Understanding Non-Weight-Bearing (NWB) Mobility
Non-weight-bearing (NWB) means that no weight is to be placed on the injured leg. This instruction is a crucial part of recovery from conditions such as ankle fractures, Achilles tendon ruptures, or foot surgeries. Following your doctor's orders precisely is the most important factor for a successful outcome. The correct use of a walker is vital for maintaining balance and preventing re-injury during this period.
Preparing for Safe NWB Walker Use
Before you begin walking, ensure you have the right setup and environment. A little preparation goes a long way toward preventing falls and making your daily life easier.
- Proper Walker Adjustment: Your walker handles should be level with your hip crease when your arms are relaxed at your sides. When you grip the handles, your elbows should have a comfortable bend of about 15-20 degrees. This height is essential for distributing your weight properly through your arms.
- Clear Your Path: Remove all tripping hazards from your home, such as throw rugs, electrical cords, and clutter. Create clear pathways that you will use frequently.
- Wear Appropriate Footwear: On your unaffected foot, wear a sturdy, flat-soled shoe with good traction. Avoid slippers, open-toed shoes, or high heels that could affect your balance.
- Use a Walker Caddy: To keep your hands free for the walker, use a caddy or a small backpack to carry items. Never attempt to carry things in your hands while using a walker, as this compromises your stability.
Step-by-Step: The Non-Weight-Bearing Technique
Once you are properly prepared, you can begin the walking process. This method, often taught by physical therapists, should feel secure and controlled.
- Stand and Brace: Stand inside your walker, with your unaffected foot planted firmly on the ground. Hold the handgrips tightly, keeping your shoulders relaxed and elbows slightly bent. Lift your injured leg slightly off the floor, bending the knee so the foot is behind you and out of the way.
- Move the Walker: Push your walker forward about one step's length. Ensure all four tips of the walker are firmly on the ground before shifting your weight.
- Shift Your Weight: Lean forward slightly, pushing your body weight down through your arms and into the walker's frame. Keep your injured foot elevated at all times.
- Hop Forward: With your weight supported by your arms and the walker, hop forward with your good leg, landing in the center of the walker. The hop should be small and controlled, not a large jump.
- Repeat: Once stable, repeat the process. Move the walker forward, shift your weight, and hop forward with your good leg.
Using Your Walker on Ramps and Inclines
Navigating uneven surfaces requires extra caution. Always follow these guidelines unless instructed otherwise by a healthcare professional.
- Going Up: Push the walker up to the ramp and use your arm strength to push it forward. Take small, careful steps with your good leg. Keep your injured leg elevated.
- Going Down: Place the walker down the ramp first. Slowly lower your good leg, controlling your descent with your arms. Keep your injured leg lifted.
Comparison of Weight-Bearing Techniques
It's important to understand the difference between NWB and other weight-bearing instructions. Misinterpreting these can be dangerous.
Feature | Non-Weight-Bearing (NWB) | Partial-Weight-Bearing (PWB) | Weight-Bearing as Tolerated (WBAT) |
---|---|---|---|
Weight on Injured Leg | 0% weight | 30–50% of body weight, as instructed | As much as comfortable, up to 100% |
Walker Technique | Hop with good leg, keep injured leg elevated | Step with injured leg, bearing partial weight, then follow with good leg | Walk as normally as possible, using walker for balance |
Primary Support | Entirely on arms and good leg | A mix of support from arms and legs | Mostly on legs, walker for stability |
Healing Phase | Initial recovery phase, post-surgery or acute injury | Intermediate recovery as healing progresses | Later stages of healing, building strength |
Common Mistakes and How to Avoid Them
Safe walker usage is a skill that takes practice. Being aware of common errors can help you stay safe.
- Using the Walker to Stand: Never pull on your walker to get up from a seated position. This can cause the walker to tip over. Instead, push up using the armrests of your chair and place your hands on the walker once you are stable.
- Looking Down: Keep your gaze forward to maintain balance. Staring at your feet can lead to instability and falls.
- Placing the Walker Too Far Away: Extending the walker too far in front of you can cause you to lean forward and lose balance. Keep it a controlled, short step away.
- Sliding a Standard Walker: If you have a standard, non-wheeled walker, you must lift it. Sliding it causes friction and a jerky movement. If you have a wheeled walker, ensure the brakes are locked when standing or sitting.
