Introduction: Lumbar pain among athletes is a common problem and can be challenging for athletic trainers and therapists. Unfortunately, little is known about the capabilities of trunk muscle function in elite athletes Therefore, an objective assessment of muscle performance is relevant in injury prevention and rehabilitation. The purpose of this study was to examine the specific trunk muscle strength and endurance in different sports i.e. swimming, rowing and tennis. Methods: We assessed maximum isometric trunk extensor, rotator, flexor and lateroflexor muscle strength as well as trunk extensor muscle endurance of 10 swimmers, 10 rowers, 10 tennismen and 10 sedentary students (control group). Strength was measured by means of specific trunk dynamometers. An adaptation of the Sorensen test was performed to assess trunk extensor endurance. Results: Muscle strength appeared generally higher among athletes than among control subjects. However, differences were statistically significant only with swimmers for trunk flexors (p<0.05) and trunk rotators (p<0.05), with rowers for trunk flexors (p<0.05) and with tennismen for dominant lateroflexors (p<0.05) and non-dominant trunk rotators (p<0.05). No significant bilateral difference appeared for trunk lateralflexors strength. For trunk rotators, tennismen were significantly stronger in the non-dominant side (p<0.05). Trunk extensor endurance was higher among rowers than among the other groups. Conclusion: This study underlined several differences in trunk muscle performance between athletes and control subjects as well as within athletes groups in relation to their sports. Further studies would clarify the full significance of these results with respect to performance and injury. [less ▲]

The purpose of this study was to compare an electrostimulated to an active recovery strategy after a submaximal isometric fatiguing exercise. Nineteen healthy men completed three sessions (separated by at least 4 weeks) which included a knee extensors provocation exercise consisting of 3 sets of 25 isometric contractions. Contraction intensity level was fixed respectively at 60%, 55% and 50% of previously determined maximal voluntary contraction for the first, second and third sets. This provocation exercise was followed by either an active (AR) recovery (25 min pedaling on a cycle ergometer), an electrostimulated (ESR) recovery (25-min continuous and nontetanic (5 Hz) stimulation of the quadriceps) or a strictly passive recovery (PR). Peak torques of knee extensors and subjective perception of muscle pain (VAS, 0-10) were evaluated before (pre-ex), immediately after the provocation exercise (post-ex), after the recovery period (post-rec), as well as 75 minutes (1h15) and one day (24h) after the exercise bout. Time course of peak torque was similar among the different recovery modes: ~ 75% of initial values at post-ex, ~ 90% at post-rec and at 1h15. At 24h, peak torque reached a level close to baseline values (PR: 99.1 ± 10.7%, AR: 105.3 ± 12.2%, ESR: 104.4 ± 10.5%). VAS muscle pain scores decreased rapidly between post-ex and postrec (p < 0.001); there were no significant differences between the three recovery modes (p = 0.64). In conclusion, following a submaximal isometric knee extension exercise, neither electrostimulated nor active recovery strategies significantly improved the time course of muscle function recovery.

Objectives: To evaluate the efficacy of a semi-intensive multidisciplinary outpatient program complying with the requirements of the Belgian National Institute for Health and Disability Insurance and intended for patients with chronic low back pain. Methods: Weincluded 262 patients with nonspecific chronic low back pain, amongwhom136 (73women and 63 men) with a mean pain duration of 11.3 years completed the outpatient program (36 sessions each lasting 2 h). The program consisted of education about back-sparing techniques, interventions by an occupational therapist and psychologist, and physical reconditioning. Three sessions (sessions 1, 18, and 36) were used to evaluate pain intensity, functional impairment, kinesiophobia, cognitive knowledge, knowledge of appropriate spinal movement technique, and physical performance (trunk muscle strength and endurance, mobility of the pelvis and lumbar spine, and aerobic capacity). Results: All study variables were significantly improved at study completion compared to baseline: pain intensity was decreased by 44%, functional impairment by 40%, and kinesiophobia by 11% whereas knowledge was improved by 59%, back-sparing technique by 95%, trunk muscle strength by 40% on average, trunk extensor muscle endurance by 90%, mobility by 8%, and aerobic capacity by 18%. Conclusions: A semi-intensive multidisciplinary outpatient program was beneficial in patients with chronic low back pain. Careful patient selection and increased patient involvement in the program may help to improve adherence. [less ▲]

