Recovering After A Stroke: Regaining Strength And Mobility

A stroke is a medical emergency that occurs when blood flow to the brain is interrupted. The recovery process is different for everyone and can take days, weeks, months, or even years. The recovery timeline depends on several factors, including the severity of the stroke, the area of the brain affected, and the individual's health before the stroke. Rehabilitation plays a crucial role in helping stroke survivors regain their physical and cognitive abilities, and it is important to start rehabilitation as soon as possible. This involves a team of specialists, including physiatrists, neurologists, physical and occupational therapists, speech-language pathologists, and nurses. The rehabilitation process focuses on improving movement, speech, swallowing, vision, and cognitive functions, as well as managing emotional and behavioural changes. While there is no quick fix for healing the brain, survivors can maximize their recovery potential by adhering to a consistent rehab plan, stimulating neuroplasticity, and focusing on consistent practice.

Consistent practice and repetition of therapeutic exercises are key to recovery

After a stroke, the brain can compensate for losses through various regenerative strategies, and one of the most common processes is neuroplasticity. This is the brain's ability to form new synapses or connections between neurons, especially in response to injury. The nervous system reorganizes the neurons that remain intact, and consistent repetition helps re-establish communication between the damaged parts of the brain and the body.

Repetition and Neuroplasticity

Neuroplasticity is the brain's way of healing itself. For our bodies to perform simple tasks, networks of neurons must work together to stimulate the correct parts. When a stroke damages an area of the brain, the neurons in that area can no longer send signals to the corresponding regions of the body. The brain compensates for these losses by restructuring synaptic pathways to work around the damaged neurons, and it can even relocate these pathways to entirely different areas of the brain.

The Role of Repetition

Through consistent repetition, the neurons involved in the process of neuroplasticity are stimulated. Research has shown that stroke survivors who use repetition to promote neuroplasticity make significant progress in their recovery. In one study, patients who initially struggled with grasp-and-release exercises demonstrated increased cortical reorganization when they followed a repetitive rehabilitation regimen.

Visualizing Progress

In addition to physical repetition, visualizing the exercises can also strengthen the involved synapses. In a 1995 study, participants who imagined completing a piano exercise showed strengthened synapses, even though they were not performing any physical motions. Visualization can be a great introduction to rehabilitation for those who are not yet able to perform the physical movements.

Challenging Yourself

Once a repetitive action is mastered, it is important to continue challenging yourself with more difficult exercises. This is against human nature, as we tend to feel that we have succeeded when a task becomes easy. However, repetitions on "autopilot" are far less beneficial than when the individual is actively focused on performing each repetition. It takes self-discipline to continue increasing the difficulty of an exercise, but you can derive motivation from the support of a therapist, friends, or family.

Mindfulness and Motivation

Mindfulness during practice ensures that the brain is fully present and supported for neuroplasticity. Visualization can also be motivating, pushing the person in rehabilitation past the plateau stage, a dispiriting time when progress stalls. Keeping exercises from becoming routine is key—when each day is challenging in a new way, the brain stays engaged in ways that are more conducive to synaptic rehabilitation.

Consistent Practice

Consistent, dedicated repetition is the most important priority for recovery. Without this, the brain cannot complete the rebuilding of the neurons, networks, and capabilities it lost during the stroke. Quality of repetitions is just as important as quantity, and remaining mindful and fully present during practice is essential.

Long-Term Recovery

Even after six months, when improvements become much slower, it is crucial to continue following up with your care team. Most stroke patients reach a relatively steady state at this point, but there is still hope for small advances. Improvement may take longer for some patients, but consistent practice and repetition of therapeutic exercises can facilitate further progress.

Gait improvement: focus on full-body exercises, not just the feet

Gait training and balance training are key components of post-stroke rehabilitation. These exercises can help you relearn how to walk, improve your balance and coordination, and increase the strength of your ankles, knees, and hips to support your body when you move.

• Side Stepping: This exercise increases glute activation and dynamic stability and balance with lateral weight shifting. Start by stepping to the side with one leg and then following with the other. Repeat several times and then change directions. Ensure that you are using support if needed. To progress this exercise, you can add resistance bands around your knees to increase glute activation.
• Forward to Backward Weight Shifting: This exercise improves foot clearance, pelvis stability, and standing balance with weight shifting. Start by taking a step forward with one foot, then lift that leg up and move it back behind your body. Repeat several times and then switch sides. Always use support to ensure stability. To increase the challenge, add ankle weights or try to maintain your balance without relying on arm support.
• Stepping Up: This exercise increases hip flexor strength, which improves foot clearance, step length, quadriceps strength, and glute strength for improved force generation and gait speed. It also improves pelvis stability and standing balance with weight shifting. Stand in front of a step and step up with one foot, followed by the other, and then step down. Repeat several times. To increase the challenge, try not to use arm support to maintain your balance and increase the step height.
• Seated to Standing: This exercise increases quadriceps and glute strength for improved stability and leg strength. Start by sitting in a chair and then lean forward, using your legs to stand up. Slowly lower yourself back into the chair without using your arms for support. To progress this exercise, add resistance bands around your knees to increase glute activation.
• Single-Leg Lift: This exercise increases hip flexor strength to improve foot clearance and increase single-leg strength and stability while standing and weight shifting. Begin seated in a chair and lift one leg up, hold for two seconds, and then lower. Repeat on the other side. For a standing variation, stand next to a stable object such as a chair or table for support and slowly lift one leg up. Hold for two seconds and then lower. Repeat on the other side. To increase the challenge, add ankle weights or try not to rely on arm support to maintain your balance.

These exercises can help improve your gait and overall mobility after a stroke. It is important to consult with a healthcare professional to determine the appropriate exercises and progressions for your specific needs and condition.

