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.

Introduction. - This study used an iso-inertial dynamometer to investigate the influence of counter-movement and barbell throwing during bench press exercise. A critical analysis of these modalities during muscular evaluation was also performed. Methods. - The action of muscle stretch during the counter-movement induced an increase in average velocity and a shortening of the time to reach the peak power and peak velocity. The barbell throwing did not alter the initial part of the movement yet lengthened the propulsive phase and delayed the braking phase. Consequently, maximal power and maximal velocity performances were improved. However, the throwing of the barbell requires its catch when failing down, which could be potentially harmful. Conclusion. - The counter-movement and the throwing of the barbell significantly change the iso-inertial performances through a bench press exercise. The modalities of bench press assessment execution would have to be rigorously standardized. (c) 2006 Elsevier SAS. Tous droits reserves. [less ▲]

Sports activity involving the upper limb implies some powerful movements leading to the development of specific adaptations of the shoulder. These adaptive patterns increase the risk of injury. Shoulder rehabilitation in athletes should be guided by the results of a specific physical examination of the shoulder. In this article we propose an original evaluative form specifically designed for the athletic shoulder which takes into consideration the morphostatic and physical features as well as the possible bilateral asymmetries. The functional evaluation includes measurement of range of motion, flexibility, isometric muscle strength, position and motion patterns of the scapula. Progress achieved during rehabilitation programs can be monitored with successive evaluations which are helpful for determining the most suitable treatment. [less ▲]

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 ▲]

The purpose of this study was to investigate the reproducibility of findings derived from a new iso-inertial dynamometer during bench press (BP) and squat (SQ) and to provide descriptive data for recreational athletes. A position transducer and accelerometer were combined to assess velocity and power during free weight lifting exercises. Simulated movement with a pulley system revealed the excellent technical consistency of the dynamometer. Sixteen male subjects participated in the study. Iso-inertial tests consisted of lifting as fast as possible four different relative loads (35, 50, 70, 90% 1RM in BP and 45, 60, 75, 90% 1RM in SQ). The test was repeated one week later. Analysis of variance revealed no significant variation between sessions or trials. Reproducibility was better in velocity than in power, although it remained fairly good in both exercises (coefficients of variation [CV] never exceeding 10%) except for the time to peak power parameter. Descriptive data confirmed the classical force-velocity and force-power relationships for BP and SQ. In conclusion, this study demonstrated reliable measurements in BP and SQ iso-inertial exercises. Monitoring force-velocity and force-power relationships offers an original functional approach in strength training supervision. [less ▲]

Objectif : Ce travail a pour objectif d’apprécier l’intérêt d’un programme de reconditionnement physique aérobie dans le traitement de la fibromyalgie. Patients et méthodes : Dix patientes fibromyalgiques, diagnostiquées selon les critères du Collège Américain de Rhumatologie (1990), réalisent trois séances hebdomadaires d’une durée d’une heure trente sur une période de 3 mois. Le programme de revalidation comporte principalement des activités musculaires aérobies (bicyclette ergométrique, tapis de marche, rameur et step), complétées par des étirements et de la relaxation. Les bénéfices éventuels sont objectivés à partir d’épreuves physiques maximales (isocinétisme) et sous-maximales (test de marche, bicyclette ergométrique, endurance musculaire statique), d’une évaluation du seuil de sensibilité douloureuse à l’aide d’un dolorimètre et de questionnaires de qualité de vie, de quantification de la fatigue et de satisfaction. En outre, les perceptions douloureuses et de pénibilité de l’effort sont respectivement quantifiées à partir des échelles visuelle analogique (EVA) et de Borg. Résultats : Au terme de cette revalidation, une amélioration significative de tous les paramètres physiques est objectivée. Les performances s’améliorent de 26 % lors de l’épreuve de force isocinétique maximale réalisée au niveau des muscles fléchisseurs et extenseurs de genou, de 43 % lors des épreuves isométriques sous-maximales prolongées, de 42 % lors de l’épreuve ergométrique et de 17 % lors de l’épreuve de marche. Ces bénéfices s’accompagnent d’une réduction systématique des perceptions douloureuses et de la difficulté de l’effort mais aussi d’un accroissement du seuil de sensibilité douloureuse. Les questionnaires de qualité de vie et de quantification de la fatigue confirment l’amélioration fonctionnelle. Le programme répond effectivement aux attentes des fibromyalgiques, comme le démontrent les scores du questionnaire de satisfaction. Discussion : Cette option thérapeutique de revalidation se justifie d’autant plus que la faiblesse des qualités musculaires du fibromyalgique a déjà été soulignée. Cette rééducation devrait idéalement se compléter par diverses interventions comme le soutien psychologique et les stratégies cognitivo-comportementales. Conclusion : Cette étude confirme l’intérêt d’un programme de revalidation musculaire progressive dans le cadre de la prise en charge rééducative de la fibromyalgie. Un tel programme réduit les répercussions physiques et psychologiques défavorables de l’affection. [less ▲]

Introduction : La fibromyalgie et la lombalgie constituent deux affections musculo-squelettiques chroniques présentant de nombreuses similitudes, comme la douleur, la régression des activités physiques quotidiennes ou encore la désinsertion sociale. L’objectif de ce travail était de comparer des patients fibromyalgiques et des patients souffrant de lombalgies chroniques en termes de qualités musculaires à partir de mesures de force et de fatigabilité musculaires. Patients et méthodes : Vingt sujets contrôles de sexe féminin, vingt patientes fibromyalgiques et vingt patientes souffrant de lombalgies chroniques sont inclus dans l’étude. Le protocole comporte une évaluation de la force maximale isocinétique des muscles fléchisseurs et extenseurs de genou. La résistance musculaire à la fatigue s’apprécie par l’enchaînement de 30 mouvements consécutifs de flexion-extension de genou à intensité maximale. Les perceptions douloureuses et de pénibilité de l’effort sont respectivement mesurées à partir des échelles visuelle analogique (EVA) et de Borg. En outre, l’anxiété et la dépression sont déterminées à partir de l’ « Hospital Anxiety and Depression Scale » (HAD). Résultats : L’ensemble des performances de force et de fatigabilité apparaissent inférieures chez les fibromyalgiques, en comparaison non seulement des sujets contrôles mais aussi des patientes lombalgiques. Ces dernières développent des performances identiques à celles de la population contrôle. Les scores douloureux (EVA) et de pénibilité de l’effort apparaissent pourtant significativement augmentés au sein de ces deux populations pathologiques. Les questionnaires d’anxiété et de dépression (HAD) révèlent des scores significativement supérieurs chez les fibromyalgiques. Discussion : Ces résultats illustrent un profil musculaire différent entre populations fibromyalgique et lombalgique. La réduction majeure des performances développées par les patientes fibromyalgiques peut être mise en relation avec l’état de déconditionnement, les scores d’anxiété et de dépression, la douleur diffuse et d’éventuels mécanismes d’inhibition musculaire. Contrairement à certaines données de la littérature, nous observons des performances musculaires des membres inférieurs relativement préservées chez les patientes lombalgiques. Conclusion : Au terme de cette étude comparative entre populations souffrant de douleurs chroniques, nous démontrons de faibles performances musculaires développées par les membres inférieurs chez les sujets fibromyalgiques. Une mesure des qualités musculaires rachidiennes peut s’avérer plus spécifique dans l’établissement du profil musculaire du lombalgique. [less ▲]

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 ▲]
