Understand the physiology behind heat and cold therapy in physical therapy — when to use each modality, how they work, and what the science says about their effects on healing. “Should I put ice or heat on it?” It is one of the most common questions physical therapists receive. The answer, according to modern physiology…
Understand the three phases of tissue healing — inflammation, proliferation, and remodeling — and how physical therapy supports each stage of the regenerative process. The human body’s capacity to heal itself is one of nature’s most remarkable achievements. A broken bone rebuilds itself to near-original strength. A torn tendon gradually restores tensile capacity. A skin…
Learn how platelets and the coagulation cascade stop bleeding, initiate healing, and how platelet biology informs physical therapy and PRP treatments. Every injury that breaks blood vessels — from a minor skin abrasion to a surgical incision, from a muscle tear to a fractured bone — must be met with an immediate response: stop the…
Learn about the different types of white blood cells, how they defend the body against injury and infection, and how physical therapy influences immune cell activity. When an injury occurs — a torn muscle, a sprained ligament, a post-surgical wound — the body’s healing process depends on a rapid mobilization of the immune system. At…
Understand the biology of inflammation — why it is necessary for healing, when it becomes problematic, and how physical therapy manages inflammation for optimal recovery. Few biological processes are as misunderstood as inflammation. Popular culture treats it as an enemy — something to be suppressed with ice packs, anti-inflammatory drugs, and rest at all costs….
Learn how the immune system responds to injury, how it coordinates the healing process, and how physical therapy supports immune function during rehabilitation. When you sprain an ankle, tear a muscle, or undergo surgery, your body faces a dual challenge: repair the damaged tissue and defend against potential infection. Both tasks fall to the immune…
