WOW!  It really is going to happen: an in-person exhibit hall!  We can’t wait to see you again and to provide the opportunity see TWO Kinarm Labs in action.  You have to  ‘try it to believe it’!

Ian, Paul and Anne are travelling to San Diego to answer your tough questions and give demonstrations of our Kinarm End-Point Lab and Kinarm Exoskeleton Lab.

Send Anne a note if you want to pre-book your visit to avoid a wait!

Exhibit hours: 9:30-5 pm, Sunday through Wednesday

Queen’s Cinq à Sept Research Talks: You can’t fix what you can’t see!

Posted on Apr 26, 2022

With thanks to Queen’s Faculty of Health Sciences for this post.

Video featuring Dr. Stephen Scott

Dr. Stephen Scott
Professor, Department of Biomedical and Molecular Sciences (cross appointed to the Department of Medicine) 
Incoming Vice Dean Research for Queen’s Health Sciences

Dr. Scott stars in the role of researcher – and inventor – in this exploration of the impact of his robot, Kinarm, which is changing the way we understand the brain. The groundbreaking robot allows researchers to perform clinical testing to assess a broad range of brain functions including motor skills, perception, memory, and decision making.

Trained in systems designs engineering, and with a background in physiology, Dr. Scott has combined two areas of expertise into something incredible. Kinarm is used to assess neurological impairments related to stroke, MS, ALS, Transient Ischemic Attacks, Parkinson’s disease, kidney dialysis, and more.

Dr. Scott holds the GSK Chair in Neuroscience and has won several awards for innovative research. He is widely respected in Canada as a forward thinker and a team researcher, with a huge number of collaborations across disciplines; you’ll see why through his Research Talk.

Technical Bulletin: Kinarm Gaze-Tracker; Impact of Reducing the Number Calibration Targets

Posted on Feb 8, 2022

Abstract:

The 13-point calibration routine for the Kinarm Gaze-Tracker is slow, and often difficult to achieve a good subject calibration with, often requiring multiple calibration attempts. Two factors contribute to these problems: the large number of target locations used in the calibration routine and the large size of the region over which the calibration is performed. This study quantified the effects on calibration accuracy when each of these factors was reduced. The results show that reducing the number of targets from 13 to 5 has a small impact on calibration accuracy (1.0±0.6° vs 1.1±0.7°) while significantly reducing the total time for the calibration routine. Further, reducing the size of the 5-point calibration region from 100% to 70% had only a marginal increase in uncertainty (1.2±0.9°). It is recommended that for most Kinarm users a 5-point calibration routine will save time without sacrificing the quality of the collected data.

Randomization Bug in Dex 3.8 & 3.9

Posted on Dec 7, 2021

Please be advised that if you are running a custom task program in 3.8.x or 3.9.x that there is a randomization bug in the Block Table if square brackets are used in the TP List (i.e. TP List in the Block Table = 10-15, [1, 2, 3]) and List Reps or Block Reps are > 1. Round brackets in the TP List are not affected by this issue. If List Reps and Block Reps are 1 then there is no problem.

Any TPs listed inside square brackets will always be randomized to the same order for a given block. The randomized order will be different each time the task is run.

While the bug will be fixed in an upcoming release, we wanted to provide immediate notice to all potential users as the bug is difficult to detect.

To workaround the bug, manually repeat the TP List as many times as required.

If you need to randomize TP List = 5, [1,2,3], List Reps = 2, Block Reps = 2 then instead use:

TP List = [5, [1,2,3]], [5, [1,2,3]], [5, [1,2,3]], [5, [1,2,3]], List Reps = 1, Block Reps = 1

Our thanks to the lab in Calgary who spotted the bug and reported it to us.
