PROGRAM OUTLINEBack SystemIn order to prevent back injuries, an understanding of how the back functions is important. We will review the following aspects of the back system:- Anatomy - Causes of Back Pain- Strains and Sprains- Prevention of Back Injuries- Workstation Ergonomics- Body MechanicsAnatomy- The spine is a complex structure and vulnerable to injury, misuse and natural aging.- The spine must be mobile so you can move; it must be stable so you can remain upright.- The ideal alignment of the spine is when the joints in the spine are lined up so the back can twist and bend with little friction between bones and vertebrae.- Discs are described as soft hockey pucks with fluid inside or like a jelly donut.- When lifting, keep the spine in its natural curves by keeping your back straight.- Bending your back pinches the discs and exerts pressure on one side of the discs.- Two ligaments run the length of the spine and help hold the vertebrae together.- Ligaments expand as you stretch your body.- Small muscles in the back span two or three vertebrae that allows the body to be straight and lift objects.- Abdominal muscles in front of the body allow us to bend forward and support the back.Causes of Back Pain- The back deteriorates from repeated wear and tear over the years.- Stress on the back comes from excessive forward bending or heavy lifting, sitting and standing on the job.- Poor posture and sports involving impact or twisting can put stress on the back.Strains and Sprains- Strains and sprains can occur when bending too far too often, lifting a heavy load or twisting suddenly.- The small, delicate ligaments attached to your spine are vulnerable to tears. - It has been determined that there is a 10:1 ratio of back pressure to the weight of the load you are lifting.- Load should be against your body when lifting, keep your back at its natural curve when bending and lifting.- Discs are spread evenly across the surface of the vertebra.- Compressing your back when lifting, the discs absorb the load evenly across the surface of the disc.Prevention of Back Injuries- There isn't a doctor, training program or medication that can prevent back injuries. Only you can prevent back injuries.Workstation Ergonomics- Ergonomics means fitting the workstation to the employee's comfort.- Keep your keyboard directly in front of you when using a computer.- The screen must be kept at a comfortable distance. - The top of the computer screen should be at eye level so the neck is in a neutral posture.- Wrists must remain in a neutral position. Keep wrists straight.- Office chairs should have adequate heights, adjustable armrests, seat and back.- The chair height should be so your knees are level with or just slightly below the level of your hips.- Armrests keep your arms comfortable while keeping your elbows bent at a 90-degree angle.- Robotics for tedious, repetitive tasks is sometimes used.- Vacuum lifting equipment is used for repetitive loads.- Forklifts, pallet jacks, carts are also used for lifting tasks.Body Mechanics- Body mechanics is keeping your body in a proper position that keeps the back in its natural curve with all body parts working in a safe manner.- Stretching, twisting and bending your back are natural body movements, but you must resist twisting to protect your back system.- According to the medical community, smoking leads to drying and stiffness of discs making them more susceptible to injury.- Always push objects such as carts and materials on rollers - push, don't pull.- Function training is going through the work area, identifying potential hazards and developing policies and procedures to reduce lifting hazards.
