Conditions
Brief summary
In this study we seek to investigate the effect of varying pulse width and frequency on paresthesia perception. This study seeks to confirm the findings of Yearwood et al (2007, 2010) that varying pulse width can shift the focus of paresthesia and to provide the first findings on the effect of frequency on paresthesia perception. In addition, we will report on the interaction between pulse width and frequency changes.
Interventions
Obervation of the effect of the varying pulse duration and frequency on paresthesia perception. Participants are observed for several hours on one day only. The whole study is expected to be completed in 9 months.
