Syndrome du canal carpienLe syndrome du canal carpien (en anglais, carpal tunnel syndrome ou CTS) est un ensemble de signes fonctionnels et physiques lié à la souffrance du nerf médian au niveau du poignet par sa compression (par élévation de la pression au sein du canal carpien). Ce syndrome peut résulter de nombreuses maladies, affections, accidents et sollicitation permanente du poignet comme les secteurs professionnels du nettoyage, de la restauration, de la manutention.
Trouble musculosquelettiquevignette|307x307px Le terme générique de « trouble musculosquelettique » (TMS), ou de « lésion attribuable au travail répétitif » (LATR), au Québec, regroupe de nombreuses pathologies des tissus mous (muscles, tendons, nerfs). C'est la maladie professionnelle la plus courante dans les pays développés en 2012. L'expression est plus couramment utilisée au pluriel. En France, la plupart des TMS sont reconnus dans le tableau 57 des maladies professionnelles du régime général de la sécurité sociale et dans le tableau 39 du régime agricole.
Ergonomic keyboardAn ergonomic keyboard is a computer keyboard designed with ergonomic considerations to minimize muscle strain, fatigue, and other problems. The common QWERTY keyboard layout is credited to the mechanical typewriter designed by C. Latham Sholes and patented in 1878; research indicates the layout may have been influenced by telegraph operators. The offset in the columns between rows was designed to accommodate the physical links between each key and the internal mechanisms of the typewriter; as typing duties transitioned to electric (motorized) typewriters and then computers, the layout was retained to ease the transition for users that had already been trained to type.
ErgonomieL’ergonomie est « l'étude scientifique de la relation entre l'humain et ses moyens, méthodes et milieux de travail » et l'application de ces connaissances à la conception de systèmes « qui puissent être utilisés avec le maximum de confort, de sécurité et d'efficacité par le plus grand nombre ». Le terme « ergonomie » vient du grec ancien / érgon (« travail ») et / nόmos (« loi »).
Ergonomic hazardErgonomic hazards are physical conditions that may pose a risk of injury to the musculoskeletal system due to poor ergonomics. These hazards include awkward or static postures, high forces, repetitive motion, or short intervals between activities. The risk of injury is often magnified when multiple factors are present. Environmental, operational, or design factors can all negatively impact a worker or user; examples include whole-body or hand/arm vibration, poor lighting, or poorly designed tools, equipment, or workstations.
List of repetitive strain injury softwareRepetitive strain injuries (RSI) are injuries to the body's muscles, joints, tendons, ligaments, bones, or nerves caused by repetitive movements. Such injuries are more likely if the movements required force or were accompanied by vibrations, compression, or the maintenance of sustained or awkward positions. Prolonged use of computer equipment can result in upper limb disorders, notably in the wrist or the back. RSIs are a subset of musculoskeletal disorders.
TendinopathyTendinopathy is a type of tendon disorder that results in pain, swelling, and impaired function. The pain is typically worse with movement. It most commonly occurs around the shoulder (rotator cuff tendinitis, biceps tendinitis), elbow (tennis elbow, golfer's elbow), wrist, hip, knee (jumper's knee, popliteus tendinopathy), or ankle (Achilles tendinitis). Causes may include an injury or repetitive activities. Less common causes include infection, arthritis, gout, thyroid disease, diabetes and the use of quinolone antibiotic medicines.
