Prototype and design work
Project materials describe wheelchair-mounted prototype hardware, lower-limb pedaling concepts, assembly designs and prior hands-on user feedback. Independent verification reports are not yet published here.

Evidence & Validation
An evidence-status overview for LegMaker, a wheelchair-integrated lower-limb exercise platform. We distinguish information reported to date from ongoing verification and future evaluation plans.
What we can substantiate—and what we still need to test
LegMaker is investigational. Prototype demonstrations and engineering plans should not be interpreted as proven clinical outcomes, FDA clearance, market availability or evidence of reimbursement.
Engineering acceptance
Proposed test targets include loaded runtime, torque sensing, adjustable resistance, wireless performance, secure attachment and safe stopping behavior. These are targets, not certified results.
Usability research
Research planning describes potential evaluations with AURC/Shepherd Center and Texas State University. Partner scope, safety review, agreements and participant protections must be confirmed before testing.
Evidence standard: We will publish dated test methods and acceptance criteria where appropriate, identify authors/reviewers, disclose sample sizes and limitations, and clearly distinguish measured outcomes from design goals.
Research and quality roadmap
Configuration & traceability
Released CAD bill of materials, assembly instructions, first-article inspection, component traceability and supplier verification.
Objective verification
Documented attachment, endurance, motor-control, sensing, battery, emergency-stop and communications tests.
Accessible evaluation
Defined tasks, consent, applicable research oversight, participant feedback and usability reporting once approvals are in place.
