Pain perception in man after long term spinal cord stimulation
Journal of Neurology
|March 9, 1978
Summary
Electrical stimulation of the dorsal column did not significantly alter perception thresholds initially. However, long-term dorsal column stimulation increased sensory thresholds within the paresthesia area.
Area of Science:
- Neuroscience
- Sensory Perception
- Pain Management
Background:
- Dorsal column stimulation (DCS) is used for pain relief.
- Understanding DCS effects on sensory perception is crucial.
Purpose of the Study:
- To investigate the immediate and long-term effects of DCS on sensory perception thresholds.
- To assess the impact of DCS on somatosensory cortical potentials.
Main Methods:
- Electrical stimuli were used to determine perception thresholds.
- Somatosensory cortical potentials evoked by median nerve and vibration stimuli were recorded.
- DCS was applied during testing.
Main Results:
- Immediate electrical stimulation thresholds were unchanged by DCS.
- Long-term DCS significantly increased thresholds within the induced paresthesia area.
- Median nerve evoked potentials were unaffected by DCS.
- Vibration evoked potentials showed early component attenuation in some patients during DCS.
Conclusions:
- DCS does not acutely alter sensory perception thresholds.
- Long-term DCS may lead to sensory adaptation within the stimulated area.
- DCS has limited effects on early somatosensory cortical potentials.
