Which is a contraindication for body weight support (BWS)?

• A. BWS 40%
• B. BWS > 55%
• C. BWS < 10%
• D. Age under 18

Answer: (B)

In body weight support training, the goal is to unload enough to allow safe stepping while keeping enough weight-bearing to drive normal gait and meaningful neuromuscular input. If you unload more than about half the body weight (roughly greater than 55%), the patient isn’t bearing enough load to activate the typical gait patterns or provide sufficient proprioceptive feedback. This reduces the training effect and can create an unloading pattern that doesn’t transfer to real walking. That’s why heavy unloading beyond about half the body weight is considered a contraindication. A moderate level of support, like around 40%, is commonly used in early rehab and is not contraindicated. Very light support (near full weight bearing) can be used as you progress, though it may be less about unloading and more about aiding stability. Age under 18 isn’t a blanket contraindication; pediatric BWSTT can be appropriate with proper safety and equipment.
