Direct medical costs after surgical or nonsurgical treatment for degenerative lumbar spinal disease: A nationwide matched cohort study with a 10-year follow-up.

OBJECTIVE: The demand for treating degenerative lumbar spinal disease has been increasing, leading to increased utilization of medical resources. Thus, we need to understand how the budget of insurance is currently used. The objective of the present study is to overview the utilization of the National Health Insurance Service (NHIS) by providing the direct insured cost between patients receiving surgery and patients receiving nonsurgical treatment for degenerative lumbar disease. METHODS: The NHIS-National Sample Cohort was utilized to select patients with lumbar disc herniation, spinal stenosis, spondylolisthesis or spondylolysis. A matched cohort study design was used to show direct medical costs of surgery (n = 2,698) and nonsurgical (n = 2,698) cohorts. Non-surgical treatment included medication, physiotherapy, injection, and chiropractic. The monthly costs of the surgery cohort and nonsurgical cohort were presented at initial treatment, posttreatment 1, 3, 6, 9, and 12 months and yearly thereafter for 10 years. RESULTS: The characteristics and matching factors were well-balanced between the matched cohorts. Overall, surgery cohort spent $50.84/patient/month, while the nonsurgical cohort spent $29.34/patient/month (p<0.01). Initially, surgery treatment led to more charge to NHIS ($2,762) than nonsurgical treatment ($180.4) (p<0.01). Compared with the non-surgical cohort, the surgery cohort charged $33/month more for the first 3 months, charged less at 12 months, and charged approximately the same over the course of 10 years. CONCLUSION: Surgical treatment initially led to more government reimbursement than nonsurgical treatment, but the charges during follow-up period were not different. The results of the present study should be interpreted in light of the costs of medical services, indirect costs, societal cost, quality of life and societal willingness to pay in each country. The monetary figures are implied to be actual economic costs but those in the reimbursement system instead reflect reimbursement charges from the government.

Rapid induction of clinical remission in SAPHO syndrome using high-dose Tripterygium glycosides: A case report.

RATIONALE: Synovitis, acne, pustulosis, hyperostosis, and osteitis (SAPHO) syndrome is a rare disease without standard treatments. Tripterygium wilfordii hook f (TwHF) is a traditional Chinese herb with anti-inflammatory effect, and 1.0 mg/(kg·d) dose of Tripterygium glycosides has been reported to significantly improve the disease activity of a SAPHO patient in a case report. However, the optimal dose of TwHF is still unclear. Here, we report the first case of SAPHO patient who achieved rapid remission in clinical symptoms after receiving 1.5 mg/(kg·d) dose of Tripterygium glycosides treatment. PATIENT CONCERNS: A 67-year-old woman noted palmoplantar pustulosis and pain in the anterior chest wall and waist. Bone scintigraphy demonstrated the typical tracer accumulation feature and magnetic resonance images showed bone marrow edema in lumbosacral vertebra. DIAGNOSES: The diagnosis was made by dermatological and osteoarticular manifestations and classical signs in bone scintigraphy in accordance with the diagnostic criteria proposed in 2012. INTERVENTIONS: Tripterygium glycosides was given with a primary dose of 1.5 mg/(kg·d) for 1 month and then reduced at a rate of 10 mg every 2 weeks until 1.0 mg/(kg·d) for a long-term maintenance. OUTCOMES: Fast-induced remission on clinical manifestations was achieved and magnetic resonance imaging abnormality was improved significantly. Additionally, no apparent side effects were observed. LESSONS: 1.5 mg/(kg·d) dose of Tripterygium glycosides seems to have fast-induced remission than 1.0 mg/(kg·d) with reliable safety. Besides, Tripterygium glycosides may also have a pharmacological effect of inhibiting osteolysis and enhancing bone strength.

Clinical research on the efficacy and safety of Bosinji for low back pain with radiculopathy caused by herniated intervertebral disc of the lumbar spine: A protocol for a multicenter, randomized, controlled equivalence trial.

BACKGROUND: A lumbar herniated intervertebral disc (LHIVD) is a common problem that usually causes low back pain and radiating pain. The effectiveness of Bosinji, one of the herbal medicines used for low back pain and radiating pain in patient with LHIVD, has been reported in several studies; however, little clinical evidence is available owing to the methodological limitations in previous studies. Hence, the present study aims to establish the clinical evidence regarding the efficacy and safety of Bosinji in improving pain, function, and quality of life in LHIVD patients. METHOD/DESIGN: This is a multicenter, open-label, randomized, controlled, and equivalence trial with 2 parallel arms. A total of 74 patients who have low back pain and radiating pain due to LHIVD will be recruited and randomly allocated to the experimental group and control group. The patients in the experimental group and control group will take 2.5 g of Bosinji granule (1.523 g of Bosinji extract) or Loxonin tablet (60 mg of loxoprofen) 3 times a day for 6 weeks. Additionally, both groups will receive the same acupuncture treatment once a week for 6 weeks as a concurrent treatment. Changes in the 100-mm visual analogue scale (VAS) for low back pain after 6 weeks from baseline will be assessed as the primary outcome. Furthermore, the 100-mm VAS for radiating pain, Oswestry disability index (ODI), Roland-Morris disability questionnaire (RMDQ), EuroQol 5 Dimensions 5 Levels (EQ-5D-5L), global perceived effect (GPE), and deficiency syndrome of kidney index (DSKI) will be used to evaluate secondary outcomes. Outcomes will be assessed at baseline and at 3, 6, and 10 weeks after screening. For the safety evaluation, laboratory examinations including complete blood count, liver function test, renal function test, blood coagulation test, inflammation test, and urine analysis will be conducted before and after taking the medications. DISCUSSION: The results of this trial will be used to establish clinical evidence regarding the use of Bosinji with acupuncture treatment in the treatment of patients with LHIVD. TRIAL REGISTRATION NUMBER: NCT03386149 (clinicaltrials.gov) and KCT0002848 (Clinical Research Information Service of the Republic of Korea).

A Comparison of the Abdominal and Lumbar Multifidus Muscle Size in Patients With Lumbar Spondylolisthesis and Healthy Patients at Rest and During Contraction Using Ultrasonography.

OBJECTIVE: Using ultrasonography, this study investigated the abdominal and lumbar multifidus muscle size in patients with lumbar spondylolisthesis compared with healthy patients at rest and during contraction. METHODS: This research was a nonexperimental, analytic case-control study. Ultrasound imaging was used to assess the thickness of the abdominal and lumbar multifidus muscles in 25 healthy patients and 25 patients with spondylolisthesis. For the purpose of this study, both men and women, aged 30 to 70 years, were recruited from physiotherapy clinics affiliated with the University of Social Welfare and Rehabilitation Sciences, Tehran, Iran. Measurements were taken at rest and during contraction. RESULTS: There was a significant difference in abdominal and lumbar multifidus muscle size between the healthy and spondylolisthesic groups, both at rest and contraction (P < .05 in all instances). No significant difference was found between the right and left for all measurements (P > .05). CONCLUSION: Patients with spondylolisthesis had smaller stabilizer muscle thickness at rest and during contraction compared with the healthy group.

Effect of Tai Chi Chuan on degeneration of lumbar vertebrae and lumbar discs in middle-aged and aged people: a cross-sectional study based on magnetic resonance images.

Objective Exercise has a positive effect on physical fitness. Tai Chi Chuan is a traditional Chinese aerobic exercise. We assessed the effect of Tai Chi on the degeneration of lumbar vertebrae and lumbar discs with magnetic resonance images. Methods This retrospective cohort study involved 2 groups of participants: 27 Tai Chi practitioners with more than 4 years of experience with regular Tai Chi exercise and 24 sex- and age-matched participants without Tai Chi experience. The lumbar magnetic resonance images of all participants were collected. The numbers of degenerated lumbar vertebrae and lumbar discs were evaluated by the same radiologist, who was blind to the grouping. Results The Tai Chi practitioners had significantly fewer degenerated lumbar vertebrae (1.9) and lumbar discs (2.3) than the control group (2.6 and 2.9, respectively). The most severely affected lumbar vertebrae and discs were L5 and L4/L5, respectively. Conclusion Regular performance of the simplified Tai Chi 24 form could possibly retard the degeneration of lumbar vertebrae and lumbar discs in middle-aged and aged people.

