“…While there were highly statistically significant difference between two groups regarding patient's functional conditions post educational guidelines. This result comes in agreement with Ngomo et al [23] & Lasanianos [24] who reported that there is considerable loss of strength at the time a muscle is placed at rest. This takes place even with relatively short times of immobility, with every day of bed rest there is to the degree that 3% loss of muscle strength, or up to 20% loss of remaining strength per week of immobilization.…”

Long immobilization periods lead to overall complication and have been associated with poor functional outcomes. The aim of this study was to evaluate the effect of educational guidelines for prevention of immobilization complications on caregivers' performance and patients' functional condition. Quazi experimental design was utilized for conducting the study. Two purposive samples of 45 immobilized patients and their caregivers from orthopedic wards in El demerdash hospital, Cairo, Egypt, were randomly divided into study and control groups. Data were collected through; Self-Administered Structured Questionnaire to assess demographic characteristics and knowledge. Observational checklist also used to assess caregivers' practice. PULSUSE profile used to assess patients' functional condition. Results: There was statistically significant improvement of caregivers' knowledge and practice regarding prevention of immobilization complications and improvement of patients' functional condition in the study group after implementation of educational guidelines when compared to the control group. Conclusion: Educational guidelines improve the caregivers' knowledge and practice regarding prevention of immobilization complication. Recommendations: It is suggested to apply these educational guidelines on the caregivers of immobilized patients and to replicate the study on a larger study sample in different settings to generalize the results.

“…How do these thresholds vary among individuals and situations? Some members of the MSD axis conduct research on neuromuscular mechanisms that may control the response to excessive exposure, focusing particularly on the biomechanical aspects of motor control (Côté et al, 2008;Fuller, Fung and Côté, 2011) and functional organization of the central nervous system (CNS) (Ngomo, Leonard and Mercier, 2012;Ngomo et al, 2011). For example, acute pain appears to stimulate complex adaptations such as increased movement variability, whereas chronic pain appears to limit variability (Côté and Hoeger Bement, 2010).…”

“…A better understanding of these physiological responses could be helpful in suggesting new workplace practices in rehabilitation (Srinivasan and Mathiassen, 2012). Moreover, changes in the CNS have been documented in patients with MSDs (Boudreau, Farina and Falla, 2010;Clark et al, 2008;Ngomo, Leonard and Mercier, 2012;Van Vliet and Heneghan, 2006). The chronicity of the deficit appears to be the main factor related to the decreased excitability, since no variation was observed in relation to pain level, functional deficit or strength deficit .…”

This paper aimed to demonstrate the contribution of the research performed by the musculoskeletal disorders (MSD) Research Axis group of the Quebec Occupational Health and Safety Research Network towards better understanding of work-related MSD (WMSD) development and prevention. Although the group targets its work to the Quebec population, its work has significant impact around the world, placing MSD axis members and knowledge and expertise created in Quebec on the international map. Results from the contribution of members are relevant, primarily in the demonstration of the implication of physical workload as well as organizational and psychosocial work-related factors in the development of WMSDs. Also, members have demonstrated that gender, sex, social class, age and ethno-cultural groups interact in various ways with WMSD determinants. Efforts are devoted towards improving understanding of the physiological responses linked with MSDs, which could also lead to new workplace practices in rehabilitation. The group emphasizes the integration of prevention procedures from the design stage to the workplace intervention. Members have proposed research-based tools for best practices at work and also an original conceptual model as a key, novel element of a theoretical conceptualization of WMSDs. Moreover, the group focuses on improving WMSD surveillance, using multiple sources of information, providing information on newly identified health risks and developing new methods of assessing risk in order to effectively prevent disability in the working population. Finally, results from research of the MSD axis group have implications for orienting legal processes, improving legal recognition of MSDs as occupational diseases, and contributing to the evolution of legal thinking. However, much remains to be done. To that end, the group plans and encourages new initiatives for further advancement. In conclusion, the originality of the work places the group in a favourable position to address the complexity underlying WMSDs, combining expertise that enriches fundamental, clinical and population-based research.

“…New ways to help the comprehension of the underlying physiopathological mechanisms in the persistence of MSDs are emerging. It has therefore been shown that some lesions caused by MSDs might be associated with, among other symptoms, a cerebral physiological signature specific to the lesion [2][3][4]. Musculoskeletal disorders (MSDs) in the neck-shoulder area have accounted an increasing number of people in the active general population.…”

“…Furthermore, recent studies have shown that MSDs are not merely local affections at the affected area, but that these lesions are coupled with a cerebral physiological signature specific to the lesion [2][3][4]. It has also been proven that different tasks require different levels of cerebral alert for an optimal performance [11].…”

Abstract-Musculoskeletal disorders (MSDs) have affected an increasing number of people in the active general population. In this perspective, we developed a measuring tool taking muscle activities in certain regions of the body, standing posture taking the center of pressure under the feet and feet positions. This tool also comprises an instrumented helmet containing an electroencephalogram (EEG) to measure brain activity, and an accelerometer reporting the movements of the head. Then, our tool comprises both non-invasive instrumented insole and safety helmet. Moreover, the same tool measures muscular activities in specific regions of the body using an electromyogram (EMG). The aim is to combine all the data in order to identify consistent patterns between brain activity, postures, movements and muscle activity, and then, understand their connection to the development of MSDs. This paper presents three situations reported to be a risk for MSDs and an analysis of the signals is presented in order to differentiate adequate or abnormal posture.
