ABSTRACT

Introduction: Pain is a prominent complication in spinal cord injury (SCI). It can either occur as a direct or as an indirect consequence of SCI and it often heavily influences the quality of life of affected individuals. In SCI, nociceptive and neuropathic pain can equally emerge at the same time above or below the level of injury. Thus, classification and grading of pain is frequently difficult. Effective treatment of SCI-related pain in general and of neuropathic pain in particular is challenging. Current treatment options are sparse and their evidence is considered to be limited. Considering these aspects, a clinical practice guideline was developed as basis for an optimized, comprehensive and standardized pain management in SCI-related pain. Methods: The German-Speaking Medical Society for Spinal Cord Injury (Deutschsprachige Medizinische Gesellschaft für Paraplegiologie - DMGP) developed a clinical practice guideline that received consensus from seven further German-speaking medical societies and one patient organization. The evidence base from clinical trials and meta-analyses was summarized and subjected to a structured consensus-process in accordance with the regulations of the Association of Scientific Medical Societies in Germany (AWMF) and the methodological requirements of the "German instrument for methodological guideline appraisal". Results: This consensus-based guideline (S2k classification according to the AWMF guidance manual and rules) resulted in seven on-topic statements and 17 specific recommendations relevant to the classification, assessment and therapy of pain directly or indirectly caused by SCI. Recommended therapeutic approaches comprise pharmacological (e.g. nonsteroidal anti-inflammatory drugs or anticonvulsants) and non-pharmacological (e.g. physical activity or psychotherapeutic techniques) strategies for both nociceptive and neuropathic pain. Discussion: Assessment of SCI-related pain is standardized and respective methods in terms of examination, classification and grading of pain are already in use and validated in German language. In contrast, valid, evidence-based and efficient therapeutic options are limited and ask for further clinical studies, ideally randomized controlled trials and meta-analyses.

ABSTRACT

INTRODUCTION: To investigate whether MR-defecography can be employed in sensorimotor complete spinal cord injury (SCI) subjects as a potential diagnostic tool to detect defecational disorders associated with neurogenic bowel dysfunction (NBD) using standard parameters for obstructed defecation. MATERIAL AND METHODS: In a prospective single centre clinical trial, we developed MR-defecography in traumatic sensorimotor complete paraplegic SCI patients with upper motoneuron type injury (neurological level of injury T1 to T10) using a conventional 3T scanner. Defecation was successfully induced by eliciting the defecational reflex after rectal filling with ultrasonic gel, application of two lecicarbon suppositories and digital rectal stimulation. Examination was performed with patients in left lateral decubitus position using T2-weighted turbo spin echo sequence in the sagittal plane at rest (TE 89ms, TR 3220ms, FOV 300mm, matrix 512×512, ST 4mm) and ultrafast-T2-weighted-sequence in the sagittal plane with repeating measurements (TE 1.54ms, TR 3.51ms, FOV 400mm, matrix 256×256, ST 6mm). Changes of anorectal angle (ARA), anorectal descent (ARJ) and pelvic floor weakness were documented and measured data was compared to reference values of asymptomatic non-SCI subjects in the literature to assess feasibility. RESULTS: MR-defecography provides evaluable imaging sequences of the induced evacuation phase in SCI patients. Measurement results for ARA, ARJ, hiatal width (H-line) and hiatal descent (M-line) deviate significantly from reference values in the literature in asymptomatic subjects without SCI. The overall mean values in our study for SCI patients were: ARA (rest) 127.3°, ARA (evacuation) 137.6°, ARJ (rest) 2.4cm, ARJ (evacuation) 4.0cm, H-line (rest) 7.6cm, H-line (evacuation) 8.1cm, M-line (rest) 2.6cm, M-line (evacuation) 4.2cm. CONCLUSIONS: MR-defecography is feasible in sensorimotor complete SCI patients. Individual MR-defecography findings may help to determine specific therapeutical options for respective patients suffering from severe NBD.

