Abstract
A system for measuring variation in the gait of a subject comprises a sensor arranged to measure variations in vertical position of the subject while the subject takes a series of steps, a processor, and a display. The processor is arranged to identify a plurality of points in a first one of the steps and a plurality of points in a second one of the steps, to identify a plurality of pairs of the points, each pair comprising one point in each of the steps, to determine a value of height for each of the points in each of the pairs, and to control the display to produce a display plotting the heights of the two points in each pair against each other.

- 19. A system for measuring variation in the gait of a subject while the subject takes a series of steps, the subject having a vertical position which undergoes variations during said series of steps, the system comprising a sensor arranged to measure the variations in vertical position of the subject, a processor, and a display, wherein the processor is arranged to identify a plurality of points in a first one of the steps and a plurality of points in a second one of the steps, to identify a plurality of pairs of the points, each pair comprising one point in each of said steps, to determine a value of said vertical position for each of the points in each of the pairs, and to control the display to produce a display plotting the vertical positions of the two points in each pair against each other.
- 27. A method of measuring variation in the gait of a subject while the subject takes a series of steps, the subject having a vertical position which undergoes variations during said series of steps, the method including measuring the variations in the vertical position of the subject, identifying a plurality of points in a first one of the steps and a plurality of points in a second one of the steps, identifying a plurality of pairs of the points, each pair comprising one point in each of the steps, determining a value of vertical position for each of the points in each of the pairs, and producing a display plotting the vertical positions of the two points in each pair against each other.
- 35. A system for measuring variation in the gait of a subject while the subject takes a series of steps, the subject having a vertical position which undergoes variations during said series of steps, the system comprising a memory arranged to store data recording variations in the vertical position of the subject while the subject takes the series of steps, a processor, and a display, wherein the processor is arranged to identify a plurality of points in a first one of the steps and a plurality of points in a second one of the steps, to identify a plurality of pairs of the points, each pair comprising one point in each of the steps, to determine a value of the vertical position for each of the points in each of the pairs, and to control the display to produce a display plotting the heights of the two points in each pair against each other.
