What causes lumbosacral strain?

Answered by Robert Dupre

Lumbosacral strain, also known as lower back strain, can occur due to a variety of factors. One common cause is overexertion or sudden movements that push the muscles and tendons in the lower back beyond their usual range of motion.

For example, twisting your body abruptly or bending over improperly can place excessive stress on the muscles and tendons in your lower back, leading to a strain. This can happen during everyday activities like lifting a heavy object without using the correct technique or reaching for something in an awkward position.

Sports activities can also contribute to lumbosacral strain if proper form and technique are not followed. In sports that involve repetitive movements or excessive force on the lower back, such as weightlifting or golf, the risk of strain increases.

I personally experienced lumbosacral strain when I was attempting to lift a heavy box without bending my knees and using my leg muscles. Instead, I relied solely on my back muscles, which resulted in a sudden sharp pain in my lower back. It took several weeks of rest, physical therapy, and proper lifting techniques to recover from that injury.

In addition to poor technique, other factors can also increase the likelihood of lumbosacral strain. These include weak core muscles, poor posture, obesity, and a sedentary lifestyle. When the muscles in the core, which includes the abdominal and back muscles, are weak, they are less able to support the spine and distribute the load properly, making the lower back more susceptible to strain.

Furthermore, maintaining poor posture, such as slouching or sitting for prolonged periods with a rounded back, can place additional stress on the lower back and increase the risk of strain. Being overweight or obese can also contribute to strain as the excess weight puts extra pressure on the spine and surrounding structures.

Lastly, a sedentary lifestyle can weaken the muscles in the lower back and make them more prone to injury. Lack of regular exercise and movement can lead to muscle imbalances, making it easier to strain the lower back when sudden or excessive movements occur.

To prevent lumbosacral strain, it is important to practice proper lifting techniques, maintain good posture, and engage in regular exercise to strengthen the core muscles. Stretching before physical activity can also help prepare the muscles for movement and reduce the risk of strain.

Lumbosacral strain can occur when the muscles and tendons in the lower back are pushed beyond their usual range of motion. This can happen due to sudden or forceful movements, improper lifting techniques, poor posture, weak core muscles, obesity, and a sedentary lifestyle. Taking preventive measures and being mindful of how we move and lift can help reduce the risk of lumbosacral strain and maintain a healthy back.
