I’ve just found a video that has footage of the ‘Lazarus sign‘ – a complex reflex movement that can occur in brain dead patients where the arms are raised to the chest and often fall crossed onto the body.

We’ve covered this reflex before, noting that despite its complexity it is generated by the spine, which is why it can still appear after brain death.

However, I didn’t realise there a video of it was available online where you can see the unnerving post-mortem movement triggered by doctors as they move the head.

If you’re uncomfortable about seeing dead bodies this isn’t the video for you, particularly as it shows what seems to be quite a young lad who presumably just very recently passed away.

It’s titled and narrated in Portuguese by (I’m guessing) a Brazilian medical team to demonstrate the reflex.

I noticed there’s also a video with a sequence of stills of the Lazarus sign in English which also explains the concept of a spinal reflex arc, although you’ll need to login to YouTube to see it.
