Normal range of joint mobility in the extremities of the patas monkey, Erythrocebus patas , was established for a free‐ranging colony of 64 animals at La Parguera, Puerto Rico (Caribbean Primate Research Center). Eighty‐five animals that had been caged (30′′ × 30′′ cages) for up to 5 years were used for comparison. Passive joint mobility of anesthetized animals was measured with a goniometer. Nine parameters (five on the forelimb and four on the hindlimb) were measured on each animal. The data were sorted into subsets according to the animal's age, sex, place of birth, and type of confinement, if any. The number of animals in each subset was recorded and the mean (in degrees) and standard deviation for each parameter were calculated. A P⩽0.05 on two‐tailed Student's t‐tests was considered significant. Comparisons between free‐ranging males and females showed significant differences in one or two parameters for all age groups. A cross‐sectional sample of free‐ranging animals of both sexes showed that significant changes in joint mobility occurred only in the first 18 months of life. Joint mobility of all caged animals, however, was highly variable, and even between the more mature animals there were significant differences in several parameters. Almost all comparisons of subsets of the same age and sex showed significant differences between caged and free‐ranging animals in at least one parameter. When the caged animals were laboratory‐born, however, these differences were significant in five out of nine parameters. The results suggest that, although caging itself affects joint mobility, the age of first confinement may have an even greater effect than the length of the confinement
