Arm-length positioning catches hazards that project into the walking path above cane sweep height: a hanging planter, an open cabinet door swung inward, a chair back, or a counter edge. The forearm or back of the hand absorbs the impact first, giving the traveler time to react.
Coverage is intentionally incomplete. The upper position leaves the waist and legs uncovered; the lower position does not shield the head. Neither approach alerts the traveler to stairs, ramps, curbs, or platform drops. That limitation is why protective hand and arm positions belong alongside—not instead of—a primary mobility aid or guide.
