In agonist spasticity NMES, what is the recommended on/off setting to achieve fatigue?

• A. None because want to fatigue
• B. 1:1
• C. 1:2
• D. Continuous

Answer: (A)

When the goal is to fatigue an agonist spastic muscle with NMES, you push the muscle to its limit by keeping the stimulation continuous. Removing rest periods means the muscle works continuously, quickly exhausting its energy stores and metabolic reserves, which accelerates fatigue. Any on/off cycling provides recovery time for the muscle, allowing refueling and re-energizing, so it slows the progression toward fatigue. So the best approach is continuous stimulation with no off time.
