2005 article

Adaptive system identification applied to the biomechanical response of the human trunk during sudden loading

Lawrence, B. M., Mirka, G. A., & Buckner, G. D. (2005, January 9). Journal of Biomechanics.

By: B. Lawrence n, G. Mirka n & G. Buckner n

author keywords: sudden loading; fatigue; training; lumbar; injury; modeling
MeSH headings : Abdomen / physiology; Acceleration; Adaptation, Physiological / physiology; Adult; Biomechanical Phenomena / methods; Computer Simulation; Elasticity; Head / physiology; Humans; Lumbar Vertebrae / physiology; Male; Models, Biological; Movement / physiology; Muscle Contraction; Muscle, Skeletal / physiology; Postural Balance / physiology; Posture / physiology; Stress, Mechanical; Thorax / physiology; Torque; Weight-Bearing / physiology
topics (OpenAlex): Musculoskeletal pain and rehabilitation; Balance, Gait, and Falls Prevention; Effects of Vibration on Health
TL;DR: time-varying loading of the spine during sudden loading events and how these loading profiles are affected by workplace factors such as fatigue, expectation, and training can potentially lead to intervention strategies that can reduce these risks. (via Semantic Scholar)

2005 article

An Adaptive System Identification Model of the Biomechanical Response of the Human Trunk During Sudden Loading

Lawrence, B. M., Buckner, G. D., & Mirka, G. A. (2005, November 3). Journal of Biomechanical Engineering.

By: B. Lawrence n, G. Buckner n & G. Mirka n

author keywords: sudden loading; system identification; lumbar
MeSH headings : Abdomen / physiology; Adaptation, Physiological / physiology; Adult; Back / physiology; Biomechanical Phenomena / methods; Computer Simulation; Elasticity; Feedback / physiology; Humans; Male; Models, Biological; Movement / physiology; Postural Balance / physiology; Posture / physiology; Reflex / physiology; Thorax / physiology; Weight-Bearing / physiology
topics (OpenAlex): Occupational Health and Performance; Musculoskeletal pain and rehabilitation; Effects of Vibration on Health
TL;DR: System identification can be implemented with minimal error and used to gain more insight into the time-dependent trunk response to sudden loads and show estimates of system stiffness in good agreement with values in the literature. (via Semantic Scholar)

2001 article

An investigation of the effects of touchpad location within a notebook computer

Kelaher, D., Nay, T., Lawrence, B., Lamar, S., & Sommerich, C. M. (2001, February 1). Applied Ergonomics.

By: D. Kelaher n, T. Nay n, B. Lawrence n, S. Lamar n & C. Sommerich n

author keywords: notebook computer; pointing device; wrist posture; musculoskeletal discomfort
MeSH headings : Adult; Analysis of Variance; Elbow / physiopathology; Equipment Design / instrumentation; Ergonomics; Female; Humans; Male; Microcomputers; Shoulder / physiopathology; United States; User-Computer Interface; Wrist / physiopathology
topics (OpenAlex): Ergonomics and Musculoskeletal Disorders; Color perception and design; Spatial Cognition and Navigation
TL;DR: Touchpad location was found to significantly impact upper extremity posture, discomfort, preference, and performance, and the top center location was particularly poor, in that it elicited more ulnar deviation, more shoulder flexion, more discomfort, and perceptions of performance impedance.

Continuous Assessment of Back Stress (CABS): A New Method to Quantify Low-Back Stress in Jobs with Variable Biomechanical Demands

Mirka, G. A., Kelaher, D. P., Nay, D. T., & Lawrence, B. M. (2000, June 1). Human Factors The Journal of the Human Factors and Ergonomics Society.

By: G. Mirka n, D. Kelaher n, D. Nay n & B. Lawrence n

MeSH headings : Back / physiology; Back Injuries / etiology; Biomechanical Phenomena; Cumulative Trauma Disorders / etiology; Data Interpretation, Statistical; Female; Humans; Male; Models, Theoretical; National Institute for Occupational Safety and Health, U.S.; Occupational Diseases / etiology; Occupations; Risk Assessment; Stress, Physiological / etiology; Task Performance and Analysis; United States; Workload
topics (OpenAlex): Musculoskeletal pain and rehabilitation; Occupational Health and Safety Research; Ergonomics and Musculoskeletal Disorders
TL;DR: A hybrid assessment methodology that employs established assessment tools and then represents their evaluations in a way that emphasizes the distributions of biomechanical stress is developed, illustrating the necessity for more advanced low-back injury risk assessment techniques for jobs with highly variable manual materials handling requirements.
