Hypertonia: The Stealthy Killer You Can’t See—Here’s Why When it comes to neurological conditions, many remain hidden from plain sight. One such condition is hypertonia—a silent yet potentially serious movement disorder characterized by increased muscle tone. Often overlooked or misdiagnosed, hypertonia can slowly disrupt mobility, balance, and quality of life. Understanding what hypertonia truly is—and why it’s often called the “stealthy killer you can’t see”—is essential for early detection and effective management. ### What Is Hypertonia? Hypertonia refers to abnormally stiff or tight muscles, reducing flexibility and affecting how joints move. While muscle stiffness is a hallmark trait, hypertonia isn’t just muscle rigidity; it disrupts the delicate balance of muscle control, impacting both voluntary movements and posture. Unlike observable ailments, hypertonia may go unnoticed until it significantly interferes with daily activities.
