傷害者による“うごきの発生”に関する一考察

アイススケートの事例的研究

抄録

 This is a case study regarding the movement analysis of ice skating, which was done by an injured person, who tore the Achilles tendon on the left foot, 50 days before an ice skating training camp (instruction) in January, 2004. At that time, the man could not walk on the ground at all with his bare left foot. In that situation, how could he possibly skate?

 Through this study, I would like to clarify why this man could skate on ice as well as teach students how to skate for four days. I would also like to elucidate his ice skating skills with his injured foot and his feelings when he skated.

The story was as follows:

 “A man tore his Achilles tendon while demonstrating a skill on the vaulting horse (box) on December 8, 2003. Immediately he went into the hospital and had an operation the next evening. After that, he stayed in the hospital for three weeks. While he was in the hospital, starting on December 24, he began training, such as walking with crutches as rehabilitation. Of course, at that time, he could not walk at all without a special device (shoes), developed in the medical field.”

 In September, 2003, three months before this incident, another ice skating training camp was held. A paper was written regarding this training by this injured person, entitled“A Study regarding the Emergence of Movement: An Investigative Survey on Ice Skating”. This paper was finished during his stay at the hospital.

 On January 10, 2004, one of the three tiers (height) of the heals of the shoes was reduced by the doctor. That device is shown in the photos (1,2, and 4). The heals were still high and the ankle part was fixed. So, at that time, he could walk on the ground with some difficulty.

 Shortly after he met the doctor, he remembered the following things: While he was writing the paper regarding ice skating, he read a book with a reference, the author said, “Any person can skate who can walk on the ground.” From this idea, he got a hint. “Right now, I can walk with the medical device (shoes).” So he thought he might be able to skate in the second ice skating training camp.

 He searched for a way to skate and finally a special blade for ice skating was found. This blade was attached to the sole of the medical device (shoe). That new skating shoe is shown in the photos (3,6, and 7).

 With this unique skating shoe on the left foot and an ordinary figure skating shoe on the right foot, he could skate on ice and teach the novice students how to skate for four days. This process was recorded by a video camera and analyzed. He also analyzed his feelings while he was skating on ice. The process and results are reported in this paper.
