Effects Of Abdominal Drawing-in Maneuver Research Articles

Comparison of core stabilization techniques on ultrasound imaging of the diaphragm, and core muscle thickness and external abdominal oblique muscle electromyography activity.

To restore core stability, abdominal drawing-in maneuver (ADIM), abdominal bracing (AB), and dynamic neuromuscular stabilization (DNS) have been employed but outcome measures varied and one intervention was not superior over another. The purpose of this study was to compare the differential effects of ADIM, AB, and DNS on diaphragm movement, abdominal muscle thickness difference, and external abdominal oblique (EO) electromyography (EMG) amplitude. Forty-one participants with core instability participated in this study. The subjects performed ADIM, AB, and DNS in random order. A Simi Aktisys and Pressure Biofeedback Unit (PBU) were utilized to measure core stability, an ultrasound was utilized to measure diaphragm movement and measure abdominal muscles thickness and EMG was utilized to measure EO amplitude. Analysis of variance (ANOVA) was conducted at P< 0.05. Diaphragm descending movement and transverse abdominis (TrA) and internal abdominal oblique (IO) thickness differences were significantly increased in DNS compared to ADIM and AB (P< 0.05). EO amplitude was significantly increased in AB compared to ADIM, and DNS. DNS was the best technique to provide balanced co-activation of the diaphragm and TrA with relatively less contraction of EO and subsequently producing motor control for efficient core stabilization.

Effects of abdominal drawing-in maneuver with or without prior iliopsoas stretching on gluteus maximus activity during prone hip extension.

Prone hip extension (PHE) has been investigated to strengthen the hip joint and back extensor muscles. However, it has not been compared with various PHE exercises in individuals with iliopsoas shortness. This study compared pelvic compensation and hip and back extensor muscle activities in individuals with iliopsoas shortness during prone hip extension (PHE) using the abdominal drawing-in maneuver alone (PHEA) and after iliopsoas stretching (PHEAS). Twenty-five individuals with iliopsoas shortness were included in the study. Electromyography was used to investigate bilateral erector spinae (ES) and ipsilateral gluteus maximus (GM), biceps femoris (BF), and semitendinosus (ST) muscles during PHE, PHEA, and PHEAS. Pelvic anterior tilting and rotation angles were measured during each PHE exercise via electromagnetic motion tracking. A modified Thomas test was used to examine the hip extension angle before and after iliopsoas stretching. One-way repeated-measures analysis of variance was used to investigate differences in pelvic anterior tilting and rotation angle and in hip and back extensor muscle activities among PHE, PHEA, and PHEAS. The level of statistical significance was set at α= 0.01. GM muscle activity was significantly greater with PHEAS, compared to PHE and PHEA (p< 0.01). Bilateral ES and ipsilateral BF and ST muscle activities were significantly reduced with PHEAS, compared to PHE and PHEA (p< 0.01). Anterior pelvic tilting and rotation angles were significantly reduced with PHEAS, compared to PHE and PHEA (p< 0.01). PHEAS is recommended to selectively strengthen GM muscles with minimal BF and ST muscle activities and pelvic compensation in individuals with iliopsoas shortness. The abdominal drawing-in maneuver (ADIM) after iliopsoas stretching is more efficient than ADIM alone during PHE, especially in individuals with iliopsoas shortness.

Effect of abdominal drawing-in maneuver with prone hip extension on muscle activation of posterior oblique sling in normal adults.

[Purpose] There have been many studies on ipsilateral erector spinae in regard of prone hip extension (PHE). However, mediating methods have been focusing on the reinforcement of gluteus. Hereupon, this study is intended to identify how an increase of abdominal drawing-in maneuver influences on posterior oblique sling (POS) and suggest a mediating method to effectively reinforce them. [Participants and Methods] This study has been conducted on normal male (10) and female (10), and participants were asked to prove PHE exercise and abdominal drawing-in maneuver prone hip extension exercise (ADIM PHE). Surface electromyography (EMG) was recorded from the contralateral latissimus dorsi, ipsilateral erector spinae, ipsilateral gluteus maximus, and ipsilateral biceps femoris. A pared t-test was used to compare muscle activity POS. [Results] EMG activity of the contralateral latissimus dorsi, ipsilateral gluteus maximus was significantly greater performed ADIM PHE than PHE. As for ipsilateral erector spinae muscle, ipsilateral biceps femoris activation was lower in ADIM PHE than PHE. [Conclusion] According to the results of this study, abdominal drawing-in maneuver seems to be an important factor that influences on muscular activation of POS.

