“…However, workers may need time to familiarize with the new tools [ 249 ]. Moreover, ergonomic educational training making the worker aware of the risks and physical exercise programs showed improved working postures, reducing muscle activity and musculoskeletal complaints [ 214 , 239 ]. These interventions improve both physical and mental health [ 250 ] and are thus beneficial for workers [ 318 ].…”

“…Very few studies did not find FSE in the working tasks [ 117 , 136 ]. Another group of studies identified ergonomic interventions, such as new ergonomic workstations [ 243 ], tools [ 229 ] or training programs [ 239 ] that could be implemented in order to improve the working postures and reduce FSE. Other studies proposed exoskeletons or supporting devices in order to reduce the FSE, especially in prolonged posture maintenance and overhead working tasks [ 259 , 263 ] that require high loads on the neck, back and shoulder [ 261 ].…”

Biomechanical Assessments of the Upper Limb for Determining Fatigue, Strain and Effort from the Laboratory to the Industrial Working Place: A Systematic Review

Recent human-centered developments in the industrial field (Industry 5.0) lead companies and stakeholders to ensure the wellbeing of their workers with assessments of upper limb performance in the workplace, with the aim of reducing work-related diseases and improving awareness of the physical status of workers, by assessing motor performance, fatigue, strain and effort. Such approaches are usually developed in laboratories and only at times they are translated to on-field applications; few studies summarized common practices for the assessments. Therefore, our aim is to review the current state-of-the-art approaches used for the assessment of fatigue, strain and effort in working scenarios and to analyze in detail the differences between studies that take place in the laboratory and in the workplace, in order to give insights on future trends and directions. A systematic review of the studies aimed at evaluating the motor performance, fatigue, strain and effort of the upper limb targeting working scenarios is presented. A total of 1375 articles were found in scientific databases and 288 were analyzed. About half of the scientific articles are focused on laboratory pilot studies investigating effort and fatigue in laboratories, while the other half are set in working places. Our results showed that assessing upper limb biomechanics is quite common in the field, but it is mostly performed with instrumental assessments in laboratory studies, while questionnaires and scales are preferred in working places. Future directions may be oriented towards multi-domain approaches able to exploit the potential of combined analyses, exploitation of instrumental approaches in workplace, targeting a wider range of people and implementing more structured trials to translate pilot studies to real practice.

“…Gloves can have disadvantages such as reduced dexterity and manual sensitivity and can change the dimensions of the hand to the point of interfering with a person's handling ability (Cabeças & Milho, 2011). Such difficulties are clearer in operations with micro tractors in which the operator constantly changes the intensity of hand contact with the source of vibration, the handle, when handling the machine for ensuring that it is aligned to the direction of soil preparation.…”

ABSTRACT During the working day, agricultural machinery operators are often exposed to physical risks, such as vibration, which can compromise their health and performance. Micro tractors emit high levels of vibration, which mainly affect their hands and arms. Thus, this study aims at evaluating the efficiency of different glove models in reducing vibration transmitted by the micro tractor/rotary tiller assembly according to the operating velocity and the rotation of the rotary tiller rotor. A completely randomized block design was used in a 4 x 2 x 2 factorial arrangement with five replicates. The study analyzed three glove models (G1 and G2 anti-vibration models, and anti-impact model G3) and a control treatment under the same operating conditions, but without the use of protective equipment. The study was conducted at two operating velocities (V1 = 0.98 km h-1 and V2 = 1.6 km h-1) and two rotations of the rotary tiller rotor (R1 = 265 rpm and R2 = 520 rpm). None of the evaluated glove models reached the attenuation capacity required by the Occupational Hygiene Standard (Norma de Higiene Ocupacional - NHO 10) and, under some operating conditions, they raised the incident vibration levels, exceeding the values obtained when the work was performed without a protective equipment. Although the anti-impact model G3 and the anti-vibration model G2 did not reduce the transmitted vibration to the levels considered acceptable by NHO 10, the anti-impact G3 and anti-vibration G2 models showed better performance in the work performed at a velocity of 0.98 km h-1 and a rotation of 520 rpm of the rotary tiller rotor.

Preliminary identification and evaluation of parameters affecting the capacity of the operator-earthmoving machine system

et al. 2013

Without reliable data on the time of work of construction machines it is impossible to calculate the cost of the investment or the time limit for its implementation. Machine capacity is affected by many factors resulting from both the technical capabilities of a machine (e.g. the engine and bucket capacity) and work environment (e.g. soil loosening and weather conditions). Capacity is also influenced by factors affecting the operator (e.g. health condition, stress, fatigue). Therefore, it is appropriate to use the concept of the operator-machine system. The current system for the standards of machine working time collected in catalogues of capital expenditures is outdated (a lack of modern materials, technology and equipment currently used). It does not take into account all possible weather conditions, labour conditions and soil and water conditions. The result of this state of affairs may be overestimation or underestimation of an investment. On the basis of the conducted research it may be concluded that the greatest impact on the capacity of the operator-earthmoving machine system is exerted by parameters associated with the psychophysical condition of the operator (experience, fatigue, health and motivation of the operator) and the technical parameters of the machine (technical condition and theoretical technical capacity). Weather conditions, particularly air humidity, affect the performance to the smallest extent.
