Analysis

The Revised Upper Extremity Work Demands Scale (RUEWDS) is designed to assess the demands and loads associated with the use of the upper extremities (arms and hands) in the workplace. The scale focuses on factors such as repetitive use, lifting, pressure, and other physical demands that affect the functionality and health of the upper limbs.

Objective

The primary objective of the RUEWDS is to evaluate the physical demands placed on workers’ upper extremities in order to understand their impact on individuals’ well-being and health. The scale helps identify occupational risks related to physical labor and provides data for developing prevention and intervention strategies aimed at reducing musculoskeletal injuries and fatigue.

Scoring

The RUEWDS includes a series of statements rated on a Likert scale, typically from 1 to 5, to assess the frequency of upper limb use, repetitive movements, lifting, strain from postures, resistance, and pressure. The overall score is derived by summing the ratings of the individual items, with higher scores indicating greater demands and load.
