The researchers intend to monitor the workers conditions with regular medical examinations over a five year period, and if possible, to investigate the effect of a short daily program of yoga- including pawanmuktasana, surya namaskara, nadi shodhana pranayama and relaxation, on their ongoing health status.
Yoga practices are presently used mainly in rehabilitational medicine in Czechoslovakia, probably because there are relatively good conditions for its use. Exercise has been traditionally used in this field, so that yoga fits readily into this framework. In addition, rehabilitation departments have gymnasiums that can be readily used for yoga practices. Some rehabilitation nurses are personally interested in yoga, and are transferring their experience into therapy for their patients.
Very encouraging results are reported in yogic rehabilitation treatment of vertebrogenic diseases, including postural deformity and scoliosis. *1, *2, *3 Yoga practices are also used in balneology (spa treatment)*4, and also with surprisingly favourable results, in the rehabilitation of children with minimal brain dysfunction.*5 Simple yoga practices have also been applied in the rehabilitation of tuberculosis patients.
Isolated, but very interesting communications have also been made in application of yoga therapy in other fields of medicine, including gerontology (old age medicine)*6, psychiatry*7, matrimonial counselling service*8, cure of smoking*9, and oncology (cancer therapy).*10
Practical education of rehabilitation staff is very important, to ensure correct application of suitable yoga practices. The cited works above are of a preliminary character, and in order that the confidence of medical men in yoga will increase, good studies of yoga therapy must appear in the respected medical journals. At the present time it is only those doctors who have had favourable personal contact with yoga for their own health and that of their patients, who are convinced about the great medical value of yoga. Most medical men, who have had no such experience of yoga, have an understandably reserved approach to it. In this light, both theoretical and practical papers,*11 are important, as they create a suitable background for practical use of yoga therapy on a wider scale in our communities.
Similarly, yoga is an excellent means of disease prevention and more papers can be expected in this regard.*12, *13 For example, a comparison of the incidence of specific diseases in men who practise yoga and a control group who do not, would be very interesting.
Further interesting and promising areas for study are the effects of yoga on psychosomatic (stress-related) diseases and alcoholism.
The medical use of yoga is in its infancy in our country, but it seems assured of an important role in medicine on a larger scale.
The potential of yoga to relieve suffering and frustration, and lead a society and its individuals towards better physical, mental and emotional health demands full investigation. Scientific proof for yoga's effectiveness must be forthcoming, even if the exact scientific mechanisms and modes of action of the practices proves difficult at the present time.
