Amidah for Wheelchair Users
Question
Hi, I'm a wheelchair user (paralysed from chest down) and I've been wondering what I'm supposed to do during Amidah. There's no wheelchair-accessible shul near me, so I haven't been in years and daven at home. Obviously I don't stand, and based on this (https://judaism.stackexchange.com/questions/9795/a-wheelchair-users-taking-steps-before-shmone-esre) I've always moved my chair roughly 3 steps - I also try to make sure it's 3 distinct little taps to my wheels, so it's similar to steps. But I've never known what to do about bowing; Ashkenazi custom is to bow from the knees, which I can't do, and equally if I bowed from the waist my body would flop fully onto my knees because I have very little trunk control! Should I bow from the neck / chest, even though it's not a proper bow? Or should I put my siddur down and brace myself with my arms so I can bow from the waist? Likewise, I can't move my legs so I can't hold them together; I can position my feet together, but not my knees unless I use my hands or a Velcro strap or something (which I do for sport). But something about that seems weird to do during prayer.
I realise I'm over-thinking this, but (a) that's Jews for you, and (b) they're interesting questions when considering where each rule comes from!
Thanks for your input
