What does the amplitude of sEMG signals represent?

• The strength of electrical activity

• The duration of muscle contraction

• The temperature of the muscle

• The speed of muscle recovery

In which field can sEMG be used for injury prevention?

• Culinary arts

• Sports science

• Music therapy

• Fashion design

What is a limitation of surface EMG?

• Requires surgical intervention

• Complex setup

• Limited depth detection

• High cost

What is one benefit of using sEMG?

• Limited applications

• Invasive procedure

• Real-time monitoring

• Requires extensive training

If a patient’s sEMG readings show high amplitude but irregular timing, what might this indicate?

• The patient is not contracting the muscle
  
  

• The muscle is completely fatigued
  

• 
  There is poor neuromuscular coordination
  
  

• 
  The electrodes are too close together
