This is an intervention study including a baseline data collection, 6 weeks of robot-assisted training targeting hand dexterity, and a post-intervention data collection. The study will be conducted in the Motion Analysis Laboratory at Spaulding Rehabilitation Hospital, Boston, MA. This study aims to assess the effectiveness of a robot-assisted training on hand dexterity and quality of life in children with cerebral palsy. Additionally, the investigators will study the relationship between muscle synergies and the outcomes of robot-assisted training.
Participants will be assessed 2 times - before and after training with the robot. All the testing and training will be done at Spaulding Rehabilitation Hospital and will include:
Clinical tests:
Muscle activity tests:
• A test to get detailed measures of how well participant can perform movements. The measures collected will include the movements of fingers, hands, and arms while picking up different objects. Movements will be tracked by attaching small reflective markers to the fingers, hands, and arms of the participant. Special cameras will be used to collect data. Special sensors (called electromyographic - EMG - sensors) will be attached to the hands and arms to tell the investigators when and how muscles are recruited to generate the movements.
Training with the Robot:
Study participants will undergo robot-assisted training for 18 times - up to 4 times per week during a period of approximately 7 weeks. The training sessions will be carried out by trained study staff. The robot will assist study participants to perform the movements while they attempt to move their fingers to control computer games. The assistance provided by the robot will be adjusted to the ability of each participant to move their hand. Each training session will last about 1 hour. This will include about 20 minutes of stretching exercises, setup time, and warm-up exercises. Study participants will be encouraged to ask for rest breaks whenever needed. The investigators will closely monitor study participants during all study sessions.

| Change in Box and Block Test Score | Gross manual dexterity assessment. The test is administered by using a wooden box divided in two compartments. At the beginning of the test, 150 wooden blocks are positioned in one of these compartments. Then study participants are instructed to move, one by one, the maximum number of wooden blocks from one compartment to the other one in a time interval of 1 minute. The result of the test is the number of wooden blocks moved in 1 minute.

| Data collected at baseline and at completion of the 7-week intervention |
| Change in Cerebral Palsy Quality of Life Questionnaire Score - Child | Questionnaire for evaluation of quality of life as reported by the child. The questionnaire covers different domains (e.g. social wellbeing and acceptance). Data is reported on a scale from 0 to 100. The change from baseline to post-intervention is calculated by taking the difference between the value gathered pre-intervention and the value gathered post-intervention. The change from baseline to follow-up is calculated by taking the difference between the value gathered pre-intervention and the value gathered at one month follow-up. | Data collected at baseline, at completion of the 7-week intervention, and at one month follow-up |
| Change in Number of Muscle Synergies | Subjects will be asked to reach and grasp objects of different sizes and shapes. Surface electromyographic (EMG) activity will be collected from 16 muscles of the upper-limb. EMG data is then analyzed using a mathematical technique (referred to as non-negative matrix factorization) that allows researchers to quantify patterns of co-activation among muscles. The number of muscle synergies necessary to accurately reconstruct the individual EMG channel recordings will be herein considered. | Data collected at baseline and at completion of the 7-week intervention |
| Change in Modified Ashworth Scale Score | Upper extremity muscle spasticity assessment. This scale is administered by manually moving the subject's body segments and evaluate if an involuntary (reflex) response of muscles interfere with the passive movement. If testing a muscle that primarily flexes a joint, the rehabilitation specialist evaluating the subject places the joint in a maximally flexed position and moves it to a position of maximal extension over one second. If testing a muscle that primarily extends a joint, the rehabilitation specialist evaluating the subject places the joint in a maximally extended position and moves to a position of maximal flexion over one second. Spasticity causes a contraction resisting the movement. The strength of the contraction (i.e. force involuntarily generated by muscles) is evaluated on a scale from 0 to 4. The change from baseline to post-intervention is calculated by taking the difference between the value gathered pre-intervention and the value gathered post-intervention. | Data collected at baseline and at completion of the 7-week intervention |
| Change in Cerebral Palsy Quality of Life Questionnaire Score - Caregiver | Questionnaire for evaluation of quality of life as reported by the caregiver. The questionnaire covers different domains (e.g. social wellbeing and acceptance). Data is reported on a scale from 0 to 100. The change from baseline to post-intervention is calculated by taking the difference between the value gathered pre-intervention and the value gathered post-intervention. The change from baseline to follow-up is calculated by taking the difference between the value gathered pre-intervention and the value gathered at one month follow-up. | Data collected at baseline, at completion of the 7-week intervention, and at one month follow-up |
| Synergy Similarity | Subjects will be asked to reach and grasp objects of different sizes and shapes. Surface electromyographic (EMG) activity will be collected from 16 muscles of the upper-limb. EMG data is then analyzed using a mathematical technique (referred to as non-negative matrix factorization) that allows researchers to quantify patterns of co-activation among muscles. The similarity among muscle synergies is estimated by computing the scalar product between corresponding muscle synergies. Results are reported individually for each muscle synergy. The minimum scalar product is 0 and it means that the synergies (pre- vs post-interventions) are highly dissimilar. The maximum scalar product is 1 and it means that the synergies (pre- vs post-interventions) are identical. | Data collected at baseline and at completion of the 7-week intervention |
