2. Stroke statistics Prevalence is ~ 140 per 100,000
Incidence rates doubles for every 10 years after the age of 45.
Leading cause of disability.
2/3 patients survive
2/3 survivors have residual disabilities.
UK care costs 6% of Hospital expenditure
USA costs $ $25000 per patient.

3. Stroke therapy Hemiplegia is common
Early and intensive physiotherapy can improve outcome
Therapies must be customised for each patient
Therapy delivery could be improved

4. Therapy goals Increase sensory input
Stimulate re-learning in the brain
Recover muscle strength
Achieve functional goals that improve independence

13. Objectives of Gentle/s
1. Explore 'robot' mediated therapies for older persons.
2. Identify "best practice" therapies that can be 'robot' mediated
3. Estimate likely cost impact on health services
4. Develop a clinical prototype based on haptic interaction technology
5. Evaluate the clinical prototype
6. Quantify therapeutic impact
7. Brainstorm and research new technologies for stroke rehabilitation
8. Design and develop the technology to be safe and usable
9. Plan for effective exploitation of the technology

14. Workpackages WP 1 Management WP 2 User needs
WP 3 Rapid prototype clinical evaluator
WP 4 Ergonomic studies and prototype evaluation
WP 5 Phase 2 prototype physiotherapy robot
WP 6 Validation and commissioning of physiotherapy robot
WP 7 Exploitation measures

16. Why Haptic technologies
Designed for human interaction
Low cost 'games' machines
Medium cost VR interfaces
Designed to be 'passive' can be programmed to be active
Interest in distributed VR

18. Clinical study Based on haptic technologies
Randomised A:B (cross-over) design

19. Treatments Treatments should monitor and progress with patient
4/27/2019
tHRIL

20. Treatment examples Patient initiates movement and the robot completes
Direction of initiation of movement determines final goal (equilibrium point hypothesis)
Patient forced to coordinates reach and grasp
Robot only allows goal directed movements
Possibility for monitoring and evaluation
Perturbing movement overlayed to measure movement away from goal

21. Telerehabiltation Possibility of home or local clinic operation
Therapist and consultants specify and assess, rather than deliver treatments
High quantity data collection possible
Need to translate data into information

22. Slot machines Novel and entertaining motor function exercise!
R.R. Smedley - Slot machines: their use in rehabilitation after stroke
Novel and entertaining motor function exercise!
Significant improvement in range of motion, muscle strength, fine and gross motor coordination, and degree of depression
Metaphors to provide intellectual engagement in the physiotherapy