ABSTRACT

After traumatic spinal cord injury, an acute phase triggered by trauma is followed by a subacute phase involving inflammatory processes. We previously demonstrated that peripheral serum cytokine expression changes depend on neurological outcome after spinal cord injury. In a subsequent intermediate phase, repair and remodeling takes place under the mediation of growth factors such as Insulin-like Growth Factor 1 (IGF-1). IGF-1 is a promising growth factor which is thought to act as a neuroprotective agent. Since previous findings were taken from animal studies, our aim was to investigate this hypothesis in humans based on peripheral blood serum. Forty-five patients after traumatic spinal cord injury were investigated over a period of three months after trauma. Blood samples were taken according to a fixed schema and IGF-1 levels were determined. Clinical data including AIS scores at admission to the hospital and at discharge were collected and compared with IGF-1 levels. In our study, we could observe distinct patterns in the expression of IGF-1 in peripheral blood serum after traumatic spinal cord injury regardless of the degree of plegia. All patients showed a marked increase of levels seven days after injury. IGF-1 serum levels were significantly different from initial measurements at four and nine hours and seven and 14 days after injury, as well as one, two and three months after injury. We did not detect a significant correlation between fracture and the IGF-1 serum level nor between the quantity of operations performed after trauma and the IGF-1 serum level. Patients with clinically documented neurological remission showed consistently higher IGF-1 levels than patients without neurological remission. This data could be the base for the establishment of animal models for further and much needed research in the field of spinal cord injury.

ABSTRACT

Pro- and anti-inflammatory cytokines might have a large impact on the secondary phase and on the neurological outcome of patients with acute spinal cord injury (SCI). We measured the serum levels of different cytokines (Interferon-γ, Tumor Necrosis Factor-α, Interleukin-1ß, IL-6, IL-8, IL-10, and Vascular Endothelial Growth Factor) over a 12-week period in 40 acute traumatic SCI patients: at admission on average one hour after initial trauma; at four, nine, 12, and 24 h; Three, and seven days after admission; and two, four, eight, and twelve weeks after admission. This was done using a Luminex Performance Human High Sensitivity Cytokine Panel. SCI was classified using the American Spinal Injury Association (ASIA) Impairment Scale (AIS) at time of admission and after 12 weeks. TNFα, IL-1ß, IL-6, IL-8, and IL-10 concentrations were significantly higher in patients without neurological remission and in patients with an initial AIS A (p < 0.05). This study shows significant differences in cytokine concentrations shown in traumatic SCI patients with different neurological impairments and within a 12-week period. IL-8 and IL-10 are potential peripheral markers for neurological remission and rehabilitation after traumatic SCI. Furthermore our cytokine expression pattern of the acute, subacute, and intermediate phase of SCI establishes a possible basis for future studies to develop standardized monitoring, prognostic, and tracking techniques.

ABSTRACT

BACKGROUND: The compact Motorized orthosis for home rehabilitation of Gait (MoreGait) was developed for continuation of locomotion training at home. MoreGait generates afferent stimuli of walking with the user in a semi-supine position and provides feedback about deviations from the reference walking pattern. OBJECTIVE: Prospective, pre-post intervention, proof-of-concept study to test the feasibility of an unsupervised home-based application of five MoreGait prototypes in subjects with incomplete spinal cord injury (iSCI). METHODS: Twenty-five (5 tetraplegia, 20 paraplegia) participants with chronic (mean time since injury: 5.8 ± 5.4 (standard deviation, SD) years) sensorimotor iSCI (7 ASIA Impairment Scale (AIS) C, 18 AIS D; Walking Index for Spinal Cord Injury (WISCI II): Interquartile range 9 to 16) completed the training (45 minutes / day, at least 4 days / week, 8 weeks). Baseline status was documented 4 and 2 weeks before and at training onset. Training effects were assessed after 4 and 8 weeks of therapy. RESULTS: After therapy, 9 of 25 study participants improved with respect to the dependency on walking aids assessed by the WISCI II. For all individuals, the short-distance walking velocity measured by the 10-Meter Walk Test showed significant improvements compared to baseline (100%) for both self-selected (Mean 139.4% ± 35.5% (SD)) and maximum (Mean 143.1% ± 40.6% (SD)) speed conditions as well as the endurance estimated with the six-minute walk test (Mean 166.6% ± 72.1% (SD)). One device-related adverse event (pressure sore on the big toe) occurred in over 800 training sessions. CONCLUSIONS: Home-based robotic locomotion training with MoreGait is feasible and safe. The magnitude of functional improvements achieved by MoreGait in individuals with iSCI is well within the range of complex locomotion robots used in hospitals. Thus, unsupervised MoreGait training potentially represents an option to prolong effective training aiming at recovery of locomotor function beyond in-patient rehabilitation.

