What does TTWB/TDWB mean?

What does TTWB/TDWB mean?

• A. Can touch or rest foot on floor but no weight applied
• B. No contact with ground
• C. Weight bearing as tolerated
• D. Full weight bearing

Answer: (D)

Weight-bearing status in rehab describes how much load the injured limb is allowed to bear. TTWB and TDWB mean toe-touch or touch-down weight bearing. The foot may rest on the floor for balance, but no weight should be transmitted through the limb. The ground contact is used mainly for stability and proprioceptive feedback, not to bear load. This is different from full weight bearing, where the leg supports all body weight, or weight bearing as tolerated, where the patient can bear as much weight as pain allows. So TTWB/TDWB indicates minimal contact for balance only, not meaningful weight through the leg.
