Project Descriptions

Selected Research Projects are described below.

Decision Support System for Ergonomic Construction Design: Phase II

Sponsor:  National Institute for Occupational Safety and Health (NIOSH)

PI:           Maury A. Nussbaum            Co-Is:   John P. Shewchuk and Michael J. Agnew

Goals:     

  • Develop a decision-support system for use by residential construction designers and/or builders, for applications using prefabricated walls (panels)
  • Create panel designs, stacking, and construction plans that enhance both ergonomics and productivity
  • Generate designs and plans rapidly and in a consistent, documented manner

Ergonomic Research on Manufacturing Tasks

Sponsor:  Equipois, Inc.

PI:            Maury A. Nussbaum            Co-I:   Michael J. Agnew

Goals:      

  • Determine whether and to what extent the use of a Wearable Assistive DEvice (WADE) can reduce operator physical stress during overhead work, compared to manual methods
  • Determine whether the benefits of the WADE are dependent on specific payloads

Evaluation of Patient Handling Devices

Sponsor:  Stryker Medical

PI:            Maury A. Nussbaum            Co-I:   Michael J. Agnew

Goal:        

  • Assess the effects of hospital bed design features on physical demands, performance, and usability during patient transportation and patient handling tasks

Occupational Trunk Flexion and Neuromuscular Disturbance

Sponsor:  National Institute for Occupational Safety and Health (NIOSH)

PI:            Maury A. Nussbaum            Co-I:   Michael L. Madigan

Goals:      

  • Assess the viscoelastic responses of the lumbar spine to prolonged and/or repetitive spine flexion and lifting activities
  • Determine how spine flexion influences muscle reflex behaviors and spine stability
