Objective : Radiofrequency (RF) medial branch neurotomy is an effective management of lumbar facet syndrome. However, pain may recur after period of time. When pain recurs, it can be repeated, but the successful outcome and duration of relief from repeated procedures are not clearly known. The objective of this study was to determine the success rate and duration of pain relief from repeated radiofrequency medial branch neurotomy for lumbar facet syndrome. Methods : A retrospective review of medical records was done on 60 consecutive patients, from March of 2006 to February of 2009, who had an initial successful RF neurotomy but subsequently underwent repeated procedures due to recurrence of pain. All procedures were done in carefully selected patients after at least two responsive medial branch nerve blocks. C-arm fluoroscopic guide, impedance, sensory and motor threshold monitoring tools were used for the precise placement of electrodes. Responses of repeated procedures were compared with initial radiofrequency neurotomy for success rates and duration of pain relief. Results : There were 48 females and 12 males. Mean age was 52.4 years (range, 26-83). RF medial branch neurotomy was done on one side in 38 and both sides in 22 patients, each covering at least three segments. Average visual analog scale at last procedure was 6.8. Twelve patients had previous lumbar operations, including 4 patients with instrumentations. Fifty-five patients had two procedures and five patients had three procedures. Mean duration of successful pain relief (> 50% of previous pain for at least 3 months period) after initial radiofrequency neurotomy was 10.9 months (range, 3-28) in 51 (85%) patients. From repeated procedures, successful pain relief was seen in 50 (91%) patients with average duration of 10.2 months (range, 3-24). Five patients had third procedure, which was successful in 4 (80%) patients with mean duration of 9.8 months (range, 5-16). This was not statistically different from initial results. There were no permanent neurological complications from the procedures. Conclusion : Results of this study indicate that the frequency of success and durations of relief from repeated RF medial branch neurotomy for lumbar facet syndrome are similar to initial results that provided relatively prolonged period of pain relief without major side effects Each procedure seems to provide successful pain relief for about 10 months in more than 85% of carefully selected patients when properly done.
Background: The efficacy of nerve block on the progression of herpes zoster still remains controversy. The purpose of this study was to evaluate the efficacy of epidural blockade on the pain course of acute herpes zoster. Methods: Among 75 patients admitted with acute herpes zoster, 40 patients were treated with acyclovir and epidural block (epidural group), 35 patients were treated with acyclovir only (no block group). Follow up with patients was done for up to 3 months, either at the outpatient department or by telephone. The days required for pain relief were compared. We also investigated the factors associated with outcome. Results: Though statistically insignificant, patients in the epidural group tended to have faster pain relief. Patients with shorter symptom duration experienced significantly faster pain relief. But other factors such as sex, age, involved dermatome and other coexisting diseases (cancer, diabetes mellitus) were not associated with the outcome in this study. Conclusions: Though patients with epidural block leaded to have taster pair relief, more studies with larger patient population may be needed to confirm the efficacy of epidural block on herpes zoster.
Background: Epidural steroid injection is an established treatment modality for intervertebral disc prolapse to radiculopathy. In cases where two levels of radiculopathy are present, two separate injections are warranted. Herein, we present our experience of management of such cases with a single epidural injection of local anaesthetic, tramadol and methylprednisolone, and table tilt for management of both radiculopathies. Methods: 50 patients of either sex aged between 35-65 years presenting with features of cervical and lumbar radiculopathic pain were included and were subjected to single lumbar epidural injection of local anaesthetic, tramadol and methylprednisolone, in the lateral position. The table was then tilted in the trendelberg position with a tilt of 25 degrees, and patients were maintained for 10 minuted before being turned supine. All patients were administered 3 such injections with an interval of 2 weeks between subsequent injections, and pain relief was assessed with a visual analogue scale. Immediate complications after the block were assessed. Results: Immediate and post procedural complications observed were nausea and vomiting (20%), painful injection site (4%), hypotension (10%) and high block (4%). Pain relief was assessed after the three injections by three grades: 37 (74%) had complete resolution of symptoms; 18% had partial relief and 8% did not benefit from the procedure. Conclusions: This technique may be used as an alternative technique for pain relief in patients with unilateral cervical and lumbar radiculopathies.
