[Cave: interscalene catheters]. / Cave: Interskalenuskatheter.

Interscalene regional anesthesia is an established and highly effective procedure; however, it represents an increased level of risk due to the close proximity of anatomical structures, such as the cervical spinal cord and many vessels. Furthermore, due to inadvertent placement of a catheter close to the cervical spinal cord or into a vessel, as opposed to a single shot injection technique, it remains a latent danger until it is removed. This article describes seven  cases of misplaced catheters. The etiology and symptoms are discussed as well as recommendations regarding the prevention of catastrophic complications. As a result, internal practice guidelines are recommended for anesthesia departments in order to enhance the safety and quality of regional anesthesia.

[Outpatient anesthesia for patients with obstructive sleep apnea: results of a national survey]. / Ambulante Anästhesie bei Patienten mit obstruktivem Schlafapnoesyndrom: Ergebnisse einer deutschlandweiten Umfrage.

BACKGROUND: In Germany there is currently no national standard for the management of patients with obstructive sleep apnea syndrome (OSAS). The object of this survey was to obtain information on the treatment concept for patients with OSAS and to report on the current practice in Germany. METHODS: Data collection was obtained through an online questionnaire. A total of 12,113 members of the supporting anesthesia societies from all over Germany were invited to participate via e-mail. Additionally an announcement was made in a professional journal. RESULTS: A total of 1,671 questionnaires were analyzed. The average age of the respondents was 45 years, 64% were male and 36% were female. The average work experience was 16 years and 85% of the respondents were consultants. In total 85% of anesthesiologists were predominantly working in inpatient care and 12% were predominantly active in outpatient care. Of the respondents 63% preferred regional anesthesia, 20% preferred general anesthesia for patients with OSAS and 17% did not have a preference for a specific anesthesia procedure. Outpatient surgery for patients with OSAS was performed by 72% of the respondents using regional anesthesia and by 55% of the respondents using local anesthesia with sedation. Of the anesthesiologists 49% consented to outpatient surgery using general anesthesia and 14% to interventions involving the airways. Compared to anesthesiologists working predominantly in inpatient departments, those working predominantly in outpatient departments treated patients with OSAS more frequently on an outpatient basis, used general anesthesia significantly more often, discharged those patients significantly earlier and observed less complications. CONCLUSIONS: This survey shows that outpatient surgery for patients with sleep apnea is common practice in Germany. It is also performed when patients have moderate or severe OSAS and for respiratory tract surgery. This means that the management is not conform to the guidelines of the American Society of Anesthesiologists (ASA).

[Repeated percutaneous chemical sympathectomy as a therapeutic option for treating PAD II]. / Wiederholte perkutane chemische sympathektomie als therapieoption bei peripherer arterieller verschlusskrankheit II.

The value of percutaneous chemical lumbar sympathectomy (LSE) for the treatment of peripheral arterial disease (PAD) is still being discussed controversially. In particular, a benefit for Fontaine stage II PAD could not yet be shown. This case report is about a patient suffering from Fontaine stage II PAD. By applying five LSE in regular intervals good symptom control could be achieved and maintained for more than 5 years. The case is an occasion to call for larger controlled studies designed to find out the efficacy of LSE for the treatment of stage II PAD. Mechanisms and available data are discussed.

[Implementation of a standardized perioperative pain management concept in three hospitals of a consortium]. / Implementierung eines standardisierten perioperativen Schmerzmanagementkonzepts in drei Krankenhäusern eines Klinikverbundes.

BACKGROUND: Provision of sufficient perioperative pain therapy is an obligation in the clinical management of patients suffering from pain. The implementation of a standardized pain management concept was planned to be introduced in the clinical routine. The results of three hospitals are shown. MATERIAL AND METHODS: The concept included tools which gave information about legal aspects and basic fundamentals of pain relief, management modules regarding agreements on the implementation of perioperative pain therapy, instruments to measure pain intensity, assigning accountability and documentation modules. Questionnaires were carried out according to Picker. RESULTS: The project revealed that, according to the Picker questionnaire, about 50% of the patients treated in the hospitals had pain, 30-40% still had intensive pain during the stay in hospital and 90% of the patients received pain relief medication within 10 min of the request. More than 78% of the patients thought the hospital staff did their best to relieve the pain and over 92% found the pain treatment adequate. CONCLUSION: It was possible to implement a standardized perioperative pain therapy concept in three hospitals of a consortium. Whether an adequate pain relief can be improved with the help of standard measurements and documentation, could not be evaluated in this study.

