RESUMEN
Background and study aims Colonoscopies in patients with spinal cord injury (SCI) frequently remain incomplete. This study aimed to evaluate the feasibility and impact of water exchange colonoscopy (WE) in patients with SCI. Patients and methods Three matched groups, each of 31 patients (WE in SCI patients [WE-SCI]) and in the general population (WE-GP), carbon dioxide-based colonoscopy in SCI patients (CO 2 -SCI)) were analyzed retrospectively. Results Intubation of the cecum and the terminal ileum was achieved in every case in both WE groups. The intubations among the CO 2 -SCI patients succeeded in 29 cases (93.5 %, ns) and 20 cases (64.5 %, P <0.001), respectively. The cecal insertion time (23:17 ± 10:17 min vs. 22:12 ± 16:48 min) and bowel preparation during cecal insertion did not differ between WE-SCI groups. Insertion in the general population was faster (13:38 ± 07:00 min, P <.001) and cleanliness was better. Both WE-SCI groups showed significantly better cleansing results during drawback; the improvement in cleanliness was highest in the WE-SCI (based on the five-step scale 1.4 ± 0.8 vs. 0.8 ± 0.8, P = 0.001). Conclusions The WE in SCI patients is feasible and safe and has the potential to improve the quality of colonoscopies substantially.
RESUMEN
STUDY DESIGN: Observational study. OBJECTIVES: To evaluate the perceptions of patients requiring a tracheostomy tube and to identify possible different perceptions in critically ill patients with tracheostomy tubes who have acute (ASCI) or chronic spinal cord injuries (CSCI). SETTING: Medical and surgical intensive care units (ICU) and intermediate care unit of the BG University Hospital Bergmannsheil Bochum, Germany. METHODS: Patients who met the inclusion criteria completed a 25-item questionnaire on two consecutive days regarding their experiences and perceptions in breathing, coughing, pain, speaking, swallowing, and comfort of the tracheostomy tube. RESULTS: A total of 51 persons with ASCI (n = 31) and CSCI (n = 20) were included with a mean age of 53 years. Individuals with ASCI reported significantly more frequent pain and swallowing problems as compared to individuals with CSCI (p ≤ 0.014) at initial assessment. There were no differences between ASCI and CSCI reported with respect to speaking and overall comfort. CONCLUSIONS: It is necessary to regularly assess the perceptions of critically ill patients with tracheostomy tubes with ASCI or CSCI in the daily ICU care routine. We were able to assess these perceptions in different categories. For the future, evaluating the perception of individuals with SCI and a tracheostomy should be implemented to their daily routine care. TRIAL REGISTRATION: DRKS00022073.

STUDY DESIGN: Retrospective matched case-control study including patients with spinal cord injury who presented with an anus-near pressure injury. Two groups were formed based on the presence of a diverting stoma. OBJECTIVES: To evaluate the primary microbial colonisation and secondary infection of anus-near pressure injuries depending on the presence of a pre-existing diverting stoma and to investigate the effect on the wound healing. SETTING: University hospital with a spinal cord injury unit. METHODS: A total of 120 patients who had undergone surgery of an anus-near decubitus stage 3 or 4 were included in a matched-pair cohort study. Matching was realised according to age, gender, body mass index and general condition. RESULTS: The most common species in both groups was Staphylococcus spp.(45.0%). The only significantly different primary colonisation affected Escherichia coli, that was found in the stoma patients less often (18.3 and 43.3%, p < 0.01). A secondary microbial colonisation occurred in 15.8% and was equally distributed, except for Enterococcus spp. that was present in the stoma group only (6.7%, p < 0.05). The time to complete cure took longer in the stoma group (78.5 versus 57.0 days, p < 0.05) and was associated with a larger ulcer size (25 versus 16 cm2, p < 0.01). After correction for the ulcers' size, there was no association to outcome parameters such as overall success, healing time or adverse events. CONCLUSIONS: The presence of a diverting stoma alters the microbial flora of an anus-near decubitus slightly without impact on the healing process.

