Standard Treatment Approaches

1. Acute Stroke Management

For patients with a high NIHSS score, immediate treatment is critical. The standard approaches include:

• Thrombolysis: If the stroke is ischemic (caused by a blood clot), intravenous tissue plasminogen activator (tPA) may be administered within a specific time window (typically within 4.5 hours of symptom onset) to dissolve the clot[1].
• Endovascular Therapy: In cases of large vessel occlusion, mechanical thrombectomy may be performed to remove the clot, especially if the patient presents within 24 hours of symptom onset[2].

2. Post-Acute Care

Following the initial treatment, the focus shifts to rehabilitation and secondary prevention:

• Rehabilitation: A multidisciplinary approach involving physical therapy, occupational therapy, and speech therapy is essential to help the patient regain lost functions and improve quality of life[3].
• Medications: Antiplatelet agents (e.g., aspirin, clopidogrel) or anticoagulants may be prescribed to prevent future strokes, depending on the underlying cause of the stroke[4].

3. Management of Abnormal Movements

Given the ICD-10 code R29.717, addressing abnormal involuntary movements is crucial:

• Medications: Depending on the specific involuntary movements, medications such as anticholinergics, beta-blockers, or benzodiazepines may be used to manage symptoms[5].
• Botulinum Toxin Injections: For certain types of dystonia or abnormal movements, botulinum toxin injections can provide relief by temporarily paralyzing the affected muscles[6].

4. Long-term Monitoring and Support
