One team member had to work on his own while 2 others were out of town and one was unresponsive, so not as much work was accomplished as we were hoping would be by the time of the next meeting

Plans for the future?:

 

Week of 2/1-2/8- presentation week____________________________________________________

Meeting 2/2: Amanda and Nick (Will late)

• Spend today looking at materials
• Made a spreadsheet to keep track of materials and orders

Meeting 2/2 with Lowery: Nick, Amanda, Will

• Tell her she’s responsible for 23% of our grade (done)
• While at toys r us, look for other baby items
• Why didn’t we order buttons? We need to do that
• Look into other ways to do what we want. Like for tracks consider things not metal
• Divide the modifications we need into teams and have teams focus on a few different modifications at a time
• Take the tape measure with us to measure items at toys r us
• Can also go to Lowes and look at tracks like ones in drawers. We need to stop just looking at google. Go to home depot
• For buttons look at adafruit and digikey
• Plan to purchase materials rather than makerspace things. Like PVC pipe
• Don’t spend another $200 to make it RC capable, just tell them i’m sorry (done)
• Draw our circuit diagram so we can say in the final presentation: what did it look like, what changes did we make. Have a before and after
• Need to get a bucket together of materials we need from Lower’s cart (done)

Meeting 2/3 with kids and Teresa at Belmont: Taylor

• got to see Clayton and Luke again
• Teresa offered some valuable information on things almost all children with mobility impairments have
• Stressed that the posterior pelvic tilt causes them to slump forward and then their arms turn in and their head tilts to one side and their body also leans to one side ; this causes weakness in half their body and they begin to only look out of one eye and leads to monocular vision and then at some point their less dominant eye stops receiving information from their environment altogether
• She said to have their hips aligned and back of their hips against the seat back and have some kind of back support that forces them to sit up straight and bring their chest up allowing their arms to extend properly and then allow proper control of their hands

Meeting 2/3 with Nancy at High Hopes: Nick and Amanda

One girl: Lower body muscle weakness, like trouble going up the stairs she has to crawl. Goals are going up curb sized steps on her own

One girl: CP, had surgery to cut some spinal nerves

What have you found works best for the kids using the cars?

• The kids that are going in the car need the car to some significant postural support, chest strap, hip strap to hold the hips tight, height adaptable seat would be good because the kids get taller. Look at the 5 point convertible infant seat. 5 point would be good so we can adjust it and make it super tight.
• Maybe put a board for them to sit up straight but still lean back for the head. Definitely a board. Maybe velcro or clips to get it on the chair. Make sure the board isn’t too thick or find a way to do it so it doesn’t take away from the actual seat portion. Either a board or a new seat
• Don’t put an infant seat in it because the kids tend to lean back

What modifications do you guys have on your car?

• Pool noodles and kickboards and pvc pipe. Built a cage. That’s for postural support
• They built buttons with a doorbell from home depot and plexiglass for activation
• Big red button is good. Sound and light are good motivators. Maybe put it on the foot too, put velcro on back of button and and be able to stick it anywhere

Is there anything you see could be added or would like to see?

• Cross bar on the steering wheel is good
• Be able to cut any noise or light it makes. Disconnect the horn if there is one
• She likes the motor controller
• Middle and side foam for legs but velcro in and out

High hopes takes kids from 8 weeks to 7 years

Several kids have cerebral palsy

They use life age? Quality of life index

They also do 10 minute recording videos

• They’re going to send us the IRB for their go baby car they have, which will be good because they have all the data and organized code and it’s really cool. Will be good for qualitative analysis
• They’re doing a 16 week study

We had to tell her we can’t do the remote, sorry

Baby reflex: on stomach curl up, on back stretch out

• Yes to pressure sensor, no to head strap. Maybe try and make an option where the car is activated by standing. Could be cool
• Check out rifton and amtryke
• “creating a whole plethora of movement options for these kids is important. Anything to make them feel typical.” – Nancy Darr
• Send nancy an email reminder for: IRB, schedule of when they were planning on having OT residents there and when we should come and any patients she thinks we should definitely see

• Get more nuts and secure appropriate places
• Drill hole in sides of chair to make room for nuts
• Become familiar with High Hopes IRB before going on Friday. Put anything interesting in slides
• Put CAD pieces together

