CCAT - Certified Companion Animal Rehabilitation Therapist Manual Therapy Techniques Questions and Answers — Questions and Answers
Question 1: A canine patient presents with significant fascial restrictions and adhered skin in the thoracolumbar region, limiting spinal flexibility. Which manual therapy technique is specifically designed to lift and separate the skin and superficial fascia from the underlying muscle?
- Cross-fiber friction
- Skin rolling (Correct answer)
- Grade IV mobilization
- Effleurage
Correct answer: Skin rolling
Skin rolling is a myofascial release technique where the skin is gently lifted and rolled between the fingers and thumbs. This action specifically targets adhesions between the skin, superficial fascia, and deeper tissues, making it the most appropriate choice for this presentation.
Question 2: According to the Maitland grading system for joint mobilization, what is the primary therapeutic goal of performing a Grade III mobilization?
- To increase joint mobility and stretch into tissue resistance (Correct answer)
- To modulate pain with small amplitude oscillations at the beginning of the range
- To perform a high-velocity, low-amplitude thrust at the end of range
- To reduce pain with large amplitude oscillations within the pain-free range
Correct answer: To increase joint mobility and stretch into tissue resistance
A Grade III mobilization is characterized by large-amplitude oscillations that are performed up to and into the limit of the available range of motion. Its primary purpose is to stretch the joint capsule and surrounding tissues to increase mobility.
Question 3: Which of the following patient conditions represents a systemic contraindication for the application of a vigorous, full-body therapeutic massage?
- Chronic osteoarthritis
- Compensatory muscle soreness
- Fever (Correct answer)
- Mild muscle strain (7+ days post-injury)
Correct answer: Fever
A fever indicates a systemic infection or illness. Vigorous massage increases circulation throughout the body, which could potentially spread the infection and worsen the patient's condition. Therefore, it is a systemic contraindication.
Question 4: To achieve a plastic, long-lasting change in the length of a chronically contracted muscle-tendon unit in a geriatric dog, which stretching principle is most effective?
- Multiple high-velocity, short-duration stretches
- A single, maximum-force stretch held for 10 seconds
- Ballistic bouncing movements at the end of the range of motion
- A low-load, prolonged stretch held for several minutes (Correct answer)
Correct answer: A low-load, prolonged stretch held for several minutes
A low-load, prolonged stretch (LLPS) applies a gentle but sustained force to connective tissues, allowing for a phenomenon called "creep," where the tissue gradually elongates. This leads to plastic deformation and a more permanent increase in length, which is safer and more effective for chronic contractures than brief, high-force methods.
Question 5: The manual therapy technique of petrissage, which involves kneading, squeezing, and lifting the soft tissues, is primarily used to achieve which physiological effect?
- Introduce therapeutic touch and warm the superficial tissues
- Calm irritated nerve endings with light, gliding strokes
- Increase circulation and reduce adhesions in deeper muscle tissue (Correct answer)
- Stimulate muscle spindles via rapid, percussive movements
Correct answer: Increase circulation and reduce adhesions in deeper muscle tissue
Petrissage is a technique that mechanically works on deeper muscle layers. The kneading and lifting actions help to increase local blood flow, reduce muscle tension, and break down adhesions or "knots" within the muscle and fascia.
Question 6: When treating a myofascial trigger point in a dog's infraspinatus muscle using ischemic compression, what is the correct application of the technique?
- Applying deep, circular friction over the trigger point for 2 minutes
- Holding sustained, direct pressure on the point until a release or softening is felt (Correct answer)
- Using a vibration tool to rapidly stimulate the trigger point
- Stretching the muscle to its maximum length before applying pressure
Correct answer: Holding sustained, direct pressure on the point until a release or softening is felt
Ischemic compression involves applying sustained, direct pressure to a trigger point. This pressure temporarily restricts blood flow (ischemia), and upon release, a reactive hyperemia occurs. The sustained pressure itself is thought to disrupt the dysfunctional feedback loop within the trigger point, leading to its release.
