Dystonia is involuntary movements characterized by posture abnormalities or repetitive movements as a result of continuous or intermittent simultaneous contraction of opposing muscle groups. Dystonic movements are twisted and twisted in a certain pattern. Dystonia is named in different ways according to its distribution in the body. Cervical dystonia is the most common form of regional dystonia and can be defined as involuntary movements of the head in normal upright posture.Cervical dystonia has different names according to the posture of the neck (torticollis, laterocollis, anterocollis and retrocollis). These different postures can be seen individually as well as together.Pain in cervical dystonia is seen in approximately 70% of patients, and this condition is closely related to involuntary contractions of neck muscles and neck posture disorder. Fatigue, anxiety, unhappiness, decreased self-efficacy and limitation in daily living activities due to decreased neck movements are the main causes of disability in patients with cervical dystonia. The first-line treatment of cervical dystonia consists of injecting botulinum toxin type A into the relevant muscles to alleviate these complaints.There is increasing evidence that range of motion, stretching, and relaxation exercises, in addition to botulinum toxin therapy, have beneficial effects on pain and disability in patients with cervical dystonia.In this study, patients with cervical dystonia who received botulinum toxin type A injection will be divided into study group and control group.The patients in the study group will be given stretching, strengthening, breathing and rhythmic coordination exercises for the muscles involved. (Personalized exercise program) In the control group, only breathing and rhythmic coordination exercises will be given and the two groups will be compared.Thus, it is aimed to investigate the effect of a personalized exercise program on clinical findings and the patient's quality of life.
