The distance travelled by an object moving at constant speed can be calculated using the equation:ĭistance travelled = average speed × time taken The speed of an object can be calculated using the equation: Calculations involving space, distance and time A light breeze moves at perhaps 3 m/s, but a gale would be more than 20 m/s. A typical value for the speed of sound in air is about 330 m/s. The speed of the wind and the speed of sound also vary. It is not only moving objects that have varying speed. Some typical values for speed in metres per second (m/s) include: Method of travel They may speed up, slow down or pause for traffic. When people walk, run, or travel in a car their speed will change. Like distance, speed also does not have an associated direction, so it is a scalar quantity. Speed is the rate of change of distance – it is the distance travelled per unit of time.
It does not include an associated direction, so distance is a scalar quantity. DOI: 10.1016/j.apmr.2018.07.Distance is how far an object moves.

You then have to repeat the same movement with your eyes closed.Ī physical therapist can assess proprioception with special equipment that controls and measures movements of other body parts, such as your arms, back, legs, and feet. The tester will hold the sides of your big toe and perform up and down movements while you watch. To perform the test, touch each of your fingers to your thumb, starting with your forefinger. This test is often used on children and adults. Then, you’ll be asked to touch the placed thumb with your other thumb and forefinger while your eyes are shut. For this test, the tester will place one of your hands in a certain position. It includes the horizontal gaze nystagmus (HGN) test, which involves following a slowly moving pen or other object with your eyes the walk-and-turn (WAT) test, in which you walk a few steps in a straight line with one foot in front of the other and the one leg stand (OLS) test, which is simply standing with one foot raised off the floor. The standardized field sobriety test (SFST) is a battery of three tests. One such test involves closing your eyes and touching your nose with each of your index fingers.

This may involve one or a series of tests often used by police officers to evaluate suspected drunk drivers. If you lose your balance during that time, it’s considered a positive result.

The type of test used will depend on the area of the body affected. They may also use one or more proprioception tests. If you have symptoms of proprioception disorder, such as balance issues or a lack of coordination, your doctor will ask about your medical history, including any preexisting medical conditions and recent injuries or surgeries.Ī healthcare professional, such as a doctor, physical therapist, or occupational therapist, will perform an examination, including a neurological exam.
