Vestibulo-Ocular Sickness Essay

1. describes how a range of factors have a negative and positive impact on individuals with sensory loss.

The research study performed in the article involved a number of professional piano players in Scandinavia performing a favored piece numerous times in front of the researchers. After each of the five times that the piece was played, researchers would monitor various physiological aspects of the performers (including heart rate, muscle tone fluctuation, blood pressure and thoracic respiration) in order to analyze the physical effects of reaching a state of flow. It is noteworthy to mention that not all of the players reached such a state in each of the five times they played a particular piece, which attests to the inconsistent and elusive qualities of flow.

Eye Vision Inc, a long-standing medical device manufacturer, has signed a contract to sell Holland Hospital the Clear View Laser and a two-year separately priced maintenance plan for $1 million and $0.2 million respectively. On a when-and-if available bais, Eye Vision Inc. will provide software updats that is embedded with the Laser to maintainance purchasor. The software has never been sold without Laser for its functional necessity. In this memo, as explained below, we conclude that:

The Polyvagal theory developed by Stephen Porges and introduced in 1994 provides new insight into the functioning of the autonomic nervous system. The theory provides a clear understanding of the nervous system which plays a huge role for dancers as it can influence mental and physical performance, as well as keeping pain-free.

Recording time constants allows the clinician to evaluate the peripheral vestibular response in combination with the velocity step (approximately 6 seconds), as well as the response of the velocity storage mechanism. The time constant is measured by following the same line as the phase angle from sinusoidal acceleration. The normal range is 10-30 seconds. Gain measures for step testing include gains of 0.4 or above as normal and percentage difference of less than 30 % as normal (Goulson, McPherson, Shepard, 2016). High speed step testing is typically used to localize right or left hypofunction. If there is an abnormal percentage difference for the slow speed, this is suggestive of uncompensated asymmetrical peripheral performance. Abnormal fast phase percentage in the same direction is also suggested for uncompensated hypofunction. If the slow speed test returns to normal but the high speed test is abnormal, the likely finding would be hypofunction on the side with the weaker response that has been compensated for centrally (Goulson, McPherson, Shepard,

During the Apollo space missions, as well as later missions, American astronauts encountered a new phenomenon, space motion sickness. American scientists wanted to know what was causing this sickness, and looked to Russian research for answers, as Russian cosmonauts had encountered this phenomenon before. Historically, Russian scientists attributed the sickness to fluid shift, a process where decreased gravity allows fluids in the body to move headward. This can cause imbalances in hormones or neurotransmitters. It can also increase intracranial pressure, including in the inner ear, causing difficulties in the vestibular area of the ear. A more recent theory attributes the problem to sensory conflict. Through research and experimentation, scientists

Elevated blood pressure, blood pressures at home, however, have been excellent. She has had side effects on both atenolol as well as losartan. Given that her blood pressures are so well controlled at home and it is good today, we will hold on starting her on any blood pressure medications. She will continue to monitor her blood pressure.

The Alfred Hitchcock film; Vertigo is a narrative film that is a perfect example of a Hollywood Classical Film. I will be examining the following characteristics of the film Vertigo: 1)individual characters who act as casual agents, the main characters in Vertigo, 2)desire to reach to goals, 3)conflicts, 4)appointments, 5)deadlines, 6)James Stewart’s focus shifts and 7)Kim Novak’s characters drives the action in the film. Most of the film is viewed in the 3rd person, except for the reaction shots (point of view shot) which are seen through the eyes of the main character.(1st person) The film has a strong closure and uses continuity editing(180 degree rule). The stylistic (technical) film form of Vertigo makes the film much more

MS is a disease that involves that demyelination of the neuromuscular system (cite). This autoimmune disease is characterized by extreme fatigue and limited mobility; this in turn affects his or her balance. In this study done by Dr. Jeffrey Herbert and company, thirty-eight subjects underwent a fourteen-week single-blinded, randomized controlled trial aimed to combat vestibular deficiency using a VR program and exercise protocol for endurance training. The subjects were then randomly allocated into three separate groups: experimental intervention (12), exercise intervention (13), and control (13). Additionally, the following weeks were organized into three phases: 1. Measuring the patient’s baselines (Week 1-4) 2. Performing the interventions in a human performance laboratory (Week 5-10) and 3. Measuring the outcomes (Week 11-14). The experimental group worked on a VR program that has clinical and literature based evidence that includes upright postural control and eye movement exercises (cite). A firm surface, foam cushion, and tiltboard were all used to change the base of support (BOS) during upright postural control, in addition, the investigators also challenged the subjects by closing/opening their eyes, tossing objects for them to catch, and changing their feet placement (shoulder width, heels together, partial heel to toe, and tandem). The eye movement exercises for the protocol

Traumatic Optic Neuropathy, T.O.N, is the direct or indirect injury to the optic nerve or optic canal secondary to trauma. Patients who present with T.O.N may have partial or complete vision loss. Due to little understanding, there is no prevention and no cure for T.O.N; or laboratory models to study this condition. Most common causes are motor vehicle accidents, falls, bike accidents, and assault. Though observation is the main treatment option, systemic corticosteroids and surgical optic nerve decompression is available .

Vision defines the fundamental way we perceive and respond to stimuli. While static visual acuity for identifying a stationary target is one of the basic visual functions, there are many other important visual functions. In particular, the visual function designed to identify moving targets has been examined by a considerable number of researchers. The dynamic visual acuity (DVA) test, in which scores reflect the difference in visual acuity between stationary and head rotation, measures the individual’s ability to maintain gaze during head rotation. The term “dynamic visual acuity” (DVA) refers to an individual's ability to see clearly during head movement and is a behavioral measure of angular vestibulo-ocular reflex (aVOR) function. The Dynamic

In this paper, I introduce a report about the effects on kinematics and electromyographic activity of the scapular waist in young competitive swimmers before and after performing a maximum effort test simulating the sporting gesture. This is significant because of the high number of injuries that swimming athletes present in the shoulder joint. Understanding how the biomechanics of the scapular waist joint behaves

The final element that was tested against the baseline reflex was the influence of fatigue on the strength of the reflex response. This was achieved by having the subject run up and down three levels of stairs three times in the Frost building stairwell of Holyoke Community College. The subject immediately came back to the original sitting position on the edge of the lab bench with legs dangling freely, and the patellar tendon was tapped once more.

1.1 There are many different facts that can have an impact on people with sensory loss. Communication and awarness can play big roles in the impact. They may find it difficult to feed themselves,dressing and mobility. Hobbies and interests can have a negative impact on their lives. They may also feel scared and alone due to this. There can be positive factors that can help out the person such as,increased help,aids for support and a good support team could give them a brighter outlook on life. Organisations may help the deaf and blind with many different aspects of their life to support or to helping them get the right kind of support.
