Abstract EN
Age-related neuromuscular change of Tibialis Anterior (TA) is a leading cause of muscle strength decline among the elderly.
This study has established the baseline for age-associated changes in sEMG of TA at different levels of voluntary contraction.
We have investigated the use of Gaussianity and maximal power of the power spectral density (PSD) as suitable features to identify age-associated changes in the surface electromyogram (sEMG).
Eighteen younger (20–30 years) and 18 older (60–85 years) cohorts completed two trials of isometric dorsiflexion at four different force levels between 10% and 50% of the maximal voluntary contraction.
Gaussianity and maximal power of the PSD of sEMG were determined.
Results show a significant increase in sEMG’s maximal power of the PSD and Gaussianity with increase in force for both cohorts.
It was also observed that older cohorts had higher maximal power of the PSD and lower Gaussianity.
These age-related differences observed in the PSD and Gaussianity could be due to motor unit remodelling.
This can be useful for noninvasive tracking of age-associated neuromuscular changes.
