An Unmet Clinical Need
Head drop is a devastating condition in patients with a neurological disorder, such as amyotrophic lateral sclerosis (ALS). In ALS, the patients progressively lose muscle strengths and currently there is no cure. Due to weakness, a patient may have difficulty to hold the head upright or move it around. Head drop also blocks the airway of a patient, making it challenging to breathe, swallow, and speak.