Eficacia de la auriculoterapia en pacientes con sacrolumbalgia aguda / Effectiveness of auriculotherapy in patients with acute low back pain

Se realizó un estudio quasiexperimental de 100 pacientes con sacrolumbalgia aguda, quienes acudieron a la Consulta de Ortopedia y fueron remitidos al Servicio de Medicina Natural y Tradicional del Policlínico del MININT de Santiago de Cuba, desde enero del 2015 hasta igual mes del 2016, con vistas a evaluar la eficacia de la auriculoterapia. Se conformaron 2 grupos (A y B) de 50 integrantes cada uno: los primeros recibieron tratamiento con auriculoterapia y los segundos, farmacológico. La mayoría de los afectados del grupo A mejoraron en menor tiempo y tuvieron menos reacciones adversas que los del B, lo cual demostró la eficacia de este tratamiento en el alivio del dolor lumbar(AU)

A quasi-experiment study of 100 patients with acute low back pain who went to the Orthopedics Service and were referred to the Natural and Traditional Medicine Service of the MININT Polyclinic in Santiago de Cuba, was carried out from January, 2015 to the same month in 2016, aimed at evaluating the effectiveness of auriculotherapy. Two groups were conformed (A and B) of 50 members each: the first ones received treatment with auriculotherapy and the second, pharmacological treatment. Most of those affected in the group A improved in less time and had less adverse effects than those of the group B, which demonstrated the effectiveness of this treatment in the relief of the lumbar pain(AU)

Electrophysiological mapping of rat sensorimotor lumbosacral spinal networks after complete paralysis.

Stimulation of the spinal cord has been shown to have great potential for improving function after motor deficits caused by injury or pathological conditions. Using a wide range of animal models, many studies have shown that stimulation applied to the neural networks intrinsic to the spinal cord can result in a dramatic improvement of motor ability, even allowing an animal to step and stand after a complete spinal cord transection. Clinical use of this technology, however, has been slow to develop due to the invasive nature of the implantation procedures and the difficulty of ascertaining specific sites of stimulation that would provide optimal amelioration of the motor deficits. Moreover, the development of tools available to control precise stimulation chronically via biocompatible electrodes has been limited. In this chapter, we outline the use of a multisite electrode array in the spinal rat model to identify and stimulate specific sites of the spinal cord to produce discrete motor behaviors in spinal rats. The results demonstrate that spinal rats can stand and step when the spinal cord is stimulated tonically via electrodes located at specific sites on the spinal cord. The quality of stepping and standing was dependent on the location of the electrodes on the spinal cord, the specific stimulation parameters, and the orientation of the cathode and anode. The spinal motor evoked potentials in selected muscles during standing and stepping are shown to be critical tools to study selective activation of interneuronal circuits via responses of varying latencies. The present results provide further evidence that the assessment of functional networks in the background of behaviorally relevant functional states is likely to be a physiological tool of considerable importance in developing strategies to facilitate recovery of motor function after a number of neuromotor disorders.

Unexpected lumbar abscess due to scarification wet cupping: a case report.

OBJECTIVE: This case presents a rare cause of lumbar abscess. METHODS: A 51-year-old male patient was admitted to the emergency department with a complaint of lumbar pain. Spinal magnetic resonance imaging revealed a lumbar abscess. RESULTS: The abscess was treated with drainage of the abscess and antibiotic. CONCLUSION: Scarification wet cupping therapy should be taken into consideration as a rare cause of lumbar abscesses in patients who present with skin findings indicative of scarification. Scarification wet cupping therapy practitioners must pay attention to hygienic measures.

[Structural changes in the sensory ganglia of the spinal nerves after repeated magnetic stimulation on the model of ischemic myelopathy].

The aim of this study was to examine the association of morphological changes in the-sensory ganglia of the spinal nerves (SGSN) with the cilinical symptomatology in rats with the experimentally induced ischemic myelopathy (IM), untreated or treated with repeated magnetic stimulation (RMS). The efficacy and mechanisms of RMS action on SGSN were studied by electron microscopy in 16 rats with IM. According to the results of treatment, in SGSN both at a distance from the damaged area (lumbar SGSN) and close to it (cervical SGSN) the morphological signs of regenerative-reparative processes were found in the cells and nerve fibers (restoration of the organelle structure in the cytoplasm o0f neurons and neurolemmocytes, the increase in the number of he latter and fiber remyelination). The expression of the structural changes correlated with the degree of functional recovery.

The immediate effects of sigmoid colon manipulation on pressure pain thresholds in the lumbar spine.