OBJECTIVE: Recent studies reveal that Hybrid Assistive Limb (HAL®) locomotion training in paraplegic patients suffering from chronic spinal cord injury (SCI) induces improvements in functional and ambulatory mobility. The purpose of this study was to determine the safety, feasibility, and functional effectiveness of HAL® locomotion training in the initial rehabilitation of acute SCI patients. This clinical trial represents the first systematic intervention worldwide for acute SCI patients using a neurologically controlled exoskeleton. DESIGN: Single center, prospective study. SETTING: BG University Hospital Bergmannsheil, Bochum, Germany. PARTICIPANTS: Fifty acute SCI patients (14 women, 36 men). INTERVENTIONS: All participants received a daily (5 times/week) HAL® exoskeleton supported training for 12 weeks (mean amount of training sessions 60.4 ± 30.08). OUTCOME MEASURES: Functional outcome for overground walking was monitored using the 10-m-walk test (10 MWT) combined with the WISCI II score, 6-minute-walk test (6 MWT) and the timed-up and go test (TUG test). Treadmill-related parameters (speed, distance and walking time) and the Lower Extremity Motor Score (LEMS) were recorded separately. RESULTS: Significant improvements were observed for HAL®-associated (walking time, distance and speed) and for functional outcomes (10 MWT, 6 MWT and TUG-test). WISCI-II-Score and the LEMS increased significantly compared with the status prior to training. CONCLUSION: HAL® locomotion training is feasible and safe in the rehabilitation of acute SCI patients. The HAL® exoskeleton enables the patient to perform effective treadmill training and leads to improvements in functional and ambulatory mobility. However, spontaneous recovery vs training-related effects remain unclear and findings should not be extrapolated beyond the acute in-patient rehabilitation setting.Trial registration: German Clinical Trials Register identifier: DRKS00010250..

The development of increasingly more complex computer and electromotor technologies enables the increasing use and expansion of robot-assisted systems in trauma surgery rehabilitation; however, the currently available devices are rarely comprehensively applied but are often used within pilot projects and studies. Different technological approaches, such as exoskeletal systems, functional electrical stimulation, soft robotics, neurorobotics and brain-machine interfaces are used and combined to read and process the communication between, e.g., residual musculature or brain waves, to transfer them to the executing device and to enable the desired execution.Currently, the greatest amount of evidence exists for the use of exoskeletal systems with different modes of action in the context of gait and stance rehabilitation in paraplegic patients; however, their use also plays a role in the rehabilitation of fractures close to the hip joint and endoprosthetic care. So-called single joint systems are also being tested in the rehabilitation of functionally impaired extremities, e.g., after knee prosthesis implantation. At this point, however, the current data situation is still too limited to be able to make a clear statement about the use of these technologies in the trauma surgery "core business" of rehabilitation after fractures and other joint injuries.For rehabilitation after limb amputation, in addition to the further development of myoelectric prostheses, the current development of "sentient" prostheses is of great interest. The use of 3D printing also plays a role in the production of individualized devices.Due to the current progress of artificial intelligence in all fields, ground-breaking further developments and widespread application possibilities in the rehabilitation of trauma patients are to be expected.

INTRODUCTION: There is not much data on traumatic spinal cord injuries sustained during sports in Germany. This study aims to present the frequency of traumatic spinal cord injuries with neurological involvement within various sports over the past 22 years. METHODS: This study is a retrospective evaluation of traumatic spinal cord injuries (tSCI) in sports sustained in the past 22 years. The study was performed by a German level 1 trauma centre with a department for spinal cord injuries. The files of inpatients treated in the years 1998 to 2020 were evaluated with regard to patients' histories and traumatic spinal cord injuries. In addition, injury location and gender distribution were recorded. RESULTS: A total of 1630 patients with traumatic spinal cord injuries with neurological involvement were recorded. Of the 1630 patients, N=116 (7.1%) had had sports accidents. The age of this subpopulation was significantly younger at 41 years (p=0.05) than the age of the total group of tSCI at 50 years. A more detailed analysis of the sports injuries showed that in descending order equestrian sports (N=22), winter (N=18), air (N=16), motor sports (N=16) and cycling (N=15) were the most common causal factors for these particularly serious spinal injuries. As regards the distribution of the location of the spinal cord injury with a view to the type of sports practiced, a significant result was shown in aerial sports, with patients from this group mainly having had lumbar spine injuries (p <0.01), and in diving with cervical spine injuries (p=0). Gender distribution in the individual sports shows a significant difference in equestrian sports (male < female, p <0.01) as well as a significant difference in air sports (male > female, p = 0.05) and cycling (male > female, p=0.07). CONCLUSION: In summary, equestrian sports is the most common cause of spinal cord injuries with neurological involvement in the sports sector with a higher proportion of female participants, although the proportion of female patients is smaller compared with male patients in the section of traumatic spinal cord injuries. Winter (N=18), air (N=16), motor sports (N=15) and cycling (N=15) come next in descending order.Patients with traumatic spinal cord injuries caused by sports accidents are significantly younger than the entirety of patients with traumatic spinal cord injuries.

