Abstract Background Complex regional pain syndrome (CRPS) is a chronic disabling painful disorder with limited options to achieve therapeutic relief. CRPS type I which follows trauma, may not show obvious damage to the nervous structures and remains dubious in its pathophysiology and also its response to conservative treatment or interventional pain management is elusive. Spinal cord and dorsal root ganglion stimulation (SCS, DRGS) provide good relief, mainly for causalgia or CRPS I of lower extremities but not very encouraging for upper extremity CRPS I. we reported earlier, a case of CRPS I of right arm treated successfully by wireless peripheral nerve stimulation (WPNS) with short term follow up. Here we present 1-year follow-up of this patient. Objective To present the first case of WPNS for CRPS I with a year follow up. The patient had minimally invasive peripheral nerve stimulation (PNS), without implantable pulse generator (IPG) or its accessories. Case report This was a case of refractory CRPS I after blunt trauma to the right forearm of a young female. She underwent placement of two Stimwave electrodes (Leads: FR4A-RCV-A0 with tines, Generation 1 and FR4A-RCV-B0 with tines, Generation 1) in her forearm under intraoperative electrophysiological and ultrasound guidance along radial and median nerves. This WPNS required no IPG. At high frequency (HF) stimulation (HF 10 kHz/32 μs, 2.0 mA), patient had shown remarkable relief in pain, allodynia and temperature impairment. At 5 months she started driving without opioid consumption, while allodynia disappeared. At 1 year follow up she was relieved of pain [visual analogue scale (VAS) score of 4 from 7] and Kapanji Index (Score) improved to 7–8. Both hands look similar in color and temperature. She never made unscheduled visits to the clinic or visited emergency room for any complications related to the WPNS. Conclusions CRPS I involving upper extremity remain difficult to manage with conventional SCS or DRGS because of equipment related adverse events. Minimally invasive WPNS in this case had shown consistent relief without any complications or side effects related to the wireless technology or the technique at the end of 1 year. Implications This is the first case illustration of WPNS for CRPS I, successfully treated and followed up for 1 year.

Minimally Invasive Device

Blood sugar management is particularly critical in the neonatal intensive care unit where the incidence of hypoglycemia is high and patients run the risk of brain damage. The staff at most hospitals obtain glucose levels in infants by drawing blood from the heel, which is a cause for recurrent pain. Some infants undergo this procedure every 1–3hours for up to a few months. Our goal is to design a minimally invasive device that allows for real-time glucose monitoring in very low birth weight infants in the neonatal intensive care unit (NICU). This glucose monitor will reduce the amount of pain and physiological stress on the infants, decrease the risk of hypoglycemia in neonates and reduce the workload on hospital staff. There is currently much room for emerging technologies in this market as it trends towards less pain and faster responses. The device should only slightly hinder the infant’s motion, be as painless as possible, and all materials used in contact with the body need to be biologically inert and cause no irritation or allergic reaction. The device will utilize a microneedle array to extract interstitial fluid and draw it through a hydrophilic polyurethane membrane and into a polarimetry chamber. Circularly polarized light will be passed through the chamber and the differential absorbance of left and right polarized light will be used to calculate the glucose concentration. A literature and patent review showed that each separate portion could be used in an effective device for minimally invasive, continuous glucose monitoring.

Rheo Probe is a minimally invasive device, implanted in the brain matter for patients in a coma following brain haemorrage or traumatic brain injuries to measure cerebral blood flow, intracranial pressure, temperature and oxygenation parameters. Nearinfrared sensors assess levels of tissue oxygenation as well as cerebral blood flow by measuring oxygenated and deoxygenated hemoglobin based on spectrometry.

Chronic Shoulder Pain

Background: Shoulder pain is a common condition, often refractory to treatment. Peripheral nerve stimulation (PNS) of the suprascapular nerve (SSN) can be efficacious in providing relief of shoulder pain while improving pain-related quality of life (QOL). The objective of this case report is to demonstrate the effectiveness of a minimally invasive wireless PNS in the treatment of chronic shoulder pain. Case Report: This 94-year old man presented with severe shoulder pain. He suffered from poliomyelitis as a child affecting his left leg, forcing him to use crutches to be ambulatory. He developed progressive right shoulder pain and was subsequently diagnosed with right glenohumeral osteoarthritis. The patient was treated semiannually for 4 years with corticosteroids injections and pain medication with minimal relief (7 out of 10 on the Visual Analog Scale [VAS]). A suprascapular block with lidocaine 2% resulted in significant pain reduction (1 out of 10 on the VAS). As a result, the patient opted for wireless PNS of the SSN via a minimally invasive procedure. Two weeks post implant, the patient reported no postoperative pain, and his chronic pain was rated 0 out of 10 even during movement. Reports of reduced pain were sustained throughout the 6 months of observation with subsequent improvements in QOL and functionality. Conclusion: Wireless neurostimulation of the SSN can be a very effective therapy option for the treatment of refractory, chronic shoulder pain as a result of glenohumeral osteoarthritis.
