Austria | A study involving the Medical University of Vienna shows that the effectiveness of transcutaneous spinal cord stimulation depends heavily on the type of electrical waveform used. Researchers found that commonly used high frequency waveforms do not improve therapeutic outcomes in neurorehabilitation and may even reduce effectiveness in some cases.The study revealed that high frequency pulses increase stimulation thresholds, meaning stronger electrical currents are needed to achieve the same effect. This can reduce efficiency and limit the activation of the nerve fibres responsible for improving spinal cord function. The research also highlights that different regions of the spinal cord respond differently, challenging earlier assumptions about uniform treatment approaches.These findings suggest that simpler and more evidence based stimulation methods may be more effective for future neurorehabilitation treatments and device development.