STUDY DESIGN: Retrospective survey. OBJECTIVES: Purpose of this study was to explore whether bowel and bladder management can be influenced by locomotion therapy with HAL Robot Suit. METHODS: 35 subjects with acute (< one year since injury, n = 13) or chronic (> one year since injury, n = 22) incomplete paraplegia (American Spinal Injury Association Impairment Scale (AIS) B, n = 1 / AIS C, n = 22 / AIS D, n = 7) or complete paraplegia (AIS A, n = 5) with zones of partial preservation (ZPP) participated. A retrospective survey was carried out asking for bowel incontinence (Wexner Score), constipation (Cleveland Clinic Constipation Scoring System (CCCS)) and bladder function (self-developed questionnaire) before and after completing a training period of 12 weeks with HAL. RESULTS: Wexner Score over all patients and for group of chronic patients decreased significantly. For group of acute patients Wexner Score decreased insignificantly. Patients from both groups with higher baseline scores could decrease significantly. CCCS was insignificantly reduced for all patients, group of acute and group of chronic patients. For subgroup of chronic patients with higher baseline scores, CCCS decreased at end of training period missing out significance. The self-developed questionnaire showed an improvement in bladder function in 28.24% of all patients, 31.43% of chronic patients, and 23.08% of acute patients. CONCLUSIONS: Our findings show trends of enhanced bladder and bowel function following exoskeleton training. Patients with higher baseline scores in Wexner Score and CCCS seem to benefit more than those with mild to moderate scores.
RESUMEN
BACKGROUND: Although the use of vasopressors to maintain haemodynamic goals after acute spinal cord injury (SCI) is still recommended, evidence regarding the target values and possible risks of this practice is limited, and data on haemodynamic parameters unaffected by catecholamines are rare. In this pilot study, we show the haemodynamic profile of patients with acute SCI mainly unaffected by vasopressor use and other factors that influence the cardiovascular system. METHODS: From March 2018 to March 2020, we conducted a prospective, single-centre pilot study of 30 patients with acute SCI. Factors that could affect the cardiocirculatory system other than SCI (sepsis, pre-existing heart disease or multiple trauma) led to exclusion. A total of 417 measurements were performed using the PiCCO™ system. RESULTS: The mean systemic vascular resistance index (SVRI, 1447.23 ± 324.71 dyn*s*cm-5*m2), mean central venous pressure (CVP, 10.69 ± 3.16) and mean global end-diastolic volume index (GEDVI, 801.79 ± 158.95 ml/m2) deviated from the reference range, while the mean cardiac index (CI), mean stroke volume index (SVI), mean arterial pressure (MAP), and mean heart rate (HR) were within the reference range, as indicated in the literature. A mixed model analysis showed a significant negative relationship between norepinephrine treatment and MAP (83.97 vs. 73.69 mmHg, p < 0.001), SVRI (1463.40 vs. 1332.14 dyn*s*cm-5*m2, p = 0.001) and GEDVI (808.89 vs. 759.39 ml/m2, p = 0.001). CONCLUSION: These findings could lead to an adaptation of the target range for SVRI and MAP in patients with acute SCI and therefore reduce the use of vasopressors.

INTRODUCTION: The first weeks after total knee arthroplasty (TKA) are crucial for the functional outcome. To improve knee mobility, a continuous passive motion (CPM) motor rail is commonly used during in-hospital rehabilitation. The single-joint hybrid assistive limb (HAL-SJ) is a new therapy device. The aim of the study was to improve patients' range of motion (ROM), mobility, and satisfaction using the active-assistive support of the HAL-SJ. MATERIALS AND METHODS: Between 09/2017 and 10/2020, 34 patients, who underwent TKA and matched the inclusion criteria, were randomized into study (HAL-SJ) and control (CPM) group. Treatment began after drain removal and was carried out until discharge. Primary outcome parameters were raised pre- and postoperatively and included the Oxford knee score (OKS), visual analog scale (VAS), and acquired range of motion. Furthermore complications caused by the device were recorded. RESULTS: OKS increased in both groups postoperatively, but only significantly in the HAL-SJ group. Postoperative pain improved in both groups without significant differences. Flexion improvement was significant in both groups between days 3/7 and 8 weeks postoperatively. We did not encounter any complications related to HAL-SJ. CONCLUSIONS: In conclusion, use of the HAL-SJ during rehabilitation in the early postoperative period after TKA was safe without disadvantages compared to the control group and seems to have advantages in terms of daily life impairment.

