Member Benefits

iSTOP is a not-for-profit entity and therefore not in a position to plead for public funding. Non-profit organizations are associations, clubs, or societies that are not charities and are organized and operated exclusively for social welfare, civic improvement, pleasure, recreation, or any other purpose except profit.

iSTOP extends a warm thank you to all members for keeping your account up to date.

iSTOP is the International body overseeing the development of the IMS technique as developed by Dr. Gunn. iSTOP endeavors to encourage the acceptance and spread of this proven chronic pain treatment.

iSTOP’s objectives are as follows: 

  • To fund, facilitate, develop, implement, and promote activities, facilities, and programs, which will foster the education of physicians, physiotherapists, nurses, and other healthcare professionals with respect to the early diagnosis and appropriate treatment of soft tissue disorders such as tendonitis, bursitis, carpal tunnel syndrome, other sources of pain including nerve entrapment syndromes, disc and low back pain, and myofascial pain.  - see Treatable Conditions
  • To provide funding through scholarships, bursaries, loans, and other means to needy or deserving students who wish to study Gunn IMS. 
  • For the objects aforesaid, to employ scholars and scientists, and to acquire, maintain, and operate lands, buildings, libraries, laboratories, research equipment, and facilities.
  • To receive gifts, bequests, funds and property, and to hold, invest, develop, manage, administer, and distribute funds and property for the purposes of the Corporation, for such other organizations as are “qualified donees” under the provisions of the Income Tax Act, which are charitable at law and for such other purposes and activities as are authorized for the registered charities under the provisions of the Income Tax Act. 
  • To conduct any and all activities, and exercise any and all such powers as necessary for the achievement of the foregoing, and in furtherance of the objects of the Corporation.

iSTOP's short term and long term goals are contingent upon member support.


iSTOP has organized a membership drive for doctors, physiotherapists, and physical therapists who have completed a recognized GunnIMS course, and who employ it in their practice. Our minimum goal is to double our membership enrollment base in order to facilitate a future for Gunn IMS. Your paid membership fee contributes significantly towards iSTOP's long standing objectives. 

To reach our goal, please encourage ALL GUNN IMS trained practitioners in your clinic group to maintain an active membership with iSTOP. Although this may not make much sense from a business or budget point of view, it makes more than enough cents towards contributing to a celebratory community of pain practitioners who are SUCCEEDING and SUPERSEDING a world wide opioid crisis. We would like to see the directory and testimonial pages stuffed with success stories like yours!

Thousands of practitioners have been trained in Gunn IMS. Retrieving them all into a hub is like trying to gather feathers from a pillow tossed to the wind. Patient inquiries are regularly received at iSTOP seeking Gunn IMS certified practitioners worldwide.

Please help us find and restore practitioner members to the directory, for public good and sustainability. 

Community Board - Lost & Found

Submit Request

There are several avenues available for submitting your application for membership, subscription, etc     Application Form


Communications - Email System Check

iSTOP's email system receives international public inquiries in search of Gunn IMS information: potential patient direct inquiries, clinic referrals, CME courses, jobs, careers, etc.

Public inquiry emails are often sent direct to practitioner from within your publicly posted member profile.

To prevent iSTOP system generated emails from landing in your spam/junkmail, be sure to add   to your safe senders list, or add our email to your contacts.

Move Notices

Please remember to let us know when you have moved your practice to a new location, changed jobs, etc. We have noticed there is much fluidity in the physiotherapy group in regards to new and multiple clinic locations as well as personal contact information changes. Likely this is due to the boost in credentials and career advancement opportunity once GUNN is on your resume! 

Please keep in touch ; )

Certification Verification

Please remember to provide us with a copy of your certificate as issued through affiliate course provider, especially if you have recently upgraded your credentials.