Speech therapy apps can aid language difficulties

Communication problems are common after a stroke, with around one-third of survivors experiencing difficulties with speaking, reading, writing, and understanding others. These issues can be incredibly frustrating, but they can improve with time and treatment.

A speech and language therapist can help stroke survivors improve their communication skills. They can teach exercises to strengthen mouth and tongue muscles and help patients and their families use tools like cue cards, pictures, and electronic devices to aid communication.

There are also many speech therapy apps available that can aid language difficulties. These can be used in conjunction with a trained clinician's feedback to help stroke survivors improve their language skills. Apps can be particularly useful for supporting student engagement and targeting communication skills.

For example, the SpeakEasy app offers activities, games, articles, and tracking to help children with language development. It is used by over 100,000 parents and speech therapists and has been shown to improve parent-child communication. The app is customizable and offers different journeys, including language, articulation, attention, and autism tracks.

There are also several apps designed specifically for adults with aphasia, a common language difficulty after a stroke. Tactus Therapy offers a range of apps that cover all levels of aphasia, including Language Therapy 4-in-1, Advanced Language Therapy, and Conversation Therapy. These apps can help with speaking, listening, reading, and writing, and can support communication strategies and independence.

Other apps that can aid language difficulties include:

• CoughDrop: an easy-to-use AAC (augmentative and alternative communication) program.
• Little Stories: an app with stories targeting speech sounds, reading fluency, comprehension, and conversation.
• Word Vault: an app offering stimuli for articulation, phonology, language, and social communication skills.
• Your Face Learning: an app that creates customized worksheets for students targeting sounds, basic concepts, story starters, and more.

Meditation can accelerate recovery and help with post-stroke depression

Meditation can be a powerful tool to aid in stroke recovery and help manage post-stroke depression. It can be daunting to start, but with the right tools, it can change your life. Meditation has the power to change the physiology of the brain, and with consistent practice, you can bring about these changes in a peaceful manner.

How Meditation Helps Stroke Recovery

Meditation can be a valuable addition to your stroke recovery plan. It can help you manage the stress and frustration that comes with the recovery process, both physically and mentally. Most rehabilitation methods require intense focus on a single activity, which can be mentally exhausting. Taking a few minutes each day to focus on your breath and relax your body and mind can do wonders for your overall well-being.

Research has shown that mindfulness meditation can have positive effects on post-stroke spasticity. Spasticity is a condition where muscles stiffen and interfere with movement. In a study conducted by Wathugala et al., 10 stroke survivors participated in a 2-week experiment where they listened to daily guided meditations. The results showed significant improvements in spasticity in the elbow and wrist, along with enhancements in quality of life measures for energy, personality, and work/productivity.

Getting Started with Meditation

Starting a meditation practice may seem challenging, but there are a few tips that can help you get started:

• Set Realistic Goals and Expectations: It's important to set realistic goals, such as meditating for 5 minutes, 4 times a week. Understand that your mind will wander, and that's completely normal. With consistent practice, you'll find it easier to redirect your attention back to the meditation.
• Create Daily Habits: Try pairing meditation with something you already do every day. For example, you could meditate right after breakfast or before bed. This will help you establish a routine and make it a smoother process.
• Use Guided Meditation Apps: You don't have to navigate meditation alone. There are many apps available that offer personalized guided meditations, such as Balance, Headspace, Calm, and Simple Habit. These apps can help you get started and provide a variety of meditation options.

By incorporating meditation into your stroke recovery plan, you can accelerate your recovery and manage any post-stroke depression or anxiety. Remember to be patient with yourself and consistent in your practice, and you'll soon start reaping the benefits of meditation.

A healthy diet, with foods that promote neurogenesis, can aid recovery

A healthy diet can be a key factor in stroke recovery. The process of neurogenesis, or the formation of new neurons, is critical for brain health and cognitive function. A healthy diet that promotes neurogenesis can aid in stroke recovery by improving brain plasticity, brain homeostasis, and the repair of damaged brain cells.

Neurogenesis is particularly important in the hippocampus, a brain structure associated with learning, memory, and mood. The hippocampus is one of the few regions in the adult brain where neurogenesis persists. By promoting neurogenesis in the hippocampus, certain dietary components can have beneficial effects on cognitive function and overall brain health.

Some of the key dietary components that have been shown to induce neurogenesis include:

• Curcumin: Found in turmeric and yellow curry spice, curcumin has been shown to increase neurogenesis in the hippocampus and improve cognitive performance.
• Resveratrol: Found in peanuts, tree nuts, grapes, cocoa, wine, and berries, resveratrol has neurogenic properties and can improve cognitive function.
• Blueberry polyphenols: Blueberries have been shown to increase neurogenesis and improve cognitive performance in both animals and humans.
• Omega-3 fatty acids: Found in fatty fish, walnuts, flaxseed, and their respective oils, omega-3 fatty acids are essential for brain structure and function. They have been linked to improved cognitive function and the prevention of cognitive decline.
• Polyunsaturated fatty acids (PUFAs): PUFAs have been shown to induce neurogenesis and combat neurodegenerative diseases and cognitive decline.
• Caloric restriction: Reducing calorie intake by 30-40% has been found to increase neurogenesis and improve spatial learning in rodents.

In addition to these specific dietary components, a generally healthy and balanced diet is important for overall health and can contribute to neurogenesis and stroke recovery. A diet rich in vitamins, nutrients, and antioxidants can provide the brain with the necessary building blocks for neurogenesis and support overall brain function.

It is important to note that individual responses to dietary changes may vary, and further research is needed to fully understand the complex interactions between diet and neurogenesis. However, adopting a healthy diet that includes neurogenesis-promoting foods can be a beneficial strategy to support stroke recovery and overall brain health.
