  1. Development of an Augmented Treadmill for the Rehabilitation of Children with Cerebral Palsy: Pilot Perspectives from Young Healthy Adult Users Mohammad Al-Amri,Daniel Abásolo, Salim Ghoussayni, & David Ewins Centre for Biomedical Engineering Gait Laboratory University of Surrey Queen Mary’s Hospital Guildford, Surrey, UK Roehampton, London, UK

  2. PRESENTATION OUTLINE

  3. CEREBRAL PALSY • Cerebral palsy (CP) is a group of disorders that: • Presents in the developing infant brain • Recognised as a non-progressive disorder • Different Clinical presentations : • Abnormal muscle tone (spasticity) • Abnormal coordination (ataxia) • Movement abnormality (athetosis) • CP is generally managed by a multidisciplinary approach: • Orthopaedic Surgery • Occupational therapy • Physiotherapy From FOOTSTEPS, Aaccessed in 04/06/12 From Children’s Treatment Network,. Aaccessed in 16/06/09

  4. REHABILITATION METHODS Limitations of Current Rehabilitation Methods: From LiteGait, http://www.litegait.com/, accessed in 16/06/09

  5. REHABILITATION METHODS Advantages of Treadmill Training: • Unloading of weak lower extremities allows individuals to safely practice gait • The number of steps can far exceed over-ground gait training (intensity) • Stationary positioning of the subject convenient for therapist assistance Limitations • Motivation • Speed Control

  8. AUGMENTED TREADMILL

  9. The WoodWay treadmill. A: two markers define the walking area on the treadmill, X0: zero point, Xref: reference point and B: pelvis clustur; clip with 3-point contact to calculate the origin of the pelvis origin segment.

  10. A: pelvis cluster – a sprung loaded frame with 3-point contact to calculate the origin of the pelvis segment; B: foot markers; C: motion capture camera

  11. PRELIMINARY EVALUATION

  12. PRELIMINARY STUDY • Completed a Questionnaire form • Get perspectives on : • Safety • Ease of using the RTSCA • Interaction between VR and RTSCA • Motivation

  13. RTSCA vs. CONVENTIONAL 10 participants found the walking on the treadmill when using the RTSCA was similar or better to using conventional speed buttons Sample of Questions Adapted Scale

  14. TREADMILL SPEEDS • Was there a significant difference between walking speeds on the treadmill when using the conventional treadmill speed buttons and the RTSCA? + 0.18 m/s when using the RTSCA A Wilcoxon test was conducted Significant
