Podsumowanie	The SS-QoL is a disease-specific quality-of-life instrument designed to capture the multidimensional impact of stroke on survivors' functional and emotional well-being. Developed by Williams and colleagues in 1999, this 49-item scale addresses stroke-specific concerns including language, cognition, mobility, and emotional functioning. It is a gold-standard instrument for stroke outcome research and routine clinical monitoring of post-stroke recovery.	The Modified Rankin Scale is a simple 0-6 ordinal measure of global disability or dependency in patients with stroke and other neurological conditions. Originally developed by Rankin in 1957 and modified by van Swieten and colleagues in 1988, it remains the most widely used global disability outcome in stroke clinical trials and clinical practice. Its simplicity, brevity, and strong prognostic association make it the gold standard for acute stroke outcome measurement and is mandated as a primary endpoint in virtually all stroke therapeutic trials.
