Gait 1 Flashcards
The gait cycle can be broken into three functional tasks which are:
1) Weight acceptance
2) Single limb support
3) Limb advancement
Weight acceptance can be described as:
The period when weight is rapidly loaded onto the outstretched limb
Single limb support can be described as:
The period when the body progresses over a single limb
Limb advancement can be described as:
The period when the limb is moved from behind the body to in front of the body.
During gait the weight bearing limb accomplishes four functions:
1) Shock absorption minimising impact as limb meets supporting surface
2) Maintenance of dynamic postural stability (SLS)
3) Generation of propulsive force for forward progression
4) Conversion of energy by minimising vertical and horizontal displacements of the COM
Gait Cycle is defined as:
& is also known as:
The time from contact of one foot with the ground to the next contact with the same foot
Also known as a ‘stride’
A step is:
Contact between the ground and two different feet
Approximate step length (Male and female):
72cm
Approximate step length of males:
74 - 77cm
Approximate step length of females:
63 - 67 cm
Step WIDTH is approximately:
7 - 9cm…… Smaller than the width of pelvis
Name temporal characteristics of gait:
Cadence (step rate): 110 steps/min or 1.87 steps/sec
Step time
Stride time
Approximately how long does it take to complete one gait cycle?
1/2 second
What is approximate walking speed?
1.37 m/sec or 5km / hour……
Self selected walking speed for females is slightly slower than males:
