Manual Materials Handling and Work-Related Musculoskeletal Disorders

Question 1

The lumbosacral joint, called L5-S1, represents a part of the spine. L5-S1 is connected at a point that lumbar 5 culminates and the sacral 1 spine begins. The L5-S1 is related on the premise that they form a joint that connects lumbar and sacral bones. Specifically, the L5 controls nerves that are essential in lifting the toe and foot. The muscles holding the toe and foot are weakened if the lumbar bone is impinged. The S1 equally controls the movement of the foot. As such, impingement of the S1 bones holding nerves weakens the gastronemius in the calf back further inhibiting foot thrusting. The herniated disc or bulging disc represents a section of the disc nucleus thrusting out of the annulus all through to the spinal canal. The disc often bulges during the initial stages of degeneration. It is imperative to note that the spinal canal has limited space to accommodate the spinal nerve and the bulging disc. This means that as the disc bulge, the spinal nerves are pressed resulting in severe pain. Nevertheless, there are strategies that can be employed to prevent injuries resulting from pressed spinal nerves. These strategies include weight management, engaging in constant exercises to enhance blood flow, and avoiding lifting heavy loads that may strain the spine.

Question 2

Workers encounter injuries resulting from inappropriate bending while picking objects. It is imperative to train workers about the best techniques of picking objects to prevent recurrent back injuries. Education, empowerment, enlightenment, and encouragement (Es) principle is widely used to help people learn more about picking objects in ways that does not strain the spine. Foremost, education is a core principle of disseminating knowledge relating to proper picking of objects and bending. Under this principle, workers are taught about the need to equally distribute weight across the body to protect bones, nerves, tendons, and muscles. In addition, enlightenment focuses on encouraging workers to embrace changes aimed at achieving better health and wellness. The changes that the workers embrace relate to the significance of protecting the body from unnecessary bending when picking objects. Consequently, encouragement represents the utmost efforts that organizations can utilize to promote proper bending and prevent back injuries. The workers are persuaded to desist from bending carelessly when picking objects to enjoy a healthy life. The words employed under the encouragement principle highlight the significance of proper bending to relieve them up from unnecessary back injuries and pains.

Question 3

The principal cause of back injuries in humans is poor lifting techniques. As such, people are encouraged to incorporate appropriate lifting techniques to protect their backs from unnecessary injuries. However, some people experience challenges lifting objects like a box from the top of as table.  In this case, the initial step of lifting a box is examining and deciding on the lifting path from the table to the floor. In this step, evaluation of activities to be engaged in during the lifting such as midway rest is noted. The second step embodies balancing and stabilizing the load to ensure the load is manageable. This step is particularly important because it prevents instances that a person is prompted to carry an unnecessary heavy load.  The third step involves the movement of the load closer to the body while also securing the box using the palms. It is important to use the leg’s strength to control the lifting in a seamless manner during the third step. In addition, the stomach muscles must be tightened and the head and shoulder maintained in the upright posture. Consequently, the feet and not the waist line are allowed to move freely. Finally, I recommend that one carrying the box moves towards the exact point the load should placed. Slowly the box is placed on the floor with the use of hands.
