چکیده مقاله:
Background: As people get older, muscles become more synchronized and cooperate to accomplish
an activity, so the main purpose of this research is to determine the relationship between changes in
age and the amount of muscle synergy. The presence of muscle synergies has been long considered
in the movement control as a mechanism for reducing the degree of freedom of the motor system.
Methods: By combining these synergies, a wide range of complex movements can be produced.
Muscle synergies are often extracted from the electromyogram (EMG) signal. One of the most
common methods for extracting synergies is the nonnegative matrix factorization. In this research,
the EMG signal is obtained from individuals from different age groups (namely ۱۵–۲۰ years, ۲۵–۳۰
years, and ۳۵–۴۰ years), and after preprocessing, the muscular synergies are extracted. By processing
and studying these synergies. Results: It was observed that there is a significant difference between
the muscular synergy of different age groups. Furthermore, there was a significant difference in the
mean value of synergy coefficients in each group, especially in motions that were accompanied
by force. Conclusion: This result candidates this parameter as a biomarker to differentiate and
recognize the effects of age on the individual’s muscular signal. In the best case, using the synergy
tool, classification of the age of persons can be done by ۷۷%.
