Musculoskeletal disorders (MSDs) can affect many parts of the body, primarily involving the muscles, bones, joints, tendons, ligaments, cartilage, and spinal disks. The affected body parts commonly include:

• The lower back, which is often impacted by poor lifting or moving tasks.
• The hips, legs, knees, ankles, and feet, including joint and soft tissue problems in the lower limbs.
• The upper limbs such as shoulders, forearms, wrists, hands, fingers, and the neck, which may be affected by repetitive strain injuries or conditions like carpal tunnel syndrome and tendonitis.
• Joints throughout the body, with conditions like osteoarthritis, rheumatoid arthritis, gout, and psoriatic arthritis causing pain, swelling, stiffness, and reduced mobility.
• Muscles, bones, and adjacent connective tissues, including issues like fractures, sprains, strains, and chronic conditions affecting mobility and dexterity.
• Some musculoskeletal disorders can also involve nerves and blood vessels related to the musculoskeletal system.

Overall, MSDs affect both upper and lower back, neck, shoulders, extremities (arms, legs, feet, hands), and multiple body areas including joints, muscles, bones, and connective tissues.
