### Correlations between Myotonometric Parameters and Patients' Characteristics  
Table 12 includes the correlations between myotonometric parameters (pre drug administration) and patients' characteristics. The relationship between frequency and functional status shows a significant correlation; the more the frequency increases (muscular tension state), the better the functional status. There are also significant correlations between decrement and age of disease onset, and between decrement and functional status. The higher the decrement (elasticity), the lower the age of onset and the better the functional status.
