Wide Handbook to Mobility Aids: Tri Walkers, Canes, Crutches & Zimmer Frames

Tri walkers (three-wheeled rollators) offer great balance support with more mobility. Their triangular wheel configuration—usually one swivel wheel at the front and two fixed wheels at the back—is perfect for getting through tight spaces.

Key Features

• Lightweight (most under 6kg) for easy to handle

• Compact and nimble for getting through narrow doorways

• Folding frames for storage and transport

• Reliable brakes with locking mechanisms

• Storage bags for carrying your bits and bobs

• Supports users up to 115-136kg (18-21 stone)

Using Your Tri Walker Safely

1. Stand up straight with good posture, behind the walker

2. Hold both handles with a natural grip, arms by your sides

3. Push the walker forward slightly, then step into it

4. Keep upright rather than leaning over the frame

5. Apply brakes by squeezing the levers; lock them by pushing down until they click

6. For a small obstruction, tilt the front wheel up

Always make sure your tri walker is fully open and locked before use and be extra careful on uneven surfaces or slopes.

Canes provide gentle, lightweight support—ideal for those who need just a little help with balance or stability. They’re the least obtrusive mobility aid, giving discreet help while allowing natural movement.

Types

• Single-point canes: Basic design supports up to 25% of body weight

• Quad canes: Four-point base for more stability

• Offset canes: Curved handle puts weight directly over the shaft

• Folding canes: Collapsible for easy transport

• Seat canes: Has a small fold-out seat

Handles

Different handles for different needs:

• Derby handles: Curved right-angle design, hooks over arm when not in use

• Fritz/Fischer handles: Ergonomic for arthritis sufferers

• Ergonomic handles: Contoured for left or right hand

• Crook handles: Traditional curved shape

• T-handles: Simple right-angle design

Using a Cane Correctly

1. Sizing: Handle should be at your wrist crease when arms are hanging down

2. Positioning: Hold cane on your stronger side (opposite your weaker/injured leg)

3. Walking: Move cane forward with your weaker leg

4. Stairs: When going up, lead with your stronger leg; when going down, place the cane first for support.

A properly sized cane should allow your elbow to bend slightly (10-15 degrees) when in use.

Crutches give big weight-bearing relief for injuries or surgeries to one or both legs.

Types of Crutches

• Underarm (Axillary) Crutches: From ground to armpit with hand grips; good for short term use

• Forearm/Elbow Crutches: Forearm cuffs with hand grips; better for long term use

• Platform Crutches: Forearm platforms for those with wrist issues

Proper Crutch Technique

1. Proper fitting: Ensure a proper fit by allowing 2 to 3 finger widths of space between the armpit and the crutch pad, and adjusting the handles so the elbows are slightly bent—around a 30-degree angle

2. Weight bearing: Weight through hands and arms—never armpits

3. Basic walking: Move crutches forward with affected leg, then step through with unaffected leg

4. Stairs: When going up stairs, step with your stronger (unaffected) leg first. As you go downstairs, move your crutches and injured leg down first, then follow with your stronger leg.

To sit down safely, hold both crutches on your stronger side, use your free hand to feel for the chair behind you, and gently lower yourself into the seat.

Zimmer frames (walking frames) are the most stable of all mobility aids. These freestanding four legged supports are for those with big balance or strength issues.

Features

• Lightweight aluminum

• Four legs with rubber feet for stability

• Available in standard (64cm), domestic (53cm) and narrow (49cm) widths

• Height adjustable in 2.5cm increments

Types

• Standard frames: Must be lifted with each step; maximum stability

• Wheeled walkers: Front wheels allow pushing rather than lifting

Using a Zimmer

1. Stand inside the back of the frame

2. Lift and place it a comfortable distance ahead (for non-wheeled frames)

3. Step into the frame, use the handles for support

4. For wheeled frames, push forward steadily

The frame should be adjusted so your elbows bend 15-25 degrees when gripping the handles.

Mobility aids aren't just useful appliances – they're freedom keys, confidence boosters and participation keys to life. The correct aid, properly fitted and used, will enable you to live your life with dignity and safety.

Don't wait until you need professional guidance when selecting a mobility device. What suits one individual will not suit another and your needs will evolve over time. With the proper assistance you can continue to move about in life confidently and safely.
