Local Vibration in Cervical Radiculopathy

The effect of local vibration intervention on patients' neck pain will be evaluated using the Patients' Global Impression of Improvement Scale. In this scale, patients will be asked to mark their perceived change in pain using the following options: 'very much better,' 'much better,' 'a little better,' 'no change,' 'a little worse,' 'much worse,' and 'very much worse.'

The effect of local vibration intervention on patients' upper limb pain will be evaluated using the Patients' Global Impression of Improvement Scale. In this scale, patients will be asked to mark their perceived change in pain using the following options: 'very much better,' 'much better,' 'a little better,' 'no change,' 'a little worse,' 'much worse,' and 'very much worse.'

The effect of local vibration intervention on patients' paresthesia will be evaluated using the Patients' Global Impression of Improvement Scale. In this scale, patients will be asked to mark their perceived change in paresthesia using the following options: 'very much better,' 'much better,' 'a little better,' 'no change,' 'a little worse,' 'much worse,' and 'very much worse.'

The immediate and short-term effect of local vibration intervention on cervical range of motion will be measured using a 10-inch standard manual goniometer. To measure cervical flexion and extension range of motion, the pivot point of the goniometer will be placed at the external auditory meatus. The fixed arm of the goniometer will be held vertically, and the moving arm will follow along the base of the nostrils. For measuring cervical rotation range of motion, measurements will be taken from behind the participants. The pivot point of the goniometer will be placed at the vertex, while the fixed arm will be kept parallel to the acromion, and the moving arm will follow along with their nose. Lateral flexion range of motion will be taken in front of the participants. The pivot point of the goniometer will be placed over the sternal notch, with its fixed arm parallel to the acromion, and its moving arm will follow along the tip of the participants' nose.

The potential impact of local vibration intervention on patients' pain thresholds will be evaluated using an analog algometer. Pain threshold measurements will be taken at the upper trapezius muscle. The algometer will be positioned perpendicular to the measurement areas. Three measurements will be taken for each region, with a half-minute interval between measurements. The average of the three measurements will be calculated and recorded. A change of 20-25% in the algometric measurement values will be considered significant.

The effect of local vibration intervention on the viscoelastic properties of patients' upper trapezius will be measured using the myotonometer (MyotonPRO). The upper trapezius myometric measurement will be taken with the patient seated on a chair with hands placed over knees, and measured from the midpoint between the C7 spinous process and the acromion.
