ABSTRACT

Background:

Evidence shows that gait training in older adults is effective in improving gait pattern but effects abate with cessation of training. During gait training therapists use a number of verbal and visual cues to place the heel first when stepping. This simple strategy changes posture from stooped to upright, lengthens the stride, stimulated pelvic and trunk rotation and facilitates arm swing. These principles guided the development of Heel2Toe sensor that provides real-time auditory feedback for each 'good' step, in which the heel strikes first.

Objective:

The objectives of this feasibility study are: (1) to contribute efficacy potential for home use of the Heel2Toe sensor; and (2) to estimate changes in gait parameters after five training sessions using the sensor.

Methods:

A pre-post study, with five training sessions over two weeks in the community were carried out, on a purposive sample of six seniors. Proportion of good steps, angular velocity at each step, and cadence, over a 2 minute period were assessed as was usability and experience.

Results:

All gait parameters; proportion of good steps, angular velocity, and duration of walking bouts improved. Coefficient of variation of angular velocity reduced, indicating consistency of stepping.

Conclusions:

Efficacy potential and feasibility of the Heel2Toe sensor were demonstrated.
