WBAT is a common medical abbreviation that means “Weight Bearing As Tolerated.” It is frequently used in orthopedic, physical therapy, rehabilitation, and nursing settings to describe how much weight a patient is allowed to put on an injured or recovering limb.

If a doctor writes “WBAT” in a treatment plan, it generally means the patient can put as much weight as they can comfortably tolerate on the affected leg or foot, unless other instructions have been given.

For example, after certain types of injuries or surgery, a patient may be told:

“WBAT on the right leg.”

This means the patient may place weight on the right leg as tolerated, rather than being given a strict weight limit.

What Does WBAT Stand For?

WBAT stands for “Weight Bearing As Tolerated.”

The abbreviation is commonly used when healthcare professionals need to communicate a patient’s mobility or weight-bearing status quickly.

Abbreviation	Meaning
WBAT	Weight Bearing As Tolerated
WB	Weight Bearing
NWB	Non-Weight Bearing
PWB	Partial Weight Bearing
TTWB	Toe-Touch Weight Bearing

These terms describe different levels of weight-bearing restrictions or permissions.

What Does Weight Bearing As Tolerated Mean?

Weight bearing as tolerated means that a patient can place as much weight as they can comfortably tolerate on the affected limb.

The important part is “as tolerated.” It does not necessarily mean that the patient should immediately put their full body weight on the limb.

For example, if a person experiences pain or discomfort while walking, they may need to reduce the amount of weight they place on the affected leg.

A healthcare professional may also recommend using:

• Crutches
• A walker
• A cane
• Other mobility aids

The appropriate level of support depends on the person’s condition and treatment plan.

When Is WBAT Used?

WBAT may be used in several medical situations, particularly when a patient is recovering from an injury, surgery, or other condition affecting mobility.

It may appear in treatment plans involving:

• Leg injuries
• Foot or ankle injuries
• Hip conditions
• Knee surgery
• Fracture recovery
• Joint replacement
• Orthopedic rehabilitation
• Physical therapy

Whether WBAT is appropriate depends on the patient’s specific injury, surgery, healing stage, and doctor’s instructions.

What Does WBAT Mean After Surgery?

After surgery, WBAT generally means that the patient is permitted to put weight on the affected limb to the level they can tolerate.

For example, after certain orthopedic procedures, a surgeon may prescribe:

“WBAT left lower extremity.”

This means the patient is allowed to bear weight through the left lower extremity as tolerated.

However, WBAT instructions vary between procedures and patients. A person should follow the specific instructions provided by their surgeon or healthcare team rather than assuming that WBAT means unrestricted activity.

What Does WBAT Mean in Physical Therapy?

In physical therapy, WBAT describes how much weight a patient is permitted to place on an affected limb during activities such as:

• Standing
• Walking
• Transfers
• Balance exercises
• Gait training
• Functional exercises

A physical therapist may help the patient gradually become comfortable with weight bearing while monitoring movement, pain, strength, balance, and safety.

For example:

“Patient ambulated WBAT with a walker.”

This means the patient walked using a walker while bearing weight on the affected limb as tolerated.

WBAT vs. Non-Weight Bearing

WBAT and NWB are very different instructions.

WBAT (Weight Bearing As Tolerated) means the patient may put weight on the affected limb according to what they can tolerate.

NWB (Non-Weight Bearing) means the patient should not place weight on the affected limb.

WBAT	NWB
Weight can be placed on the limb as tolerated	No weight should be placed on the limb
May allow walking with assistance	Usually requires a mobility aid
Amount of weight depends on tolerance and instructions	Affected limb should remain unloaded

Because these instructions have different implications for mobility and recovery, patients should follow their healthcare professional’s specific guidance.

WBAT vs. Partial Weight Bearing

Partial weight bearing (PWB) means only a specified or limited amount of weight should be placed on the affected limb.

WBAT is different because it does not necessarily give a fixed percentage or number of pounds.

For example:

PWB: A healthcare professional may instruct a patient to put only a specified amount of weight on the leg.

WBAT: The patient may bear weight according to what they can tolerate, within the healthcare team’s instructions.

The exact restrictions can vary depending on the injury and treatment plan.

WBAT vs. Toe-Touch Weight Bearing

Toe-touch weight bearing (TTWB) is another type of weight-bearing instruction.

With TTWB, the patient generally places only minimal weight through the affected limb, often for balance rather than for supporting normal body weight.

WBAT is less restrictive because it allows weight bearing according to the patient’s tolerance.

These instructions should not be treated as interchangeable.

What Does WBAT Mean for Walking?

If you have been instructed to walk WBAT, you may generally place weight on the affected limb as tolerated.

However, this does not automatically mean you should walk without crutches, a walker, or other assistance.

Your healthcare provider or physical therapist may tell you:

• How much support to use
• Whether to use crutches or a walker
• How to progress your walking
• Which activities to avoid
• When to increase activity

For safety, follow those instructions rather than trying to determine your limits independently.

Does WBAT Mean Full Weight Bearing?

Not necessarily.

WBAT permits weight bearing according to what the patient can tolerate. Some people may be able to bear nearly their full body weight, while others may only tolerate a smaller amount because of pain, weakness, swelling, or another limitation.

Therefore, WBAT should not automatically be interpreted as “full weight bearing without restrictions.”

The healthcare professional’s instructions and the patient’s clinical condition determine what is appropriate.

Does WBAT Mean You Can Walk Normally?

Not always.

A WBAT order may allow weight on the affected limb, but a patient may still need a cane, crutches, walker, brace, or other support.

Walking normally depends on more than weight-bearing permission. It can also depend on:

• Pain
• Strength
• Balance
• Range of motion
• Coordination
• Healing
• Surgical restrictions

A physical therapist can help determine how to walk safely while following a WBAT order.

Examples of WBAT in Medical Notes

WBAT may appear in different ways in clinical documentation.

Example 1

“WBAT RLE.”

This means:

Weight bearing as tolerated on the right lower extremity.

Example 2

“WBAT LLE with walker.”

This means:

Weight bearing as tolerated on the left lower extremity while using a walker.

Example 3

“Continue WBAT during physical therapy.”

This indicates that the patient can continue bearing weight as tolerated during the therapy program, according to the treatment plan.

Common abbreviations may vary between healthcare settings, so the full instructions should be confirmed if anything is unclear.

Common WBAT Abbreviations and Terms

Healthcare professionals may use several related abbreviations when describing mobility restrictions.

WB — Weight Bearing

A general term referring to placing weight through a limb.

WBAT — Weight Bearing As Tolerated

The patient can bear weight according to their tolerance and clinical instructions.

NWB — Non-Weight Bearing

The patient should not place weight on the affected limb.

PWB — Partial Weight Bearing

The patient is permitted to bear only a limited amount of weight.

TTWB — Toe-Touch Weight Bearing

The patient places minimal weight through the affected limb, commonly for balance.

FWB — Full Weight Bearing

The patient is permitted to bear full body weight through the limb, subject to any other restrictions.

These terms can be used differently depending on the clinical situation, so patients should ask their healthcare team if they are unsure about an abbreviation.
