1) Statistics of electrotherapies in Japan (1961-1966): Questionnaires concerning on clinical application of low frequency electrotherapy were sent to 142 big clinics in all over the Japan. Answers were obtained from 70 clinics. The total number of the cases was 8973 who were treated for past five years.
It is clarified from the analysis of this questionnaires and answers that low frequency electrotherapy have been applyed in many clinics by following the basis of neuro-physiological principles and some improvements were noticed on 56.4% of 8858 cases.
2) Statistics of electrotherapy in our clinic during past five years:
The principle in the treatment of the nervous system in our clinic were as follows;
a) The diseases in the muscle and peripheral nerve fibers: They will be treated by the third effect of polarization.
b) The disease in neuro-muscular junction: It will be treated by the post-tetanic potentiation on neuro-muscular junction.
c) The disease in the spinal synapses:
It will be treated by two theoretical bases; firstly post-tetanic potentiation on spinal mono-synaptic reflex and secondly the third effect of spinal polarization on the reflex action.
3) Therapeutic application of low frequency current on progressive muscular dystrophy:
Recent advancement in electrotherapy on progressive muscular dystrophy in our clinic was reported in the view point of electromyography and biochemistry. The best result was gained by the administration of post-tetanic potentiation on the spinal mono-synaptic pathway.
4) Several problems in future:
The size and shape of electrode, wave-form, amplitude modulation, frequency modulation, telemetry, mechanical vibration, electrical narcosis, and heart and bladder stimulation with pace maker and so on were discussed.
