For pALS who can move their heads, but have difficulty with speaking and moving their limbs, a hat-mounted pointer and communication board may be a helpful solution. Best practice is for it to be used as a “rapid access” method even if they have an eyegaze device or other higher-tech communication method. High-tech devices are wonderful, but are not always reliable in every environment or setting. This is a means of enabling communication quickly in multiple settings.
The highest quality laser pointer I’ve found is offered by Low Tech Solutions. Its cost to buy starts at $129.99 and they also offer a 2-week rental. I have found nothing negative about this product yet; it’s very adjustable and lightweight with good battery life.
