Neurophysiological Integrity
Solutions grounded in how the nervous system actually controls movement—not inappropriate external negative bias.
Who we are
Movement without limits. Performance: Minimizing external biases.
Free Joint Motion LLC is an international company based in Weston, Florida, advancing biomechanical medical devices for sports medicine, injury prevention, and rehabilitation. Led by Professor Luis Commisso, we translate scientific knowledge into kinetic therapy innovations that respect human neurophysiology.
Flagship innovation
Multi-Ax-Sys
A semi-open exoskeleton that supports, guides, and resists natural foot motion or gestures—minimizing negative external forces while enabling multi-planar motion.
Adjustable resistance and precise tracking enhance rehabilitation, training, and clinical research.
Our approach
What we stand for
Three principles guide how we design systems, interpret movement, and partner with clinicians and researchers.
Precision Biomechanics
Multi-axis mechanisms and 3D kinetic analysis for lower-leg and foot function across clinical and athletic contexts.
Evidence & Collaboration
Partnerships with orthopedists, sports medicine practitioners, and researchers worldwide.
