Description

Trigger Finger Prevention Game Interface Using EMG Sensor}

The present invention relates to a trigger finger resin prevention game interface device using an EMG sensor, and more particularly, an electromyogram capable of preventing trigger finger resin using a program linked to a Bluetooth module by attaching a bio patch to the back of a hand and receiving a bio-signal received from the EMG sensor. It relates to a trigger balance prevention game interface device using a sensor.

Usually, the most used part in daily life is the finger part from the wrist to the tip of the finger most.

Abnormal conditions such as stroke, multiple arteriosclerosis, brain injury, cerebral palsy, neurological disorder, polio, spinal injury, the elderly, and SCI disorders due to traffic accidents (injury, weakness, paralysis, etc.) or If rheumatoid arthritis due to decreased immunity occurs, a reasonable initial treatment method according to the cause of the occurrence will be applied, but in the case of the finger joint of the finger joint, external deformation of the bone from the metacarpal bone, which is the finger bone to the end of the finger, is It can occur, and it is applied in two main ways, such as drug therapy and physical therapy.

For example, in the case of finger rheumatoid arthritis, if continuous finger finger muscles and joint movement are not accompanied, the cartilage of the joint continues to harden and eventually the joint hardens, resulting in externally deformed fingers.

As a result, the need for rehabilitation exercises is more important than anything else, as muscles can also contract and degenerate, resulting in a permanent irrecoverable state along with depression and complications.

However, the form of rehabilitation exercise and treatment for finger finger handheld patients carried out by medical institutions or other institutions relies on drugs such as antibiotics and immunosuppressants, or simply causes a problem of inferior treatment and rehabilitation efficiency for the period due to the form of physical therapy.

Existing finger joint rehabilitation and treatment devices have been applied by simple methods such as hot/cold treatment of the entire finger. It has also been pointed out as a problem that it has certain limitations in improving the rehabilitation efficiency and additional properties that are higher than the cost.

Trigger resin (finger) is a phenomenon that occurs because a nodule or swelling occurs in the tendon of the finger flexing, or the A1 pulley located on the palm of the hand spine bone becomes thick, and the tendon passes under the A1 pulley.

It is a disease in which the tendon passes through the lesion area when the finger is moved and it is difficult to move due to severe friction or pain, and then suddenly a sound is made and the finger is not bent or stretched.

The cause of the trigger finger (finger) is usually idiopathic, where no specific cause can be detected. Usually, it appears in people who work while keeping their fingers bent for a long time, or who have a job that holds a handlebar or a steering wheel in their hands for a long time.It is caused by repeated palm friction due to an exercise that holds a racket such as golf. It is also possible.

In addition, secondary trigger resins may occur due to diabetes, gout, kidney disease, rheumatoid arthritis, and nodules.

Treatment methods for this disease include taking nonsteroidal anti-inflammatory analgesics or applying anti-inflammatory analgesics, and injecting steroids into the tendon membrane along with local anesthetics to obtain a short-term effect.

However, in the case of steroid injection, the pain may be severe immediately after injection, and infection may occur at the injection site. If injection is frequently given, discoloration of the surrounding skin, atrophy of the subcutaneous fat, and rupture of the tendon may occur.

It is performed when the effect of steroid injection for witchcraft treatment is not satisfactory or recurred, when symptoms persist for more than 9 months, or when finger locking occurs. Complications during surgery include infection and nerve damage.

Resin stiffness, which causes the fingers to harden after surgery, can be prevented by exercising the fingers immediately after the surgery.

There is no specific preventive method known to prevent the trigger finger, and it is helpful to make the hand flexible by simply holding the hand lightly and stretching the blood.

The hand is a body organ that is essential for receiving various sensory information in everyday life and performing the most sophisticated movements to perform interactions and play activities in the environment and independent life.

Therefore, if a disease such as a trigger resin persists and the hand function is deteriorated, basic self-help activities cannot be performed on their own, making independent life difficult.

In the treatment of the trigger resin, medication and physical therapy using anti-inflammatory analgesics are in progress, and a shock wave called an extracorporeal shock wave is generated while repeatedly receiving steroid injections, and the treatment is performed using a technology that helps remodel tissues and ligaments around the body.

However, there is no special way to prevent the trigger resin, so the majority of people who have jobs that work under tension by bending their fingers for long periods of time have a trigger resin.

Simple stretching has been suggested as a preventive method, but there is a problem that the patient can feel boredom for simple repetitive movements to perform the preventive treatment alone, the treatment effect is slow, and the voluntary treatment performance is poor.

In addition, when a patient moves to a hospital and moves to a hospital with a rehabilitation (prevention) device and a rehabilitation therapist to receive treatment, there is a disadvantage that a long wait is required.

In view of this, the present invention is a trigger resin with a high probability of developing in a profession that requires working with a finger bent in a tense state for a long time, a job that holds a cook, a handlebar, a steering wheel, etc. in the hand for a long time, or repeatedly Efforts have been made in the form of a game to provide a means for people with a job that must touch a working machine to prevent the trigger balance.
