Question:

What type of closed chain exercise would emphasize patellofemoral tracking in relation to the eccentric strengthening of the quadriceps and patellar tendon? a. Long arc leg extension b. Short arc leg extension c. Decline bodyweight squat d. Straight leg raise

Kerry W.
Answer:

c. Decline bodyweight squat. In this case, closed chain exercise incorporates weight bearing (as opposed to the other open chain options above). Weight-bearing alters the pull of the entire quadriceps mechanism during patellofemoral tracking range of motion accounting for strength and proprioceptive control at the core, hip, and ankle as well as the knee. Adding the decline to the squat changes the loading angle, allowing the quadriceps to eccentrically lengthen.

Which of the following statement about concussion diagnosis is incorrect? a. A concussion always presents with loss of consciousness b. Concussion symptoms can vary and are unique from patient to patient c. An athlete showing signs of possible concussion should be removed from activity immediately d. Concussion may occur as a result of a direct or indirect trauma to the body

Kerry W.
Answer:

a. A concussion always presents with loss of consciousness. This is false. On the contrary, according to the CDC most cases of concussion occur without any loss of consciousness. Any suspicion of head injury, with or without LOC, needs to be evaluated immediately and thoroughly.
