Participants in the control group will continue their usual care, which includes conventional physical and occupational therapy, for a duration of two weeks. They will follow their regular therapy schedules without any changes to their routines or treatment habits. This approach ensures that the control group reflects standard rehabilitation practices, allowing for a direct comparison with the intervention group.

Assessment of passive and active range of motion for targeted joints using the Biodex System 4 Pro® dynamometer (Biodex Medical Systems, Inc., Shirley, NY, USA).

Evaluation of muscles co-contraction in lower limbs and upper limbs by combining isometric force measurements with electromyography (EMG) recordings to monitor the activation patterns of agonist and antagonist muscles during contractions.

Measurement of gross manual dexterity by counting how many blocks a participant can transfer from one side of a box to the other in one minute

Measurement of the maximum distance covered by the patient in a 2-minutes' walk test, assessing the endurance and walking ability over a short duration.

Evaluation of spinal function through electromyography (EMG) during the 2-minutes' walk test, assessing muscle activation and coordination of the spinal cord during walking

Measurement of sensory response to determine pain threshold and pain perception.

Ecological assessment of daily pain perception using a smartphone application sending randomized notifications throughout the day to prompt the patient to report their pain levels.

Questionnaire assessing the severity of pain and its impact on functioning.

Questionnaire designed to identify patients likely experiencing neuropathic pain and to assess its severity.

Questionnaire assessing the extent of catastrophic thinking related to pain, including rumination, magnification, and helplessness, across three subscales. The total score ranges from 0 to 52 (higher scores indicate a greater degree of pain catastrophizing).

Questionnaire assessing five cognitive coping strategies for managing pain-distraction (attention diversion), catastrophising, praying and hoping, ignoring pain sensations, and reinterpreting pain sensations-based on the frequency of use for each strategy.

Questionnaire assessing the belief in one's ability to handle various difficult situations. Scores range from 10 to 40 (lower scores suggest reduced self-efficacy).

The COPM measures the patient's self-perception of occupational performance and satisfaction of it in daily activities over time. It ranges from 1 to 10, a higher score means a better performance.

Questionnaire assessing the patient's performance in unimanual and bimanual upper limb activities, with scores ranging from -6 to +6 logits (higher score indicates better performance).

Questionnaire assessing the patient's ability to perform daily activities using the upper and/or lower limbs, with scores ranging from -5 to +5 logits (higher scores indicates better performance).

Questionnaire assessing the patient's ability to perform daily activities using the lower limbs, with scores ranging from -4 to +4 logits (higher scores indicates better performance)

Questionnaire assessing the participation and engagement in life situation, assessing how cerebral palsy affects the patient's ability to participate in various activities and social situations.

Questionnaire assessing the patient's level of anxiety and depression, with scores ranging from 0 to 21 for both subscales (higher scores indicate higher levels of anxiety of depression).

Questionnaire assessing the impact of pain on sleep quality. Scores range from 0 to 30 (higher scores indicate greater disruption to sleep due to pain).

Questionnaire assessing fatigue across five dimensions: general fatigue, physical fatigue, mental fatigue, reduced activity, and reduced motivation. Each subscale score ranges from 4 to 20 (higher scores indicate more severe fatigue in the respective domain).

Questionnaire assessing quality of life across four domains: physical health, psychological health, social relationships, and environment. Scores for each domain range from 4 to 20 (higher scores indicate better quality of life).

Questionnaire assessing perceived cognitive function, focusing on areas such as memory, attention, and problem-solving. It is a 4-item questionnaire, each item uses a 5-point Likert scale ranging from 1 ("Never") to 5 ("Always"), with higher scores indicating worse cognitive functioning.
