“…These data are worrying considering that individuals with low levels of lumbar force and frequent back pain 9 are more likely to develop various disorders such as postural deviations 8 , musculoskeletal diseases and excess weight, leading to an increased risk of premature death 11 . In addition, studies on low levels of lumbar force 4 are still scarce, mainly relating sociodemographic factors, economic level and lifestyle.…”

“…Impaired motor control may promote chronicity or recurrent LBP and even be a risk factor for LBP [37,38]. From this perspective, it has been suggested that people with mild deficits of the central nervous system [21], such as an imbalance in recruitment of agonist and antagonist trunk muscles [28,36], slow reaction times [49] or poor proprioception [39], are at risk of developing musculoskeletal disorders. The motor functioning of individuals with LBP is complicated further by the fact that, whereas walking more quickly with impaired coordination may enhance the mechanical instability of the spine, walking more slowly may have considerable disadvantages.…”

Effects of chronic low back pain on trunk coordination and back muscle activity during walking: changes in motor control

et al. 2005

Low back pain (LBP) is often accompanied by changes in gait, such as a decreased (preferred) walking velocity. Previous studies have shown that LBP diminishes the normal velocity-induced transverse counter-rotation between thorax and pelvis, and that it globally affects mean erector spinae (ES) activity. The exact nature and causation of these effects, however, are not well understood. The aim of the present study was to examine in detail the effect of walking velocity on global trunk coordination and ES activity as well as their variability to gain further insights into the effects of non-specific LBP on gait. The study included 19 individuals with non-specific LBP and 14 healthy controls. Gait kinematics and ES activity were recorded during treadmill walking at (1) a self-selected (comfortable) velocity, and (2) sequentially increased velocities from 1.4 up to maximally 7.0 km/h. Pain intensity, fear of movement and disability were measured before the experiment. The angular movements of thorax, lumbar and pelvis were recorded in three dimensions. ES activity was recorded with pairs of surface electrodes. Trunk-pelvis coordination and mean amplitude of ES activity were analyzed. In addition, invariant and variant properties of trunk kinematics and ES activity were studied using principal component analysis (PCA). Comfortable walking velocity was significantly lower in the LBP participants. In the transverse plane, the normal velocity-induced change in pelvis-thorax coordination from more in-phase to more antiphase was diminished in the LBP participants, while lumbar and pelvis rotations were more in-phase compared to the control group. In the frontal plane, intersegmental timing was more variable in the LBP than in the control participants, with additional irregular movements of the thorax. Rotational amplitudes were not significantly different between the LBP and control participants. In the LBP participants, the pattern of ES activity was affected in terms of increased (residual) variability, timing deficits, amplitude modifications and frequency changes. The gait of the LBP participants was characterized by a more rigid and less variable kinematic coordination in the transverse plane, and a less tight and more variable coordination in the frontal plane, accompanied by poorly coordinated activity of the lumbar ES. Pain intensity, fear of movement and disability were all unrelated to the observed changes in coordination, suggesting that the observed changes in trunk coordination and ES activ- Eur Spine J (2006) 15: 23-40

“…The core stability is essential to prevent injuries (10,20) and improve performance in athletes. Weak core muscles may be a risk factor for low back pain (9). Zazulak et al (21) reported that trunk displacement was greater in athletes with knee and ACL injuries compared with uninjured athletes.…”

The purpose of this study was to investigate relationship between core stability, dynamic balance and jumping performance in soccer players. Seventeen male soccer players (mean ± SD: age, 21.06 ± 1.71 years) participated as volunteer in this study. Dynamic balance of the participants were evaluated at directions of anterior (A), posteromedial (PM) and posterolateral (PL) with Star Excursion Balance Test (SEBT). The core stability was evaluated with trunk flexion, side bridge, and trunk extension tests. For jumping performance, squat jump height was measured using a contact mat. There was a negative correlation (r = -0.705) between trunk flexion test and squat jump height (p < 0.002). No significant correlation were identified between trunk flexion, side bridge, trunk extension tests and squat jump height (p > 0.05). There was no significant correlation between trunk flexion, side bridge, trunk extension tests and SEBT values (p > 0.05). The results of this study suggest that trunk flexion is associated with squat jump height in soccer players, but not side bridge and trunk extension tests. The core stability does not contribute significantly on dynamic balance.

Trunk Muscle Weakness as a Risk Factor for Low Back Pain

Abstract: An imbalance in trunk muscle strength, i.e., lower extensor muscle strength than flexor muscle strength, might be one risk factor for low back pain.
