What is a gait cycle?
What is a gait disorder?
Cadence in sports involving running is a measure of speed calculated as the total number of full cycles (of both a right and left foot strike) taken within a given period of time, often expressed in steps per minute or cycles per minute. It is used as a measure of athletic performance.

Walking is an integral part of our daily locomotion and an important indicator of health. It is the most common type of physical activity for adults in their leisure time. "Human gait depends on a complex interplay of major parts of the nervous, musculoskeletal and cardiorespiratorysystems." 1. An individual's gait pattern is influenced by age, per...
Children take approximately 11 to 15 months to learn and develop gaitRefinement and normalisation of a gait pattern takes another 4 to 5 yearsChildren around the ages of 6 to 7 years will have a normalised, adult-like gait patternGait changes throughout the lifespanAn "ideal" gait needs to be both safe and energy efficient. For example: 1. The "ideal" gait of an individual with an orthopaedic injury and / or neurological condition may be considerably different from a clinician's picture of "ideal." 1.1. As long as the individual is ambulating as safely as possible and in the most efficient manner possible, th...
The five main functions of walking gait are: 1. To maintain support of the head, arms and trunk 2. To maintain upright posture and balance of the body 3. To control foot trajectory to achieve safe ground clearance and a gentle heel or toe landing 4. To generate mechanical energy to maintain the present forward velocity or to increase the forward ve...
Gait cycle
1. The gait cycle is the time from when the heel of one foot touches the ground to the time the same heel touches the ground again or a repetitive pattern involving steps and strides. The gait cycle is divided into two phases which are further divided into sub-phases: 1. Stance Phase (60% of the gait cycle) - during which some part of the foot is in contact with the ground: 1.1. Initial contact (heel strike) 1.2. Foot flat (loading response) 1.3. Mid-stance (single-leg stance) 1.4. Heel off (...
Centre of Mass
1. The point where the mass of the body is centred 2. Usually 5 cm anterior to S2 in adults 3. Also referred to as Centre of gravity 4. Centre of massis not a fixed point and changes in different positions such as sitting, standing and kneeling 5. Displacement of centre of mass 5.1. It is difficult to follow and evaluate the movement around S2. Another way to assess the displacement of the centre of mass of a body is to observe the head for a vertical representation of the movement of the COM...
Ground Reaction Force
1. Forces applied by the ground to the foot, when the foot is in contact with the ground 2. Generates external torque 2.1. External torque 2.1.1. Torque that acts upon the body 2.1.2. When external torque passes at a distance from the axis, there is rotation of the superimposed body segment around that joint axis 2.1.3. The magnitude increases as the distance increases between the ground reaction force and the joint axis 2.2. Internal torque 2.2.1. Muscle contractions to counterbalance extern...
Observe an individual's standing posture before assessing their gaitObserve an individual's footwear before formally assessing their gaitImportant measures of gait include walking speed, cadence (number of steps per minute), walking base width (measured from midpoint to midpoint of both heels), step length (measured from the point of foot contact to the point of contralateral foot contact) and stride length (linear distance covered by one gait cycle).
Unpredictable or highly variable gait cadence, stride length, or stride width indicates breakdown of motor control of gait due to a cerebellar or frontal lobe syndrome or use of multiple psychoactive medications.
Nov 28, 2023 · Definition. Gait is the action of walking (locomotion). It is a complex, whole-body movement, that requires the coordinated action of many joints and muscles of our musculoskeletal system. It mostly includes the movements of the lower limbs, upper limbs, pelvis and spine .
Understanding the gait cycle allows for effective gait analysis. When analysing gait, it should be done systematically, looking at each joint separately throughout the entire gait cycle and detecting deviations from normal.
Dec 5, 2016 · • Cadence: The number of steps taken per minute; also called step rate. The average cadence for a healthy adult is 110 steps per minute. • Walking velocity: The speed at which an individual walks. Normal walking velocity is about 3 miles per hour; walking velocity increases by increases in cadence or step length, or both.
