Musculoskeletal Disorders – I

    “Musculoskeletal disorders are sprain (i.e. wrist or ankle twist or bending), strain and overuse problems which affect your body’s structure i.e. muscles, ligaments, joints, tendons and nerves that are support limbs, neck and back”. 

• Tendinitis
• Rheumatoid arthritis
• Backache
• Tenosynovitis
• Osteoarthritis
• Fibromyalgia
• Slipped discs
• Bone fractures

    Simple methods of pain relief will usually alleviate the pain. However, if pain or discomfort persists, it’s highly advisable to seek professional medical advice. If you don’t focus on your workers symptoms they may begin to figure out new ways of doing their job or modifying their tools. This generally occurs because a cleaner is attempting to reduce pain and discomfort in a particular area of their body. Unfortunately, doing this puts increased strain on the rest of their joints, ligaments and nerves.

1. Back Injuries & Back Pain: Irritations or problems with spinal muscles, nerves, bones, discs or tendons in the lumbar spine causes lower back pain that radiates / transfer to other parts of body. Lower back pain is extremely common for workers who involve in repetitive job patterns which increase due to poor postures while doing a job, standing or sitting for a long period of time, work related stress and strain, etc. 
   
   
2. Work-Related Upper Limb disorders (WRULD): WRULDs are work-related musculoskeletal disorders that mainly affect the neck, shoulders, forearms, elbows, wrists, hands and fingers. WRULD are mostly referred as ‘sprains’ or ‘strains’ and repetitive strain injuries.
3. Other Chronic Soft-Tissue Injuries: Sudden uncontrolled and unexpected movements due to awkward positions at work mostly results in soft-tissue injuries (STI). Overuse of muscles and tendons also results in STI. Chronic soft-tissue injuries are more painful and may leave the injured with frustration and stress.
