About this study

This project will develop the first sensor-based mobile Pelvic Assist Device (mPAD) that can deliver precise, adaptable, pelvic control to restore natural coordination of upper- and lower-limb movements during gait in children with Cerebral Palsy

Read the detailed description

Gait impairments hinder mobility for more than 760,000 children and adults living with cerebral palsy (CP) in the US. Motor relearning is possible for these individual but typically requires numerous training sessions with a team of physical therapists and assistants to restore coupling between upper- and lower-body segments while assisting spastic uncoordinated limb movement to improve gait kinematics. This clinical trial will meet the overall objective of testing the feasibility of developing a smart-robotic exoskeleton that is effective at providing guided pelvic assistance and support while biofeedback mediated training is facilitated under the supervision of a physiotherapist. The project will test a novel tethered Pelvic Assist Device (TPAD) with integratable electromyographic (EMG) and inertial (IMU) biofeedback that is uniquely capable of delivering precise, adaptable, multi-degree-of-freedom pelvic control to promote natural intersegmental coupling, restore coordination of upper- and lower-limb movement, and improve normal gait kinematics in children with CP. Because of its proximity to the center of mass and critical role in coordinating upper- and lower-limb control, the pelvis provides an ideal access point for physiotherapists to manually improve gait. The investigators will test the hypothesis that accurate sensor-based metrics of gait can be derived from EMG and IMU wearable sensors to develop a biofeedback system for motor learning that are integratable with TPAD to develop a new mobile mPAD device that is compliant with the target population.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Gait Metric Accuracy

    Measures the accuracy of identifying heel strike and toe off timing in % error when comparing measures from wearable sensors vs. motion capture

    Measured: 1 day

  2. Pelvis Range of Motion During Walking

    Difference (in degrees) between pelvis range of motion during walking as detected by wearable sensors and motion capture

    Measured: 1 day

  3. Muscle Activation During Walking

    Measures electromyographic (EMG) signals of trunk and lower limb muscles during gait which are necessary for designing and implementing a mobile pelvic assist device (mPAD) system with biofeedback

    Measured: 1 day

  4. Rating of Perceived Difficulty

    Structured interviews will be used to grade the perception of difficulty in using the technology

    Measured: 1 day

  5. Trunk Range of Motion During Walking

    Difference (in degrees) between trunk range of motion during walking as detected by wearable sensors and motion capture

    Measured: 1 day

  6. Hip Range of Motion During Walking

    Difference (in degrees) between hip range of motion during walking as detected by wearable sensors and motion capture

    Measured: 1 day

  7. Knee Range of Motion During Walking

    Difference (in degrees) between knee range of motion during walking as detected by wearable sensors and motion capture

    Measured: 1 day

Questions about this trial

What is this clinical trial studying?

A study testing mPAD (or TPAD) Pelvic Assist Device in people with Cerebral Palsy and Gait Disorders, Neurologic, run by Altec Inc. at 2 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 15 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 4 Mar 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 10 Nov 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Gait Metric Accuracy (time frame: 1 day). The study lists 7 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Mar 2022.
