  • Another aspect of the present invention provides a self-contained electrical stimulation garment for muscle stimulation of a user of reduced motor ability, said garment having a sensor and an electronic muscle stimulator, said sensor detecting transient mechanical disturbances and causing said electronic muscle stimulator to effect muscle stimulation of the user through electrical connections associated therewith that are internal to said garment, said electrical connections being adapted to make electrical contact with electrodes on said user.
  • the garment has at least one accelerometer which detects such mechanical transients and activates the stimulator, and especially has three accelerometers arranged orthogonally.
  • the mechanical transients are of a magnitude that is above a predetermined level in order to effect activation of the stimulator.
  • the mechanical transients are applied by the user to any part of a limb of the user's body, said garment being attached to said limb.
  • the mechanical transients are applied by direct impact of the garment with an object.

  • Fig. 4 is a schematic representation of effects of application of the transient mechanical disturbance of Fig. 3;
  • Fig. 5 is a schematic representation of an alternate method of applying a transient mechanical disturbance
  • Fig. 6 is a schematic representation of another method of applying a transient mechanical disturbance.
  • Fig. 1 shows a garment in the form of a cuff, generally indicated by 1, having an electronic controller 2 located thereon.
  • Cuff 1 is shown as located on the forearm 3 adjacent the wrist 4 of a user.
  • Cuff 1 is made principally from the elastic material neoprene, preferably punched with small holes for breathability, although other materials could be used.
  • Electronic controller 2 may be in a variety of forms. For instance, electronic controller 2 could be in the form of a transmitter that emits infra red, radio or other types of signals to a remote device adapted to receive such signals.
  • the remote device would, in turn, respond to such signals by initiating or performing steps, functions or the like.
  • the electronic controller could be activated by transient mechanical disturbances, as described herein, and emit a signal to the remote device.
  • a signal could effect ON/OFF of the remote device e.g. a television set, or could initiate the next step in a pre-determined procedure, or initiate some other function in the remote device .
  • the transient mechanical disturbances could be detected within electronic controller 2 by a device activated by transient mechanical disturbances, especially an accelerometer.
  • the invention will be particularly described herein with reference to use of accelerometers .
  • the garment of the invention may be used to initiate functions as described above with respect to a remote device, the present invention will be particularly described with reference to use of the garment in embodiments in which electronic controller 2 is an electronic muscle stimulator, and with the garments being particularly intended for use by persons of reduced motor ability.
  • the electronic muscle stimulator has electrical connections associated therewith (not shown) that are internal to the cuff.
  • Another electrode receptacle system consists of three major components viz. a grid, a receptacle and an electrode. Two halves of the electrode receptable are snapped together across the grid to provide a fixed but moveable receptacle for the electrode.
  • the grid is fixed to the cuff, and positioned with respect to the user by means of, for example, a locator or shaped plate in the garment that conforms to the user e.g. a bony protrusion of the user.
  • a locator or shaped plate in the garment that conforms to the user e.g. a bony protrusion of the user.
  • FIG. 2 shows cuff 1 having electronic muscle stimulator 12 thereon in partially cut-away form.
  • Electronic muscle stimulator 12 has accelerometer 5 therein which, in the embodiment shown, is a cluster of three accelerometers arranged orthogonally. The accelerometers are arranged with orientations 6A, 6B and 6C that are at 90° to each other i.e. the orthogonal.
  • the cuff, arm, hand or other suitable location is subjected to a mechanical jarring, and the resultant transient mechanical disturbance is transmitted to electronic muscle stimulator 12 and detected by the accelerometers .
  • the signals from the accelerometers are summed, and a threshold-detection circuit with electronic muscle stimulator 12 is urged to determine whether the resultant summed signal exceeds a pre-determined threshold level. If so, the electronic muscle stimulator generates signals to effect movement of muscles e.g. using techniques described in the aforementioned PCT application of A. Prochazka et al .
  • the electronic muscle stimulator initiates a train of impulses to muscle under the electrodes, opening the hand.
  • a second transient mechanical disturbance exceeding the pre-determined threshold level causes the impulses to cease i.e. the stimulation is turned off.
  • the signals should be rectified e.g. the signals should have full wave rectification.
  • high pass filtering or other techniques may be used to improve the quality of the signal and/or accentuate differences between signals resulting from intentional jarring and from normal movements by the user.
  • Fig. 3 shows one example of mechanical jarring i.e. generation of a transient mechanical disturbance.
  • cuff 1 is located on the wrist of the right hand 6 of a user.
  • the index finger 8 of the left hand 7 of the user is shown as flicking electronic muscle stimulator 12.
  • Such flicking causes a transient mechanical disturbance which would be detected by the accelerometers 5.
  • electronic muscle stimulator 12 emits the signals required for opening of the user's hand, as shown in Fig. 4 where thumb 9 and forefinger 10 have moved apart .
  • the electronic stimulator used in the garment of the present invention would be intended to be activated by deliberate jarring or other transient mechanical disturbances, and not mere bumps or other mechanical transients that would occur during normal use i.e. wearing, of the garment.
  • the threshold detection limit may be appropriately set to discriminate between intended transient mechanical disturbances and transients occurring in normal use, and it is to be understood that provision of the threshold setting allows the stimulator to be so activated. This would reduce and preferably effectively eliminate accidental activation of the electronic stimulator.
  • a can 11 is illustrated in Fig. 5. Placing of can 11 in hand 6 would cause a second transient mechanical disturbance that would be detected by the accelerometers of the sensor associated with electronic muscle stimulator 12, causing a change in stimulation that results in the hand closing about the can.
  • Fig. 6 An alternative mechanical jarring is illustrated in Fig. 6, where can 11 is in hand 7 and is contacted with cuff 1.
  • a mechanical jarring could be effected on the arm, hand or wrist, or elsewhere where it could be transmitted to and detected by the accelerometer.
  • the transient mechanical disturbance could effect a passive response in the user e.g. by turning off the stimulus that effects the closing of a hand of the user, or the transient mechanical disturbance could effect a positive response e.g. by active stimulation of muscles that cause closing of the hand.
  • the present invention provides an alternative and simple method for activation of electronic muscle stimulation, to permit a user to perform a variety of functions, especially opening and closing of the hand to grip object.
  • the activation may be initiated by simple jarring, flicking or banging of the cuff, arm or hand, which may be particularly advantageous to persons of limited motor ability.
  • the present invention may find use in the treatment of or by persons with quadriplegia, paraplegia, hemiplegia, or hand or other tremors.
