Understanding Gait: Anatomy, Physiology, and Abnormalities
This guide explores the fundamentals of gait, defining normal and abnormal walking patterns. It examines anatomical aspects, including the roles of the nervous system, muscular system, joints, and bones. Delving into common causes of gait abnormalities, the text discusses various gait types like circumduction, scissoring, and waddling, highlighting their anatomical correlations. It provides insights into conditions affecting gait, such as stroke, trauma, and muscular disorders. This comprehensive overview is essential for understanding the biomechanics of walking and diagnosing gait-related issues.

Presentation Transcript
objective • Definition of the gait • Anatomical aspect of normal gait • To understand basic physiology of the gait • To understand the normal gait • Abnormal gait in relation of anatomical abnormalities • Study of each joint, bone muscle and nerve involved in the gait. • Review some common causes of gait abnormalities.
definition • The maintenance of an upright posture and act of walking
Anatomical aspects of the gait • For normal gait we need normal: • Nervous system : CNS • PNS • MusculSkeletal system: muscle • joint • bone
Nervous system • cortex: cerebellum • basal ganglia • Brain stem • Spinal cord • peripheral nerves • NMJ • muscle
Abnormal gait in relation of anatomical abnormalities • Cortex: circumduction gait, Apraxic gait • Spinal cord: scissoring gait • Peripheral nerves: motor fiber foot drop,high step gait • sensory fiber:sensory ataxia • NMJ: waddling gait • Muscle: waddling gait • Basal ganglia: short step gait, Shuffling gait • Cerebellum: cerebellar ataxia,Tandem gait • Joint and bone: Limping gait
Review some common causes of gait abnormalities • Cortex: stroke • Spinal cord :trauma, compression • PN: DM,drugs • NMJ: mysthenia gravis • Muscle: polymyocities • Joint: arthritis • Bone :fracture
