Clinical Trial Summary

This study will be conducted in Hacettepe University Faculty of Medicine Neurosurgery Department and Hacettepe University Faculty of Physical Therapy and Rehabilitation.

The study was designed as a randomized controlled trial. At the beginning of the study, demographic data and characteristics of the cases will be recorded. Patients will be evaluated in three different periods throughout the study. The first assessments will be performed on the first day after the patient's condition is appropriate after the surgical procedure for Type 1 CM. Following this evaluation, all patients will be divided into two groups using. a simple randomization method. The first group will be exercised for 6 weeks while the second group will not be intervened during this period and will be followed as a control group. Immediately after the exercise program administered to the first group after 6 weeks, both groups will undergo second assessments. After these assessment measures, the same exercise program in the first group will be applied to the second group only this time for 6 weeks. In the meantime, the first group will stop their exercise programs. After the 6-week exercise program of the second group has ended, both groups will be given the third assessment, the final assessment.

At the beginning of the study, demographic data, characteristics and disease information will be recorded.

The evaluations to be made are summarized below:

• Visual Analogue Scale, pain threshold and pain tolerance tests, Neck Disability Index, for the determination of pain level in the neck region and throughout the body

• Cervical range of motion (Performance Attainment Associates, St. Paul, MN, 55117, United States) (CROM 3) device for the evaluation of the cervical region.

• Berg Balance Scale for evaluation of performance-based balance,

• Timed Rise Walk Test, Sharpened Romberg test and "8" shaped walk test (F8WT) for evaluation of fall risk, static and dynamic balance,

• The International Ataxia Assessment Scale (ICARS) for coordination,

• Grip Ability Test (GAT) for the assessment of fine motor skill in the upper extremity,

• Posture evaluation,

• Eating Assessment Tool (EAT-10) for evaluation of swallowing function

• For daily living activities, Barthel Daily Living Activities Index,

• For the quality of life, the Short Form 36 questionnaire will be used.

This study will be conducted in Hacettepe University Faculty of Medicine Neurosurgery Department and Hacettepe University Faculty of Physical Therapy and Rehabilitation.

The study was designed as a randomized controlled trial. At the beginning of the study, demographic data and characteristics of the cases will be recorded. Patients will be evaluated in three different periods throughout the study. The first assessments will be performed on the first day after the patient's condition is appropriate after the surgical procedure for Type 1 CM. Following this evaluation, all patients will be divided into two groups using. a simple randomization method. The first group will be exercised for 6 weeks while the second group will not be intervened during this period and will be followed as a control group. Immediately after the exercise program administered to the first group after 6 weeks, both groups will undergo second assessments. After these assessment measures, the same exercise program in the first group will be applied to the second group only this time for 6 weeks. In the meantime, the first group will stop their exercise programs. After the 6-week exercise program of the second group has ended, both groups will be given the third assessment, the final assessment.

"The study will be conducted in individuals aged 18-65 years who have been diagnosed with Type 1 CM by the physician and have been decided to undergo surgery for this diagnosis. In our study whose primary outcome parameters were determined as "Neck Disability Index" and "Visual Analogue Scale minimum, the minimum sample width required to reach 95% -99% power was six individuals in total. For various reasons (patient withdrawal, etc.), the rate of withdrawal from the study was predicted to be 25%. Accordingly, the study was decided to be conducted with a total of eight individuals.

Patients with a history of primary neurological disease other than Chiari Type 1 Malformation, severe cognitive impairment (> 24 from Mini-Mental State Assessment), peripheral vestibular problem, and history of orthopedic surgery will not be included in the study.

The data will be evaluated using SPSS for Windows 22.00. Descriptive statistics will be presented as a minimum, average, median, standard deviation, maximum and categorical variables for numerical variables and as percentages. The suitability of the variables to normal distribution will be examined by the Shapiro-Wilk normality test. Whether the groups (Group 1, Group 2) are similar in terms of gender will be examined by the Pearson Chi-Square Test when the prerequisites are met, and Fisher's exact test if not. By the cross-pass research design, the block, period, trial and sequence effects will be analyzed with a mixed effect model.

At the beginning of the study, demographic data, characteristics and disease information will be recorded.

The evaluations to be made are summarized below:

• Visual Analogue Scale, pain threshold and pain tolerance tests, Neck Disability Index, for the determination of pain level in the neck region and throughout the body

• Cervical range of motion (Performance Attainment Associates, St. Paul, MN, 55117, United States) (CROM 3) device for the evaluation of the cervical region.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Visual Analog Scale	Visual analogue scales (VAS) of sensory intensity and affective magnitude were validated as ratio scale measures for both chronic and experimental pain.	VAS was used to assess changes in chronic and experimental pain of individuals at 6th and 12th week of exercise intervention.
Primary	Neck Disability Index	The Neck Pain Disability Index (NDI) is a questionnaire that is commonly used in clinical trials to measure the functional status of patients with neck pain. The NDI was originally developed for assessing the functional status of patients with disabling neck pain, particularly whiplash-associated disorders. The NDI consists of 10 items addressing functional activities, such as personal care, lifting, reading, work, driving or cycling, sleeping and recreational activities, and a number of symptoms such as pain intensity, concentration, and headache.For each item, answering options range from 0 = no disability to 5 = total disability, resulting in a total range of scores from 0 to 50 points.	NDI was used to assess changes in functional status of patients with neck pain at 6th and 12th week of exercise intervention.
Secondary	Berg Balance Scale	The Berg balance scale (BBS) assesses functional balance performance based on 14 items common to daily life. The maximum score that can be reached is 56 and each item possesses an ordinal scale of five alternatives ranging from 0 to 4 points.	BBS was used to assess changes in functional balance performance at 6th and 12th week of exercise intervention.
Secondary	Sharpened Romberg Test	The subjects were instructed to stand barefoot with the dominant foot just in front of the other (tandem stand, i.e., heel to toe), arms folded across the chest, with eyes open in the first trial, and with eyes closed in a second trial. The score was the number of seconds the subject maintained the test position. Timing started when the subject assumed the proper position and indicated she was ready. Timing stopped if the subject moved either foot from the proper position, opened her eyes in the eyes closed trial, or reached the 60 second time limit.	Sharpened Romberg Test was used to assess changes in functional balance performance at 6th and 12th week of exercise intervention.
Secondary	Short Form 36	The SF36 is a short questionnaire with 36 items which measure eight multi-item variables: physical functioning (10 items), social functioning (two items), role limitations due to physical problems (four items), role limitations due to emotional problems (three items), mental health (five items), energy and vitality (four items), pain (two items), and general perception of health (five items).	Short Form 36 was used to assess changes in quality of life at 6th and 12th week of exercise intervention.
Secondary	Barthel Daily Living Activity Index	Barthel Index of Activities of Daily Living. The Barthel Index (BI) is one of the most widely used rating scales for the measurement of activity limitations in patients with neuromuscular and musculoskeletal conditions in an inpatient rehabilitation setting.	Short Form 36 was used to assess changes in daily living activities at 6th and 12th week of exercise intervention.
