“…Multiple papers report the lateral symmetry of abdominals (both rectus and oblique) [41,42]. However our analyses revealed that the relationship of male gender with thickness in the right oblique area was found to be significant.…”

Abstract:The ability to assess geometric asymmetry in the torsos of individuals is important for detecting Adolescent Idiopathic Scoliosis (AIS). A markerless technique using Surface Topography (ST) has been introduced as a non-invasive alternative to standard diagnostic radiographs. The technique has been used to identify asymmetry patterns associated with AIS. However, the presence and nature of asymmetries in the healthy population has not been properly studied. The purpose of this study is therefore to identify asymmetries and potential relationships to development factors such as age, gender, hand dominance and unilateral physical activity in healthy adolescents. Full torso scans of 83 participants were analyzed. Using Geomagic, deviation contour maps (DCMs) were created by reflecting the torso along the best plane of sagittal symmetry with each spectrum normalized. Two classes of asymmetry were observed: twist and thickness each with subgroupings. Averaged OPEN ACCESSSymmetry 2015, 7 1437 interobserver and intraobserver Kappas for twist subgroupings were 0.84 and 0.84, respectively, and for thickness subgroupings were 0.53 and 0.63 respectively. Further significant relationships were observed between specific types of asymmetry and gender such as females displaying predominately twist asymmetry, and males with thickness asymmetry. However, no relationships were found between type of asymmetry and age, hand dominance or unilateral physical activity. Understanding asymmetries in healthy subjects will continue to enhance assessment ability of the markerless ST technique.

“…[10][11][12] The ASLR has established reliability and validity data in women with posterior pelvic pain associated with pregnancy, 10 and has also been reported as a useful test for unilateral lumbopelvic pain. 24 Mens and colleagues 10 found the ASLR to have higher intrarater reliability than the AHAbd test, with an ICC 1,1 of 0.83. For the BKFO test, the patient is positioned in supine, with 1 lower extremity flexed with the foot on the table, and is asked to externally rotate and abduct the flexed limb as far as possible without rotating the pelvis.…”

“…1,37,69,70,72 For example, Teyhen et al 70 monitored the thickness of the IO and TrA muscles in 15 participants with unilateral lumbopelvic pain and 15 agematched and gender-matched controls, during the performance of an active straight leg raise test. They reported a 24% and 11% increase in TrA and IO thickness, respectively, in the control group, and significantly smaller (6% and 6%, respectively) increases in thickness in the lumbopelvic pain group.…”

“…Although, for reasons explained above, it would be inappropriate to assume that the smaller change in thickness in the lumbopelvic pain cohort was due solely to a decreased amount of muscle activity, knowing that a 24% and an 11% change in thickness of the TrA and IO, respectively, is expected during an active straight leg raise test is potentially useful. In addition to this example and in keeping with the abdominal wall muscles as an example, investigators have measured thickness, length, and/or CSA in both resting 7,12,54,59,63 and dynamic conditions (eg, abdominal drawing-in maneuver, 11,69 respiration, 1,72 balance, upper limb tasks, 51 and walking tasks) within various (low back, lumbopelvic, and pelvic girdle pain, 67 amputees, 62 postpartum, 8 and healthy) cohorts. These studies provide normal resting values and/or describe patterns of architectural change.…”
