A method for recording tendon strain in sheep during locomotion

Strain change in the lateral digital extensor tendon of sheep was measured during locomotion by means of a small metal strain gauge transducer. The strain pattern was correlated with the activity of the muscle and the position of the limb. The main period of tendon strain occurred immediately following a phase of muscle activity as the foot was placed on the ground. A second period of tendon tension occurred as the foot was lifted from the ground. This was again usually associated with a muscular contraction. Daily recordings were taken from 14 animals for about 10 days after implantation of the transducer.