[New pathways in undergraduate medical education - first experiences with the cross section speciality emergency and intensive care medicine]. / Neue Wege der studentischen Lehre - Erste Erfahrungen im Querschnittsbereich Notfall- und Intensivmedizin.

OBJECTIVE: On October 1 (st) 2003 Emergency Medicine was recognised for the first time as an independent cross section speciality in the new German "Approbationsordnung fuer Aerzte" (Medical Licensing Regulations). These amendments were made not only to increase the amount of small group teaching sessions but also to encourage a multidisciplinary and rather practical approach to the related topics. This article portrays the realisation of these objectives in form of a multidisciplinary module, as it has been established at University of Göttingen Medical School since the summer semester of 2004. We present the new curriculum, calculate the associated personnel resources and demonstrate the results of the structured evaluation given by the participating students. METHODS: We linked the fields of emergency and intensive care medicine by splitting them up into submodules which the students had to run through according to a set rota. 162 students were allocated to 27 small groups. Every student received a total of 38.5 hours of teaching, with the workshops coming to 46.8 %. The workshops comprised of nine sessions, three in Emergency Medicine, four in Intensive Care Medicine and two at human patient simulators. In addition we scheduled a seminar and an accompanying lecture. The final examination was performed as an Objective Structured Clinical Evaluation (OSCE). RESULTS: The realisation of the new module required a total of 1290 working hours for medical staff and 130 for our student aids. Compared to all other modules of Goettingen University Medical School the module here presented obtained the highest overall evaluation score by the medical students. Lessons with a high amount of practical involvement (i. e. Emergency Medicine and simulator-based workshops) were significantly better evaluated than rather formal teaching techniques, such as the lectures and the seminar. According to the students' self-assessment the simulator-based workshops were seen particularly valuable for the facilitation of knowledge transfer into clinical practice. CONCLUSION: The determined realisation of the new German Medical Licensing Regulations requires considerable time resources. However, its evaluation by the medical students is strikingly positive.

Do intracellular, extracellular or urinary magnesium concentrations predict renal retention of magnesium in critically ill patients?

BACKGROUND AND OBJECTIVE: Magnesium disorders are common in hospitalized patients. In patients with low or normal magnesium, the intravenous magnesium loading test has been demonstrated to be a sensitive test to assess magnesium deficiency in critically ill patients. However, it is more time consuming and more difficult than the measurement of intracellular or extracellular magnesium concentrations. This study evaluated whether erythrocyte, plasma and urinary magnesium concentrations predict renal magnesium retention measured by th magnesium loading test. METHODS: One-hundred-and-three intensive care patients (36 females, 67 males) in a tertiary care centre and 41 healthy subjects (13 females, 28 males) took part in this prospective study. Intracellular, total plasma, ionize extracellular and urinary magnesium concentrations were measured and also magnesium retention by intravenous magnesium loading test. RESULTS: Total plasma magnesium concentration was poorly correlated with magnesium retention (r = 0.36 r2 = 0.13) and was the only parameter that significantly predicted magnesium retention in intensive care patients (P < 0.01). However, only 10% of the magnesium retention data were linked to the total plasma magnesium concentration. CONCLUSIONS: Total plasma magnesium concentration predicts magnesium retention in critically ill intensive care patients but not intracellular and urinary magnesium concentrations. Only a small proportion of the magnesium retention was due to the total plasma magnesium concentration.

Outcome prediction in critical care: physicians' prognoses vs. scoring systems.

