Sports biomechanics

one complete propulsive cycle of a swimmer's arms, and the named style built around it.

In swimming a stroke is one complete propulsive cycle of the arms (and the named style built around it, such as front crawl), the unit by which a swimmer's technique and speed are analysed. Toussaint and Beek's Biomechanics of Competitive Front Crawl Swimming shows how velocity is the product of stroke length and stroke rate, and how propulsion and drag trade off within each cycle. The referent is a repeating body movement that generates thrust in water, unrelated to an engine's piston travel or a cerebrovascular event.[1]

Unit
One full limb cycle; velocity as stroke length times stroke rate
Recovery means
Not applicable
Measured by
Quantified by stroke length, stroke rate, stroke index, and propulsion-versus-drag analysis

Clinical neurology

Sudden brain injury from disrupted blood supply

In medicine a stroke, or cerebrovascular accident, is an acute episode of neurological dysfunction caused by infarction or haemorrhage of the brain, spinal cord, or retina: tissue dying when its blood supply is blocked or a vessel bursts. Sacco and colleagues' 2013 An Updated Definition of Stroke for the 21st Century, the AHA/ASA statement, anchors the definition to objective evidence of tissue injury rather than symptom duration alone. The referent is a clinical event in the central nervous system, sharing only the word with a piston's travel or a swimmer's arm cycle.[2]

Unit
An acute episode of CNS infarction or haemorrhage
Recovery means
Rehabilitation and reperfusion can restore function; outcome depends on the extent and location of tissue injury
Measured by
Established by clinical deficit plus imaging evidence of infarction or haemorrhage (CT/MRI)
