Abstract
We investigated whether the instruction to bear full or partial weight is accurately followed by the patient after total hip arthroplasty. The investigation was made with a measuring insole. It was revealed that the patient is able to follow the order only if he receives training with and is controlled by an acoustic and/or optical biofeedback system with every step he takes. Training, even very intensive repeated training, with only a scale is futile. The patients’ strides are made with either a full weight load, when they should not do so or with only a partial weight load, when they should bear full weight.