In recent years the use of epidural opiates has increased and although this method of pain relief has shown good results in clinical practice It is still subject to certain drawbacks, the most serious of which appears to be delayed respiratory depression. Since ketamine administered systemically is unlikely to produce respiratory depression it seemed worthwhile to investigate the possibility of exploiting the potent analgesic property to ketamine by its epidural administration. The analgesic effect of ketamine 4 mg, administered epidural space, was evaluated. The duration of pain relief varied from less than 3 hours in 20% to over 24 hours in 30% of the cases. In 62.5% of the cases pain relief exceeded 6 hours. There was no evidence of respiratory depression, and there no postoperative neurologic sequelae. The present results indicated the need for further studies to compare the efficacy and safety of epidural ketamine with the response to epidural opioids for the relief of postoperative pain.
The aim of this paper is to design and evaluate calf braces that are equipped with Electrical Muscle Stimulation (EMS) modules. These braces are intended to alleviate calf pain in PARA Taekwondo athletes. The paper also seeks to assess the effects of different textile electrode designs. PARA Taekwondo participants are at a heightened risk of injuries and pain due to the nature of this exercise, which is designed for individuals with disabilities. Additionally, there is a significant risk of strain on the lower limb muscles in PARA Taekwondo compared to regular Taekwondo. To address this issue, calf taping methods are commonly used. In this study, we develop calf EMS protective gear and aim to examine the effects of different textile electrode designs inspired by taping methods. We evaluate the differences in the effects of three different textile electrode designs through visual analog scale (VAS) and range of motion (ROM) measurements. The results show that EMS protective gear has the potential to reduce calf pain among PARA Taekwondo athletes, with electrode designs inspired by kinesiology taping providing the most effective pain relief. This research suggests that these findings may be applicable to other sports disciplines, body areas, and everyday pain relief scenarios.
Background: Response to diagnostic blocks does not consistently predict the outcome of interventional facet denervation. We investigated the relationship between pain relief by the percutaneous radiofrequency denervation of the lumbar zygapophysial joints with the result of facet joint diagnostic local anesthetic injection in patients with back pain originating from the lumbar zygapophysial joint. Methods: There were 35 patients enrolled, with ranging in age from 25 to 76 years ($52.6{\pm}12.7$ years, mean ${\pm}$ SD). We studied 7 men (20%) and 28 women (80%). All patients underwent double diagnostic block of $L_{3/4}$, $L_{4/5}$ and $L_5-S_1$ facet joint with 0.5% bupivacaine. The 35 patients fell into the following group. (1) Group A (n = 16): those who felt clear relief (pain free with Likert scale) from the double diagnostic block (2) Group B (n = 19): 11 patients who were always equivocal in their response to the double diagnostic block and 8 patients who were either pain free or equivocal in their response to the double diagnostic block. All 11 patients were done the facet joint denervation. The effect on the pain was evaluated with 4 point Likert scale 1, 6 and 12 weeks after the procedure. We evaluated the relationship between the pain response to diagnostic block and the pain relief with facet joint denervation. Results: Significant correlation was observed between the response to diagnostic block and pain relief with facet denervation (P < 0.05). We found no correlation between the categories of spinal operation and pain response to facet denervation (P value > 0.05). Conclusions: A satisfactory result of lumbar facet joint denervation can be obtained in many patients, especillay in patients whose pain were relieved by the diagnostic double facet joint block. It may be said that facet joint denervation for mechanical low back pain using radiofrequency thermocoagulation is a safe, easy, and repeatable technique.
