Details and patient eligibility

About

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.

Full 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.

Enrollment: 42 patients

Sex: Female

Ages: 18 to 25 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

1. Female individuals aged 18-25

Exclusion criteria

1. Having an open wound in the area where local vibration is applied
2. A history of previous or current upper extremity injury
3. Use of anti-inflammatory drugs
4. Having a diagnosis of epilepsy

Trial design

Primary purpose: Treatment

Allocation: Randomized

Interventional model: Parallel Assignment

42 participants in 3 patient groups

Sham Vibration Group

Sham Comparator group

Description:

In this group, sham vibration will be administered following the muscle fatigue protocol. The vibration device will be activated but positioned close to the muscle without direct contact for a duration of 10 minutes. Participants will be told that they are receiving treatment with an electromagnetic vibration device.

Treatment:

Other: Sham Local Vibration

50 Hz Local Vibration Intervention Group

Experimental group

Description:

Participants in this group will receive 50 Hz local vibration following the muscle fatigue protocol. The local vibration will be applied along the flexor carpi ulnaris muscle for a duration of 10 minutes.

Treatment:

Other: 50 Hz Local Vibration

100 Hz Local Vibration Intervention Group

Experimental group

Description:

Participants in this group will receive 100 Hz local vibration following the muscle fatigue protocol. The local vibration will be applied along the flexor carpi ulnaris muscle for a duration of 10 minutes.

Treatment:

Other: 100 Hz Local Vibration
