Parkinson's disease (PD) is the second most common neurodegenerative disease that causes a progressive decrease in motor functions, which is caused by the influence of dopaminergic pathways in the substantia nigra (SN). Motor and non-motor symptoms seen in PD seriously affect patients negatively. Proprioception, which is one of the deep senses, is known to help maintain body verticalization in the sense of posture and movement and has a primary importance in the regulation of motor activities. Depending on the progression of the disease, flexion of the body is triggered as a result of the deterioration of proprioception over time. It is suggested that the losses in proprioception may result from the inability to properly regulate motor control and body reflexes. Therefore, the assessment of proprioception plays an important role in assessing changes in postural instability, gait and fall risk. It is said that while peripheral muscle feedback is preserved in Parkinson's patients, there is deterioration in integration in the central. Changes in the supraspinal processing of proprioceptive input in PD have been demonstrated by analyzing the effect of mechanical vibration applied to the tendon of a stretched muscle during voluntary movements. Vibrator stimulation activates muscle spindle afferents, particularly primary endings. It is also stated that muscle feedback is not only related to the movement performed, but also to the response induced by vibration. In line with this information, vibration applications have been added to the treatment of PD in recent years with the aim of stimulating postural adjustments through the application of an external proprioceptive input. It is selectively used in neurological rehabilitation because of the effect of local vibration training on spinal excitability. When the literature is examined, it has been determined that the studies on the effects of local vibration applied to the neck region on posture, balance, proprioception and other sensory profiles are insufficient, especially in individuals with Parkinson's disease. In this project, it is aimed to guide professionals working with Parkinson's disease in the management of this disease by determining the effects of cervical stabilization and local vibration application to the cervical region on motor symptoms and sensory profile in individuals with Parkinson's disease.

Stabilization exercises, which form the basis of spinal stabilization training, increase the strength and endurance of the postural and stabilizer muscles by using the basic principles of motor learning, and improve balance control in stable and unstable positions. In addition, stabilization exercises include kinesthetic training and functional training. Spinal stabilization training is very important for proper control of extremity movements. It is also an important factor in the formation of proper spinal posture and the neutral position required for the spine. In cervical region problems, cervical stabilization exercises that activate the deep neck flexors (longus colli and longus capitis) can be applied. Cervical stabilization training improves the cervical proprioception sense as well as strength and endurance, thereby reducing joint position sense error.
Vibration applications have also started to be used for treatment purposes. Therapeutic vibration produces minor changes in skeletal muscle length. Vibrations elicit a response called the "tonic vibration reflex", which includes activation of muscle spindles, neural signals by Ia afferents, and activation of muscle fibers via large α-motor neurons. The tonic vibration reflex can also cause an increase in activation of motor units through activation of muscle spindles and polysynaptic pathways. It is well known that the input of the proprioceptive pathways (Ia, IIa and possibly IIb) plays an important role in the production of isometric contractions. The increase in isometric strength after application of vibration with extensive sensory stimulation may be the result of more efficient use of the positive proprioceptive feedback loop. It can be predicted that the increased muscle strength after vibration application is due to neural adaptation.
Telerehabilitation is a method that aims to provide rehabilitation to patients/clinicians by reducing obstacles such as distance, time and cost by using information and communication technologies. Telerehabilitation enables patients who cannot access rehabilitation due to geographic, economic or physical disabilities to benefit from rehabilitation services. The COVID-19 pandemic has highlighted the importance of telerehabilitation practices. In order to minimize the risk of transmission in the COVID-19 pandemic, the physical activity levels of individuals have decreased and their access to rehabilitation services has been restricted by the restriction of social life.

Change of cervical region joint position sense
The subject sits upright in a comfortable position with arms at the side. First of all, the active maximum range of motion of the subjects in 6 different positions is determined separately, and 65 percent of this value is calculated. The subject is then asked to close his eyes and the subject's head is slowly and passively brought to the point previously determined by the physiotherapist. The head of the subject is held for three seconds at the passively brought point and asked to feel the joint position. Then, the subject's head is brought back to the neutral position and asked to actively bring it to that point, which is passively brought. The difference between the point where the phenomenon comes from and the previously determined reference point is calculated and determined as the insertion position sense error.

Vibration sense will be evaluated using tuning fork with a frequency of 128-Hz. After explaining how the test will be done and what is requested from the patient, the tuning fork to be used during the test will be placed on the patient's areas to be tested in order for the patient to feel and learn the vibration.

Change of Craniocervical Flexion Strength
This test tests the activation and endurance of the deep neck flexors. It is performed with the individual lying in the supine hook position and the neck in a neutral position. The uninflated pressure sensor is placed between the projection of the earlobe and the chin and inflated to 20 mmHg. The person is asked to do the movement lightly and slowly (as if to nod, as if to say yes) and look towards their eyes and feet. Activation score is calculated based on the pressure level that the person is able to achieve and can do 10 repetitions for a 10-second period and deep cervical flexor recorded as a measurement of the strength of the muscles.

Change of Endurance Cervical Flexor Muscles
The case is performed in the supine hooked position, with the hands free on the abdomen. The subject is asked to raise his head slightly at a height of about 2 cm, and after this position is taught, he is asked to do a slight (30%) craniocervical flexion as if he were saying yes. The time it takes to maintain the position while maintaining the craniocervical flexion movement is recorded in seconds.

Change of Basic Digital Inclinometer - Inclinometer
An "inclinometer" device will be used in the evaluation of thoracic kyphosis and lumbar lordosis. In order to determine the thoracic kyphosis, the "inclinometer" will measure the spinous processes of the C7-T1 and T12-L1 vertebrae, and the degrees found will be summed and the degree of kyphosis will be calculated. In order to determine the lumbar lordosis, measurements will be made between the spinous processes of the T12-L1 and S2-S3 vertebrae and the degree of lordosis will be calculated by adding the degrees found.
Time frame: baseline - change at 6 weeks - 4 weeks later
Change of Baseline Inclinometer
A "Baseline Scoliometer" device will be used to evaluate the cervical curvature of the cases. For cervical lordosis, the graduated dial will be set parallel to the ground. The top bar of the device will be locked and inserted into the spinous process of the C4 vertebra. The lower bar will be adjusted in height so that it is in the spinous process of the C7 vertebra. The lower bar will be loosened until the indicator shows zero degrees, locked at the point where it points zero, and the measurement will be recorded in cm.