Visceral manual therapy is increasingly used by UK osteopaths and manual therapists, but there is a paucity of research investigating its underlying mechanisms, and in particular in relation to hypoalgesia. The aim of this study was to investigate the immediate effects of osteopathic visceral mobilisation on pressure pain thresholds. A single-blinded, randomised, within subjects, repeated measures design was conducted on 15 asymptomatic subjects. Pressure pain thresholds were measured at the L1 paraspinal musculature and 1st dorsal interossei before and after osteopathic visceral mobilisation of the sigmoid colon. The results demonstrated a statistically significant improvement in pressure pain thresholds immediately after the intervention (P<0.001). This effect was not observed to be systemic, affecting only the L1 paraspinal musculature. This novel study provides new experimental evidence that visceral manual therapy can produce immediate hypoalgesia in somatic structures segmentally related to the organ being mobilised, in asymptomatic subjects.

[Clinical observation of post-extension pulling massage in treating lumbar disc herniation].

OBJECTIVE: To observe the clinical effect of post-extension pulling massage in treating lumbar disc herniation. METHODS: From January 2008 to December 2008, 61 patients with lumbar disc herniation, 34 males and 27 females, ranging in age from 17 to 67 years with an average of 42.6 years, were treated with post-extension pulling massage after continued traction for 30 minutes (on alternate days one time, 3 times as a course of treatment). There was bulging type in 9 cases, hernia type in 22, free type in 30. After a course of treatment, the clinical effects were evaluated according to standard of Macnab, the items included pain, lumbar activity, normal work and life of patients. RESULTS: All patients were followed up from 1 to 9 months with an average of 4.6 months. After treatment, the symptoms and signs of patients had obviously improved in above aspects. According to standard of Macnab, 48 cases got excellent result, 10 good, 2 fair, 1 poor. CONCLUSION: The post-extension pulling massage in treating lumbar disc herniation can obtain satisfactory results, which have localized site of action, small compression for vertebral body and can reduce accidental injury.

Maintenance and improvement of interobserver reliability of osteopathic palpatory tests over a 4-month period.

CONTEXT: Few studies have shown that diagnostic palpation is reliable. No studies have shown that the reliability of diagnostic palpatory skills can be maintained and improved over time. OBJECTIVE: To investigate whether the reliability of selected palpatory tests used to identify lumbar somatic dysfunction was maintained during a 4-month period as part of a clinical observational study. METHODS: Participants with low back pain and participants without low back pain, recruited from a rural Midwestern community, were examined during 6 separate sessions over a 4-month period. During each data collection session, two blinded examiners, who had previously completed comprehensive consensus training, evaluated the lumbar region with four tests: static segmental positional asymmetry of the transverse processes in the horizontal plane, tissue texture abnormalities, resistance to anterior springing on the spinous processes, and tenderness induced by pressure on the spinous processes. Detailed protocols for each test were defined during a previous comprehensive consensus training period and were not revised during the current study. To verify that established interobserver reliability was maintained throughout the clinical study, quality control sampling was performed on all data. When findings were inconsistent between the two examiners, focused consensus training was performed as a means of recalibration to understand why assessments were inconsistent. Interobserver reliability for determining the presence or absence of somatic dysfunction was assessed using kappa coefficients. RESULTS: The study enrolled 64 participants, and 14 to 33 participants were examined per session. All four tests had acceptable interobserver reliability by the final data collection session. The test for static segmental positional asymmetry of the transverse processes in the horizontal plane had moderate to substantial reliability in all 6 sessions. The test for tissue texture abnormalities had moderate reliability in 5 of the 6 sessions. The test for resistance to anterior springing on the spinous processes had moderate reliability for 3 of the 6 sessions. The test for tenderness had substantial to almost perfect reliability for all 6 sessions. In general, interobserver reliability improved over time. CONCLUSIONS: Examiners were able to maintain and improve interobserver reliability of four lumbar diagnostic palpatory tests over a 4-month period.

The pelvic crossed syndromes: a reflection of imbalanced function in the myofascial envelope; a further exploration of Janda's work.

