Description

A writing assisting device for Parkinson's patients

Technical field

The invention belongs to the technical field of writing aids, and in particular relates to a writing aid for Parkinson's patients.

Background technique

Parkinson’s disease (Parkinson’s disease, PD) is a common neurodegenerative disease. It is more common in the elderly, with an average age of onset of about 60 years old. Parkinson’s disease is less common in young people under 40 years of age. The prevalence of PD in people over 65 years of age in my country is about 1.7%. Most PD patients are sporadic cases, and less than 10% of patients have a family history. The main pathological change of Parkinson's disease is the degeneration and death of dopaminergic neurons in the substantia nigra of the brain, which causes a significant decrease in striatal dopamine content and causes disease. The exact cause of this pathological change is still unclear. Genetic factors, environmental factors, aging, oxidative stress, etc. may be involved in the degeneration and death of PD dopaminergic neurons. PD has an insidious onset and progresses slowly. The first symptom is usually tremor or clumsiness in one limb, which affects the opposite limb. The main clinical manifestations are static tremor, bradykinesia, muscle rigidity and postural and gait disorders. The existing writing assisting device is not suitable for PD patients, it is inconvenient to adjust the angle of the writing board and the height of the assisting device, and it is easy to cause fatigue of the back and arms of the PD patient, and affect the use of the PD patient.
