Improve Balance After Stroke

Balance: Steady as You Go

afterstroke1-novblog-banner

In today’s culture, it seems that we are always in search of the elusive life balance. But when a person survives a stroke, the word balance goes much further than simply finding an equilibrium between work and life: it takes on a very direct, literal, and physical meaning.

Balance impairment tends to be a pronounced and concerning complication, and has been found to affect 83% of people with stroke. So what does balance mean? The verb form of the word balance is usually defined as “to keep or put something in a steady position so that it does not fall,” and the noun form means “an even distribution of weight enabling someone or something to remain upright and steady”.

This definition also brings to light another distinct and prevalent concern among stroke survivors: falling. Although there may be many different contributing factors to falls in older adults (and especially those who have experienced a stroke), the balance impairment that comes with reduced sensory and motor abilities after stroke is thought to be one major cause. Unfortunately, it is also thought that problems with balance and mobility after a stroke may cause a higher fear of falling. Often a fear of falling is connected to avoidance: avoiding activities that were once very meaningful in order to avoid falling. As you can probably guess, this can then affect quality of life!

Types of Balance

Before we share some strategies for improving your balance, let’s talk about some differences in types of balance that may affect you.

  • Sitting balance: your ability to keep yourself steady while accomplishing a task from a seated position (in a chair, wheelchair, or at the edge of the bed, for example)
  • Standing balance: your ability to keep yourself upright while accomplishing tasks while up on your feet
  • Static balance: keeping control of your upright position while not moving around (for example, sitting on a stool at the counter waiting for the coffee to brew, or standing still holding a walker while looking into the closet for your clothes)
  • Dynamic balance: maintaining steadiness while body parts are in motion/changing position (for example, keeping steady while bending to load dishes into the dishwasher, or controlling your body while sitting and putting on your socks)

 

Your body’s needs for postural control can change frequently throughout a given task, requiring you to change from sitting to standing, or from static to more dynamic stability, depending on the demands of each activity you are trying to accomplish.

For example, you may start off your day sitting in a static position on the edge of your bed while you open your eyes and think about the day ahead. While you reach toward the ground to grab and put on your slippers, your sitting balance becomes dynamic. When you stand to look out the window at the weather, you are more static, and then when you reach into the closet and shift your weight to put on your robe, your standing balance becomes more dynamic. It is important to address all types of balance so that you have more control over your position and maximise your safety throughout all of the day’s tasks.

Factors that Affect Balance

When it comes to stroke, a lot of factors can affect sitting and standing balance. Here are some of the most common reasons:

  • Hemiparesis (weakness on one side of the body)
  • Decreased control of the trunk (the middle section of your body)
  • Altered weight distribution patterns when sitting/standing related to weakness
  • Impaired vision
  • Decreased attention/focus
  • Decreased sensation in the affected leg (and arm)
  • Decreased proprioception (awareness of the position/movement of a body part)
  • Decreased range of motion in the affected limbs/trunk
  • Impaired reflexes/reactions to sudden movement or position changes
  • Increased fear/anxiety related to possibly falling

What Can You Do to Help?

First of all, remember that each individual person is different and experiences stroke and stroke recovery differently! One of the most important things to do first is to figure out which factors seem to be the most obvious ones affecting your balance, so that those can be dealt with. Some research shows that most often weakness and sensation deficits have the greatest impact on balance. However, one person may have weakness and vision deficits, while another may have impaired reflexes and have trouble feeling the ground with their feet (and many more combinations!)

There are many options for you to work on balance. Keep in mind, many of these can help with balance in general – not just balance after a stroke!

1) Strengthening

Because a lot of balance difficulties are related to weaker muscles (in the legs, arms, and trunk), working to improve muscle strength can help. The stronger the muscles, the more control they have in keeping you upright. This doesn’t necessarily mean you need to join a gym if that’s not in your comfort zone!

Strengthening can be accomplished in several ways: completing your home exercise program and/or weight bearing activities suggested by your therapist, working on increasing your activity tolerance by gradually progressing the amount of time you spend doing everyday tasks (especially while you are standing up), and participating in group exercise classes that include agility and weight shifting. These options can help improve functional balance, mobility, and reflexes which can also help with fall prevention after a stroke. The CDC has noted that increasing physical activity helps to decrease the risk of falls, in large part related to improving balance.

2) Concentrating

Sometimes simply taking a deep, slow breath and truly focusing on a task can improve balance during that task. Often, we pay attention to too many details and try to multitask. Or we get distracted by too much information!

While this can easily happen to anyone, it can have more serious consequences after a stroke because other factors (such as weakness) come into play. With increased concentration often comes better preparation while approaching a task, and better focus on the particular balance skills needed for that given task.

3) Moving slowly

Along with concentration, a slower pace during a given task can improve the ability to remain balanced. With hasty, more abrupt motions, the body has less time to react and adapt the posture that is necessary to stay upright. By moving slower, you can “check” yourself more frequently and make sure that you aren’t starting to lean too far. In cases where your sensation is impaired and you can’t quite feel how your feet are positioned on the ground, moving slower will allow you to have more time to use other senses (such as vision) to check yourself.

4) Improving base of support

Your base of support refers to your body’s points of contact with the ground surface beneath you. After a stroke, it is more important than ever to be aware of how your feet are positioned while you are standing, reaching, stepping, turning, and just generally performing everyday tasks.

If your foot positioning changes so that your base of support is smaller, this could reduce your balance greatly. Examples of less-safe positions are: feet too close together, one foot in front of the other, feet twisted in different angles, or standing on one foot (even briefly) while shifting your weight during an activity.

Before performing a task, get in the habit of doing a quick check of your feet to see that they are at least shoulder-width apart, with your toes pointing forward. This may mean that you have to step closer to an object (like a cabinet!) while you are doing an activity.

5) Try Yoga

The practice of yoga promotes improvements in strength, muscle tone, flexibility, breathing patterns, reaction speed, and concentration. It can be modified based on skill level and safety/positional need (standing or sitting), and can be taught at a one to one level, or in groups. It is relatively easy to teach and perform, and research has shown that yoga intervention has improved balance scores in post-stroke patients.
