A flexible restraint chair for the cynomolgus monkey (Macaca fascicularis) (1982)

Nakamura, R. K., Coates, R., Crawford, H. et al.

Abstract

There is a general consensus that restraint chairs should be used only where necessary, since they inherently cause monkeys physical and emotional stress. Authors found that the animals showed restless sleeping patterns which persisted despite our attempts to adapt the animals to the chairs slowly. It was soon evident that the restlessness resulted from the rapid development of chafing at the neck, a breakdown of tissue in the ischial pads, and lesions at the base of the tail.
