Abstract
An oscillatory PEP therapy device (100) has valve (10) mounted at the end of a rocker arm (12) such that the valve is opened and closed during expiration through the device, thereby causing displacement of the rocker arm up and down. The housing (2) of the device (100) is transparent so that the camera (20) on a mobile phone (200) can be positioned to view displacement of the rocker arm (12) during use. The phone (200) is programmed to extract a signal indicative of the frequency of oscillation of the rocker arm (12) and this is displayed on the screen of the phone to provide feedback to the user.
