The current World Record for dynamic bowling by a wheelchair user is an amazing 243 -- the verified scoresheet and explanation are below...

Checkout the last game above... Jon Musgrave's extremely impressive 243 is the current world record for dynamic bowling by a wheelchair user (click HERE for why this is a legitimate world record, and to see the record scores in multiple categories).  What makes Jon's score particularly impressive is that he is paralyzed from roughly his chest down (he's a C4-5 quadriplegic) -- and has limited arm ability.  But he has enough arm ability to operate his power wheelchair by hand joystick  (so he's also the world record holder for males who drive by joystick -- but anyone who can operate a wheelchair safely can bowl) and Jon has a passion for bowling.  Jon usually bowls from 2 to 5 days a week, and his goal is to be the first dynamic wheelchair bowler to ever bowl a perfect 300!
