  • Muscle Tissue Analysis

    Introduction: The use of electromyography (EMG) to monitor muscle tissue from surface skin provides important information about the components of electrical activity—namely motor unit (MU) activation—during a muscle contraction (Cashaback, Cluff & Potvin, 2013). Observing electrical activity of a muscle with EMG is a user friendly and non-invasive tool researchers use when investigating muscle physiology (Camata et al., 2009). EMG is commonly used to correlate EMG signal with fatigue by identifying the EMG-force relationship (Ertl, Kruse & Tilp, 2016). Additionally, EMG is used as a means of quantifying the activation of muscle tissue through the observation of fluctuations in EMG amplitude (Ertl et al.). There are different protocols for…

  • Electro Diagnostic Testing Essay

    Nerves and muscles in the body send electrical signals throughout the body- sending and receiving messages to the brain. Electro diagnostic testing helps the doctor to get a better understanding of how those electrical signals are functioning in the body. There are two types of electro diagnostic testing; Electromyography, more commonly known as an EMG, and Nerve Conduction Studies, or NCS. An EMG allows the doctor to monitor and understand the electrical action that takes place within the body.…

  • Duchenne Muscular Dystrophy

    160116 Duchenne Muscular Dystrophy “Muscular dystrophy (MD) is a genetic disease characterized by progressive weakness and degeneration of the skeletal or voluntary muscles which control movement” (Muscular dystrophy, 2013). Muscular dystrophy is classified into nine major types that each affect specific muscle groups, certain age groups and are identified by different signals. Duchenne muscular dystrophy most commonly affects males and is targeted at younger children (Facts about Muscular…

  • Physiological Effect Of Duchenne Muscular Dystrophy

    Introduction Duchenne muscular dystrophy, or DMD, is the most common and severe type of muscular dystrophy, caused by a genetic disorder that leads to progressive muscle weakness and degradation (Marieb & Hoehn, 2015). DMD is a recessive sex-linked disease and is often inherited through the mother. Because this condition is enacted by a mutation of the X chromosome, it is expressed almost exclusively in males, with one in every 3,600 males affected worldwide (Marieb & Hoehn, 2015). The DNA…

  • Effects Of Adding Biofeedback Training To Active Exercises

    arthroplasty (This is a procedure carried out surgically and it is designed to alleviate knee pain and improve the functional activity of patients with chronic knee osteoarthritis) This study was carried out amongst forty five patients ages from fifty eight to sixty seven years. In this situation an electromyography (EMG) biofeedback training is used. After total knee arthroplasty some patient shows impairments in muscle strength, which always lead to increase risk in falling and ending up in…

  • Informative Essay: What Is Bell's Palsy?

    It could occur to people of all age but more common among between the ages of 15 to 60 years. Patients diagnosed with diabetes, hypertension. Upper respiratory and pregnant women are at a high risk of having Bell’s palsy disease and this disease could be controlled if individual’s immune system is taken care of properly Bell’s palsy could be diagnose by a Physician through physical examination to check for the facial muscles weakness, Magnetic Resonance Imaging (MRI) or Computed Tomography (CT)…

  • Videogame Effects On Adolescents Essay

    adolescents focused on how violent videogames caused increased aggression and desensitized children towards disturbing or violent media. Other researchers point out accusations of bias in the original studies, mainly because recent research does not support the original findings. The results produced from newer studies conducted in a similar fashion as the previous research show inconsistent finding which lead researchers to question the real connection between violence in games and aggression…

  • Alpha Waves Reflective Essay

    However, when the subject shut her eyes and started doing math in her head, the alpha waves had a slightly lower amplitude. Then when the subject stopped doing math, but remained with her eyes closed the amplitude increased. By applying any thought, or having eyes opened caused a decrease in amplitude. However, when the subject sat with eyes closed, and the brain providing no thought amplitude increased. These results remained true when the subject listened to music. Upbeat music caused an…

  • Sleep-Wake Regulation Of Sleep Essay

    Sleeping is a natural part of our daily life. It is a behavior that is displayed every day and is necessary for us to function. To be able to rest efficiently an animal, be it a human or another mammal, needs to fall asleep in a matter of seconds or minutes; but since a sleeping animals are more vulnerable to predation, it also needs to wake easily in case of threat. Those requirements show how well regulated the sleep-wake regulation has to be. Historically, sleep studies have been done by a…

  • Bauby's The Diving Bell And The Butterfly

    Although muscular function is diminished, cognitive function is unaffected. Currently, there are three types of LIS as described by Bauer; complete or total (quadriplegia and anarthria, no eye movement), Classic (vertical eye movement and blinking), and Incomplete (some voluntary movements are recovered and more eye movements available). Both males and females are equally at risk for Locked-in Syndrome. It can also affect people of any age but mostly adults who are more at risk for strokes and…