Objectifs. – Cette étude souhaite apprécier l’efficacité d’un programme pluridisciplinaire ambulatoire semi-intensif, élaboré en fonction des exigences des organismes mutualistes belges et destiné aux patients lombalgiques chroniques. Méthodes. – Parmi 262 patients souffrant de lombalgie chronique non spécifique inclus dans cette étude, 136 (73 femmes et 63hommes présentant des douleurs depuis 11,3 ans en moyenne) ont achevé un programme ambulatoire (36 séances de deux heures) comportant une éducation à l’économie rachidienne, une approche ergonomique et psychologique ainsi que des séances de reconditionnement physique. Trois séances (initiale [séance 1], intermédiaire (séance 18) et finale [séance 36]) évaluent les paramètres d’intensité de la douleur, d’incapacité fonctionnelle, de kinésiophobie, de connaissances cognitives et gestuelles ainsi que les performances physiques (force et endurance des muscles du tronc, mobilité du complexe lombo-pelvi-fémoral, endurance cardiorespiratoire). Résultats. – Tous les paramètres sont significativement améliorés lors de l’évaluation finale : diminution de l’intensité de la douleur (−44 %), des répercussions fonctionnelles (−40 %) et de la kinésiophobie (−11 %), amélioration des connaissances (+59 %) et de la gestuelle vertébrale (+95 %), augmentation de la force des muscles du tronc (+40 % en moyenne), de l’endurance des extenseurs du tronc (+90 %), de la mobilité (+8 %) et de l’endurance cardiorespiratoire (+18 %). Conclusions. – Une prise en charge pluridisciplinaire ambulatoire semi-intensive s’avère bénéfique pour les patients lombalgiques chroniques. Une adaptation des critères d’inclusion et une implication accrue du patient dans sa rééducation contribueraient à améliorer l’observance du programme. [less ▲]

Purpose. Firstly, to examine whether heart rate (HR) can be predicted based on the Borg-scale for perceived exertion in patients with chronic low back pain (CLBP) and secondly, to assess changes in HR, Borg-scores and workload to study the relevance of a stepwise increase of workload based on the Borg-score and HR. Methods. Ninety-nine patients with CLBP and a mean disability-score (Roland Morris Disability Questionnaire) of 13.8 (SD = 3.7) participated in a 10-week aerobic training programme (20 min, 3 times/week). HR, ratings of perceived exertion (RPE), and workload were monitored. Prior to treatment, patients completed questionnaires on pain, disability, and several psychological factors (catastrophizing, kinesiophobia, and depression). Results. The original Borg-equation (i.e. 'HR = Borg x 10') appears accurate in predicting HR on a group-level. Pain-related and psychological factors were not significantly related to the accuracy of the Borg equation. Whereas mean workload increased significantly (from 93.8 (SD = 29.9) to 129.5 W (SD = 39.7), p < 0.001) throughout the training programme, HR increased only slightly (from 130.2 (SD = 13.5) to 139.2 (SD = 13.9) bpm; p < 0.001) and Borg-scores remained stable (from 13.2 (SD = 1.9) to 13.3 (SD = 1.8); p = 0.48). Conclusions. The capability of the Borg-scale to accurately predict HR appears moderate. However combined with measuring HR, it results in a relevant and efficient method for training CLBP patients in clinical practice. [less ▲]