ABSTRACT

OBJECTIVES: To determine the effectiveness of platelet-rich plasma (PRP) in the treatment of nonhealing fistula in spinal cord-injured patients. STUDY DESIGN: This was a pilot study of 15 spinal cord-injured patients with chronic pressure ulcers (PrUs) and nonhealing fistulas treated with PRP. SETTING: Germany, Rheinland Pfalz, BG Trauma Center Ludwigshafen METHODS: The authors treated 15 patients with PRP who had nonhealing fistulas due to multiple surgical closures of PrUs. According to the National Pressure Ulcer Advisory Panel's stages, 12 patients had Stage III PrUs, and 3 patients had Stage IV PrUs. RESULTS: After 1 week of treatment with PRP, the authors observed low levels of secretion from the fistulas. After 2 weeks, they noted no further secretion from the fistulas. A magnetic resonance imaging control investigation after 3 weeks showed the complete disappearance of the fistulas. No negative effects and no allergic reactions were noted in the use of PRP. CONCLUSION: The authors' results suggest that the application of PRP in combination with debridement is an effective therapy option and good alternative to recurrent surgical interventions for treating nonhealing fistulas resulting from the surgical closure of PrUs.

ABSTRACT

OBJECTIVE: To determine serum concentrations of soluble CD95 ligand (sCD95L) in patients with traumatic spinal cord injury. METHODS: Patients with traumatic spinal cord injury were recruited. Blood was collected on admission to hospital and at 4 h, 9 h, 12 h, 24 h, 3 days, 7 days, and 2, 4, 8 and 12 weeks postadmission. Serum concentrations of sCD95L were determined via immunoassay. RESULT: The study included 23 patients. Mean sCD95L concentrations were significantly lower at 4 h, 9 h, 12 h and 24 h than at admission, and were significantly higher at 8 and 12 weeks, compared with admission. CONCLUSION: The serum sCD95L concentration fell significantly during the first 24 h after traumatic spinal cord injury. Concentrations then rose, becoming significantly higher than admission levels at 8 weeks. sCD95L may represent a possible therapeutic target for traumatic spinal cord injury.

ABSTRACT

BACKGROUND: Injuries of thoracic vertebrae in multiple trauma patients are often accompanied by severe thoracic injuries and sensorimotor deficits. However, until now, it is not clear whether and how the severity of trauma influences the neurologic and functional outcome in paraplegic patients during the first year after the trauma. The aim of the study was to compare two cohorts of multiple injured paraplegic patients with and without conversion in the American Spinal Injury Association Impairment Scale (AIS) with regard to the severity of spinal trauma, the severity of thorax trauma, the type of fracture, and the functional outcome 1 year after the date of injury. METHODS: Twenty-one traumatic paraplegic patients (neurologic level T1-T12) were included in the study based on a retrospective analysis of the Heidelberg European Multicenter Study about Spinal Cord Injury database (www.emsci.org) from 2002 to 2007. In all patients, the Polytraumaschluessel (PTS), the AO classification, the AIS, and the Spinal Cord Independence Measure were collected. Patients with no change in the AIS (group 1, n=14) were compared with patients with AIS changes (group 2, n=7), and t test and χ test were performed (p<0.05). RESULTS: Differences in both groups concerning fracture classification were confirmed (p=0.046). A relation between neurologic improvement in the AIS and the severity of trauma (p=0.058) after 1 year was not found. The subitem PTST in the thoracic area showed statistical significance comparing the two groups (p=0.005). Both groups significantly improved functionally (Spinal Cord Independence Measure, p=0.035) during the first year but with no significant difference between the groups after 1 year. CONCLUSIONS: Our data suggest that functional improvement is achieved independently from neurologic recovery. The combined assessment of the PTS, the AO classification, and the AIS in multiple-injured paraplegic patients can contribute to provide a better prognostication of the neurologic changes during rehabilitation and the outcome after 1 year than the AIS alone.

