I've been an inpatient psychiatric nurse for 23 years. I use hospital restraints on a daily basis and this looks to absolutely be either wrist/waist restraints with the waist portion dangling or 4 point restraints with the portion that goes beneath the mattress dangling. Is there an inpatient psych hospital nearby? (Although, if an escape occurred, I'm sure LE would know who this lady is.) Almost without fail, if a patient is in such a state to be restrained for the protection of themselves and others, they are moderately medicated. She appears to be distressed and drugged at the same time.
