Ergonomic Analysis to Support Surgery-Averse Individuals that Live with Chronic Pain
Published in Marcelo M. Soares, Franscisco Rebelo, Advances in Usability Evaulation, 2013
Gathering and analyzing evidence for functional assessment of elderly and OA populations has been subject of many review articles (e.g. Collier, 1988; Liang and Jette, 1981). Similarly, OA outcomes measures range from joint-specific, self-administered questionnaires, such as the “Knee Injury and Osteoarthritis Outcome Score” (KOOS) (Roos, et al., 1998), to the WOMAC instrument which has been studied in relationship with drug therapy and OA pain assessment (Bellamy, et al., 1988; Bellamy, 1989). These outcomes measurement tools allow for reliable metrics of clinical performance and reliable ways to assess functional capacities for this population, and can be used with non-disease specific outcomes measurement tools such as the Barthel ADL Index (Mahoney and Barthel, 1965) to expand the evidence base for ergonomic interventions.

For subject self-report, a Likert scale satisfaction system was used, alongside a visual analog scale (VAS) for pain levels and the Western Ontario and McMaster Universities Arthritis Index (WOMAC) for function. The VAS, with a scale from 0 to 10, was used purely for pain severity. The WOMAC score was ascertained by a self-administered questionnaire consisting of 24 items and subdivided into three categories: pain (5 items), stiffness (2 items), and difficulty performing daily activities (17 items). The Likert scale was a semi-quantitative self-rating liner measurement system, with a scale from 0 (much dissatisfied) to 5 (much satisfied), being used to assess levels of user satisfaction.

The sensory and instrumental assessment methods applied in RCT were presented in Figure 9. In the wear trial, knee pain, knee stiffness and physical function was assessed as the primary outcomes by applying Western Ontario and McMaster Universities Osteoarthritis (WOMAC) Index. The WOMAC has been widely adopted as an outcome measurement in many studies of acu-therapeutic treatments for KOA [26,27]. This index consists of three parts including pain, stiffness, and physical function. It is available in over 100 alternate language forms with the surveyed items quantified as 5-point Likert, 100mm Visual Analogue or 11-box Numerical Rating Scale formats that have been validated by previous research studies (Baron et al., 2007; Soininen et al., 2008). Considering the language capabilities of the studied subjects, a Chinese WOMAC version validated by Xie et al. (2008) was employed in this study. This validated questionnaire has 24 items and each of them was graded on a 5-point Likert-scale with the score ranging from 0 to 4 to match the scale of difficulty from ‘none’ to ‘extremely’ (0=None, 1=Slight, 2=Moderate, 3=Very, 4=Extremely). In general, the WOMAC index involved the two question items for knee stiffness parameter, five for knee pain, and seventeen for physical function ability during daily activities, including: stair use, rising from sitting, standing, bending, walking, getting in/out of a car, shopping, putting on/taking off socks, rising from bed, lying in bed, getting in/out of bath, sitting, getting on/off toilet, and heavy/light household duties. The higher the total scores of the tested index, the worse the KOA condition.

The WOMAC (Western Ontario and McMaster Universities) is a multidimensional measure of pain, stiffness, and physical functional disability symptoms (Bellamy, Buchanan, Goldsmith, Campbell, & Stitt, 1988). The WOMAC questionnaire is rated on an ordinal scale of 0–4, with lower scores indicating lower levels of symptoms or physical disability. Each subscale is summated to a maximum score of 20, 8, and 68, respectively. The global index score was calculated by summating the scores for the three subscales. Participants completed the Spanish version of the WOMAC questionnaire (Escobar, Quintana, Bilbao, Azkárate, & Güenaga, 2002).
