COMMON QUESTIONS
The essentials.
How is LegMaker different?
It is designed to attach directly to a compatible manual wheelchair, so the user can remain seated in their own chair.
Which motion modes are planned?
Passive, assistive and active cycling. Some features remain in development and should not be considered validated.
Can a clinical team evaluate it?
Yes, teams can discuss an evaluation. LegMaker is investigational; clinical outcomes and commercial availability have not been established.
PHYSICAL AI + CONTROL
Adaptive by design.
LegMaker’s investigational control architecture explores responsive lower-limb exercise and measurable sessions.
