What’s wrong with an old man who can’t control his steps when he walks faster and faster?

Elderly people walking faster and faster can not control the footsteps may be caused by Parkinson’s disease.
Parkinson’s disease in the early stage of the disease, manifested as walking on the affected side of the upper limb swing arm amplitude decreased or disappeared, lower limb drag. With the progress of the disease, the pace gradually become smaller and slower, start, turn when the gait disorder is particularly obvious, from the sitting position, lying down when getting up difficult. Sometimes, after taking a step, with a very small step faster and faster, can not stop in time, known as forward gait or panic gait.
In addition, Parkinson’s disease also has stationary tremor, muscle tone, motor retardation, sleep disorders, autonomic dysfunction, mood disorders and other manifestations.
If an elderly person suddenly walks faster and faster and can’t control his/her steps, he/she must pay attention to it and seek medical examination and treatment in time.