Background and Aims: Literature describes several dynamometric and non-dynamometric tests to assess trunk extensor muscle performances. In patients with chronic low back pain (CLBP), reproducibility of such assessments remains understudied. The purpose of this study was to compare reproducibility of two dynamometric tests and of the widely used Sorensen test. Methods: 44 patients (22 men, 22 women; age range: 30-60 years) with CLBP (mean Roland-Morris disability scores reaching 6 ± 3.4) were randomized into two groups attending two assessment sessions. Group 1 (12 men and 12 women) underwent two tests (i.e. a maximal strength test (figure 1) and a static endurance test requiring to maintain as long as possible a torque of 50 percent of maximal strength previously determined (figure 2)) performed on a specific trunk extensor dynamometer (David Back). Group 2 (10 men and 10 women) was submitted to the non-dynamometric Sorensen test (lifting the upper trunk and maintaining the horizontal position) (figure 3). For both groups, tests were performed twice (spaced by 15 minutes) during the first session (intra-session reproducibility) and once during the second session (inter-session reproducibility) happening 2 to 7 days later. Results: Mean torques reached 2.67 ± 0.63 Nm/Kg (women) and 3.66 ± 0.75 Nm/Kg (men) for the strength test. Mean maintaining times were 83 ± 34 s for the endurance test and 99 ± 28 s for the Sorensen test. The Table presents coefficient of variations (CV) and limits of agreement (LOA) related to the intra-session and inter-session reproducibility. Conclusions: Reproducibility appeared satisfactory for the strength test, moderate for the Sorensen test and low for the dynamometric endurance test in patients with moderate CLBP. [less ▲]

Introduction Treatment or training sessions with neuromuscular electrical stimulations (NMES) are generally performed in a transcutaneous manner with the aid of surface electrodes. Several investigators have highlighted the benefits of quadriceps stimulation during rehabilitation following traumatic injury or surgery of the knee and during physical preparation of athletes (Kramer and Mendryyk, 1982). However, the practical modalities of quadriceps stimulation (number, size and localization of electrodes) remain controversial (Vanderthommen and Duchateau, 2007). The present work aimed to determine the optimal electrodes setting for NMES applied to the quadriceps. Methods Twenty physically active men (23 ± 2 years, 180 ± 8 cm, 75 ± 12 Kg) underwent first an evaluation of left quadriceps maximal isometric voluntary torque (QMIVT). The exact localization of the motor points of vastus medialis (MPVM) and vastus lateralis (MPVL) was also determined. Then, we tested unilaterally, isometrically and consecutively five electrodes settings (ES) including rectangular (10 x 5 cm) (RE) or square (5 x 5 cm) (SE) electrodes, with identical stimulation parameters (biphasic symmetric rectangular pulses, 80 Hz, pulse duration 0.35 ms, constant current intensity (42 ± 11 mA)): ES1= 1 channel, 2 RE transversally on the thigh (with the distal electrode placed on MPVM and MPVL); ES2= 1 channel, 2 RE longitudinally on MPVM and MPVL; ES3= 1 channel, 2 SE on MPVM and MPVL; ES4= 2 channels, 4 SE (with 2 SE placed on MPVM and MPVL); ES5= 2 channels, channel 1= 1 SE on MPVM and 1 RE transversally on the proximal part of the thigh, channel 2= 1 SE on MPVL and 1 RE transversally on the proximal part of the thigh. For each ES we measured the electrostimulated torque. Results The mean QMIVT reached 200 ± 51 Nm. The MPVM and MPVL were situated 10 ± 2 cm and 14 ± 3 from the patellar base, respectively. The stimulated contractions reached 9.2 ± 7.4 Nm (4.6% of QMIVT) for ES1, 8 ± 4.8 Nm (4% of QMIVT) for ES2, 15 ± 8.3 Nm (7.5% of QMIVT) for ES3, 16.3 ± 7.7 Nm (8.2% of QMIVT) for ES4 and 40.4 ± 11.3 Nm (20.2% of QMIVT) for ES5 (p<0.05). Discussion During NMES programs it appears crucial to use a proper electrode setting ensuring efficient muscle recruitment and therefore optimized training effects. However, physiotherapists and trainers often place electrodes empirically especially for NMES applied to the quadriceps. This study demonstrated the relevance of using two channels for quadriceps NMES and of setting, for each channel, one small “excitative” electrode exactly on the motor point of vastus medialis or lateralis and one bigger “dispersive” electrode transversally on the proximal part of the thigh (in order to close the circuit).
