3.1.5. Construction

Table 7 presents studies conducted in the construction field using RULA.


### **Table 7.** Construction.

Shanahan et al. [132] analysed the usefulness of three assessment methods (RULA, REBA and the Strain Index) when used in non-fixed tasks and comparing them with four psychophysical scales from Borg 10. Fourteen construction workers without MSD were followed up. They concluded that the best method for this type of task was the Strain Index.

Another study proposed a more accurate way of measuring the angles in the postures adopted by construction workers in order to use the RULA method [131].

Finally, Li et al. [129,130] also focused on the field of construction. They developed a 3D system that allows one to simulate the working environment and perform an ergonomic assessment. They also applied REBA and RULA for the analysis.

3.1.6. Wholesale and Retail Trade; Repair of Motor Vehicles and Motorcycles

In this category, only three studies are presented (Table 8).

**Table 8.** Wholesale and retail trade; repair of motor vehicles and motorcycles.


Wholesale and Retail Trade and Repair of Motor Vehicle and Motorcycles

Risk factors and the onset of MSD were studied in car repair mechanics. In total, 191 workers participated. The modified Nordic Questionnaire was used with RULA, in addition to other tools. Most workers were shown to have this type of disorder [133].

Retail Trade, Except Motor Vehicles and Motorcycles

Capodaglio [134] conducted an ergonomic study on 70 clothing store vendors. RULA, REBA, the Strain Index and OCRA were used. The results showed a high risk in the upper extremities for the postures adopted. Another study was carried out at supermarket check-outs. A tool was developed to carry out a postural assessment of the workers. It was a portable and wireless system based on RULA and the Strain Index. It allowed the assessment to be performed as the task was being undertaken [135].

3.1.7. Transportation and Storage

Table 9 contains the studies available in the Transportation and Storage category.
