Can Exoskeletons Reduce Musculoskeletal Disorders in Healthcare Workers?

Musculoskeletal Disorders (MSDs) remain a major concern for workers in the healthcare industry. Healthcare workers are at high risk of work-related MSDs mainly caused by overexertion from lifting and moving patients (i.e., patient handling). Wearable robots—exoskeletons or exosuits—may be a useful tool to help reduce risk of MSDs during patient handling. Background Based on the Read More >

Introducing an Occupational Health Resource: The Occupational Noise Job Exposure Matrix

Introduction Noise-induced hearing loss is highly prevalent in the U.S., and noise is increasingly being linked to other non-auditory health effects such as cardiovascular disease, sleep disturbance, and stress. However, our knowledge of noise exposures associated with many U.S. occupations is lacking. To address this issue, researchers used existing resources to develop a first-of-its-kind Job Read More >

Protecting Machine Operators from Silica Dust: Enclosed Cabs

  Construction workers who operate heavy equipment such as excavators, bulldozers, cranes, and backhoes frequently generate large quantities of respirable crystalline silica (RCS) dust. Exposure to even small amounts of RCS over time can cause silicosis, lung cancer, or chronic obstructive pulmonary disease (COPD), and other serious diseases. A recent study published in the American Read More >
