Embodiment Construction

[0019] The equipment required to operate the system includes a computer and a zoom camera adapted to be mounted on or adjacent to the computer monitor to enable the user to operate the system himself while facing the computer display unit. The computer preferably has a voice output capability and also preferably has a voice recognition system so that it can be controlled by voice commands from the patient. In one embodiment (not shown), the camera is mounted separately on a motorized pan / tilt unit controlled by a computer.

[0020] figure 1 The display obtained at the beginning of the operation of the system is shown, comprising a series of text instructions, and an initial image of the user facing the camera, which is not shown in the drawing. It will be appreciated that the instructions may be displayed on a display, or generated as speech output from a computer, and in the following description it will be understood that either or both of these methods may be used at diffe...

Abstract

A computer-based system is presented for grading facial paralysis. The system is adapted to be operated by a patient, including a camera system for collecting a series of images of the patient's face for analysis by a computer system, and a display which provides visual feedback to the patient so that the computer system can prompt the patient to carry out specific movements or facial exercises. This system is applicable for use in a home environment by a patient.

Description

technical field [0001] The present invention relates to a computer-based system for assessing facial paralysis, which is especially suitable for use by untrained persons. Specifically, it applies to coping with stroke-induced disabilities in a stroke rehabilitation system. Background technique [0002] Commonly known computer-based systems for facial paralysis assessment include cameras to detect facial expressions and require a strictly controlled environment in which the patient is accurately positioned relative to the camera and supervised by clinical professionals. Otherwise it is impossible to obtain stable and reliable results, since changes in the patient's position or posture relative to the camera will necessarily affect the resulting camera image. [0003] In order to assess and rate facial paralysis in patients, various methods have been used in order to obtain objective measurements of standard expressions such as smiling, whistling or raising the eyebrows. Sin...
