Fall prevention training system and method using a dynamic perturbation platform
A new apparatus, system and method for fall prevention training is provided that delivers, studies and analyzes the biomechanics of a disturbance event, such as a slip or trip incident, so that an appropriate response can be executed by the person to reduce or eliminate the number of falls experienced. The apparatus includes a platform that delivers a disturbance event in less than about 500 ms and preferably in the range of about 100 ms to about 200 ms. The method includes a unique protocol for fall prevention training using the apparatus.
1. A disturbance simulation apparatus for fall prevention training of an individual, comprising:
a perturbation platform movable to create a disturbance event that induces a response from the individual as part of a continuous walking gait; the perturbation platform being a motorized belt and capable of moving to create said disturbance event having a duration of less than 500 ms; the belt enabling the individual to exhibit a continuous walking gait;
a plurality of sensors located proximate to the individual and the platform;
data being outputted from the plurality of sensors;
means for collecting and storing the data during a disturbance event; and
means for outputting the data.
2. The disturbance simulation apparatus of claim 1 , wherein the motion of the motorized belt is bi-directional.
3. The disturbance simulation apparatus of claim 1 , wherein the perturbation platform is two motorized bi-directional belts.
4. The disturbance simulation apparatus of claim 1 , further comprising:
an obstacle positioned proximate to the platform to induce the response from the individual to the disturbance event; the obstacle being a disturbance to the gait of the individual.
5. The disturbance simulation apparatus of claim 4 , wherein the obstacle is selected from the group consisting of a light beam, a three-dimensional object and a hologram.
6. A method of fall prevention training, comprising the steps of:
providing a motorized belt platform configured to support an individual standing thereon;
moving the platform, with the individual thereon, to cause the individual to achieve a continuous walking gait;
moving the platform to create a disturbance event having a duration of less than 500 ms that induces a step response from the individual as part of a continuous walking gait;
recording the step response of the individual;
locating a plurality of sensors proximate to the individual and the platform;
outputting data from the plurality of sensors;
collecting and storing the data during a disturbance event; and
outputting the data.
7. A disturbance simulation apparatus for fall prevention training of an individual, comprising:
a perturbation platform movable to create a disturbance event that induces a step response from the individual as part of a continuous walking gait; the perturbation platform capable of moving to create said disturbance event having a duration of less than 500 ms; the perturbation platform enabling the individual to exhibit a continuous walking gait.
8. The disturbance simulation apparatus of claim 7 , wherein the perturbation platform is a motorized bi-directional belt.
9. The disturbance simulation apparatus of claim 7 , wherein the perturbation platform is two motorized bi-directional belts.
10. The disturbance simulation apparatus of claim 7 , further comprising:
an obstacle positioned proximate to the platform to induce the response from the individual to the disturbance event; the obstacle being a disturbance to the gait of the individual.
11. The disturbance simulation apparatus of claim 10 , wherein the obstacle is selected from the group consisting of a light beam, a three-dimensional object and a hologram.
12. A method of fall prevention training, comprising the steps of:
providing a platform configured to support an individual standing thereon;
moving the platform, with the individual thereon, to cause the individual to achieve a continuous walking gait; and
moving the platform to create a disturbance event having a duration of less than 500 ms that induces a step response from the individual as part of a continuous walking gait.
