Abstract
A handrail article containing integral nodes continuously spaced along the axis of the rail at approximate hand spacing to reduce muscle torque strain and fatigue (Isokinetics) resulting from strength applied to overcome sliding of hand grip while sustaining balance during travel on stairways. A non-obvious application of the article is to mobile hand railings as may be found on boats, public transportation, ladders and physical rehabilitation equipment.
