Functional and Neuroplastic Effects of HABIT-ILE in Children With Bilateral Cerebral Palsy

The Both Hands Assessment is a valid test for children with mild to moderate bilateral manual abilities impairments. It can evaluate bimanual activity performance and the level of upper extremity asymmetry. It rates performance between 1 (does not do) and 4 (effective). The final score is converted to BoHA units (logit 0 - 100), where higher scores reflect better bimanual use.

The Melbourne 2 Assessment (MA2) assesses the unilateral performance of the upper extremities, quantifying the dexterity, fluency, accuracy, and range of movement during several tasks of reaching and manipulation. The result is obtained as a percentage of the function of each item. A higher percentage means a better unilateral performance of the upper extremity.

The TASC test assesses the selective voluntary motor control of upper limbs in individuals with cerebral palsy. The participant must execute eight movements in the upper extremity. The execution of each sequence will be assessed on a scale of 0, 1, or 2, from absence, impairment, or normality of voluntary selective motor control, respectively, with a maximum of 16 points per side and 32 points overall.

The SCALE test assesses the selective voluntary motor control of lower limbs in individuals with cerebral palsy. The participant must execute five movements in the lower extremity. The execution of each sequence will be assessed on a scale of 0, 1 or 2, from absence, impairment, or normality of voluntary selective motor control respectively, with a maximum of 10 points per side and 20 points overall.

The 6MWT measures the maximum distance a participant can walk in a 6-minute period in a 30-meter corridor at his or her own pace. More distance walked (in meters) indicates better performance.

The ANT assesses the efficiency of the three attentional networks: alerting, orienting, and executive control networks. It measures the accuracy (in terms of the amount of errors) and the reaction time (milliseconds) of each network. Fewer errors mean more accuracy, the lower the score, the faster the reaction time.

This parent's filled questionnaire measures the ability of the participant with cerebral palsy to perform activities of daily living that require the use of the upper extremities. The difficulty to perform the activities are rating as "Impossible", "Difficult" or "Easy". The result is obtained in logits and can be interpreted as a percentage, where 0% indicates minimum ability and 100% maximum ability to perform the activities.

This parent's filled questionnaire measures a child performance of daily activities requiring the use of the upper and/or the lower extremities through 43 items specific to patients with cerebral palsy. It ranges from - 7 to +7 logits (higher score means better performance). The result is obtained in logits and can be interpreted as a percentage, where 0% indicates minimum ability and 100% maximum ability to perform the activities.

This parent's filled questionnaire measures the performance of the child in the daily life activities and movement domains, focusing on the capacity of upper extremities and lower extremities during these activities. It ranges from 20 to 80 (higher score means better performance).

This parent's filled questionnaire measures participation of children and youth with or without disability, in the home, school and community, along with environmental factors within each of these settings. For each environment, it assesses how frequently they participate in a given activity (8-point scale; 0-7), how involved they are in that activity (5-point scale; 1-5), and whether they want to make a change in the type of participation they perform (6-point scale; 1-6). For each setting, the participation frequency (percentage), involvement (score 1-5), desires for change (percentage), and environmental supportiveness (percentage) are calculated.

This is an interview-setting designed to capture a patient's self-perception of performance and satisfaction of it in everyday activities, observed over time. During the interview, parents set up 5 activities considered difficult in daily life. These are then assessed, in a 1 to 10 scale, regarding the child's self-perception of performance and satisfaction of it. The total score is the average of the scores for perception and satisfaction separately (score from 1 to 10; higher score means better performance/satisfaction).

The BRIEF-2 is a caregiver-reported questionnaire measuring executive functioning in children between 5 and 18 years old. It consists of 63 items arranged in nine scales: inhibition, self-monitoring, flexibility, emotional control, initiative, working memory, planning and organization, task supervision, and organization of materials. It is scored using T scores (Range= 34 - 90; Mean=50, Standard Deviation=10), where higher scores indicate greater problems with executive functioning.

A single-pulse transcranial magnetic stimulation is a noninvasive technique that directly assesses cortical function and connectivity in the motor system. It will be used to assess the corticospinal tract excitability in both brain hemispheres. It will stimulate the primary motor cortex with a figure-8 coil, searching for the first dorsal interosseous muscle area. The changes of peak-to-peak amplitude of motor evoked potential will be measured in milliAmpere (mA).

The changes of latency in motor evoked potential will be measured in milliseconds.

A functional near-infrared spectroscopy will be used to assess cortical activity. It is a noninvasive brain imaging tool that records optical density measurements to determine the change in oxyhemoglobin concentration (μM) in sensorimotor cortex area during manual tasks.
