Postural Instability: Everything You Need to Know
Do you know what postural instability is? If not, don’t worry, you’re not alone. Postural instability is a term used to describe the inability of an individual to maintain balance while in a stationary position. This can be caused by various factors, such as muscle weakness, joint pain, and poor coordination.
What is postural instability?
- Muscle weakness
- Joint pain
- Poor coordination
Postural instability can make it difficult for people to stand for long periods or walk without support. In some cases, it can also lead to falls.
What is postural instability a significant cause of?
There are many causes of postural instability, but the most common cause is muscle weakness.
There are many causes of postural instability, but the most common cause is muscle weakness. This can be caused by various conditions, such as:
- Diseases that affect the nervous system (such as
- Parkinson’s disease)
- Muscular dystrophy
- Multiple sclerosis
- Cerebral palsy
- Stroke
- Amputation
- Arthritis
Another common cause of postural instability is joint pain. Joint pain can be caused by conditions such as:
- Osteoarthritis
- Rheumatoid arthritis
- Ankle sprains
- Foot problems (such as bunions or flat feet)
- Knee problems (such as a torn meniscus)
Postural instability can also be caused by poor coordination. This can be caused by:
- Diseases that affect the nervous system (such as
- Parkinson’s disease)
- Stroke
- Cerebral palsy
- Amputation
- Brain injury
Parkinson's Disease and Postural Instability
Parkinson’s disease is a neurological disorder that affects the nervous system. This can lead to muscle weakness, joint pain, and poor coordination.
People with Parkinson’s disease often have difficulty standing or walking without support. Treatment options for Parkinson’s disease include medication, surgery, and physical therapy.
What are motor symptoms associated with postural instability?
There are many motor symptoms associated with postural instability, such as:
- Tremors: This is a common symptom of Parkinson’s disease. It can cause muscle weakness and difficulty standing or walking.
- Rigidity: This is also a common symptom of
- Parkinson’s disease. It can cause joint pain and stiffness.
- Bradykinesia: This is another common symptom of Parkinson’s disease. It refers to the slowness of movement. People with bradykinesia often have difficulty performing everyday tasks, such as getting dressed or brushing their teeth.
- Dystonia: This is a condition that causes muscle spasms. It can lead to joint pain and difficulty moving.
- Ataxia: This is a condition that affects coordination. People with ataxia often have difficulty walking and may stumble or fall.
What are the symptoms of postural instability?
The symptoms of postural instability vary depending on the underlying cause. However, some common symptoms include:
- Muscle weakness
- Joint pain
- Poor coordination
- Fatigue
- Dizziness
- Light headedness
- Nausea
- Fainting
If you experience any of these symptoms, it’s important to see a doctor so they can determine the underlying cause. In addition, instability may be a symptom of another condition, so it’s essential to get an accurate diagnosis.
What is severe postural instability?
Severe postural instability is a medical emergency that can lead to falls and injuries. If you experience any of the following symptoms, it’s essential to seek medical attention immediately:
- Unsteadiness while standing or walking
- Sudden falls
- Inability to stand or walk without support
- Loss of consciousness
- Paralysis
While there are many minor reasons why this may occur, these symptoms can be caused by conditions such as stroke or a brain injury. Therefore, if you experience any of these symptoms, it’s essential to seek medical attention immediately.
How can you test for postural instability?
There are a few different ways to test for postural instability. Depending on your presenting condition your therapist may pursue a range of different tests.
The Retropulsion Test
The retropulsion test is considered the most effective technique to assess postural instability. A common variant involves having the person stand close to a wall and then push off the wall with their hands. The test is positive if the person falls backwards or has to take a step back to maintain balance.
Timed Up and Go Test (TUG).
This test involves having the person stand up from a chair, walk a short distance, turn around, walk back to the chair, and sit down. The time it takes to complete this task is then recorded.
Postural Instability and Gait Abnormalities (PIGA) scale.
This scale measures things like balance, gait, and ability to turn. It is often used in people with Parkinson’s disease.
Berg Balance Scale (BBS).
This scale measures balance and is often used in people with Parkinson’s disease.
Tinetti Performance-Oriented Mobility Assessment (POMA).
This scale measures things like balance, gait, and ability to turn. It can be used in people with a variety of conditions.
How is postural instability treated?
Treatment depends on the underlying cause.
If the reason is muscle weakness, treatment may involve:
- Physical therapy: This can help improve muscle strength and coordination.
- Exercise: This can help improve balance and prevent falls.
- Assistive devices: These can help people with stability issues walk more safely. Common devices include a cane, walker, or wheelchair.
If the cause is joint pain, treatment may involve:
- Pain medication
- Anti-inflammatory medication
- Physical therapy
- Exercise
- Surgery
If the cause is poor coordination, treatment may involve:
- Occupational therapy
- Physical therapy
- Exercise
- Surgery
Working towards Postural Stability
Postural and movement instability can make everyday activities a challenge.
From something as simple as getting out of bed in the morning to walking to the mailbox, postural instability can make daily tasks difficult and dangerous.
In addition, stability issues are often caused by other condition, such as muscle weakness, joint pain, or poor coordination. Treatments available can help improve postural stability and quality of life.
Finally
Postural instability can be a debilitating condition, but there are treatments available that can help. If you think you may have instability, it’s important to see a doctor or other recognized health care provider so they can properly diagnose and treat the underlying condition. With the right treatment plan in place, you can work towards achieving better postural stability and improving your quality of life.
