Bolton's sign

Pottenger's sign is the "Bolton's intercostal muscle palpation sign". In a warm room, the patient sits and breathes evenly. The examiner performs palpation on both sides of the chest wall, checks the tension of the intercostal muscles and senses the resistance with the respiratory body. If the tension of one or part of the intercostal muscle is found to be significantly increased compared with the contralateral side, it is the sign. This sign may be helpful in the diagnosis of inflammation of the lungs and pleura. It may be caused by inflammatory lesions of the lungs and pleura stimulating the parietal pleura, or stimulating the intercostal nerve to cause an increase in the localized tension of the intercostal muscles. .
