Effect of passive stretching on the range of motion of osteoarthritic joints in 10 labrador retrievers

Ten labrador retrievers and their owners undertook a programme to determine the effect of passive stretching on the dogs' osteoarthritic joints, which had a restricted range of motion. The range of motion of the joints was measured before and after the 21-day study, during which the owners performed 10 passive stretches for a hold of 10 seconds twice daily. Goniometric measurements showed that the passive stretching had significantly increased the range of motion of the joints.