STUDY DESIGN: Retrospective study. OBJECTIVES: To analyze factors associated with major complications (MC) in patients with ankylosing spondylitis (AS) undergoing surgical management for a spine fracture. METHODS: Included were all persons with spine fractures and AS in a teriary health care center between 2003 and 2019. Clinical data and MC were characterized with descriptive characteristics. Multivariable analyses were used to find factors associated with MC. RESULTS: In total, 174 traumatic fracture incidents in 166 patients with AS were included, with a mean patient age of 70.7 ± 13.1 years. The main reason for spine fracture was minor trauma (79.9%). Spinal cord injuries (SCI) were described in 36.7% of cases. The majority of patients (54.6%) showed more than one fracture of the spine, with cervical fractures being the most common (50.5%). Overall, the incidences of surgical site infection, implant failure, nosocomial pneumonia (NP), and mortality were 17.2%, 9.2%, 31%, and 14.9%, respectively. ICU stay > 48 hours was associated with MC (including death). Posterior approach for spondylodesis, ICU stay > 48 hours and cervical SCI were related to MC (excluding death). Age > 70 years, NP and Charlson comorbidity index > 5 points were associated with in-hospital mortality. CONCLUSIONS: Patients with AS and surgical treatment of spine fractures are at high risk for MC. Therefore, our results might give physicians better insight into the incidence and sequelae of major complications and therefore might improve patient and family expectations.
RESUMEN
Mind-controlled wheelchairs are an intriguing assistive mobility solution applicable in complete paralysis. Despite progress in brain-machine interface (BMI) technology, its translation remains elusive. The primary objective of this study is to probe the hypothesis that BMI skill acquisition by end-users is fundamental to control a non-invasive brain-actuated intelligent wheelchair in real-world settings. We demonstrate that three tetraplegic spinal-cord injury users could be trained to operate a non-invasive, self-paced thought-controlled wheelchair and execute complex navigation tasks. However, only the two users exhibiting increasing decoding performance and feature discriminancy, significant neuroplasticity changes and improved BMI command latency, achieved high navigation performance. In addition, we show that dexterous, continuous control of robots is possible through low-degree of freedom, discrete and uncertain control channels like a motor imagery BMI, by blending human and artificial intelligence through shared-control methodologies. We posit that subject learning and shared-control are the key components paving the way for translational non-invasive BMI.
RESUMEN
STUDY DESIGN: Retrospective cohort study including spinal cord injured patients with anus-near pressure ulcers. OBJECTIVE: The primary objective was to evaluate the impact of stool diversion via stoma on the decubital wound healing. Secondary objectives included the risk of complications and ulcer recurrence. Associations between the wound healing and potentially interfering parameters were determined. SETTING: University hospital with a spinal cord injury unit. METHODS: A total of 463 consecutive patients who presented with a decubitus were retrospectively included. Patients with and without a stoma were compared using descriptive and explorative statistics including multiple regression analysis. RESULTS: The severity of the pressure ulcers was determined as stage 3 in two-thirds and stage 4 in one-third of all cases. The wound healing lasted longer in the 71 stoma-presenting patients than in the 392 patients with undeviated defecation (77 vs. 59 days, p = 0.02). The age (regression coefficient b = 0.41, p = 0.02), the ASA classification (b = 16.04, p = 0.001) and the stage of the ulcers (b = 19.65, p = 0.001) were associated with prolonged ulcer treatment in the univariate analysis. The multiple regression analysis revealed that the fecal diversion (b = -18.19, p = 0.03) and the stage of the ulcers (b = 21.62, p = 0.001) were the only predictors of delayed wound healing. CONCLUSION: The presence of a stoma is not related to improved wound healing of ulcers near the anus. On the contrary, stoma patients needed more time until complete wound healing, conceivably related to selection bias. Nonetheless, we currently do not recommend fecal diversion to be the standard concept for decubitus treatment.

