PHYSICAL REHABILITATION FOR ARTHRITIC PATIENTS
Osteoarthritis is the most common cause of chronic pain in dogs, affecting about 20% of the canine population, or 10 to 12
million dogs in the United States.56,57 Sadly, more than half of these animals go untreated. Management of osteoarthritis must be viewed as a lifelong commitment.
NSAIDs, used consistently, have markedly decreased the degree of discomfort associated with this debilitating disease.6,58-61 Drug therapy is the cornerstone of pain control. Because of the chronic nature of the disease, however, other interventions
such as slow-acting disease-modifying agents, weight reduction, modified exercise programs, and physical rehabilitation should
be incorporated into the treatment plan.4,62,63 You can think of the pharmaceutical therapy as an adjunct and a means by which a patient can undergo physical rehabilitation
to ultimately reduce the amount and frequency of medication needed to maintain a comfortable lifestyle. NSAIDs alone can provide
pain relief, but by themselves, they do not directly increase range of motion, muscle mass, or improve synovial fluid production
and turnover. Improvements in these factors can be met through exercise and physical rehabilitation.
Keep in mind that older animals are often afflicted with other systemic conditions that may limit the amount or duration of
medications they can tolerate.64-68 These patients require a thorough medical workup, including a complete blood count and serum chemistry profile and complete
radiographic, physical, neurologic, and orthopedic examinations. Concurrent medical conditions must be treated to ensure the
optimal benefits from physical rehabilitation.
Surgical options to treat, prevent, or delay the onset of osteoarthritis include stifle stabilization for cranial cruciate
ligament rupture, surgery to correct patellar luxation surgery, triple pelvic osteotomy, joint arthrodesis, femoral head and
neck ostectomy, and removal of a fragmented coronoid process, ununited anconeal process, or osteochondritis dissecans lesion.
Physical rehabilitation modalities that often benefit arthritic patients include aquatic exercises; ground treadmill exercise;
walking on level, incline, and decline surfaces; jogging; neuromuscular electrical stimulation (NMES); and therapeutic ultrasound;
as well as massage and other modalities.
A wealth of information exists regarding physical rehabilitation in people, and more information is becoming available regarding
its application in small-animal patients. It is important to be well-versed in the various modalities, the benefits associated
with each and their indications and contraindications. Tailor rehabilitation programs to the individual because the severity
of the condition varies in each patient. Many of the major cities in the United States have physical rehabilitation centers
for pets. These facilities work closely with referring veterinarians to design and implement programs appropriate for each
patient and its condition. It is not difficult to develop a rehabilitation program as a new service within a clinic or hospital.
Therapeutic exercises require little financial investment and equipment. Like all disciplines in medicine and surgery, it
is important to have proper training before beginning a rehabilitation program.
