We’ve Got DOI-s!

At long last we’re official, and the GCMAS 2021 conference proceedings have DOIs attached. You can find the official proceedings here or else use the DOI:

If you’re not familiar with these, digital object identifiers (DOIs) are intended to provide a “permanent” link to a resource such as an article, abstract, or even work of art. What this means is that organizations that get their own DOI prefix (ours is 10.52141) commit to taking the responsibility for maintaining resource links in perpetuity. Right now, these resources live on

What does this mean for you? It means that now you will finally be able to start citing GCMAS abstracts in publications via their DOI. DOIs make documents easier to find as they are stable regardless of the location of the resource. In academia, many of us are asked to provide DOIs of our work to “prove” that the work was published. This can be big if you are going for promotion.

When CrossRef accepts an organization as a member, they also ask that that organization use DOIs in all modern publications to help researchers more easily find cited works. Legacy works such as older conference proceedings can be grandfathered out of this requirement. What this meant for us is that for all abstracts submitted this year which did not list DOIs in their references, these DOIs or some type of URL had to be found before the conference proceedings could be listed officially. In some cases finding these were trivial, but in others where the references were by first author, year, and journal, sometimes this was labor intensive. In any event, that’s now done for 2021. I’m now going to try to do the same for the 2020 unconference as I have time. With luck those proceedings will have DOIs in the not too distant future.

One more thing – both the proceedings as a whole AND each individual abstract has a unique DOI. You should go to to find your paper and note the assigned DOI in the event you want to include them in your CVs and other documents.

All the best!

Watching Videos Post-Conference

So GCMAS2021 is over at last, but you’re back because you need to find a session video. The first step is to login. Remember that WordPress is fairly aggressive with enforcing password changes, so if you haven’t logged in for a while, you may be asked to change your password. Also, if you need a password reset, it seems that institutions that use SafeLinks may have problems getting reset emails. Email me if you have any issues, and we’ll get you in.

The screencast below shows you where to find everything and explains some of the site design changes post-conference. In short, you will go to the new “Recordings” tab and look for video icons at the top of the session information to the right. Clicking on that icon will take you to the recording of the video for that podium session.

What if the video isn’t there yet?

Videos take a bit of time for online systems to optimize for playing even after editing done before uploading, so if everything is not up and available immediately, please understand that it takes time.

In any event, thank you all for a great conference, and I hope to see you somewhere in person BEFORE next year.

All the best,

Tim Niiler

Poster Sessions and Zoom Room 2

There have been a lot of questions about Zoom Room 2 and how the posters sessions will run. This video will (hopefully) answer these questions and get you oriented

Note that posters (pdfs) and 3 minute video presentations of those posters are available for you to review right now from our “Program” or “Meeting Room” tabs. However you must be logged in to to view these. [Note this is not the same login as for OpenConf or – there is no single sign on.]

During the 1st 30 minutes of the official poster sessions (Tuesday June 8 10:05am-11:35am and Wednesday June 9th 3:40pm-5:10pm) poster authors assigned to those sessions have been asked to be available to discuss their work with you in breakout rooms in Zoom Room #2 (found in “Meeting Rooms” Tab).  They can stay later, of course, but if you’d like to interact “live” that’s the time to do it. If you have other asynchronous questions, please use the forums either by starting at the “Forum” tab, or go to the Meeting Rooms and click on the poster session. Then click on the golden forum icon (shown below)

at the head of the list of posters and you will be taken directly to the forum of interest. Don’t forget to list the poster number in question to ensure that the authors see your post and click “Subscribe” to the forum if you’d like an email alert about a response.

Poster presenters should show up at Zoom Room 2 on the day and time (remember Eastern Daylight Time is UTC – 4.00 hours) of the start of the session and let our Zoom technician, Samantha know which room you should be in.

Note that you can also come here anytime during the conference to visit Vendor/Exhibitors and to just meet with colleagues for a quiet chat. Just come to the room, and ask Sam to assign you to a free breakout room.

