  • Syringe micro vibrator (SMV) a new device being introduced in dentistry to alleviate pain and anxiety of intraoral injections, and a comparative study with a similar device
    Annals of Surgical Innovation and Research, 2011
    Co-Authors: Amir Hashem Shahidi Bonjar
    Abstract:

    BackgroundNeurologically, it is proven that stimulation of larger diameter fibers - e.g. using appropriate coldness, warmth, rubbing, pressure or vibration- can close the neural "Gate" so that the central perception of itch and pain is reduced. This fact is based upon "Gate-Control" Theory of Melzack and Wall.Presentation of the hypothesisSyringe Micro Vibrator is a new design being introduced for the first time in the field of Dentistry. This device is a promising breakthrough in pain and anxiety management and may deliver solution for clinicians plagued with patient pain phobia. It has an off-set rotating micro vibration creator with ultra high frequency and ultra low altitude that can be easily placed on any standard dental syringe and some disposable syringes. This device was registered as an invention in dentistry and received Iran National Patent number of 63765.Testing the hypothesisBy creating micro vibration, this device would be effective in reducing the pain and anxiety confronted with most types of intraoral injections as palatal, mandibular block, intraligamental and local infiltration. From the aspect of the patient pain management, this device contributes both physiologically (based on Gate Control Theory of pain) and psychologically (based on the device function as will be explained by dentist to the patient as a modern pain reducing technology). From the aspect of clinician, SMV motor provides vibrations with ultra high frequency to alleviate pain, but since it has ultra low vibration altitude, it has no adverse effect on the clinician dexterity and accuracy during injection and it does not interfere with pin point localization of injection site.Implications of the hypothesisUpon mounting on a conventional dental anesthesia injection syringe, SMV is switched on and the clinician then uses normal injection technique to administer the anesthetic. This device is not only a useful accessory device for ordinary patients, but also more useful for pediatric patients and those who have a phobia of intraoral injection or pain.

  • Peripheral nerve stimulation for chronic pain
    Current Pain and Headache Reports, 2008
    Co-Authors: Jaimie M. Henderson
    Abstract:

    Electrical stimulation has been used since ancient times to treat painful conditions. Electrotherapy for pain was largely consigned to the realm of quackery until the introduction of the Gate Control Theory by Melzack and Wall in 1965 provided a rationale for direct stimulation of peripheral nerves. Since that time, peripheral nerve stimulation has been applied to the treatment of painful conditions throughout the body, beginning with the major nerves of the extremities and culminating today in precise subcutaneous field stimulation targeted to specific areas of neuropathic pain. This article reviews the history, development, and current areas of interest in peripheral nerve stimulation for the treatment of neuropathic pain.

  • Utility of transcutaneous electrical nerve stimulation in neurologic pain disorders.
    Neurology, 2009
    Co-Authors: Andreas Binder, Ralf Baron
    Abstract:

    Transcutaneous electrical nerve stimulation (TENS) has now been used over 40 years in the treatment of pain. In 1967, Wall and Sweet successfully treated patients with “chronic cutaneous pain”; this proved to be the beginning for the increasing and widespread use of TENS in different nociceptive and neuropathic pain syndromes. The scientific basis for this treatment was presumed to be Wall and Melzack's Gate Control Theory,1 which stated that large nerve fiber activation, as applied by TENS, could modulate pain sensations conducted in small fiber nerves, by gating or blocking the transmission within central nociceptive pain pathways. Recent research and clinical observations in some patients, such as those with delayed analgesia or persisting anesthesia after stimulation, has made it clear that the Gate Control Theory cannot explain all effects of TENS; nevertheless, the lack of a solid scientific rationale has not hindered the implementation of TENS in pain therapy. In this issue of Neurology ®, Dubinsky and Miyasaki,2 representatives of the …

  • Using pressure to decrease the pain of intramuscular injections
    Journal of Pain and Symptom Management, 1996
    Co-Authors: Barbara J. Barnhill, Melinda D. Holbert, Nisha M. Jackson, Roberta S. Erickson
    Abstract:

    Abstract The purpose of this study was to determine if applying pressure to the site for 10 sec prior to an intramuscular injection would reduce injection pain, an approach suggested by anecdotal observation and the Gate Control Theory. The subject were 93 patients who had dorsogluteal intramuscular injections of immune globulin at a county health department. Forty-eight received the pressure treatment and 45 received a standard injection in which no pressure was applied. Mean pain intensity on a 100-mm visual analogue scale, adjusted for differences in injection volume, was 13.6 mm for the experimental group and 21.5 mm for the Control group (P = 0.03). The findings suggest that simple manual pressure applied to the site is a useful technique to decrease injection pain.
