ClinConnect Summary

This study is looking at how caffeine use might affect hand reaction speed and fine motor skills, like how quickly and accurately you can move your fingers and hands. Researchers want to see if people who drink a lot of caffeine every day have slower or less precise hand movements compared to those who drink less. To do this, they will test reaction time using a simple hand response test and check manual dexterity with a pegboard task, which involves placing small pegs into holes as quickly as possible.

The study is open to healthy university students between 18 and 30 years old. People with any hand or nerve problems, past wrist surgery, or visible hand deformities won’t be able to join. If you participate, you can expect to take part in some quick and easy tests that measure how fast and accurately your hands respond. This study is not yet recruiting, but it’s designed to help us understand whether caffeine habits might influence hand skills important for daily activities.
