Grimace scales are used in non-verbal humans, such as babies, to assess severity of pain and assess efficacy of analgesics. Grimace scales have also been developed in some animals, including rabbits, rats and mice.
A couple of things to remember when using the grimace scales:
– It is important that patients are assessed when awake.
– The ear shape and position are a bit tricky to assess in lop-eared rabbits, which many pet rabbits are!
