OBJECTIVE: To investigate intrinsic viscoelastic changes using shear wave velocities (SWVs) of @entity3500 muscles in @entity1 with early @entity1566 ( @entity1566 ) via acoustic radiation force impulse (ARFI) imaging and to evaluate correlation between the SWV values and @entity508 . METHODS: Eighteen @entity1 with @entity1566 within 3 months and 10 healthy adults participated. We applied the ARFI technique to measure SWV of gastrocnemius muscle (GCM) and long head of biceps femoris muscle. Spasticity of ankle and knee joint was assessed by original Ashworth Scale. RESULTS: Ten @entity1 with @entity1566 had @entity508 . @entity1 with @entity508 had significantly faster SWV for GCM and biceps femoris muscle than those without @entity508 (Mann-Whitney U test, p=0.007 and p=0.008) and normal control (p=0.011 and p=0.037, respectively). The SWV values of GCM correlated with the ankle @entity508 (Spearman rank teat, p=0.026). There was significant correlation between the SWV values for long head of biceps femoris muscle and knee @entity508 (Spearman rank teat, p=0.022). CONCLUSION: ARFI demonstrated a difference in muscle stiffness in the GCM between @entity1 with @entity1566 and those without @entity508 . This finding suggested that stiffness of muscles increased in @entity1566 @entity1 . ARFI imaging is a valuable tool for noninvasive assessment of the stiffness of the spastic muscle and has the potential to identify pathomechanical changes of the tissue associated with @entity1566 .
