Velocity Step Lab Report

Rinne test involves tuning fork to be placed on the mastoid bone, and ask when patient no longer hears the vibration,and checks for air conduction and bone conduction

2. (5 pts) List and explain the names and affiliations of the various characters/stakeholders in this story – I’m looking for us to use the story to map out the complexities that are generally associated with solving public health puzzles – the stakeholders you list and explain here should apply to many of the cases we consider going forward.

The subjects than used the SSP test to determine their speed when executing and voluntarily inhibiting a motor response. It involved two concurrent tasks which gauge reaction time as well as accuracy.

COMPARISON OF LATENCY PERIOD AND AMPLITUDE OF TWO SIMPLE SPINAL REFLEX PATHWAYS AND THE INFLUENCE OF THE JENDRASSIK MANEUVER ON EACH RESPONSE

In contrast to in clinical settings, in research settings it is possible to easily assess the absolute contraction speed and velocity of the stretch reflex using

Slope determination is a valid way to calculate density because the slope of the data and the actual slope were close in value. When looking at the slope of the graph with the points, they were all relatively close. Three of the five point were even on the slope line. The formula of (y2-y1/x2-x1) allowed the finding of the slope of the line graphed and it also allowed the comparison to the actual slope of silver. This allowed the calculation of the percent error and also to see how effective slope determination really is. The slope of silver was 10.5g/cm³ and the slope of my findings was 10.15g/cm³. The percent error was low at 3.3% which points to slope determination

Will different gloves with different amounts of friction have an affect on the amount of times a football is caught? If more friction is used, the amount of passes caught will increase, and the amount of passes dropped will decrease when the catch rate is the function of the gloves being used. The independent variable of this experiment is the amount of friction of different gloves. The dependent variable will be the amount of times the football is caught after being thrown. The experimental control will be using no gloves to add friction, and measuring the amount of passes caught.

The higher the temperature got the lower the number in minutes. The graph showed a steady decline in its line.

The purpose of the experiment was to use previous knowledge of velocity yo perform kinetic energy calculations, make calculations of gravitational potential energy, and to determine what affects GPE and KE more. What was determined to be true was that the potential energy was larger than the kinetic energy and that velocity had a greater effect on the kinetic energy because velocity doubles in the kinetic formula. At first the group had to convert the original ball’s mass from grams to kilograms by dividing by 1,000. Then the group had to determine the height of drop for each location and calculate the potential energy of each ball by doing

When the head is tilted laterally, the eyes compensate by rotating in the opposite direction. This is an orienting reflex that tends to align the eyes with the spatial vertical. Schworm, Ygge, Pansell, and Lennerstand (2001) found that ocular counter-roll can be observed when individuals tilt their heads at an angle, with the maximum amount of torsion detected at a 45 degree angle being 10 degrees. The experimenters also found that the average amount of counter-roll is four to seven degrees. Another factor in ocular counter-roll responses is the amount of time the head has been at a particular orientation. Markham and Diamond (2002) found that the magnitude of ocular counter-roll was highly affected by whether or not the head was in position for a long time or was still in motion, with dynamic rotation inducing a higher degree of counter-roll on

Figure skaters’ VOR gain was 27% less than the control group during sinusoidal stimulation and the skaters’ responses are 10° phase advance when compared with the controls. VOR gain is 32% lower for the skaters’ during the velocity step, but there was no notable difference in the TC between the groups. The MS score is much lower for the skaters’ after vestibular stimulation (2.8+/-2.8 vs. 16.2 +/- 13.7). The findings were striking in the way that during the velocity step test the figure skaters’ gain is 32% lower than the control group. According to the researchers, this is quite significant. The figure skaters are much less likely to experience MS and VOR gain because of these findings. The results show that despite the young ages of the figure skaters, they are already showing signs of vestibular habituation. The hypothesis was generally supported because the VOR modifications seen in the skaters are in agreement with previous experiments on

Another modification that can be applied to this test is to measure the hip position goniometrically or the patient can passively flex the hip

Phys 221 Section September 12, 2016 Experiment 1: Motion Reba Chamblee Partner: Erin Jacoby   Abstract: In the first part of the experiment, a stop watch, meter stick, and various objects of different masses were used to estimate time, length, and mass which are the fundamental quantities of mechanics. The next part consisted of comparing more sophisticated techniques, such as a Vernier caliper to a 30cm ruler, to measure the average volume and mass of a wooden block/metal block and the diameter of 5 circular objects. While calculating these measurements, the inherent uncertainty of these different methods of measurement was learned.

The vestibular system is responsible for gaze stability (head movements), posture stability,spatial orientation, and navigation, which are all controlled by three reflexes within the vestibularsystem.1 If one of these system’s signals are interrupted, a person may experience bouts ofdizziness, unsteadiness, or decreased dynamic visual acuity (DVA) resulting in increased risk forfall, decreased confidence, and social withdrawal in healthy individuals and in those withvestibular dysfunction. The vestibular ocular reflex (VOR) is the primary system that gazestabilization exercises (GSE) have been shown to have an effect on due to the exercises exposingpatients to retinal slip. A retinal slip occurs when an object moves off of the fovea of the

Outlier was defined as a datum that its’ standard deviations was above or below 2.5 standard deviations than the mean; therefore, three participants were excluded from the data set of the perceptual task. To assess the proprioceptive drift, a paired samples t-test was used with condition (synchronous versus asynchronous) as the independent variable and drift distance of blu tack as dependent variable. Analysis revealed that the participants in synchronous condition (M= 1.98 cm, SD= 3.20 cm) drifted more closer to the rubber hand than in asynchronous condition (M= 0.12 cm, SD= 1.87 cm), t (48) = -3.42, p = .001, two-tailed test.
