I know I am a little biased but I think the Volaris walking aids are great for helping people get around the home as well as outside safely. Particularly for people with Wikipedia reference-linkParkinson's disease.

You can fully customise them to suit individual needs.

The slow down brake is something that OTs and Physios look for particularly with Parkinson's because the shaking (tremor), and slowness of movement can sometimes make it difficult for the users to slow walking aids down by themselves. The slowdown brake acts like a resistance wheel on an exercise bike where you can screw down a small wheel onto the larger wheel and increases the resistance of the walkers’ movement so it does not roll away too fast. It allows you to slow the walker down depending on the needs of the user.

There are many other accessories available which will enable you do adapt the walker to individual needs depending on the severity of the case.
