Understanding the Risk of Improper Manual Lifting

Common Injuries from Improper Lifting

Improper lifting can cause a range of musculoskeletal injuries, including:

Strains and sprains: These are the most common types of injuries associated with improper lifting. Strains occur when a muscle or tendon is stretched too far or torn, while sprains occur when a ligament is stretched or torn. Strains and sprains can cause pain, swelling, and limited mobility.
Hernias: A hernia occurs when an organ or tissue protrudes through a weak spot in the surrounding muscle or connective tissue. Lifting heavy objects using improper technique can increase the risk of developing a hernia, particularly in the abdominal area.
Disc injuries: The spinal discs are small, fluid-filled cushions that sit between the vertebrae in the spine. Lifting heavy objects with improper technique can put excessive pressure on the spinal discs, causing them to bulge, rupture, or herniate. These injuries can cause pain, numbness, and weakness in the back, legs, or arms.
Lower back pain: Improper lifting can cause acute or chronic lower back pain. Acute back pain can result from sudden trauma or strain, while chronic back pain can develop over time due to repeated improper lifting. Back pain can make it difficult to perform daily activities and can significantly reduce quality of life.
Shoulder injuries: Lifting heavy objects with improper technique can cause shoulder injuries such as rotator cuff tears, dislocated shoulders, and impingement syndrome. These injuries can cause pain, weakness, and limited range of motion in the shoulder joint.
Neck injuries: Improper lifting can cause neck injuries such as strains, sprains, and herniated discs. These injuries can cause pain, stiffness, and limited range of motion in the neck and shoulders.

It's important to note that these injuries can range in severity from mild to severe, and some may require medical treatment or even surgery to correct. By following proper lifting techniques, workers can significantly reduce their risk of developing these types of injuries.

Long Term Effects

Repeated improper lifting can have long-term effects on a person's musculoskeletal system, potentially leading to chronic health problems such as:

Chronic back pain: Repeated improper lifting can put excessive strain on the muscles and ligaments of the back, leading to chronic pain. Chronic back pain can significantly impact a person's quality of life, making it difficult to perform daily activities and causing emotional stress.
Degenerative disc disease: Improper lifting can cause wear and tear on the spinal discs, leading to degenerative disc disease. This condition involves the breakdown of the spinal discs over time, causing them to lose height and elasticity. Symptoms can include back pain, numbness, and weakness in the legs.
Osteoarthritis: Improper lifting can cause joint damage and inflammation, potentially leading to osteoarthritis. This condition involves the breakdown of the cartilage in the joints, leading to pain, stiffness, and limited mobility.
Herniated discs: Repeated improper lifting can increase the risk of developing herniated discs, which can cause pain, numbness, and weakness in the legs or arms. Herniated discs can be a chronic condition, requiring ongoing medical treatment and potentially limiting a person's ability to perform certain activities.
Spinal stenosis: Improper lifting can contribute to the development of spinal stenosis, a condition in which the spinal canal narrows, putting pressure on the nerves in the spine. This can cause pain, weakness, and numbness in the legs and feet.
Spondylolisthesis: Repeated improper lifting can contribute to the development of spondylolisthesis, a condition in which a vertebra slips out of place and puts pressure on the nerves in the spine. This can cause pain, numbness, and weakness in the legs, as well as a loss of bladder or bowel control in severe cases.

Overall, repeated improper lifting can have serious long-term effects on a person's musculoskeletal health, potentially leading to chronic pain, disability, and a reduced quality of life. By following proper lifting techniques and taking steps to protect their musculoskeletal health, workers can help to prevent these long-term effects.
