Abstract Background: Powered equipment for patient handling was designed to alleviate Emergency Medical Service (EMS) clinician injuries while lifting patients. This project evaluated the organizational rationale purchasing powered and outcomes from use. Methods: analyzed secondary data obtained via an insurance Safety Intervention Grant (SIG) program in Ohio USA. These were primarily reports EMS organizations. Investigators applied a mixed-methods approach, analyzing quantitative 297 grants...

The objective of this study was to assess the accuracy an algorithm for processing data from five inertial measurement unit (IMU) sensors measuring vertical distance (V) and horizontal (H) two handed lifting, trunk flexion angle (T) lifting duration (LD). were placed on body segments including left wrist, right upper arm dominant hand, back, thigh leg. A laboratory-grade optical motion capture system used as ground truth assessment. Data collected ten subjects that performed 12 two-handed...

Occupationally-induced back pain is a leading cause of reduced productivity in industry. Detecting when worker lifting incorrectly and at increased risk injury presents significant possible benefits. These include quality life for the due to lower rates fewer workers’ compensation claims missed time employer. However, recognizing provides challenge typically small datasets subtle underlying features accelerometer gyroscope data. A novel method classify dataset using 2D convolutional neural...

This paper presents a review of 153 case studies equipment interventions to improve safety and health construction businesses in Ohio 2003–2016. These represent $6.46 million (2016 USD) purchases incentivized through the Bureau Workers' Compensation (OHBWC) Safety Intervention Grant (SIG) program. The source data were extracted from employer grant applications final reports studies. Results aggregated by type included reduction ergonomic hazards (risk factors for work-related musculoskeletal...

Objective A computer vision method was developed for estimating the trunk flexion angle, angular speed, and acceleration by extracting simple features from moving image during lifting. Background Trunk kinematics is an important risk factor lower back pain, but often difficult to measure practitioners lifting assessments. Methods Mannequins representing a wide range of hand locations different postures were systematically generated using University Michigan 3DSSPP software. bounding box...

Abstract This article reviews the experiences of 63 case studies small businesses (<250 employees) with manufacturing automation equipment acquired through a health/safety intervention grant program. The review scope included technologies classified as industrial robots ( n = 17), computer numerical control (CNC) machining 29), or other programmable systems 17). Descriptions workers' compensation (WC) claim injuries and identified risk factors that motivated acquisition were extracted...

The objective of this study was to develop an algorithm for automatically processing data collected with inertial measurement unit (IMU) wearable devices measure lifting risk factors low back disorders. Five IMU sensors attached five body segments were used developing the algorithm. consists two modules running in parallel detecting beginning and ending a event as well vertical height (V) object lifted by hands horizontal (H) distance between during lift. motion synchronization feature...

The American Conference of Governmental Industrial Hygienists (ACGIH) Threshold Limit Values (TLVs) for lifting provides risk zones assessing two-handed tasks. This paper describes two computational models identifying the using gyroscope information from five inertial measurement units (IMUs) attached to lifter. Two were developed: (1) ratio model body segment length ratios forearm, upper arm, trunk, thigh, and calf segments, (2) + actual measurements segments in model. evaluated data 360...

We previously developed a method for classifying lifting postures using dimensions of rectangular bounding box drawn tightly around the subject single camera view that is more tolerable conditions encountered in industrial settings than high precision tracking and can be practically implemented on smart hand-held device. This study explores use simple to predict trunk angle while lifting. Mannequin poses were generated Michigan 3DSSPP software 105 across six anthropometries. A regression...

The purpose of this study was to assess two computation models for estimating the hand locations during lifting tasks using data from five inertial measurement units (IMUs) attached body segments. first model computed location with IMU gyroscope and pre-defined ratios segment lengths. second used same information all measured lengths outcome measure these estimated in 12 zones defined by ACGIH Threshold Limit Values (TLVs) lifting. Motion collected wearable system a laboratory-grade motion...

Healthcare providers face numerous challenges in lifting and mobilizing overweight obese patients, which often lead to musculoskeletal disorders (MSDs). To address this, hospitals implement safe patient handling mobility (SPHM) programs, including mechanical lift equipment, policies, training. This study surveyed 134 healthcare workers five Veterans Administration Medical Centers who regularly used SPHM programs. According findings, bariatric patients frequently correlated with higher...
