The intent of the journal was experimentation to venture into age-related circumstances over the lifespan of development, this was an aspect that was previously constrained to specific developmental stages. Additionally, the article was informative in a variety of other postural control factors as well as age-related circumstances; other information was gathered that distinguished a variation between genders, and bodily characteristics (e.g., BMI, body mass) as well as a variation regardless of the sex.
Method:
Previously, other experiments would take a small number of subjects to generate their data and it would be a detriment to their results. The methods seen in this experiment called for 1724 subjects (737 men and 987 women), all of which they collected from the surrounding institutions. All of the subjects who had participated established a criteria of being asymptomatic, no medical problems (injury/diagnosis), and no disorders of any kind. Additional criteria for the older persons dealt with evaluating previous medical history, falling episodes within the past 6 months, independent living situation, and ability to mobilize on their own.
The study measured postural regulation using the Interactive Balance System (IBS); the system used four …show more content…
After a several investigations, the mean value of the postural regulation (IBS) was subtracted from the force-time signal. Then the data was taken and referenced with the FFT frequencies. The FFT was determined to be directly correlated to the signal of the motor output stability. Within the study the investigators made it clear that NO (Normally bipedal stand with open eyes) was the only relevant position for the study; the involvement of all the other postural subsystems for regulation was the reason for this distinct
