Symptoms include stiffness and sometimes muscle cramping after exercise (pseudo-myotonia) and especially when exposed to cold. The most commonly affected muscles are in the arms, legs, and eyelids. Individuals with Brody myopathy also sometimes experience weakness,

These drugs act by limiting the amount of Ca from being released from the sarcoplasmic reticulum. When a muscle is stimulated, Ca is released from the sarcoplasmic reticulum into the cytoplasm where it binds to a protein called
300:. This event allows the muscle fibers to overlap, causing a contraction. In BD, Ca levels are high in the cytoplasm, which means Ca can readily bind troponin, leading to muscles that are in an extended state of contraction. 439:
