“…Our observations of significant age effects in individuals with cLBP seem to contrast those of recent research examining MF-SEMG fatigue of the back extensors (da Silva et al 2015). The findings of this previous study did not observe any age-specific effects, neither in healthy volunteers nor in cLBP individuals, although significantly steeper MF-SEMG slopes were observed in cLBP participants as compared to healthy controls.…”

“…When using this spectral SEMG method, clearly less back muscle fatigue was observed in older as compared to younger healthy individuals (Kienbacher et al 2014a). In addition, when using the spectral SEMG method, more back or gluteal muscle fatigue was observed in persons with cLBP as compared to healthy individuals (da Silva et al 2015;Kankaanpaa et al 1998b;Lariviere et al 2003;Roy et al 1989;Roy et al 1990;Sung et al 2009). The MF-SEMG method was also able to discriminate between cLBP patients who were kinesiophobic fear avoiders, as classified by more muscle fatigue, and endurers, as classified by less muscle fatigue (Biedermann et al 1991;Lariviere et al 2010).…”

“…Decline in the MF is also observed in the study of Da Silva et al 25 in muscles of the lumbar region, when the authors sought to compare the parameters of fatigue in young and older people with chronic low back pain. Larivière et al 40 showed the same change on the MF in the gluteus maximus muscle when they analyzed the specificity of an exercise about the "Roman Chair" in healthy people or people with low back pain.…”

“…Median frequency (MF) is the most reliable parameter for measuring the changes of EMG spectra, since this parameter is less sensitive to noises and more sensitive to physiological changes related to muscular fatigue such as the accumulation of lactate and extracellular potassium. This metabolic accumulation leads to reduction in the conduction velocity of the action potential, resulting in a decline in the MF values as the muscle becomes fatigued [23][24][25] . Studies demonstrate the difficulty in assessing the EMG of the forearm muscles due to proximity of the extensor and flexor compartments 26,27 .…”

“…Além disso, os Testes Físicos Funcionais (TFF) também podem fornecer parâmetros sobre estabilidade lombo-pélvica, já que indivíduos com dor lombar tendem a apresentar comprometimento na capacidade física e funcional. Algumas dessas alterações são: hipotrofia muscular, menor resistência e força muscular [10][11][12] , déficit proprioceptivo 13 , alterações de extensibilidade muscular e no controle motor 10,14 . Para avaliar a capacidade físico-funcional da região lombo--pélvica, diferentes testes podem ser encontrados na literatura [15][16][17] .…”