BACKGROUND AND OBJECTIVE: To compare the accuracy of prognoses made by intensive care physicians with the performance of two indicators, the original Simplified Acute Physiology Score (SAPS) II and a modified version optimized to the patient sample. METHODS: Data from 412 patients consecutively admitted to intensive care units of Göttingen University Hospital, Germany, were collected according to the original score criteria. Information necessary for the computation of SAPS II and the vital status on hospital discharge was recorded. To customize the original SAPS II in our cohort, the database was randomly divided into two subgroups. Logistic regression analysis with physiological values as explanatory variables was used. A bootstrap procedure completed the process. Furthermore, physicians were asked to indicate their prognostic judgement concerning the patients' hospital mortality. RESULTS: Discrimination analysis showed the following areas under receiver operating characteristic curves: physicians' prognoses 0.84 (confidence interval (CI): 0.79-89), SAPS II 0.75 (CI: 0.69-0.80) and customized SAPS 0.72 (CI: 0.66-0.78). The physician's forecast was significantly better, while the customized and the original SAPS were not substantially different as regards their accuracy. CONCLUSIONS: Prognoses made by physicians are superior to objective models. This may result from more extensive knowledge and other kinds of information available to clinicians. A clinician's action also depends on his/her prognosis at the beginning of the treatment, giving raise to a possible correlation between medical outcome and the clinician's prognosis. Our findings indicate that physicians do not limit their prognosis to the objective factors at their disposal, but indicate that they base their decisions on experience and individual observations.

[Evaluation of the disability of ventilated patients]. / Untersuchung zur Befindlichkeit von beatmeten Patienten.

OBJECTIVE: It is very important to investigate the patient's disability and pain. Interviews of intubated and tracheotomised patients were neglected because of inadaequate measuring methods. This is the first prospective study that evaluates the disability and pain of intubated and tracheotomised patients. METHODS: Disability, Hospital Anxiety and Depression Scale, Visuelle Analogue Scale, Glasgow Coma Scale and structured questions were used to investigate the disability and pain of ventilated patients. 26 patients of an interdisciplinary operative intensive care unit took part in the study. Sociodemographic parameters, ventilation, sedation and pain were evaluated. Doctors and nurses were asked to assess the patient's pain and disability. RESULTS: 17 intubated and 9 tracheotomised patients were included in the study. Mean intensity of pain was 30.3 (SD = 31.4), anxiety 40.8 (SD = 31.4), disability 30.0 (SD = 11.5) and disability caused by ventilation 61.9 (SD = 28.5). 46.2 % of the patients had a pathological subscale of anxiety and 50 % of depression in the Hospital Anxiety and Depression Scale. Nurses assessed the patient's disability and pain better than the doctors. CONCLUSION: A high disability has to be taken in account in the therapy of intubated and tracheotomised patients.

Clinical and morphological aspects of death due to liquid nitrogen.

A 24-year-old student died while filling flasks with liquid nitrogen. The arms, legs and back were frozen and the face, ears and neck showed a dark red and livid colour with horizontal lines of demarcation. In the electrocardiogram, the heart showed asystolia followed by wide ventricular complexes. The patient was intubated orally as the situs of the larynx and pharynx showed no pathology findings. Cardiopulmonary resuscitation was carried out and terminated after 90 min. Unfortunately, the body temperature was not measured. The gas analysis of venous blood showed metabolic acidosis and oxygen deficiency. The student had worked alone with nitrogen, without opening the windows and without a working ventilation system. While filling the third flask he lost consciousness. As nitrogen does not cause characteristic prodromal signs he laid on the floor and was unable to help himself. The liquid nitrogen which was still escaping spread over the floor and vaporized. The student died from asphyxia due to oxygen deficiency in an atmosphere of nitrogen.

Effectiveness of a multimodal treatment program for chronic low-back pain.

In recent years, multidisciplinary pain programs were seen to successfully treat patients by basing treatment on a combination of physical exercise and psychological interventions. However, in spite of their effectiveness, it still remains to be clarified exactly which features of these programs were responsible for patient improvement. Cognitive-behavioral models posit that improvement is due, in part, to changes in patient coping strategies. Nonetheless, as reflected by the conflicting opinions present in the literature, it is questionable whether a so-called 'cognitive shift' is an accurate indicator for return to work of disabled patients. Ninety patients with chronic low back pain took part in a multidisciplinary treatment program. Therapeutic environment reinforces wellness behavior and enhances the patients' sense of control over their pain and resulting disability. The main therapeutic target point was to facilitate return to work. Ways of coping were measured by a well studied coping inventory in the German language (FEKB). Factor analysis revealed three factors: 'catastrophizing', 'search for information' and 'cognitive control'. In addition, assessment included measurements of pain intensity, depression, disability, flexibility of the lumbar spine, and different performance parameters. All of them were measured prior to and at the end of treatment, and following intervals of 6 and 12 months after discharge from program. Measurements showed significant changes over time, but more importantly, nearly all results were seen to stabilize at the 6- and 12-month evaluation following treatment. The coping strategies demonstrated little or poor change. In addition, coping measures and change in coping behavior showed poor prognostic relevance. But other psycho-social parameters like self-evaluation of potential return-to-work, application for pension, the length of pre-absence from work, and a decrease in subjective disability following treatment were effective indicators for 'back-to-work'. Other objective parameters, such as medical history, physical impairment and general physical variables were seen to have little predictive value in determining a return to work. The results suggest that the primary target point for further investigation is the analysis of the patients' beliefs about their pain. Our results indicate that future research must be attentive to the complex interactions between environmental factors and the coping demands posed by the specific nature of pain problems.

