Continuous Shortwave Diathermy (CSWD) is used to accomplish which of the following?

• A. Increase extensibility of deep collagen tissue
• B. Decrease elasticity of soft tissues
• C. Reduce blood flow to the area
• D. Delay healing in the postacute stage

Answer: (A)

Continuous Shortwave Diathermy works by heating deep tissues, especially collagen-rich structures like fascia, tendons, and ligaments. When collagen is heated, it becomes more pliable and its fibers can slide past each other more easily, so the tissue is more extensible. That means joints can be moved through a greater range with less resistance during stretching, which is why increasing the extensibility of deep collagen tissue is the best fit. Heating does not decrease tissue elasticity; it enhances pliability. It also tends to increase blood flow through vasodilation, not reduce it, and it is not used to delay healing—in fact, when applied appropriately, heat can support healing by increasing metabolic activity and blood supply.
