Validity and reliability of a new device to simulate upper extremity work demands

Area of Science:

• Occupational health
• Biomechanical engineering
• Ergonomics

Background:

• Assessing physical capacity is crucial in occupational settings.
• The LIDO WorkSET(TM) is a device used for such assessments.
• Reliability and validity are key metrics for any assessment tool.

Purpose of the Study:

• To evaluate the device validity of the LIDO WorkSET(TM).
• To determine the intra-test and test-retest reliability of the LIDO WorkSET(TM) protocols.
• To assess the stability of inter-test comparisons over time.

Main Methods:

• Thirty healthy workers from a manufacturing and warehousing facility participated.
• The study assessed device validity for torque, power, and work measurements.
• Intra-test and test-retest reliability were analyzed using established protocols.

Main Results:

• The LIDO WorkSET(TM) demonstrated very high device validity for torque, power, and work.
• Testing protocols exhibited strong reliability on both intra-test and inter-test bases.
• Inter-test comparisons remained stable when assessed over time.

Conclusions:

• The LIDO WorkSET(TM) is a valid and reliable tool for assessing physical capacity in occupational settings.
• The study confirms the consistency and stability of the device and its testing protocols.
• Findings support the use of LIDO WorkSET(TM) in manufacturing and warehousing environments.
