Jun 18, 2025

Overview

This lecture covers the proper fitting and use of crutches, canes, and walkers, including fitting guidelines, safe movement techniques, stair navigation, and sit-to-stand instructions.

Crutches: Fitting and Use

  • Crutches must be adjusted for patient height, including the handgrip and crutch length.
  • There should be a 2-3 finger (1-1.5 inch) gap between the axilla (armpit) and crutch rest pad.
  • Handgrips should align with the top of the hip line, elbow bent at ~30 degrees when holding.
  • Weight should be on handgrips, not underarms, to prevent nerve damage.

Crutches: Gaits and Mobility

  • Begin with a gait belt and start in tripod position (crutches 6 inches diagonal from feet).
  • 2-point gait: Move opposite crutch and foot together (right crutch/left foot, left crutch/right foot).
  • 4-point gait: Move each crutch and foot separately in sequence.
  • 3-point gait: Move both crutches and injured leg together, then the non-injured leg.
  • Swing-to gait: Both crutches forward, then legs swing to crutches.
  • Swing-through gait: Both crutches forward, then legs swing past crutches.

Crutches: Stairs and Chairs

  • Going up stairs: "Good up, bad down" — step with the good leg first, followed by crutches and bad leg.
  • Going down stairs: Crutches and bad leg first, then good leg.
  • To sit: Back to chair, move crutches to injured side, grip handgrips, extend injured leg, sit.
  • To stand: Crutches on injured side, extend injured leg, push up with non-injured leg and handgrips.

Cane: Fitting and Use

  • Adjust cane so the top is at the greater trochanter or wrist crease when standing.
  • Elbow should be flexed 15-30 degrees.
  • Hold cane on the strong side.
  • To walk: Move cane and weak leg forward together, then strong leg.
  • To ascend stairs: Good leg, then cane and bad leg; to descend: cane and bad leg, then good leg.
  • To sit: Back to chair, cane on side, hands on armrests, sit with weak leg extended.
  • To stand: Place cane on strong side, lean forward, push down on cane and armrest, stand with strong leg.

Walker: Fitting and Use

  • Adjust walker so wrist crease lines up with handgrips; elbows flexed 15–30 degrees.
  • To walk: Place walker so back legs align with middle of feet, lift and set all four points down, move weak leg, then strong leg.
  • Patient should look ahead, not at their feet.
  • To sit: Back until chair touches legs, extend weak leg, hands on armrests, sit.
  • To stand: Walker in front, hands on armrests, lean forward, extend weak leg, push up, then grab walker handgrips.

Key Terms & Definitions

  • Tripod Position — Standing with both crutches 6 inches diagonally from feet for stability.
  • 2-point/4-point/3-point Gaits — Crutch walking patterns for different levels of weight bearing.
  • Swing-to/Swing-through Gaits — Patterns where both legs swing to or past crutches.
  • Gait Belt — Safety belt used to assist patients during ambulation.
