Walking speed effects on the lower limb electromyographic variability of healthy children aged 7–16 years
The evaluation of surface electromyography (sEMG) is commonly performed in children with
cerebral palsy (CP) and reliable interpretation necessitates knowledge of the variability in
age-matched, typically developing (TD) children. Variance ratio was calculated for inter-trial
sEMG linear envelope (LE) and the Instantaneous Mean Frequency (IMNF) variability in the
lower limb muscle in TD children, in three different age groups during slow, comfortable
speed, and fast walking. Significantly greater variability was found in the 7–9 group …
