Nowadays, people generally use computers when working, and long-term use of computers can cause the generation of mouse hands. So how to prevent the generation of mouse hands? Let's take a look together.
Mouse hand, one of the most common diseases in modern society, is mainly caused by prolonged contact and use of computers. Due to long-term intensive, repetitive, and excessive activities, wrist joints cause paralysis, swelling, pain, and spasms in wrist muscles or joints, making this disease rapidly become an increasingly common modern civilized disease.
Clinically, some patients may experience atrophy of the "thenar" muscle under the thumb due to long-term pathological changes; Intermittent skin whitening and cyanosis may even occur; In severe cases, cyanosis of the thumb and index finger, necrosis of the fingertips, or atrophic ulcers can occur, becoming irreversible changes.
Carpal tunnel syndrome is common in women aged 30 to 50 years, five times as many as men. Bilateral morbidity accounts for about 1/3 to 1/2, and the ratio of female to male morbidity is 9:1. "Due to compression of the median nerve, pain and sensory numbness occur in the thumb, forefinger, and middle finger.". "Initially, it often manifests as sensory dysfunction at the fingertips, often resulting in numbness or burning pain several hours after falling asleep, which can be alleviated after activity.". Due to the longer course of disease, a few patients have neurotrophic disorders, atrophy of the thenar muscles, intermittent skin whitening, cyanosis, and in severe cases, cyanosis of the thumb and index finger, necrosis of the fingertips, or atrophic ulcers. During examination, it is possible to tap the palmar median of the wrist, causing numbness and pain in the innervated area of the median nerve, which is known as a positive Tinel sign. In some patients, the abnormal sensation of the fingers worsened after 60 seconds of extreme flexion of the wrist joint, which is positive for the Phalen test. Using a sphygmomanometer to pressurize the upper arm to dilate the distal limb veins can induce symptoms.
Acupoints: Neiguan, Daling, Yuji, and other acupoints, as well as the palmar side of the forearm, wrist, and hand.
Methods: Rolling, pressing, finger rubbing, shaking, wiping, holding, rubbing, etc.
1. First, apply the rolling method on the palmar side of the affected limb's forearm, wrist, and hand; The method of rolling up and down from the forearm to the palm of the hand focuses on the carpometacarpal and palmar parts, and cooperates with passive movement of wrist flexion and a small amount of passive movement of wrist ulnar and radial deviation. This treatment takes about 10 minutes.
2. Following the above postures, massage the Neiguan, Daling, and Yuji acupoints for 1 minute each. Among them, Daling acupoint is the main point, with emphasis on pressing and kneading, and appropriate coordination with small range flexion and extension movements of the wrist joint. The second is the thenar acupoint, which can also be kneaded, combined with the manipulation of Hegu, the manipulation of thenar muscles, and the manipulation of wrist and palm tendons. This treatment takes about 3-5 minutes.
3. Following the above posture, shake the wrist joint (up and down, clockwise, counterclockwise rotation), rub all fingers, mainly the thumb, forefinger, and middle finger. Finally, apply the rubbing method to the palmar side of the forearm, the palmar side of the wrist, and the greater thenar region.
Long term keyboard tapping, wrist numbness, massage required
The correct posture should be to relax the upper body, straighten the spine, and place the elbows at 90 to 100 degrees. This way, the wrist muscles are not easy to tense. When typing, pay attention to the angle of your wrist. It is recommended to place a rolled towel under your wrist so that your hands and wrists are as straight as possible.
In addition, posture such as hunching and shrugging is also not conducive to operation. At the same time, it is important to take a break and exercise your wrist every 1 hour of using the computer, and try not to work in the same posture for long periods of time. If the hand has tenderness or swelling, first rinse it with cold water to cool the affected part, then gently move the wrist up and down while gently massaging the forearm (wrist to elbow) muscles
With this knowledge, even those who often face the computer will easily stay away from the mouse hand, making your hand more beautiful.
