Neuropsychological studies have demonstrated that multiple sclerosis (MS) is associated with various cognitive deficits and it has been suggested that it be considered a form of subcortical dementia. It is now recognized that visuoperceptive and visuomotor deficits commonly occur in MS patients particularly in those with chronic progressive course of the disease. The Human Figure Drawing Test has been employed in the assessment of generalized intellectual deterioration and specifically in the evaluation of visuoperceptive, visuospatial and visuoconstructional abilities in brain injured patients. I have demonstrated recently, on the basis of various drawing test, the external application of electromagnetic fields (EMFs) in the picotesla (pT) range intensity improved visuoperceptive and visuospatial functions in patients with MS. In the present communication I present five MS patients who were administered the Human Figure Drawing Test before and after a series of treatments with EMFs. Prior to application of EMFs four of these patients' drawings showed distortions, poor perspectives, impoverished facial expression, and lack of attention to details suggesting poor body image perception related to right posterior hemispheric dysfunction. In response to the administration of EMFs the group demonstrated improvement in motor disability which was associated with a striking improvement in the drawing particularly the drawings of the face the perception of which is localized to the right parietal lobe. These findings demonstrate that treatment with pT EMFs improves body image perception in MS patients thus corroborating previous observations which demonstrated this treatment modality to exert beneficial effects on cognitive functions in patients with MS.
神经心理学研究表明,多发性硬化症(MS)与多种认知缺陷有关,有人提出应将其视为皮质下痴呆的一种形式。现在人们认识到,视觉感知和视觉运动缺陷在MS患者中很常见,尤其是在那些患有慢性进行性疾病的患者中。人体绘图测试已被用于评估整体智力衰退,特别是用于评估脑损伤患者的视觉感知、视觉空间和视觉构建能力。我最近基于各种绘图测试证明,在皮特斯拉(pT)范围强度的电磁场(EMF)外部应用改善了MS患者的视觉感知和视觉空间功能。在本通讯中,我介绍了五名MS患者,他们在接受一系列EMF治疗前后接受了人体绘图测试。在应用EMF之前,这些患者中有四名的绘图显示出变形、视角不佳、面部表情贫乏以及对细节缺乏关注,这表明与右后半球功能障碍相关的身体形象感知较差。作为对EMF治疗的反应,该组患者的运动残疾有所改善,这与绘图的显著改善相关,特别是面部绘图,其感知定位于右侧顶叶。这些发现表明,pT EMF治疗可改善MS患者的身体形象感知,从而证实了先前的观察结果,即这种治疗方式对MS患者的认知功能有有益影响。
