Background. Reaction time is a reliable indicator of the velocity and efficiency of neuromuscular control and may be associated with fear-avoidance beliefs. However, the effect of exercise-induced muscle fatigue on reaction time in chronic low back pain (cLBP) and its relationship with fear-avoidance beliefs remains poorly understood. Objectives. This study aimed to reveal the relationship between fear-avoidance beliefs and reaction time changes before and after exercise-induced muscle fatigue in cLBP. Methods. Twenty-five patients with cLBP were tested by the Biering–Sorensen test (BST) to induce exhaustive muscle fatigue. Total reaction time (TRT), premotor time (PMT), and electromechanical delay (EMD) of dominated deltoid muscle were recorded by surface electromyography during the arm-raising task with visual cues before and after muscle fatigue. The mean difference (MD) of TRT (MDTRT), PMT (MDPMT), and EMD (MDEMD) was calculated from the changes before and after muscle fatigue. Fear-avoidance beliefs questionnaire (FABQ) was applied to evaluate fear-avoidance beliefs before muscle fatigue. In addition, the duration time of BST was recorded for each subject. Results. TRT and PMT of dominated deltoid muscle were prolonged after exercise-induced muscle fatigue (Z = 3.511, p<0.001; t = 3.431, p=0.001), while there was no statistical difference in EMD (Z = 1.029, p=0.304). Correlation analysis showed that both the MDTRT and MDPMT were positively correlated with FABQ (r = 0.418, p=0.042; r = 0.422, p=0.040). Conclusions. These findings suggested that we should pay attention to both muscle fatigue-induced reaction time delay in cLBP management and the possible psychological mechanism involved in it. Furthermore, this study implied that FABQ-based psychotherapy might serve as a potential approach for cLBP treatment by improving reaction time delay. This trial is registered with ChiCTR2300074348.

“…having to modify at least one foot position to avoid falling. This interesting parameter has been encountered to evaluate the effect of balance training using virtual reality in elderly [32], the influence of knee or ankle immobilization [54] or the ability of cerebral palsy children to reject the perturbation induced by arm raising [64]. A multi-segments model is employed to explore the influence of low-back pain on monopodal posture and to estimate stability through two indices: kinetic, based on ground force; and kinematic, based on segment orientation [65].…”

“…Although our primary research interests focused on the children's arm movements exhibited while hammering, we recognize that limb activity occurs within the body's postural context. Postural adjustments contribute to preparation as well as execution of arm movements (e.g., Ledebt & Savelsbergh, ) and postural control is necessary for accurate performance of voluntary movements (van der Fits & Hadders‐Algra, ) but postural strategies are still developing during early childhood (Viholainen, Ahhonen, Cantell, Tolvanen, & Lyytinen, ). For seated reaching (a more stable task environment than ours), postural adjustments are not necessarily displayed by children up to 18 months of age (van der Fits & Hadders‐Algra, ).…”

Hammering with a hand tool appears early in life. Skillful hammering involves accommodating movements to properties of the hammer, orienting the hammer's head to the item to be struck, and maintaining stable posture during forceful action with the arm(s). We aimed to characterize development of these abilities in young children (12, 18, and 24 months old). Children struck at a peg with a hammer held in the hand or a hammer attached to a handle. Children struck more frequently with a hard hammer surface than a soft one, and more frequently (although less accurately) with handled hammers than with non-handled hammers. Developmental differences were evident in accuracy, number of strikes, and kinematic parameters, especially with the handled object. Children's ability to use objects for forceful and accurate percussion changed measurably over the second year, in tandem with improving postural stability and greater motion of the elbow.
