Final answer:
Surface EMG and biofeedback enable individuals to gain voluntary control over involuntary bodily processes through visual or auditory feedback, which can be beneficial in treating various health conditions.
Step-by-step explanation:
One advantage of Surface EMG (electromyography) and biofeedback is their ability to aid in the development of strategies for achieving voluntary control over involuntary bodily functions. This control is facilitated by providing visual or auditory feedback based on measurements of neuromuscular and autonomic activity.
An example of this is in the treatment of conditions like tension headaches, high blood pressure, and other stress-related issues, where biofeedback has been applied with success.