ABSTRACT

In incomplete spinal cord injured subjects, task-oriented training regimes are applied for enhancement of neuroplasticity to improve gait capacity. However, a sufficient training intensity can only be achieved during the inpatient phase, which is getting shorter and shorter due to economic restrictions. In the clinical environment, complex and expensive robotic devices have been introduced to maintain the duration and the intensity of the training, but up to now only a few exist for continuation of automated locomotion training at home. For continuation of the automated locomotion training at home prototypes of the compact, pneumatically driven orthosis MoreGait have been realized, which generate the key afferent stimuli for activation of the spinal gait pattern generator. Artificial pneumatic muscles with excellent weight-to-force ratio and safety characteristics have been integrated as joint actuators. Additionally, a Stimulative Shoe for generation of the appropriate foot loading pattern has been developed without the need for verticalization of the user. The first results of the pilot study in eight chronic incomplete spinal cord injured subjects indicate that the home-based therapy is safe and feasible. The therapy related improvements of the walking capacity are in the range of locomotion robots used in clinical settings.

ABSTRACT

Kyphoplasty is a recognized treatment option in the management of symptomatic osteoporotic compression fractures, osteolytic vertebral metastases or haemangioma. To our knowledge, kyphoplasty with polymethylmethacrylate in a patient with type I osteogenesis imperfecta (OI) and a vertebral compression fracture has not been reported so far. We report on a 58-year-old patient with type I OI and a vertebral compression fracture at L2 with undislocated posterior vertebral wall and an additional older L1 fracture. Because of severe back pain resistant to conservative therapy over 5 months the indication for percutaneous kyphoplasty was made. Preoperative adjacent endplates of L2 were nearly parallel. Radiologically a minimal loss of height of the L2 vertebra was seen without adjacent fractures at 9 months follow-up. A slight increase of the preoperative kyphotic angle of overlying vertebrae L1 (8.7 degrees/10.3 degrees) and T12 (10.4 degrees/11.0 degrees) was apparent. The visual analogue scale showed decrease of low back pain from 10 to 2 allowing mobilization with a walking frame. Kyphoplasty constitutes a minimal invasive therapeutic alternative in the treatment of vertebral fractures in type I OI and pain, resistant to conservative treatment. Similar to the results of osteoporotic fractures the immediate reduction of pain and stabilization of the fracture in undislocated fragments can be achieved. No adjacent fractures occurred 9 months postoperatively after kyphoplasty in type I OI. Preoperative parallelism of the endplates seems to protect from adjacent fractures.

ABSTRACT

STUDY DESIGN: Retrospective clinical study. OBJECTIVE: The aim of this study was to examine whether the Tokuhashi score correlates with the neurologic outcome in early surgical treatment in metastatic spinal cord compression (MSCC). A retrospective analysis of 35 consecutive incomplete tetraplegic and paraplegic patients with vertebral metastases (VM) and spinal cord compression (SCC) was performed. SUMMARY OF BACKGROUND DATA: MSCC is a challenging problem in VM and constitutes an oncologic emergency. The Tokuhashi score has been modified recently and seems to constitute the best method of prediction for real survival in patients with VM. Until now the influence of the neurologic status as a prognostic factor has been discussed controversially. METHODS: Data of 35 patients with VM and incomplete tetraplegia or paraplegia, who underwent surgical treatment, were reviewed retrospectively from 2005 to 2006 at our hospital. All patients were classified among the American Spinal Injury Association (ASIA) Impairment Scale (AIS) before and after surgery and at the follow-up. Data were analyzed with SPSS 15.0 and correlation coefficients (Spearman rho) were computed. RESULTS: Analysis showed that 19 patients (54.3%) with an average Tokuhashi score of 9 showed an improvement in the AIS, whereas 12 (34.3%) patients with an average score of 8 had no change and 4 (11.4%) patients with a score of 7 had deterioration. AIS changes showed a positive correlation with Tokuhashi score (r = 0.33; P = 0.048). CONCLUSION: Our clinical observation suggests that patients with spinal metastases and a high Tokuhashi score benefit from surgical treatment with moderate improvement in sensomotoric function even in a heterogenic collective.

