Abstract

Breast cancer affects one in 8 females with a 5-year survival rate of 89%. Up to 72% of breast cancer survivors have trouble with activities of daily living (ADL) following treatment. Increased time-from-treatment improves some measures of function, yet ADL limitations persist. Therefore, this study assessed the effect of time-from-treatment on upper extremity kinematics during ADLs in breast cancer survivors. Twenty-nine female breast cancer survivors were divided into 2 groups: <1 year (n = 12) and 1–2 years (n = 17) from treatment. Kinematics were collected during 6 ADL tasks, and humerothoracic joint angles were quantified. A 2-way mixed analysis of variance assessed the effects of time-from-treatment and arm on maximum angles for each ADL. Decreased maximum angle existed for breast cancer survivors with increased time-from-treatment during all ADLs. Breast cancer survivors in the 1–2 years group used ∼28° to 32° lower elevation, ∼14° to 28° lower axial rotation, and ∼10° to 14° lower plane of elevation range across tasks. Decreased ranges of arm movement during ADLs with increased time-from-treatment may reflect compensatory movement strategies. Recognizing this shift in strategies and accompanying underlying disease progression can help inform responses to functional performance limitations in breast cancer survivors as delayed effects are present posttreatment.

18. The benefits of advanced exposure metrics to estimate occupational shoulder demands

Abstract

Physical exposure assessment is a critical component of ergonomic analysis in occupational settings. This work used a computational model to obtain quantitative measures of shoulder moment, glenohumeral joint contact force and rotator cuff muscle demand based on recorded postures and manual force estimates during the performance of ten different occupational tasks. Outcomes of simulation analyses demonstrated that advanced model outputs can enhance resolution of shoulder-specific exposures currently unavailable with standard ergonomics assessment techniques. A novel composite injury risk score effectively discriminated between shoulder exposure levels. It includes multiple complementary parameters into a single exposure risk assessment tool. The major contribution of the work is to establish the feasibility and utility of incorporating a computational model into ergonomic assessments across occupational tasks.
