| gait cycle | the time interval between two successive occurrences of one of the repetitive events of walking |
| support phase of gait. | 1. initial foot contact (0%) 2. loading response (0-10%) 3. midstance(10-30%) 4. terminal stance (30-50%) |
| swing phase of gate | 5. pre-swing (50-60%) 6. initial swing (60-70%) 7. midswing(70-85%) 8. terminal swing (85-100%) |
| major events of gait cycle | 1. initial foot contact (0%) 2. loading response (0-10%) 3. midstance(10-30%) 4. terminal stance (30-50%) 5. pre-swing (50-60%) 6. initial swing (60-70%) 7. midswing(70-85%) 8. terminal swing (85-100%) support phase swing phase |
| stride length | s the distance between two successive placements of the same foot |
| stride length is made up of | right and left step length |
| in normal gait right and left step lengths are...in patholigocial gait they are | -in normal gait right and left step lengths are the same -in pathological gait they may be different |
| toe out refers to the | degree of foot abduction |
| stride width | is the side-to-side distance between the line of the two feet |
| cadence refers to | he number of steps taken in a given time period |
| cadence is a measure of | half-cycles (i.e. steps) |
| cycle time or stride time is | cycle time (s) = 120/cadence (steps/minute) |
| walking speed (m/s) | distance covered in a period of time |
| relationship for walking speed | speed (m/s) = stride length (m)/cycle time (s) speed = stride length stride frequenc |
| each segment and each joint has | hree rotational degrees of freedom |
| hree rotational degrees of freedom | flexion/extension -abduction/adduction -axial rotation (i.e. internal/external rotation) |
| moment/torque | Moment = force * moment armperpendicular |
