What condition results from an imbalance in the tone of the sympathetic and parasympathetic systems?

The condition that arises from an imbalance in the tone of the sympathetic and parasympathetic systems is known as dysautonomia. This term refers to a dysfunction of the autonomic nervous system, which controls involuntary bodily functions such as heart rate, blood pressure, digestion, and more. When there is an imbalance, it can lead to a wide range of symptoms, including irregular heart rates, blood pressure fluctuations, gastrointestinal issues, and other bodily functions that rely on autonomic regulation.

Dysautonomia encompasses various disorders that can result from this autonomic imbalance, emphasizing its significance in understanding how the nervous system affects overall health. Recognizing this condition is crucial in chiropractic practice, as it can impact a patient's symptoms and areas of care.

The other options represent different concepts; dyskinesia refers to abnormal, uncontrolled movements; pathophysiology is the study of disordered physiological processes associated with disease; and myopathy generally refers to muscle diseases that affect function but do not specifically involve the autonomic nervous system's balance.
