Goniometric measurement of joint angles in crab-eating foxes (Cerdocyon thous)

Abstract

This study aimed to assess joint angle values in the forelimbs and hind limbs of crab-eating foxes (Cerdocyon thous) using a conventional manual goniometer. Nine captive crab-eating foxes, aged over 1 yr old, weighing from 5.9 to 7.5 kg were used. The maximum flexion and maximum extension of the shoulder, elbow, carpal, hip, stifle, and tarsal joints were measured. The range of motion was determined through the difference between the maximum flexion and the maximum extension. There was no significant difference between the right and left sides in the goniometric measurements. The mean values of the range of motion for shoulder, elbow, carpal, hip, stifle, and tarsal joints were respectively 108°, 99°, 131°, 79°, 103°, and 86°. The goniometric values of the crab-eating foxes can be used as means of comparison with other animals from the same species for diagnostic purposes, research documentation, and evaluation of therapeutic procedures.
