Hi This is the conclusion posting about my use of EMS( electro muscle stimulation )/TENS machine . I had three objectives in trying this machine . 1) back and neck stiffness relief 2) Dyskinesia relief 3 ) General PD symptom relief I used both the muscle strengthening and the muscle toning function on all the spinnal muscles of my back as well as the muscle toning function on the neck muscles . This produced a 50% improvement in stffness within 2 weeks . I was hoping that prolonged intensive treatement would would see contnuing improvement . This was not the case . There was no further improvement and it is possible that a lot of clicking in my back was as a result of this intense treatement .Moderating my use to two days a week instead of every day is coincident with a lessening of the clicking in my back . My PD symptoms are confined to the left side of my body . I often can suppress the end of dose dyskinesia by stimulating my left foot , provided the dyskinesia is not too severe . Varying the frequency and intesity of the stimulation increases the suppression . At times of strong dyskinesia nothing seems to make the leg stop its erratic movement . One of my chief aims with this machine was to see if I could parallel , some of the PD symptom improvements achieved with deep brain stimulation, with muscle stimulation . The EMS/TENS machine started to go erratic after a few hours continuous use . I will have to make a purpose built machine to test this possibility and intend to start this project as soon as my testing of chemicals is over . peace Alastair ( [log in to unmask] )
