Case Reports
Percutaneous peripheral nerve stimulation for chronic pain in subacromial impingement syndrome: a case series.
The objective of this study was to determine the effect of peripheral nerve stimulation (PNS) on pain reduction for those with refractory subacromial impingement syndrome (SIS) and to evaluate the association with reduced disability, impairment, and safety. Our hypotheses are that PNS will be associated with a reduction in pain, impairment and disability, and improvement in quality of life while demonstrating safety. ⋯ Intramuscular PNS for chronic shoulder pain due to SIS is a safe treatment associated with pain reduction, lower pain interference with activities of daily living, reduced disability, and improved shoulder abduction. Pain reduction is maintained for at least 12 weeks after treatment.

To quantify changes in pain and somatosensory function in patients with central poststroke pain (CPSP) syndrome following five sessions of repetitive transcranial magnetic stimulation (rTMS). ⋯ Five sessions of open-label rTMS provided analgesia and improved thermal sensibility. The correlation of reduction of detection threshold for warmth and pain relief suggest that the effect of rTMS may be mediated via circuitries that share the processing of noxious and thermal signals, such as the insula and the somatosensory and anterior cingulate cortices. QST may have a role in the assessment of patients with neuropathic pain for suitability for rTMS treatment and is likely to add to our understanding of how rTMS induces pain relief.
