title: Improvement by picoTesla range magnetic fields of perceptual-motor performance and visual memory in a patient with chronic progressive multiple sclerosis.
abstract: The occurrence of cognitive deficits in multiple sclerosis (MS) has been recognized since 1877 when Charcot first observed "enfeeblement of memory." It is now recognized that visuoperceptive and visuomotor deficits commonly occur in MS patients particularly in those with a chronic progressive course of the disease. Using various drawing tests as markers of constructional performance, we reported recently that treatment with picoTesla range magnetic fields (MF) rapidly improved visuoperceptive and constructional abilities in patients with MS. We now report a 58 year old man with a 37 year history of chronic progressive MS in whom external application of MF in the picoTesla range produced rapid improvement of neurologic symptoms including walking, balance, sensory symptoms, and bladder functions. The patient's recovery was associated with a significant improvement in perceptual-motor functions as demonstrated on the Rey-Osterrieth Complex Figure and the Trail Making tests. Specifically, the patient demonstrated a 41% improvement over pretest values on copying the Complex figure and a 72% improvement in recall of the figure immediately after MF treatment. A further 4% improvement on copying the figure and a 27% improvement on recall was demonstrated 24 hours later. On the Trail Making test the patient demonstrated an overall improvement of 39% in Part A of the test and a 24% improvement in Part B of the test 24 hours after application of MF. These findings confirm the beneficial effects of picoTesla range MF in the treatment of MS and demonstrate the unique efficacy of this treatment modality in improving some of the cognitive deficits of the disease.
