Scapular Muscle Actions During Lowering of the Arms With Shoulder Impingement Syndrome

Ajustes posturais dos músculos escapulares e globais como mecanismos de controle do movimento do ombro e da postura

“…The results demonstrate that from the 25 articles selected (Table 3, Table 4 and Table 5), in 10 an abnormal muscle activation intensity of the SA was found (Araújo et al 2017;Helgadottir et al 2011;Oliveira et al 2012) (Table 3) and 8 has shown equal muscle activation intensity between patients and controls (Ayatollahia et al, 2016;Bandholm et al 2006;Castelein et al, 2016;Cools et al 2004;Faria et al 2008;Lopes et al 2015;Larsen et al 2013;Roy et al 2008) (Table 4). Among the results, 8 studies found a lower muscle activity of SA during tasks of upper limb between patients and controls (Araújo et al 2017;,…”

“…However, in some cases they do not show a significant difference between patients and controls (Bandholm et al, 2006;Cools et al, 2004;Faria et al, 2008;Lopes et al, 2015;Moraes et al, 2008;Roy et al, 2008;Santos et al, 2007), the controls also had some type of dysfunction or pathology only in asymptomatic way (Moraes et al, 2008;Lopes et al, 2015). The asymptomatic controls may exhibit the same patterns of activation that patients with symptoms, as already exhibit the dysfunction or disease, but compared to normal individuals this intensity pattern of relationship and muscle activation time may be different in SA.…”

“…According to results of the survey data, we have found that in most cases there is a change in muscle activity of the serratus anterior muscle, and abnormality in the muscle activation time or activation intensity (Araújo et al 2017;Bohlooli et al, 2015;Helgadottir et al, 2011;Hio Teng Leong et al, 2017;Oliveira et al, 2012;Padke and Ludewig, 2013;, this result is in agreement with our hypothesis. In contrast, some studies show no change between patients and controls (Ayatollahia et al, 2016;Bandholm et al, 2006;Castelein et al 2016;Cools et al, 2004;Faria et al, 2008;Larsen et al, 2013;Lopes et al, 2015;Moraes et al, 2008;Roy et al, 2008;Santos et al, 2015), which means that there is still doubt about the role of the serratus anterior in these cases.…”

“…In contrast, 4 studies found no significant difference in muscle activation between patients and controls (Larsen et al, 2013;Moraes et al, 2008;Roy et al, 2008;Santos et al, 2015) (Table 6). et al, 2008 Elevation in the scapular plane 10 SIS (4 men, 6 women; mena age 28,6 y {20-38 y}) and 10 controls (4 men, 6 women; mean age 29 y {21-36 y}) Asymptomatic side comparison Asymptomatic side=symptomatic side Roy et al, 2008 90° abduction in frontal and scapular plane 33 SIS (11 men, 22 women; men age 47,9 y {26-59 y}) and 20 controls (7 men, 13 women; mean age 47,9 y {27-60 y}) SIS=controls Santos et al, 2007 Elevation in the scapular plane 8…”

“…Regarding muscle latency, the results showed in 5 studies that there is abnormal muscle latency (Helgadottir et al, 2011;Padke and Ludewig, 2013;). In contrast, 4 studies showed equal muscle latency between controls and patients (Larsen et al, 2013;Moraes et al, 2008;Roy et al, 2008;Santos et al, 2007). Roy et al, 2008 90 abduction in frontal and scapular plane 33 SIS (11 men, 22 women; men age 47,9 y (26-59 y)) and 20 controls (7 men, 13 women; mean age 47,9 y {27-60 y}) SIS=controls Table 4.…”
