Participants in the experimental group received a 2-week intensive physiotherapy program based on Neurodevelopmental Treatment (NDT) principles with active participation.

Frequency: 6 days per week Sessions: 2 sessions per day Session duration: 50 minutes Total sessions: 24

Intervention components included:

• Weight-shifting and reaching activities in crawling, sitting, kneeling, and standing positions
• Functional and symmetrical reaching tasks in different postures
• Actively assisted transitions between postures
• Balance training and facilitation of protective reactions in various positions
• Core stabilization exercises
• Isolated strengthening exercises for upper and lower extremities
• Proprioceptive training exercises

Participants in the control group received a 2-week conventional physiotherapy program.

Frequency: 3 days per week Sessions: 1 session per day Session duration: 45 minutes Total sessions: 6

Intervention components included:

• Stretching and strengthening exercises
• Passive and active range of motion exercises
• Balance and coordination exercises in different positions
• Electrotherapy applications

Seated Postural Control Measure (SPCM) evaluates static, active, and reactive trunk control at different trunk segments in a supported sitting position. It identifies the highest trunk level at which independent postural control is achieved in children with cerebral palsy. SPCM consists of three sub scales. In this study only function subscale will be used. The Function subscale of the Seated Postural Control Measure consists of 12 items evaluating head and trunk control during sitting, reaching, grasping and releasing, bimanual use, and wheelchair mobility. Each item is scored on a 4-point ordinal scale ranging from 1 to 4 points, with higher scores indicating better task performance. The total score of the Function subscale ranges from a minimum of 12 points to a maximum of 48 points.

The Selective Control of the Upper Extremity Scale (SCUES) selective voluntary motor control of the shoulder, elbow, forearm, wrist, and fingers during functional tasks in children with cerebral palsy. Higher scores indicate better selective motor control of the upper extremities.Selective motor control (SMC) is graded for each joint using a four-point ordinal scale: 3 points indicate normal selective motor control, 2 points- mildly impaired SMC, 1 point-moderately impaired SMC, 0 points- absence of SMC. For each upper extremity maximum point is 15.

The Selective Control Assessment of the Lower Extremity (SCALE) evaluates the ability to perform isolated voluntary movements at the hip, knee, ankle, subtalar joint, and toes independently of mass synergistic patterns in children with cerebral palsy.Higher scores indicate better SMC of the lower extremities.2 points- normal SMC, 1point impaired SMC, and 0 points unable to perform. For each lower extremity maximum point is 10.

The Gross Motor Function Measure-88 (GMFM-88) evaluates changes in gross motor function, including lying and rolling, sitting, crawling and kneeling, standing, and walking, running, and jumping in children with cerebral palsy. The Gross Motor Function Measure-88 consists of 88 items and is administered through observation of motor performance by a physiotherapist in children with cerebral palsy.

Each item is scored on a 4-point ordinal scale as follows:

0 - Does not initiate the movement,

1. - Initiates the movement (<10% of the task),
2. - Partially completes the movement (10-90% of the task),
3. - Completes the movement independently. Scores for each dimension are calculated as percentages. The total GMFM-88 score is obtained by averaging the five dimension percentage scores (0-100). Higher percentage scores indicate better gross motor function.
