Stride
Stride
Stride (/straɪd/), from the Old English stridan meaning "to stride", is a term used in the medical field to describe the manner or style of walking. It is an important aspect of human locomotion and is often evaluated in various medical examinations and diagnoses.
Definition
In medical terms, stride refers to the cycle of one complete step during walking or running, starting from when one foot first contacts the ground to when the same foot contacts the ground again. It is a crucial component of gait analysis, a method used by healthcare professionals to assess the way an individual walks or runs.
Components of Stride
A stride consists of two phases: the stance phase and the swing phase. The stance phase is the part of the stride where the foot is in contact with the ground, while the swing phase is the part where the foot is in the air, moving forward.
Related Terms
- Gait: The pattern of movement of the limbs of animals, including humans, during locomotion.
- Stance phase: The part of the walking cycle where the foot is in contact with the ground.
- Swing phase: The part of the walking cycle where the foot is in the air, moving forward.
- Gait analysis: The systematic study of animal locomotion, more specifically the study of human motion, using the eye and the brain of observers, augmented by instrumentation for measuring body movements, body mechanics, and the activity of the muscles.
Clinical Significance
Abnormalities in stride can indicate a variety of medical conditions, including neurological disorders, orthopedic conditions, and injuries. For example, a shorter stride length can be a sign of conditions such as Parkinson's disease or arthritis. Therefore, understanding and analyzing stride is crucial in the diagnosis and treatment of these conditions.
