Twenty five patients, 14 males and 11 females with an average age of 75years with chronic Low Back Pain were tested before, during, and after 10minutes transcutaneous electrical nerve stimulation. It is important to consider the effect of TENS on the autonomic function because the pain pathway and the ANS pathway are somehow correlated to each other. There is still controversy among researchers who have reported the effect of TENS on autonomic function. So the purpose of this study is to measure the effect of TENS on the ANS and to see the relation of the pain control mechanism and the change in the ANS. The results were as follows : 1) Systolic blood pressure between before and during the experiment was apt to be a little increased, but statistically there was no significant change(P>.05). 2) Systolic blood pressure between during and after 10 minutes the experiment was apt to be a little decreased, but statistically there was no significant change(P>.05). 3) Systolic blood pressure between before and after 10 minutes experiment was apt to be a little decreased, but statistically there was no significant change(P>.05). 4) Diastolic blood pressure between before and during experiment was apt to be a little increased, but statistically there was no significant change(P>.05). 5) Diastolic blood pressure between during and after 10 minutes experiment was significantly decreased(P<.05). 6) Diastolic blood pressure between before and after 10 minutes the experiment was apt to be a little decreased, but statistically there was no significant change(P>.05). 7) Heart rate between before and during the experiment was apt to be a little decreased, but statistically there was no significant change(P>.05). 8) Heart rate between during and after 10 minutes the experiment was significantly decreased(P<.05). 9) Heart rate between before and after 10 minutes the experiment was significantly decreased(P<.05). 10) Skin temperature between before and during the experiment was significantly increased(P<.05). 11) Skin temperature between during and after 10 minutes the experiment was apt to be a little increased, but statistically there was no significant change(P>.05). 12) Skin temperature between before and after 10 minutes the experiment was significantly increased(P>.05). 13) Respiratory rate between before and during the experiment was apt to be a little increased, but statistically there was no significant change(Pgt;.05). 14) Respiratory rate between during and after 10 minutes the experiment was apt to be a little decreased, but statistically there was no significant change(Pgt;.05). 15) Respiratory rate between before and after 10 minutes the experiment was apt to be a little decreased, but statistically there was no significant change(P>.05).

The purpose of this study was to investigate the relation between and subjective instability pain behavior (SIPB) and physical instability test(PIT) according to the presence of characteristic past histories(CPH) in people with chronic low back pain(CLBP). Forty CLBP subjects participated in this study. The presence of four characteristics past histories(long term history, traumatic experience, sports activities, neurologic sign) were examined. According to presence number(PN) of CPH, subjects were divided into 5 groups[group 1(PN:0): n=8, group 2(PN:1): n=8, group 3(PN:2): n=8, group 4(PN:3): n=8, group 5(PN:4): n=8]. After 16 items were examined for the SIPBs, then Seven PITs were conducted, and the results were scored. The SIPBs and PITs were compared according to the presence numbers of CPH, and the relation between them was analyzed. There was a significant difference(p<.05) in both SIPB scores and PIT scores in the comparison of groups according to the presence number of CPH. There was high positive correlation between the presence numbers of CPH and SIPB score(r=.819, p=.000) and PIT score(r=.606, p=.000). Also, there was a correlation between SIPB score and PIT score(r=.571, p=.000). Based on the findings in the present study, the presence of three or more CPH in people with CLBP may be a useful variable in the diagnosis of lumbar instability. The combined findings of the three variables such as CPH, SIPB, and PIT can improve the accuracy of lumbar instability diagnosis.

The purposes of this study were to analyze gait patterns of patients with chronic lumboscaral radiculopathy and to investigate gait parameters which can reflect a functional deficit in relation to the level of lumbosacral radiculopathy. The study population consisted of 25 patients of chronic lumbosacral radiculopathy and 25 healthy control subjects. Conventional physical examinations and three-dimensional gait analyses were performed on all participants. The data were analyzed using an independent sample t-test. The results were as follows: (1) In the patients' group, cadence, walking velocity, stride length and double support time were less than in the control group (p<.05). (2) In the patients' group, maximum flexion of hip, maximum flexion of loading response, maximum flexion of swing phase on the knee and maximum plantar flexion of pre-swing were less than the control group (p<.05). Using three-dimensional gait analysis, we could identify specific gait parameters to reflect a functional deficit related to the level of lumbosacral radiculopathy.

