Context:Back-muscle fatigue and lumbar curvature are related to low back pain, but the relation between them is unknown.Objective:To clarify whether lumbar curvature changes with back-muscle fatigue.Design:Prospective pseudorandomized.Setting:Laboratory.Participants:13 healthy men without low back pain.Intervention:To induce back-muscle fatigue, subjects performed a repetitive prone back-extension exercise from 45° to 0° until exhaustion and then rested 10 min. They performed this exercise 3 times.Main Outcome Measures:Before the trial and after each exercise, lumbar curvature was measured with a Spinal Mouse.Results:After back-muscle fatigue, lumbar curvature decreased significantly (P < .01). This decrease occurred at L4–S1, which was defined as the lower spine. On the contrary, curvature of the upper lumbar spine, at Th12–L4, did not decrease.Conclusion:Lumbar curvature, especially the lower portion, decreased with back-muscle fatigue induced by prone back-extension exercise.

AbstractThe impact of aging on the back muscles is not well understood, yet may hold clues to both normal aging and chronic low back pain (cLBP). This study sought to investigate whether the median frequency (MF) surface electromyographic (SEMG) back muscle fatigue method—a proxy for glycolytic muscle metabolism—would be able to detect age- and sex-specific differences in neuromuscular and muscle metabolic functions in individuals with cLBP in a reliable way, and whether it would be as sensitive as when used on healthy individuals. With participants seated on a dynamometer (20° trunk anteflexion), paraspinal SEMG activity was recorded bilaterally from the multifidus (L5), longissimus (L2), and iliolumbalis (L1) muscles during isometric, sustained back extensions loaded at 80% of maximum from 117 younger (58 females) and 112 older (56 female) cLBP individuals. Tests were repeated after 1–2 days and 6 weeks. Median frequency, the SEMG variable indicating neuromuscular fatigue, was analyzed. Maximum back extensor strength was comparable between younger and older participants. Significantly less MF-SEMG back muscle fatigue was observed in older as compared to younger, and in older female as compared to older male cLBP individuals. Relative reliability was excellent, but absolute reliability appeared large for this SEMG-fatigue measure. Findings suggest that cLBP likely does not mask the age-specific diagnostic potential of the MF-SEMG back extensor fatigue method. Thus, this method possesses a great potential to be further developed into a valuable biomarker capable of detecting back muscle function at risk of sarcopenia at very early stages.

Prolonged Sitting

Low-back pain is one of the consequences of sitting. Muscular fatigue leads to shifting from a straight posture into a slumped one. We believe that corrective supports to the pelvis and lumbar spine must be complemented with restraining shoulder straps to bypass muscle fatigue. This ergonomic design “formula” could potentially improve prolonged passive sitting conditions, such as on long-haul flights, in which most passengers sit in cramped surroundings. Our study’s results confirm this hypothesis. Further studies are required concerning cardiac and circulatory responses to the use of this device.

Kinesio Taping

OBJECTIVE: To evaluate the effect of different taping techniques on back muscle fatigue in people with low back pain. METHODS: Sixty women with chronic non-specific low back pain were randomly assigned to four groups of 15 participants each: control (CG), Kinesio Taping (KT) with tension (KTT), KT no tension (KTNT) and Micropore® (MP), which were applied over the erector spinae muscles. The median frequency (MF) fatigue slopes of the longissimus muscle and sustained contraction time during a trunk fatigue test (Ito test), and pain using the numerical pain rating scale (NPRS) were collected at three time points: pre-treatment, three and ten days after intervention at a university laboratory. RESULTS: Significant differences were seen in the MF slopes between groups (p= 0.01, η2= 0.20), with the KTT showing a mean difference (MD = 0.31, p= 0.04) and KTNT (MD = 0.28, p= 0.04) compared with CG. Significant reductions in NPRS were seen between time points (p< 0.001, η2= 0.28), with a reduction between pre and 3 days (MD = 1.87, p< 0.001), and pre and 10 days (MD = 1.38, p< 0.001), with KTT and KTNT both showing clinically important changes. CONCLUSION: KT, with or without tension, has a tendency to reduce back muscle fatigue and reduce pain in individuals with chronic non-specific low back pain.
