In MND, which type of exercise is discouraged due to fall risk and joint strain?

• A. Low-impact walking
• B. Moderate cycling
• C. High-impact exercises
• D. Resistance training with light weights

Answer: (C)

High-impact exercises are discouraged in motor neuron disease because they increase fall risk and place extra stress on the joints when strength, balance, and coordination are already compromised. Activities like running or jumping demand quick, powerful control and stable footing, which can be hard to maintain with weakness, proprioceptive changes, and fatigue. The result can be a higher chance of losing balance, tripping, or slipping, plus greater joint wear and soreness from the impact.

Safer options focus on protecting joints while maintaining function: low-impact walking at a comfortable pace on a stable surface preserves mobility and cardiovascular health without overloading the joints; stationary cycling reduces fall risk while helping build leg strength and endurance; resistance training with light weights supports muscle preservation and function when done with proper form and gradual progression. The plan should be tailored to the individual’s stage and symptoms, with guidance from a clinician or physical therapist to avoid overexertion.
