4. Hippotherapy Jacob Eisses Geunho Choi Anthony Reyes

5. What is Hippotherapy? Hippotherapy ▫A physical, occupational, or speech and language therapy treatment strategy that utilizes equine movement Why the Horse? 5http://www.americanhippotherapyassociation.org 5

6. Hippotherapy cont. The horse provides a dynamic base of support, making it an excellent tool for increasing trunk strength and control, balance, building overall postural strength and endurance, addressing weight bearing, and motor planning. 6

7. Who Can Benefit? Attention Deficit Disorder Autism Cerebral Palsy Closed Head Injury Developmental Delay Down Syndrome Emotional Disorders Hearing Impairment Multiple Sclerosis Muscular Dystrophy Paralysis Scoliosis Spinal Bifida Traumatic Brain Injury 7

8. Project Partner Needs Hippotherapy… ▫System that simulates horseback riding for children who have underdeveloped muscle allowing children to gain:  Strengthen core muscles  Posture  Motor function  Balance ▫Small children under ten  Debilitating illnesses and movement dysfunction  Poor posture  Limited mobility 8

9. Project Partner Info Need for Hippotherapy sessions on site Amazing results but costly -Average Hippotherapy ride cost ≒ $75~150 per session -Normally runs twice a week ≒ $7,200~14,400 per year Accessibility for urban families -barns are not near by big cities -saving travel distance (=cost) 9

10. Project Specification Overview Design Goal ▫Develop a working prototype  Start with simple design  Modify prototype to fore bar design if necessary ▫Design steering mechanism ▫Design roll cage like frame to provide safe seat belt to prevent from falling off ▫Make a handle for therapist to push ▫Childproofing 10

11. Two different designs 11 Design #1 uses misshapen wheels Design #2 uses normal wheels that drive 4-bar mechanisms to move saddle The following prototype is build from design #1

12. Prototype Specifications Overall dimensions: width 30” length 57.5” height 38” Chassis dimensions: 25” wide, 51” long Barrel is attached to chassis using 4 11” 2 by 4 legs 12

13. The barrel Semi circle ½ inch plywood Framed with strips of ½” plywood 2” wide 17” wide, 37” long, 10” tall 4 semi-circle ribs 2 by 4 base 13

14. Platform for wheel testing Goals Mimic horse steps Test different wheel designs 14

15. Front Wheel Shape 15 Tested 6 pedal flower and oval Flower shape worked better than oval Right wheel connected to left to maintain offset Each time wheel rolls onto pedal, mimics a step by the horse.

16. Rear Wheel Oval shape Provides up and down motion The change in radius causes change in height 16

17. Wheels will be made using ¾” plywood Used Plasti-dip to provide traction Difference between the radius of the major and minor axis will determine the change in height Flower will mimic 6 steps per rotation Oval wheel will mimic 2 steps per rotation 17 Determining wheel shape and size

18. 4 wheel vs. 3 wheel 18 4 wheels could not keep all wheels in contact 3 wheel design provides good movement and stability

19. 19 Journey of building the ride #1  Build design #1  Test full scale  If necessary, modify the prototype to utilize four bar mechanism

20. Wheel Design Front 20 Rear

21. 21 Determining Front Wheel Shape Considered 5,6 and 8 pedals. More pedals equals easier to rotate Used trig and geometry to determine the change in height as a function of edge length. For octagon change in height=.1*side length For hexagon change in height=.13*side length For pentagon change in height=.5*side length

22. 22 Determining Back Wheel Shape Diamond Shape with rounded edges Major radius 10” Minor radius 8” Change In height equals 2”

23. Fixing Axles on wheels 1.Cut out a groove for a pin 2.Drill through the axle 3.Put a pin through the drilled-hole 4.Glue the pin and wheel together 23

24. 24 Rear wheel slid instead of rotating Left to right movement broke the top layer of the plywood wheel allowing free rotation Movement provided from front wheels provided positive results Testing

25. Recap and possible failure report Plasti-Dip will NOT last long -failed after 2~3 feet run 25

26. 26 o Failure around the axle due to excessive torque -19 ft-lb @ stationary -equivalent to pneumatic pulse driver Recap and possible failure report

27. 27 Additions to Prototype Add a push bar Replace plasti-dip with bicycle inner tube rubber Replace back wheel with an oval Have metal plates welded onto axels so that wheels can be bolted onto axels

28. After completion of Prototype Aesthetics ▫Cloth/fabric to cover the frame and sharp edges Extra Safety ▫Childproof edge guards ▫Seat belt for saddle to secure patients better 28

51. Questions? 51

52. HEC Team Kaustuv Dasgupta Jinyuan Tian

53. St. Vincent Pediatric Rehabilitation Center In Indianapolis, Indiana Working with physical therapists ▫Patients are children ages 3-14 years old struggling with motor and visual skills 53 Our Project Partner

54. Develop a method of testing, recording, and quantifying a patient’s hand eye coordination skills Quantified data will be used by physical therapists to track patients’ improvement with therapies Needs to be completed with young patients in mind 54 Project Goal

55. HEC project began in Fall 2010 Games have been developed in past semesters The Rockband drum hardware was selected early on Fly Swat Game and Reaction have been completed Simon Game is under development 55 Project History

56. Timeline –Spring 2012 56

57. Hardware New piezo Attached with putty 57

58. Calculates the average response time for the child. Visual-Spatial Relation Fly Swat Games 58

59. Demo Fly Swat Game 59

60. Cymbals/No Cymbals ▫Spatial recognition 2-7 Sequences * Unlimited Runs 60 Testing and Scoring Score total run percentage Record response time * http://www.experiment-resources.com/short- term-memory.html http://www.experiment-resources.com/short- term-memory.html http://www.corporatecoachgroup.co.uk/blogDetail. asp?blogid=183

61. Visual Recognition Measuring Reaction Time Visual Discrimination Reaction Game 61

62. Demo Reaction Game 62

63. The game is always starting from a pre-defined drum(in this case, red). After the game is over, it automatically gets reset to the red drum, for a new run. These two modifications address the recommendations. Issues Addressed for the Reaction Game 63

64. The ability to store and retrieve previously experienced visual sensations and perceptions when the stimuli that originally evoked them are no longer present. 64 What is Visual Memory? http://www.achievepublications.com/chpt3.html http://www.teachingexpertise.com/articles/activities-to-develop-visual-memory-1104

65. Goal: To test child’s visual memory Similar to the Fly Swat game, utilizing the same kit and similar background layout. Simon’s Game 65

66. There would be four drum sets on the background, and drums will light up colors in a random sequence. A “glowy” drum color will show the user which drums to remember. User need to hit the drum in the same sequence based on memory. Results will turn out in terms of reaction time and hit correction percentage. The total number of drums to remember can be decided based on the number of runs selected. How Simon Game Works? 66

67. Flow Chart of Simon Game Initialize game Run Random Sequence Function Run Hitting Register Scoring Function End 67

68. Background will light up in a sequence Let me give you a demonstration The Simon Game 68

69. The current design of Simon game is not fully functional according to the direct user’s needs. For the future team, they need to develop a new criteria of calculating the percentage of correct hits. It is important to consider more about the sequence to be remembered and the number of hits, not just the latter. Issues 69

70. The scoring for the Simon’s Game needs to be programmed. For now, we are using the old scoring algorithm from the Reaction Game. Figure out a possible way to display the drum sequences at the top of the screen. Transition 70
