Which sign involves functions to halt forceful active movements when resistance is removed?

• A. Involuntary oscillatory movement resulting from alternate contractions of muscle groups
• B. Check reflex/factor
• C. Rhythmic eye movements
• D. Functions to halt forceful active movements when resistance is removed

Answer: (D)

The sign being described tests the motor system’s ability to brake or stop a deliberate, forceful movement the moment external resistance is removed. When you remove the resistance, a well-functioning motor system should terminate the action promptly rather than let it overshoot or continue. That precise halting of movement on release of resistance is what this sign captures, making it the best choice.

Other phenomena describe different motor or ocular behaviors. Involuntary oscillations from alternating muscle contractions point to tremor, which is a repetitive, rhythmical movement not specifically about stopping when resistance is released. Rhythmic eye movements refer to nystagmus, a distinct ocular motor issue. The reflex-related option involves a reflex response rather than the voluntary halting of a forceful movement upon resistance release.
