Manual handling (bending reaching Stretching pulling lifting repetitive motions awkward postura"possible harmful effect"
Answer (1)
Repetitive or awkward manual handling without proper technique (like maintaining a straight back, using leg power, keeping loads close to the body) can lead to musculoskeletal disorders (MSDs). These are injuries affecting muscles, nerves, tendons, joints, and the spine, often causing pain and limiting movement.Harmful Effects of Improper Manual Handling PostureBendingImproper bending, like rounding your back instead of bending your knees, puts a lot of stress on your spine. This can cause back muscle strain, slipped discs (damage to the soft cushions between your spinal bones), and chronic lower back pain over time.ReachingAwkwardly reaching for things, especially overhead or far away repeatedly, can strain the muscles and tendons in your shoulders, arms, and upper back. This might lead to conditions like shoulder impingement (where tendons get pinched) or tendonitis (inflammation of tendons).StretchingWhile stretching is generally good, awkward or forceful stretching (like bouncing or pushing too far) can cause muscle tears or strains. Stretching cold muscles without warming up first also increases the risk of injury.PullingPulling heavy objects with jérky or awkward motions, or using only your back muscles, can lead to back injuries, shoulder strains, and hernias (where an organ pushes through a weak spot in muscle).LiftingLifting heavy items improperly is a major cause of injury. Using your back instead of your leg muscles, twisting while lifting, or lifting things that are too heavy can cause severe back strain, muscle tears, spinal injuries, and hernias.