Meeting 2/24: Nick and Amanda

• Calculating the expected pressure our pieces can take (pressure = force/area (area that the pressure is being applied to)).
  • Area of the smallest spot the force is being applied (rectangle minus cylinder minus space between)
  • Area of smallest spot is (48.6 mm^2)
  • Strength is 7650 psi (pound per square inch)
  • Estimated max force: F=(46.8)(7650) = 2561.72 N. that’s assuming it’s solid at 100% fill
  • **One piece can support about 360 lbs on a vertical axis**
  • Find maximum weight for one piece. Find a piece that can hold at least twice what we think it needs to hold. May need to machine it out of aluminum. Be careful of the balance beam effect
• Do compression testing in lowery’s lab to find out if it can support that much
  • Machine is Autograph AGS-J by Shimadzu
  • Program is trapezium2
    • Set it to compress at 8 mm/min
  • Material is ABS
  • Machine will give us force and displacement so we calculate stress and strain from that
  • Snapped at 1.6 kN right down the middle of the hole along the grain
• Amanda and Nick go to High Hopes
• High hopes notes:

• Inclusion criteria: ages 9-60 months, known medical or developmental diagnosis that impacts his or her motor skills, cannot currently use another type of powered mobility, must demonstrate the ability to hold his/her head in supported sitting for 2 seconds, and to volitionally move his head and/or at least one extremity to access a switch to operate the ride-on toy
• More inclusion criteria/provider needs:
  • Provide direct supervision (within arm reach) to the child at all times when the child uses the adapted ride-on toy. The caregiver must be willing to supervise the child on a daily basis while he or she uses his or her ride on car and to complete the Adapted Ride-on Car use log. (See appendix
  • Provide basic maintenance to the adapted so that it remains usable on daily basis (i.e. keep it indoors away from temperature extremes and moisture when not in use, keep the car and camera batteries charged, immediately notify the investigators if they encounter any difficulties with the car or the child’s use of the car)
  • Provide verbal feedback to the investigators regarding any challenges with the car, child’s use of the car or the protocol
  • Caregiver must be able to read, write, and understand the English language, and investigators do not have access to translation services.
• Exclusion criteria: page 4
• Observational variables: quality of play, quantity of play, verbalizations, mobility activities
• BDI–> test includes 5 domains: cognitive, adaptive, motor, communication, personal/social development.
  • We’re hoping to tackle cognitive/gross motor/adaptive (spun from cause and effect, to help themselves)/social development
• Video recording using Nvivo 10 (qualitative analysis software) to track and inspect  head and eye movements, children’s motor, language and social behaviors, interactions with people and objects in the environment
• Kids are observed playing on the floor for 10 minutes and playing in the car for 10 minutes
• 8 children in the study, 3 of them go through an extended study with the car in their homes being observed every 2 weeks for 8 weeks.??
• Risks are on page 14
• Benefits are on page 16
• Page 25- observational data form. Scales are here. BFD
• Page 40-43 has interesting questions for the parents about child’s behavior
• ***Page 45 powered mobility skills list. The goals of the car***

Questions we have for them:

• What observation week/session are we in here?
  • 2 weeks ago was initial testing with 3 kids and fitted cars to them.
  • We are here for week 2/session 2
• The IRB says that observational testing sessions at weeks 3, 5, 7 will occur at the child’s home or at Belmont but there’s video being taken today. What is the difference between this and the session we’re in on now?
  • Modification is that they added “or at high hopes”
  • 3 5 and 7 doesn’t matter anymore. It’s just every other Friday around 2 pm for 16 total weeks. Then they redo all the big testing at the end of 16 weeks
• In the exclusion criteria, it’s stated that a child cannot have sufficient vision to clear obstacles while using the ride on toy. Why is that?
  • It’s a mistake. They SHOULD have sufficient vision to be in a car
• (pages 11,12,13) What’s the order of observations? How many kids go for 8 weeks? How many for 16? Explain “single session” kids, do they not participate in the study for longer than a day? How are the three extended study kids selected?
  • Everybody goes 16
  • Didn’t do the “first observation” session this year
  • Not even doing the single session kids, not happening
  • There wasn’t an original 8. they just picked the 3 kids based on convenience. Asking other therapists who they thought would cooperate and whose parents would cooperate
• Notes from her:
  • The IRB we have is old. It was a pilot. The new IRB added up to 10 kids and extended the study to 16 weeks and added the power mobility skills checklist
  • Marketing this as a toy, so FDA isn’t involved
  • Goal: want to set up a good pilot protocol. Hopefully be able to get funding so increase sample size. Seeing what things change with self-initiated power mobility

• Put design pics on website and google drive (seat mechanism, compression), make slide for compression testing

Meeting 2/25

• Amanda updated her slides, the website, log, and emailed Nancy to see when we can come back to High Hopes

Meeting 2/28: Nick and Amanda

• Get tracks scooted in 8 mm on one side
• Saw off top of center piece and place pvc
• Find a better way to unscrew the eye bolts. Think of a way it access it without needing to reach a hand in (like outside the seat)
• Amanda emailed Mary to set up a time to meet and discuss our progress report grades
• Amanda tried to get the tracks moved for the 3rd time but the machine shop is being difficult. Trying again later in the day
• Amanda discussed future meeting times with Nancy. Set for March 24 and 30
