Abstract

Objectives : Facial nerve palsy causes blurred vision and ocular discomfort due to deficits in blinking and eye closure. The objective of this study was to determine whether eye-blinks could be elicited by electrical stimulation and whether electrically induced blink would have an effect on the visual acuity and ocular symptoms in patients with acute facial nerve palsy. Methods : The zygomatic branch of the facial nerve of fifteen participants with acute facial nerve palsy was electrically stimulated in order to elicit a blink. In successful cases, the participant proceeded with a two-hour TV watching session in which an electrically induced blink was delivered every 5 seconds. The control condition consisted of an otherwise similar TV watching session without electrically induced blinking. Subjective ocular symptoms were evaluated with a Dry Eye Questionnaire and visual acuity was assessed with a Logarithm of the Minimum Angle of Resolution (LogMAR) chart before and after both sessions. Results : The stimulation produced a blink in 8 participants (53%). The visual acuity in the affected eye decreased during the control session, whereas no significant change occurred during the stimulation session. The ocular symptoms were significantly reduced during the stimulation session. Conclusions : Electrically elicited blink is a promising method for reducing the eye symptoms in individuals with acute facial nerve palsy. [ABSTRACT FROM AUTHOR]

Abstract

A device for studying facial pacing for people who suffer from unilateral facial paralysis is presented. The device is able to measure electromyographic (EMG) signals from the healthy side of the face and simultaneously activate the paralysed side with electrical stimulation. Electronics designed for the device are integrated to a single tabletop unit together with a myRIO embedded hardware device by National Instruments (NI). The presented device is designed to fulfil the safety requirements of the Council Directive 93/42/EEC of the European Union concerning medical devices and IEC 60601 standards. The device is powered by a commercial medical grade power source. The custom electronics include isolated measurement and stimulation amplifiers that feed the signals to and from the myRIO. Complex real-time processing can be carried out in the myRIO's FPGA circuit for detecting muscle activations and producing appropriate stimulation signals. The functionality is programmed with NI LabVIEW. The device is controlled wirelessly via a computer interface, and the measured data is logged to the computer. Clinical study with the device is about to be started at the Tampere University Hospital. First trials will determine and compare the required stimulation signal waveform parameters for transcutaneous activation of facial muscles of healthy participants and patients suffering from unilateral facial paralysis. Four measurement and four stimulation channels of the device enable studying different electrode configurations and stimulation patterns for recognizing and reanimating symmetrical facial expressions in the future.

Abstract

Hirayama is a form of cervical myelopathy affecting mainly young men. The cardinal features include progressive, either symmetrical or asymmetrical muscular weakness and atrophy of muscles innervated by C7-Th1 motoneurons. The application of soft daytime collar during the early stage of illness can halt the progression of illness.
