“…All participants were informed about equipment operation, measurement protocol procedure and performance of maximum force to familiarize them with the dynamometer. Subsequently, according to evaluator signal, the volunteer was instructed to perform a maximum contraction, seeking to exert force from lumbar muscles, and this procedure was performed twice, with one-minute interval between measurements, and obtained mean measures 16 ) .…”

[Purpose] To estimate the effect of Klapp method on idiopathic scoliosis in school students. [Subjects and Methods] A single-blind randomized clinical trial with 22 students randomly divided into intervention group (n=12) and inactive control group (n=10). Exercise protocol consisted of Klapp method, 20 sessions, three times a week for intervention group, and inactivity for control group. Dorsal muscle strength was measured by dynamometer; body asymmetries and gibbosity angles were measured by biophotogrammetry. Data were obtained by Generalized Estimated Equation, with 5% significance level. Clinical impact for dependent variables was estimated by “d” Cohen. [Results] There was no change in intragroup analysis and intergroup for all postural symmetry variables. However, it was detected intergroup difference in extensor muscle strength and intergroup difference with marginal significance of gibbosity angles. Regarding extensor muscle strength, intervention group produced average improvement of 7.0 kgf compared to control group. Gibbosity angles progressed less in intervention group, with 5.71° average delay compared to control group. [Conclusion] Klapp method was effective for gibbosity stabilization and it improves spine extensor muscle strength.

“…total. The participant was positioned standing on the equipment platform with full knee extension, trunk flexed at approximately 120º and the head following the extension of the trunk, with the gaze fixed ahead, hands holding the equipment bar positioned in the anterior part of the lumbar dynamometer (16) . At the end of the positioning, the participant was asked to perform the greatest possible trunk extension (17) .…”

“…During this movement, the arms remain extended, preventing the subject from performing any type of additional movement with the upper limbs (18) . This test was performed three times with submaximal force so that the patient understands how the test works, and twice with maximum force with a 1-minute interval between tests (16) . For data analysis, the highest value obtained was used.…”

Background: Low back pain (LBP) is characterized as pain or discomfort located in the region below the rib cage and above the upper gluteal line. Some factors, such as a low level of physical activity or a sedentary lifestyle and poor posture during work activities, contribute to the chronification of pain. Objective: To investigate whether physical activity influences functional capacity, pain intensity and trunk extensor strength in individuals with chronic LBP. Methods: The sample was composed of 30 adult individuals, aged between 18 and 30 years, of both genders. They were divided into two groups, sedentary (SG, n=17) and active people (AG, n=13). The IPAq was used to classify the participants between sedentary and active people. Afterwards, the Roland Morris Disability and the SF-36 quality of life questionnaires were applied. Pain intensity was obtained by the Numerical Pain Scale (NDS). After that, the Sitting and Reaching Test (SCT) and the evaluation of the strength of the trunk extensor muscles were performed. At the end of the evaluations, a lumbar overload protocol was performed. After five minutes, pain intensity, flexibility, and muscle strength were reassessed. For data interpretation, a significance level of p < 0.05 was adopted. Results: After the lumbar overload protocol, the GS showed an increase in the flexibility of the posterior chain in the SRT and there was a increase in pain for both groups. Conclusion: individuals with chronic LBP, with similar levels of Quality of Life, pain intensity and disability, regardless of being active or sedentary, do not differ in pain perception, flexibility and ability to generate trunk extension force after being submitted to a lumbar overload protocol. Furthermore, the lumbar overload protocol was efficient in generating increased pain in both groups.

Introduction:The low back pain is the most prevalent between the musculoskeletal disorders, and it is the most common reasons of absence from work. The flexibility, mobility, strength and endurance of the low back stability influence and the disharmony between these factors may result in low back pain. One of Maitland's technique, which alter these factors, is posteroanterior (PA) mobilization. Objective: To analyze the posterior chain's flexibility, low back's mobility, trunk extensor's endurance and low back extensors' muscle strength after performed one treatment session using the Maitland method on youth with low back pain. Method: For this research, sixteen women (22 ± 3.03 years) with chronic low back pain participated. All volunteers were evaluated according to their perception of pain, flexibility, mobility, muscular strength and muscular endurance. The treatment protocol was the application of PA mobilization on the five lumbar vertebrae, from caudal direction to cranial, of three series of one minute in each vertebra. The same procedures of the initial evaluation were performed after the immediate application of PA mobilization technique (revaluation 1) and 7 days after the protocol (revaluation 2). The data were analyzed by the Shapiro-Wilk's normality test; analysis of variance (ANOVA) repeated measures one-way with pos-hoc Bonferroni and Friedman's ANOVA with pos-hoc Wilcoxon, with the level of significance of 5% (p< 0,05). Results: After PA mobilization application, there were significant improvements in muscular strength (immediate post-treatment and past seven days) and muscular endurance (immediate post-treatment). There were no significant improvements in the other variables, such as, level of pain, and lumbar flexibility and mobility. Conclusion: The lumbar PA mobilization was effective for increasing muscular strength and endurance, with stabilization of the level of pain, flexibility and mobility.

Abstract: Normotensive and hypertensive workers showed no significant differences in the performance of static muscular strength tests; however, body mass and gender seem to affect the association between muscle strength and blood pressure.
