Stroke rehabilitation

Post-stroke arm paresis and epilepsy risks

Motor rehabilitation of patients who have suffered an ischemic stroke (ictus ischaemicus) often requires adjuvant (supporting) methods, especially in the presence of post-stroke arm paresis. The recovery process is associated with serious risks. In the post-stroke period, active synapse growth continues in the brain, and specific changes occur in the neurotransmitter system. These pathophysiological processes create a favorable environment for the development of acute symptomatic epileptic seizures.

The occurrence of seizures is extremely dangerous: they can significantly increase the volume of cytotoxic edema and expand the zone of ischemic brain tissue damage. Epidemiological data show that the cumulative risk of developing post-stroke epilepsy within ten years after a stroke reaches 30%. This condition significantly limits the potential for full rehabilitation and drastically reduces the patient's quality of life. Therefore, patient management tactics require careful clinical monitoring and the mandatory identification of high-risk groups.

Multifactorial nature of post-stroke pain syndrome

Pain is one of the main obstacles to motor recovery. The pathogenesis of post-stroke pain is multifactorial. Clinical practice distinguishes several main sources of pain:

• Local damage to periarticular tissues.
• Myogenic pain (e.g., scalene muscle spasm).
• Neuropathic pain, which may include complex regional pain syndrome.
• Specific central post-stroke pain.
• Pain directly related to muscle spasticity.

To objectify patient complaints and assess pain intensity, neurology standardizes the use of the Visual Analog Scale (VAS).

Pain management algorithms

Depending on the identified nature of the pain, a differentiated treatment approach is applied.

1. Injection methods: Include the administration of glucocorticoids (glucocorticoida) directly into the shoulder or subacromial joints. For the myogenic component, botulinum toxin type A (toxinum botulinicum) with or without hemagglutinin complex is injected into the subscapularis, pectoralis major, and other involved muscles. Suprascapular nerve block is also effective.
2. Physiotherapy and exercise therapy: Shoulder muscle electrical stimulation, therapeutic massage, gentle mobilization techniques, and acupuncture are prescribed.
3. Orthopedic and pharmacological support: Patients are indicated to wear specialized shoulder orthoses, while non-steroidal anti-inflammatory drugs (NSAIDs) and antirheumatic agents are used for systemic pain relief.

Physical rehabilitation and spasticity control

Patients with ischemic stroke who have undergone botulinum toxin therapy to relieve early spasticity are strongly advised to undergo active physical rehabilitation. The main goal of this stage is to improve the motor function of the affected limbs.

According to medical standards, comprehensive physical rehabilitation for CNS diseases should include:

• Individual physical therapy sessions.
• Occupational therapy aimed at restoring daily living skills.
• Traditional mechanotherapy.
• Robotic mechanotherapy.

As an adjunctive therapy for post-stroke spasticity, multifunctional muscle electrical stimulation or vibratory massage of spastic muscles is recommended. These methods achieve a temporary reduction in muscle hypertonia and contribute to further improvement of motor function.
