ESSENTIALS OF STROKE ASSESSMENT: HOW PHYSIOTHERAPY CAN HELP

Cardiovascular diseases are the second leading cause of morbidity and mortality in Kenya, one of them being stroke; from paralysis to coordination issues to muscle weakness, the physical after-effects of stroke can be devastating.

However, physiotherapy offers numerous benefits for stroke survivors. Working with a trained physiotherapist can help you to regain functionality, strengthen muscles, reduce pain, and regain your quality of life over time.

What is a Stroke?

A stroke occurs when the blood supply to part of your brain is interrupted or reduced, preventing brain tissue from getting oxygen and nutrients. Brain cells begin to die in minutes. Every second of every day, your heart pumps nourishing, oxygen-rich blood through a vast network of blood vessels all throughout your body, with a whopping 20% of that blood and oxygen heading towards the brain. When that flow of blood to your brain is interrupted, the result is a stroke. Brain cells die quickly when their blood supply is cut off, which leads to the lasting effects of a stroke.

Types of stroke:

1. Ischaemic Stroke. Comprising 85% of all strokes, ischaemic events occur when blood flow is cut off from the brain. This is usually caused by a blood clot that originates in the brain itself or travels to the brain from another part of the body. The areas of the brain supplied by the clogged vessels are at risk of impairment as brain cells die. This can happen when there is buildup of fats, cholesterol and other substances in and on your artery walls (plaque), restricting blood flow (Atherosclerosis).
2. Haemorrhagic Stokes. Though rarer, haemorrhagic strokes are often more severe. They’re caused by a ruptured blood vessel either inside the brain or on the brain’s surface. When blood vessels burst, the leaked blood creates pressure and swelling that’s damaging to nearby brain cells; the damaged area is unable to function properly. a. Intracerebral hemorrhage: The bleeding occurs inside of the brain. This is the most common type of hemorrhagic stroke

b. Subarachnoid hemorrhage: The bleeding occurs between the brain and the membranes that cover it.

• Transient Ischaemic Attacks (TIA). Known to some as a mini-stroke, a TIA is characterized by a stroke whose symptoms last 24 hours or less. Although they don’t last as long as other strokes, people who have TIA’s are more likely to have a full stroke in the near future.

The Physical Effects of Stroke

After a stroke, many people are left with a combination of psychological, cognitive, and physical effects. From a psychological perspective, survivors may feel an increase in anxiety or depression. Cognitively, there may be issues in memory, concentration, and understanding. Survivors may also have trouble swallowing, reading, writing, vision, and speaking.

When it comes to your physical health, strokes can have a variety of effects on your movement and senses:

• Movement & Balance. Issues like muscle spasticity, weakness, paralysis, and balance problems can severely impact stroke survivors’ ability to walk, run, stand, drive, and complete other ordinary daily movements. 

• Hemiparesis. Eight out of ten stroke survivors experience weakness in one side of their body. This can cause a variety of issues with coordination, muscle fatigue, difficulty walking, and trouble performing regular self-care activities.

• Paralysis. Following a stroke, around 90% of survivors will experience some paralysis, which means being unable to move a group of muscles. Even years after a stroke, physiotherapy can help stroke survivors regain some movement. 

• Foot drop. Some people might experience foot drop after a stroke, which is when damaged nerves make it difficult to raise the front part of your foot. 

• Pain. More than 50% of stroke survivors experience pain after a stroke. This can be especially prevalent in the shoulder joint. Because strokes change your ability to perceive sensation, you may experience central post-stroke pain (CPSP), which happens when your brain interprets non-painful stimuli (like touch or warmth) as painful.

The Essentials of Stroke Assessment 

As soon as 24 hours following a stroke, physiotherapists help stroke survivors with sitting up, getting out of bed, standing, and walking. Sometimes, your team will help you regain the ability to walk using devices like a treadmill. This acute physiotherapy treatment is an important first step, but your acute care will soon transition to rehabilitative care as you leave the hospital. 

Before you begin rehabilitation, you’ll need a stroke assessment from a professional physiotherapist:

 Interview & Observation

A physiotherapy team needs to know some basic facts about the patient before they create any treatment plan. Example; How old are you? How much physical activity did you do regularly before your stroke? And what are your treatment goals?

