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 ▲]

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 ▲]

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.

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 ▲]
