The document discusses the use of mental practice in occupational therapy for stroke patients. It defines mental practice as the symbolic rehearsal of a physical activity through mental imagery without physical movement. The document reviews the types and effectiveness of mental imagery, and discusses several studies that show mental practice can improve affected limb function for stroke patients when combined with physical therapy. It concludes that mental practice is a promising rehabilitation approach but more research is still needed to establish guidelines and understand its long-term benefits.

2. Definition of mental practice Types of mental imagery The effectiveness of mental practice The use of mental practice in stroke rehabilitation and in occupational therapy Areas for further research Objectives

3. What is mental practice? ‘ the symbolic rehearsal of a physical activity in the absence of any gross muscular movements’ (Richardson, 1967) Mental practice is achieved through the use of mental imagery The effects of mental and physical practice are functionally similar

4. Types of mental imagery Visual eg Imagining the movement of a visual form Motor eg imagining your own hand moving Kinaesthetic eg imagining the feeling of your hand moving

5. Internal Imagery- an internal recreation of the task: Effective for planning a task External Imagery- an outside perspective of performance: More effective for learning & subsequent retention Types of mental imagery

6. The effectiveness of mental practice Combined with physical practice, mental practice: improves performance to the same, or a higher extent than physical practice alone increases the rate of skill acquisition may facilitate greater performance than that of a control condition of no input

7. Stroke rehabilitation approaches All approaches involve the process of re-learning Eg: Neurodevelopmental treatment (Bobath) Motor re-learning (Carr & Shepherd) Task- oriented approaches Compensatory

8. Mental practice theories It is debated whether mental practice relies on motor, cognitive or motivational processes Mental practice is more effective when learning simple tasks Imagery abilities may vary Tasks learned must be meaningful & prior experience of the activity is necessary

9. How mental imagery can promote functional independence through relearning

10. Mental practice used in occupational therapy Page, Levine & Leonard (2005) Investigated the efficacy of mental practice in increasing the function & use of the affected upper limb of 11 stroke patients. Randomized, controlled pre-post case series study Tasks were reaching & grasping a cup, turning pages & using a pen.

11. Mental practice used in occupational therapy Page, Levine & Leonard (2005) Results showed: Increased affected limb use and function Skills had been generalized to other ADLs after intervention

12. Mental practice used in occupational therapy Smania, et al. (1997) Studied the effectiveness of visuomotor imagery practice in rehabilitation of unilateral neglect Before / after trial on 2 participants Mental imagery included imagining patients at home, geographical areas, reverse spelling & mental representation.

13. Mental practice used in occupational therapy Smania, et al. (1997) Outcomes assessed using functional tests & neuropsychological tests Visuomotor imagery training found to improve performance deficits related to neglect

14. Mental practice used in occupational therapy Liu et al., (2004) Studied the efficacy of mental imagery at promoting relearning for people after a stroke Prospective, randomized controlled trial, of 46 stroke inpatients aged over 60 years. MP Protocol used picture cards, visualizing performance and watching videotaped performance

15. Mental practice used in occupational therapy Liu et al., (2004) Outcome measures used were the performance of 15 trained and 5 untrained daily living tasks Patients who engaged in mental practice improved their attention & sequencing ability Increased their relearning of familiar and new tasks

16. Benefits of using mental practice Increases affected limb use and function Can improve cognitive skills (eg attention, sequencing) Creates opportunities for clients to problem-solve Uses a client-centred approach Time / cost -effective

17. Areas for further research Establishing guidelines and protocols Motivational aspects of relearning through mental practice Long-term occupational benefits
