    Alber e motion wheels

    Hi all,
    My hands and neck are causing me problems so I need power assist wheels for my Kuschall chair, they are very expensive. Anyone any experiences of these they can share about how useful they are and what battery life is like. I have a power chair but prefer my manual lightweight for most things.
    Thanks

    I did an advanced search for "e-motions" on the Equipment thread; here is the result. Lots of feedback . . .

        I have the eMotion M-15s, and my batteries go for 2 or 3 days of 13 hours a day in the chair. It will take some tweaking of the settings, and it took me about 2 months before I was "one with the machine", but in about a week I was comfortable enough with them that it made getting around a hilly neighborhood and campus a *lot* easier and I started going out much more often. They take the effort out of wheeling on the grass or on carpet.

          Thanks Don, I was interested that you mention they helped with hills as my house is surrounded by hills to negotiate to get anywhere. I would be interested to know what "tweaks" you made, do the instructions that come with then help with this?

          I have a electric chair and the place I got it from made the "tork" on the battery/engine so that it coped with hills but, I lost a bit on battery life. !3 hours is a good battery life. I reaaky need to get some help with using my chair, my electric one is too heavy for me to take out in my car and use without help but I could manage the e motion wheels on my lightweight manual. If only they weren't so pricey!
          Thanks for your insight and info. Very helpful.

            There are two modes for the wheels, and I call them indoor and outdoor. You can control the amount of power that the push on the pushrim sends to the motors, you can also control how long the power goes to the motors, and how sensitive the pushrims are to your push. I have mine set so that I push fairly hard inside, and that the power sent to the wheels is relatively low ans it only sends the power for a second for each push. While wheeling inside, it feels much like pushing a manual, so that I get plenty of exercise. The only time I notice much of a difference is when on carpet, which feels like pushing on a hardwood floor.

            For outdoors, I set the amount of power going to the wheels at 90%, and the length of the power push to be 3 seconds, and the sensitivity low. This allows me to go up hills easily, and I don't have to push quite as often or as hard.

            I think that you may have to insist that your provider give you the Therapist/DME manual and the magnetic key that allows you to program the remote. This information is *NOT* in the user manual.

            Hope this helps.

              As of this fall, I will have been using emotion wheels (from the United States distributor Frank mobility) for 10 years. I first had the M12s (purchased in 2002) and then got the M15s (in 2010).

              The improvements have been excellent. Where I used to use 2-3 sets of batteries/day in the old system, the M15s battery life for me is 2 to 3 days. I try to plug them in every night, but often forget and have still never exceeded the battery life. One set of batteries is all I need.

              I have and recommend the ECS (Ergonomic Control System). I found a copy of the programming manual online and can send you a PDF if you need it. They are moderately easy to program. I have done it several times over the last two years and have really fine-tuned my settings.

              My level is C4/5 and I'm not super strong. I have a difficult time pushing regular wheels on much more than flat surfaces and smooth payment. However, with the emotion power assist I have not needed to get a power chair.

              I have pushed more than 8 miles before. I go through the grass and up-and-down hills quite a bit, and often with my labrador retriever service dog attached.

              I will tell you that I have had emotion wheels on three different chairs since '02, and the chair geometry makes a big difference. On the first chair (a very compact colours eclipse, which I already had), although I was able to add the emotion wheels easily to the chair, they were totally inappropriate for it. Because they create so much torque, the chair tended to tip back too much. Two chairs later, I finally have it figured out. I have very little center of gravity and a longer wheelbase on my new chair (2 weeks old), which is a very custom tilite ZR.

              Okay, I could go on and on. Let me know if you have specific questions. Also, feel free to shoot me a message if you wanted to Skype about it.

                p.s. they are not light--add 60 pounds to a chair
                wheels: 25 lbs. each; batteries: 5 lbs. each

                You would not want to be lifting them in/out of a car alone

                  Hi Don and wrongdog,
                  THANK YOU SO MUCH for the great tips and advice, this is what makes CC such an amazing source of help and comfort. I would never had got such helpful tips and info anywhere else. I now feel confident enough to go ahead and contact a dealer to see about purchasing the M15s which were the ones I had been looking at online, I will certainly look into the tweeks that can be made to the battery power system.

                  thanks again.

                    I have a question or two.. I have my emotion M-15's for one week now and I am still trying to customize the settings.

                    Donno what settings do you use inside? I keep crashing into my cabinets, doorways, sink etc. ? I think I mgiht want to try you "indoor manual wheelchair settings".

                    Wrongdog I am a C5-6 inomplete SCI, what settings do you use inside? The kitchen and doorways are hazardous for me. I have dented/gouged some walls and doors.

