Thompson's sign is one of the methods for diagnosing lung diseases. It was developed by English physician Thomas Thompson in 1847.

The essence of the method is that when deeply inhaling and exhaling, the patient’s chest moves, which can be seen on the surface of the skin. If lines or folds are visible on the chest, this may be a sign of lung disease.

To perform the Thompson sign, you need to ask the patient to take a deep breath and exhale, then press the palm of your hand to the chest and slowly move it up and down. If lines or folds are visible on the skin, this may indicate the presence of a lung disease.

However, it should be noted that the Thompson sign is not an accurate diagnostic method and can only be used as an additional examination method. For a more accurate diagnosis of lung diseases, additional studies such as x-rays or computed tomography are necessary.
