Musculoskeletal Disorders, MSDs are the injuries and disorders of soft tissues from muscles, tendons, ligaments, joints, cartilage and nervous system. (US Department of Labor, 2000). Musculoskeletal Disorders also affect all the tissue included nerves and tendon sheaths and also the arms and back. Risk factors may lead to Musculoskeletal Disorders. (Smith & Verhagen, 2004). The reason of each risk factors lead to Musculoskeletal Disorders. Repetition The time of repeating the similar tasks is long, the same tissues will being loaded and the opportunity for tissue recovery will not possible. The body does not have sufficient time to recover and eventually fatigue will occur and lasty will lead to Musculoskeletal Disorders. Force Exertion Weight of an object is an indicator of force when lifting the object.The higher the weight, the greater the exertion required. Awkward Posture When joints are exposed from neutral range of postures, the muscles around the joint will be stretched or compressed. When muscle in neutral range of postures, muscle producing the greatest amount of force, but once muscle is not in neutral posture the force produce will …show more content…

Contact stress will results in inflammation of tendon and surrounding tissues, reduce blood flow and also caused early muscle fatigue. Long period of compression will cause tissue to damage and the nerves that exposed to contact stress will lead to injury. Once additional force adds, friction will created between soft tissue and hard object and irritation, which can further inhibit blood flow and nerve conduction. When working on the too high or too low surfaces with sharp edges will cause contact stress. Workers working at incorrect height or angle for long period, arms and shoulders will fatigued. Besides that, poor tool design can also result in contact stress.

    According to Neumann, a force can be considered a push or pull that can produce, arrest or modify movement and can be measured as F=ma (Neumann, 2010). Force can also be considered the load. In regards to muscle contraction force relative to the joint, the force can be the internal force produced by the muscle itself, the force of gravity or the force of the particular load/weight. Torque is a cross product between force and the distance of the force from the fulcrum and is the ability of a force to cause rotation on a lever. Torque is a measure of how much a force acting on an

    Osgood-Schlatter Disease or syndrome (OSD) is an irritation of the patellar ligament at the tibial tuberosity (Dhar). Osgood-Schlatter Disease is claimed by some to not actually be a disease (Sims). But is rather a collection of symptoms that involves the tibial tubercle epiphysis (Sims). Osgood-Schlatter Disease affects as many as 1 in 5 adolescent athletes (Diseases and Conditions: Osgood-Schlatter Disease). Some other common names for this disease are Osteochondrosis, Tibial Aponphysitis, Tibial Tubercle Apophyseal Traction Injury, Morbus Osgood- Schlatter, and Rugby Knee (Dhar). “This can cause multiple sub-acute avulsion fractures along with inflammation of the tendon, leading to excess bone growth in the tuberosity and producing a visible lump which can be very painful when hit (Dhar). Activities such as kneeling may irritate the tendon further (Dhar).”

Cardiomyopathy is a heart disease which affects the muscles of the heart. In cardiomyopathy is muscles get rigid, enlarged or thick. They also sometimes changed by scar tissues. On the other hand arrhythmia is a disorder with the rhythm or rate of heartbeat. The heart can beat fast, which is called tachycardia or it could be beating too slow, which is called bradycardia. Emery-Dreifuss muscular dystrophy is characterized by early onset of contractures and humeroperoneal distribution. Humeroperoneal refers to effects on the humerus and fibula. The genes known to be responsible for EDMD encode proteins associated with the nuclear envelope: the emerin and the lamins A and C.

    Rheumatoid arthritis is a chronic inflammatory and an autoimmune disease that occurs when the immune system mistakenly attacks the body’s tissue (Rheumatoid arthritis, 2017). This disease affects the entire body, which is called a systemic (means entire body) disease. Arthritis is derived from the word part arthr-, which means “joint,” and -itis, which means “inflammation,” so altogether it means “inflammation of the joints.” It creates inflammation that causes the tissue that lines the inside of joints (synovium) to thicken. About 1.5 million people in the U.S. are affected. It affects all races, but it affects three times as many women than men (What is Rheumatoid Arthritis, n.d.). Overtime, rheumatoid arthritis causes painful swelling that can potentially result in bone erosion or joint deformity, which leads up to physical disabilities. RA can affect more than just your joints, but can spread to body systems, skin, eyes, lungs, heart, blood vessels, e.t.c (Rheumatoid arthritis, 2017).

