“…The three investigated performance tests have been reported to display good discriminative ability and high reliability [4,20,28,32,34,36,43]. This is in accordance with our results: the control group presented significantly higher outcome values in all performance tests, indicating good discriminative ability of these tests.…”

Considering the enormous costs of intensive multidisciplinary treatment, predictive tests for therapy outcome are needed to evaluate patients' performance potential and increase cost effectiveness. Somatic parameters are commonly used to evaluate health status and serve as an additional means of forecasting the prognosis, yet little is known of their validity. In this study, we investigated the prognostic value of somatic parameters regarding the outcome of multidisciplinary treatment in patients with subacute low back pain. The study was designed as a prospective cohort study of 162 patients. Somatic parameters were assessed with three physical performance tests (Villiger test, Oesch test, Biering-Sørensen test) before treatment (T0), after 3 weeks' inpatient therapy (T1) and at 6-month follow-up (T2). Psychometric characteristics of subjective pain perception (VAS), a pain disability index (PDI) and a physical capability index (FFbH-R) were recorded. Correlation coefficients between the physical performance test scores and psychometric characteristics were calculated. To predict therapy outcome, discriminant analyses were performed. A control group (n = 30) was evaluated at similar time points without receiving any therapy. Our results demonstrate good discrimination between patients and controls by means of the investigated performance tests and exhibit a significant negative correlation with the psychometric data. Lower outcome values at study entry correlated with higher pain intensity and disability after multidisciplinary treatment. However, the statistical magnitude of correlation was relatively low and further discriminant analysis did not reveal any predictive value. Consequently the physical performance tests do not have a prognostic value regarding therapy outcome.

“…Bono (2004) discussed the importance of both lower back dynamic power in movements such as the golf or baseball swing, a gymnast's landing, a power-lifter's squat and a boxer's punch, as well as static strength in examples such as an infielder's stance, a cyclers tuck or a ballerina's arabesque. Bono (2004) stated that "low back pain is a symptom not a diagnosis", which is fitting with studies that have shown a relationship between low back pain and weak lumbar musculature (Luoto, Heliövaara, Hurri, & Alaranta, 1995;Mayer, Graves, Robertson, Pierra, Verna & Ploutz-Snyder, 1999;Risch et al, 1993;Suni, Oja, Miilunpalo, Pasanen, Vuori & Bos, 1998). Other research has shown that the muscles of the lumbar region can be strengthened using specific isolated machine-based training, improving function and reducing low back pain symptoms and disability Choi, Pai Raiturker, Kyung-Joon, Dai Jin, Yu-Sik & Sang-Ho, 2005;Graves et al, 1990Graves et al, , 1994Pollock, Leggett, Graves, Jones, Fulton & Cirulli, 1989;Risch et al, 1993).…”

Objective: To consider the efficacy of 10 weeks of Romanian deadlift (DL) training in increasing lumbar extension strength compared to isolated lumbar extension (LUMX) training. Design: Comparison of pre-and post-test data for Romanian deadlift 1RM, and lumbar extension torque between and within groups. Participants: Male trained subjects (n ¼ 36; ðx AE SDÞ 24.9 AE 6.5 years; 178.5 AE 5.2 cm; 81.6 AE 10.0 kg). Main outcome measures: Pre-and post-testing included a Romanian deadlift 1RM and isometric strength tests every 12 through full range of motion on the MedX lumbar extension machine (MedX, Ocala, FL). Results: Repeated measures analysis of variance (ANOVA) with Bonferroni adjustments revealed that 1RM Romanian deadlift significantly increased from pre-to post-test in the DL group (p < 0.008; 143.3 AE 23.4 kg to 166.3 AE 21.9 kg) and the LUMX group (p < 0.008; 135.8 AE 23.1 kg to 146.0 AE 25.5 kg). In contrast, tested functional torque (TFT) significantly increased at 6 out of 7 joint angles (p < 0.008) for the LUMX group only. The control group showed no significant differences pre-to post-test. Conclusions: These data suggest that the Romanian deadlift does not enhance lumbar extension torque. However, performing specific isolated lumbar extension training appears to improve both lumbar extension torque and Romanian deadlift 1RM.

“…This variable has demonstrated to be related with the occurrence of low-back pain (14,15) , once the IRT of volunteers with low-back pain has demonstrated to be significantly lower when compared with healthy volunteers (2,16,17) . Other variable related with the etiology of the low-back disorders is the muscular strength.…”

“…In the last years, considerable interest has arisen in the practice of physical exercises as therapeutic resource for low-back pain prevention and treatment, what may be explained by the consistent reports that weakness and low isometric resistance of the lumbar spinae erector muscles are associated with the etiology of the low-back pain (1,2) .…”

The low-back pain has demonstrated to be a common finding among athletes and particularly the overload in the lumbar column resulting from a strength or isometric resistance involvement of muscles of this segment as result of the muscular fatigue has been considered as important etiological factor for its development. In this context, tests used for the training evaluation of the lumbar spinae erector muscles are emphasized. In the present study, the analysis of the strength and isometric resistance parameters was used with the objective of evaluating responses of these muscles during maximal and sub-maximal voluntary isometric contractions (MVIC) in two situations: with fatigue and without fatigue induced by isometric exercise performed until exhaustion. Nine male healthy volunteers performed MVIC before and after vertebral column extension exercises supporting 5%, 10%, 15% and 20% of the MVIC. In each one of these situations, the electromyographic signal (EMG) of the iliocostalis and multifidus muscles as well as the strength level generated in the MVIC were recorded. Muscular fatigue was identified through the MVIC values decrease verification and median frequency (MF) of the EMG signals obtained after isometric exercise. The results demonstrated that while the strength was able to evidence muscular fatigue, the MF demonstrated in a statistically significant way the iliocostalis and multifidus muscles fatigue, and the multifidus muscles presented a higher muscular fatigue level. Interestingly, loads between 5% and 20% of the MVIC induced the same level of muscular fatigue. Thus, although the strength generated during vertebral column extension after isometric exercise-induced exhaustion remains unchanged, probably due to the action of accessory muscles, the overload on the vertebral column is developed as result of the vertebral column stability involvement resulting from the muscular fatigue identified after isometric exercise.