Background: We aimed to investigate the effect of epidural polydeoxyribonucleotide (PDRN) on mechanical allodynia and motor dysfunction in a rat model of lumbar foraminal stenosis (LFS). Methods: This study was conducted in two stages, using male Sprague-Dawley rats. The rats were randomly divided into eight groups. In the first stage, the groups were as follows: vehicle (V), sham (S), and epidural PDRN at 5 (P5), 8 (P8), and 10 (P10) mg/kg; and in the second stage, they were as follows: intraperitoneal PDRN 8 mg/kg, epidural 3,7-dimethyl-1-propargilxanthine (DMPX) (0.1 mg/kg), and DMPX (0.1 mg/kg). The LFS model was established, except for the S group. After an epidural injection of the test solutions, von Frey and treadmill tests were conducted for 3 weeks. Subsequently, histopathologic examinations were conducted in the V, S, P5, and P10 groups. Results: A total of 65 rats were included. The P8 and P10 groups showed significant recovery from mechanical allodynia and motor dysfunction at all time points after drug administration compared to the V group. These effects were abolished by concomitant administration of DMPX. On histopathological examination, no epineurial inflammation or fibrosis was observed in the epidural PDRN groups. Conclusions: Epidural injection of PDRN significantly improves mechanical allodynia and motor dysfunction in a rat model of LFS, which is mediated by the spinal adenosine A_2A receptor. The present data support the need for further research to determine the role of epidural PDRN in spinal stenosis treatment.

Individuals often report significant relief from pain and stress even after a single session of massage therapy; however, no previous studies have provided objective evidence supporting the effectiveness of a solitary massage therapy session. In the present study, we aimed to investigate the effectiveness of one-time treatment with a spinal thermal massage device reported to exert the same therapeutic effects as massage therapy in terms of pain reduction and stress relief. A man with chronic low back pain (LBP) underwent two rounds of experiments involving spinal massage treatment and bed rest, respectively. Pain was assessed using a visual analog scale, and heart rate variability (HRV) was measured in real-time to examine autonomic nervous system (ANS) activity. Blood samples were obtained at five points during each round of the experiment to examine changes in cortisol, epinephrine, and norepinephrine. Spinal massage significantly reduced pain and enhanced parasympathetic activity when compared with the bed rest condition. In addition, both epinephrine and norepinephrine levels were lower following spinal massage than following bed rest. These results are consistent with the reported effects of conventional massage therapy and support the effectiveness of one-time treatment using a spinal thermal massage device.

To present a case of cauda equina syndrome (CES) caused by chronic inflammatory demyelinating polyneuropathy (CIDP) which seemed clinically similar to Charcot-Marie-Tooth disease type1 (CMT1). CIDP is an immune-mediated polyneuropathy, either progressive or relapsing-remitting. It is a non-hereditary disorder characterized by symmetrical motor and sensory deficits. Rarely, spinal nerve roots can be involved, leading to CES by hypertrophic cauda equina. A 34-year-old man presented with low back pain, radicular pain, bilateral lower-extremity weakness, urinary incontinence, and constipation. He had had musculoskeletal deformities, such as hammertoes and pes cavus, since age 10. Lumbar spine magnetic resonance imaging showed diffuse thickening of the cauda equina. Electrophysiological testing showed increased distal latency, conduction blocks, temporal dispersion, and severe nerve conduction velocity slowing (3 m/s). We were not able to find genetic mutations at the PMP 22, MPZ, PRX, and EGR2 genes. The pathologic findings of the sural nerve biopsy revealed thinly myelinated nerve fibers with Schwann cells proliferation. We performed a decompressive laminectomy, intravenous IgG (IV-IgG) and oral steroid. At 1 week after surgery, most of his symptoms showed marked improvements except foot deformities. There was no relapse or aggravation of disease for 3 years. We diagnosed the case as an early-onset CIDP with cauda equine syndrome, whose initial clinical findings were similar to those of CMT1, and successfully managed with decompressive laminectomy, IV-IgG and oral steroid.

