“…Non-PDs performed a higher frequency of large weight transfers during the first 15 min of standing compared to PDs, but a similar frequency of smaller transfers. This is different than previous results, which found that the frequency of body weight shifts increased over time; however, large and small body weight transfers were not separated (Gallagher et al, 2011). We hypothesized that a difference between the pain groups would exist because of the higher gluteus medius co-contraction in PDs.…”

“…This co-activation occurs prior to pain development and has been proposed to compensate for an inability to control trunk and abdominal muscles for effective postural control during prolonged standing (Nelson-Wong & Callaghan, 2010b). We originally hypothesized that co-activation may prevent PDs from transferring their weight between their legs; however, weight transfers from one leg to another become more frequent the longer a person stands, independent of pain group (Gallagher, Nelson-Wong, & Callaghan, 2011). Non-PD also utilize a greater range of their lumbar spine motion during both standing and sitting when working at a computer compared to PDs, and the large shift from standing to sitting reduced the self-reported LBP reports of PDs (Gallagher et al, 2014).…”

“…In standing, loading and unloading of the lower limbs is a common movement pattern that should allow for relaxation of the muscles in the unloaded limb (Carlsöö, 1961). We previously assessed body weight transfers from one leg to another during prolonged standing (Gallagher et al, 2011); however, we did not separate out different magnitudes of movement between PDs and non-PDs. In order to quantify the types of movement occurring in standing, Duarte and Zatsiorsky (1999) defined three types of center of pressure patterns evident in unconstrained standing (1) fast and large displacement of center of pressure that returns to approximately the same location (fidget), (2) a fast displacement of the center of pressure from one location to another (shift), and (3) a slow continuous displacement (drift).…”

“…What is clear from all available reviews is that further evidence—from high-quality, longitudinal epidemiological studies using objective measures of occupational standing and from laboratory studies—is needed to provide more convincing evidence of an association. Such studies can also help to determine the dose-response relationship, understand the mechanisms (eg, muscle fatigue75 and postural changes76 77) and provide evidence for thresholds of excessive standing.…”

Associations of occupational standing with musculoskeletal symptoms: a systematic review with meta-analysis

et al. 2016

Objective: Given the high exposure to occupational standing in specific occupations, and recent initiatives to encourage intermittent standing among white-collar workers, a better understanding of the potential health consequences of occupational standing is required.We aimed to review and quantify the epidemiological evidence on associations of occupational standing with musculoskeletal symptoms.Design: A systematic review was performed. Data from included articles were extracted and described, and meta-analyses conducted when data were sufficiently homogenous. Conclusions: The evidence suggests that 'excessive' occupational standing is associated with the occurrence of low-back and (inconclusively) lower extremity symptoms, but there may not be such an association with upper extremity symptoms. Only limited evidence from high quality, longitudinal studies using objectively measured standing was found.  The association of occupational standing with musculoskeletal symptoms is yet unclear, with no current systematic review quantifying this association. WHAT ARE THE NEW FINDINGS: We systematically reviewed literature and identified substantial evidence (50 articles from n=88,158 participants) describing associations of occupational standing with low-back, lower extremity and upper extremity symptoms. We found evidence (including pooled data from a meta-analysis) for associations between occupational standing and the occurrence of low-back and (inconclusively) lower extremity symptoms, however not for upper extremity symptoms. We found only limited evidence from high quality, longitudinal studies using objectively measured standing was found. Such information is needed to provide more definitive evidence to inform good work design for both blue-and white-collar workers.4

“…In previous studies investigators have used an induced pain paradigm to examine factors that may contribute to LBP symptoms during prolonged standing (Gregory and Callaghan, 2008; Gregory et al, 2008; Gallagher et al, 2011; Nelson-Wong et al, 2008; Nelson-Wong et al, 2009; Nelson-Wong and Callaghan, 2010c; Nelson-Wong et al, 2010; Nelson-Wong and Callaghan, 2010b; Nelson-Wong and Callaghan, 2010a; Nelson-Wong et al, 2012; Nelson-Wong and Callaghan, 2014; Marshall et al, 2011). The paradigm requires back-healthy people to stand for 2 hours while performing simulated, light work tasks.…”

Background An induced-pain paradigm has been used in back-healthy people to understand risk factors for developing low back pain during prolonged standing. Objectives The purposes of this study were to (1) compare baseline lumbar lordosis in back-healthy participants who do (Pain Developers) and do not (Non-Pain Developers) develop low back pain during 2 hours of standing, and (2) examine the relationship between lumbar lordosis and low back pain intensity. Design Cross-Sectional Method First, participants stood while positions of markers placed on the lumbar vertebrae were recorded using a motion capture system. Following collection of marker positions, participants stood for 2 hours while performing light work tasks. At baseline and every 15 minutes during standing, participants rated their low back pain intensity on a visual analog scale. Lumbar lordosis was calculated using marker positions collected prior to the 2 hour standing period. Lumbar lordosis was compared between pain developers and non-pain developers. In pain developers, the relationship between lumbar lordosis and maximum pain was examined. Results/findings There were 24 (42%) pain developers and 33 (58%) non-pain developers. Lumbar lordosis was significantly larger in pain developers compared to non pain developers (Mean difference=4.4°; 95% Confidence Interval=0.9° to 7.8°, Cohen’s d=0.7). The correlation coefficient between lumbar lordosis and maximum pain was 0.46 (P=0.02). Conclusion The results suggest that standing in more lumbar lordosis may be a risk factor for low back pain development during prolonged periods of standing. Identifying risk factors for low back pain development can inform preventative and early intervention strategies.
