Here is your challenge:
In the comments section, write everything that this survivor could do better in order to get up the stairs more safely.
We all know that falls are bad.
Falls can kill you. For survivors, falls are especially bad. Stroke affects balance, coordination, strength, and any number of other things that can lead to an increased risk of falls. On top of that, survivors tend to fall towards their affected side. In the affected side tends to be more osteoporotic. So have at it. This is good place to start as anywhere. What is this gentleman doing wrong? How do you do differently? What can you suggest?
