Kindle Nelms Mrs. Ward English 23 November 2014 The Deadly Disease Have you ever heard of the deadly disease known as ALS? Do you know who discovered ALS? What is Lou Gehrig’s disease? What does ALS stand for? What are the symptoms, diagnosis, the treatments of ALS, do you know how many people get ALS, and how can you be involved help with ASL? If you do not know any of the following questions, this essay will answer all of the following. , I will tell you who discovered ALS is and describe…

These effects of stretching prominently appear to affect stretch tolerance with no changes in the viscoelastic properties of the muscle (Halbertsma & Göeken, 1994) (Magnusson, Simonsen, Aagaard, Sørensen, & Kjaer, 1996). The mechanism for increased performance following chronic stretching is believed to be related to stretch-induced hypertrophy, which is discussed more when examining the adaption mechanisms. Adaptation Mechanisms The adaptation mechanisms of acute and chronic stretching…

Whenever a shocking and seemingly senseless crime occurs, pundits are quick to connect the perpetrator’s actions to their consumption of violent entertainment. No medium, from the literary to the musical and visual, is above condemnation. At the same time, artists and creators insist that their products could not possibly influence anyone’s behaviour to such an extreme degree. Psychological researchers then have the task of finding the truth between these two polarized perspectives.…

Introduction Functional electrical stimulation (FES) or neuromuscular electrical stimulation (NMES) is an therapeutic technique by which small electrical impulses are applied to a paralyzed or spastic muscle in order to induce contraction and thereby improve its function. Traditionally, NMES refers to those stimulatory protocols directed at increasing strength and FES with function. FES can stimulate muscle contraction for exercise, bladder management, grasping, standing, and walking, among…

certain act, must feel and control what he does for that time period in which to do it or not. Libet in his subject study states that they absolutely need to move their fingers freely, at any time they feel desire while simultaneously carrying electromyography (EMG) on the fingers and electroencephalogram (EEG) on the readiness potential measurement head. On the basis of the EEG, Libet registered a signal in the brain, the so-called. The potential for readiness discovered by the German…

The effects of high-heeled shoes on knee, ankle and foot The main purpose of walking is to move the body forward, seeking to spend the least amount of energy possible. (footEducation, 2014) This form of human locomotion uses the foot to absorb and disperse the force of the body when it takes a step. Additionally, the foot propels the body forward by forming a rigid leverage toward the end of the phase of gait. (footEducation, 2014) Although this action may seem a simple task is more complex…

INTRODUCTION Can you imagine how difficult the lives could be after the amputees lost their arms or legs? Their lives will not be as easy as they had before. They cannot do many things that they used to do in their normal lives when they still have their limbs. A few hundred years ago, a hand amputee could only have a hook prosthesis with limited function and social stigma for the replacement of his hand. As the technology advances, hand amputees can now have the option for a hand transplant…

CORTICAL MAPPING USING MOTOR EVOKED POTENTIALS IN GLIOMA SURGERY INTRODUCTION The aim of glioma surgery is to get maximum resection of a tumor with minimal violation of normal brain tissue. A primary tenet of neurosurgical oncology is that survival can improve with greater tumor resection, but this principle must be tempered by the potential for functional loss after a radical removal. It has always been a challenge to achieve this ?functional? resection especially when eloquent cortex is…

swallowing (Amyotrophic Lateral Sclerosis (ALS) Fact Sheet, 2013). These symptoms can develop into more obvious weakness and atrophy causing a physician to suspect ALS. A physician will perform a series of tests including, but not limited to, electromyography, a nerve conduction study, a MRI, blood or urine workup. Based off the findings and elimination of other diseases, the physician will make the proper diagnosis. To be diagnosed with ALS, signs and symptoms of both upper and lower motor…
