Abstract
Objective: To compare the mechanical properties of the supraspinatus
tendon in different age groups using Supersonic Shearwave Imaging
(SSI) elastography. Methods: We evaluated 38 healthy individuals of
both genders, 20 being in the range of 20 to 35 years and 18 being
over 60 years. The shear modulus of the supraspinatus tendon was
measured by SSI elastography, always on the right side. Means
between age groups were compared and statistically analyzed
using the Shapiro-Wilk normality test followed by the student’s t-test
and were established as a statistically significant value of p ≤ 0.05.
Results: A statistically significant difference was observed when
the mean values of the shear modulus of the supraspinatus tendon
of young adults (23.98 ± 9.94 KpA) were compared with those of
older adults (17.92 ± 6.17 KpA). Conclusion: We found a difference
between the means of the shear modulus measured by the SSI
elastography, showing a significant decrease of the shear modulus
with the chronological age progression. Level of Evidence III,
