Objective This study aimed to employ nonlinear dynamic approaches to assess trunk dynamic stability with speed, symmetry, and load during repetitive flexion-extension (FE) movements for individuals with and without nonspecific low back pain (NSLBP). Background Repetitive trunk FE movement is a typical work-related LBP risk factor contingent on speed, symmetry, and load. Improper settings/adjustments of these control parameters could undermine the dynamic stability of the trunk, hence leading to low back injuries. The underlying stability mechanisms and associated control impairments during such dynamic movements remain elusive. Method Thirty-eight male volunteers (19 healthy, 19 NSLBP) enrolled in the current study. All participants performed repetitive trunk FE movements at high/low speeds, in symmetric/asymmetric directions, with/without a wearable loaded vest. Trunk instantaneous rotation angle was computed for each trial to be assessed in terms of local and orbital stability, using maximum finite-time Lyapunov exponents (LyEs) and Floquet multipliers (FMs), respectively. Results Both groups demonstrated equivalent competency in terms of trunk control and stability, suggesting functional adaptation strategies may be used by the NSLBP group. Wearing the loaded vest magnified the effects of trunk control impairment for the NSLBP group. The combined presence of high-speed and symmetrical FE movements was associated with least trunk local stability. Conclusion Nonlinear dynamic techniques, particularly LyE, are potentially effective for assessing trunk dynamic stability dysfunction for individuals with NSLBP during various activities. Application This work can be applied toward the development of quantitative personalized spinal evaluation tools with a wide range of potential occupational and clinical applications.

ObjectivesEvaluate the outcomes and explore experiences of patients undergoing a residential combined physical and psychological programme (CPPP) for chronic low back pain.DesignA longitudinal observational cohort design, with a parallel qualitative design using semistructured interviews.SettingResidential, multimodal rehabilitation.Participants136 adults (62 male/74 female) referred to the CPPP, 100 (44 male/56 female) of whom completed the programme, during the term of the study. Ten (2 male/8 female) participated in the qualitative evaluation.InterventionA 3-week residential CPPP.Outcome measuresPrimary outcome measures were the STarT Back screening tool score; pain intensity—11-point Numerical Rating Scale; function—Oswestry Disability Index (ODI); health status/quality of life—EQ-5D-5L EuroQol five-Dimension-five level; anxiety—Generalised Anxiety Disorder-7; depression—Patient Health Questionnaire-9. Secondary outcome measures were the Global Subjective Outcome Scale; National Health Service Friends and Family Test;.ResultsAt discharge, 6 and 12 months follow ups, there were improvements from baseline that were greater than minimum clinically important differences in each of the outcomes (with the sole exception of ODI at discharge). At 12 months, the majority of people considered themselves a lot better (57%) and were extremely likely (86%) to recommend the programme to a friend. The qualitative data showed praise for the residential nature of the intervention and the opportunities for interaction with peers and peer support. There were testimonies of improvements in understanding of pain and how to manage it better. Some participants said they had reduced, or stopped, medication they had been taking to manage their pain.ConclusionsParticipants improved, and maintained long term, beyond minimum clinically important differences on a wide range of outcomes. Participants reported an enhanced ability to self-manage their back pain and support for the residential setting.

Apparent Diffusion

ABSTRACTPain perception, trunk mobility in flexion, extension, and lateral flexion, and apparent diffusion coefficient (ADC) within nucleus pulposus of all lumbar discs were collected before and after posterior-to-anterior mobilization in 16 adults with acute low back pain. ADC was computed from diffusion maps and 3 specific portions of the nucleus pulposus were investigated: anterior (ADCant), middle (ADCmid), and posterior (ADCpost), and their mean as ADCall, a summary measure of ADC within nucleus pulposus. Pain ratings were significantly reduced after mobilization, and mobility of the trunk was significantly increased. Concomitantly, a significant increase in ADCall values was observed. The greatest ADCall changes were observed at the L3-L4 and L4-L5 levels and were mainly explained by changes in ADCant and ADCpost. The simultaneous reduction in pain and increase of water diffusion within nucleus pulposus has has been previously observed in subjects with chronic conditions and exists in the acute phase of the disease. Since the largest changes in ADC were observed at the periphery of the nucleus pulposus, and taken together with pain decrease, our results suggest that increased peripheral random motion of water molecules is implicated in the modulation of the intervertebral disc nociceptive response.

Mckenzie Method

A program utilizing patient response to repeated lumbar movements (including flexion, extension, lateral bending and rotation), known as the McKenzie method, has now been demonstrated to be twice as effective in alleviating low back pain compared to traction and back schools. This is a capsule summary of the “Extrac '86” study as detailed in The Journal of Musculoskeletal Medicine 1987; vol. 4(9):27–34 and 4(12):63–74.

AbstractBackgroundMovement alterations due to low back pain (LBP) could lead to long-term adverse consequences if they do not resolve after symptom subsides. This study aims to determine if altered trunk control associated with recurrent low back pain persists beyond symptom duration.MethodsTwenty young adults with recurrent low back pain were tested once during an LBP episode and once in symptom remission, and twenty matched back-healthy participants served as controls. Participants walked on a treadmill with five prescribed step widths. Motion capture and surface electromyography were used to record frontal plane trunk kinematics and muscle activation. Thorax-pelvis coordination was calculated using vector coding technique, and bilateral longissimus activation and co-activation were analyzed.FindingsYoung adults with recurrent LBP exhibited a “looser” trunk control strategy in the frontal plane during gait that was persistent regardless of pain status across multiple step widths compared to back-healthy controls. This was demonstrated by a greater pelvis-only, less thorax-only coordination pattern, and decreased bilateral longissimus co-activation in individuals with recurrent LBP than controls. The looser trunk control strategy was further amplified when individuals with recurrent LBP were in symptom remission and exhibited greater trunk excursion and reduced in-phase coordination.InterpretationThe amplification of aberrant movement during symptom remission may suggest that movement patterns or anatomical factors existing prior to the tested painful episode underlie the altered trunk control in individuals with recurrent LBP. The symptom remission period of recurrent LBP patients may be a critical window into clinical evaluation and treatment.
