Effects of Myoelectric Channel Count and Targeting for Upper Limb Prosthetic Control
NCT07011420 · View on ClinicalTrials.gov ↗
Study Summary
The goal of this clinical trial is to systematically evaluate whether or not two commonly held fundamental assumptions for pattern recognition control translates to functional performance when tested on individuals aged 18 years or older with upper limb absence at the transradial level while wearing a physical prosthesis. The specific aims of this study are: 1. To evaluate the effect of changing untargeted myoelectric channel count on the functional performance of transradial prosthesis users wearing a fully functional prosthesis via functional outcomes measures such as the Box and Blocks test. 2. To evaluate the effect of changing myoelectric channel targeting of a fixed number of myoelectric channels on the functional performance of transradial prosthesis users wearing a fully functional prosthesis via functional outcomes measures such as the Box and Blocks test. Researchers will perform a randomized crossover study to compare system configurations with different number of sensor channels and with various strategies for sensor placement on the limb. Participants will be assigned to a random test sequence that includes the following four different EMG channel conditions: Condition A: 4 untargeted channels Condition B: 8 untargeted channels Condition C: Up to 16 untargeted channels Condition D: 8 targeted channels Researchers will evaluate the effects of changing myoelectric channel counts on the functional prosthesis performance of individuals with transradial limb loss via functional outcome measures. Participants will: * Attend up to 5 in-lab sessions that are expected to last 4 hours. * Conduct site visits every 1-2 weeks to complete functional and self reported outcome measures with each condition. * Play virtual games with the Coapt Cuff for 15 minutes a day, 3 days a week in between visits.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT07011420
The ClinicalTrials.gov registry entry for NCT07011420 describes a study currently listed as recruiting. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 32 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Liberating Technologies, which has 5 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 6 conditions, with Amputation appearing as the primary indexed condition, and to 5 interventions — of which Experimental socket with 4 untargeted channels active is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT07011420 reports 2 study locations spanning 2 distinct geographic areas — top geographies include Illinois, Massachusetts. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
