“…At the end of each day each photograph was printed in A4 size, after which each participant's actual deviations from the plumb line were measured with a ruler with increments in millimetres, and transferred to data forms. The actual (real) distance on photos was established by calculating the ratio of measured/real distance x distance from plumb line for each photo 32 . A clinical significant difference from the reference point as measured on the photo was set at 10mm 33 and percentages for categorical data, and medians and percentiles for numerical data, were calculated.…”

Results from a study 16 that investigated the difference of sensed posture using open kinetic chain and closed kinetic chain (CKC) found a mean error of 5,5 o and concluded that the mean error in sensed posture is less in CKC. Cheuh-Ho Lin et al. 21 proved an insignificant mean error of 0.6 o for sensed posture in healthy ankles. Olson, et al. 15 found that contralateral assessment showed a greater mean error than ipsilateral assessment. Brindle et al. 22 states that visual feedback enhances sensed posture, while Gibson 23 proved vision to be more dominant than touch and proprioception. Far less research evidence is available on sense of position of the shoulder and elbow joints. Correlation between sensed posture position and sensed posture error 12 between shoulder and elbow joint indicates similar errors in sensed posture and further indicate that sensed posture error decreases nearing end-range of motion. King, Harding and Karduna 14 further found no significant differences in sensed posture between left and right upper extremity joints, and proved that the mean error for the shoulder joint was greater than the elbow joint.Unpublished research findings 24 indicate that whole body posture (multi-joint), sense of posture is more accurate in anterior planes than in the lateral planes, and that the number of participants with actual deviation in posture is more than the number of participants who sensed a deviation in their postural alignment. ABSTRACTIntroduction: Accurate sensing of the body position in space is important for safe and mechanically effective interaction with the environment. Clinical evidence however suggests that a client's sense of postural alignment differs from their actual alignment, which may influence the accuracy of postural repositioning during participation in activities of daily life.Objectives: The aim of this quantitative descriptive study was to investigate the difference between sense and actual postural alignment during sitting and standing positions, with the anatomical landmarks as reference points for measurement from anterior and lateral views.Methods: Ten health care clinics in the Free State towns of Botshabelo and Thaba N'chu, were randomly selected and 95 patients participated in the study. Measurements consisted of (a) a biographical questionnaire, (b) assessment of actual postural alignment, and (c) assessment of sensed postural alignment. Assessment of actual postural alignment was done by using the Photographic Method of Postural Assessment (P-MPA), during which the actual (real) distance on photos was established by calculating the ratio of measured/ real distance x distance from plumb line for each ph...

Importance: Work-related musculoskeletal disorders (WMSDs) among surgeons are markedly increasing. Several proposed interventions to reduce WMSDs among surgeons have been studied, but few follow an occupational therapy–oriented approach addressing biomechanical, psychophysical, and psychosocial risk factors. Objective: To design, implement, and assess the potential of the Comprehensive Operating Room Ergonomics (CORE) program for surgeons, a holistic evidence-based ergonomics and wellness intervention grounded in occupational therapy principles. Design: Mixed-methods pilot study with the quantitative strand embedded in the qualitative strand. Setting: University-affiliated hospital. Participants: Six laparoscopic surgeons. Outcomes and Measures: CORE program outcomes were assessed using qualitative and quantitative data to indicate changes in posture, physical discomfort, sense of wellness, and operating room (OR) ergonomic performance. The Rapid Upper Limb Assessment (RULA) was used to quantify surgeons’ WMSD risk level before and after intervention. Results: There were 12 baseline observations (two for each participant), and two or three post-CORE implementation observations. A statistically significant difference, F(1, 6) = 8.57, p = .03, was found between pre– and post–occupational therapy intervention RULA scores. Thematic analysis of surgeon feedback, which was overwhelmingly positive, identified five themes: postural alignment, areas of commonly reported physical pain or discomfort, setup of the OR environment, surgical ergonomics training, and ergonomics in everyday life. Conclusions and Relevance: The CORE program effectively decreased ergonomic risk factors to optimize surgeons’ occupational performance in the OR. This study demonstrates a potential solution to how occupational therapists can holistically support surgeons and health care providers who are at risk for WMSDs. Plain-Language Summary: By 2025, a surgeon shortage is expected, partly because of the increase in surgeons’ work-related musculoskeletal disorders, which affect their health and job continuity. This pilot study shows that the Comprehensive Operating Room Ergonomics program effectively addresses these problems. The study also serves as a framework for occupational therapy professionals to work with health care providers on ergonomics, benefiting population health. Results suggest that this approach could enhance surgeons’ work conditions, supporting the American Occupational Therapy Association’s Vision 2025 to improve health and quality of life.
