Classical physiotherapy program will be applied for gross motor functions and upper extremity functions.

In addition to the classical physiotherapy program for gross motor functions, will be applied in the Neuro-Creative Music Therapy (NCMT) program for upper extremity.

The session is 50 minutes long and consists of 20 minutes of classical physiotherapy for gross motor functions and 30 minutes of classical physiotherapy for the upper extremity. A total of 16 sessions will be applied 2 days a week for 8 weeks.

Children's Hand-Use Experience Questionnaire (CHEQ) is a scale that evaluates unilateral hand disorders in children due to various reasons (such as hemiparetic CP, brachial plexus or upper extremity developmental deficiency for any reason). CHEQ consists of 27 sub-items and evaluates quality aspects of movement in three different subscales, including the grasping efficiency of hand functions, the time required to perform the activity, and the feeling of discomfort caused by the affected hand during the performance of the activity.

Abilhand-Kids scale evaluates hand functions in children with CP. It measures the use of the upper extremity during children's daily activities in 21 items. There are 3 points in the scoring: 0: cannot be done, 1: difficult, 2: easy.

Selective Control of the Upper Extremity Scale (SCUES) is a measurement tool specifically designed for this area, developed to evaluate selective motor control of the upper extremity. It is a useful evaluation measure that is video-based and implemented in less than 15 minutes. The degree of selective motor control is determined for each joint as "normal selective motor control: 3 points, mildly reduced selective motor control: 2 points, moderately reduced selective motor control: 1 point, no selective motor control: 0 points".

Pediatric Quality of Life Inventory (PedsQL) 3.0 Cerebral Palsy (CP) Module was developed to evaluate CP-specific quality of life areas of children with CP between the ages of 2-18. The scale questions the degree of problems experienced by individuals in the last month. The 35-item module consists of seven subscales: daily activities (9 items), school activities (4 items), movement and balance (5 items), pain and suffering (4 items), fatigue (4 items), eating activities (5 items), speech and communication (4 items). Subscale scores are calculated by dividing the total score of the answered items by the number of answered items. A higher mean score on a subscale of a field indicates that there are fewer problems in that field and the quality of life is higher.

Semmes Weinstein Monofilament Test (SWMT) is a tactile test battery recommended to evaluate tactile sensation in individuals with CP. The SWMT battery has five different thicknesses of monofilament ranging from 2.83 to 6.65. The evaluation starts with the thinnest (2.83) filament and continues until the monofilament that the individual begins to feel.

The Gross Motor Function Classification System (GMFCS) determines the level most appropriate to an individual's limitations and skills in gross motor functions. This classification measures the individual's self-initiated movements based on displacement, sitting and mobility, regardless of the individual's motor disorder type. As a result of the findings, individuals are divided into 5 levels according to their motor function levels. Individuals at Level 1 have minimal motor limitations.