The objective of this survey was to understand the effect of the subjective degree and pain of urinary incontinence on the quality of life of the middle-aged women with the subjective symptom of urinary incontinence. A questionnaire was carried out to investigate the quality of life in relation to urinary incontinence for 114 patients of chronic musculoskeletal system from Feb. to May in 2010. Overall, the subjects responded that their quality of life was medium(($61.36{\pm}13.2$score) and the pain related to urinary incontinence was low back pain. The degree of pain was between the moderate and a little severe in the VAS (Visual Analogue Scale) range of 4 to 7. It was also shown that the action of the subjects was affected by urinary incontinence in forms of avoidance limitation and psycosocial effect. Since the survey showed that the urinary incontinence and pain substantially affect the quality of life of the middle-aged women, the result may provide basic information in developing a practical intervention program.

The purpose of this study was to compare acute and chronic LBP patient in twenties and forties, respectively by size measure paraspinal muscle (cross-sectional area; CSA). CSA of paraspinal muscle (psoas, multifidus, erector muscle) size was measured by free-handling technique of the picture archiving and communication system(PACS) using MRI at the level(lower end-plate of L4) in twenties(9 males, 10 females) and forties(9 males, 8 females) in acute and chronic LBP patient. The results of this study showed no significantly difference between acute and chronic LBP (p>0.05) in twenties patients. However, there was significant difference between acute and chronic LBP (p<0.05) in forties patients. Also, there was significant difference in paraspinal muscle CSA between chronic LBP patients in twenties and chronic LBP patients in forties (p<0.05). This study showed that paraspinal muscle atrophy was observed in forties with various cause, but Not chronic LBP patients in twenties. Accordingly it is required for chronic LBP patients in forties to minimize trunk muscle atrophy through immediate back muscle dynamic exercise and early functional activity.

Not all sciatica-like manifestations are of lumbar spine origin. Some of them are caused at points along the extra-spinal course of the sciatic nerve, making diagnosis difficult for the treating physician and delaying adequate treatment. While evaluating a patient with sciatica, straightforward diagnostic conclusions are impossible without first excluding sciatica mimics. Examples of benign extra-spinal sciatica are: piriformis syndrome, walletosis, quadratus lumborum myofascial pain syndrome, cluneal nerve disorder, and osteitis condensans ilii. In some cases, extra-spinal sciatica may have a catastrophic course when the sciatic nerve is involved in cyclical sciatica, or the piriformis muscle in piriformis pyomyositis. In addition to cases of sciatica with clear spinal or extra-spinal origin, some cases can be a product of both origins; the same could be true for pseudo-sciatica or sciatica mimics, we simply don't know how prevalent extra-spinal sciatica is among total sciatica cases. As treatment regimens differ for spinal, extra-spinal sciatica, and sciatica-mimics, their precise diagnosis will help physicians to make a targeted treatment plan. As published works regarding extra-spinal sciatica and sciatica mimics include only a few case reports and case series, and systematic reviews addressing them are hardly feasible at this stage, a scoping review in the field can be an eye-opener for the scientific community to do larger-scale prospective research.

The simultaneous occurrence of an intracranial and a spinal subdural hematoma (SDH) is rare. We describe a case of cranial SDH with a simultaneous spinal SDH. An 82-year-old woman visited the emergency room because of drowsiness and not being able to walk 6 weeks after falling down. A neurological examination showed a drowsy mentality. Brain computed tomography showed bilateral chronic SDH with an acute component. The patient underwent an emergency burr-hole trephination and hematoma removal. She exhibited good recovery after the operation. On the fourth postoperative day, she complained of low-back pain radiating to both lower limbs, and subjective weakness of the lower limbs. Spine magnetic resonance imaging revealed a thoracolumbosacral SDH. A follow-up spinal magnetic resonance imaging study that was performed 16 days later showed a significant decrease in the size of the spinal SDH. We discuss the pathogenesis of this simultaneous occurrence of spinal and cranial SDH.