ABSTRACT

By restricting analysis to single averaged strides considered to be characteristic for the individual under investigation, current methods in gait analysis do not exploit the full dynamics of continuous locomotion. Therefore, a novel approach is presented that is based on long-term measurements of kinematic data during treadmill walking. The method consists of reconstructing the system attractor in the embedding space and then analyzing its geometric structure. Estimating the dimension of movement trajectories correlates well with the notion of controlling multiple degrees of freedom during performance of complex movement tasks such as walking. The influence of walking speed on the complexity of physiologic walking was investigated in 10 healthy subjects walking on a treadmill at seven fixed speeds. The results suggest that human walking becomes more complex at slower speeds. This may be associated with results from EMG studies demonstrating more irregular EMG patterns at very slow walking speeds. This study emphasizes that tools from non-linear dynamics are well suited for providing more insight into motor control in humans.

ABSTRACT

Recently, locomotion therapy on a treadmill has become part of rehabilitation programs for neurological gait disorders (spinal cord injury, hemiplegia). Instrumental gait analysis is an important tool for quantification of therapy progress in terms of functional changes in a patient's gait patterns. Whereas most of current applications focus on diagnostic assessment of gait, the current paper presents an extension of movement analysis offering enhanced therapeutic options. Specifically, the conceptual basis for application of real-time movement feedback in rehabilitation medicine is outlined and is put into context with recent developments in the field. A first technical realization of these concepts is presented and first results are reported. Furthermore, open questions towards a universal environment for movement feedback in rehabilitation medicine are discussed and future lines of research are identified.

ABSTRACT

A methodological modular framework is presented for automated assessment of gait patterns. The processing steps of data selection, gait parameter calculation and evaluation are not limited to a specific field of application and are largely independent of case-based clinical expert knowledge. For these steps, a variety of mathematical methods was used and the validity of the approach to assess gait parameters tested by applying it to the clinical problem of Botulinum Toxin A (BTX-A) treatment of the spastic equinus foot. A set of 3670 parameters was ranked by relevance for classification of a group of 42 diplegic cerebral palsy (CP) patients and an age-matched reference group. The same procedure was performed for pre- and post-therapeutic data sets of these patients. Gait parameters of high relevance coincided well with results of previous studies based on partly manual and more subjective parameter selection. A norm distance measure is introduced to facilitate the quantification of deviations from a normal walking pattern and can be used as an overall scalar measure to evaluate differences in gait patterns or as a set of measures attributing each joint angle separately.

ABSTRACT

The aim of the present study was to demonstrate the first time the non-invasive restoration of hand grasp function in a tetraplegic patient by electroencephalogram (EEG)-recording and functional electrical stimulation (FES) using surface electrodes. The patient was able to generate bursts of beta oscillations in the EEG by imagination of foot movement. These beta bursts were analyzed and classified by a brain-computer interface (BCI) and the output signal used to control a FES device. The patient was able to grasp a cylinder with the paralyzed hand.

ABSTRACT

PURPOSE: The purpose of this study was to answer the question of whether a course of in-patient rehabilitation of 4-6 weeks results in a significant postural improvement in patients with a structural kyphosis. Since all clinical measuring parameters are liable to high margins of error and measuring the surface with the formetric system has shown high reliability in previous studies, this system has been used to evaluate the results of rehabilitation in patients with Scheuermann's disease. MATERIALS AND METHOD: A pre-/post-interventional study was undertaken including only patients (n = 136) with Scheuermann's kyphosis and a thoracic curve pattern. 62 female patients with an average age of 19 years and 74 male patients of average age 20 years were diagnosed with the Formetric system before an in-patient rehabilitation programme of 4-6 weeks. For this study, the maximal kyphotic angle was evaluated. RESULTS: The average kyphotic angle as measured by the surface topography system before inpatient rehabilitation was 60.7 degrees (SD 11.2) and after 54.9 degrees (SD 12.1) for the whole sample of 136 patients. The improvements where highly significant in the t-test. In the cases of the female patients, the maximal kyphotic angle decreased from 62 degrees to nearly 54 degrees; in the cases of the male patients it had decreased from 60 degrees to nearly 55 degrees by the end of the programme. DISCUSSION: After the in-patient treatment, the kyphotic angle decreased very significantly. The range of change was far greater than the margin of error and, thus, the following conclusion may be reached: In-patient rehabilitation with an intensive programme of treatment may result in a correction of structural kyphoses in which there are clear signs of Scheuermann's disease. Consequently in-patient rehabilitation is recommended for adolescents in cases of Scheuermann's kyphoses.

