Iron waist plate is a medical instrument for treating lumbar muscle strain and lumbar disc herniation, which is usually composed of iron plate and rubber band. Its service life is generally about 5 years, and the specific use time is related to the frequency and method of use.
After being used for more than 5 years, the inner rubber band may age, weaken its elasticity, and fail to play a sufficient role in support and protection, resulting in a decline in the therapeutic effect. In addition, if the use method is incorrect or overused for a long time, the service life of iron waist plate may also be shortened.