Structurally, the sacrum-coccyx provides the dual roles of serving as the base of the spinal column while also forming part of the pelvic ring. Physiological movement control of the pelvis and the spine are functionally interdependent. In particular, intra-pelvic control, (that between the ilia and sacrum/coccyx in support and control of the forces and small movements within the pelvic ring) is fundamental to controlling its spatial organization as a whole and its control on the femoral heads, all of which directly influence spinal alignment and control mechanisms. This involves coordinated activity in the related neuro-myofascial systems in providing mechanisms of both intrinsic and extrinsic support and control.

[Effect of electroacupuncture on expression of ionotropic glutamate receptor subunits and their genes in lumbar segments of spinal cord in rats with neuropathic pain].

OBJECTIVE: To observe the effect of electroacupuncture (EA) on the expression of ionotropic glutamate receptor (iGluR) subunits and their mRNAs in the lumbar segments of spinal cord in rats with neuropathic pain, so as to explore its underlying mechanism in relieving spinal hyperalgesia. METHODS: Thirty SD rats were randomly divided into control, model, and EA groups, with 10 rats in each. The spared nerve injury (SNI) model was established by ligature of the sural nerve after cutting off the common peroneal nerve and anterior tibial nerve. EA (2 Hz, 1 mA) was applied to "Huantiao" (GB 30) and "Weizhong" (BL 40) for 30 min, once daily for 7 days. Mechanical pain threshold was detected before and after modeling and before and after EA treatment. The expression levels of N-methyl-d-aspartic acid (NMDA) receptor subunits NR1 and NR 2 B,and AMPA receptor subunit GluR 1 of iGluR and their genes were assayed by Western blot and reverse transcription polymerase chain reaction (RT-PCR) separately. RESULTS: In comparison with control group, the mechanical pain thresholds were decreased significantly on day 2, 7 and day 14 following modeling in the model group (P < 0.05, P < 0.01). While compared with the model group, the pain threshold was increased considerably on day 14 in the EA group (P < 0.01). Compared with the control group, the expression levels of lumbar spinal cord NR 2 B and NR 2 B mRNA in the model group were increased significantly (P < 0.05), and those of lumbar spinal cord NR 1 and NR 1 mRNA, GluR 1 and GluR 1 mRNA in the model group increased slightly (P > 0.05). In comparison with the model group, the expression levels of lumbar spinal cord NR 2 B and NR 2 B mRNA in the EA group were downregulated remarkably (P < 0.05), and those of lumbar spinal cord NR 1 and NR 1 mRNA, GluR 1 and GluR 1 mRNA in the EA group down-regulated slightly (P > 0.05). CONCLUSION: EA can significantly suppress pain reaction in rats with neuropathic pain probably through down-regulating the expression of lumbar spinal cord NR 2 B protein and NR 2 B mRNA.

Acute and late effects on induction of allodynia by acromelic acid, a mushroom poison related structurally to kainic acid.

1. Ingestion of a poisonous mushroom Clitocybe acromelalga is known to cause severe tactile pain (allodynia) in the extremities for a month and acromelic acid (ACRO), a kainate analogue isolated from the mushroom, produces selective damage of interneurons of the rat lower spinal cord when injected either systemically or intrathecally. Since ACRO has two isomers, ACRO-A and ACRO-B, here we examined their acute and late effects on induction of allodynia. 2. Intrathecal administration of ACRO-A and ACRO-B provoked marked allodynia by the first stimulus 5 min after injection, which lasted over the 50-min experimental period. Dose-dependency of the acute effect of ACRO-A on induction of allodynia showed a bell-shaped pattern from 50 ag x kg(-1) to 0.5 pg x kg(-1) and the maximum effect was observed at 50 fg x kg(-1). On the other hand, ACRO-B induced allodynia in a dose-dependent manner from 50 pg x kg(-1) to 50 ng x kg(-1). 3. N-methyl-d-aspartate (NMDA) receptor antagonists and Joro spider toxin, a Ca(2+)-permeable AMPA receptor antagonist, inhibited the allodynia induced by ACRO-A, but not by ACRO-B. However, other AMPA/kainate antagonists did not affect the allodynia induced by ACRO. 4. Whereas no neuronal damage was observed in the spinal cord in ACRO-A-treated mice, induction of allodynia by ACRO-A (50 fg x kg(-1)) and ACRO-B (50 ng x kg(-1)) was selectively lost 1 week after i.t. injection of a sublethal dose of ACRO-A (50 ng x kg(-1)) or ACRO-B (250 ng x kg(-1)). Higher doses of ACRO-A, however, could evoke allodynia dose-dependently from 50 pg x kg(-1) to 500 ng x kg(-1) in the ACRO-A-treated mice. The allodynia induced by ACRO-A (500 ng x kg(-1)) was not inhibited by Joro spider toxin or NMDA receptor antagonists. These properties of the late allodynia induced by ACRO-A were quite similar to those of the acute allodynia induced by ACRO-B. 5. ACRO-A could increase [Ca(2+)](i) in the deeper laminae, rather than in the superficial laminae, of the spinal cord. This increase was not blocked by the AMPA-preferring antagonist GYKI52466 and Joro spider toxin. 6. Taken together, these results demonstrate the stereospecificity of ACRO for the induction of allodynia and suggest the presence of a receptor specific to ACRO.

