Which statement is true about TTWB/TDWB compared with NWB?

• A. TTWB/TDWB allows touch without weight; NWB prohibits weight and contact
• B. TTWB/TDWB allows weight; NWB prohibits weight
• C. TTWB/TDWB allows touch with weight; NWB allows full weight
• D. TTWB/TDWB allows full weight; NWB allows touch only

Answer: (C)

Weight-bearing status is about how much load the injured limb is allowed to carry during rehab. Toe-touch weight bearing (TTWB) or touch-down weight bearing (TDWB) means the toes can touch the floor for balance and proprioceptive feedback, but the limb should not bear the body's weight; only a small amount of weight may be allowed through the toes. Non-weight bearing (NWB) means no weight is placed on the involved limb at all, with the body’s weight supported by the opposite leg and any assistive devices. So, TTWB/TDWB indeed involves touch with some weight through the limb for balance, whereas NWB prohibits weight bearing entirely. That contrast is what the statement highlights as the true distinction between TTWB/TDWB and NWB.
