Reevaluation of predictive factors for complete recovery in dogs with nonambulatory tetraparesis secondary to cervical disk herniation.

The vast majority of dogs with cervical disk herniation experience cervical pain and only mild motor deficits; therefore, not much is known about the factors that predict recovery in dogs with nonambulatory tetraparesis (NAT) secondary to cervical disk herniation. In this retrospective study, we tested the hypothesis that two previously reported prognostic factors, site of disk herniation and severity of neurological deficits, are useful predictors of complete recovery. Overall, 20 (62%) of 32 dogs with cervical disk herniation-associated NAT had complete recovery.

Effects of treadmill inclination on electromyographic activity and hind limb kinematics in healthy hounds at a walk.

Objective: To evaluate the effect of treadmill incline on muscle activity and joint range of motion (ROM) in hind limbs of dogs.

Animals: 8 purpose-bred healthy adult hounds.

Procedures: Activities of the hamstring (semimembranosus, semitendinosus, and biceps femoris muscles), gluteal (superficial, middle, and deep gluteal muscles), and quadriceps (femoris, vastus lateralis, vastus intermedius, and vastus medialis muscles) muscle groups and hip and stifle joint ROM were measured with surface electrogoniometric and myographic sensors in hounds walking on a treadmill at 0.

The influence of age on patellar reflex response in the dog.

The patellar tendon reflex is a clinical parameter commonly used to assess neurological status. Factors such as quadriceps muscle fiber composition, femur length, and patient age have been reported to influence total and fractionated reflex times in human beings. The purpose of this blinded, cross-sectional study was to examine the effect of age on the patellar reflex in the dog.