Effects of real-time ultrasound as biofeedback on transversus abdominis activation level in patients with chronic low back pain

Objective To investigate the effects of abdominal drawing-in maneuver with real-time ultrasound biofeedback on transversus abdominis activation level during functional tasks in different positions in patients of chronic low back pain with stabilization-deficit. Methods Nineteen patients of chronic low back pain with stabilization-deficit were randomly divided into verbal instruction group(n=9) and ultrasound biofeedback group(n=10), and received abdominal drawing-in maneuver with verbal instruction and ultrasound biofeedback respectively. Percentage changes of transversus abdominis thickness during supine and upright loaded tasks were compared before and after intervention. Results After intervention, percentage changes of transversus abdominis thickness increased significantly in verbal instruction group during supinehip external rotation, straight leg raising and upright loaded functional tasks (P 0.05). Conclusions Ultrasound image could effectively assess the thickness changes of transversus abdominis in patients with chronic low back pain during supine and upright loaded functional tasks. Ultrasound image could provide chronic low back pain patients with real-time and dynamic visual feedback. However, compared with verbal instruction, adding real-time ultrasound biofeedback to abdominal drawing-in maneuver does not further increase the transversus abdominis activation level. Key words: Ultrasonography; Transversus abdominis activation; Chronic low back pain

The effects of abdominal drawing-in maneuver during stair climbing on muscle activities of the trunk and legs.

The purpose of this study was to investigate effects of abdominal drawing-in maneuver (ADIM) on the muscular activity of the trunk and the lower limbs during stair ascent. The subjects were healthy 15 men and 8 women who were in their 20s. After maintaining ADIM by using a pressure biofeedback unit for 15 min, the subjects performed stair ascent and their muscular activity of the right trunk and the legs was measured to determine difference between when the subjects maintained ADIM and did not. The activities of the sternocleidomastoid, the splenius capitis, the rectus abdominis (ABD), the external abdominal oblique (EO), the transverse abdominis (TRA), the elector spinae (ES), the vastus medialis (VM), and the vastus lateralis (VL) were measured using surface electromyogram (TM DTS). The collected data were statistically processed by the SPSS ver. 18.0 and analyzed with a paired t-test. The muscular activities of the TRA, VM, and VL significantly increased (P<0.05), while the activity of the ES significantly decreased (P<0.05) during stair ascent when the ADIM was maintained than when it was not. In conclusion, the stair ascent with ADIM maintained activated the abdominal muscles to control trunk balance and perform lumbar stability, simultaneously reducing excessive lumbar lordosis or pelvic anterior tilt which will help to improve the function of the musculoskeletal system.

Effects of abdominal drawing-in maneuver with pressure biofeedback, foam-roller and quadruped on lumbopelvic stability and muscle activities in lumbar rotation syndrome.

The abdominal drawing-in maneuver (ADIM) exercise has been commonly applied to recover lumbopelvic stability and normal movement in the clinical field. Although many researchers investigated its effects using several methods, there is further need for comparing those methods. The purpose of this study was to assess the effects of ADIM with three different methods including a pressure biofeedback unit, a foam-roller, and the quadruped posture on lumbopelvic rotation and muscle activities. Twenty-five healthy participants (14 males, 11 females) who volunteered for this study were randomly divided into three intervention groups. We obtained pre- and postintervention data through application of a three-dimensional motion analysis system and a surface electromyography. Results showed that lumbopelvic rotation degree was significantly decreased in all groups (P<0.05). The muscle activities of external oblique, internal oblique of left side, and gluteus maximus were significantly increased (P<0.05). The muscle activities of erector spinae and biceps femoris were not significantly different (P>0.05). The muscle activity of internal oblique of the right side showed significant differences (P<0.05), between ADIM with pressure biofeedback group and ADIM with foam-roller group, and ADIM with foam-roller group and ADIM with quadruped group. Three kinds of ADIM were effective to recover lumbopelvic stability. This study suggests that the proper method of ADIM should be applied to a given patient considering abilities to maintain equilibrium and to control muscular strength.

