Which of the following is NOT an effect of PAM?

• A. Reduce tissue inflammation
• B. Accelerate tissue healing
• C. Modify collagen extensibility
• D. Improve cognitive function

Answer: (D)

PAMs primarily influence local tissue processes and the mechanical properties of tissues, not brain function. Reducing tissue inflammation is a common goal of many physical agents because controlling inflammation can limit edema and pain. Accelerating tissue healing is another expected effect, as modalities can enhance blood flow, cellular activity, and tissue repair. Modifying collagen extensibility occurs with heating or certain modalities that increase tissue temperature, temporarily improving viscoelastic properties and allowing greater stretch. Improve cognitive function is not a direct or typical effect of PAMs, since these modalities target local tissues, joints, and nerves rather than brain function. Any cognitive changes would be indirect and not a primary therapeutic outcome of PAM use.
