Effects of Different Stimuli on Muscle Activation, Hand Grip Strength, Reaction Time, and Hand Function

The study will include three separate intervention groups: an ice application group, a vibration application group, and a control group. Accordingly, three groups were randomly generated using the Research Randomizer software. To determine the group allocation of the participants, individuals will be asked to draw a number from a bag containing numbers, each written only once. The intervention corresponding to the drawn number will be applied to the participant. All interventions will be administered by the researcher Demet Öztürk, while the outcome measurements will be evaluated by the researchers Seda Baktır Doğan and Mustafa Sarı. The interventions and assessment procedures will be conducted in separate rooms in order to ensure assessor blinding. Participants included in the study will first complete a Demographic Data Form. This form will record demographic information including age, sex, body weight, height, dominant side, alcohol consumption status, medical history, and family history. Following the relevant tactile stimulus application, participants' hand grip strength, muscle activation, hand function, and upper extremity reaction time will be assessed.