To determine the effect of abdominal drawing-in maneuver (ADIM) on the activity of scapular stabilizer muscles during push-up plus exercise (PUP) in subjects with scapular winging (SW), by investigating the electromyography (EMG) amplitude of upper trapezius (UT), lower trapezius (LT), and serratus anterior (SA) activity, the UT/LT and UT/SA activity ratio, and the amount of SW.

Effect of Abdominal Drawing-In Maneuver with Unstable Surface on Lumbopelvic Stability in People with Lumbar Rotation

The abnormal movements often occur in lumbar region and they cause pains commonly. The number of painful people is increasing and researchers have studied to find the most proper physical therapy treatment. The purpose of the study was to analyze the effect of abdominal drawing-in maneuver exercise with unstable surface for the people with lumbar rotation. We hypothesized that people who exercise abdominal drawing-in maneuver with foam-roller would display decreased abnormal lumbopelvic rotation and achieve the better control ability after performing hip extension on a foam-roller. Kinematic data collected before and after intervention for hip extension on quadruped were analyzed. The subjects (N=9) displayed significantly decreased lumbopelvic rotation degree. This finding suggests that people with lumbar rotation can improve their ability to control lumbopelvic movement by exercising abdominal drawing-in maneuver with foam-roller.

Effect of abdominal drawing-in maneuver during hip extension on the muscle onset time of gluteus maximus, hamstring, and lumbar erector spinae in subjects with hyperlordotic lumbar angle.

BackgroundThe abdominal drawing-in maneuver (ADIM) is used to prevent abnormal movements of the lumbar spine and pelvis during therapeutic exercises. This study compared the effects of ADIM on the muscle onset time of the hamstring, gluteus maximus, and erector spinae muscles during prone hip extension exercise in subjects with or without hyperlordotic lumbar angle. Forty healthy adults (18 male, 22 female) were recruited for this study.MethodsThe lumbar lordotic angles and pelvic tilt angles of the subjects were measured using the Avaliação postural analysis software. The subjects were divided into two groups: the lumbar hyperlordotic angle (LHLA) and lumbar normal lordotic angle (LNLA) groups. The muscle contraction onset time of the hamstring, gluteus maximus, and erector spinae were assessed using surface electromyography.ResultsDuring ADIM application, the muscle contraction onset time of the gluteus maximus was significantly increased in the LHLA group compared with the LNLA group.ConclusionsADIM application during prone hip extension was more effective for gluteus maximus onset time in the LHLA group. Therefore, ADIM during prone hip extension may be useful for gluteus maximus training in individuals with lumbar hyperlordosis.

Comparisons of Trunk Muscle Activity During Arm Lift in Prone and Standing Positions With and Without Abdominal Drawing-in Maneuver

The aim of this study is to compare the effect of abdominal drawing-in maneuver (ADIM) on lower trapezius (LT), serratus anterior (SA), and erector spinae (ES) muscle activity during arm lifts in prone and standing positions. Twenty healthy subjects were recruited, and NoraxonTeleMyo 2400T was used to collect electromyographic signals from the LT, SA, and ES muscles. A two-way repeated analysis of variance (ANOVA) used a significance level of .05. If a significant interaction was found, pairwise comparisons were performed with a Bonferroni adjustment (.05/4=.013). The results of the study were as follows: 1) In LT, no significant ADIM by position interaction was found (=.356, p=.558). There was a significant main effect for ADIM. LT muscle activity with ADIM was significantly greater compared with muscle activity without ADIM (=82.863, p=116.401, p=8.687, p=.008). There were significant differences in all pairwise comparisons. The greatest SA muscle activity was observed in the standing position with ADIM. 3) In ES, significant ADIM by position interaction was found (=122.473, p
