Objectives: The aim of this study was to use magnetic resonance imaging and 31P spectroscopy in order to explore muscle metabolism during exercise in fibromyalgia patients. Methods: Eight women with fibromyalgia (FM) and 30 healthy volunteers were included in this study. Magnetic resonance imaging of the dominant leg was acquired in order to determine the maximal transverse section (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 -, - and - ATP, Pi, PCr peaks, and intracellular pH. At the end of the exercise, a muscular efficacy index and the PCr re-phosphorylation time constant were calculated. Results: The MTS of the ankle plantar flexors reached respectively 43  7 cm² and 36.7  5 cm² in 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/Pirest ; 7.01 (control) vs 6.99 (FM) for pHrest] and at the end of exercise [1.18 (control) vs 0.68 (FM) for PCr/Piend ; 6.89 (control) vs 6.81 (FM) for pHend]. The muscular efficacy index was significantly reduced in FM patients (1.25) in comparison with control group (2.46) (p < 0.05). The PCr time constant was not different between control subjects (27.7 s) and FM patients (25.6 s) (p > 0.05). Conclusions: This study 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. [less ▲]

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 ▲]

Skeletal muscle voluntary contractions (VC) and electrical stimulations (ES) were compared in eight healthy men. High-energy phosphates and myoglobin oxygenation were simultaneously monitored in the quadriceps by interleaved H-1- and P-31-NMR spectroscopy. For the VC protocol, subjects performed five or six bouts of 5 min with a workload increment of 10% of maximal voluntary torque (MVT) at each step. The ES protocol consisted of a 13-min exercise with a load corresponding to 10% MVT. For both protocols, exercise consisted of 6-s isometric contractions and 6-s rest cycles. For an identical mechanical level (10% MVT), ES induced larger changes than VC in the P-i-to-phosphocreatine ratio [1.38 +/- 1.14 (ES) vs. 0.13 +/- 0.04 (VC)], pH [6.69 +/- 0.11 (ES) vs. 7.04 +/- 0.07 (VC)] and myoglobin desaturation [43 +/- 15.9 (ES) vs. 6.1 +/- 4.6% (VC)]. ES activated the muscle facing the NMR coil to a greater extent than did VCs when evaluated under identical technical conditions. This metabolic pattern can be interpreted in terms of specific temporal and spatial muscle cell recruitment. Furthermore, at identical levels of energy charge, the muscle was more acidotic and cytoplasm appeared more oxygenated during ES than during VC. These results are in accordance with a preferential recruitment of type II fibers and a relative muscle hyperperfusion during ES. [less ▲]

Delayed onset muscle soreness (DOMS) follows unaccustomed muscular exercise, most notably in the eccentric mode. That concept refers to a dull ache combined with tenderness, stiffness and weakness of the previously active muscles. lsokinetic device constitutes a specific model in generating and investigating DOMS. Respective effects of concentric and eccentric actions have been compared, emphasizing on the variability in the response (serum activity of CK for instance). The particular sensitivity of the hamstrings was underlined although causes remained unexplained. Some treatment have been proposed in the management of DOMS. Several studies reported that anti-inflammatory agents fail to alleviate pain and discomfort even if other authors indicated a relative effectiveness. Based on the repeated-bout effect, submaximal eccentric exercise currently represent the most useful preventive strategy. [less ▲]
