In the acute intervention phase for GBS, which activity aligns with the recommended RPE of 2-4/10?

• A. High-intensity cardio
• B. Aggressive resistance training
• C. Respiratory therapy only
• D. Positioning and range of motion; gentle isometrics

Answer: (D)

In acute GBS, the focus is on light, tolerable activity that protects joints and muscles while conserving energy as nerves and muscles recover. An RPE of 2-4 out of 10 is considered very light effort—you should be able to talk in complete sentences without getting breathless or fatigued.

The option that aligns with this level of exertion combines positioning and range of motion with gentle muscle activation. Positioning and ROM help maintain joint flexibility, prevent contractures from prolonged inactivity, and promote circulation—all without adding significant strain. Gentle isometrics activate muscles at a low intensity without dynamic movement or heavy loading, providing safe neuromuscular engagement that supports circulation and proprioception without overtaxing the patient.

Why the other approaches aren’t the best fit here: high-intensity cardio would push effort into a heavier range, increasing fatigue and autonomic stress; aggressive resistance would demand more energy and could risk overexertion and nerve or muscle irritation; and focusing on respiratory therapy alone omits the important benefits of maintaining ROM and joint health.
