A Logistic Regression Model for Biomechanical Risk Classification in Lifting Tasks.

Lifting is one of the most potentially harmful activities for work-related musculoskeletal disorders (WMSDs), due to exposure to biomechanical risk. Risk assessment for work activities that involve lifting loads can be performed through the NIOSH (National Institute of Occupational Safety and Health) method, and specifically the Revised NIOSH Lifting Equation (RNLE). Aim of this work is to explore the feasibility of a logistic regression model fed with time and frequency domains features extracted from signals acquired through one inertial measurement unit (IMU) to classify risk classes associated with lifting activities according to the RNLE.

Exergame for the functional rehabilitation of adults over 55 with neurological diseases.

Rehabilitation based on Exergame is showing a rapid evolution, with interesting applications for the recovery of mobility, balance, postural control, coordination and fine motor skills, and including home-based training. At present, there are no precise indications for Exergamebased rehabilitation of people over 55 affected by stroke, Parkinson's disease, or multiple sclerosis. This review examines the proposed modalities and the effectiveness of Exergame-based rehabilitation interventions for adults over 55 with stroke, Parkinson's disease or multiple sclerosis, highlighting the limitations, advantages, controversies and impact of this approach.

A multiple linear regression approach to extimate lifted load from features extracted from inertial data.

Work-related musculoskeletal disorders are among the main occupational health problems. Substantial evidence has shown that work-related physical risk factors are the main source of low back complaints, particularly affecting heavy and repetitive manual lifting activities. The aim of the study is, during load lifting tasks, to explore the correlation between the time domain features extracted from the acceleration and angular velocity signals of the performing subject and the load lifted, and to explore the feasibility of a multiple linear regression model to predict the lifted load.

Artificial Neural Network Analyzing Wearable Device Gait Data for Identifying Patients With Stroke Unable to Return to Work.

A potential dramatic effect of long-term disability due to stroke is the inability to return to work. An accurate prognosis and the identification of the parameters inflating the possibility of return to work after neurorehabilitation are crucial. Many factors may influence it, such as mobility and, in particular, walking ability.

Return to Work and Quality of Life after Stroke in Italy: A Study on the Efficacy of Technologically Assisted Neurorehabilitation.

Cerebrovascular diseases, including stroke, are historically considered diseases of old adults so only in a few studies has "return to work" (RTW) been considered as an index of rehabilitative outcome. At the moment, data on RTW in patients with stroke are highly variable: four different reviews reported the following ranges: 11-85%, 19-73%, 22-53%, and 40-45%. The absence of re-integration to work after a stroke is shown to be associated with an increase of cardiac disorders and depression, with a higher level of mortality, with social isolation and with insufficient adaptive skills.

Participatory ergonomics for the reduction of musculoskeletal exposure of maintenance workers.

Exposure to musculoskeletal disorders (MSDs) is a prevalent risk among those working in the maintenance of machinery and equipment for industry. Participatory ergonomics (PE) in the workplace embodies a solid strategy for the implementation of MSD prevention programs. This practical case describes a PE project implemented to improve MSD prevention strategies for the safety of maintenance workers Experienced workers and maintenance workers employed in an Italian company for the industrial processing of wool have been actively involved in the risk assessment, in the proposal of improvement interventions and in the proposal of new preventive strategies.

[Active population aging, ICD-ICF clinical model and Occupational and Rehabilitation Medicine].

The aging of the active population is more and more increasing in advanced western societies. This phenomenon also implies a constant increase in the average age of workers in various productive sectors, not least that of health. In this, in fact, alongside the known occupational risks, more and more frequently we are witnessing the emergence of chronic-degenerative pathologies connected with aging, even with symptoms that do not determine an unsuitability for work.

[The ICD-ICF outpatient pathway in occupational therapy].

The Complex Ambulatory Macroactivity (MAC, Macroattività Ambulatoriale Complessa) has recently been included among the therapeutic and diagnostic Specialized Rehabilitation services issued by the Lombardy Region health institutes. Within Maugeri Scientific Clinical Institutes, our Occupational Physiatrics and Ergonomics Service is actively involved in the organic redefinition of rehabilitative pathways in the light of functional and patient-centered interpretation, typical of ICF (International Classification of Functioning). The article describes the assumptions, criteria and procedures that support the MAC system, proposing a modeling that can be inserted into the modern and complex system of health services.

The working posture is part of the risk factors for the development of muscle-skeletal disorders. Compared to postural problems of the trunk and upper limbs, those related to the lower limbs have been so far undervalued in the context of preventive medicine and ergonomics. The risk assessment tools for the lower limbs posture are inhomogeneous and incomplete.

[Criteria of the OCRA method in evaluating the structural assembly of aircrafts: preliminary data].

In the aircraft productive sector, the risk assessment of repetitive occupational activities through the OCRA method presents some major obstacles: - high number of different tasks (more than 20) carried out during the work shift. - definite identification of the number of technical actions per cycle. Risk assessment through the traditional OCRA method provides in this sector a index which varies according to the sampling of the occupational tasks, rather than reflecting the effective risk level.

[Role of occupational rehabilitation therapy in returning to work: experimental experience].

The experimental experience is the result of combining cultural, clinical and scientific interest in rehabilitative, occupational and forensic mnedicine and in ergonomics. It deals with the rehabilitation and return at work of patients with physical disabilities caused by occupational trauma or disease. The programme described starts with a selection by INAIL and involves with an outpatient surgery inclusion.

Electric versus hydraulic hospital beds: differences in use during basic nursing tasks.

Biomechanical, postural and ergonomic aspects during real patient-assisting tasks performed by nurses using an electric versus a hydraulic hospital bed were observed. While there were no differences in the flexed postures the nurses adopted, longer performance times were recorded when electric beds were used. Subjective effort, force exertion and lumbar shear forces exceeding safety limits proved electric beds were superior.

[The shoe industry and the musculoskeletal system].

Shoes factory workers are engaged in ripetitive tasks, often performed in constrained postures and in concomitance of force applied, which result in increased risk of musculoskeletal disorders. Risk assessment and ergonomic interventions are part of the on-site prevention program, which should pertain also to gender and age differences. Health and safety issues can be adequately faced by an active epidemiological surveillance complemented by ergonomics.

[Ergonomics and occupational therapy].

Occupational ergonomics mostly deals with risk assessment and design/redesign of the work layout, oriented to enhance the worker's safety and wellbeing and the system's efficiency. Risk assessment is the fundamental phase, conducted through international standards and guidelines, according to the different areas. Then the risk level is connected with preventive or corrective measures.
