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 Children’s Treatment Network,.

4. Limitations of Current Rehabilitation Methods : Staffing Number Space Allocation Number of Sessions Intensity of Rehabilitation Motivation and Confidence One approach to addressing some of these limitations could be the inclusion of treadmill training From LiteGait, http://www.litegait.com/, accessed in 16/06/09http://www.litegait.com/

5. 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 VIRTUAL REALITY

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. Overall Aim Evaluate the quality of the SVRS presentation Evaluate the quality of the SVR system presentation of 3D static images Evaluate the quality of the SVR system presentation of 3D scenarios Evaluate the overall performance of treadmill training Evaluate the performance of the RTSCA Examine walking speeds when using the RTSCA and conventional treadmill speed buttons

12. Participants: 13 young able-bodied ( 19-25 years old) Conventional: To determine their walking speeds prior the use of the RTSCA Maintained Normal, Slow, & Fast walking speeds for 20 seconds RTSCA Normal, Slow, & Fast without VR With VR

13. 10 participants found the walking on the treadmill when using the RTSCA was similar or better to using conventional speed buttons

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

16. Investigating its performance in a clinical environment by recruiting children with CP and clinicians Next Stage Implementing a low- cost markless system such as the Microsoft Kinect Sensor Future Work

17. Clinical team in the Gait Laboratory at Queen Mary’s Hospital for their feedback and support during the initial trials of tuning the RTSCA Participants from the University of Surrey for their time, enthusiasm and feedback