[Exitus letalis caused by liquid nitrogen]. / Exitus letalis durch flüssigen Stickstoff.

A 24-year old student died from asphyxiation while filling flasks with liquid nitrogen. The upper and lower extremities and the back were frozen. The face, ears and neck were livid with a horizontal line of demarcation. A few wide ventricular complexes were seen in the initial ECG, followed by asystole. The patient's trachea was intubated, his lungs ventilated with 100% oxygen and CPR initiated. The site of larynx and pharynx were without pathological findings. 250 ml of a crystalloid solution were infused into the external jugular vein. It was not possible to measure the body temperature. Venous blood gas analysis showed a metabolic acidosis and hyperkaliaemia. CPR was terminated after 90 minutes. Own protection is most important for the rescue team if a nitrogen atmosphere is expected.

[Isokinetic strength of lumbar muscles in patients with chronic backache]. / Die isokinetische Kraftleistungsfähigkeit der Rumpfmuskulatur von Patienten mit chronischen Rückenschmerzen.

Lumbar isokinetic strength and the influence of age, bodyweight and testing velocity in patients with chronic low back pain in comparison with persons without pain. Lumbar isokinetic strength parameters of 80 patients with chronic low back pain and 70 persons without pain were compared and the influence of age, bodyweight and testing velocity was evaluated. The patients with chronic low back pain showed less strength than the persons without pain. All parameters of extension discriminated between the two groups whereas only some of the flexion parameters did. The isokinetic strength of the lumbal extension muscles was higher than the strength of the flexion muscles. In patients with chronic low back pain, isokinetic strength of lumbar extension muscles was more reduced than the strength of flexion muscles in comparison with persons without pain. At 90 degrees/sec in comparison to 60 degrees/sec, lower extension forces, higher flexion forces and changed ratios of flexion and extension muscles were measured. Age had an influence only on women. There were no changes in ratios of flexion and extension muscles with increasing age. Bodyweight showed weak correlations with isokinetic flexion forces. The influence of different factors on isokinetic force varies between patients with chronic low back patients and healthy subjects.

Prediction of success from a multidisciplinary treatment program for chronic low back pain.

STUDY DESIGN: The study included 90 disabled patients with chronic low back pain recruited from a pain clinic who were admitted to an 8-week program of functional restoration and behavioral support. Initial evaluations included a medical examination, rating of the physical impairment, a personal interview, a visual analogue scale to record pain intensity, an assessment of limitations for daily activities, a pain disability index, a depression and psychovegetative scale, and a scale to evaluate general living standards. The physical assessment included different flexibility measurements, measurement of power and endurance through standardized exercises, and measurements of isokinetic trunk and lifting strength and general endurance. The measurements were repeated at the end of the 8-week program and thereafter an intervals of 6 and 12 months. Final analyses were carried out on 82 patients. OBJECTIVES: To determine whether objective or subjective signs most influence the outcome of rehabilitation. SUMMARY OF BACKGROUND DATA: In recent years, several studies have shown that active and intensive multimodal treatment of chronic low back pain is successful. Until now there has been lack of information about which patients will respond to the therapy and what is the most effective part of treatment. METHODS: Prognostic factors (return to work, pain intensity, self-assessment of treatment success by patients) were tested by studying variance and regression analyses for their ability to predict treatment outcome. RESULTS: Certain factors were identified that had a significant impact on determining the probability of a patient's return to work and the reduction of pain intensity. These factors included self-evaluation for predicting a return to work, the length of absence from work, application for pension, and a decrease is disability after treatment. Overall satisfaction with treatment was best determined by the number of medical consultations before treatment, the extent of disability, previous measures taken for coping with the disease, and reduction of disability during treatment. Medical background, medical diagnosis, and physical impairment had no predictive value. Physical variables (i.e., mobility, strength, endurance, and physical performance) also demonstrated only limited predictive value. CONCLUSION: This study has demonstrated that the most important variable in determining a successful treatment of chronic low back pain is the reduction of subjective feelings of disability in patients.