In addition, your physiotherapist will want to know if you are living and working in an environment that supports your rehabilitative goals. Is your home safe and easily accessible? Do you have family available to help you throughout rehabilitation? Are you using a wheelchair or a brace in your everyday life?

This is a great time to tell your physiotherapist how you feel, physically. At the same time, your physiotherapist will observe you as you perform regular motions like sit, stand, grip items, and walk across the room. They’ll pay attention to your posture and take note of any issues they detect in your gait or motion.

Assessments:

These include;Mobility, Muscle strength, Movement, and More.

Every physiotherapist relies on specific tests to see how your muscles, joints, and nerves are working. For example, they might see how different areas of your body respond to sensation, especially if you’ve reported any unusual pain or numbness.

A physiotherapist will probably test your reflexes, assess your muscle strength, and check the mobility of your joints. While they administer these simple, easy tests, they’ll be actively assessing the following for any impairments:

• Balance. Can you maintain your balance while sitting and standing?

• Coordination. Are you able to use different muscles and parts of your body smoothly and accurately?

• Muscle Strength. Is one side of your body stronger than the other? Do you lack grip strength or leg strength?

• Muscle tone. Are any of your muscles lacking muscle tone, or have so much tone that you are experiencing spasms?

• Function. Can you perform everyday activities efficiently, such as using the bathroom, walking up stairs, and transferring items from hand to hand?

• Mobility. Do you have difficulty walking around, standing up, or using the stairs?

• Sensations. Do you have difficulty telling sensations apart? Do sensations like touch and temperature cause you pain?

• Range of Motion. Do any of your joints have an inhibited range of motion?

• Posture. Are you in alignment when you stand, sit, and walk?

Treatment plan:

Any physiotherapist has a goal setting or a treatment plan after analyzing the patient’s problem or diagnosis. This will help the therapist come up with the best treating techniques that will help him/her achieve great results after the treatment session.

Together, you and your physiotherapist will come up with rehabilitation goals which will vary based on your unique situation. For example, if you have drop foot, your goal might be to work on strengthening the muscles and joints in your foot to regain function. If you have difficulty with balance, you and your physiotherapist will use various balancing and postural exercises to help you reach your goals.

Benefits of Physiotherapy After Stroke

Its best to start physiotherapy immediately following a cerebrovascular accident, treatment can make a huge difference even if started years after a stroke. 

This treatment should continue as long as necessary, we recommend survivors to do physical therapy five days a week, 45 minutes per day.

With an incredible diversity of techniques and tools; exercise, massage, joint mobilisation, muscle stretching, and beyond, a physiotherapist can help get you on the road to rehabilitation. Though your goals and treatment plan will vary based on your unique situation, the benefits of physiotherapy after a stroke look something like this:

• Fall prevention. 55% to 73% of people experience a fall in the year after having a stroke. Physiotherapists can help you get fitted for a necessary brace to support your stability, help strengthen any weak leg muscles that contribute to falls, and help you regain your balance through balancing exercises.

• Improve Muscle strength. After a stroke, you might find that some of your muscles are weaker than they used to be, which limits your activities. Your physiotherapist can help you retrain these muscles through repetitive movements and practice. In some cases, electric currents may be used to help stimulate the muscle.

• Reduce Stiffness and pain. Shoulder pain, muscle spasms, and painful contractures are common after a stroke. Using a variety of techniques, including passive movement, active movement, and positioning, your physiotherapist gently helps to stretch your muscles and move your joints.

• Regain functional use. As part of your goal-setting, you and your physiotherapist will work toward your ideal functionality, one step at a time. For many stroke survivors, this means re-training on how to use an unused limb like a hand or a leg. For example, by gently restraining a functioning left arm, your physiotherapist can help you regain movement in your lesser-used right arm.

• Helps reduce the risk of stroke. Though you’ll receive a lot of guidance in-office, your physiotherapist will also provide you with at-home exercises that will help strengthen muscles, keep joints flexible, and regain function. In addition, incorporating physical activity in your lifestyle can help reduce your risk of a future stroke by 35%.

• Improve movement and mobility. By working with you on any gait abnormalities, your team will help you improve your ability to walk and move independently.

• Regain sensory awareness. Strokes can change the way we process sensory inputs like touch and temperature. Simple sensory stimulation exercises like stroking and tapping can help you recognize sensations and regain functionality.