This study aimed to assess the outcome of acute and chronic participants with spinal cord injury (SCI) after 12 weeks of bodyweight supported treadmill training (BWSTT) with a hybrid assistive limb exoskeleton (HAL). Acute participants were defined as ≤12 months between SCI and training, chronic participants >12 months between SCI and training. We assessed whether HAL-assisted BWSTT is advantageous for acute and chronic participants and if length of time post injury impacts the outcome of HAL-assisted BWSTT. As the primary outcome, we assessed the time needed for the 10 meter walk test (10MWT). Hundred and twenty-one individuals participated in a 12-week HAL-assisted BWSTT five times a week. We regularly conducted a 10MWT, a 6 minute walk test (6MWT), and assessed the walking index for spinal cord injury (WISCI II) and lower extremity motor score (LEMS) to evaluate the gait performance without the exoskeleton. Distance and time were recorded by the treadmill while the participant was walking with the exoskeleton. All participants benefit from the 12-week HAL-assisted BWSTT. A significant difference between acute and chronic participants' outcomes was found in 6MWT, LEMS, and WISCI II, though not in 10MWT. Although chronic participants improved significantly lesser than acute participants, they did improve their outcome significantly compared to the beginning. Hybrid assistive limb-assisted BWSTT in the rehabilitation of patients with SCI is advantageous for both acute and chronic patients. We could not define a time related cut-off threshold following SCI for effectiveness of HAL-assisted BWSTT.
RESUMEN
OBJECTIVE: In Germany, treatment paths for patients with acute spinal cord injury (SCI) differ considerably depending on intrinsic, disease-specific and extrinsic factors. Which of these factors are associated with improved outcome with fewer subsequent complications and inpatient re-admissions is not clear. The German-wide, patient-centered, web-based ParaReg registry will be implemented to improve the long-term quality of patient care and the planning of treatment paths with increased cost-effectiveness. METHODS: In the 2017-18 conceptualization phase, the data model of the registry was developed in an iterative process of the ParaReg steering committee together with the extended DMGP board and patient representatives. In ParaReg, routine social and medical data as well as internationally established neurological, functional and participation scores will be documented. The assignment of a unique patient ID allows a lifelong, cross-center documentation of inpatient stays in one of the 27 SCI centers organized in the German-speaking Medical Society for SCI (DMGP). The ParaReg data protection concept and patient information/consent are based on the Open Source Registry for Rare Diseases (OSSE) which were extended by GDPR-relevant aspects. RESULTS: In the realization phase, which started in 2019, the information technology infrastructure was implemented according to the clinical ID management module of the Technology and Methods Platform for Networked Medical Research (TMF). In parallel, the legal and ethical prerequisites for registry operation under the patronage of the DMGP were created. Recommendations of the working group data protection of the TMF were integrated into ParaReg's data protection concept. Based on the feedback from the alpha test phase with documentation of the hospitalization data of 40 patients, the ergonomics of the electronic case report forms were improved in particular for data entry on mobile devices. CONCLUSION: After completion of the monocentric alpha test phase, the multicenter data acquisition was started in 5 DMGP-SCI centers. The sustainability of ParaReg is ensured by the structural and financial support of the DMGP after expiry of the funding by the German Federal Ministry of Education and Research (BMBF).

In recent years robotic devices became part of rehabilitation offers for patients suffering from Spinal Cord Injury (SCI) and other diseases. Most scientific publications about such devices focus on functional outcome. The aim of this study was to verify whether an improvement in physiological gait can be demonstrated in addition to the functional parameters after treatment with neurological controlled HAL® Robot Suit. Fifteen subjects with acute (<12 months since injury, n = 5) or chronic (>12 months since injury, n = 10) incomplete paraplegia (AIS B, n = 0/AIS C, n = 2/AIS D, n = 8) or complete paraplegia (AIS A, n = 5) with zones of partial preservation participated. Subjects underwent a body weight supported treadmill training for five times a week over 12 weeks using HAL®. At baseline and at the end of the study a gait analysis was performed and additional functional parameters such as 10-Meter-Walk-Test, Timed-Up-and-Go-Test, 6-Minutes-Walk-Test, and WISCI II score were collected. Results were evaluated for whole group and individually for acute and chronic subgroups. All functional parameters improved. Differences were also found in physiological parameters such as phases of gait cycle and accompanied by significant improvement in all spatiotemporal and gait phase parameters. The presented study shows signs that an improvement in physiological gait can be achieved in addition to improved functional parameters in patients with SCI after completing 12-week training with HAL®.

