The efficacy of 2 sets of collars (Kiltix Collar, Bayer AG), containing different plasticisers and impregnated with the acaricides flumethrin (2.25%) and propoxur (10%), was compared against adult Rhipicephalus sanguineus on experimentally infested, kennelled dogs. Thirty individually penned dogs were infested with 25 male and 25 female, unfed R. sanguineus. On the following day they were alloc...

The analysis of current cervical collars (Aspen and Miami J collars) and cervical thoracic orthoses (CTOs) (Aspen 2-post and Aspen 4-post CTOs) in reducing cervical intervertebral and gross range of motion in flexion and extension was performed using 20 normal volunteer subjects. The gross sagittal motion of the head was measured relative to the horizon with the use of an optoelectronic motion ...

BACKGROUND CONTEXT In the prehospital stages of emergency care, cervical collars are (supposedly) used to aid rescuers in maintaining in-line stabilization of the spinal column as patients with potential or actual injuries are shifted onto a spine board to achieve full spinal immobilization. Unfortunately, not a single study has examined the effectiveness of cervical collars to control motion d...

The cervical collar has been routinely used for trauma patients for more than 30 years and is a hallmark of state-of-the-art prehospital trauma care. However, the existing evidence for this practice is limited: Randomized, controlled trials are largely missing, and there are uncertain effects on mortality, neurological injury, and spinal stability. Even more concerning, there is a growing body ...
