2. Informació de seguretat
Always consult with a healthcare professional before using any knee brace, especially if you have pre-existing medical conditions or are recovering from an injury. Discontinue use and consult a physician if you experience increased pain, numbness, skin irritation, or any adverse reactions while wearing the brace. Do not overtighten the straps, as this may restrict circulation.
3. Sizing and Fit
Accurate measurement is crucial for optimal fit and performance of your knee brace. Follow these steps to determine your correct size:
- Stand with your legs shoulder-width apart, slightly bent, and leg muscles contracted.
- Measure the circumference of your leg at the midpoint of your kneecap.
- Measure 6 inches (15.24 cm) up from the center of your kneecap. At this 6-inch mark, measure the circumference of your thigh.
- Measure 6 inches (15.24 cm) down from the center of your kneecap. At this 6-inch mark, measure the circumference of your calf.
