Lumbopelvic stabilization exercise has become the most popular treatment method in lumbar rehabilitation since its effectiveness was shown in some aspects of pain and disability. The abdominal drawing-in maneuver (ADIM) has been extensively implemented to promote lumbopelvic stability. However, performing ADIM correctly is difficult even for healthy subjects, and it is time consuming to train people in ADIM. Thus, the purpose of this study was to compare abdominal muscle [rectus abdominalis (RA), external oblique (EO), and transverse abdominis/internal oblique (TrA/IO)] activity during lumbopelvic stabilization exercises (ADIM only, ADIM with a ball, maximum exhalation only, and maximum exhalation with a ball) performed in a supine position with feet against a wall. Fifteen healthy subjects were recruited for this study. Surface electromyography was used to measure abdominal muscle activity during lumbopelvic stabilization exercises. A one-way repeated-measures analysis of variance was used to determine the statistical significance of RA, EO, and TrA/IO muscle activity during four lumbopelvic stabilization exercises. Both-side TrA/IO muscle activity was significantly greater with maximum exhalation with a ball than with ADIM only or ADIM with a ball (p<.008). The results of this study suggest that maximum exhalation with a ball can be used as an effective lumbopelvic stabilization exercise to increase TrA/IO muscle activity in healthy subjects.

김태호,재우민,황병화 KEMA학회 2019 근골격계과학기술학회 Vol.3 No.1

Background Low back pain caused lumbopelvic instability and the passive and active stabilizing system and neural control subsystem control lumbopelvic stability. Purpose The aim of this study was to identify three-dimensional motions of pelvic and trunk during one leg standing applying the pelvic compression belt. Study design One group pre- and post-test design. Methods Twenty three healthy participants volunteered for this study. For the pre-test, their pelvic and trunk motions were measured during one leg standing in stance of the dominant side using equipment without application of pelvic compression belt. The participants wore pelvic compression belt for 20 minutes on a daily basis for a week in standing position to get used to application of pelvic compression belt. After one week training, the participants were measured during one leg standing in stance of the dominant side using equipment with application of pelvic compression belt for the post-test. The three-dimensional motion analysis system was used to measure the motion of anterior-posterior tilt, medial-lateral tilt, and rotation of the pelvis, as well as anterior-posterior flexion, lateral flexion, and rotation of the trunk during one leg standing. Results The motion of anterior-posterior tilt, medial-lateral tilt, and rotation of the pelvis were significantly decreased in the post-test than pre-test during one leg standing (p<0.05). Also the motion of anterior-posterior flexion, lateral flexion, and rotation of the trunk were significantly decreased in the post-test than pre-test during one leg standing (p<0.05). Effect sizes for pelvic anterior-posterior tilt, anterior-posterior flexion, lateral flexion, and rotation of the trunk were medium between pre-test and post-test during one leg standing (d=055–0.75). Conclusions This study found the motions of the pelvis and trunk were decreased by the passive support of the pelvic compression belt during one leg standing. This finding suggests that the pelvic compression belt will help to improve the stability of lumbopelvis in back pain patients with lumbopelvic instability.

김선엽,Kim, Suhn-Yeop 대한정형도수물리치료학회 1998 대한정형도수물리치료학회지 Vol.4 No.1

Activity of the trunk muscles is essential for maintaining stability of the lumbar spine because of the unstable structure of that portion of the spine. The central nervous system deals with stabilization of the spine by contraction of the abdominal and multifidus muscles in anticipations of reactive forces produced by limb movement. Recent evidence indicates that the lumbar multifidus muscle and transversus abdominis muscle may be involved in controlling spinal stability. Stabilization training in neutral spine is an integrated approach of education in proper posture and body mechanics along with exercise to improve strength, flexibility, muscular and cardiovascular endurance, and coordination of movement.

