Objective To investigate the Young's modulus of the biceps brachii and brachioradialis in Parkinson's disease( PD) with quantitative shear-wave ultrasound elasticity technique, and to observe the value of elastography in PD. Methods A shear-wave elasto-sonography(Aixplorer model, Supersonic Imaging, France) coupled with a linear array transducer array(4~15 MHz) was employed. Shear-wave ultrasound elasticity imaging of biceps brachii and brachioradialis longitudinal section were performed in 46 patients with Parkinson's disease〔mean age(47. 9±2. 8) years〕 in both sides and 31 healthy controls〔mean age(46. 7±3. 2) years〕 in right arm. The quantitative elasticity values were compared among the patients' symptomatic side, another side(non/mild symptom) and the controls. Results The Young's modulus of biceps brachii in symptomatic side, another side of patients and controls were(59. 94±20. 91)kPa, (47. 77±24. 00)kPa and(24. 44±5. 09)kPa, the mean elasticity modulu values of the biceps brachii longitudinal section of PD patients were greater in both sides than those of control group(P<0. 05), and the mean value of the biceps brachii in symptomatic side was higher than that of another side(P<0. 05). The mean Young's modulus of biceps brachii in symptomatic side, another side of patients and controls was(32. 18±17. 19)kPa, (28. 41±13. 19) kPa and(21. 71±7. 45) kPa, the mean elasticity modulus of the brachioradialis longitudinal section of PD patients were greater in both sides than those of control group(P<0. 05), but there was no significant difference in the symptomatic side and another side of PD patients(P>0. 05). Conclusion Shear-wave ultrasound elasticity imaging can find the characteristics of the elastic modulus of the biceps brachii and brachioradialis longitudinal section, providing a new method to assess the muscle tone in PD.
