“…1,2 Based on this concept, we operationally defined static core stability as the active core stabilization achieved by selective activation of the transverse abdominis (TrA) and internal oblique (IO) muscles with a minimal contraction of the other superficial abdominal muscles during the abdominal drawing-in maneuver (ADIM) in the prone position. 3 However, core instability recently has been identified as a pathomarker for low back pain (LBP). 4,5 In fact, Luoto et al 6 examined static unipedal postural stability in chronic LBP and found increased postural sway as evidenced by greater velocity of center-of-pressure (COP) sway than in normal controls.…”

Context:The exact neuromechanical nature and relative contribution of the abdominal drawing-in maneuver (ADIM) to postural instability warrants further investigation in uninjured and injured populations.Objective: To determine the effects of the ADIM on static core and unipedal postural stability in nonathletes with core instability.Design: Controlled laboratory study. Setting: University research laboratory. Patients or Other Participants: A total of 19 nonathletes (4 women: age ¼ 22.3 6 1.3 years, height ¼ 164.0 6 1.7 cm, mass ¼ 56.0 6 4.6 kg; 15 men: age ¼ 24.6 6 2.8 years, height ¼ 172.6 6 4.7 cm, mass ¼ 66.8 6 7.6 kg) with core instability.Intervention(s): Participants received ADIM training with visual feedback 20 minutes each day for 7 days each week over a 2-week period.Main Outcome Measures(s): Core instability was determined using a prone formal test and measured by a pressure biofeedback unit. Unipedal postural stability was determined by measuring the center-of-pressure sway and associated changes in the abdominal muscle-thickness ratios. Electromyographic activity was measured concurrently in the external oblique, erector spinae, gluteus medius, vastus medialis oblique, tibialis anterior, and medial gastrocnemius muscles.Results: All participants initially were unable to complete the formal test. However, after the 2-week ADIM training period, all participants were able to reduce the pressure biofeedback unit by a range of 4 to 10 mm Hg from an initial 70 mm Hg and maintain it at 60 to 66 mm Hg with minimal activation of the external oblique (t 18 ¼ 3.691, P ¼ .002) and erector spinae (t 18 ¼ 2.823, P ¼ .01) muscles. Monitoring of the pressure biofeedback unit and other muscle activations confirmed that the correct muscle contraction defining the ADIM was accomplished. This core stabilization was well maintained in the unipedal-stance position, as evidenced by a decrease in the center-of-pressure sway measures (t 18 range, 3.953-5.775, P , .001), an increased muscle-thickness ratio for the transverse abdominis (t 18 ¼ À2.327, P ¼ .03), and a reduction in external oblique muscle activity (t 18 ¼ 3.172, P ¼ .005).Conclusions: We provide the first evidence to highlight the positive effects of ADIM training on core and postural stability in nonathletes with core instability.Key Words: center of pressure, core stabilization, formal test Key PointsStatic core stability and unipedal postural stability were enhanced in nonathletes with core instability after abdominal drawing-in maneuver training augmented with rehabilitation ultrasound imaging and electromyographic feedback. Abdominal drawing-in maneuver training using rehabilitation ultrasound imaging and electromyography effectively improved morphologic changes in transverse abdominis muscle thickness and the neuromuscular pattern of an overactive superficial external oblique muscle, contributing to static core stability and unipedal postural stability. Researchers should further investigate the relationship between dynamic core and unipedal postural sta...

“…18 On the contrary, bilateral lower extremity raising in a supine position results in leg weight as external resistance, strengthening trunk muscles as an effective exercise for stabilization. 19 As examined through previous studies, the abdominal muscles play a very important role in physical stability.…”

Purpose: This study was to investigate the differences abdominal muscles activities of according to hip adductor contraction levels 20% (mild), 50% (moderate), and 70% (strong) of MVIC on during bilateral lower extremity raising exercise on supine. Methods: The subjects of the study were a total of 39 persons including 23 healthy males and 16 females, who performed bilateral lower extremity raising exercise in 20%, 50%, 70% MVIC hip contraction. Muscle activities were measured by using S-EMG in RA (rectus abdominis), IO (internal oblique), and EO (external oblique). Results: Muscle activity of the internal oblique abdominal muscle and external oblique abdominal muscle, their activities were also greatest with the adductor contraction size at 70% and there was statistically significant difference when compared with the adductor contraction size at 20% and 50% (p< 0.05). As for the rectus abdominis muscle according to the size of contraction of the adductor was greatest at 70%, without statistically significant difference (p> 0.05). Conclusion: bilateral lower extremity raising with strong hip joint adductor contraction was effective exercise to strengthen abdominal muscles. If subjects could not perform strong hip adductor contraction, moderate contraction is effective abdominal muscle contraction exercise. The contraction size of the adductor is small, weak contraction may trigger middle level contraction and therefore appropriate application of the exercise program of bilateral leg raising may result in great effect as a lumbar stabilization exercise.

“…Core training or lumbar stabilization which is aimed at the muscles of the trunk, abdomen and pelvis [4]. The goals of spinal stabilization are to (a) increases the capacity of the muscular stabilization system to maintain the neutral zone of the spine within its physiological limits, (b) increases the low back tolerance to insult through the conditioning of key musculature, (c) restore muscle size, strength, and endurance, d) re-establish coordinated muscle activity as required for prevention of recurrence and restoration of function and, (e) reduce pain associated with spinal instability [5][6][7][8][9]. Evidence suggests that McKenzie extension exercises on low back pain patients when administered there was greater decrease in pain and disability [10][11][12].…”

Aim: The purpose of the study is to find out the effectiveness of lumbar stabilization exercises and extension exercises in patients with sub acute non-specific low back pain. Materials and Methods: 30 patients with non specific sub acute low back pain and no clinical signs suggesting spinal instability were recruited (Stabilization training: n=15; Mc Kenzies back extension: n=15). Both groups received 6 weeks of exercises intervention. Outcome measure were pain (Visual analog scale), range of motion (inch tape), disability (Modified Oswestry disability questionnaire) which were measured before and after intervention.Results: Both groups showed improvement post intervention. Statistically significant difference was observed between the 2 groups for relief of pain (mean difference=0.64, p=0.003), increase in range of motion (mean difference= 0.32,p=0.005) and reduction in disability scores (mean difference=3.40, p=0.003) favoring the trunk stabilization exercises. Conclusion:The lumbar stabilization exercises programme has shown a significant improvement in outcome measures and reduced the disability to a greater extent with that of back extension exercise approach among subjects with sub acute non specific low back pain.
