Definitions

  • the present invention relates to massage therapy devices, in particular to hand-held massage therapy devices.
  • Massage therapy can include whole body or localised vibration therapy.
  • a recipient During whole-body vibration therapy, a recipient would typically stand, sit, or lay on a machine supported by a vibrating platform.
  • a therapist typically places a hand-held vibrating device on certain parts of the body.
  • the direction and intensity of vibrations may determine how well vibration therapy works. Some machines produce only vertical vibrations, providing a percussive or Shiatsu-type therapy. There are many percussive and Shiatsu type massagers already. Percussive type massagers generally act normal to the surface of the tissue, depressing and releasing the surface. Other forms of vibrations therapy device produce vibrations that occur laterally.
  • Localised vibration therapy devices typically transmit a degree of vibration throughout the body of the device to the hand of a therapist holding the device.
  • a force is typically required to be applied by the therapist to the device in order to maximise therapeutic efficacy.
  • Continuous vibratory action against the hand of the therapist which is often combined with a requirement for continuous pressure to be applied to the device by the therapist, can cause an increased risk of injury to the therapist.
  • Such injuries can include Vibration White Finger, Repetitive Strain Injury (RSI) and Hand Arm Vibration Syndrome (HAVS) .
  • Examples of current such devices include the Niagara Therapy Cyclo-Therapy Handheld massager, another is the Rapid Release Therapy (RRT) Pro2.
  • RRT Rapid Release Therapy
  • Many current portable devices for delivering topical, medically effective vibration therapy have attempted to alleviate the effects of continuous vibration on the user. Such devices typically use an electric motor having eccentric weights, causing some or all of the body of the delivery device to vibrate. This is then held in the hand and applied to the body. Rotating weights are intended to provide a counterweight and/or flywheel effect to stabilise the body of the device during operation. Dynamic counterbalancing is the most common method for balancing rotational machinery. Examples of vibration therapy devices incorporating such technology can be found in, for example, WO 2016/123343 A1 , WO 2009/049185 A1 , and include the G5 GBM by General Physiotherapy Inc.
