Brief Summary

Auricular Vagus Nerve Stimulation, a non-invasive method, will be used in the study. Studies have shown that vagus nerve stimulation combined with a large vagal nerve network can have a neuromodulatory effect that will activate some natural protective pathways to improve health. Clinically, vagus nerve stimulation is FDA-approved for epilepsy, treatment-resistant depression, and morbid obesity. Since OSS dysfunction is also involved in the etiology of DO and there is no study on the effectiveness of vagus nerve stimulation in this disease, this study is planned to reveal the effectiveness of auricular vagus nerve stimulation and home exercise program in DO patients.

Conditions

Being in the 18-50 Age Population; Being Diagnosed With Frozen Shoulder by a Specialist Physician; Volunteer to Participate in the Study

Keywords

Outcome Measures

Primary Outcomes (7)

• kinesiophobia assessment

  Tampa Kinesiophobia Scale were used. The Tampa Kinesiophobia Scale (TKS) is one of them, and it's commonly used in the literature to assess kinesiophobia. It has 17 questions designed to assess fear of moving.

• Pain Assessment

  Pain Assessment Visual Analogue Scale (VAS) was used. On a 10-centimeter (cm) horizontal line, start 0 (no pain) and finish 10 (unbearable pain) are marked and the subjects were asked to place a mark on this horizontal line according to the degree of pain they felt. The point marked on the line was then measured with the help of a ruler and recorded as the VAS value in cm.

• Depression Assessment

  Depression Severity Assessment, The Beck Depression Inventory (BDI) was employed, which consists of 21 questions. The scale has a range of 0 to 84 points.

• joint range of motion assessment

  ROM will be evaluated with the goniometric measurement. This measurement method is an objective method used in the clinical evaluation of joint range of motion. Shoulder flexion, extension, abduction, adduction, external and internal rotation movements of the patients will be measured 3 times passively and actively with a universal goniometer.

• functional limitation and disability status assessment

  In our study, the Arm, Shoulder and Hand Problems Questionnaire (DASH), which is more preferred in the clinic, was used to evaluate upper extremity functional limitation and disability, which consists of 3 parts. The questionnaire consists of 30 questions that determine the function score in the first part; 21 questions about difficulty in activities of daily living, 5 questions about symptoms (pain, tingling, stiffness, activity-related pain), each of the remaining questions evaluates the patient's social function, work, sleep and self-confidence. The second part of the questionnaire is answered optionally and is a business model consisting of 4 questions. In the third part of the questionnaire, there is a section consisting of 4 elective questions that determine the disability level of patients who are sports-musician models, who want high performance, who are involved in sports or music.

• Quality of Life assessment

  In our study, the widely preferred SF-36 form, consisting of 36 items, was used to evaluate the quality of life in patients with musculoskeletal disorders, whose reliability and validity have been demonstrated by studies. The 36 items in this form cover 8 different health-related dimensions: physical, emotional and social function, physical role, mental health, general health, pain and vitality. For these dimensions, the scores of the items are coded and converted into a scale between 0-100 points. The scale that evaluates the scores of each subgroup between 0-100; 0 indicates "worst health" status, 100 indicates "best health" status.

• Shoulder Pain and Disability Assessment

  The Shoulder Pain and Disability Index, developed by Roach et al. in 1911, was used to assess the level of disability by questioning the level of limitation experienced by the participants during personal carrying, care and dressing activities, and to measure current shoulder pain and disability. The Spadi scale consists of 2 subscales of pain (5 questions) and disability (8 questions) and 13 subheadings. Pain and disability subscales are calculated between 0 (no pain) - 100 (worst pain imaginable). As a result of the survey, 3 different scores are obtained as Obstacle, Pain and Total score, each of which is scored separately. The answers given to the questions in the scale are calculated as the last percentile. The higher the total score on the scale, the higher the person's level of pain or disability.

Study Arms (3)

exercise therapy group

EXPERIMENTAL

Exercise therapy group; joint range of motion exercises including the upper extremity, strengthening, stretching, isometric and posture exercise program will be given. These exercises are in the form of a home program and will be asked to do 2 sets a day, 5 days a week, and 10 repetitions of each movement for 4 weeks.

Device: vagus nerve stimulation

vagus stimulation group

EXPERIMENTAL

To the patients in the vagus stimulation treatment group; Auricular vagus nerve stimulation in the physical therapy and rehabilitation unit, 20 sessions in total, 5 days a week, and 30 minutes each session. will be applied. Patients will be treated in the form of daily arrival and departure. Vagus nerve stimulation will be performed using a TENS device with specially designed ear-shaped surface electrodes, the size of which can be selected according to any size ear. The electrodes will be placed on the inner and outer surface of the tragus and the concha. Waveform biphasic asymmetrical, pulse duration less than 500 microseconds and frequency of 10 hertz for 30 minutes. been applied continuously throughout and the amplitude will be adjusted according to the sensory threshold level.

Device: vagus nerve stimulation

exercise-vagus stimulation group

EXPERIMENTAL

Exercise and vagus stimulation treatment group; Both the applications made to the patients in the vagus stimulation group and the same exercises given to the patients in the exercise therapy group will be given as a home program. Patients in all groups will be evaluated with different parameters twice, before and after the treatment.

Device: vagus nerve stimulation

Interventions

vagus nerve stimulation DEVICE

Vagus stimulation, TENS device with specially designed and shaped surfaces that can be shaped according to the magnifying ear will be performed. The electrodes will be placed in such a way that the tragus is facing the inner and outer world. The wave formula is biphasic asymmetrical, pulses less than 500 microseconds and 10 hertz for 30 minutes. will be custom-made and the amplitude will be set as the sensory threshold.

Also known as: exercise therapy group, exercise-vagus stimulation group

exercise therapy group; exercise-vagus stimulation group; vagus stimulation group