                    What settings do any of you use for going up and down you vehicle ramps/lifts?

                    Has anyone ever gotten stuck in grass, unven terrain?

                      who is paying for emotion wheels? Will Medicare look at them for any diagnosis?

                        @TM Happy to help. I hope you have a chance to use the wheels. I have really enjoyed them. I was an athlete before my injury and desperately tried to push regular wheels for the first few years I used the chair. I never got anywhere fast, and I started having shoulder and elbow trouble. 10 years later, and I have no major joint problems.
                        I probably put 15-20 miles on the wheels in the past week... good bike trails in Fort Collins.

                          There are several different settings you can adjust.

                          Sensitivity:
                          The amount of power required to move the wheel -- adjustable from 20% (little muscle power required to move the wheel) to 100% (much muscle power required to move the wheel). The default is 60%, and I use the default for this setting.

                          Then there are three settings that can be independently set for power stages 1 and 2: the "starting time," the "power assistance," and the "follow-up time."

                          Starting time:
                          The amount of time between pushing the rim reaching the peak motor output -- ranges from .3 - 1.2 seconds in power stage 1 (default .5) and from .5 - 1.5 seconds in power stage 2 (default .7). I use the default settings, but I have progressively decreased the amount of time on this setting as I have gotten more experience using the wheels, especially with power stage 2. Initially I had it set higher, because I was not very coordinated from left to right and found it more difficult to go in a straight line.

                          Power assistance:
                          The percentage of the maximum torque that is used for power stage 1 and 2. This can be set to a range of 30% - 70% in power stage 1 and from 60% - 100% in power stage 2. Like Don, I view the power stages as “indoor” and “outdoor” modes. I keep power stage 1 set lower (40%), so I do not bang into the walls and furniture. I use power stage 2 as outdoor mode, set to 100%.

                          Follow-up time:
                          How long the motor runs after the rim is pushed and released. Stage 1 can be set from .8 - 1.8 seconds (default 1 second) and stage 2 from 1.8 - 4 seconds (default 2 seconds). I keep stage 1 set to .8 seconds, again for indoor mode and not banging into walls, and I keep power stage 2 at the default 2 seconds. I would not recommend testing increasing this setting in an enclosed area. I would try it first in an open parking lot or similar.
                          A 4-second follow-up time is a lot of fun in a big open yard, because you coast after each push, but I cannot stay on the sidewalk with it set this high.

                          The way I use them:

                          I keep the ECS remote mounted on a small metal plate, attached with Velcro on the bar just to the front right of my seat cushion. When I am inside, I always use stage 1, and when I get to the bottom of my ramp at my house and outside, I reach down and push the button to activate stage 2. I use stage 2 outside almost exclusively (uphill, through grass, over rough terrain), but switch to stage 1 if I need to have more control––on a dangerous/narrow sidewalk and sometimes when I need to enter a building.

                          I use stage 2 when going up the ramp into my Van and into my house, but I remain very focused on controlling the push in a straight line.

                          As far as grass/terrain, I have had occasions where I have gotten stuck, and I try to stick with more smooth areas and avoid the bumps. I regularly walk my dog in my yard/parks, but pay close attention. The replacement value on my chair is ~$17,000, so I try to treat it with care.

                            In my experience, Medicare's participation in this process has varied. I would talk to different dealers to find out what they can do for you. For example, for my M12s, Medicare did not pay at all in 2002. I paid the full price out-of-pocket. In 2006, I got a second set of wheels after I had broken my first set (not sure how I cracked the hubs), and Medicare paid a significant amount, I believe 80% of the cost of the new wheels and one set of batteries. Then they paid a portion of the replacement cost of the batteries in 2007, but they refused it in 2009. I do not know what they will cover nowadays. I got the M15s in 2010 directly through Frank Mobility and the company covered the full cost.

                              Thank you for the thorough description. I have printed off your recommendations and will continue to tweak my settings. I am currently focusing on Power Stage I. I have previously used vertical projection rims for the last 33 years and I am pleasantly surprised that my weak fingers and wrists can handle a regular push rim with the help of the power assist wheels. I actually am braking too hard inside the house which is causing my chair to sway erractically. I can safely roll down my driveway, cross the street, push up the inclined bottom part of my neighbor's driveway and roll over to the community mailbox without killing myself using ower Stage 1.


                              I still haven't identified a place to mount the ECS control. I have desk armrests, brake extensions and swing away footrests. I keep thinking that I might need to find a tubular clamp to help me affix/mount some sort of docking device.


                              So you use Power Stage 2 going up ramps. Can I assume that you switch to Power Stage 1 going down ramps?


                              Thanks for all of your suggestions.
