The association between isoinertial trunk muscle performance and low back pain in male adolescents

Abstract

The literature reports inconsistent findings regarding the association between low back pain (LBP) and trunk muscle function, in both adults and children. The strength of the relationship appears to be influenced by how LBP is qualified and the means by which muscle function is measured. The aim of this study was to examine the association between isoinertial trunk muscle performance and consequential (non-trivial) low back pain (LBP) in male adolescents. Healthy male adolescents underwent anthropometric measurements, clinical evaluation, and tests of trunk range of motion (ROM), maximum isometric strength (STRENGTH) and peak movement velocity (VEL), using an isoinertial device. They provided information about their regular sporting activities, history and family history of LBP. Predictors of ''relevant/consequential LBP'' were examined using multivariable logistic regression. LBP status was reassessed after 2 years and the change from baseline was categorised. At baseline, 33/95 (35%) subjects reported having experienced consequential LBP. BMI, a family history of LBP, and regularly playing sport were each significantly associated with a history of consequential LBP (p \ 0.05). 85/95 (89%) boys participated in the follow-up: 51 (60%) reported no LBP at either baseline or follow-up (never LBP); 5 (6%) no LBP at baseline, but LBP at follow-up (new LBP); 19 (22%) LBP at baseline, but none at follow-up; and 10 (12%) LBP at both time-points (recurrent/persistent LBP). The only distinguishing features of group membership in these small groups were: fewer sport-active in the ''never LBP'' group); worse trunk mobility, in the ''persistent LBP'' group, lower baseline sagittal ROM in the ''never LBP'' and ''new LBP'' (p \ 0.05). Regular involvement in sport was a consistent predictor of LBP. Isoinertial trunk performance was not associated with LBP in adolescents.

Low back pain in adolescent and associated factors: A cross sectional study with schoolchildren

“…Because most of the studies20 , 32 , 33 are generally focused on excess body weight, it is necessary to evaluate the influence of the non-respondents, but it was not possible to carry out this procedure, in the present study.…”

Back and neck pain prevalence and their association with physical inactivity domains in adolescents

“…However, the authors did not stratify the sample into active and inactive individuals, noting that the practice of sports activities outside the school environment was not associated with the occurrence of low back pain. Nonetheless, Balagué et al [24] reported that adolescents, who were involved in sports programs, had higher chances of the occurrence of low back pain. Sitthipornvorakul et al [25] in a systematic review found no association between physical activity and neck pain, and there is still conflict in the literature when associating physical activity and low back pain.…”

Ocorrência de dor lombar e fatores associados em crianças e adolescentes de uma escola privada do sul do Brasil

“…Diepenmaat et al 33 identificaram que sintomas depressivos e estresse estavam associados à dor no pescoço e nos braços e à dor lombar em adolescentes de 12 a 16 anos. Investigações que utilizaram o mesmo questionário aplicado no presente estudo, também encontraram os fatores psicossociais como associados à dor lombar: maior pontuação total no questionário associou--se à dor nas costas e no pescoço 39 ; a categoria anormal dos sintomas emocionais, em relação à normal, apresentou razão de chance de 1,65 40 ; problemas de conduta e sintomas emocionais se associaram à dor lombar em escolares de 11 a 14 anos 20 ; a variável "problemas de relacionamento com colegas" foi uma das preditoras de dor lombar persistente em estudo de acompanhamento de quatro anos 9 e, também em estudo longitudinal, jovens com problemas de conduta e hiperatividade apresentaram risco aumentado para dor lombar um ano após a avaliação inicial 41 . A prática de exercício para além das aulas de Educação Física não se associou à ocorrência de dor lombar.…”