Let us know if you have any additional questions about posters!

All the best,

Chris Church (Program Chair)

Authors Q&A: What do I upload, and When Can Others see it?

There have been a number of questions of late regarding the presentation format for the conference. In this post, I hope to clarify things. See below for details!

If you’re a podium presenter

You are presenting live at the time on the schedule. Podium presenters need only submit their Power Point by May 22.  We are having presenters do this so as to avoid staging problems with presentations.  Our tech people will be running the presentations, and podium presenters will be narrating and having slides advance by stating “next slide.”     We will record their presentations via Zoom. Uploads for podium authors can be made here if you are logged in.

If you’re a poster presenter

Poster presenters are asked to be available in the scheduled Zoom room for Q&As about their posters. When poster sessions are on, we will have breakout rooms (per poster) for poster presenters to field questions. These will NOT be recorded. We ask that poster presenters post PDFs of their Power Points and a short 3 minute video introduction of their posters by May 22 so that they will be accessible in late May to all registered conference attendees. Uploads for poster authors can be made here if you are logged in.


Abstract authors who login only have access to the type of upload that fits them. If you are a poster author, they can upload MP4 and PDF files. If you are a podium author you can only upload PPTX files. If you are both, you have access to both types of uploads. We figured it was easier for people to have one login and multiple roles than separate logins for each abstract they submitted.

Access to uploaded and recorded materials

All AV materials will be stored on the website for the duration of our contract (Feb 2022) with SiteGround. After that, they will be put on for future consumption as decided by the board. AV materials will be available as follows:

  • Abstracts submitted via OpenConf: By Late May 2021 – Feb 2022.
  • Poster pre-recorded videos (MP4): Late May 2021 – Feb 2022.
  • Poster PDFs: Late May 2021 – Feb 2022.
  • Podium PPTXs: Only available to tech staff and presented live at scheduled times.
  • Recorded video of podium sessions (for example “Spine and Upper Extremity”): Available the day after the presentation – Feb 2022.

Availability of materials to paid conference goers is based on full or single day registration. For CME/CEU credit, materials must be watched within 1 month of the conference as per AMEDCO guidelines.

I hope this helps to clear up some things. As always feel free to contact me if you need more information or help. Watch this space for further updates as the website is about to start growing very quickly.

CMLA Luncheon Agenda Announced

When: Tuesday, June 8th at 12.30 (EDT) via Zoom

Gordon Alderink, PT, PhD
Jean L. Stout, PT, MS

The CMLA is the Commission for Motion Laboratory Accreditation.

Each year at the GCMAS meeting we provide an update on the accreditation process and a workshop for those interested in submitting an application for accreditation. Anyone who is interested in this topic is welcome to attend, but for those who intend to submit an application in
the near future it is strongly encouraged. During this session, we will provide an overview of the accreditation processes, and additional information of interest to GCMAS members who might seek accreditation for their institution.

Following a brief introduction, this year’s workshop format will consist primarily of a Q & A session with available members of the CMLA Board of Directors to answer general and specific questions regarding applications.

Update: You can find a PDF of the presentation here.

There is no charge for the workshop, but preregistration for the session is required.

For more information on CMLA and the accreditation process, please visit the CMLA website at

GCMAS is accepted as a DOI provider

This week, the GCMAS was accepted by CrossRef as a DOI provider. DOIs – Digital Object Identifiers – are valuable to researchers and clinicians alike in that they enable one’s work to b e indexed and more easily found across the web. DOIs are intended to be permanent links to academic work be it abstracts, conference papers, journal articles, webinars, or regular papers.

CrossRef is a not-for-profit membership organization that exists to make scholarly communications better.

Our intent at GCMAS is to use DOIs to index our conference papers so that researchers can see what has come before, benefit from this research, and avoid reinventing the wheel. Attaching DOIs to our research also makes this work more publicly accessible and helps our members to more widely disseminate our work.

We’ll announce soon when our DOI server is up and running.
