Which of the following is a common modality used in physical therapy?

Heat therapy is a common modality used in physical therapy because it helps to relax muscles, improve circulation, and reduce stiffness in soft tissues. It is often employed in treatment plans to alleviate pain and prepare tissues for rehabilitation exercises. Heat can be applied using various methods, including hot packs, infrared heating pads, or whirlpool baths, each aiding in the recovery process by enhancing blood flow, which brings essential nutrients to the affected area while also promoting healing.

While ultrasound therapy and massage therapy are indeed common modalities in physical therapy, heat therapy specifically offers unique benefits that align with the specific goals of physical rehabilitation. Chiropractic therapy, on the other hand, is more focused on the diagnosis and treatment of musculoskeletal issues through manipulation and adjustment, rather than being strictly categorized as a physical therapy modality.
