Full-Body Biomechanically-Aligned Garment System

The companion paper (Sooh, 2026a) demonstrated that orienting sleeve fabric grain to match
glenohumeral external rotation (15 to 30 degrees) reduces friction during garment entry and
provides tactile reinforcement of healthy shoulder mechanics. This paper extends that principle to
a complete full-body garment system. Human movement involves integrated kinetic chains in
which force transfers sequentially through multiple joints. All major joints rotate during functional
movement: hips during walking, spine during twisting, shoulders during reaching. Current garment
construction ignores these rotational patterns, placing fabric grain parallel to limbs at 0 degrees
and creating resistance throughout the kinetic chain. A full-body garment system with fabric grain
oriented to match each joint's natural rotation angle provides zero-resistance entry and exit across
all garment openings, continuous tactile reinforcement of biomechanically correct movement
patterns, passive rehabilitation through daily micro-corrections, and injury-prevention feedback
when joints drift into unsafe positions. This paper documents the biomechanical framework,
construction specifications, transition zone engineering, material requirements, and primary
applications for the full-body system. Markets include medical rehabilitation, elite athletic
performance, occupational health, and aging populations.
