  3. Cerebral Palsy • Refers to a number of non-curable neurological disorders that appear in infancy or early childhood and permanently affect body movement and muscle coordination but don’t worsen over time. • Caused by abnormalities in parts of the brain that control muscle movements. • Effects the body’s movement, balance, and posture. • Many different treatments: Physical therapy, Botox to relax contracting muscles, drugs to control seizures, and orthotic devices.

  4. Spastic Cerebral Palsy • Most common type of Cerebral Palsy • Neuromuscular mobility impairment • Stemming from an upper motor neuron lesion in the brain • Have one or more tight muscle groups which limit movement • Patients have a hard time holding and letting go of objects • Difficulty moving from one position to another (stiff, jerky movements)

  5. The Client • Jack Davies • 12 years old • 72 pounds • 4’ 4” tall • Diagnosed with cerebral palsy, also suffers from scoliosis

  6. Project Purpose • Design a wheelchair capable of safely transporting Jack across sandy terrain • Important that there be enough restraints for Jack to be safe but also be comfortable • Device must be compatible with tumbleforms chair that parents have • Chair must also be able to support feeding tube and accompanying backpack apparatus • For maximum comfort, chair should recline at multiple angles

  7. Overview of Chair

  8. Division of Labor • Kyle O’Brien • Mechanical Design • Solidworks part simulations • Fabrication and Construction • Maya Alfonso • Parts Design • Dealer Contact • Fabrication and Construction

  9. Seat (Tumbleforms Chair) • Parents are providing a seat that is tailored to Jack’s size and support needs • Seat is best suited to provide support for Jack’s scoliosis • Removable to allow wheelchair to fold smaller • Allows family to replace cushions to adjust to Jack’s figure as he grows

  13. Reclining Mechanism • Tilt-in-space style reclining • Multiple angles to choose from

  14. Completed Work • Comprehensive and complete mechanical design • Parts and materials selection • Strength evaluation of selected metal parts

  15. The Client • Matthew Davies • 12 years old • Cerebral Palsy • 98 lbs. • 4’ 11” tall • Can walk, is receptive • Uses a walker or quad-canesto move around

  16. Purpose of The Project • Develop a posterior walker for Matthew that can be used across sand and other difficult terrain • Must be able to provide trunk support to promote proper gait • Safety is the most important aspect • Must be able to fold conveniently for easy transportation • Will have a broad height adjustment range to make it suitable for Matthew for many years
