The Relationship Between Upper Extremity Anthropometric Measurements and Reaction Time
An observational study of Healthy Persons, run by Kutahya Health Sciences University at 1 site in Turkey (Türkiye).
Trial summary
Our study aimed to examine the relationship between upper extremity anthropometric measurements and reaction time in healthy individuals. Also, we aimed to investigate whether there are differences between dominant and non-dominant upper extremity anthropometric measurements and reaction time. Read more about this study

About this study
Our study aimed to examine the relationship between upper extremity anthropometric measurements and reaction time in healthy individuals. Also, we aimed to investigate whether there are differences between dominant and non-dominant upper extremity anthropometric measurements and reaction time.
Read the detailed description
Reaction time is the time between the presentation of a stimulus and the generation of a response. It consists of various processes including sensory processing, information processing, decision-making, and motor response. Reaction time is also affected by various factors such as task complexity, attention level, and the individual's condition. Muscle strength has been shown to affect reaction time in different age groups. Studies in the literature have determined that reaction time is a factor affecting performance in athletes, individuals with orthopedic diseases, and the elderly. Therefore, identifying the factors affecting reaction time is important. We aimed to investigate the relationship between upper extremity anthropometric measurements and reaction time in healthy individuals.

What is being measured
The primary outcome is the main question the study is designed to answer.
Upper Extremity Anthropometric Measurements
Upper extremity length measurements were performed twice and the average score was recorded. Total upper extremity, arm and forearm length measurements were taken with a Harpenden anthropometer. Hand, palmar (palm), thumb, index finger, middle finger, ring finger, little finger, hand width and hand opening length measurements were taken with a digital caliper (Dasqua, Italy).
Measured: Baseline
Secondary outcomes (1)
Reaction time measurement
Reaction time was assessed using the Blazepod device (Blazepod 1.0). A four-LED evaluation panel was used for measurement. Individuals were asked to turn off the LEDs as quickly as possible while in a seated position. The average time between the LEDs turning on and the individuals touching and turning them off the illuminated sensors was recorded by the device in milliseconds for each hand separately. A one-minute rest period was given between tests. The test was conducted twice, and the best score was recorded. The dominant and non-dominant upper extremities were evaluated, respectively
Measured: Baseline
