TOKYO —Imagine a bicycle seat connected by mechanical frames(機械支架) to a pair of shoes for an idea of how the new wearable assisted-walking machine from Honda works．
The experimental machine, showed on Friday, is designed to support bodyweight, reduce stress on the knees and help people organize steps and stay in crouching（蹲坐） positions．Honda showed a video of its employees wearing the machine.
Engineer Jun Ashihara also said the machine is useful for people standing in long lines and to people who run around to make deliveries．
"This should be as easy to use as a bicycle," Ashihara said．"It reduces stress, and you should feel less tired．"
To wear it, you put the seat between your legs, put on the shoes and push the “on” button．Then just start walking around．
In a test run for media, this reporter found it does take some time to get used to the machine.  “I could sense how it supported my moves, pushing up on my bottom when I crouched and pushing at my soles(腳底) to help lift my legs when I walked,” he said.
The system has a computer, a motor, gears（齒輪）, batteries and sensors in it, so it responds to a person's movements, according to Honda Motor Co．
Pricing and commercial product plans are still undecided．Japan's No．2 automaker will begin testing a prototype（模型） later this month．
The need for such mechanical help is expected to grow in Japan, which has one of the most rapidly aging societies in the world．
Other companies are also eyeing the potentially attractive market of helping the weak and the old get around．Japan is among the world's leading nations in robotics technology, not only for industrial use but also for entertainment and companionship．

An interview with Benno Nigg, the sports scientist

76.

Nigg’s Answer: That is a little bit overstated. But the literature shows that shoes are a minor player in injury development. If you take a group of people and want to injure them, send them out every day for a 20-kilometre run. A lot of them will be injured in three weeks. The major factors are the distance run, the intensity and recovery time, not the shoes.

77.

Nigg’s Answer: The problem is that if you go to a store and want to find your best shoes, you don’t know what to do. Things that are sometimes done, like video analysis of your rear foot movement, may not help. The only way to assess whether a shoe is right for you is how it feels. If you feel comfortable in a shoe, it’s likely to be good for you.

78.

Nigg’s Answer: A shoe may act as a training device, making some muscles to function more effectively for a majority of users. Or it may use materials that last longer. That may have something to do with its price. However, for the average runner it is difficult to distinguish between actual functional designs and unnecessary features. Generally, the more a shoe controls movement, the more it acts like a cast, which means you lose some muscle strength, and your feet are more likely to be injured.

79.

Nigg’s Answer: Yes, for about 80 per cent of people. The major benefits are training the small muscles crossing the ankle joint, and a reduction of knee and lower back pain. However, some claims for these unstable shoes are overstated, such as the general muscle strengthening that they are claimed to produce.

80.

Nigg’s Answer: There are claims that there are fewer injuries when you run barefoot, but there is not yet enough evidence, or enough research, to prove that. If you look at performance, most papers suggest an advantage of 3 to 4 per cent. With a few exceptions, people don’t run barefoot, so it may be that it’s not an advantage, or it may be that we’re just not used to it.

The boat is not in the water, but has been standing on blocks for a year and the inside will need to be put back together as it was taken apart to redo the floors. Everything taken off is still there. Please call 440-942-2763 if you are interested.
