Brief summary

The Smart Speed device developed at Zafer Teknopark in Turkey was developed to objectively assess reaction time. The aim of this study was to evaluate the validity and reliability of the Smart Speed device in comparison with BlazePod and Nelson Reaction Test.

Detailed description

The capacity to perceive, analyze, and react to a signal is referred to as reaction time. Reaction time is influenced by many factors such as visual and auditory factors. It is also influenced by individual factors such as age, gender, body mass index, attention and fatigue. Having reaction time within normal limits is very important for maintaining activities of daily living. BlazePod is a valid and reliable device for the assessment of reaction time. The Nelson Reaction test is also a valid and reliable test frequently used in the clinic for the assessment of reaction time due to its simple and rapid application. The Smart Speed device developed at Zafer Teknopark in Turkey was developed to objectively assess reaction time. The aim of this study was to evaluate the validity and reliability of the Smart Speed device in comparison with BlazePod and Nelson Reaction Test.

Interventions

OTHERValidity and reliability study

Test-retest method will be used to assess reliability. For this purpose, participants will be re-evaluated one week later with the Smart Speed device. For validity assessment, concurrent validity and agreement between measurements will be evaluated. Concurrent validity will be assessed by correlation analysis and agreement between measurements will be assessed by Bland Altman.
