Facial expressions of pain in cats: the development and validation of a Feline Grimace Scale [PDF]
Scientific Reports, 2019 Grimace scales have been used for pain assessment in different species. This study aimed to develop and validate the Feline Grimace Scale (FGS) to detect naturally-occurring acute pain. Thirty-five client-owned and twenty control cats were video-recorded

Exploring naturally occurring clinical subgroups of post-traumatic headache
The Journal of Headache and Pain, 2020 Objective To explore naturally occurring clinical subgroups of post-traumatic headache. Background Persistent post-traumatic headache (PTH) is defined as a headache developing within 7 days of an injury that lasts for greater than 3 months.

Persistent idiopathic facial pain
Definitions, 2020 Currently, among all types of orofacial pain, the least studied is persistent idiopathic facial pain (PIFP), also known by the old name atypical facial pain.

International Journal of Environmental Research and Public Health, 2020 Trigeminal neuralgia (TN), the most common form of severe facial pain, may be confused with an ill-defined persistent idiopathic facial pain (PIFP). Facial pain is reviewed and a detailed discussion of TN and PIFP is presented.

Facial expression of pain: an evolutionary account. [PDF]
, 2002 This paper proposes that human expression of pain in the presence or absence of caregivers, and the detection of pain by observers, arises from evolved propensities. The function of pain is to demand attention and prioritise escape, recovery, and healing;

The neurobiology of pain and facial movements in rodents: Clinical applications and current research
Frontiers in Veterinary Science, 2022 One of the most controversial aspects of the use of animals in science is the production of pain. Pain is a central ethical concern. The activation of neural pathways involved in the pain response has physiological, endocrine, and behavioral consequences,

Automatic Detection of Pain from Spontaneous Facial Expressions [PDF]
, 2017 This paper presents a new approach for detecting pain in sequences of spontaneous facial expressions. The motivation for this work is to accompany mobile-based self-management of chronic pain as a virtual sensor for tracking patients' expressions in real-
