While moving both arms towards targets of identical size and distance, one arm had to mover over a hurdle, but the other did not. Movement time increased for both arms. Why?

While moving both arms towards targets of identical size and distance, one arm had to move over a hurdle, but the other did not. The movement trajectory increased for the arm moving over the hurdle, but so did the trajectory for the other arm. Why?

Limbs like to time movement together, either in-phase or out-of-phase. Why?

According the Sensory Organization test (SOT/ CTSIB) which of the following conditions isolates the vestibular system:

You are standing in soft sand with your feet together when your friend unexpectedly pushes you forward? To prevent a loss of balance you respond with the following muscle activation pattern (in order of recruitment):

Individuals with co-activation of the postural synergies most likely have a lesion in which area of the central nervous system:

You are standing in the dark on a pillow, in order to maintain postural stability your CNS is primarily relying on your:

You are walking through the forest when you unexpectedly trip on a tree root requiring you to employ a postural strategy to prevent you from falling down? This is an example of:

While walking with your patient, she encounters a freshly mopped floor? Prior to stepping onto the wet surface, she slows her walking and begins taking short, shuffling steps? Which of the following best describes your observations?

Which muscle group controls the knee from the end of the loading response to midstance (i.e. from 15 degrees of flexion to 0 degrees of flexion)?

Which of the following is the correct order of events for a normal reach and grasp?

Your patient's right arm is weaker than her left arm. During bimanual tasks you observe that the right arm is able to move faster (more like the left arm) than when the arm is moved individually? This is known as:

During examination of UE control, you observe your patient reach for an object. The patient exhibits slow movement and movement decomposition to reach the object. When asked to reach quickly, the patient over-shoots the object. Strength testing reveals good to normal UE strength. Sensation is intact. Where is this lesion?