[Multidisciplinary treatment program on chronic low back pain, part 4. Prognosis of treatment outcome and final conclusions]. / Das Göttinger Rücken Intensiv Programm (GRIP) Ein multimodales Behandlungsprogramm für Patienten mit chronischen Rückenschmerzen, Teil 4. Prognostik und Fazit.

PROBLEM: Studies using a multimodal approach in order to prognose therapeutic success in patients suffering from back pain were seen to have highly diverse results. However, in spite of various independent health care systems, a common interest prevails in identifying determinants of therapeutic success in order to improve therapy. METHODS: Ninety disabled patients with chronic low back pain were admitted to an 8-week out-patient program of functional restoration and behavioral support. The program consisted of a pre-program (education, stretching and calisthenic exercises 4 h a day, three times a week for 3 weeks) and an intensive treatment period (physical exercises, back school education, cognitive behavioral group therapy, relaxation training, occupational therapy, socioeconomic and vocational counseling) which took place for 5 weeks, 7 h a day as an outpatient program. The program's philosophy encourages active effort on the patients' part in order to improve their functional status within a therapeutic environment. This reinforces behavior conducive to getting well, enhances the patients' sense of self-control over their pain and the resulting disability. The main therapeutic target was to facilitate the patients' return to work. Apart from medical examination and personal interview, the patients' physical impairment, pain descriptions, and psychological distress were also measured. This included variables such as depression, psychovegetative complaints, quality of life and workplace satisfaction, disability, and coping with disease. Measurements were repeated at the end of the 8-week program, and following 6 and 12 month intervals. The reliability of prognostic factors in predicting treatment outcome (return to work, reduction of pain intensity, self-assessment of success by the patients) was tested by analyses of variance and discriminant function analyses. RESULTS: Patients' return to the workplace could be predicted in 85% of cases based on whether an application for pension had been made, on the length of duration of work disability, and on "fixed" assumptions on the part of the patient concerning his work situation. Pre-treatment somatic findings (for example, diagnosis, degree of physical impairment, and functional debilities), together with depressive and psychovegetative reactions, were shown to have no connection with the patient's ability to return to the workplace. Similar findings were demonstrated for the prediction of pain reduction and patient satisfaction with treatment. CONCLUSIONS: Predicting successful treatment is hardly possible without analyzing individual circumstances, focusing on sociodemographic variables, workplace-related conditions, and aspects of individual motivation. With regard to objective therapeutic success, subjective perceptions proved highly influential. Treatment proved successful only when the patient's perception of functional disability was minimized. Hence, individual perceptions and experiences were more important than physical capabilities.

[Multidisciplinary treatment program on chronic low back pain, part 3. Psychosocial aspects]. / Das Göttinger Rücken Intensiv Programm (GRIP)--ein multimodales Behandlungsprogramm für Patienten mit chronischen Rückenschmerzen, Teil 3. Psychosoziale Aspekte.

