FRC FRC Neurological Adaptations and Motor Control 1 — Questions and Answers
Question 1: In FRC, what is the primary neurological goal of Controlled Articular Rotations (CARs)?
- To increase muscle hypertrophy
- To maintain and map joint range of motion in the nervous system (Correct answer)
- To reduce joint inflammation
- To improve cardiovascular endurance
Correct answer: To maintain and map joint range of motion in the nervous system
CARs are performed to maintain the neural maps of joint range of motion by actively moving joints through their full available range.
Question 2: What does the term 'articular neurology' refer to in the context of FRC?
- The surgical repair of joint nerves
- The study of how the nervous system perceives and controls joint position and movement (Correct answer)
- A pharmacological approach to joint pain
- The measurement of nerve conduction velocity
Correct answer: The study of how the nervous system perceives and controls joint position and movement
Articular neurology in FRC refers to how the nervous system senses, maps, and controls joint positions and movements to ensure safe and efficient motion.
Question 3: Which concept best describes the nervous system's learned ability to perceive joint position without visual input?
- Kinesthesia
- Proprioception (Correct answer)
- Nociception
- Interoception
Correct answer: Proprioception
Proprioception is the sense that allows the nervous system to perceive joint position and movement, which FRC training seeks to enhance throughout the full range of motion.
Question 4: In FRC, why is passive range of motion considered less neurologically valuable than active range of motion?
- Passive ROM damages cartilage more readily
- Passive ROM does not require nervous system engagement or motor control (Correct answer)
- Passive ROM only works on ligaments
- Passive ROM increases cortisol levels
Correct answer: Passive ROM does not require nervous system engagement or motor control
Passive ROM is moved by an external force and does not require the nervous system to actively control the joint, making it less effective for building functional motor maps.
Question 5: What is 'motor control' as it applies to FRC joint training?
- The ability to lift maximum loads at a joint
- The nervous system's capacity to produce precise, coordinated joint movements (Correct answer)
- The use of electrical stimulation to contract muscles
- A type of manual therapy technique
Correct answer: The nervous system's capacity to produce precise, coordinated joint movements
Motor control in FRC refers to the nervous system's ability to precisely coordinate and execute joint movements, which is developed by training through full ranges of motion with active muscular effort.
Question 6: According to FRC principles, what happens to ranges of motion that are not regularly accessed by the nervous system?
- They become stronger over time
- The nervous system progressively loses control and awareness of those ranges (Correct answer)
- They develop increased connective tissue density
- They remain unchanged indefinitely
Correct answer: The nervous system progressively loses control and awareness of those ranges
The nervous system follows a 'use it or lose it' principle, reducing neural maps and motor control for joint ranges that are not regularly trained.