    Muscular dystrophy (MD) is a genetic disorder that weakens skeletal muscles, the muscles that enable the human body to move. People with muscular dystrophy have missing or incorrect information in their genes, which prevents them from making the proteins they need for healthy muscles. Due to fact that muscular dystrophy is genetic, it is not contagious or contractible from another person; a person must be born with the problem.

    There are many ways you can prevent injuries from happening before they do occur. Make sure you lift the right amount of weight to ensure that your body won’t wear down or you won’t injure yourself. Lifting more than you need to will only make your body worse. Using poor form can get you hurt quicker and easier than any other way. Make sure that you are using the correct form even if that means hiring a trainer or having a spotter. Workouts that you know can help because you will know the correct position. Workouts without machinery and weights have a lesser risk of hurting you. Cassidy says, “Years of intense workouts take a toll on your body..... Cartilage wears down and muscles, tendons, and ligaments can become less limber” (1).

    Every part of our body is a science. I never imagined the hidden science in the movements of the body. The science of kinesiology is the science of body movements. I grew up watching my grandma and the changes in her body as both of us got older, I could walk and balance properly while she lost it. I always felt bad when she was not able to get up and walk properly and as caring grandson I always gave her my hand. It was a great feeling for me to take care of her in her last days. Her difficulty in moving always pointed me to do something for her and I landed doing kinesiology- the science of human movements. I completed my high school at Cathedral High School in West Texas. I was an active member of National Honor Society as well as Spanish Honor Society. I held the treasurer position for one year in the society, which I felt proud of. I was not excellent at my academics, was just an average student struggling with the subjects of chemistry and anatomy.

(“Data & Statistics,” 2012 April 6) Muscular dystrophy is a group of genetic diseases defined by muscle fibers that are unusually susceptible to damage. There are several different types of muscular dystrophy some of which shorten the affected person’s lifespan. (“Muscular dystrophy: Types and Causes of each form,” n.d.) There is a long history of the disorder but until recently there wasn’t much knowledge of the cause. (“Muscular Dystrophy: Hope through Research,” 16 April 2014) Symptoms are obvious and can be seen as soon as a child starts walking. (“Muscular Dystrophy,” 2012 January 19) Although muscular dystrophy mostly affects boys, girls can get it too. (“Muscular Dystrophy,” 2012 January 19) There is no cure for muscular dystrophy but there are several types of therapy and most types of muscular dystrophy are still fatal.

    The most common musculoskeletal disorder and a major cause of disability in people over 65 years is osteoarthritis (OA) (Felson DT et al, 1987) (1). According to World Health Organization (WHO) report, OA of knee is more likely to become the fourth most important cause of disability in women, and the eighth most important cause in men (Murray CJL, Lopez AD, 1997)(2) . Primary prevention of knee OA has become a major health care aim and a clear understanding of the risk factors is required to design preventive strategies. Many investigations reported obesity, previous history of knee injury, sedentary life style, hand OA (Heberden’s nodes), and a familial history of the disease are major risk factors for OA of knee (Cyrus Cooper et al, 2000) (3). In spite of recent advancements the causes and pathogenesis of knee OA remains largely unknown (A Teichtahl, A Wluka, F M Cicuttini, 2003) (4) but however there is increasing research interest in the contribution of biomechanical variables on progression and management of the disease (Andriacchi TP, 1991) (5).

    The musculoskeletal system is comprised of bones, joints, cartilage, tendons, ligaments, fascia and muscles. Together these body parts work to establish a framework that is the musculoskeletal system. This framework is what gives the body its shape, form, and figure. It stabilizes the body as well as supplies the structural support. The musculoskeletal body features not only provide a framework for your body but allows your ability to create movement. These movements are monitored by the musculoskeletal components which then determine your degree of flexibility. Overall the amount of energy your body uses comes almost entirely from these musculoskeletal functions. Which makes sense because it
