Robotic TruST-Postural Intervention for Children With Cerebral Palsy

December 21, 2023 updated by: Teachers College, Columbia University

Postural Control Intervention With the Robotic Trunk-Support-Trainer (TruST) in Children With Cerebral Palsy: A Randomized Controlled Trial

The purpose of this study is to test the efficacy of a motor learning-based postural and reaching control intervention delivered with the robotic Trunk-Support-Trainer (TruST) compared to the same motor learning-based intervention delivered with Static Trunk Support Equipment in children with cerebral palsy (CP) classified as III and IV with the Gross Motor Function Classification System (GMFCS).

Detailed Description

This study is a prospective Clinical Randomized Control Trial (RCT) in a group of 82 children with cerebral palsy. The experimental and control groups will receive effective postural-reaching training based on motor learning and control principles. In both groups, participants will engage in play and functional activities that elicit arm movement and challenge trunk postural control, and the motor tasks and activities will be progressed. The main difference is that the experimental group will be trained with TruST in order to add postural task-progression via assistive force fields; which will be tailored to the child's sitting control balance status across training sessions. However, in the control group, postural task-progression will be addressed by lowering the level of rigid trunk support segment by segment across training sessions. The trunk subregion where the support is placed will depend on the child's trunk control ability. Participants will be recruited from the United States.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in Modified Functional Reach Test (mFRT) after intervention
Time Frame: Through study completion, an average of 4 months
The mFRT measures proactive postural control during maximum reaching distance. It is a valid and reliable tool in CP; and it discriminates GMFCS levels.
Through study completion, an average of 4 months
Change in Postural Star-Sitting Test (PSST) after intervention
Time Frame: Through study completion, an average of 4 months
The PSST will be performed before and after interventions to monitor sitting control progression in both TruST- and control-intervention groups. The investigators have several motivations that rationalize this customized measurement. It: 1) is age-appropriate, 2) is goal-oriented, 3) directly measures sitting based on trunk control improvements, 4) is responsive to capture sitting workspace area increases, and 5) offers data with a straightforward functional interpretation.
Through study completion, an average of 4 months
Change in Box and Blocks Test (BBT) after intervention
Time Frame: Through study completion, an average of 4 months
The BBT examines manual dexterity. The child moves the maximum number of blocks (2.5cm2), one at a time, between the compartments of a partitioned box within 60s. B&B is sensitive to post-intervention changes with the more- and less-affected hand. Arm displacement and grasping will be analyzed with Datavyu. An instruction manual has been created to standardize video-coding procedures and define the reaching variables. Grasping will be defined from the moment the hand contacts the block to the time this is lifted from the surface. Arm displacement will be defined from end of grasping to block release. Reaching performance will be the summation of grasping and arm displacement. Two coders will be used to determine video-coding reliability.
Through study completion, an average of 4 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in Gross Motor Function Measure-Item Set (GMFM-IS) after intervention
Time Frame: Through study completion, an average of 4 months
The GMFM-IS determines the gross motor function of children with CP-A: lying and rolling, B: sitting, C: crawling, D: standing and E: walking, running & jumping. It is an abbreviated and validated version of the GMFM-66. It includes an algorithm with three critical items to decide which one of four item sets is most appropriate to assess motor function and obtain a GMFM-66 score. GMFM has been shown to be valid, reliable, and responsive to change in CP. The minimum clinically important difference (MCID) is 0.8-1.6 for medium effect size and 1.3-2.6 for large effect size.
Through study completion, an average of 4 months
Change in Canadian Occupational Performance Measure (COPM) after intervention
Time Frame: Through study completion, an average of 4 months
The COPM will be used to investigate perceived parent- and child-based goals, and preferences that are specific to motor impediments in seated posture and reaching abilities that restrict participation. COPM can detect clinical important differences across time and above the MCID of 2 points.
Through study completion, an average of 4 months
Change in Participation and Environment Measure - Children and Youth (PEM-CY) after intervention
Time Frame: Through study completion, an average of 4 months
The PEM-CY is a valid and reliable tool to measure participation-home, school and community-including environmental factors. PEM-CY can capture post-intervention changes in each of its dimensions in children with physical disabilities.
Through study completion, an average of 4 months
Change in Seated Postural & Reaching Control (SP&R-co) after intervention
Time Frame: Through study completion, an average of 4 months
The theoretical framework, reliability, internal consistency, and construct validity of the SP&R-co has been validated in CP. It targets children with moderate-to-severe CP within a play-oriented framework. Similar to the SATCo, the SP&R-co follows a segment-by-segment approach to assess quantitatively sitting control across static, active, proactive (via bimanual and unimanual reaches), and reactive dimensions. Responsiveness has not been addressed, but the standard error measurement of each SP&R-co dimension are available.
Through study completion, an average of 4 months
Change in Postural and Reaching Kinematics after intervention
Time Frame: Through study completion, an average of 4 months
We will follow the seated postural framework validated in the SP&R-co to capture motor improvements in the next tasks: (1) Static Seated Task: Postural orientation and balance in sitting during 10s. (2) Active Seated Task: Simultaneous control of the trunk and head rotations when the child visually follows an object to the right and left at a 90° angle. (3) Proactive Seated Task: Sitting control via anticipatory and compensatory postural adjustments during direction-specific reaches straight and 45° to the right and left.
Through study completion, an average of 4 months
Change in Segmental Assessment of Trunk Control (SATCo) after intervention
Time Frame: Through study completion, an average of 4 months
The SATCo is a valid and reliable test in CP. The evaluator offers support at various trunk segments (shoulders, axillae, inferior angle of scapulae, on lower ribs, below lower ribs, and pelvis) to measure trunk control across 3 dimensions: static (during 5s), proactive (visually following an object), and reactive (postural responses to nudges). The score is from 1 (no head control) to 8 (full trunk control). Test responsiveness has not been established but studies show potential to identify trunk balance improvements in each of the tested trunk segments.
Through study completion, an average of 4 months
