Cerebral palsy (CP) affects the motor function but also the cognitive function of the child. Physical activity brings motor and cognitive benefits and appears as an important aspect of the therapy that is offered to them.
The child is seating in front of a computer, seating comfortably on a chair during 1 hour. The experimental task consists in learning a sequence of taps on "Serial reaction time task" type buzzers (SRTT) in which the child must press a buzzer corresponding to one of the 4 squares that on the screen. The sequence corresponds to 10 steps in a particular order.
Cerebral palsy (CP) affects the motor function but also the cognitive function of the child. Physical activity brings motor and cognitive benefits and appears as an important aspect of the therapy that is offered to them. In particular, the learning of movements in the presence of multisensory rhythmic information seems to have beneficial effects at the cognitive and motor level. The present study aims to test the respective effects of rhythm and multisensoriality on motor learning in children with cerebral palsy.
The motor learning task is known as the "Serial Reaction Time Task" (SRTT). It consists in repeating a sequence of movements of the upper limbs using visual-spatial information alone (V). It will test the addition of synchronous auditory stimulation to visual information or rhythmic auditory stimulation(VAR), to contrast with a control condition with non-rhythmic auditory stimulation (VANR). The performance of the children will be measured by the reaction time (RT), its stability and the number of errors made throughout the motor learning.
The child is placed in front of a screen on which 4 luminous stimuli are presented on a horizontal plane. Four buzzers are placed in front of him, each buzzer corresponds to the position of a stimulus. The stimuli light up in a predetermined sequence (10 positions) and the child must press the buzzer corresponding to the position of the stimulus that comes on. Four blocks of 5 sequences are repeated to test the general learning (B1 to B4) and then a block of random stimuli is presented to test the specific learning of the sequence (B5).
For all children:
For children with Cerebral Palsy:
For control children: no pathology diagnosed
Exclusion Criteria:
For all children:
Serial reaction time task: repeating a sequence of movements according to the luminous stimuli
Other: luminous stimuli
Serial reaction time task: of movements according to the luminous stimuli
Other: luminous stimuli
The child is placed in front of a screen on which 4 luminous stimuli are presented on a horizontal plane. Four buzzers are placed in front of him, each buzzer corresponds to the position of a stimulus. Child had to push the buzzer corresponding to the place of the luminous stimuli.
Also known as: Serial reaction time task
Time reaction (TR)
- The TR is the Reaction Time between the appearance of the stimulus and the response. It represents the speed with which the child pressed the key in response to the lighting of the square.
Time frame: 1 hour
Number of errors
The number of errors corresponds to pressing a key that does not correspond to the position of the lit square.
Time frame: 1 hour
Multisensory integration degree
Multisensory integration degree evaluated in pre-test
Time frame: 1 hour
Degree of synchronization
Degree of synchronization evaluated in pre-test
Time frame: 1 hour
