    Hi not sure how it would work but my dad loved playing guitar and he suffered a TBI and lost functioning of his right wrist. He still can play all the chords with his left hand but cannot strum the strings with his right hand. I am reaching out to this site to see if you can design a tool that allows my dad to strum a guitar again. I realize this is a long shot but I wanted to give it a try.


    This should be very doable, as I’m aware of at least a few similar existing projects. It would be helpful to know a bit more about what your dad is still able to do.

    For example, CanAssist has developed a foot-operated guitar strummer: (I’m not sure how they handle tech requests, but might be worth asking directly. Otherwise, that design could probably be used as inspiration for a similar solution)

    Stan Cassidy has also worked on something similar.


    Hi Julie,

    I teach a high school Engineering class, and my students are interested in helping you design a solution to this problem. We would love to talk to you further and understand your dad’s strumming needs better.

    If you’re interested, I would love to schedule a Zoom with you or continue the conversation over email.

    Best wishes,



    @juliehumphries if that foot operated strummer would be a suitable solution, you can try contacting CanAssist directly:


    @mmc_jake Thank you!! I’m going to contact Canassist directly.

    My dad can moves his arm and forearm but slowly, not fast enough to produce a strum and he cannot rotate his wrist all all. It’s like his wrist is locked.


    @luisal The hat sounds great. I can answer any questions you have over email. Does that work for you?


    That’s great! Thank you! I just sent you a chat/DM with my email address.
