Intervention: Tuning Fork Vibration Sense
Description: Vibration sense will be assessed using a traditional 128 Hz tuning fork. When the stem of a 128 Hz tuning fork is placed on the dorsal aspect of the interphalangeal joint of the hallux, a healthy person can feel the vibration as long as it continues (15-20 seconds). In conditions leading to peripheral nerve damage (such as polyneuropathy), vibration sense is impaired. The examiner holds the proximal end of the tuning fork with one hand, while the distal end is struck strongly against the palm of the examiner's other hand. The examiner should try to strike the tuning fork with consistent force for each assessment. After striking, the tuning fork is placed just proximal to the nail bed, on the dorsal aspect of the distal phalanx of the hallux.Before applying the tuning fork, the participant is instructed to verbally respond with yes if they can initially feel the vibration, and they should also indicate now when they stop feeling the vibration.

Intervention: Timed Up and Go Test
Description: The Timed Up and Go (TUG) test is designed to measure dynamic balance based on the time it takes for patients to stand up and walk, providing quantitative results. The patient starts the test by sitting on a standardized chair (46 cm high). During the test, the patient is instructed to stand up from the chair, walk 3 meters away, turn around, and then return to sit back down on the chair. The duration of this process is measured. Lower values indicate better stability. A cutoff value of 13.5 seconds has been used to identify high fall risk in the TUG test.

Intervention type: DIAGNOSTIC_TEST
Intervention: Physical Examination
Description: Manual Muscle Test: Muscle strength is evaluated using the MRC (Medical Research Council) muscle strength scale.~Reflexes:Patellar reflex: The reflex hammer is struck on the patella, and extension of the leg is observed. Achilles reflex: With one hand, the patient's foot is lightly dorsiflexed, and the Achilles tendon is struck; plantar flexion is observed in the ankle.
