I would like to propose a new term

earlgraytay:

disability parkour- compound noun, /dɪsəˈbɪlɪti/ /pɑɹˈkʊɹ/ 
1. The method by which physically disabled people who don’t have their mobility aid navigate their environment, including leaning on things, sitting down on things, asking pedestrians for help, and so on.
2. General- the ways in which all disabled people navigate an environment that is unfriendly for them. 

If you do a particularly skilful feat of disability parkour, post it in the #disability parkour tag so I can cheer you on. 🙂
