“…Furthermore, there is another issue in MMT for the trunk muscles that is often a source of confusion for clinicians. MMT commonly employs two tests, namely the curl-up (CU) test and the double-leg-lowering (DLL) test to assess the trunk flexors 15,16) . These tests are considered suitable for distinguishing and assessing the muscle strength of the upper rectus abdominal (URA) and lower rectus abdominal (LRA) muscles, respectively 16,23) .…”

“…KIMCOM or BIODEX etc.). Manual muscle testing (MMT) is a method that is widely used in both the fi eld and clinical settings because it does not need any special equipment and is relatively simple to perform [15][16][17] . However, the issue of gender in MMT for trunk muscles remains unresolved 12,[17][18][19][20][21][22] .…”

Gender Differences in the Curl-up and the Double-leg-lower Tests

Abstract.[Purpose] The aim of this study was to quantitatively investigate gender differences in trunk muscle strength and activity and to verify the two proposed fi eld tests for screening the muscle strength of trunk flexors by use of surface EMG (sEMG). [Subjects and Methods] Fifty-four healthy young volunteers participated in this study and RA strength was evaluated using the curl-up (CU) and doubleleg-lower (DLL) tests. All muscle activity that occurred in the upper and lower RA sites during the two tests was recorded using sEMG. The sEMG data were then normalized using the maximum voluntary contraction. To investigate the validity of the two tests, the ratio of muscle activity between the upper and lower RA sites was calculated.[Results] The reliability of the CU and the DLL tests were estimated using the intraclass correlation coefficient and the values ranged from 0.84-0.96 and 0.93-0.98, respectively. Muscle activity was signifi cantly higher in females than in males in all tests except one of the DLL tests. The activity ratio with respect to each muscle grade was constant between the CU and the DLL tests. [Conclusion] Our results indicate that trunk muscle activity is affected by gender, and the tests should be selected according to purpose.

“…They were amplified, band-pass filtered (10-500 Hz), digitized and stored using a data acquisition system (Myosystem 1200; Noraxon, USA) at a sample frequency of 1000 Hz. The integrated EMG (IEMG) of the 5-s sample for each exercise were normalized to isometric maximal exertion tasks, by using a standard manual muscle test (%IEMG) 12) . Each isometric maximal exertion task was held for 5 s. To investigate the recruitment changes in each position, the %IEMG in positions B and F were normalized to the %IEMG in position D.…”

An Electromyographic Analysis of Trunk and Hip Extensor Muscles during Bridging Exercises -Effect of Voluntary Control of the Pelvic Tilt

et al. 2011

Abstract.[Purpose] A bridging exercise is most commonly used for people with weakness of the back and hip extensor muscles. However, little is known about the effect of voluntary control of the pelvic tilt on electromyographic (EMG) activities of the trunk and hip extensor muscles during bridging exercises. [Subjects] Sixteen healthy male volunteers participated in this study.[Methods] Bipolar electrodes were attached to the lumbar extensor muscle (L3), gluteus maximus, and medial hamstring. Subjects performed 3 bridging exercises with: discretionary control of the pelvis (position D), backward tilt of the pelvis (position B), and forward tilt of the pelvis (position F). While the subjects performed each bridging exercise, EMG signals were measured.[Results] The gluteus maximus showed significantly higher muscle activity in position B than in the other positions. We observed significantly increased activity of the lumbar extensor muscle (L3) in position F compared to the other positions.[Conclusion] The findings of this study should be considered when prescribing variations of the bridging exercise, as part of a lumbopelvic rehabilitation program.

“…The grounded electrode was placed over the iliac crest and EMG signals, which were continuously recorded during slumped sitting and co-contraction of the trunk muscles during sitting, were amplified, band-pass filtered (10-500 Hz), digitized, and stored by a data acquisition system (Noraxon Myosystem 1200, USA) at a sample frequency of 1000 Hz and a gain factor of 1000. The average muscle activity values over a 5-s sample period for each sitting posture were normalized to MVCs, which were obtained in isometric maximal exertion tasks using a standard manual muscle test described by Hislop et al [20] (%MVC). Each MVC was held for 5 s and the average EMG activity obtained for each muscle was used to determine the MVC.…”

Background and purpose: Slumped sitting is known to increase disc pressure and aggravate chronic low back pain. In addition, it has been recognized that co-contraction of the deep spine-stabilizing muscles enhances lumbar segmental stability and the sacro-iliac joint. The purpose of this study was to compare the electromyographic (EMG) activity of the trunk muscles and the muscle thickness of the transverse abdominis (TrA) during slumped sitting with the same parameters during co-contraction and investigate how co-contraction influences spinal curvature.Subjects and methods: Nine healthy male volunteers participated in the study. EMG signals were recorded during both sitting postures. In order to measure the muscle thickness of the TrA, ultrasound images were captured. While the subjects performed both sitting postures, spinal curvature was measured using a hand-held device.Results: Significantly more activity of the trunk muscles, with the exception of the rectus abdominis muscle, and significantly greater muscle thickness of the TrA were observed during co-contraction of the trunk muscles than during slumped sitting.Co-contraction also resulted in significantly increased lumbar lordosis and a greater sacral angle when compared to slumped sitting.Conclusion: In this study, it was demonstrated that the instructions given to the subjects on co-contraction of the trunk muscles during sitting increased muscle activity with the exception of the rectus abdominis muscle, muscle thickness of the TrA, and lumbar lordosis.
