Musculoskeletal Risk Associated With Carrying Heavy Backpack Case Study

The purpose of the Boomilever Project is to build a cantilevered truss that is light-weight while still able to support 15 kilograms. With this project it serves to reinforce the cumulative concepts that have been taught throughout this semester of Engineering Statics. It has been necessary to research designs, types of wood, and types of adhesive that will create a final result that is consistent with the

Current knee brace are designed using a combination of plastic, metal and or other composite material for basic support. The additional features such as heating & cooling system (HCS), massage vibrators (MV), adding adjustor system (AS) and semi-manual strapping system (SMS) will revolutionize and modify the way we treat various knee disabilities and injury which is often overlooked globally. By combining different components together we have made a portable, multi-accessory product that can help multitudes of people to get better.

One of a gymnasts’ most common injuries is a stress fracture involving the lower back. The medical term for this is Spondylosis. The back is a very crucial part of gymnastics, it is constantly working hard and being used. Amongst gymnasts, the most common cause of a stress fracture is overuse. However, they can also occur due to an awkward fall or a fall from a height. Almost everything in gymnastics calls for a combination of great speed and power which puts any gymnast at high risk of falling or landing wrong. Whether it’s a fall or an awkward landing, the pressure is being applied to the spine and joints, increasing the chances of injury. Back injuries in adolescent athletes stem from repetitive stressful body movements, like bending and twisting that can cause trauma to the spinal column. The

Lifting and moving loads manually is the biggest cause of injury, so it is important to

NASA has always had the best equipment available to them when training their astronauts to live in a reduced gravity environment. Now their equipment is being used to help treat and prevent many different sports injuries. The Alter-G anti-gravity treadmill is being implemented in many rehabilitation centers for use as sports injury therapy.

The goal of this project is to work towards answering the question of whether or not football helmets promote neck injuries. In order to gather data, a U of R team made a machine that rapidly changes speed while translating from side to side to stimulate a rotational acceleration and velocity about the head and neck due to an angular displacement. The purpose of this machine is to simulate an unexpected and sudden change in motion of the head in order to analyse the resulting motion. The data collected was the rotational position of the head, the linear position of the cart, and the linear position of a point on the body. All measurements were made with and without a helmet. In order to answer the main question, there had to be a further understanding of how the mechanics of the head and neck change with the addition of a helmet. To achieve this, MATLAB was used to compute the resulting velocities and accelerations, the reaction forces at the neck, and the moment about the base of the neck. From these calculations, it is possible to make observations about how the addition of a helmet affects the dynamics of the head and neck.

Two of the most common symptoms chiropractors treat are neck and back pain. What is surprising is the patients complaining of these painful symptoms seem to be getting younger due to the wearing of backpacks. When heading out to school it is customary to stuff the backpack full of notebooks, heavy textbooks, food, clothes and other supplies weighing it down. According to the American Chiropractor Association (ACA), “In a new and disturbing trend, young children are suffering from back pain much earlier than previous generations, and the use of overweight backpacks is a contributing factor.”

Adults aren’t the only ones suffering from back pain in Frisco, TX. It’s back-to-school season and your child’s backpack is a likely culprit for acute and chronic back pain, in addition to related injuries. Kids who carry a backpack to school are more likely to complain of pain in their backs, necks and shoulders. This is due to too-heavy backpacks that are often worn and lifted incorrectly. When a backpack is too heavy for a child to support, they will be forced to bend forward, causing pain and potential injury. Life Changing Chiropractic can help you identify common backpack problems and pick an item that will keep your child healthy and comfortable.

When absorbing ground reaction forces during physical activity, rather than using the muscular prime movers of the lower extremity, females act on the use of bony configuration and articular cartilage and ligaments to absorb these forces (4). Newton’s third law states that for every action, there is an equal and opposite reaction. In any action of sports whether a soccer player makes a cut on the field, or a basketball player lands from grabbing a rebound, the reaction force is actually greater than an

Stress fractures account for approximately twenty percent of athletic injuries, with eighty percent of stress fractures occurring in the lower leg. Stress fractures in the lower extremity are common injuries among individuals who participate in endurance, high load-bearing activities (2). The incidence of these injuries has risen due to earlier and longer participation in sports (3). Stress fractures occur when repetitive mechanical load exceeds the biological capacity of bone, causing micro-damage (1). This rate exceeds the rate at which bone can repair itself, requiring recognition and management of risk factors (2). The initial stage of bone failure is typically called a stress reaction. If the repetitive loading continues, the stress reaction can form into a true stress fracture (3).

The present weighted running vests are a wonder of current innovation. The light materials utilized take into account extending and a cozy fit to your body. The office to evacuate and include weights is a fundamental piece of the vest’s ease of use, and the lashing framework is