The purpose of this study was to determine the effects of lumbopelvic stabilization exercise on chronic low back pain, lumbosacral region angle, dynamic balance, trunk extensor endurance and pain index in middle aged women with chronic low back pain. Twelve middle aged women with chronic low back pain(Duration≥3month, visual analogue scale; VAS≥4, oswestry disability index; ODI≥7) were randomly divided into lumbopelvic stabilization exercise group(LSG, n=6) and control group(CON, n=6). Lumbopelvic stabilization exercise was performed for 60 min(warm up 10 min, exercise 40 min, cool down 10 min), three times a week for 8 weeks, with abdominal bracing. Lumbosacral region angle(lumbar lordotic angle; LLA, lumbosacral angle; LSA, sacrohorizontal angle; SHA), dynamic balance, trunk extensor endurance and pain index(VAS, ODI) were measured before and after 8-week exercise each groups. In results, lumbar lordotic angle(p=000) and lumbosacral angel(p=.041) showed significant interaction with groups and times in the LSG after exercise. Dynamic balance of Forward(p=.011, Backward(p=.008), Left(p=.001), Right(p=.OOQ), Left-Forward(p=.000), Right-Forward(p=.035), Left-Backward(p=.004) and Right-Backward(p=.000) showed significant interaction with groups and times in the LSG after exercise. Trunk extensor endurance showed significant interaction with groups and times in the LSG after exercise(p=.011). VAS showed significant interaction with groups and times in the LSG after exercise (p=.000). ODI showed significant interaction with groups and times in the LSG after exercise(p=.004). These results confirms that lumbopelvic stabilization exercise improve lumbosacral region angle and increased both dynamic balance and trunk extensor endurance, and decreased low back pain.

Purpose: Dysmenorrhea can be caused by misalignment of the pelvis. Since pilates stabilization exercise is a methods that affects pelvic alignment by inducing contraction of abdominal muscles, the purpose of this study is to determine whether dysmenorrhea is reduced when pilates stabilization exercise is applied. Methods: 47 dysmenorrhea patients were randomly divided into interventional(n=23) and control(n=24) groups. The intervention group performed Pilates stabilization exercise three times a week for 12 weeks, and the control group did not perform any intervention. Abdominal muscle thickness, lumbar pelvic alignment, and dysmenorrhea were measured before intervention, 6 weeks, and 12 weeks after intervention to determine the mean change over time and the effect of group and factor interactions(repeated measured ANOVA and contrast test for each period). Results: In the intervention group, the thickness of the transverse abdominis, internal oblique, and external oblique muscles were increased significantly by group and period (p <.05). The pelvic torsion, lordosis and dysmenorrhea were also significantly decreased by group and period. But the control group did not change significantly in any of the variables. Conclusion: Applying pilates stabilization exercise to women with dysmenorrhea may be an effective intervention that contributes to relieving dysmenorrhea by correcting the stability and alignment of the lumbar pelvis.

Effect of Shoulder Abduction Angles on EMG Activity of the Abdominal Muscles during Single Leg Holding on the Foam Roller

( Sung Joon Yun ),( Jun Hee Kim ) 대한물리치료학회 2020 대한물리치료학회지 Vol.32 No.4

Purpose: This study examined the electromyography (EMG) activity of the abdominal muscles and the ratio of the oblique abdominal muscle activity to the rectus abdominis muscle during a single-leg holding position with isometric shoulder abduction (SLHISA) in the supine position on a foam roller. Methods: Nineteen healthy males were recruited to the study. Each subject was asked to lay on a round foam roller and perform single-leg (nondominant) holding with contralateral shoulder abduction to one of three angles (45°, 90°, or 135°) in random order. The surface EMG signals of the bilateral rectus abdominis (RA), external oblique abdominis (EO), and combined internal oblique abdominis (IO) and transverse abdominis (TrA) muscle were collected during the tasks. The EO/RA and (IO & TrA)/RA ratios were determined using surface EMG. One way repeated measure ANOVA with three SLHISAs was used to assess the significant abdominal muscle EMG activity and the ratio of the oblique abdominal muscles activity to the RA muscle. The statistical significance level was p<0.05. Results: The results were as follows. The SLHISA 135° showed significantly higher EMG activity of both RAs, left EO, and right IO & TrA muscles (p<0.05). The right EO and left IO and TrA muscles/RA were significantly different among the SLHISA angles. The SLHISA 45° showed a significantly greater ratio of right EO/RA and left IO & TrA/RA (p<0.05). Conclusion: SLHISA on a foam roller is useful for lumbopelvic stabilization exercise by increasing the activity and recruiting a specific pattern of the oblique abdominal muscle.

