This gait pattern requires a high level of coordination and balance. [1] Another two-point gait pattern is the modified two-point pattern. [2] In this pattern there is only use of one crutch or cane on the side opposite to the injured leg, therefore there can not be any weight bearing restriction but is more used to provide extra balance. [2]
The gait analysis is modulated or modified by many factors, and changes in the normal gait pattern can be transient or permanent. The factors can be of various types: Extrinsic: such as terrain, footwear, clothing, cargo; Intrinsic: sex, weight, height, age, etc. Physical: such as weight, height, physique; Psychological: personality type, emotions
In a healthy individual walking at a normal walking speed, stance phase makes up approximately 60% of one gait cycle and swing makes up the remaining 40%. [3] The lower limbs are only in contact with the ground during the stance phase, which is typically subdivided into 5 events: heel contact, foot flat, mid-stance, heel off, and toe off.
Gait is the pattern of movement of the limbs of animals, including humans, during locomotion over a solid substrate. Most animals use a variety of gaits, selecting gait based on speed, terrain , the need to maneuver , and energetic efficiency.
Those who can tolerate partial weight bearing on both legs usually use the four point gait. The sequence is right crutch, left leg, left crutch, right leg. This is the slowest of all gaits but also the safest in that three of the four points are in contact with the ground at any given time. [9]
Gait deviations are nominally referred to as any variation of standard human gait, typically manifesting as a coping mechanism in response to an anatomical impairment. Lower-limb amputees are unable to maintain the characteristic walking patterns of an able-bodied individual due to the removal of some portion of the impaired leg.
Note, if there are less than 3 legs in stance then the animal is not statically stable. Form the support polygon by creating edges between these legs in a clock-wise manner. Determine if the center of mass lies inside or outside of the support polygon. The ray casting algorithm is a common approach of finding if a point is located within a ...
Currently, there are three different models available: Hocoma's Lokomat, the HealthSouth AutoAmbulator, and the Mechanized Gait Trainer II. [25] The Lokomat is a driven gait orthosis that consists of a computer -controlled exoskeleton that secured to the patient’s legs while being supported over a treadmill. [ 24 ]
