According to a double-blind crossover clinical study by the Basildon and Thurrock University Hospitals, 1 kHz provides excellent pain relief, with significantly less energy than higher frequencies.
Dr. Simon Thomson, MBBS, chief investigator and consultant in pain medicine and neuromodulation at Basildon and Thurrock University Hospitals in Essex, England states that frequencies higher than 1 kHz provided noadditional pain relief despite using significantly more power.
This finding suggests that if pain relief can be achieved at a lower neural dose, there are clinical advantages for the patient in terms of lower power consumption, less frequent recharging, and lower risk of neural damage.
This clinical trial highlights that neural dosing is key in optimizing therapy at each frequency and providing pain relief requires proper waveform to the right area. Timothy Deer, MD, president and CEO of the Center for Pain Relief, in Charleston, W.Va. said: "The theory is that if you overdose people with too much electricity, the patient may get tolerant to the effect of the electrical message". Dr. Deer added: "By controlling dosing this could avoid neural damage."
Based on these findings, a fully programmable pulse generator that can deliver the right pulse waveforms and frequencies to multiple areas of pain would be ideal for the most efficient and effective personalized therapy modalities.
