  • a mechanism for controlling a swing motion is complicated, as it has employed a plurality of linkages, for example, thus being subject to a higher risk of failure of the device.
  • the device of the prior art has been also associated with another drawback that it is unable to provide the training independently and exclusively directed to each of three organs, including a semicircular canal, a vision and a deep sensibility, each governing a personal sense of equilibrium.
  • An object of the present invention is, on the premise of its use in a standing posture for realizing the training in the leg segment, to provide a balance training device that allows a motion of a plate with a user carried thereon to be achieved in the form of a rotation in the lateral direction with respect to the body of the user while eliminating a need for any complicated linkage mechanism.

  • This arrangement allows for the plate 1 to make a swing motion around its revolving shaft when the user carried thereon take a motion and also to provide a tilting motion in an active manner by means of the motor 2 .
  • the motor 2 is adapted to be actuated and controlled externally.
  • the torque measuring mechanism may be one configuration employing the pair of force plates 41 as shown in FIG. 1 or may be the other configuration employing the commercially available rotation torque sensor 42 as shown in FIG. 2 , as already discussed above.
  • the torque measuring mechanism using the pair of force plates 41 comprises the pair of force plates 41 and an arithmetic processing unit (not shown).
  • the plate 1 includes the pair of force plates 41 each positioned on its top surface in the left and the right sides axi-symmetrically with respect to the revolving shaft.
  • Each of the force plates 41 comprises an integrated set of two sensors, including one for measuring a load applied to the plate 1 and the other for measuring a position of the center of loading when the user takes any motions as carried on the plate 1 .
  • the arithmetic processing unit may calculate the torque by multiplying a measurement of the pair of force plates 41 (load applied to the center of the loading) by a certain distance defined by an offset of the center of the loading from the center of axis of rotation of the revolving shaft (force X distance).
  • the configuration employing the commercially available rotation torque sensor allows for the rotating force (torque) applied to the plate from the motion of the user to be measured by means of a commercially available rotation torque sensor that has been attached to the revolving shaft of the motor 2 .
  • the rotation angle sensor 3 as shown in FIG. 1 is mounted to the clamp 7 , which has clamped the plate 1 at its front edge thereby to be attached thereto, and adapted to measure a rotation angle as the plate 1 is tilted.
  • FIG. 3 shows a block diagram illustrating a general configuration for controlling the motor by the torque measuring mechanism, the rotation angle sensor, the kinetic model analyzer and the motor controller.
  • respective components are connected to each other in such a manner that an output from each of the torque measuring mechanism and the rotation angle sensor 3 is input to the kinetic model analyzer 5 , an output from the kinetic model analyzer 5 is in turn input to the motor controller 6 , and an output from the motor controller 6 is then input to the motor 2 .
  • the kinetic model analyzer 5 determines a rotation angle of the plate 1 which may vary in dependence on the force applied to the plate 1 defined by the equation (1) as shown below, which is associate with FIG. 4 for easy understanding, thus providing the control of the motor 2 .
  • J ⁇ umlaut over ( ⁇ ) ⁇ +D ⁇ dot over ( ⁇ ) ⁇ +k ⁇ T m +T d (1)
  • the motor is controlled by using the force applied by the user and the rotation angle of the plate 1 as variable parameters under the condition of the rotation characteristics of the plate 1 defined by the spring constant, the viscous braking coefficient and the moment of inertia, which are all virtual as shown in FIG. 4 , and thereby the device can provide the training accordingly in dependence on the high or low level of performance in the capability of balancing of the user. Further, a certain magnitude of rotation may be applied to the plate 1 as the disturbance. That is, the device also allows for the training intended to respond to any external stimulation by applying the disturbance torque to the device.
  • the user steps onto the device with his/her feet in contact with the plate 1 and attempts to make a balance as much as possible so as not to lean laterally with respect to the body of the user.
  • the rotation angle of the plate 1 in the lateral direction with respect to the user's body is measured by the angle sensor 3 while the rotation torque of the plate 1 is measured by the rotation torque measuring mechanism, and the measured values are supplied to the kinetic model analyzer as shown in FIG. 3 .
