Parkinson’s instability

One of the most important signs of Parkinson’s is postural instability, a tendency to be unstable when standing upright. A person with postural instability has lost some of the reflexes needed for maintaining an upright posture, and may topple backwards if jostled even slightly. Some develop a dangerous tendency to sway backwards when rising from a chair, standing or turning. This problem is called retropulsion and may result in a backwards fall. People with balance problems may have particular difficulty when pivoting or making turns or quick movements.

Doctors test postural stability by using the “pull test.” During this test, the neurologist gives a moderately forceful backwards tug on the standing individual and observes how well the person recovers. The normal response is a quick backwards step to prevent a fall; but many people with Parkinson’s are unable to recover, and would tumble backwards if the neurologist were not right there to catch him or her.

Parkinson’s Progression

The progression of Parkinson’s disease varies among different individuals.  Parkinson’s is chronic and slowly progressive, meaning that symptoms continue and worsen over a period of years.  Parkinson’s is not considered a fatal disease. And the way that it progresses is different for everyone:

• Movement symptoms vary from person to person, and so does the rate at which they progress.
• Some are more bothersome than others depending on what a person normally does during the day.
• Some people with Parkinson’s live with mild symptoms for many years, whereas others develop movement difficulties more quickly.
• Nonmotor symptoms also are very individualized, and they affect most people with Parkinson’s at all stages of disease.  Some people with Parkinson’s find that symptoms such as depression or fatigue interfere more with daily life than do problems with movement.