PROBLEM: The majority of authors agree today that psychosocial factors have more influence on a successful treatment of chronic back pain than other variables, in particular medical findings. Therefore treatments aim to integrate psychotherapeutic intervention in order to lessen emotional impairment, to change behavioral patterns (which advocate rest and the avoidance of physical activity), and to change cognitive attitudes and fears concerning exercise and work ability. Nevertheless, the interplay of cognitive measures and disability in treatment programs still remains an unclear issue. METHODS: Ninety disabled patients with chronic low back pain were admitted to an 8-week outpatient program of functional restoration and behavioral support. The program consisted of a pre-program (education, stretching and calisthenic exercises) and an intensive treatment period (physical exercises, back school education, cognitive behavioral group therapy, relaxation training, occupational therapy, vocational counseling), which took place for 5 weeks, 7 h a day, as an outpatient program. The targets of the psychological interventions were (a) to change maladaptive behavior (inactivity, social withdrawal) and increase the patient's activity level at home, (b) to alter maladaptive cognitions (somatization, catastrophizing, passive expectations concerning treatment) and to improve their own positive coping skills, (c) to identify and stop operant conditioned behavior, and (d) to prevent depressive symptoms and strengthen the level of emotional control. The program's philosophy encouraged the patients' active efforts to improve their functional status within a therapeutic environment that reinforced positive behavior traits conductive to getting well. The main therapeutic target was to facilitate a return to work. Apart from a medical examination and a personal interview, the patients' physical impairment, pain descriptions, and psychological distress (according to different criteria for evaluation) were also measured. This included variables such as depression, psychovegetative complaints, quality of life and workplace satisfaction, disability, and coping with disease. Measurements were repeated at the end of the 8-week program, and following 6- and 12-month intervals. RESULTS: In comparison with the initial values, a statistically significant improvement became evident in reducing pain, disability, depression, and psychovegetative signs (P < 0.001). Nearly all results remained stable at the 6- and 12-months examinations. Apart from these results, coping measurements demonstrated little improvement in the three factorial coping dimensions. By use of regression analyses, a differentiated description of psychosocial connections became apparent in three different ways of coping (catastrophizing, searching for information, cognitive control) and parameters of disability. Disability levels corresponded poorly with pain descriptions, physical impairment and coping dimensions. This result indicates that disability should be viewed as a separate component in assessing the patients' description of low back pain. CONCLUSION: An analysis of coping dimensions demonstrated that current cognitive measures might be too general to explain low back disability adequately. In addition, the results indicate that the use of the 'catastrophizing' factor as a separate variable is questionable, since it may simply be a symptom of depression. The relevance of coping as a sensitive parameter for change is also addressed. It is suggested that an alteration in coping strategies may be an important treatment effect, but is subject to individual prerequisites to maximize treatment response. Thus, future research must focus on the complex interactions between personality variables, environmental factors, and the coping demands posed by the specific nature of pain problems. A more lengthy evaluation of so-called 'fear-avoidance beliefs' in combination with 'disability' and coping dimensions could possibly lead to further treatment on the development of chronicity in chronic low back pain patients.

[Multidisciplinary treatment program for chronic low back pain, part 2. Somatic aspects]. / Das Göttinger Rücken Intensiv Programm (GRIP)--ein multimodales Behandlungsprogramm für Patienten mit chronischen Rückenschmerzen, Teil 2 Somatische Aspekte.

PROBLEM: There is a great need to expand current knowledge of the various functional capacity measurements used in the rehabilitation of chronic low back pain (CLBP) patients. The literature on these patients reports that mobility, endurance, trunk strength and lifting capacity decrease during the process of chronicity. Chronically disabled patients appear to have lower functional capacity than asymptomatic persons. METHODS: Our study group consisted of 90 disabled CLBP patients (44 female, 46 male; average age 42 years) who underwent a multidisciplinary 8-week daily treatment program of functional restoration with behavioral support (instruction, endurance training, strength exercises, behavioral and treatment to facilitate return to work therapy). Initially these patients where compared with 107 asymptomatic persons (44 female, 63 male, average age 41 years). The patients were investigated before and after treatment, and at intervals of 6 and 12 months. The reliability of the functional measurements was evaluated by interrater comparison. Physical assessment included a medical examination (mainly diagnosis of radicular or nonradicular pain), changes in the lumbar spine revealed by X-ray studies according to Herron and Turner, rating of physical impairment according to Waddell, flexibility, length of hamstrings muscles (SLR), test of power and endurance of trunk movement by standardized exercises according to the Swiss group of Spring and isokinetic measurements (LIDO Back), tests of lifting capacity (LIDO Lift), and (in part) of general endurance on a cycle ergometer (CASE 15 Marquette). RESULTS: Physical findings showed that mobility was reduced substantially in patients suffering from back pain due to reduced SLR (shortened hamstrings) and decreased spinal mobility. Patients also demonstrated significant reductions in their ability to perform lifting tasks in comparison to healthy individuals. The results of trunk flexion showed no significant differences between patients and the control group, whereas the ability to perform trunk extension was much better in the control group. In principle we found the same results with isokinetic measurements as in the exercises without machines. Cardiovascular endurance was also much better in the control group than it was in the back pain patients. At the end of the treatment program all physical deficits were improved significantly. In many cases performance was comparable with that of the control group. With time, however, training effects gradually decreased. The success of treatment (return to work, absence from work, pain reduction, use of medical care) was independent of the functional status of the patients before and after treatment. CONCLUSION: Study results showed that physical capacity in disabled patients with low back pain is substantially reduced in comparison to persons who do not suffer from back pain. The only exception was in trunk flexor strength and endurance, in which measurements did not differ between the patients and the control group. However, even CLBP- patients with long-term pain and severe physical illness can successfully improve their physical condition by participating in an active treatment program. Back extensor muscle training has to be included in physical therapy. Because of loss of condition during the time after treatment, regular monitoring of patients and their home training programs is necessary. Overall, treatment of CLBP has to include physical training and psychosocial treatment to achieve satisfactory results.

