“…In addition to these factors, psychosocial aspects may also be associated [35,36], including social relationships, self-esteem, mood, social roles, satisfaction with life and independence. Moreover, activation of abdominal bracing may limit movements and increase mechanical stress, providing greater energy expenditure [13,37]. In patients with chronic low back pain, the transverse abdominal muscle seems not to exhibit delayed activation [12], and multifidus activity may be changed, independent of abdominal bracing activation [13].…”

“…However, although a number of earlier studies proved that this factor may be one of the causes of low back pain [44,45], there was no association between pain and trunk muscle weakness (p < 0.05). In addition to the fact that abdominal bracing activation increases thoracic flexion [13], and given that changes in pelvic alignment may potentially alter trunk alignment [46][47][48], this association can be justified by the near-direct anatomical, kinetic and functional association between the segments involved in trunk extension movement and pelvic control.…”

“…Their stability provides dynamic and efficient postural control, creating balance around the hip complex [10] and promoting a stable base for the limb muscles [11]. However, several authors have discussed the real influence of transverse abdominal and multifidus muscle activation in situations of chronic pain [12,13].…”

Introduction: The protective role of muscles in the passive structures of the spine means that their stability and consequent maintenance are associated with pain, especially in the region of the lumbo-pelvic-hip complex. Objective: To determine the prevalence of pain and its association with muscle deficits in higher education students. Method: Descriptive, observational, cross-sectional study that evaluated 120 university students through questionnaires (sample characterization, Nordic musculoskeletal symptoms, pain visual analogue scale and international physical activity). Trunk muscle strength and bridge tests with unilateral knee extension (pelvic alignment) were performed. Results: A high prevalence of pain was found in the lower back (58.41%). There was no association between the presence of pain, muscle strength and pelvic alignment (p> 0.05). There was an association between the trunk extension and pelvic tilt tests (p = 0.009). Conclusion: A high prevalence of low back pain, poor performance in the trunk muscle endurance tests and mild and moderate pelvic misalignment were identified. There was no association between pain, trunk muscle weakness and pelvic misalignment. There was an association between pelvic misalignment and trunk extensor muscle weakness.

“…Studies on abdominal bracing and abdominal hollowing techniques have been conducted on subjects in standing to supine position [13], supine position, quadruped posture [14], side-lying position [15], and standing in place [16]. Comparative studies on abdominal hollowing techniques are frequently conducted with subjects in place, however, studies conducted on subjects with abdominal bracing while out of place, such as gait, are lacking.…”

Objective: This study aimed to investigate the effect of the application of abdominal brace techniques on muscle activity of the trunk and lower extremities when walking. Design: Cross-sectional study Methods: This study was conducted on 26 healthy adults in their 20s, and the subjects performed two conditions in random order: walking with the abdominal bracing technique and walking in an abdominal relaxation state (normal gait). Muscle activity was measured on the dominant side of all subjects using surface electromyography, and the attachment sites were the erector spinae, external oblique, internal oblique, vastus lateralis, and vastus medialis oblique muscles. Each condition was measured three times to calculate and analyze the average value. Results: When walking using the abdominal brace technique, the muscle activity of the erector spinae, external oblique, internal oblique, and vastus lateralis increased significantly (p＜0.05), and the muscle activity of the vastus medialis increased as well but was not significant. Conclusions:The results of this study indicate that it is possible to be used as an effective guide to increasing the muscle activity and stability of the trunk and lower extremities through the application of the abdominal bracing technique during walking.

BackgroundTrunk co‐contraction during lifting may reflect a guarded motor response to a threatening task. This work estimated the impact of pain catastrophizing on trunk co‐contraction during lifting, in people with and without low back pain.MethodsAdults with high pain catastrophizing (back pain: n = 29, healthy: n = 7) and low pain catastrophizing (back pain: n = 20, healthy: n = 11), performed 10 repetitions of a lifting task. Electromyography data of rectus abdominis, erector spinae and external oblique muscles were collected, bilaterally. Co‐contraction indices were determined for rectus abdominis/erector spinae and external oblique/erector spinae pairings, bilaterally. Pain catastrophizing was measured using the pain catastrophizing scale and task‐specific fear using the Photograph series of daily activities scale. Three‐way mixed ANOVAs tested the effects of group (back pain vs. healthy), pain catastrophizing (high vs. low), lifting phase (lifting vs. replacing) and their interactions.ResultsThere were no main effects of pain catastrophizing, lifting phase, nor any interactions (p > 0.05). Group effects revealed greater co‐contraction for bilateral erector spinae/rectus abdominis pairings (but not erector spinae‐external oblique pairings) in people with back pain, compared to healthy participants, independent of pain catastrophizing and lifting phase (p < 0.05). Spearman correlations associated greater task‐specific fear and greater erector spinae‐left external oblique co‐contraction, only in people with back pain (p < 0.05).ConclusionsGreater co‐contraction in the back pain group occurred independent of pain catastrophizing, as measured with a general questionnaire. A task‐specific measure of threat may be more sensitive to detecting relationships between threat and co‐contraction.Significance StatementThis work contributes evidence that people with back pain commonly exhibit trunk co‐contraction when lifting. The lack of a relationship between pain catastrophizing and trunk co‐contraction, however, challenges evidence linking psychological factors and guarded motor behaviour in this group. Together, this suggests that other factors may be stronger determinants of co‐contraction in people with LBP or that a general construct like pain catastrophizing may not accurately represent this relationship.
