“…Numerous other data sets contain 5 and 95 % tile for a broad range of humans (Opeshaw and Taylor 2006). Lin et al (2006) reported that manual material handling (MMH) especially lifting represents a major occupational safety and health risk in places such as industries and hospitals. Musculoskeletal and low-back disorders are often attributed to over exertion of the body when the operator works to meet the demand of MMH tasks.…”

Hospital meal carts are used to deliver meals, drugs and some other materials to patients in the hospital environment. These carts which are moved manually by operators, the health workers, mostly do not comply with ergonomics guidelines and physical requirements of the equipment users in terms of anthropometry data of the region thus increasing the risk of musculoskeletal disorder among the meal cart users. This study carried out ergonomic evaluation of the available meal carts in some western Nigeria hospitals. A well-structured questionnaire has two major segments: Operational survey and biomechanical survey, which were administered to the health workers using hospital meal carts in some hospitals in southwestern Nigeria, and physical assessment, which was undertaken to collect data for the ergonomic evaluation. The responses from the questionnaires show that some areas on the existing hospital meal carts are of concern to the users which need to be improved upon.

“…1) lifting, elbow flexion, wrist extension, and ulnar deviation are clinically relevant. The following average ranges of motion were recorded for each joint: 50° for arm lifting (5° difference between the conditions), 56° for elbows (6° difference between the conditions), 38° for wrist extension (4° difference between the conditions), and 31° for ulnar deviation of the wrist (3° difference between the conditions).…”

| Background: The handling of materials, which occurs in the industrial sector, is associated with lesions on the lumbar spine and in the upper limbs. Inserting handles in industrial boxes is a way to reduce work-related risks. Although the position and angle of the handles are significant factors in comfort and safety during handling, these factors have rarely been studied objectively. Objective: To compare the handling of a commercial box and prototypes with handles and to evaluate the effects on upper limb posture, muscle electrical activity, and perceived acceptability using different grips while handling materials from different heights. Method: Thirty-seven healthy volunteers evaluated the handles of prototypes that allowed for changes in position (top and bottom) and angle (0°, 15°, and 30°). Wrist, elbow, and shoulder movements were evaluated using electrogoniometry and inclinometry. The muscle electrical activity in the wrist extensors, biceps brachii, and the upper portion of the trapezius was measured using a portable electromyographer. The recorded data on muscle movements and electrical activity were synchronized. Subjective evaluations of acceptability were evaluated using a visual analog scale. Results and Conclusions: The prototypes with handles at a 30° angle produced the highest acceptability ratings, more neutral wrist positions, lower levels of electromyographic activity for the upper trapezius, and lower elevation angles for the arms. The different measurement methods were complementary in evaluating the upper limbs during handling.Keywords: ergonomic design; usability; electrogoniometry; electromyography; grip perception.

“…A second and not negligible aspect is the exposure of single health care, that is calculated on the basis of a "presumed" patients handling, and not on the direct observation of quality and quantity of handling operations (impossible thing). The advanced hypothesis implies that in all situations, where not self-sufficient patients are present, all health workers perform a substantially homogeneous activity, with a minimum number of lifts-shifts, as for example the personal hygiene operations (36)(37)(38)(39)(40)(41).…”

SummaryBackground: the necessity to help hospitalized subjects with reduced or absent walking abilities exposes the workers to the risk of lesions, above all spinal lesions. It is essential therefore to reduce the risk through the introduction of correct procedures and devices as well as health surveillance and training. The Mapo index is a synthetic index to estimate the manual handling of patients assessment and it allows to give a quantitative valuation of risk level of health workers. Objectives: to assess the incidence of musculoskeletal disorders of the spinal in subjects exposed to different risk classes, correlating it with the MAPO index. Methods: we identified 53 male subjects more exposed and 26 male subjects less exposed and also 72 female subjects more exposed and 36 female subjects less exposed. These groups were made comparable as for age, working seniority, BMI and sport activities. The classification for spondyloarthropathies (SAP) indicated by the SIMLII Guidelines for the prevention of disorders and musculoskeletal diseases of the spine by manual handling of loads was carried out. The statistical analysis of data was based on the calculation of the mean, standard deviation, distribution, frequency, and range according to the single variables. The differences between averages were compared using Student T-test for continuous data and χ²-test for dichotomous data. Results: the results we obtained by comparing mean and standard deviation, gave p > 0.05. The comparison made through the χ²-test showed no significance because the p was always > 0.05. In the end, the analyzed data showed no statistically significant correlation between musculoskeletal diseases and the classification of workers in the relative risk class. Discussion and Conclusions: in our research the MAPO index did not turn out to be an exposure index correlated to a specific disease, because the workers at higher risk of band, compared to the workers at lower risk, use probably more correct procedures concerning the handling of hospitalized patients, conversely it can be supposed that there are less severe procedures and less compliance for the category of workers at lower risk.
