“…In general, these findings concur with those of other systematic reviews and individual studies [43,[66][67][68][69]. As highlighted before [16], if specific types of exercise therapy are to be advocated-especially those that aim to target specific functional deficits-it is important to be able to establish that improvements in the clinical complaint after therapy are in some way associated with the specific changes in function elicited.…”

“…Based on the findings of our review and on similar information from other systematic reviews and studies [43,[66][67][68][69], we suggest that changes in physical function are largely unable to explain changes in the clinical condition in cLBP patients, and that the important ''side effects'' of exercise therapy (including, amongst other things, changes in psychological variables such as fear-avoidance beliefs, catastrophising and self-efficacy regarding paincontrol) should be more specifically emphasised and investigated in future rehabilitation programs.…”

Introduction The effect size for exercise therapy in the treatment of chronic non-specific low back pain (cLBP) is only modest. This review aims to analyse the specificity of the effect by examining the relationship between the changes in clinical outcome (pain, disability) and the changes in the targeted aspects of physical function (muscle strength, mobility, muscular endurance) after exercise therapy. Methods We searched for exercise therapy trials for cLBP published up to 15 April 2010 in Medline, Embase, Cochrane Library, Cinahl, and PEDro. Two independent reviewers selected studies according to the inclusion criteria. Data extraction: one author extracted the data of the articles. Results Data synthesis: 16 studies with a total of 1,476 participants met the inclusion criteria. There was little evidence supporting a relationship between the changes in pain or physical function and the changes in performance for the following measures: mobility (no correlation in 9 studies, weak correlation in 1 study), trunk extension strength (7 and 2, respectively), trunk flexion strength (4 and 1, respectively) and back muscle endurance (7 and 0, respectively). Changes in disability showed no correlation with changes in mobility in three studies and a weak correlation in two; for strength, the numbers were four (no correlation) and two (weak correlation), respectively. ConclusionsThe findings do not support the notion that the treatment effects of exercise therapy in cLBP are directly attributable to changes in the musculoskeletal system. Future research aimed at increasing the effectiveness of exercise therapy in cLBP should explore the coincidental factors influencing symptom improvement.

“…Contrary to what one would expect due the neuromuscular imbalance of ES in LBP subjects (Renkawitz et al, 2006), left ES did not show a discriminative power comparatively with the trunk rotators and thigh muscles. Cole and Grimshaw, (2008b) found that the LHc LBP golfers present lower ES activity than the LHc NLBP.…”

Correia, P. (2015). Recurrence quantification analysis and support vector machines for golf handicap and low back pain EMG classification. Journal of Electromyography & Kinesiology, 25, AbstractThe quantification of non-linear characteristics of electromyography (EMG) must contain information allowing to discriminate neuromuscular strategies during dynamic skills. In golf, both handicap (Hc) and low back pain (LBP) are main factors associated with the occurrence of injuries. The aim of this study was to analyze the accuracy of support vector machines SVM on EMG-based classification to discriminate Hc (low and high handicap) and LBP prevalence (with and without LPB) in the main phases of golf swing. For this purpose recurrence quantification analysis (RQA) features of the trunk and the lower limb muscles were used to feed a SVM classifier. Recurrence rate (RR) and the ratio between determinism (DET) and RR showed a high discriminant weight. The Hc classifications accuracy for the swing, backswing (BS), and downswing (DS) were 94.4±2.7%, 97.1±2.3%, and 95.3±2.6%, respectively. For LBP, the accuracy was 96.9±3.8% in the swing, and 99.7%±0.4% in BS. External oblique (EO), biceps femoris (BF), semitendinosus (ST) and rectus femoris (RF) showed high accuracy depending on the laterality within the phase. RQA features and SVM showed a high capacity in discriminating muscles within swing phases by Hc and by LBP. Low back pain golfers showed less neuromuscular coordination strategies than asymptomatic.

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.…”

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.
