Les patients lombalgiques présentant une instabilité lombaire semblent constituer un sous-groupe particulier. De nombreuses définitions de l’instabilité lombaire ont été proposées. L’instabilité radiologique se distingue de l’instabilité fonctionnelle. Leur diagnostic demeure délicat : l’intérêt des clichés radiographiques statique et dynamique semble limité tandis que plusieurs signes et tests cliniques de l’instabilité ont été décrits dans la littérature mais demeurent controversés. Trois éléments composent le système de stabilisation fonctionnelle de la colonne : les sous-systèmes passif, actif et neuromusculaire qui sont interdépendants. L’intérêt de programmes de stabilisation lombaire pour les patients lombalgiques a été démontré. Les exercices de stabilisation lombaire visent une reprogrammation sensorimotrice des muscles stabilisateurs de la colonne afin d’améliorer leur potentiel, leur temps de réponse et ainsi compenser des déficits du système passif de stabilisation. Cet article souhaite définir le concept d’instabilité, préciser les moyens de son évaluation, appréhender les anomalies du système de stabilisation présentes chez les sujets lombalgiques, décrire les principaux exercices recommandés dans la littérature et enfin rapporter les bénéfices observés à la suite de programmes de stabilisation lombaire.

This article reviews available techniques for spinal muscle investigation, as well as data on spinal muscles in healthy individuals and in patients with low back pain. In patients with chronic low back pain, medical imaging studies show paraspinal muscle wasting with reductions in cross-sectional surface area and fiber density. In healthy individuals, the paraspinal muscles contain a high proportion of slow-twitch fibers (Type I), reflecting their role in maintaining posture. The proportion of Type I fibers is higher in females, leading to better adaptation to aerobic exertion compared to males. Abnormalities seen in paraspinal muscles from patients with chronic low back pain include marked Type II fiber atrophy, conversion of Type I to Type II fibers, and an increased number of nonspecific abnormalities. Limited data are available from magnetic resonance spectroscopy used to investigate muscle metabolism and from near infrared spectroscopy used to measure oxygen uptake by the paraspinal muscles. Surface electromyography in patients with chronic low back pain shows increased paraspinal muscle fatigability, often with abolition of the flexion-relaxation phenomenon. [less ▲]

Cet article présente les différentes techniques d’investigation de la musculature rachidienne et analyse les données relatives aux muscles spinaux de sujets sains et lombalgiques chroniques. L’atrophie des muscles paravertébraux de lombalgiques chroniques et notamment une réduction de leur surface de section et de leur densité musculaire peuvent être objectivées par l’imagerie médicale. La biopsie musculaire des muscles spinaux de sujets sains démontre un pourcentage élevé de fibres lentes (type I) lié à leur fonction posturale ; les femmes se caractérisent par une meilleure adaptation à l’effort aérobie s’expliquant par une plus grande section musculaire relative occupée par les fibres de type I. Les muscles spinaux de lombalgiques chroniques présentent soit une atrophie marquée des fibres de type II, soit une conversion des fibres de type I en type II, soit la présence accrue d’anomalies non-spécifiques. La spectroscopie par résonance magnétique et en proche infrarouge, explorant respectivement le métabolisme musculaire et l’oxygénation tissulaire de la musculature spinale, restent encore peu décrites. L’électromyographie de surface confirme, chez les lombalgiques chroniques, la fatigabilité accrue des muscles spinaux et l’absence fréquente du phénomène de flexion–relaxation. [less ▲]

