For transfer belts, a sound approach must assess the person's weight bearing, cognition, balance, pain, skin and abdominal conditions, transfer direction, belt type and size, buckle closure, finger clearance, clothing, caregiver training, footwear, floor, destination stability, and need for a lift or second helper.
Here, the main issue is the interpretation of results. It uses weight bearing, transfer plan, and handhold to explain what changes the outcome, where uncertainty enters, and which response is proportionate.
