Abstract
A treatment device and a method for simultaneously applying vibrations and percussion forces to a predetermined area of a patient's body adjacent the lungs of the patient. The device comprises a housing having a handle portion. A clapping head is disposed exteriorly of the housing and connected to a reciprocable element which is imparted a set low frequency reciprocation movement by a low frequency generation device to impart a clapping action to the head. The head has a contact surface for engagement with the predetermined area of the patient's body. An independent vibrator element is also provided and has a body engaging member which is disposed in relation to the clapping head and connected to a vibration generating device capable of vibrating the vibrator element at a higher predetermined frequency than the reciprocation movement of the clapping head. Preferably, the clapping frequency is in the range of from 0.5 Hz to 2 Hz and the vibration frequency is in the range of from 40 Hz to 70 Hz.
