Filter by:This study is a non-blinded single armed pilot study aiming to apply a newly created medical device in patients with seventh nerve palsy suffering from lagophthalmus in order to determine the best way for neuromuscular stimulation of the orbicularis oculi muscle and facial nerve in order to enable eyelid closure (blink). Initially, a tailored external neurostimulation prototype will be created in collaboration with the ETH for patients with facial nerve palsy and lagophthalmos. Aim of this study is to create an efficient, safe and comfortable medical device that can achieve an effective blinking through external electrical neuromuscular stimulation of the orbicularis oculi in patients with facial palsy and lagophthalmos. Such a device can become an essential part of facial palsy treatment.
The purpose of this study is to determine efficacy of apraclonidine for patients with ocular synkinesis, who are seen in the UAB Facial Nerve Clinic.
To investigate the Effect of Kabat motor control re-education therapy on facial nerve Electro physiological responses and facial muscles function in bell's palsy. BACKGROUND: facial nerve recovery in children could be improved through facilitation of nerve regeneration which can be enhanced through Kabat motor control re-education therapy.
To test the effectiveness of a collagen-based treatment for patients complaining of long standing facial nerve axonotmesis, who are following a proprioceptive neuromuscular facilitation protocol (Kabat method), compared to a group only undergoing the Kabat method.
Purpose of the trial is to study the activations of paralyzed facial muscles in a unilateral facial nerve palsy with a multi-channel electrical stimulator. The principle of the device is to measure muscle activity of the healthy side of the face by surface electromyography (EMG) and to use this information to stimulate the corresponding muscles of the paralyzed side. The ultimate goal is to develop a prosthetic device for persons with a facial nerve palsy. The trial consists of several different studies. The studies' aims are 1. To study activations of paralyzed facial muscles by the electrical stimulation. 2. To study different stimulation pulse waveforms, frequencies, and electrode placement and their effect on the muscle activations and the tolerability of the stimulation. 3. To study whether a symmetrical movement on the paralyzed side can be achieved with electrical stimulation when compared to the movements of the healthy side. 4. To study tolerability of stimulation-elicited eye blink when watching a film and the effect of the stimulation-induced blink on the eye symptoms, the visual acuity, and the effects of the stimulation on the lacrimal fluid. 5. To develop a method for facial pacing, i.e. measuring the muscle activations on the healthy side of the face and to use this information to stimulate and activate the healthy side of the face. Forty subjects with a chronic facial nerve palsy are recruited to the studies. Each subject can participate in one or several studies. Another forty subjects with an acute facial nerve palsy are recruited to the study on the tolerability and effect on the eye symptoms. Additionally, altogether ninety healthy volunteers are recruited to the studies in order to gather preliminary information on the tolerability and the effects of the stimulations.
The objective of the research is to determine whether the MyotonPRO has a valid and reliable application in facial, head and neck surgery. In addition, the study aims to compare this new technology with current electromyography.