ABSTRACT

For the follow-up of patients with sagittal spinal deformities and postural disorders, we do not have well validated measuring systems at our disposal. All clinical measuring parameters are liable to a high margin of error. With a growing number of patients suffering from postural disorders and kyphoses, we have to look for other possibilities to monitor changes of the back, as well as in the short term, without the support of X-rays. As the measuring of the surface with the Formetric system showed a high measurement reliability in previous studies, we used this system to demonstrate the rehabilitation results of our patients with Scheuermann's disease. An intervention study (pre-/post-design) was undertaken including the following material.: 62 female patients with Scheuermann's disease and an average age of 19 years old and 74 male patients with Scheuermann's disease and an average age of 20 years old were measured with the Formetric system before an in-patient rehabilitation of four to six weeks. For this study, we evaluated the maximal kyphotic angle as shown by the system. In the case of female patients, the maximal kyphotic angle decreased highly significantly from sixty two to nearly fifty four degrees. In the case of the male patients, it decreased from sixty to nearly fifty five degrees at the end. It showed that the surface measuring system with the Formetric System is a reliable instrument for the follow-up of sagittal postural disorders and kyphoses for the present study, especially in the case of Scheuermann's disease. In praxis, the use of this measurement is very easy, we obtain the measurement results very quickly, so that the evaluation of data is not very time consuming. After the in patient treatment, the kyphotic angle decreased highly significantly. The changes range far above the margin of error, thus the following conclusions are justified. Firstly, the Formetric System is the appropriated instrument for the follow-up of postural disorder and kyphoses. Secondly, the in-patient rehabilitation with an intensive treatment program may result in a correction of also structural kyphoses with sure signs of Scheuermann's disease. Thus we recommend an in-patient rehabilitation in adolescent age in case of Scheuermann kyphoses with large curvatures and in case of Scheuermann kyphoses in adults suffering from pain.

ABSTRACT

In our rehabilitation centre, the treatment of Scheuermann's disease consists of a daily postural education, lasting several hours. As for pain therapy, we mainly apply physiotherapeutic methods with osteopathy, manual therapy, Mc Kenzie and Brügger. In addition, we offer psychological help for pain relief. In case of severe chronic pain, we additionally treat it with acupuncture. Pain therapy with medication is only performed in rare cases. The aim of the present study was to find out if such an intensive rehabilitation programme had any effect on pain level in patients with Scheuermann's disease. An Intervention study (pre-/post-design) was undertaken including the following material: 351 patients suffering from Scheuermann's disease reported their pain level before and after an inpatient treatment. For this aim, we used a visual analog scale (VAS), a numerical scale (NS), a standardised adjective scale (VRS) and a pain frequency scale. In our group, there were 61 female patients with a thoracolumbar Scheuermann's disease, 121 female patients with a thoracic Scheuermann's disease, 92 male patients with a thoracolumbar Scheuermann's disease and 77 male patients with a thoracic Scheuermann's disease. The average age was 17 to 21 years old with an average kyphotic angle varying in the individual groups between 53 and 64 degrees. In the case of the numerical pain severity scale, pain severity was for example 2,9 in female patients with thoracolumbar Scheuermann's disease. In female patients with thoracic Scheuermann's disease, pain severity was also at 2.9. In male patients with thoracolumbar Scheuermann's disease, it was at 2.0 and in male patients with thoracic Scheuermann's disease, it was at 1.9. This numerical pain scale showed highly significant changes in pain severity: 2.1 in female patients with thoracolumbar Scheuermann's disease, 1.9 in female patients with thoracic Scheuermann's disease, 1.4 in male patients with thoracolumbar Scheuermann's disease and 1.8 in male patients with thoracic Scheuermann's disease. There was also a significant decrease in pain frequency. Seen as a whole, each scale showed a pain reduction between 16 and 32%, which is significant in all the cases and even highly significant in some cases. The in patient rehabilitation seems to have a positive effect on pain level in patients with Scheuermann's disease. In case of Scheuermann's disease in adult age, treatment is only indicated when patients suffer from pain. For those reasons, an in-patient intensive program of rehabilitation in a clinic with adequate quality structure should be considered.
