Effect of weak electromagnetic fields on body image perception in patients with multiple sclerosis

Cerebellar ataxia is one of the most disabling symptoms of multiple sclerosis (MS) and also one of the least responsive to pharmacotherapy. However, cerebellar symptoms often improve dramatically in MS patients by brief, extracerebral applications of picotesla flux electromagnetic fields (EMFs). This report concerns two MS patients with chronic disabling ataxia who experienced rapid improvement in gait and balance after receiving a series of treatments with EMFs. To assess whether improvement in cerebellar gait is accompanied by changes in body image perception, a parietal lobe function, both patients were administered the Human Figure Drawing Test before and after a series of brief treatments with EMFs. Prior to application of EMFs these patients' free drawings of a person showed a figure with a wide-based stance characteristic of cerebellar ataxia. After receiving a series of EMFs treatments both patients demonstrated a change in body image perception with the drawings of the human figure showing a normal stance. These findings demonstrate that in MS improvement in cerebellar symptoms by pulsed applications of picotesla EMFs is associated with changes in the body image.
