‘护腰’ literally means ‘to protect the waist’ — ‘护’ (hù) means ‘to protect’ or ‘to guard’, and ‘腰’ (yāo) means ‘waist’. Together, they form a compound noun referring to a supportive device worn around the lower back and waist to stabilize the lumbar spine, relieve strain, or aid recovery from injury. It is commonly used in medical, fitness, and occupational contexts.

This term is widely used in daily life — for example, doctors may recommend wearing a 护腰 after back surgery; office workers use it during long hours of sitting; and athletes wear it during heavy lifting or rehabilitation exercises. Unlike general belts, a 护腰 is specifically designed with elastic fabric, rigid stays, or adjustable straps to provide targeted support. It’s not decorative but functional, often made of breathable, compressive materials.