[Multidisciplinary treatment program for chronic low back pain, part 1. Overview]. / Das Göttinger Rücken Intensiv Programm (GRIP)--ein multimodales Behandlungsprogramm für Patienten mit chronischen Rückenschmerzen, Teil 1 Ergebnisse im Uberblick.

UNLABELLED: A multimodal treatment program is presented in cases of functional restoration for chronic low back pain. The study comprises four parts. Part I gives an overview of the different results of the study. Part II focuses on the medical and functional examination in comparison with persons who do not suffer from back pain. Part III describes psychosocial aspects (depression, complaints, ways of coping, disability) and psychotherapy. In part IV prognostic factors and their reliability for predicting treatment outcome (return to work, pain intensity, self-assessment of success by patients) are examined. In addition the relevant effects of the program on social and health care systems are also addressed. PROBLEM: The incidence of low back pain is continuously increasing, causing tremendous costs for the health insurance system. Therefore effective treatment methods are needed that take into account somatic, psychological and social factors. Chronic low back pain is conceptualized as a complex phenomenon including biological, social and psychological aspects, all of which should be addressed in a treatment program. A multimodal treatment program for chronic low back pain is presented, in which physical activity and cooperation of the patient are the primary targets. Therapeutic aims focus less on pain reduction and emphasize instead pain control, individual responsibility of the patient, and early reintegration into the working environment. The specific goals of the program are to increase the physical abilities of the patients (i. e., flexibility, strength and endurance), to increase patients' knowledge and the use of body mechanics and back protection techniques, to decrease medication-intake, to decrease dependency on the medical community, to improve patients' own positive coping skills and levels of emotional control, to increase the patient's activity level at home and to facilitate a return to work. METHODS: A total of 90 disabled patients with chronic low back pain were admitted to an 8-week program of functional restoration and behavioral support. The program consisted of a pre-program (3 weeks: education, stretching and calisthenic exercises) and an intensive treatment period (aerobics, functional strength and endurance exercises, back exercises, cognitive behavioral group therapy, relaxation training, socioeconomic and vocational counseling) which took place for 5 weeks, 7 h a day, on an outpatient basis. Apart from a medical examination and a personal interview, the patients' physical impairment, pain descriptions, and psychological distress (according to different criteria for evaluation) were also measured. This includes variables such as depression, psychovegetative complaints, quality of life and workplace satisfaction, disability, and coping with disease. Measurements were repeated at the end of the 8-week program, and after 6 and 12 months. RESULTS: In total 84 patients (94 %) were examined following treatment. There was a statistically significant improvement in flexibility, strength, lifting capacity, and endurance measurements ( p < 0.001) at the end of the treatment. In addition, significant reductions in pain, disability, depression, and psychovegetative signs were demonstrated ( p < 0.001). There was a decreased use of medical treatment for back pain following the program, with 42 % of the patients refraining from the intake of analgesics, followed by a significant reduction in physiotherapy and the consultation of physicians. Assessment of the patients' reported increased activity levels at home also supported findings that statistical improvements were significant. Sixty-three percent of the patients were found to have returned to active, productive work following discharge from the program. Most of the improvements remained stable at the 6- and 12-month follow-up examinations. CONCLUSION: The results demonstrate the effectiveness of the multimodal program of functional restoration, not only concerning positive changes in somatic, psychological and physical variables, but also with respect to the number of patients who returned to work. Our methods are also compared with the discrepant results of multimodal treatment in the United States and Scandinavia.

