“…Significant shear strains were also recorded. Lanyon & Smith (1970) measured peak axial tensile strains during gait of approximately t0.0007 on the cranial aspect of sheep radii and peak compressive strains of 4 . 0 0 1 2 on the caudal aspect.…”

“…strain) during locomotion of animals and humans can be accurately assessed using strain gages [1][2][3]. There are detailed descriptions of the packaging and implantation of both sin gle and rosette strain gages for application in a range of dif ferent animals [2,4], The first report of strain gage analysis in horses described bonding single-element strain gages onto different bones in an acute experiment [5], Unlike the single-element gages, rosette strain gages allow the angle and direction of the principal strains to be determined.…”

Stacked rectangular rosette strain gages were used to measure surface bone strain on the dorsomedial cortex of the third metacarpal bones in 6 adult Thoroughbred horses during treadmill exercise. The peak principal compressive and tensile strains, angle of the peak strains and strain rate during loading were calculated and compared with speed and gait. At speeds from 4 to 14 m/s loading on the metacarpus resulted in compression of the dorsomedial cortex. Tension only occurred consistently in 1 forelimb of 1 horse at the walk (2 m/s). The angle of peak compression was within 10° of the longitudinal axis of the bone, and the magnitude of compression was proportional to the speed of exercise. Mean maximum compressive strains in the 6 horses at 2 m/s were –668 µstrain, –1,204 µstrain at 4 m/s; –1,617 µstrain at 6 m/s; –2,127 µstrain at 8 m/s, and –2,533 µstrain at 10 m/s. Recordings from 3 horses gave a mean –3,206 µstrain at 12 m/s, and strains at 14 m/s approached –4,000 µstrain. Peak strains were similar in both forelimbs at the canter while strain rate tended to be higher in the leading forelimb.

“…, 1979a, In con trast, stress analyses based on in vivo bone strain data have the advantage that many of these assumptions can be avoided. For example, over the past 10 years consid erable progress has been made towards gaining an understanding of patterns of internal stress in bone by characterizing in vivo surface bone strain patterns for a wide variety of bones in several different species during activities such as eating and drinking, walking and run ning, and breathing [Lanyon and Smith, 1970;Lanyon, 1971Lanyon, , 1973Lanyon, , 1974Cochran, 1972;Barnes and Binder, 1974;Hylander, 1977Hylander, , 1979aLanyon et al, 1975;Lanyon and Bourn, 1979;Carteret, al., 1980]. The purpose of this study is to characterize patterns of in vivo tibial bone strain using strain gauges bonded to dog tibiae.…”

Rosette and single-element strain gauges were implanted on the tibia in 2 dogs and recordings were made during locomotion on a treadmill. At foot contact and during the swing phase of locomotion, bone strains were low and directions of the principal strains were variable. There was a large shift in the directions of the principal strains at the beginning of the stance phase and bone strains were considerably higher. Peak strain occurred midway through the stance phase. At that time, the maximum pπnicipal strain (tension) was directed upwards and anteriorly between 30 and 60° with respect to the long axis of the tibia. These bone strain patterns in the dog are similar to those found in sheep while both differ markedly from those found in humans.
