A research group led by Professor Toshiaki Suzuki, Dean of the Graduate School of Kansai Medical University, found that in patients with hemiplegic cerebrovascular accidents who have difficulty moving their mother's fingers on the paralyzed side, the extension of the entire fingers on the paralyzed side is reflected in the movement image of the entire fingers on the non-paralyzed side. Announced that combining exercise is effective.
In order to devise an appropriate exercise therapy using exercise images for patients with cerebrovascular accident hemiplegia in which the muscle tone of the muscle group on the paralyzed side of the thumb ball is increased, the research group of Professor Toshiaki Suzuki et al. We investigated an effective exercise therapy method using the F wave, which is an index of excitability.
For exercise therapy, a method using four exercise images was set.Task 1 is an image of thumb extension on the paralyzed side, Task 2 is an image of extension of the entire thumb on the paralyzed side, Task 3 is an image of extension of the thumb on the paralyzed side and an exercise of extension of the thumb on the non-paralyzed side at the same time, and Task 4 is an image of the entire thumb on the paralyzed side. The extension image and the extension movement of the entire non-paralyzed finger were performed at the same time.The median nerve on the paralyzed side was stimulated before and during the task, and F waves were recorded from the muscles on the thumb ball.
As a result, the amplitude F / M ratio of Task 4 was lower than that of other tasks.The results show that exercise therapy, in which the extension image of the entire paralyzed hand and the extension of the entire non-paralyzed hand are performed at the same time, reduces the excitability of the anterior horn cells of the spinal cord of the muscle group on the paralyzed mother's finger. all right.
Therefore, for patients with cerebrovascular accident hemiplegia who have difficulty in moving the thumb on the paralyzed side, it is more effective to perform a movement image that extends the entire thumb on the paralyzed side rather than performing a movement image focusing on the thumb on the paralyzed side. It was found that it is most effective to perform the paralyzed side finger extension movement image and the non-paralyzed side hand extension movement at the same time.
