Complex regional pain syndrome (CRPS) is a chronic, debilitating, neuropathic pain condition which is often misdiagnosed, difficult to manage, and lacks proven methods for remission. Most available methods provide some relief to a small percentage of patients. Recent FDA approval and superiority of the Nevro Senza 10-kHz high frequency (HF10) spinal cord stimulation (SCS) therapy over traditional low-frequency spinal cord stimulation for treatment of chronic back and leg pain may provide a new interventional therapeutic option for patients suffering from CRPS. We provide a case report of a 53-year-old Caucasian woman who suffered with CRPS in the right knee and thigh for over 7 years. Implantation of the HF10 device provided over 75% relief of pain, erythema, heat, swelling, and tissue necrosis to the entire region within 1 month of treatment. Because the HP10 therapy provides pain relief without paresthesia typical of traditional low-frequency, this system may provide relief for patients suffering from chronic pain.

Previous literature has suggested that reflex sympathetic dystrophy, also known as complex regional pain syndrome (CRPS) type 1, is a relatively common finding after a stroke. However, much of this data was obtained before patients routinely re ceived early intensive inpatient rehabilitation. The purpose of this study is to reeval uate the incidence of CRPS type 1 following an acute first stroke. Subjects admitted to an acute rehabilitation setting for stroke with no other concomitant neurologic or orthopedic injuries between October 1, 1996, and May 31, 1997, were studied. At admission and once a week until discharge, subjects were evaluated for shoulder pain, decreased passive range of motion of the shoulder, wrist/hand pain, edema, and skin changes. If three of these five criteria were positive, the subjects underwent a triple- phase bone scan (TPBS). Bone scan findings consistent with CRPS type 1 were taken as confirming the diagnosis. Of 64 subjects, 13 underwent bone scans, with only one positive result. Thus our study revealed a 1.56 percent incidence of CRPS type 1 fol lowing a first stroke. This incidence is much lower than the historically accepted 12.5 percent. We speculate that this low figure is related to early comprehensive rehabili tation that included proper upper extremity positioning and early mobilization with sensory stimulation.

Abstract Background and Purpose. Complex regional pain syndrome type II (CPSII) is a painful condition that develops following a nerve injury. Although transcutaneous electrical nerve stimulation (TENS) relieves the pain of CPSII, the stimulation parameters that would best prevent the development of the condition are not known. The purpose of this study was to compare the ability of several different stimulation strategies to reduce the development of allodynia. Subjects. Sprague-Dawley rats were used in the study. Methods. A chronic constriction injury (CCI) to the right sciatic nerve was used to induce allodynia. Two groups of CCI rats received high-frequency TENS to the lumbar paravertebral region with electrodes positioned on the skin overlying either the right or left paraspinal musculature. Two additional groups of CCI rats received low-frequency TENS to acupuncture points in the right or left hind limbs. A fifth group of CCI rats received no TENS intervention. Thermal and mechanical pain thresholds were assessed in the right hind paw before and 12 days after the CCI surgery. The TENS was delivered 1 hour per day beginning on the day of surgery. Results. Daily high-frequency TENS reduced the development of mechanical allodynia in CCI rats, and low-frequency TENS reduced the development of thermal allodynia, but only when TENS was delivered on the left side. Discussion and Conclusion. The results indicate that TENS delivered contralateral to a nerve injury best reduces allodynia development. Comprehensive reduction of allodynia development would require a combination of high- and low-frequency TENS intervention.

Dorsal root ganglion (DRG) stimulation is an effective treatment for chronic, refractory complex regional pain syndrome (CRPS). Routinely, the placement of a DRG stimulator lead is based on established anatomical knowledge of dermatomes. In patients with lumbosacral transitional vertebral anatomy, dermatome maps are not dependable due to dermatomal variance. This can make correct placement of stimulator leads challenging as the supposed target may not actually be responsible for sensing the painful area. We present a case of a 60-year-old woman with CRPS and lumbarization of the S1 vertebral body (presence of 6 lumbar vertebrae and 4 sacral vertebrae) who failed a DRG stimulator trial after using conventional dermatome maps to identify target DRGs assuming that the nerve exiting below L6 corresponded to the S1 dermatome. Following the failed trial, sensory stimulation of the DRG via radiofrequency stimulation was used to accurately map dermatomes leading to a successful DRG stimulation implant at a DRG level that differed from expected based on traditional dermatome maps. Thus, DRG stimulation may guide decisionmaking in regard to target stimulation in patients with abnormal vertebral anatomy.