[Interrater studies of evaluating the reliability of somatic findings]. / Interrater-Untersuchungen zur Reliabilitätsprüfung somatischer Befunde.

20 patients (11 female, 9 male) without low back pain were included in two interrater studies carried out by three physical therapists. The following variables were investigated: shape of the spine, iliac crest heights, twisting of the pelvis, spine test, length of legs, Patrick sign, Schober test, fingertip-to-floor measurements, flexion and extension of the lumbar spine, straight-leg raising, and length of the iliopsoas and the rectus muscles. Intraclass coefficients for the ordinal variables, and kappa coefficients for the nominal variables were calculated for evaluation of interrater agreement. In both investigations, the Schober sign, lumbar flexion, fingertip-to-floor measurements, straight-leg raising of the left leg, and lengths of both legs were almost perfectly reliable. All other variables exhibited a lower reliability between the three therapists.

Lumbar range of motion: reliability and validity of the inclinometer technique in the clinical measurement of trunk flexibility.

STUDY DESIGN: This study examines the reliability and validity of measuring lumbar range of motion with an inclinometer. OBJECTIVES: To find out whether a manual determination of the reference points for measuring lumbar range of motion is as reliable as radiologic determination for positioning the inclinometers, lumbar range of motion was determined in degrees by evaluating radiographs and by using the inclinometer technique of Loebl. SUMMARY OF BACKGROUND DATA: Reliability and validity of the inclinometer technique as a clinical measurement of trunk flexibility were investigated. Fifty-four patients participated in the study. METHODS: Lumbar range of motion measurements were taken with and without radiologic control of the T12 and S1 vertebrae as reference points for positioning of the inclinometers. An interrater correlation was done of the inclinometer techniques of a physician and a physiotherapist. Functional radiographs were investigated in a standing position. Lumbar range of motion measurements based on radiographs and those taken using the inclinometer alone were correlated to validate the inclinometer technique. RESULTS: Lumbar range of motion measurements taken with and without radiologic determination showed a very close correlation (r = 0.93; P < 0.001). Flexion alone also demonstrated a close correlation (r = 0.95; P < 0.001), whereas extension showed a somewhat smaller correlation (r = 0.82; P < 0.001). Total lumbar range of motion (r = 0.94; P < 0.001) and flexion (r = 0.88; P < 0.001) were closely related, as indicated by the interrater correlation, whereas extension (r = 0.42; P < 0.05) showed a lesser correlation. Correlation of the measurements taken radiographically and by inclinometer demonstrated an almost linear correlation for measurements of the total lumbar range of motion (r = 0.97; P < 0.001) and flexion (r = 0.98; P < 0.001), whereas extension (r = 0.75; P < 0.001) did not correlate as well. CONCLUSIONS: The noninvasive inclinometer technique proved to be highly reliable and valid, but the measurement technique for extension needs further refinement.

Lumbar range of motion: influence of time of day and individual factors on measurements.

STUDY DESIGN: Influence of time of day and individual factors on the measurements of the lumbar range of motion was investigated. OBJECTIVES: To investigate factors that influence lumbar range of motion. SUMMARY OF BACKGROUND DATA: Twenty-nine patients with chronic low back pain participated in the study. METHODS: The lumbar range of motion was measured by inclinometer technique, Schober sign, modified-Schober sign, and fingertip-to-floor method in the morning, at noon, and in the afternoon. The lumbar range of motion was correlated with patients' gender, age, and body weight. RESULTS: Total lumbar range of motion measured by the inclinometer technique and the modified-Schober sign increased significantly throughout the day from morning to afternoon. Extension lumbar range of motion was shown to be independent of the time of measurement. There were no significant correlations between lumbar range of motion and gender, age, and body weight of the patients. CONCLUSION: For the reliability of a measurement, it is important to investigate lumbar range of motion at the same time of day.