Objectives : This study was designed to evaluate effects of 'Soyeum' on cancer patients accompanied by pain. Materials and Methods : We retrospectively analyzed the medical records of 9 patients accompanied by pain who had been injected with 'Soyeum' for over 14 days continuously in East-West Cancer Center of Oriental Hospital of Daejeon University from June 2002 through august 2002. Results : The statistical significance between the pre-treatment and post-treatment results (Changes of Cytokine Level, QOL, BPQ and Pain relief after pain management) were analyzed. Analysis of cytokines (IL-12, IFN- ) level showed that the percentage of increase of lL-12 is $60\%$, IFN- is $60\%$. Analysis of QOL showed that the percentage of maintenance and improvement is $77.8\%$. $55.5\%$ of the patients reported a 'worst pain' intensity score of 3 or greater, $44.5\%$ reported a 'least pain' intensity score of 2 or greater, and $66.7\%$ reported 'average pain' intensity score of 2 or greater. $33.3\%$ of the patients were in pain at the time of interview and $22.2\%$ had a current intensity score of 2 or greater. Analysis of pain relief after pain management showed that the percentage of pain relief score of 2 and 3 is $55.6\%$. The data was expressed as Mean SE by using descriptive statistics. Statistical significance examined by using paired t-test. Conclusions : It is suggested that 'Soyeum' has effects on pain of cancer patients, also expected that 'Soyeum' is useful to improve immunoactivity and for cancer patients

Percutaneous retrogasserian glycerol rhizolysis(PRGR) was performed in 43 patients, a total of 65 times, for the management of typical trigeminal neuralgia from 1987 to 1991. The age of patients was distributed between 19 and 87 years. According to sex 17 were male and 26 were female. Pure glycerol of 0.3-0.8 ml was injected into the Meckel's cave on the affected site. In 31 PRGR(Group I) that had cisternography to titrate the dose of glycerol, when treated, 26 G of these PRGR patients(83.9%) had relief of pain. There were recurrence of pain in 7PRGR (22.6%) and the average interval from the PRGR to recurrence of pain in 7 PRGR(22.6%) and the average interval from the PRGR to recurrence of pain was 16.9 months. In 34 PRGR(Group II) of which bupivacaine was injected to titrate the dose of glycerol, 29 PRGR(85.3%) had relief of pain 80 howing treatment. There were recurrence of pain in 8 PRGR(23.5%) and the average interval from the PRGR to the recurrence of pain was 14.3 months. Finally of all procedures done(65 PRGR), 55 PRGR(84.6%) had relief of pain. There were recurrence of pain in 15 PRGR(23.1%) and the average interval from the PRGR to recurrence of pain was 15.5 months. There was no significant difference between the two groups in the rate of pain relief. There were conjunctival irritation(3 cases), headache(2), vomiting(3), hematoma(2), and herpes simplex(3) as transient complications after PRGR. Corneal ulceration and anesthesia dolorosa did not develop in any cases.

Objective : Brachial plexus injury can produce a intractable chronic neuropathic pain. This study was undertaken to assess the long term outcome of microsurgical dorsal root entry zonotomy[MDT]. Methods : Between October 1997 and December 2002, 21 patients received MDT because of a intractable pain resulting from brachial plexus injury. Of these, 19 patients were followed for more than 2 years. Fourteen of 19 patients were male and patient ages ranged from 22 to 69 years. Mean pain duration was 36.8 months and all patients had severe pain of $9{\sim}10$ visual analogue scale. To achieve complete destruction of abnormal dorsal horns, thermocoagulation of the posterolateral sulcus were performed and careful gluing was done to prevent postoperative adhesion and pain recurrence. Results : Of the 19 patients, 15 patients had excellent [>75% reduction in pain] and good [$51{\sim}75%$ pain relief] results in a average postoperative period of 4.1 years. One patient had a poor [less than 25% pain relief] result. Three patients were considered to have a fair result [$26{\sim}50%$ pain relief]. Postoperative complications were 2 transient ipsilateral ataxia and 1 CSF fistula that resolved without surgical revision. Conclusion : These results indicate that MDT provides excellent long-term pain relief in medically intractable chronic neuropathic pain following brachial plexus injury without significant complications.

Spondylolysis, also known as stress injury of pars interarticularis, is a common cause of back pain in athletes, particularly children and young adults. Repeated minor traumas during flexion and extension of the spine are thought to result in bony failure due to excessive bone resorption. These lesions are common in the low back, with the majority found at the L5 vertebra. In the majority of cases of spondylolysis, non-operative treatments are recommended, such as NSAIDs, physiotherapy and bracing. Only if symptoms do not respond to conservative treatments should surgical intervention be considered. Recently, pars interarticularis injections for diagnostic and therapeutic purposes have been found to allow significant pain relief from spondylolysis for long periods. Here, the case of a 57-year-old man with spondylolysis, who suffered from back pain, which was not relieved by an epidural steroid injection, but in whom pars interarticularis injections of local anesthetic and steroid induced complete transient pain relief, following by moderate long-term relief, is presented.
