“…The gluteus maximus activation was also delayed, suggesting an inability to compress and stabilize the sacroiliac joint and pelvis with associated lower extremity movement. Overall, these studies 28,29,32 illustrate alterations in muscle recruitment, suggesting that deficiencies in core stabilization and load transfer muscles may be related to lower extremity function and injury.…”

“…12,13,20,28,29,32 The transversus abdominus and multifidus—local stabilizer muscles—display changes in recruitment 12,13,20,28,29,32 and morphology 44 that limit their ability to effectively stabilize the spine and provide accurate proprioceptive information. Hodges et al examined core muscle recruitment patterns during upper 29 and lower 28 extremity movements in LBP patients compared with healthy controls.…”

“…Interestingly, the majority of studies report alterations in muscle recruitment (ie, timing, amplitude, and endurance), not decreased strength, indicating that core dysfunction may be more of a neuromuscular control problem than a strength problem. 28,29,32 …”

Context:Enhancing core stability through exercise is common to musculoskeletal injury prevention programs. Definitive evidence demonstrating an association between core instability and injury is lacking; however, multifaceted prevention programs including core stabilization exercises appear to be effective at reducing lower extremity injury rates.Evidence Acquisition:PubMed was searched for epidemiologic, biomechanic, and clinical studies of core stability for injury prevention (keywords: “core OR trunk” AND “training OR prevention OR exercise OR rehabilitation” AND “risk OR prevalence”) published between January 1980 and October 2012. Articles with relevance to core stability risk factors, assessment, and training were reviewed. Relevant sources from articles were also retrieved and reviewed.Results:Stabilizer, mobilizer, and load transfer core muscles assist in understanding injury risk, assessing core muscle function, and developing injury prevention programs. Moderate evidence of alterations in core muscle recruitment and injury risk exists. Assessment tools to identify deficits in volitional muscle contraction, isometric muscle endurance, stabilization, and movement patterns are available. Exercise programs to improve core stability should focus on muscle activation, neuromuscular control, static stabilization, and dynamic stability.Conclusion:Core stabilization relies on instantaneous integration among passive, active, and neural control subsystems. Core muscles are often categorized functionally on the basis of stabilizing or mobilizing roles. Neuromuscular control is critical in coordinating this complex system for dynamic stabilization. Comprehensive assessment and training require a multifaceted approach to address core muscle strength, endurance, and recruitment requirements for functional demands associated with daily activities, exercise, and sport.

“…If the GM works inappropriately during gait, it can cause back pain, resulting from a lack of shock-absorption at the sacroiliac joint2 ) , and Hungerford et al3 ) suggested that the activity of GM in the legs of patients with sacroiliac joint pain is delayed, and that the biceps femoris shows early activation to compensate for this delay. Moreover, individuals with limited movement of GM show fast movement of the hamstring muscles (HAM) and erector spinae muscles for better stability of their back4, 5 ) .…”

[Purpose] The present study examined the effects of knee flexion angle on hip extensor muscle activity. [Subjects and Methods] Twenty healthy subjects maintained knee flexion angles of 0°, 30°, 60°, 90° and 110° in the prone position and performed maximal voluntary contraction in hip extension. Maximum torque in hip extension at the different angles was measured, and surface electromyogram activities of the gluteus maximus (GM), biceps femoris (BF) and semitendinosus (ST) were recorded and normalized by the maximum voluntary isometric contraction (MVIC). [Results] The maximum torque of the hip extensor showed significant decreases between 0°and 60°, 90° and 110° of knee flexion. The muscle activity of BF was significantly high at 0°, and GM showed a significantly higher activity than both BF and ST at 60°, 90°and 110° of knee flexion. [Conclusion] The maximum torque in hip extension and muscle activities of BF and ST were significantly high at 0° but they decreased at knee flexion angles of more than 60°. Therefore, we consider that more than 60° of knee joint flexion is required to increase GM activity, and to reduce the muscle activities of BF and ST.

“…However, because the structure of the spine is more unstable than those of other bones, the roles of the deep muscles are particularly important for spinal stabilization1 ) . Representative deep muscles of lumbar stabilization include the transversus abdominis muscle (Tra) and the multifidus muscle2 ) . The fact that Tra greatly contributes to lumbar stabilization has been proven by many studies, and the importance of this muscle has been established3 ) .…”

[Purpose] The purpose of the present study was to analyze the correlations of the thicknesses of the transversus abdominis muscle (Tra) and the internal obliquus abdominis muscle (Io) with static lumbar stability (SLS), dynamic lumbar stability (DLS), and balance. [Subjects] The subjects of the present study were 40 female university students who had no physical defects or pain. [Methods] The thicknesses of Tra and Io muscles were measured using an ultrasonic imaging diagnostic unit. SLS and DLS were measured using a Pressure Biofeedback Unit (PBU), and Weight Distribution Indexes (WDI) and stability scores (SS) were measured using a balance measuring unit. [Results] As the thickness of the Tra increased, SLS, DLS, WDI, and SS improved. As SLS improved, DLS and WDI were also improved. [Conclusion] To improve lumbar stability and balance, training is needed in order to increase the muscle mass of the transversus abdominis muscle.
