BME430. Please describe the proprioceptive feedback control of human movements.
BME430.
Please describe the proprioceptive feedback control of human movements.
After doing so please elaborate on the following points:
a. What are the components of the system? What are their transfer function?
b. make a block diagram that describes the feedback loop
c. Describe the interaction between Golgi-tendon-organs and the stiffness of the muscle
d. Using the diagram in the previous question describe what happen when the person tries to lift a carton of milk thinking it is full while the cartoon is empty. Which block is affected by this error? Please elaborate
2. Describe how the increase in stretch reflex gain can cause the instability of the control loop in stroke survivors. After doing so please elaborate on the following points:
a. Identify the block that will be affected
b. Formulate the equation to show that the solution is unstable describing the root locus of the system.
3. Describe an experimental protocol to identify the stiffness of the arm during a point to point reaching movement.
After doing so please elaborate on the following points
a. What is the impact that this knowledge will provide in helping individuals with Parkinson's diseases
b. Please describe in detail the process of regression. How can you make sure that you can separate stiffness from damping and inertia/mass? Please elaborate the details with a numerical example and a short Matlab program
