Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Motor learning involves acquiring new skills to improve movement quality. While typically developing children learn motor activities naturally, children with CP may experience difficulties due to structural and motor planning deficits. Motor imagery (MI), defined as mentally simulating a movement without physical execution, is one strategy that supports motor learning. MI and actual movement engage similar brain regions and share cognitive and neurophysiological components.
MI can be experienced from a visual or kinesthetic perspective. Visual imagery involves watching the movement as an observer, while kinesthetic imagery involves internally experiencing the movement as the actor. Kinesthetic imagery is more closely associated with motor planning and functional improvement. MI can be explicit, involving conscious simulation of movement, or implicit, occurring unconsciously through internal body representations. Both forms are used in neurorehabilitation.
Previous studies on MI in children with CP have typically included participants aged 6 to 20 with relatively good motor and functional abilities. Although some researchers suggest that MI skills begin to develop between the ages of 5 and 7, findings are inconsistent, highlighting the need for further investigation.
Research exploring factors that may influence MI ability in children with CP is limited. While age has been studied to a small extent, the effects of sex, clinical type, body mass index (BMI), Gross Motor Function Classification System (GMFCS) level, and Manual Ability Classification System (MACS) level have not been thoroughly examined. This study aims to explore the influence of these variables on MI ability in children with CP. After recording the children's demographic characteristics (age, sex, height, weight, body mass index \[BMI\], and duration of physiotherapy), the following assessments will be conducted:
Gross Motor Function Classification System (GMFCS):
GMFCS is a five-level classification system used to assess gross motor function in individuals with CP, focusing on sitting, transfers, and mobility. It categorizes function based on self-initiated movement across specific age bands: 0-2, 2-4, 4-6, 6-12, and 12-18 years. Level I indicates independent walking with minimal limitations, while Level V indicates the need for a wheelchair for mobility.
Manual Ability Classification System (MACS):
MACS is used to classify how children with CP (aged 4-18 years) use their hands to handle objects in daily life. Level I indicates the highest manual ability, with ease in handling objects, while Level V indicates very limited ability and the need for maximum assistance.
Hand Laterality Task:
Implicit motor imagery ability will be assessed using the Hand Laterality Task, which requires participants to identify whether an image shows a left or right hand. The Recognise Hand app, developed by the NOI group, will be used for this purpose. Outcome measures include response accuracy (percentage of correct responses) and reaction time.
Mental Chronometry Task:
Explicit motor imagery will be assessed using the mental chronometry paradigm. Participants will first perform a physical movement and then imagine performing the same movement toward targets at varying distances. The duration of the actual and imagined movements will be recorded. The Box and Block Test will be used, and temporal congruence will be calculated using the delta time formula: \[(actual movement time - imagined movement time) / ((actual movement time + imagined movement time) / 2)\] x 100.
Box and Block Test:
This test evaluates manual dexterity and is commonly used in both clinical and research settings due to its simplicity and cost-effectiveness. Participants are instructed to move as many blocks as possible from one compartment to another in 60 seconds. The score reflects the number of successfully transferred blocks, with higher scores indicating better upper extremity performance. It will also be used in the mental chronometry task.
Movement Imagery Questionnaire for Children:
This questionnaire evaluates visual (internal, external) and kinesthetic imagery abilities. It includes 12 items: 4 for each imagery type. Participants will perform four movements physically and then imagine them from each perspective. Imagery vividness will be rated on a 7-point Likert scale (1 = very hard to feel, 7 = very easy to feel). Higher scores indicate better imagery ability.

Unilateral cerebral palsy
Cerebral Palsy (CP) is a group of permanent disorders in activity limitation, motor and posture development due to non-progressive damage to the developing fetus or infant brain. In spastic unilateral CP, involvement occurs unilaterally in one half of the body.
Implicit motor imagery
Implicit motor imagery is the ability to engage with the projection and manipulation of the body schema from a first-person perspective. Implicit motor imagery skills were evaluated Recognize App Recognize Hand Hand Laterality Task with, developed by NOI group. (http://www.noigroup.com/ Recognise).
Explicit motor imagery
In explicit motor imagery, the person simulates a specific motor movement, that is, the individual is aware that she is imagining the movement.Explicit motor imagery skills were evaluated with Movement Imagery Questionnaire for Children (MIQ-C), mental chronometry and box block test.
Bilateral cerebral palsy
Cerebral Palsy (CP) is a group of permanent disorders in activity limitation, motor and posture development due to non-progressive damage to the developing fetus or infant brain. In spastic bilateral CP, involvement is seen bilaterally in all 4 extremities.
