Superbly designed with its super-size stainless steel base, this scale is ideal to weigh anything from cats to large dogs up to 150kg. 2 A delay or inability to correct the paw indicates a nonspecific neurologic deficit. Neck flexion is usually not performed postoperatively or if an atlantoaxial subluxation (instability between C1 and C2) or fracture is suspected (Figures 15 and 16). Source: Platt SR, Radaelli ST, McDonnell JJ. Mentation changes caused by systemic metabolic disorders should improve markedly as the systemic abnormalities are corrected unless secondary damage has occurred.

It also initiates and controls voluntary movement and is critical for learning, behavior, and memory. Owing to the inability to contract the muscles in the pelvic limbs, regardless of diagnosis, this patient should be protected from developing decubital ulcers with thick bedding, padding around bony prominences, and frequent rotation of position.

To improve circulation and maintain joint health, massage of the affected limbs and passive range of motion of all affected joints should be performed while the patient is recovering. Proprioceptive receptors are present in muscles, joints, and tendons throughout the body, and they relay proprioceptive information to the forebrain to adjust posture or limb position.3 As such, testing proprioception is a simple but important way to generally evaluate the nervous system.2.

Read. A wide-based stance (FIGURE3), swaying, or leaning on objects for support indicates vestibular system or cerebellar dysfunction.5 Continuous or intermittent tremors or other uncontrolled movements are nonspecific observations indicating neurologic abnormalities that can arise from many potential causes.5.
