There are many kinds of sticks used for different purposes.
Walking stick when the physical condition of the body requires it. When the body regains its strength then shouldn’t be used because they become “crutches”.
Ski pole , which used from skiers to improve balance, speed, acceleration. Average skiers use different poles than more advanced skiers because their needs are different.
Climbing stick are used for similar purposes too. To make walking easier and prevent the body from harms and fatigue. They are also used as tools to inspect the soil.
As I see it, sticks can support walking, improve walking or even impend walking. It depends on the individual what they want to reach and what they consider as “enough”, I think.
