To begin, select individuals who can stand erect unsupported for at least 30 seconds and are able to follow the instructions. Perform the tests in a well-lit room with a firm surface, such as vinyl tile or industrial carpeting. For clinical tests of sensory integration and balance, or CTSIB, use a timed device such as a stopwatch or a digital timer.
To conduct the CTSIB use medium density foam, known as temper or memory foam. Ask the participant to stand upright with feet together, side by side, arms crossed at the waist, and each hand holding the opposite elbow. After the individual stands on the foam conduct test trials with arms crossed at the waist and look straight ahead.
To steady the individual, place a hand on the individual's shoulder while he or she looks straight ahead. Initiate the test trial by saying, Close your eyes, and remove the hand from the person's shoulder. Then say, Go, and start timing the trial for up to 30 seconds.
Perform this trial once. For each CTSIB condition, measure the time an individual can remain upright without making an error up to 30 seconds. Perform Trial 1 with the head stationary.
Before commencing Trial 2, ensure the participant is standing on the floor with eyes open and practice nodding the head along to the rhythmic sounds of the application until the head movements match the sound frequency of 0.3 hertz. To begin Trial 2 instruct the participant to stand on foam with feet together and arms crossed. Start the metronome or metronome application before the participant closes his or her eyes.
And provide stabilization by placing a hand on the person's shoulder. Then ask the participant to nod his or her head in rhythm with the metronome's beat upon hearing the cue, go. Lift the hand from the individual's shoulder.
Say, Go, and start the timer simultaneously. Post-trial, offer a rest period by letting the person step off the foam and sit down, if desired. Carry out the third trial, shaking the head left to right at a frequency of 0.3 hertz to the rhythm of the sound, followed by the steps performed during Trial 2.
Ensure the room has a clear path of 4.5 meters forward and one meter on either side of the individual taking the test, demonstrate the procedure by taking 3 to 5 steps, placing one foot, heel to toe in front of the other foot each time. Ask the individual to do a practice trial with eyes open, arms crossed at the waist without wearing shoes, but should have socks on for good hygiene. Next, ask the person to place one foot directly in front of the other, maintaining no more than 2.4 centimeters between the front and rear feet.
Conduct the test trial where the individual stands with feet comfortably apart wearing socks and arms crossed. Ask the person to close his or her eyes and take 10 heel-to-toe steps upon hearing the command, Go.Monitor the total number of correct tandem steps out of 10, including not consecutive steps. For incorrect steps, tally them silently using the fingers of one hand, like how children count using their fingers.
Then perform the analysis by comparing the individual scores to the already established data and determine if the scores are normal, or abnormal for the individual's age group, and for CTSIB and tandem walking for each condition. The data for the three conditions of CTSIB:head still, head yaw, and head pitch showed that young children had reduced scores for both tests compared to children aged 10 and older. Scores declined in the middle and especially older age.
The data from tandem walking showed that young children and older subjects had fewer correct tandem steps than subjects aged 10 to 59 years.
