Writing cramps

Writing spasm, also known as primary writing tremor, is the most common action tremor in adults, especially when writing tremors, making writing difficulties the most common. This disease is more common clinically, and refers to patients who experience hand tremor at 5 to 8 Hz during writing or writing, without any other dysfunction. In some patients, tremor is not limited to writing, but tremor may also occur when doing similar work or using similar tools. Therefore, it has been proposed that writing spasticity can be divided into task-induced writing spasticity and posture-sensitive writing spasticity.
