Motor control, which relies on constant communication between motor and sensory systems, is crucial for spine posture, stability and movement. Adaptions of motor control occur in low back pain (LBP) while different motor adaption strategies exist across individuals, probably to reduce LBP and risk of injury. However, in some individuals with LBP, adapted motor control strategies might have long-term consequences, such as increased spinal loading that has been linked with degeneration of intervertebral discs and other tissues, potentially maintaining recurrent or chronic LBP. Factors contributing to motor control adaptations in LBP have been extensively studied on the motor output side, but less attention has been paid to changes in sensory input, specifically proprioception. Furthermore, motor cortex reorganization has been linked with chronic and recurrent LBP, but underlying factors are poorly understood. Here, we review current research on behavioral and neural effects of motor control adaptions in LBP. We conclude that back pain-induced disrupted or reduced proprioceptive signaling likely plays a pivotal role in driving long-term changes in the top-down control of the motor system via motor and sensory cortical reorganization. In the outlook of this review, we explore whether motor control adaptations are also important for other (musculoskeletal) pain conditions.

INTRODUCTION: Chronic low back pain has a direct repercussion on the activities of daily living and the alteration of motor control is its main cause. This change leads to instability of the trunk stabilizer systems that control movements. Trunk flexion and extension movements associated with external disturbances may increase the potential for motor control error, resulting in injury and pain. OBJECTIVE: To evaluate and compare the recruitment of the trunk stabilizer muscles, with and without load, in the flexion and extension movements of the trunk. METHODS: Thirty - four sedentary women were evaluated, aged between 30 and 59 years, divided into: low back pain group (LBPG n = 19) and control group (CG n = 15). The protocol consisted of clinical evaluation, pain evaluation, strength test of extensor trunk muscles and trunk flexion and extension tests (TFET). Muscle electromyography in internal oblique (IO), lumbar multifidus (LM), rectus abdominis (RA), external oblique (EO) and lumbar iliacus (LI) were performed simultaneously. Multivariate analysis of variance was used with two-way repeated measurements. RESULTS: LBPG presented a trend of greater recruitment in all muscles and loads evaluated, with muscle activation up to 47% higher when compared to CG. In the intergroup comparison, the global muscles demonstrated a tendency for greater activation in LBPG, with values up to 53% higher when compared to CG, and predominantly high effect size d> 0.80. In the intragroup comparison, the IO, EO, LI and LM muscles of the LBPG presented ascending muscle recruitment with increased load the opposite was seen in the CG, which showed increased activation only in the LI and LM muscles. CONCLUSION: Women with low back pain need more muscle recruitment to remain stable and, in challenging situations, use inefficient strategies.

Persistent low back pain (LBP) is a major health issue, and its treatment remains challenging due to a lack of pathophysiological understanding. A better understanding of LBP pathophysiology has been recognized as a research priority, however research on contributing mechanisms to LBP is often limited by siloed research within different disciplines. Novel cross-disciplinary approaches are necessary to fill important knowledge gaps in LBP research. This becomes particularly apparent when considering new theories about a potential role of changes in movement behavior (motor control) in the development and persistence of LBP. First evidence points toward the existence of different motor control strategy phenotypes, which are suggested to have pain-provoking effects in some individuals driven by interactions between neuroplastic, psychological and biomechanical factors. Yet, these phenotypes and their role in LBP need further validation, which can be systematically tested using an appropriate cross-disciplinary approach. Therefore, we propose a novel approach, connecting methods from neuroscience and biomechanics research including state-of-the-art optical motion capture, musculoskeletal modeling, functional magnetic resonance imaging and assessments of psychological factors. Ultimately, this cross-disciplinary approach might lead to the identification of different motor control strategy phenotypes with the potential to translate into clinical research for better treatment options.

Abstract: Introduction: Ballet dancers often suffer from low back pain. Aim: Low back pain can be reduced by strengthening the core muscles with the help of a special exercise program. Materials and methods: In the study 62 ballet dancer women (average age: 14.89 ± 1.21 years) were included. Intervention group: n = 30 participant, average age: 14.86 ± 1.00 years, control group: n = 32 participant, average age: 14.91 ± 1.37 years. We examined the pain intensity that occurs during training with visual analog scale, the habitual posture with photogrammetry, the abdominal muscle strength with Kraus–Weber test, the static muscle strength of the trunk muscles with core test and the lumbar motor control with leg lowering test. The intervention group did a trunk prevented exercise program during 3 months, and then we examined them again. Results: In the intervention group the intensity of pain significantly decreased (VAS1: p = 0.012; VAS2: p = 0.021), the abdominal muscle strength significantly improved (K–W. B: p=0.025; K–W. C: p<0.001), the static muscle strength of trunk muscles significantly increased (Core-test: p<0.001) and the lumbar motor control significantly improved in both legs (Leg low. R.: p<0.001; Leg low. L.: p<0.001). Also, the habitual posture greatly improved (frontal view: 34.78%, side view: 52.17%). Conclusion: In ballet dancers with a special exercise program, which improves the conditions of trunk muscles, the motor control of lumbar regions can be improved and the lower back pain and the incidence of injuries can be reduced.

Abstract Background: This study aimed to review studies investigating the effects of motor control training (MCT) on the morphometry of trunk muscles (measured by ultrasound imaging; USI) and pain/or disability in individuals with chronic low back pain (CLBP).Method: PubMed, Web of Science, Scopus, and Cochrane Library databases were searched from inception until January 2020. Randomized control trials (RCTs) which included measurements of both muscle morphometry using USI and assessments of pain or disability in individuals with CLBP were included. Study selection, data extraction and quality assessment were done by two reviewers independently. Modified Downs and Black tool and grading of recommendations assessment, development, and evaluation tool were used to assess risk of bias and quality of evidence, respectively. A meta-analysis was performed using a random-effects model with mean difference (MD) or standardized mean difference (SMD). Results: Fifteen RCTs were included. The results revealed that there were no differences in the size (thickness) of the transversus abdominis (TrA), internal and external oblique, and lumbar multifidus muscles in studies which did and did not include MCT interventions. However, the contraction ratio for the TrA muscle was greater in response to MCT, with a high effect size (SMD= 0.93 CI: - 0.0 to 1.85). Pain (visual analogue scale, MD=1.00, 95%CI -1.77 to -0.24) and disability (SMD=-0.55, 95% CI: -0.94 to -0.16) scores were lower in the groups who underwent MCT compared with other interventions, with moderate and low effect sizes.Conclusions: MCT interventions were superior to other interventions for measures of TrA muscle function. Despite changes in pain and disability following MCT interventions, corresponding changes in trunk muscle morphometry (evaluated using thickness measures) were not evident. This could be due to the effect of other factors such as psychosocial factors that impact the clinical outcomes for those with CLBP.Systematic review registration: PROSPERO: CRD42019144768
