“…Our study identified that PD had poorer trunk (abdominal and lumbar) muscle strength/endurance and greater self-rated difficulty performing an ASLR than NPD. In contrast to our findings, the few studies that have assessed trunk muscle function in relation to standing-induced LBP did not find that deficits of endurance/strength [ 19 , 22 ] or ASLR performance [ 15 , 19 ] discriminated between PD and NPD. One key difference between our study and this previous work is the population studied.…”

“…Researchers have suggested an association between (i) reduced hip abductor muscle endurance [ 13 , 14 ]; (ii) reduced endurance or strength of the trunk muscles [ 13 , 15 , 16 , 17 , 18 ]; and (iii) movement control dysfunction [ 15 , 17 , 19 ] and the development of LBP during standing. However, the evidence is inconsistent and studies have used university students and community volunteers, rather than office workers [ 13 , 15 , 19 , 20 , 21 , 22 ].…”

This study examines demographic, physical and psychosocial factors associated with an increase in low back pain (LBP) during a one-hour standing task. A cross-sectional survey with 40 office workers was conducted. The primary outcome was pain severity during a one-hour standing task recorded every 15 min using a 100 mm Visual Analogue Scale (VAS). Participants were defined as pain developers (PD), if they reported a change in pain of ≥10 mm from baseline, or non-pain developers (NPD). Physical outcomes included participant-rated and examiner-rated trunk and hip motor control and endurance. Self-report history of LBP, physical activity, psychosocial job characteristics, general health and pain catastrophising were collected. Fourteen participants were PD. Hip abduction, abdominal and spinal muscle endurance was lower for PD (p ≤ 0.05). PD had greater self-reported difficulty performing active hip abduction and active straight leg raise tests (p ≤ 0.04). Those reporting a lifetime, 12 month or 7-day history of LBP (p < 0.05) and lower self-reported physical function (p = 0.01) were more likely to develop LBP during the standing task. In conclusion, a history of LBP, reduced trunk and hip muscle endurance and deficits in lumbopelvic/hip motor control may be important to consider in office workers experiencing standing-induced LBP.

“…In addition, the LLA of the patients showed much higher standard deviations than that of the healthy subjects, suggesting a greater variations in the load distributions between the two legs due to LDH. Clinical observations suggest that people with lower back pain performed more body weight shifts to reduce the discomfort 28,29 . It is noteworthy that when standing on a sloped surface, the patients with LDH, rather than the healthy subjects, showed higher but more variant LLA.…”

the changes of balance control mechanism caused by lumbar disc herniation (LDH) has not been well understood. This study aimed to investigate the effects of LDH on the balance control during standing on sloped surfaces. Ten patients with LDH and 10 gender-and age-matched healthy subjects were instructed to stand quietly on a sloped surface at −5°, 0° or +5°, respectively. The trajectories of the center of pressure (COP) of each individual limb and the full-body were recorded. Cross recurrence quantification analysis (CRQA) was applied to assess the coordination of COP components at the anterior-posterior and medial-lateral directions. The patients with LDH presented magnified inter-limb load asymmetry and had more deterministic components in the COP coordination of the less-affected limb and the full-body than the healthy subjects. The LDH led to decreased dynamical degree of freedom and less flexibility in bidirectional controlling the center of mass simultaneously. The effects of sensorimotor deficits due to LDH could be more obviously exhibited as standing on a declined rather than an inclined surface. This study shed light on the effects of LDH on standing balance control and may facilitate to develop novel strategies for evaluation of LDH.Experimental set-up. A force platform (FDM-S, Zebris Medical GmbH, Isny, Germany) covered with 64*40 pressure sensors was used to measure the foot plantar pressure distributions at a sampling frequency of 60 Hz. The COP time series were processed in the MATLAB R2017b (The Mathworks, Natick, MA, USA). Parameters of CRQA were implemented with the cross recurrence plot toolbox 5.16 23 . test procedures. The schematic diagram of the experiment set-up is depicted in Fig. 1. Subjects were required to stand barefoot quietly on the center of the force platform for 30 s, with their feet side by side, their hands naturally on both sides of body and their eyes gaged forward. Three angles of the force platform surface, including −5°, 0° and +5° with respect to the horizontal plane, were tested with a random sequence. For each surface angle, only one trial was performed by each subject. A 5-min rest was given between trials.

This study shed light on the effects of LDH on standing balance control and may facilitate to develop novel strategies for evaluation of LDH.

“…27 Therefore, postural control is different in the healthy and low back pain populations. 28,29,30,27 Chronic LBP subjects have a greater postural sway in anterior-posterior and medial-lateral directions during quiet standing than healthy people. 27,29 During prolonged standing, however, when the subjects were allowed to make voluntary movements, patients with chronic LBP swayed less than healthy subjects in both the anterior-posterior and medial-lateral directions.…”
