“…All ICC values were over 0.81, which has been described as an 'almost perfect' association between measurements (Landis and Koch 1977). Reliability of spinal posture measurement is critical to ensure that the presence or absence of an association between spinal posture and NSCLBP can be accurately estimated (Dartt et al 2009). A high degree of measurement error could result in subtle alterations in posture going unnoticed or, indeed, non-existent postural differences could be assumed on the basis of poor reliability.…”

“…The BodyGuard TM may allow investigation of whether factors such as postural variability or prolonged exposure to near end-range postures are predictors of LBP, as detailed examination of these relationships in the past has been constrained by technological limitations. Currently, digital photography and video analysis are commonly used in ergonomic research as they are the least invasive (Spielholz et al 2001, Dartt et al 2009, Straker et al 2009). In future trials, the device may offer more specific assessment of postural exposure while still allowing maximal work productivity.…”

The BodyGuard TM is a spinal position monitoring device that can monitor posture in real time, both inside and outside the laboratory. The reliability of this wireless device was examined in 18 healthy participants during usual sitting and forward bending, two tasks that are commonly provocative in NSCLBP. Reliability was determined using intraclass correlation coefficients (ICC), the standard error of measurement (SEM), the mean difference and the minimal detectable change (MDC90). Betweenday ICC values ranged from 0.84 to 0.87, with small SEM (5%), mean difference (59%) and MDC90 (514%) values. Inter-rater ICC values ranged from 0.91 to 0.94, with small SEM (4%), mean difference (6%) and MDC90 (9%) values. Between-day and inter-rater reliability are essential requirements for clinical utility and were excellent in this study. Further studies into the validity of this device and its application in clinical trials in occupational settings are required. Statement of Relevance:A novel device that can analyse spinal posture exposure in occupational settings in a minimally invasive manner has been developed. This study established that the device has excellent between-day and inter-rater reliability in healthy pain-free subjects. Further studies in people with low back pain are planned.

“…The selection of these criteria was based on similar studies of rater reliability (Dartt et al, 2009; Ebersole and Armstrong, 2002; Stevens et al, 2004) as well as other reliability statistics, such as the kappa coefficient and the intra-class correlation (Fleiss, 1986; Streiner and Norman, 2008). To evaluate if inter-rater reliability differed depending on whether the tasks rated were cyclic or non-cyclic, a two-sample Student's t -test (α = 0.05) using Satterthwaite's method for unequal variance compared the weighted mean z -scores from both task categories (Ott and Longnecker, 2010).…”

This study evaluated the inter-rater reliability of the American Conference of Governmental Industrial Hygienists (ACGIH®) hand activity level (HAL), an observational ergonomic assessment method used to estimate physical exposure to repetitive exertions during task performance. Video recordings of 858 cyclic and non-cyclic appliance manufacturing tasks were assessed by sixteen pairs of raters using the HAL visual-analog scale. A weighted Pearson Product Moment-Correlation Coefficient was used to evaluate the agreement between the HAL scores recorded by each rater pair, and the mean weighted correlation coefficients for cyclic and non-cyclic tasks were calculated. Results indicated that the HAL is a reliable exposure assessment method for cyclic (r̄-barw = 0.69) and non-cyclic work tasks (r̄-barw = 0.68). When the two reliability scores were compared using a two-sample Student's t-test, no significant difference in reliability (p = 0.63) between these work task categories was found. This study demonstrated that the HAL may be a useful measure of exposure to repetitive exertions during cyclic and non-cyclic tasks. Relevance to industry Exposure to hazardous levels of repetitive action during non-cyclic task completion has traditionally been difficult to assess using simple observational techniques. The present study suggests that ergonomists could use the HAL to reliably and easily evaluate exposures associated with some non-cyclic work tasks.

“…Besides that, another researcher also found that it is was difficult for an observer to assess whether the wrist angle was 15° or 20° from its neutral position during task performance [20]. Other than that, assessing the wrist posture for typing and clicking activities was more difficult to assess compared to other joints because it is dynamic posture (repetitive movement occur) [18]. The sentence for the item was also not clear so the keywords need to be bold.…”

“…Besides that, the observers found it difficult to observe and define the range of angular values during the assessment of items related to neck posture. In fact, other studies revealed that it is difficult for observers to determine the worker's posture angle based on observation only [8,15] A study by Dartt et al, [18] found that the assessment of wrist posture to be more difficult to assess compared to other joints because of its dynamic posture. In the OFFERA tool, the participants confirmed that it was easy to understand the scoring system (mean 4.59 ± 0.622), score for each items (mean 4.50 ± 0.792), the final score (mean 4.68 ± 0.639), and the action level (mean 4.52 ± 0.549) are useful.…”

Abstract. The OFFERA method was designed to assess the exposure of the office workstation risk factors associated with WMSDs. This method involved six domains which include chair, desk, input device, monitor, accessories, and the environment. The purpose of this study was to assess the usability of the OFFERA method for assessing exposure risks of computer work related to WMSDs. The participants were trained to conduct the OFFERA method. Trial assessments on three different office jobs were conducted. The usability of the OFFERA method was identified based on the feedback questionnaire survey obtained from 44 practitioners (undergraduate students) after the training. From the usability test, the OFFERA method was found be easy to use (mean 4.48 ± 0.698) and quick to use (mean 4.48 ± 0.821). However, the observers found that the font used was too small hence it was difficult to read the instruction (mean 3.93 ± 1.096). The pictures or illustrations in the OFFERA tool were also recorded as unclear based on the relatively low score for 18 items (mean 3.73± 1.128). Besides that, all participants agreed that OFFERA method is user-friendly, cost effective and applicable to a wide range of office-related activities.
