সারসংক্ষেপ	Focal Animal Sampling (FAS) is a systematic observational method in which an observer focuses on one individual animal at a time, recording its behavior continuously or at regular intervals for a fixed period. Introduced by Jeanne Altmann in 1974, FAS provides detailed, quantitative ethograms of individual behavior, making it essential for studying animal behavioral ecology, welfare, and responses to environmental changes.	Equine Gait Analysis is a systematic evaluation of a horse's movement patterns at walk, trot, and canter to detect lameness, asymmetry, and biomechanical dysfunction. Combining visual observation with increasingly sophisticated instrumental techniques (force plate analysis, kinematics, accelerometry), gait analysis is essential for diagnosing the causes of lameness, monitoring recovery from injury, and evaluating the safety and suitability of sport horses.	Polysomnography (PSG) is a comprehensive multi-channel physiological recording method that simultaneously records brain electrical activity, eye movements, muscle tone, respiratory effort, oxygen saturation, heart rate, and limb movements during sleep. First systematized by Rechtschaffen and Kales in 1968, polysomnography is the gold standard for diagnosing sleep disorders, characterizing sleep architecture, and assessing the quality and organization of sleep in humans and increasingly in veterinary species.