Biomechanics of back pain.

This paper offers a mechanistic account of back pain which attempts to incorporate all of the most important recent advances in spinal research. Anatomical and pain-provocation studies show that severe and chronic back pain most often originates in the lumbar intervertebral discs, the apophyseal joints, and the sacroiliac joints. Psychosocial factors influence many aspects of back pain behaviour but they are not important determinants of who will experience back pain in the first place. Back pain is closely (but not invariably) associated with structural pathology such as intervertebral disc prolapse and endplate fractures, although age-related biochemical changes such as those revealed by a 'dark disc' on MRI have little clinical relevance. All features of structural pathology (including disc prolapse) can be re-created in cadaveric specimens by severe or repetitive mechanical loading, with a combination of bending and compression being particularly harmful to the spine. Structural disruption alters the mechanical environment of disc cells in a manner that leads to cell-mediated degenerative changes, and animal experiments confirm that surgical disruption of a disc is followed by widespread disc degeneration. Some people are more vulnerable to spinal degeneration than others, largely because of their genetic inheritance. Age-related biochemical changes and loading history can also affect tissue vulnerability. Finally the concept of 'functional pathology' is introduced, according to which, back pain can arise because postural habits generate painful stress concentrations within innervated tissues, even though the stresses are not high enough to cause physical disruption.

The passive straight leg raising test in the diagnosis and treatment of lumbar disc herniation: a survey of United kingdom osteopathic opinion and clinical practice.

STUDY DESIGN: Postal questionnaire survey. OBJECTIVES: To carry out a confidential postal survey of United Kingdom osteopaths in order to record and assess their use of the passive straight leg raising test in the diagnosis of, and choice of, manipulation for lumbar disc herniation. The study also sought to determine whether an association existed between osteopaths' manipulation of suspected lumbar disc herniation and their use of the straight leg raising test, the length of their working hours, and their use of manipulation for the treatment of other lumbar conditions. SUMMARY OF BACKGROUND DATA: The literature is not agreed on important aspects of the straight leg raising test, or on the use of spinal manipulation for suspected lumbar disc herniation. This is thought to be the first study to investigate opinion and practice in a large group of spinal manipulators, in this case United Kingdom osteopaths. METHODS: A questionnaire was sent to all 1030 United Kingdom osteopaths registered with the General Osteopathic Council in January 2000. It comprised four sections: personal characteristics, professional characteristics, background to low back pain cases, details of straight leg raising test understanding and use within the diagnosis and treatment of lumbar disc herniation. RESULTS: A response rate of 44% was achieved. United Kingdom osteopaths' opinions of low back pain and lumbar disc herniation clinical presentations, details of straight leg raising test mode of action, procedure, and interpretation were in keeping with the literature. Fifty-four percent of respondents sometimes employed manipulation in the treatment of lumbar disc herniation, but most of the others described the practice as "dangerous." The literature is similarly divided on the practice. Chi-square and Cramer V analysis implied that respondents were not influenced in choosing manipulation for lumbar disc herniation by their use of the straight leg raising test (chi2 = 4.002, df = 3, Cramer V = 0.0959, P = 0.261, alpha 0.05, n = 435). A moderate association implied that the frequency of use of such manipulation for all lumbar conditions influenced the choice of that treatment for lumbar disc herniation (chi2 = 81.808, df = 4, Cramer V = 0.4302, P < 0.001, alpha = 0.05, n = 442). There was also a weak association suggesting that hours worked per week influenced the choice of manipulation for lumbar disc herniation (chi2 = 9.840, df = 3, Cramer V = 0.1499, P = 0.020, alpha = 0.05, n = 438). CONCLUSIONS: Respondents to this survey frequently treated low back pain and often employed the straight leg raising test in its diagnosis. Their recognition of the clinical presentation of lumbar disc herniation and their use and understanding of the straight leg raising test were in keeping with the literature. Respondents were divided nearly equally between those who would expect patient benefit from the use of manipulation for lumbar disc herniation and those who criticized the practice. There is a need for further research into the clinical reasoning employed for the manipulative treatment of lumbar disc herniation.

