Study Summary

This trial is testing whether a new algorithm and higher count of surface electromyographic electrodes can improve control of myoelectrically-controlled advanced orthotic devices.

Who is the study for?

This trial is for individuals who have had their first-ever stroke at least 6 months ago, resulting in paresis or hemiparesis. They must be able to move the arm opposite of the affected side but cannot currently be incarcerated.Check my eligibility

What is being tested?

The study tests a new control algorithm against a standard one used in advanced myoelectric orthotic devices that help people with limb paralysis by using muscle signals to control a robotic brace.See study design

What are the potential side effects?

While not explicitly listed, potential side effects may include discomfort from wearing the device, skin irritation from electrode contact, and fatigue due to prolonged use of the orthotic device.

Experimental Treatment

Active Control

Group I: High-Density EMG Control AlgorithmExperimental Treatment1 Intervention

Control of the orthosis is based on residual muscle activity mapped to intended movement using advanced predicted algorithms. This condition is a novel algorithm and serves as the experimental condition.

Group II: Clinically Available Control Algorithm (MyoPro)Active Control1 Intervention

Binary control of the orthosis is based on a clinically available control algorithm. This condition serves as a control. Participants will use a commercially available device, the MyoPro.

Does the research include participants above a certain age?

"As per the regulations of this medical trial, potential participants must be above 18 years old and below 70."

Answered by AI

Is this medical trial currently recruiting participants?

"Affirmative. Per the information accessible on clinicaltrials.gov, this trial is presently recruiting patients; it was first posted on March 1st 2017 and last updated on August 17th 2022 - with a requirement for 45 volunteers at one site."

Answered by AI

What is the maximum pool of people enrolled in this experiment?

"Affirmative. According to the information found on clinicaltrials.gov, this medical experiment, which was first posted March 1st 2017 and recently updated August 17th 2022 is actively seeking volunteers. 45 participants are necessary from a single centre of care."

Answered by AI

Could I be a possible candidate for this clinical experiment?

"This study seeks to enroll 45 individuals who are 18 - 70 years old and have experienced hemiparesis. Patients must meet the following eligibility criteria: never having had an ischemic or hemorrhagic stroke, 6 months since onset of a chronic stroke, continuing presence of hemiparesis, and adequate range of motion in their contralateral arm."
