Cognitive-Motor Task Conditions
For this part of the study, dynamic posturography will be combined with the cognitive testing. Just prior to beginning a dynamic posturography trial, participants will be provided with an alpha-numeric sequence. Following the 20 second posturography trial, the participants will be instructed to indicate the sequence in reverse order. Performance on balance and cognitive task will be determined as discussed earlier. In addition, the cognitive-motor task cost on equilibrium score will be determined as follows:
Cognitive-motor task cost on equilibrium score=
((Equilibrium score from cognitive-motor task condition)-(Equilibrium score from dynamic posturography alone))/(Equilibrium score from dynamic posturography …show more content…
The independent variables will be group (survivors and controls) and task condition (dynamic posturography only and dynamic posturography with added cognitive load). A separate analysis will be performed for each dependent variable; equilibrium score, vision ratio, somatosensory ratio and vestibular ratio. To adjust for the multiple comparisons alpha level will be set on .001.
Hypothesis #3
An independent sample t test will be used also to compare cognitive motor task cost on equilibrium score between survivors and controls. The independent variable will be group (survivors and controls) and the dependent variable will be cognitive-motor task cost on equilibrium score.
Hypothesis #4
Multivariate Analysis of Variance (MANOVA) will be used to examine if there is a difference in cognitive performance between different conditions of SOT between ALL survivors and controls. For this analysis, the independent variables will be the group (survivors and controls) and task condition (Cognitive only and added cognitive load during dynamic posturography), the dependent variables will be cognitive performance in each condition of the SOT (cognitive performance in condition 1 through

    Traumatic Brain Anatomy Case Study

    When Ingrid becomes discharged from the inpatient facility, her family will receive education and training on how to properly assist Ingrid with transfers and independent walking in various household locations, such as the bedroom, bathroom and kitchen. This will include home modifications, assistive devices, and adaptive technologies, such as grab bars placed in the bathroom and a stair transport chair designed to help maintain Ingrid’s sitting posture, as a means to maximize her occupational performance and enhance her safety. This intervention is suitable with the rehabilitative frame of reference because it helps Ingrid maintain her current abilities through the use of compensatory strategies. Although occupational therapy services serve as a positive factor in the recovery for clients with traumatic brain injury, 50% of clients unable to walk and 37% of clients were only able to walk up stairs in a house, proving that the rehabilitative frame of reference is apt for this intervention (Haffejee, Ntsiea, & Mudzi,…

    Post Traumatic Vertigo Case Study

    I chose to do my discussion on the 50-year-old women. When talking with the patient I would first gather all the subjective data. It’s important to get to the source of the problem and by discussing her signs and symptoms we have a clearer picture of what diagnostic tests should be done. Her main complaints were headache, decreased range of motion in her neck, vertigo, hearing loss in one ear, and uncontrolled eye movements. She has also been in a motor vehicle accident three days ago. Being that she was in a MVA, my first instinct would be trauma. I feel that before any other tests are performed or manipulation of assessing her head, she should have a stat CT scan to rule out any life-threatening issues to her head, neck and or spine. Depending on the results of the CT scan, we would know if further advanced imaging tests are needed, like an MRI.…

One big issue that takes controversy opinions around is the effectiveness of sustained end-range rotation on crainocervical arteries and if it is affecting on the amount of blood to brain. In this abstract can defined the sustained end-range rotation as a pre-manipulative screening test tool that utilise to examine insufficiency of brain blood supply on crainocervical arteries as vertebrobasilar arteries and internal carotid arteries through three different neck positions. According to (Thomas LC, et al. 2015) explains a relationship between manipulation of neck especially rotation and decrease blood flow in VAs and ICAs. However, several…

    Immune Disorders: Multiple Sclerosis

    These stages include assessment, diagnosing, planning, implementation and evaluation. When assessing a patient with multiple sclerosis a nurse should take into account the, “physical, cognitive, sensory, bowel and bladder function... [which is the] baseline functional assessment [that] can be used to compare [against] future neurological examinations” ("National Guideline Clearinghouse", 2015). Subjective data is collected through past health history and current medication information. Objective data may be assessed by neurological and muscular skeletal examinations which includes scanning for speech, tremors, decreased hearing, spasticity, hyperreflexia, muscular weakness, paralysis, spasms, foot dragging, dysarthria, and decreased bowel and bladder function (Lewis, 2014). The assessment of multiple sclerosis is systematic and ongoing. The signs and symptoms of multiple sclerosis affect how a nurse would assess and manage the disease…

Motor control, a high-load sling, and general exercise were found to be equally effective as well (Unsgaard-Tøndel et al., 2010). Saner et al.

    The Influence Of Cognitive Maps

    Short term memory loss impacts can be seen in issues such as forgetting names, losing train of thought, forgetting past conversations, misplacing objects, difficulty learning new skills, and getting lost. Short term memory loss due to brain injury relates back to cognitive mapping, especially when considering that losing one’s way is a major symptom; meaning that a cognitive map has been affected. Another factor that can interfere with creating and recalling a cognitive map due to brain injury is difficulty with attention and concentration. Once affected by a brain injury, a person can become easily distracted, suffer from information overload, and have difficulty in areas of multitasking. This can stifle not only the creation of cognitive maps, but later create trouble when attempting to recall said cognitive map (Cognitive Impairments,…
