Long Canes for the Blind -長い白杖

Daniel told me that a long cane is waiting for me.

Daniel is known as a tongue click echolocation guy, but before that, he is the one and only certified mobility coach as a completely blind man in the United States.
He once asked me that he bets I use a short cane that comes to the chest height.

He insists we the blind should use long canes for maximizing the perceptual mobility. Does He means, his perceptual mobility training consists of echolocation and long cane technique?

In his essay, he mentioned that using a cane is the part of perceptual tools, along echolocation that includes tongue-clicking active sonar and passive sonar, to understand what's around.

From his experience, a longer cane generally helps people of all ages to gain mobility. For children, he found out the cane of their height will give confidence in walking around. When they walk with parents, or adults, they tend to have shorter steps and try to catch up with the speed of adults, so a long cane provide information of further ahead.

For adults, longer canes generally give confidence, no longer need to bend over the back to find out the objects on the surface. Back is straightened and walk with more confidence!

I indeed find my cane is too short: When I tried to find a wall on the side, I had to extend my arm so I am often bend my body to forward. I always wished I wanted a long cane, so this will be a great chance to acquire it!

By the way, a long cane will be heavier, bulkier and it may increase a chance to collide with other people, but Daniel says we will get used to it.

I might cover about the issue of cane length after I talk with Daniel about it in person.

ダニエルが、「長い白杖を用意して待ってます。」ってことです。


ダニエルは、「舌打ち男」とか「ソナー男」とばかり呼ばれていますが、実は盲人で全米唯一の機能訓練士でもあります。
なので、歩行訓練の際は、舌打ちだけではなく、杖も使います。

彼の過去の論文を拝見すると、白杖は体の一部となり、聴覚やその他の感覚と共に、移動するのに重要な道具だと言っています。

通常は、アメリカでも日本でも、みぞおちの上くらいの長さの杖が適当とされています。

しかし、杖が短いと、なかなか前に進めない傾向があるようです。

ダニエルが教えた生徒や彼自身の経験から、子供たちの場合は、長い杖を持たせると、色々なところを探りたがるそうです。杖が長くなるだけで、安心感と好奇心が増す、真理的作用があると考えられます。
また、子供は大人と一緒に歩くとき、歩幅が小さく、追いつくためにかなり早足になる時、長い杖のほうが先を探ることが出来るため、有利と考えるようです。

大人の場合、杖が短いと、周囲を把握しようとして手を無理に伸ばしたり、前かがみ気味になり、姿勢が悪くなります。そういう人に長い杖を使ってもらうと、姿勢が安定するそうです。

私はここ福岡での歩行訓練の時、杖を構えたら2歩先の情報が分かると言われましたが、長い杖だと、さらに一歩先が分かるので、私個人的にも、安心して歩行できるかな、と思います。

杖の長さに関しては、ダニエルがこだわっているところなので、彼と話が出来たら、またブログに投稿します。

  1. I am enjoying your blog. You are really documenting the world you live in. Hopefully I am learning a bit more about persons with your disability. Have a safe flight!