Background: Fibromyalgia (FM) is defined as a chronic syndrome characterized by diffuse pain. FM patients generally complain of muscle fatigue during physical activities and symptoms worsening after exercise. Some studies have explored muscle performances in FM patients. Similarly, we reported that all variables of muscle performances were decreased in FM patients as compared to the controls [1]. We found that muscle impairment predominated over aerobic processes. The 31P nuclear magnetic resonance spectroscopy (NMRS) appears especially useful to study muscle energy metabolism because it is non-invasive and allows the exploration during exercise. Objectives: The purposes were: (1) to determine the maximal transverse section (MTS) of calf muscles by Magnetic Resonance Imaging (MRI) in order to calculate the individual mechanical loads of exercise without requiring the measurement of the maximal voluntary torque; (2) to monitor, by 31P-NMRS, high-energy phosphate metabolism and intracellular pH at rest, during exercise and recovery periods by means of continuous spectra acquisitions with an adequate temporal resolution; (3) to determine an original efficacy muscular index with the help of the ergometric and spectroscopic parameters; (4) to explore the oxidative pathway by means of determination of the PCr rephosphorylation time constant. Methods: Eight women with fibromyalgia (FM) and 30 healthy volunteers were included in this study. MRI of the dominant leg was acquired in order to determine the MTS of calf muscles and thus to calculate the different loads of exercise (dynamic plantar flexions). Subjects performed 3-6 bouts of 2 minutes with workload increments until exhaustion. Spectra were acquired continuously at rest, during the exercise and recovery periods. The analysis concerned the gamma-, alpha- and beta- ATP, Pi, PCr peaks, and intracellular pH. At the end of the exercise, the muscular efficacy index and the PCr re-phosphorylation time constant were calculated. Results: The MTS of the ankle plantar flexors reached respectively 43 cm² and 36.7 cm² in the control and FM groups (p > 0.05). No significant difference (p > 0.05) was observed between both groups in spectroscopic data registered at rest [10.7 (control) vs 9.1 (FM) for PCr/Pi rest ; 7.01 (control) vs 6.99 (FM) for pHrest] and at the end of exercise [1.18 (control) vs 0.68 (FM) for PCr/Pi end ; 6.89 (control) vs 6.81 (FM) for pHend]. However, the muscular efficacy index was significantly reduced in FM patients (1.25) in comparison with control group (2.46) (p < 0.05). Two patients presented an index extremely low (0.3 and 0.4). The PCr time constant was not different between control subjects (27.7 s) and FM patients (25.6 s) (p > 0.05). Conclusion: Our original protocol, not based on maximum voluntary contraction assessment, did not indicate any abnormalities in glycolytic and oxydative pathways in FM patients. We demonstrated a low efficiency of chemical to mechanical energy shift in FM patients. These results suggested a deconditioning syndrome without primitive muscular abnormalities in FM patients and displayed the importance of aerobic muscular rehabilitation.

Neuromuscular electrical stimulation (ES) and passive recovery (PR) were compared in ten healthy men after a provocation exercise inducing delayed onset of muscle soreness (DOMS). The exercise consisted of 3 sets of 30 maximal eccentric contractions performed by the knee flexor muscles of the dominant leg on an isokinetic dynamometer at 60 degrees/s angular velocity. There was an interval of 8 weeks between both bouts and the order of the recovery mode (ES or PR) was block-randomly assigned. ES recovery consisted of a 25-min continuous and non-tetanic (5 Hz) stimulation of the hamstring muscles. Concentric and eccentric hamstrings peak torques were evaluated before and immediately after the provocation exercise, after the recovery period, as well as 24 h (d1), 48 h (d2), 72 h (0) and 168 h (0) after the bout. Subjective perception of muscle soreness (VAS, 0-10 a.u.) was evaluated before exercise and at d1, d2, 0 and d7. To assess the CK activity, five blood samples were drawn before exercise and at d1, d2, d3 and d7. For both recovery modes, the greatest reductions in isokinefic muscle performances were measured on d2 (66.3 +/- 24.1 % of initial values (ES) vs. 57.4 +/- 26.5% (PR) for the concentric mode and 55.6 +/- 16% (ES) vs. 53.1 +/- 19.3% (PR) for the eccentric mode). d2 also corresponded to the highest painful sensations (5.4 +/- 2.14 a.u. (ES) vs. 6.15 +/- 2.55 a.u. (PR)). Peak activities of CK were reached on d3 (47507 +/- 19973 IU/l (ES) vs. 75887 41962 IU/l (PR)). Serum CK was lower with ES than PR at 0 (p <= 0.05) but all other parameters changed in a manner that was not statistically different between the two recovery protocols (p > 0.05). This strong trend could be explained by an electro-induced hyperperfusion that may efficiently wash out the muscle from the cellular debris resulting from the initial injury, and hence diminish the inflammatory response and the delayed amplification of tissue damages.

Objectives: Compare a treatment combining a back school program and physical training with a treatment consisting of only aback school program undertaken by chronic low back pain [CLBP] patients. Methods: Forty CLBP patients [21 females] completed an educational back school program. Once ended, 17 subjects [the Education-Physical Group [EPG]] started physical training sessions attended twice a week [90 minutes] for six weeks. The others constituted the Education Group [EG]. All subjects performed three tests: the pain visual analog scale, the Dallas questionnaire assessing quality of life, and an ergonomic test at the beginning [Day [D] 1], at the end [D21] of the back school program, and three months later [D120]. The EPG also carried out physical tests at the start and at the end of the physical training. Results: At D21, no significant difference in pain and Dallas scores appeared, although patients of both groups performed the ergonomic test significantly better. At D120, the decrease of pain intensity and the quality of life improvement were significant in both groups [P < 0.05]. The extent of the pain intensity decrease was significantly higher in the EPG compared to the EG. The EPG displayed improvements in most physical assessments [P < 0.05]. Only the increase of knee extensors strength correlated significantly with the improvements of quality of life and ergonomic function scores. Conclusions: This study supports positive effects of a back school program for CLBP patients. Additional physical training sessions lead to lower pain intensity, greater improvement of quality of life than back school sessions only, as well as improvement of muscle performances. The increase of the knee extensors strength might have helped to decrease the pain and improve the quality of life. [less ▲]