  • the forces applied by the left and the right feet onto the plate 1 are measured by the pair of force plates 41 respectively and the rotation torque is calculated with the arithmetic processing unit by applying the measured force values to the equation (2) as shown below, which is associate with FIG. 4 for easy understanding, and thus calculated rotation torque value is supplied to the kinetic model analyzer as shown in FIG. 3 .
  • the rotation torque may be measured by the rotation torque sensor 42 and the measured value may be supplied to the kinetic model analyzer.
  • T m L ( F r ⁇ F l )cos ⁇ (2)
  • the kinetic model analyzer calculates an angle of equilibrium (an angle making the force applied by the user in balance with the rotating force of the motor) of the plate 1 , which may vary in dependence on the forces applied to the plate 1 , to provide the appropriate control so that the motor 2 is rotated to swing the plate 1 and thus to provide the balance training for the user. That is, the angle of equilibrium may be modified by increasing or decreasing the rotating force of the motor, and the user tries making a balance to achieve thus modified angle of equilibrium, thereby effecting the balance training to be provided.
  • the values of the viscous braking coefficient and the spring constant are those having been virtually introduced in the calculator (kinetic model analyzer) when determining the angle of equilibrium, and those values are known when the control is provided.
  • the disturbance torque value represents the amount to be given by the controller when the angle of equilibrium is determined, and it is a known value. Therefore, the measurement of the rotation angle and the rotation torque can provide the calculated value for the angle of equilibrium, as discussed above.
  • the training can be performed independently and exclusively on each one of three organs, including the semicircular canal, the vision and the deep sensibility, each governing a personal capability of balancing, by blocking the visual information, restricting the rotation of the head segment or locking the leg segment (ankle, knee joint) in the immobilized state during the training.
  • FIG. 5 shows graphical representations of the simulation results illustrating how the rotation torque and the rotation angle vary over time in conjunction with the change in viscous braking coefficient for the high or low level of performance in respective personal capability of balancing.
  • D015E80 and D015E95 represent the cases with the relatively small viscous braking coefficient, one plotting the variation for the relatively low level of performance in the personal capability of balancing, the other plotting the variation for the relatively high level of performance in the personal capability of balancing, while both of D100E80 and D100E95 represent the cases with the relatively great viscous braking coefficient, one plotting the variation for the relatively low level of performance in the personal capability of balancing, the other plotting the variation for the relatively high level of performance in the personal capability of balancing.
  • each of D015E80, D015E95, D100E80 and D100E95 simply designates the reference numeral for the data illustration.
  • the balance training specified in the semicircular canal is feasible by blocking the visual information and restricting the motions in the leg and body trunk segments during training.
  • the balance training specified in the vision is feasible by restricting the motions in the head, body trunk and leg segments and providing a video image of the external world in synchronism with the rotation angle of the plate during the training.
  • the balance training specified in the deep sensibility using muscle in the body trunk segment is feasible by blocking the visual information, restricting the head segment and restricting the motion in the leg segment during the training.
  • the balance training specified in the deep sensibility using joint and muscle in the leg segment is feasible by blocking the visual information, restricting the head segment and restricting the motion in the body trunk segment during the training.
  • the blocking of the visual information may be achieved by covering eyes with a blinder, for example.
  • the restricting of the head/body trunk segment may be achieved by placing the armpits on the bars, such as hand-rails, with the body leaning against the bars.
  • the fixedly locking of the leg segment may be achieved with a certain type of assist tool inhibiting the bending motion in the ankle and/or the knee joint, which is mounted in the leg segment so as to prevent the movement and/or rotation thereof relative to the plate 1 . It may be also feasible by the user taking the sitting posture.
  • the balance training device owing to its configuration as described above, can achieve the rotation of the plate with a user carried thereon in the lateral direction with respect to the body of the user while eliminating the need for any complicated linkage mechanism. Further, the balance training device of the present invention is suitably applicable as a training device allowing for the training independently and exclusively directed to each one of the three organs, including the semicircular canal, the vision and the deep sensibility, each governing a personal capability of balancing.
