Wrist hooking means hooking the hand inward when writing. Prolonged wrist hooking can cause wrist twisting, finger developmental deformities, spinal developmental disorders and other hazards, leading to carpal tunnel syndrome, finger fasciitis, cervical spondylosis and other diseases.
1. Carpal Tunnel Syndrome: Due to prolonged forceful use of the wrist, it can lead to carpal tunnel syndrome, resulting in pain and numbness of the hand and wrist.
2. Finger fasciitis: Finger fasciitis can occur due to improper finger exertion and overwork, resulting in symptoms such as finger pain, muscle tension, and restricted movement.
3. Cervical spondylosis: due to the bad posture of writing and hooking the wrist, it can lead to cervical spondylosis in the long run.
In addition, this writing method violates the general law of writing force, thus making the writing of the pen stiff, writing too small and twisted, writing efficiency is low. Therefore, it is necessary to strictly correct the habit of writing with a hooked hand and cultivate the correct posture of holding the pen.
