Q & A

Answers to concerns such as whether it can be used even if the contracture is strong

So that everyone can safely and securely carry out functional recovery training on their own

Unlike using the world's most advanced electric rehabilitation assist devices, convenience stores and mobile phone services that are familiar to many people, there are many unclear points. Therefore, we answered in advance to any questions that customers tend to contact before introducing the system.

Please feel free to take a look if you have any concerns, such as the guideline for the number of trainings using the equipment in a day and whether or not it can be used depending on the degree of contracture. We also welcome inquiries about our products via form or phone.


  • Is it a medical device?
    Since it is not a medical device, you can use it at your own discretion.
    * Medical devices may require a doctor's prescription.
  • Who can use it?
    Anyone who is said to be better off moving their fingers and who does not have any pain when moving can use it.
    * If you have difficulty making a decision, please consult your doctor.
  • How many times do you move in a day?
    It is said that it is good to continue 2 sets of 300 times (about 20 minutes) every day, but to prevent muscle pain in the arms etc., start using it gradually from about 100 times according to your physical condition. It is good to increase it.
    * Please do not overdo it and use it while checking your physical condition.
  • Can I use it if my contracture is strong?
    The stronger the contracture, the more change can be expected.
    At first, it hardly moves, but in many cases, the range of motion expands as the tension gradually increases.
  • Is it possible to control the strength?
    The strength cannot be changed. Many people who are paralyzed (especially those with contractures) feel more nervous and harder when trying to move with more force.
  • What are the benefits of using air?
    It prevents excessive force from being generated and is highly safe. You can move according to the user's symptoms (hardness of fingers).

If you can easily carry out functional recovery training yourself at home, you will have more time for training, and as a result, it will be easier for you to recover movements of your fingers and ankles smoothly. It's easy to imagine that strength training in sports can be more successful if you spend more time. However, excessive strength training carries risks such as muscle soreness, sports injuries, and sports injuries. This also applies to functional recovery training, and care must be taken to maintain moderation and not overload the body.

For example, if you feel pain when bending and stretching your fingers, it will be difficult to use the Power Assist series. Also, if you overtrain your muscles more than 500 times at once when you move them for the first time in a long time, it may lead to muscle pain and damage to your muscles. We answered in advance about the functional recovery training equipment that we aim to spread to the general public in the future, and the points that many people tend to have doubts about when introducing these.
