Purpose: The purpose of the study was to investigate the use of real time elastography in evaluating the muscle stiffness comparing to Ashworth scale. The aim of the study is to create an elastography score for MS patients.

Methods and Materials: We investigated 101 MS patients, 61 women and 40 men. Disability score assessed by Expanded Disability Status Score of Kurtzke scale ranged from 0 and 8.5 with a mean value of 3.5. In all patients a neurological examination was performed and referred to Ashworth scale score by a neurologist. All patients underwent real time elastography on Esaote my Lab Twice with transducer with a high frequency probe 4-13 MHz. The muscles examined were quadriceps of both legs. The study was a double-blinded one, and it was approved by local Ethic Committee.

Results: There was full concordance between the Ashworth scale evaluation and elastography score. However, patients classified as score 0 in the Ashworth scale can be spitted in 0a (total normality of muscle fibers elasticity) and 0b (initial compromising of muscle fibers elasticity). The main result of the study was the creation of an elastography score of muscle stiffness in MS patients that can be compared with Ashworth scale.

Conclusion: Ashworth scale is at present the only method to evaluate muscle stiffness in MS patients. Our study demonstrated for the first time that it is possible to have an imaging method to assess this clinical examination giving new possibilities to follow the evolving of the disease in these patients.
