Abstract

This study aimed to evaluate the effects of Whole-body Vibration (WBV) in dogs with hip dysplasia. Ten dogs with hip dysplasia were submitted to 48 sessions of WBV for a period of 16 weeks. The muscles of the hind limbs were evaluated using measurement of thigh circumference, muscle ultrasound and surface electromyography. Lameness and clinical signs of pain were assessed by visual lameness scoring and owner-based questionnaire, respectively. Kinetic analysis was performed by using a pressure-sensitive walkway. Thigh circumference measurements of both hind limbs and ultrasound measurements of the left hind limb glutei muscles and both right and left quadriceps femoris muscles showed a significant increase. Surface electromyography scores of the vastus lateralis muscle and results of pain questionnaires were close to normal patterns after 48 WBV sessions. On the other hand, no significant differences were observed in visual lameness scoring and kinetic analysis. In conclusion, the use of long term WBV caused improvement of muscle atrophy of the hind limbs and the pain signs in dogs with hip dysplasia, even though alterations in percentage of body weight distribution and lameness signs were not observed.
