Stroke and functional rehabilitation: the Chinese experience

Area of Science:

• Neurology
• Pharmacology
• Rehabilitation Medicine

Background:

• Cerebrovascular disease presents high prevalence, incidence, and mortality rates in China.
• Functional rehabilitation post-stroke is a critical medical and social need.
• Almitrine-raubasine is utilized in China to enhance stroke recovery.

Purpose of the Study:

• To document the clinical efficacy of almitrine-raubasine in the convalescent period of cerebrovascular disease patients.
• To evaluate if almitrine-raubasine accelerates functional rehabilitation compared to placebo.

Main Methods:

• A double-blind, placebo-controlled study involving 100 patients with ischemic cerebrovascular disease.
• Treatment with almitrine-raubasine or placebo for 3-6 months, with a 2-week drug washout period.
• Monthly clinical examinations, neurological deficit scores, Barthel index, Hasagawa Dementia scales, and CT scans.

Main Results:

• Almitrine-raubasine enhances arterial oxygen content, promoting cerebral aerobic metabolism during ischemia.
• Positron emission tomography indicates normalization of the ischemic penumbra area in the acute phase.
• Single photon emission computed tomography shows restoration of normal cerebral vasodilator response in the long term.

Conclusions:

• Almitrine-raubasine demonstrates potential in improving cerebral oxygenation and metabolism post-stroke.
• The drug may accelerate functional rehabilitation in patients recovering from cerebrovascular disease.
• Further clinical studies are planned to confirm the therapeutic benefits of almitrine-raubasine.
