About

Work-related musculoskeletal disorders (WMSD) are a major public health problem both in France and internationally. Our clinical research project focuses on WMSD of the shoulder (WMSD-S), which account for 32% and 23% of these disorders in France and Europe, respectively. In order to prevent WMSD-S, the assessment and rehabilitation of workers' physical and functional capacities (PFC) (e.g. joint amplitude) may complement current interventions (e.g. ergonomics) in a novel manner. As a result, the objectives of this project would be to conduct a cohort study assessing the PFC of caregivers with WMSD-S compared to those of healthy subjects and a randomised, controlled, single-blind, multicentre clinical study assessing the relevance of a rehabilitation program for caregivers with WMSD-S working in a hospital setting. This project would foster the promotion of evidence-based physiotherapy and lead to the development of a interdisciplinary research team dedicated to rehabilitation.

Full description

Work-related musculoskeletal disorders (WMSD) are "a set of peri-articular conditions that can affect various structures of the upper limbs, lower limbs and back: tendons, muscles, joints, nerves and the vascular system"(1). WMSD are a major public health problem both in France and internationally. Indeed, these disorders represent 85% of occupational diseases in France (2). Our research project focuses on WMSD-S representing 32% and 23% of these disorders in France (3) and Europe (4), respectively. These shoulder disorders lead to a decrease in the quality of life of workers (2) but also have direct (e.g. 50K € for shoulder tendinitis [ST]) and indirect (e.g. between 100K and 350K € for ST) costs (5).

To prevent WMSD-S, current recommendations encourage regular assessments and interventions at the workers workstation (e.g. biomechanical constraints, ergonomics, etc.) (6,7), their organisation (e. g. "job rotation"...) (8) and psycho-social factors (e. g. stress...) (9) related to work. WMSD-S), which account for 32% and 23% of these disorders in France and Europe, respectively. In order to prevent WMSD-S, the assessment and rehabilitation of workers' physical and functional capacities (PFC) (e.g. joint amplitude) may complement current interventions (e.g. ergonomics) in a novel manner.

It is believed that the assessment of PFC in workers suffering from WMSD-S is essential to better understand the origin of these disorders, and therefore to optimise their care (10) . To our knowledge, no clinical studies have analysed the interest of a protocol for the assessment of WMSD-S in caregivers. From this observation, the first part of this project would consist of a cohort study assessing the PFC of caregivers with WMSD-S, compared to those of healthy subjects matched in age and gender. This study would improve the understanding of the worker's physical and functional impairments; a fundamental aspect for the individualised person-focused interventions (i.e. rehabilitation), in addition to those carried out at the workstation level (i.e. ergonomics).

Inclusion criteria

For caregivers with shoulder pain, the inclusion criteria would be: aged between 18 and 65; being a caregiver in a hospital department and having WMSD-S, objectified by shoulder pain.
For healthy subjects , the inclusion criteria would be : aged between 18 and 65 and no shoulder pain (0/10 on visual analogic scale) in the last 3 months, both at rest and during activity.

Exclusion criteria

For caregivers with shoulder pain, The exclusion criterion would be any traumatic event not related to the professional activity that could impair the functionality of the upper limbs.
For healthy subject, the exclusion criterion would be any injury to shoulder muscles or tendons.
For both groups, the exclusion criteria would include smoking, being pregnant, and engaging in traumatic physical activity of the shoulder and any systemic disease or neurological injury.
