Symptoms include gradually worsening muscle loss and weakness. Unlike the other muscular dystrophies, the muscle weakness is accompanied by myotonia (delayed relaxation of muscles after contraction) and by various other non-muscular symptoms. Myotonia produces a specific pattern on an EMG test, which is a range in the frequency of muscle contraction (how fast the muscles contract) between 20 and 80 Hertz and a variation of the amplitude (the size of the muscle contractions).
