U.S., April 10 -- ClinicalTrials.gov registry received information related to the study (NCT07521228) titled 'Acute Effects of Smartphone-Delivered Local Vibration on Hand Sensorimotor Performance' on April 03.
Brief Summary: This study investigates the acute effects of smartphone-delivered local vibration on hand sensorimotor performance in healthy young adults. Using a custom-developed iPhone application, three vibration frequencies (80 Hz, 150 Hz, and 220 Hz) are applied to the dominant hand in a randomized crossover design with a minimum 48-hour washout between sessions.
The primary aim is to evaluate frequency-dependent dose-response effects on hand grip strength. Secondary aims include assessment of two-point discrimination (tactile...
