Conclusion: Numerous scar assessment tools exist to assist clini- cians in the evaluation of scars; however, there is a significant gap in the breadth of the psychometric evidence supporting these tools. Further studies should be conducted to facilitate the evaluation of scars for both clinical and scientific support of outcome measure- ment in hand surgery and rehabilitation. POSTER PRESENTATIONS 17 How Can Joint Protection Apply to Grocery Shopping?; An Evaluation to Determine the Optimal Handle Diameter of Shopping Carts. K. NOTTELMANN, F. WOODS, M. PITTSLEY, J. BEASLEY, B. ASHBY, K. ANDERSON Grand Valley State University, Grand Rapids, Michigan, United States Purpose: Joint protection is important for individuals with arthritis to avoid pain and facilitate performance in daily activities. Individuals with rheumatoid arthritis ranked mobility during shopping as an activity that was limited by the symptoms of arthritis. An individual’s ability to complete IADLs such as shopping is a significant predictor of his or her ability to live independently. The appropriate handle size has the potential to protect the joints during shopping, however, there is currently, no research on handle diameter preference while shopping or research on what handle diameter requires the least amount of pressure to protect the joints while shopping. To evaluate the pressure applied by the hand and handle preference reported by participants when using three different shopping cart handles (diameters of 26.0 mm, a common standard handle diameter; 33.0 mm; and 38.1 mm, based on review of the literature). A Novel Pliance-X hand sensor measured hand pressure on the handle and participant questionnaires revealed preference. Conclusion: The largest handle required the least amount of pressure, but the participants preferred the mid-sized handle. Results: The largest handle (38.1 mm) resulted in the least amount of pressure while the standard handle (26.0 mm) required the most amount of pressure. The participants rated the mid-sized handle (33.0 mm) most favorably. Methods: Thirty-seven subjects without hand conditions or his- tory of hand injuries were randomized into six groups for the three handle diameter trials. For each trial, the subjects maneuvered a shopping cart through a simulated shopping route. Data were collected on the mean and maximum pressure. Qualitative data were collected the on participants’ description of comfort based on their handle diameter preference. The Main Conclusions of High Quality Articles That Examined Subjective Assessments. Name of Assessment Burn Scar Surgical Scar Mixed Scar Conclusion based on high quality articles (overall quality scores 70%) Patient Observer Scar Assessment Scale (POSAS) Simons et al [38] (87.5%) Truong et al [45] (87.5%) Van der Kar et al [47] (71.1%) Internal consistency of the POSAS Observer and Patient scales was good. All of the individual items in the POSAS Observer Scale demonstrated acceptable reliability. POSAS Patient Scale demonstrated good intra-rater reliability for the individual items as well as the total score. Manchester Scar Scale (MSS) Simons et al [38] (87.5%) “Contour” and “Color” parameters of the MSS demonstrated good reliability. Modified Vancouver Scar Scale (mVSS) Simons et al [38] (87.5%); Gankande et al [20] (70%) Nedelec et al [34] (72.9%) The findings from three high quality articles are inconsistent, demonstrating high and low reliability ratings for all of the individual items in the assessment. Patient Scar Assessment Scale e French (PSAS-Fr) Deslauriers et al [12] (75%) Good cross-sectional properties when compared to the English version. Specifically, it demonstrates high internal consistency, inter-rater reliability, concurrent validity, and content validity. However, the results are only generalizable to French speaking Canadians. Patient Scar Assessment Questionnaire (PSAQ) Durani et al [1] (73%) Demonstrated moderate convergent validity with POSAS. Good internal consistency. Inconsistency present in the inter-rater reliabilities of the individual subscales, and was shown to be low for certain types of scars (i.e. nevi excision, scar revision). % indicated is SEQES quality score /100 The shopping cart with secured weights and alternative handles to simulate the weight of a typical grocery load.
