简要总结
This is a single-center, open-label clinical study. Up to 11 subjects will be enrolled to use the Neuro-trigger device for blinking stimulation for a duration of 14 days.
详细描述
Facial paralysis is a well-known and severe condition. The paralysis can be permanent or temporary, depending on the cause and on the severity. It usually affects only one side of the patient's face, and so it makes the affected side of the face look like it is drooping.
The two facial nerves control each the muscles on one side of the face. A damaged facial nerve distal to the impaired area is dead and is unable to carry messages from the brain to the facial respective muscles either completely or partially, depending on the level of damage. This leads to muscle weakness, twitching or paralysis. In addition, damage to the nerve can cause the eyelid to drop, and the angle of the patient's mouth can also be twisted, usually towards down. In some cases of bell's Palsy, the nerve is capable to regenerate into the tunnel where it run before, and some studies have shown that stimulation may facilitate the growth toward the desired direction.
Under normal circumstances, the human eye blinks every 2-10 seconds. With every blink the eyelid spreads moisture over the cornea. With facial paralysis the ability to blink may be impaired or absent all together.The dry eye syndrome gets exacerbated since damage to the facial nerve also impairs the signal to the tear gland to generate tears, which mean that the production and secretion of tears in the affected eye is impaired.
With no effective treatment so far, and as paralysis persists, the severity of secondary damage to the eye increases including irritation of the eye (conjunctivitis), ulceration of the cornea, and it might cause severe disability and even blindness.
All the treatment options currently offered in the cases described above are partial and insufficient, and are aimed at alleviating symptoms and providing relief only.

结局指标
主要结局
To evaluate the Neuro-trigger device usability in the treatment of unilateral facial paralysis subjects.
时间窗: 14 days treatment
Examining the optimal location of placement for the Neuro- trigger's electrodes. * Establishing the level of pain generated if any, during device implementation and stimulation. * Exploring the personal adjustment process of the precise pattern of stimulation (strength, intensity, other features) to achieve eye blinking for different patients
次要结局
- The secondary study objective is to evaluate the safety and effectiveness of the BlinkER in achieving eyelid closure during the study visits with facial nerve palsy.(14 days treatment)
