Journal of Engineering Project and Production Management · 2023

Key Findings

01A novel framework for assessing DUED risk in hand-intensive tasks has been developed.
02The framework allows for direct evaluation of exoskeleton efficacy in mitigating DUED risk.
03Exoskeletons show potential for significant reduction in DUED risk.

Application

Design takeaway

How to apply

Use the developed framework to conduct ergonomic risk assessments for tasks involving repetitive hand motions and force, and then evaluate the potential reduction in risk with exoskeleton use.

Project actions

01When researching assistive devices, focus on how they directly impact human physiology and reduce strain.
02Develop a clear methodology for measuring the effectiveness of your design interventions.

Method & Evidence

AimTo develop and validate a framework for directly assessing the impact of exoskeletons on reducing the risk of distal upper extremity disorders (DUED) in construction tasks.

MethodFramework Development and Application

ProcedureResearchers adapted the Hand Activity Level Threshold Limit Value process to create a specific framework for assessing DUED risk. This framework was then used to evaluate the efficacy of an exoskeleton in reducing DUED risk during hand-intensive construction activities.

ContextConstruction industry, manual labor, occupational health and safety.

Variables

IVUse of exoskeleton (Yes/No).

DVDUED risk score, measures of muscle activation or strain.

CVType of construction task, duration of task, environmental conditions, worker experience level.

Strengths & Limitations

Strengths

+Directly addresses the impact of exoskeletons on DUED, a gap in previous research.
+Provides a practical, adaptable framework for risk assessment.

Limitations

The specific tasks and types of exoskeletons studied might not be universally applicable to all construction environments.

Reliability & validity

The framework's validity relies on its ability to accurately predict or measure DUED risk, while reliability would be assessed by consistent results when applied to similar tasks and worker groups.

Think critically

How might the effectiveness of exoskeletons vary across different construction trades or individual worker anthropometrics, and how could the proposed framework be adapted to account for these variations?

Design Principles

"Quantify the impact of assistive technologies on human physical strain to validate their ergonomic benefits."

This research provides a quantifiable method for assessing the effectiveness of exoskeletons as a safety intervention. Designers and safety professionals can use this framework to justify the adoption of such technologies, leading to improved worker well-being and potentially reduced healthcare costs and lost workdays in physically demanding industries.

What This Means for Your Design

Wearing special arm/hand supports (exoskeletons) can help construction workers avoid getting painful hand and wrist problems because it takes some of the strain off their muscles.