Chiropractic management of a patient with myasthenia gravis and vertebral subluxations.

OBJECTIVE: The chiropractic management of a patient with myasthenia gravis and vertebral subluxation is described. We discuss the pathophysiology, clinical features, and treatment of patients with these diseases. CLINICAL FEATURES: The 63-year-old male patient suffered from complaints associated with the disease myasthenia gravis along with signs of vertebral subluxation. The patient had an initial complaint of dysphagia. In addition, the patient experienced swelling of the tongue, nausea, digestive problems, weakness in the eye muscles, difficulty breathing, myopia, diplopia, and headaches. Balance and coordination problems resulted in walking difficulties. INTERVENTION AND OUTCOME: Contact specific, high-velocity, low-amplitude adjustments were applied to sites of patient subluxation. Myasthenia gravis is no longer debilitating to the patient; he is medication free and has resumed a "normal life." CONCLUSION: The clinical aspects of the disease, including the possible role of chiropractic intervention in the treatment of patients suffering from myasthenia gravis, are also discussed. This case study encourages further investigation into the holistic approach to patient management by chiropractors vis-a-vis specific adjustments of vertebral subluxation.

Estimulaçäo elétrica da medula espinal para o tratamento da dor crônica: resultados / Eletrical stimulation of spinal cord for the treatment of chronic pain

Os resultados do tratamento de 50 doentes através do método da neuroestimulaçao da medula espinal sao apresentados. A dor foi decorrente de lesao traumática do cone medular e das raízes da cauda eqüina em 8 doentes, lesao da medula espinal em 14, neuropatia pós-herpética em 6, distrofia simpático-reflexa em 8, fibrose peridural em 6, doença oncológica em 1, avulsao das raizes do plexo braquial em 4 e decorrente da amputaçao de membros em 3 (dor em membro fantasma em 2 e no coto de amputaçao em 1). Os resultados foram considerados bons e excelentes, durante o período de seguimento, em 26 doentes (52 por cento). Vinte e quatro (48 por cento) nao se beneficiaram com a estimulaçao elétrica da medula espinal. Em 2 doentes o sistema implantado teve que ser removido devido a infecçao. Um dos doentes apresentou complicaçoes transitórias decorrentes de síndrome cordonal posterior. A estimulaçao elétríca da medula espinal nao contribuiu para o alívio da dor em 7 doentes com lesao traumática da medula espinal e raízes da cauda eqüina. Um doente teve excelente resultado após o implante; entretanto, observou-se recorrência da dor durante o acompanhamento clínico.Em 7 doentes com mielopatia, o resultado satisfatório obtido com o implante permaneceu durante o período de seguimento (mediana de 8,9 meses). Em doentes com nevralgia pós-herpética foram observados resultados bons e excelentes após o ato operatório; no entanto, foram observadas recorrência parcial da dor em l e recorrência total em outro. Dentre os 7 doentes com distrofia simpático-reflexa, a estimulaçao da medula espinal resultou no alívio imediato e persistente da sintomatologia em 6. Um doente apresentou recorrência da dor. A estimulaçao elétrica da medula espinal propiciou alívio imediato da dor em 2 doentes com avulsao das raizes do plexo braquial. Entretanto, a dor recorreu em 1.Um doente com dor no coto de amputaçao e 2 com dor no membro fantasma nao apresentaram alívio com estimulaçao elétrica da medula espinal. O doente com dor oncológica visceral apresentou resultado satisfatório durante os 2 últimos meses de vida.Baseado na análise deste trabalho, é possível concluir que a estimulaçao elétríca da medula espinal é especialmente recomendada para o tratamento das síndromes neuropáticas com lesao mínima ou parcial das estruturas nervosas, como as que ocorrem em casos de distrofia simpático-reflexa, radiculopatias ou lesao parcial da medula espinal.