Effects of the Abdominal Hollowing and Abdominal Bracing Maneuvers on the Pelvic Rotation Angle during Leg Movement

이원휘 KEMA학회 2020 근골격계과학기술학회 Vol.4 No.2

Background: Abdominal hollowing (AH) and abdominal bracing (AB) are well-known stabilization maneuvers used in rehabilitation and training programs. However, few studies have examined how these two techniques affected the lumbopelvic stability during leg movements. Purpose: This study aims to compare pelvic rotation angles during leg movements with AH or AB maneuver. Study design: Comparative, repeated-measures design Methods: This study included 20 male healthy participants. After attaching motion sensor, we asked the participants to perform the two leg movements, straight leg raise (SLR), and bent knee fallout, in three conditions, including abdominal resting (AR), AH, and AB maneuvers, and collected and compared the pelvic rotation angles during each condition. Results: The difference between the three conditions for pelvic rotation angles of both leg movements was significant (p<0.05). When performing SLR or bent knee fallout with AB maneuver, the pelvic rotation angle decreased more significantly than that in performing movements with AR or AH maneuver (p<0.05). When performing SLR or bent knee fallout with AH maneuver, the pelvic rotation angle decreased more significantly than that in performing movements with AR maneuver (p<0.05). Conclusions: This study indicated that the AB maneuver is more effective in SLR, and bent knee fallout with lumbopelvic stabilization exercise than the AH maneuver.

허리골반 안정화 운동이 다리정렬과 균형에 미치는 영향

김기송 호서대학교 기초과학연구소 2016 기초과학연구 논문집 Vol.24 No.1

Swiss ball exercise influences on leg length discrepancy, hamstring flexibility discrepancy, and balance ability in subjects with malalignment syndrome. Twenty subjects with malalignment syndrome participated in a exercise program using a Swiss ball which consisted of three sets of ten repetitions per set. All subjects’ leg length discrepancy, hamstring flexibility discrepancy, and balance ability were measured twice: pre, and post intervention. Functional leg length was measured with a tape measure to determine leg length discrepancy. Hamstring flexibility discrepancy was determined by measuring active knee extension range with a goniometer. Balance ability was measured by single leg stance time on a balance board. Leg length discrepancy and hamstring flexibility discrepancy were decreased post—intervention, balance ability on both legs increased post—intervention. These findings suggest that lumbopelvic stabilization exercise using a Swiss ball decreases leg length discrepancy and hamstring flexibility discrepancy while increasing balance ability in subjects with malalignment syndrome, indicating that these exercises improve lower extremity alignment and may prevent future problems such as lower back pain.

Background: Cervical dysfunction is a common pathomechanical marker in individuals with forward head posture (FHP). To overcome the limitations of the isometric chin-tuck (ICT) exercise, dynamic neuromuscular stabilization (DNS), which emphasizes an entire spinal chain exercise, has recently shown promising clinical results. Objects: Purpose of this study was to compare the immediate effects between ICT and DNS techniques. Methods: 43 young subjects (mean age, 24.0±5.0 years) were recruited. Group of subjects with FHP were measured under baseline, ICT, and DNS conditions. Outcome measures included sitting height, longus colli (LC) and sternocleidomastoid (SCM) muscle thickness and LC/SCM thickness ratio. One-way repeated measures ANOVA was used to compare the continuous dependent variables among FHP, ICT, and DNS conditions at p<.016. Results: Both ICT and DNS exercise conditions yielded significantly increased LC muscle thickness, LC/SCM thickness ratio and sitting height than did FHP condition (p<.0001, respectively). Sitting height was significantly greater in DNS exercise than in the ICT exercise (p<.0001). Conclusion: The present results demonstrated that sitting height was greater in the DNS exercise than in the ICT exercise, as well as both corrective postural training exercises were effective on LC/SCM muscle balance ratio when compared with the baseline FHP condition. Therefore, it is considered that DNS exercise can be the recommended exercise for people with FHP.
