What does 'manual therapy' involve in canine physical rehabilitation?

Manual therapy in canine physical rehabilitation refers specifically to hands-on techniques used by practitioners to alleviate pain and enhance mobility in dogs. This type of therapy includes various methods such as manipulation, mobilization, soft tissue techniques, and massage. The goal is to directly affect the musculoskeletal system, helping to improve blood circulation, reduce muscle tension, and increase range of motion.

The other options, such as therapeutic swimming or electrotherapy applications, while valuable treatments, do not fall under the definition of manual therapy as they do not involve direct hands-on interaction. Similarly, behavior modification training focuses on the psychological and behavioral aspects of the animal, which is unrelated to the physical techniques employed in manual therapy. Therefore, the correct choice accurately captures the essence of manual therapy's role in canine physical rehabilitation.
