AB -  TECHNICAL NOTE A FOOTREST-LEG EXERCISE DEVICE FOR LONG-TERM RESTRAINT STUDIES WITH PRIMATES1 A recent study (Braun, Farrer, Zappini, and Crook, 1966) required six monkeys (Macaca mulatta) to be restrained continuously in modified, pillory-neckplate restraint chairs (inset Fig. 1, over page) for 30 consecutive days. Throughout the study, the animal had to be prevented from lifting its buttocks and thighs from shock bars that formed the seat of each chair. In studies involving long-term restraint, such restriction is not typically maintained; from time to time an animal can sit on its haunches, turn around 360 degrees or assume a number of different resting positions. The added restriction of a single seating position had several adverse effects on the subjects during a 30-day trial before the actual study. During the trial, all six monkeys developed edema and psoriasis of the feet and legs, and decubital ulcers in and around their ischial callosities. They were unable to walk for almost an hour after being removed from the chairs. No decrements in operant behavior were observed, but it appeared that further restraint could cause more serious physical debilitation and possibly confound the interpretation of data collected during the actual study.
