Summary

This study aims to investigate the acute effects of local vibration applied after induced fatigue of the wrist flexor muscles on grip strength and upper extremity reaction time.

Detailed description

This randomized controlled study will be conducted with a minimum of 42 participants who meet the inclusion and exclusion criteria. Participants will be randomly assigned to one of three groups: control, 50 Hz local vibration, or 100 Hz local vibration.

Conditions

• Muscle Fatigue

Interventions

Type	Name	Description
OTHER	100 Hz Local Vibration	Participants in this group will receive 100 Hz local vibration along the flexor carpi ulnaris muscle for a duration of 10 minutes.
OTHER	50 Hz Local Vibration	Participants in this group will receive 50 Hz local vibration along the flexor carpi ulnaris muscle for a duration of 10 minutes.
OTHER	Sham Local Vibration	Participants in this group will receive sham vibration following the muscle fatigue protocol. The vibration device will be turned on but held near the muscle without making contact for 10 minutes. Participants will be informed that they are being treated with an electromagnetic vibration device.