La première épreuve d’évaluation de l’endurance isométrique des muscles extenseurs du tronc a été décrite par Hansen dès 1964. En 1984, suite à l’étude de Biering-Sorensen, ce test a été largement diffusé dans la littérature sous le nom de « test de Sorensen ». Sa notoriété résulte de son prétendu caractère prédictif de l’occurrence, chez les sujets masculins, d’une lombalgie au cours de l’année à venir. Il s’effectue en décubitus ventral avec le tronc en débord de table, les membres inférieurs étant fixés ; dans cette position le sujet doit maintenir le plus longtemps possible son tronc à l’horizontale. Ce test a été utilisé dans de nombreuses études, de façon standardisée ou modifiée. Il semble discriminatif, reproductible et sans danger, mais les avis divergent toujours dans sa capacité à prédire l’apparition d’une lombalgie, de la présence d’une différence intersexuelle et de l’influence du poids corporel sur le temps de maintien. Si la participation des muscles extenseurs de hanche ne fait plus de doute, leur contribution exacte demeure inconnue. L’influence de facteurs individuels (tel que la motivation) constitue toujours un élément limitant l’interprétation des résultats. Malgré ces inconvénients, le test de Sorensen s’est imposé comme un outil de référence pour apprécier les performances musculaires du patient lombalgique et leur évolution suite à un programme de réhabilitation.

The first test for evaluating the isometric endurance of trunk extensor muscles was described by Hansen in 1964. In 1984, following a study by Biering-Sorensen, this test became known as the “Sorensen test” and gained considerable popularity as a tool reported to predict low back pain within the next year in males. The test consists in measuring the amount of time a person can hold the unsupported upper body in a horizontal prone position with the lower body fixed to the examining table. This test has been used in many studies, either in its original version or as variants. Although its discriminative validity, reproducibility, and safety seem good, debate continues to surround its ability to predict low back pain; in addition, the gender-related difference in position-holding time remains unexplained and the influence of body weight unclear. A contribution of the hip extensor muscles to position holding has been established, but its magnitude remains unknown. The influence of personal factors such as motivation complicates the interpretation of the results. Despite these drawbacks, the Sorensen test has become the tool of reference for evaluating muscle performance in patients with low back pain, most notably before and after rehabilitation programs.

The purpose of this study was to investigate the inter-session, inter-tester and inter-site reproducibility of trunk muscle strength scores in flexion, extension, lateral flexion and rotation. Ten healthy students were tested on four apparatus with a 7-10 day break between sessions. The first two sessions were identical while the other two differed either by the tester or by the site. Furthermore, 10 patients with chronic low back dysfunction (CLBD) were assessed with the four apparatus, once only. For all tests, CV ranged from 3.4% to 7.6% and from 3.9% to 8.1% in the inter-session and inter-tester studies, respectively (p > 0.05 except for inter-session reproducibility of trunk flexor strength). Peak torque (PT) was more variable from site to site with a CV ranging from 4.2% to 12.7%, particularly in extension and left lateral flexion (p < 0.05). No statistically significant difference in the strength ratios (flexion/extension, right/left lateral-flexion and right/left rotation) were found between sessions or testers (4.9% < CV < 9.7%). The inter-site reproducibility of ratios was lower. Comparison between the CLBD patients and the healthy subjects with regard to PT normalized to body weight indicated significantly decreased performance for the former except for flexion and rotation scores in males. We conclude that in the case of healthy subjects, inter-session and inter-tester trunk strength measurements derived from these devices are reproducible. The low inter-site reproducibility suggests that caution should be exercised when interpreting findings originating from different sites. The lower extension strength scores in CLBD patients test lends some validity to the system. However, further studies focusing on reproducibility and validity of this system in CLBD patients are critical before any conclusion regarding their clinical viability may be drawn. [less ▲]

This article aims to recommend easy, reproducible and valid physical tests and questionnaires to allow a functional and physical assessment of sub-acute and chronic low back pain patients. We recommend the pain visual analogue scale, the French translation of the Roland-Morris Disability Questionnaire (EIFEL) and the Dallas questionnaire to appreciate pain intensity and its influence on patients' quality of life. Sorensen's test is recommended in order to assess trunk extensor muscles endurance. We suggest to measure pelvic and lumbar flexion mobility by means of the inclinometer technique. The test described by McQuade is recommended to assess abdominal muscles static endurance. [less ▲]
