What is the purpose of balance boards or perturbation training in rehab?

• A. To immobilize joints during rehab.
• B. To increase cardiovascular endurance.
• C. To challenge the neuromuscular system and improve postural control and stability.
• D. To strengthen respiratory muscles.

Answer: (C)

Balance boards and perturbation training focus on how the body senses and responds to instability. By creating challenging, unstable surfaces or unexpected shifts, the nervous system must rapidly integrate sensory input from the eyes, inner ear, and muscles and adjust muscle activity to maintain or regain balance. Over time, this enhances proprioception, coordination, and the timing of muscle responses across the ankle, knee, and hip, leading to improved dynamic postural control and stability. This translates to better balance during real-life tasks and athletic activities, and also helps reduce risk of re-injury.

This approach isn’t about immobilizing joints, boosting cardiovascular endurance, or strengthening respiratory muscles, which are addressed by other training methods.
