C-section (Pfannenstiel incision) involving the lower abdominal muscle wall would cause an iatrogenic Beevor's sign. Re: peripheral nerve damage, 1 case report mention CIDP causing an inverted Beevor's sign - possibly due to upper thoracic intercostal nerve involvement bmcneurol.biomedcentral.com/articles/10.1186/s12883-021-02287-5. I would guess that length-dependent peripheral neuropathies with motor involvement could cause either Beevor or Inverted Beevor's sign, which may be based on the 'xmas tree' distribution of peripheral nerve fibres supplying the abdomen. Hope this helps.
@@NeurologyAnalogy Thank you for the in-depth reply, that was helpful! Idk how to describe the electronic-like sounds I hear with audio but it was more obvious with headphones.
Great question. Abdominal reflex testing before Beevor's testing is not mandatory, especially as absent abdominal reflexes can be a normal finding in 20% of the population (more in elderly). Because of this Beevor's sign has better localising value than abdo reflex testing. If Beevor's sign is positive, it would be expected that the area around the weak rectus muscles would have reduced reflexes. Hope this helps.
