From the standpoint of a physical therapist, I would recommend keeping neutral positioning as the primary concern with any unstable body parts. EDS can be hard to control if the person is not strong and supported in the joints, so PT consult for stabilizing exercises could be helpful. The ligaments and supportive structures are very loose with EDS compared to normal and it can be debilitating.
In addition I would consider utilizing larger grips on writing utensils, as it will tend to keep the fingers more in neutral. Also teach the to grip with minimal force to control the writing task. Strong grip will happen when under stress and any reminders or teaching on this will probably decrease the finger locking frequency.
I am not a fan especially of the straight pull-out keyboard trays. If your taller person is experiencing poor leg clearance, the tray is most likely too low for her to use anyway.
I also do not use keyboard trays much because they push the person further away from the desk work. Especially problematic if they need to write things down while doing computer work.
There are some keyboard tray options that are adjustable in height and that can be raised or lowered for the individual by unlocking a lever.
That said, I would only use keyboard trays where needed on an individual basis and only when appropriate.
I checked with the ergonomics department at OSU, but they do not do this type of research. Still looking for a contact at a university to do a study on this new fry basket handle design. Any ideas out there?
Joanette, I have several working prototypes that could be used. I need someplace that will try these in a vigorous setting and use alongside conventional and drop basket for employee feedback on comfort and preferences. A university doing the study as a 3rd party would be excellent. I may check at my alma mater, Oregon State to see if their HFE dept would want to take it on. Where are you located?
Your feedback is exactly what I’m hearing from any restaurant that does deep frying, whether fast food or sit down restaurant. See my prior reply to Gary that I just sent a few minutes ago. I believe I have the answer, but I have to find a company to license the manufacturing and sales to, in order to bring this to market. Any evidence or testimonials are helpful for me as evidence. Hoping to have this out soon. If you have testimonials or statistics about injuries from the existing basket design it would be very helpful to have.
I’m finding that there are no known or published ergnomic assessments of the fry basket use. I’m familiar with the drop bottom basket, but it still puts the wrist in ulnar deviation to lift and move the basket.
I have utility patents pending on a new change to the fry basket (and large fry pans, etc) that keeps the hand and wrist in neutral throughout the lifting and dumping task and greatly relieves stress on the wrist and hand. The lifting force is counterbalanced to transfer the load to biceps instead of forearm and wrist.
My problem in getting it to market is that a lot of potential sales companies have not seen articles on this problem. Evidence is scarce, but the problem is obvious to anyone who is experienced in ergonomic assessments. Any articles or even a 3rd party opinion would be helpful in my cause toward getting this to market.
