Are you asking for a sentence using 'walking stick' as a motility aid?
When some jackass asked me about my needing a cane, I beat the jerk over the head with my 'walking stick'! 'D
P.S. "Walking Sticks" are not motility (i.e. walking) aids. Instead, they're typically used for hikes in the woods, where you can alternate using them for balance, investigating interesting caverns without being bitten by angry badgers, or swing around whenever you break into song.
For that matter, as a one-time collector of antique canes, they were once a fashion statement and not an 'aid', as they had metal tips (which aren't terribly stable when the users isn't) and slip on wet or slick surfaces.
The main difference between these are walking sticks are longer with a heavy head, not typically containing a handle. A decorative cane is thinner, typically with a metal end which 'taps' when walking on most floors to attract attention to the dandy using it, while medical canes are thick wood or steel devices with plastic non-slip pads on the bottom, and are a gateway device to walkers with attached tennis balls.
When I was working on Wall Street, years ago, I walked with antique canes and wore customized 'braces' (suspenders for the non-pretentious) as my way of standing out from the crowd.
By the way, there's no hyphen needed for "walking stick", since it's a simple adjective modifying a noun and not a compound word with a separate meaning (i.e. it's simply a stick used for walking, not a distinct entity in itself).
