  1. Motor Control In Aging Amir ahmad bavand Mahdi fallahi Dr. Arshi Spring 2013

  2. Contents • Aging and it’s effects on motor control • Force production • Sensory function • Processing function • Rehabilitation of motor control disorders associated with aging • Bio-feedback • Hydrotherapy • Exercises, Sports and Games • Rehabilitation centers

  3. 1. Aging and it’s effects on motor control a. Force production

  4. Muscle and motor unit morphology • Reduction in muscle mass • Reduction in muscle fiber number • Changes in muscle fiber size • Motor unit number and size

  5. Muscle function • Strength • Fatigue • Dexterity

  6. Schema of changes in MUs

  7. 1. Aging and it’s effects on motor control b. Sensory function

  8. Sensory function • Estimating the position of body parts • Sway while standing • Shifting from vision to somatosensory • Aiming test for eye and hand • Velocity, duration, amplitude of initial movement • Corrective movement

  9. 1. Aging and it’s effects on motor control c. Processing function

  10. Processing function • Less effective balance strategy • Smaller and slower postural muscle response • Co-activation • Single-task walking gait speed <0.8 m/s: 24% • Dual-task walking gait speed <0.8 m/s: 62%

  11. 2. Rehabilitation of motor control disorders associated with aging a. bio-feedback

  12. Bio-feedback • A system which includes an EMG and a computer software. • The software gives information about muscle activity.

  13. Virtual environment design. The design of a virtual living room is illustrated. The virtual arm animates the patient's arm movement in real time. The patient can explore the virtual environment and perform the goal-directed reaching task. The green line indicates the ideal trajectory. The cone shape constrains the spatial error of endpoint position and provides direct knowledge of performance.

  14. Musical feedback design. Musical notes are distributed along the hand's path from initial location to the target. Reaching a particular distance triggers the corresponding note to play. The curve indicates the hand-to-target distance during the arm reaching and withdrawal

  15. 2. Rehabilitation of motor control disorders associated with aging b. Hydrotherapy

  16. Hydrotherapy • An exercise in which water eases the person’s movement.

  17. 2. Rehabilitation of motor control disorders associated with aging c. exercises, sports and games

  18. Exercises Heel to toe walk

  19. Step up

  20. Sports • Tai Chi • Better joint position sense • Improved muscle strength

  21. Games • Nintendo Wii Fit : • Improved balance and stability

  22. 2. Rehabilitation of motor control disorders associated with aging d. Rehabilitation centers

  23. Our Observations • a. Shoulder Wheel • b. Spring • c. Mirror • …

  24. Thank you 
