Northernhay Clinic Computerised Gait Analysis
Gait analysis is the study of human locomotion, using the eye and the brain of observers, augmented by instrumentation for measuring body movements, body mechanics, and the activity of the muscles.
Gait Analysis uses
Gait analysis is used to assess, plan, and treat individuals with conditions affecting their ability to walk. It is also commonly used in sports to help athletes run more efficiently and to identify posture-related or movement-related problems in people with injuries.
The Gait Cycle
The Gait Cycle begins when the heel of one foot touches the ground and ends when the same foot, after having executed one step, is set down. The cycle begins with the Stance phase (the heel-to-toe contact sequence of the foot) and continues with a Swing phase, where the foot is suspended and proceeds in the air (on average the stance phase accounts for 60% and the swing phase for 40%).
Stance and Swing Phase
Each gait cycle consists of two phases, where both feet are in contact with the ground, called Double Support. The first Double Support (DS1 in Figure 1 refers to the right foot) is also called ‘Load Response’, whereas the second (DS2) is called ‘Pre Swing’). When only one foot is in contact with the ground, this is called Single Support.
Computer Gait Analysis
The Step is the distance between the tip (toe) of two subsequent feet or the distance between the heel of two subsequent feet (in the software you can choose how to calculate setting the parameter ‘Step length calculation’).
The Stride is the distance between the tip of two subsequent footprints of the same foot or the distance between the heel of two subsequent footprints of the same foot (always depending of the "Step lenght calculation" parameter).
Gait analysis is used to assess, plan, and treat individuals with conditions affecting their ability to walk. It is not necessary or indeed suitable for all patients and we will advise if this useful tool might be of use to you. We use gait analysis in conjuction with our specialised knowledge and experience of foot and limb types to treat or try to prevent injuries.
