Stroke's Unbalancing Act: Understanding The Impact On The Body

A stroke can cause balance issues, which can put you at risk of falling and injuring yourself. Balance relies on information from different parts of the body, including eyesight, the balance organs in the ears, and messages about how the body is positioned. A stroke can cause problems if it affects any of the parts of the brain that receive or process these signals. Depending on the affected areas, you could experience issues such as vertigo, reduced sensation on one side of your body, or difficulty feeling how your body is positioned.

A stroke can cause weakness on one side of the body, making it difficult to balance

Balance requires coordination from both sides of the body. So, when a stroke causes weakness on one side, it can lead to impaired balance. This can manifest as difficulty sitting up or standing, or challenges with walking and moving the feet. The loss of balance can increase the risk of falling and subsequent injuries, which can significantly impact daily life and overall wellbeing.

It is important to seek medical advice and work with healthcare professionals to address balance problems after a stroke. Physiotherapy, balance retraining exercises, and the use of assistive devices can all play a role in improving balance and reducing the risk of falls. With the right support and rehabilitation, it is possible to regain balance and improve overall recovery outcomes.

Loss of sensation in the legs can make it difficult to know how to move, increasing the risk of falls

A stroke can cause loss of sensation in the legs, making it difficult for the person to know how to move their legs. This increases the risk of falls as the person has to rely more on their vision to compensate for the loss of sensation. This requires a lot of concentration, which can be tiring and make the person less aware of their surroundings.

Balance requires coordination from both sides of the body. A stroke usually affects either the left or right hemisphere of the brain while leaving the other side undamaged. This results in motor difficulties on the opposite side of the body, such as weakness or paralysis. Since balance requires coordination from both sides of the body, survivors with motor difficulties often experience impaired balance.

In addition to motor functions, the sensory systems also play a vital role in maintaining balance. Changes in a person's vision, sensation, vestibular system (sense of head motion and spatial orientation), and proprioception (sense of where the body is positioned in space) after a stroke can all impact their balance.

Poor balance puts stroke survivors at a greater risk of falling, which can lead to further injuries and complications. Many therapists prioritize balance therapy during inpatient and outpatient rehabilitation to help reduce the risk of falls and improve the patient's independence.

There are several effective interventions that can help stroke survivors regain their balance. Consistent rehabilitative exercises that improve strength and coordination in the legs and core muscles can result in improved balance. Addressing foot drop, a common condition following a stroke that impairs the ability to lift the front portion of the foot, can also help improve balance and reduce the likelihood of falling.

Virtual reality training programs and aquatic therapy are also effective methods for improving balance in stroke survivors. These therapies provide a safe and engaging environment for patients to practice balance exercises and improve their overall stability.

Vision problems are common after a stroke and can affect balance

Vision problems are very common after a stroke, with around two-thirds of stroke survivors experiencing some form of visual impairment. The type of vision problem will depend on the location of the stroke, but can include issues such as visual field loss, eye movement problems, and visual processing problems.

Visual field loss is the loss of part of the field of vision, usually affecting one side in each eye. This is called hemianopia and is the most common type of visual field loss following a stroke. With hemianopia, a person may feel like they are unable to see out of one eye, but in fact, both eyes are affected. This can make reading difficult, as words and sentences disappear when they fall in the missing part of the visual field.

Eye movement problems can affect the nerve control of the muscles that move the eyes. This may impact the eyes' ability to move between objects or to follow a moving object. It can also cause blurred or double vision if the nerve control to the eye muscles is affected.

Visual processing problems can cause issues with recognising objects or people by sight, or with recognising colours. It can also cause difficulty in reaching for objects and affect a person's ability to see more than one object at a time.

These vision problems can impact a person's balance, as vision is an important part of maintaining balance. If a person cannot see clearly, they may bump into things or stumble. They may also be at a higher risk of falls, especially in the first six months after a stroke when symptoms affecting balance, coordination, and vision are usually at their worst.

To improve balance and reduce the risk of falls, a person can work with a physiotherapist to improve their movement and stability. Balance retraining exercises can help improve their sense of balance and safely practice activities that they find difficult, such as standing, sitting, or changing direction while walking. Using a walking stick or cane can also improve stability and reduce the risk of falling.

Concentration problems can make it harder to move around and keep balance

A stroke can cause balance issues, which can put you at risk of falling and injuring yourself. This is because a stroke can change the way your brain controls balance, causing you to feel unsteady or uncoordinated. Concentration problems can also occur after a stroke, and these can make it harder to move around and keep your balance.

After a stroke, you may find that moving around and keeping your balance requires more concentration than it did before. This can be tiring and affect your ability to perform everyday activities. For example, you might find that you need to stop walking if you want to listen or talk. Other challenging situations include being in a busy environment, being on an uneven surface, or needing to make sudden changes in direction.

Vision is an important part of balance, and vision problems are common after a stroke. These can include difficulty focusing, double vision, and eye movement problems. If you are unable to see clearly around you, it can be harder to make the quick adjustments to your posture and movements to maintain your balance.

In addition to vision problems, stroke survivors often experience weakness on one side of their body, which can also contribute to balance issues. This weakness can make it difficult to sit up or stand, and can affect your gait, making you more likely to trip or fall.

To improve balance and coordination after a stroke, physiotherapy and balance retraining exercises are often recommended. These exercises can help to improve your sense of balance and allow you to safely practice activities that you are finding difficult. Equipment such as canes can also assist with balance when needed.

In summary, concentration problems after a stroke can make it harder to move around and keep your balance. This is because moving and balancing require a lot of concentration, and dealing with any situation that needs concentration can affect your balance. Additionally, vision problems and weakness on one side of the body, which are common after a stroke, can further contribute to balance issues. Physiotherapy, balance retraining exercises, and assistive devices can help improve balance and coordination.

Side effects of medication can include dizziness or weakness, impacting balance

A stroke can cause a person to lose their balance, and this is one of the ways in which a stroke can be recognised. A stroke occurs when there is a disruption in the blood flow to a part of the brain, and this can cause damage to brain cells and tissue.

A stroke can change the way the brain controls balance, and this can manifest as a weakness on one side of the body, making it difficult to balance. This can cause difficulty in sitting up or standing, and can lead to a condition called foot drop, where a person cannot lift their toes enough to stop them from catching on the ground when walking. This can make a person feel unsteady and more prone to tripping.

Vision problems are also common after a stroke and can contribute to balance issues. These can include double vision, eye movement problems, and difficulty focusing.

In addition to the direct effects of a stroke, the side effects of medication can also cause dizziness or weakness, impacting balance. Some medications commonly prescribed after a stroke, such as high blood pressure medication, can cause dizziness or weakness. It is important to note that withdrawal from antidepressants can also lead to dizziness. Interactions between different medications can also affect balance. Therefore, it is crucial to consult a doctor or pharmacist if you have any concerns about your medication. They may suggest trying new drugs or adjusting the combination of drugs to minimise these side effects.