RESUMEN
STUDY DESIGN: Retrospective, monocentric, observational study in a tertiary health care center. OBJECTIVES: To analyze prehospital and clinical findings, complications, neurological improvement and follow-up in a young person cohort with spinal cord injury (SCI) and tetraplegia according to the American Spinal Injury Association (ASIA) Impairment Scale (AIS) A to D after diving into shallow water. METHODS: Included were all persons younger than 50 years with SCI after head-first diving into shallow water between June 2001 and June 2019. All persons with SCI were divided into complete tetraplegia (AIS A) and incomplete tetraplegia (AIS B, C, and D) to test differences. RESULTS: A total of 59 males (98.7%) and 1 female with a mean age of 27.7 years suffered an SCI. Alcohol use was documented in 25 cases (41.7%). At the time of admission, 33 people (55%) showed a complete tetraplegia (AIS A) and 27 showed an incomplete tetraplegia with 8 AIS B (13.3%), 15 AIS C (25%), and 4 AIS D (6.7%). At the time of discharge, people with initially complete tetraplegia showed a significant improvement from admission to discharge (P ≤ .004). Persons with incomplete tetraplegia were more likely to improve their neurological status compared with complete tetraplegia patients (P ≤ .001). Especially persons with complete tetraplegia suffered from typical SCI-related problems and complications. CONCLUSIONS: People with SCI and tetraplegia at the time admission show neurological improvement in 50% of the cases with an overall better outcome in persons with incomplete tetraplegia. The surgical treatment of SCI within 24 hours seems to be associated with a better neurological outcome and a lower level of tetraplegia. The incidence of SCI caused by diving into shallow water remains stable without a significant change, especially in high-risk groups. More education and prevention programs are necessary to avoid these injuries.
RESUMEN
STUDY DESIGN: Retrospective observational study. OBJECTIVES: To analyze the clinical and radiological outcomes of lower limb fractures following surgical treatment in patients with chronic spinal cord injury (SCI). METHODS: Between January 2003 and December 2015, 102 chronic SCI patients with a lower limb fracture were surgically treated at our hospital. A total of 58 patients met the inclusion criteria and were recruited for final analysis. Patients with 2-stage procedure or incomplete clinical records with lost-to-follow-up were excluded from the study. Patients were divided into 2 groups (group 1= internal fixation; group 2 = external fixation). Primary outcome measures were to identify the number of nonunions via Kaplan-Meier analysis and the time to bone consolidation. The diagnosis of a pseudarthrosis was made after more than 180 days of consolidation time. Considering the Kaplan-Meier analysis, pseudarthrosis was interpreted as treatment failure. Secondary outcome measure was to evaluate the complication rate with special focus on heterotopic ossification. RESULTS: A total of 58 chronic SCI patients with closed bone fractures were included in this study. Fifty-two fractures (88%) were simple and 7 (12%) were complex (type C) fractures according to AO classification. The majority of patients (34 cases, 59%) developed femur fractures followed by 24 tibial fractures (41%). Seventeen patients received an external (29%) and 41 an internal fixation (71%). Bone consolidation was reported in 31 patients (53%) with a mean time interval of bone consolidation after 97 days (range from 45 to 160 days; SD = 30). The reported nonunion (pseudarthrosis) rate was 47%. Comparing the internal group (n = 15 patients) versus the external group (n = 14), we could not find any significant difference (P = .939) concerning the bone consolidation time. The Kaplan-Meier analysis showed a 75% cumulative survivorship at 120 days (internal group) versus 111 days (external group). Most common postoperative complications occurred in the internal fixation group with Wound infections being predominantly observed (10%), followed by heterotopic ossifications (8%). CONCLUSIONS: Our results show that surgical treatment of lower limb fractures in chronic SCI patients is a challenging treatment with a high pseudarthrosis rate in both groups. The complication rate seems to be lower in the patients treated with external fixation. As a clinical recommendation, longer implants should be used for a stable osteosynthesis since SCI patients seem to have a higher load on the osteosynthesis material due to missing sensomotoric feedback.
RESUMEN
STUDY DESIGN: Prospective, monocentric observational study. OBJECTIVE: Investigation of incidence and complication rate of cannula changes in long-term tracheotomized patients suffering spinal cord injury. SETTING: University hospital in Bochum, Germany. METHODS: Prospective data collection of all cannula changes between September 2016 and September 2017. Physicians recorded mechanical complications and techniques to solve them, and/or complications resulting in patient-threatening condition. RESULTS: There were 149 cannula changes during 3191 observation days. Overall, urgent cannula changes occurred 2.1 times per 100 observation days. Within the first 8 weeks after tracheostomy, urgent cannula changes were necessary four times per 100 observation days, and were mandatory less than two times per 100 observation days thereafter. Overall, mechanical complications occurred in 12% of cannula changes, and 8% of cannula changes were accompanied by patient-threatening complications. Accidental decannulation (AD) occurred in 0.97 of 100 observation days. Recannulation after AD was accompanied by 29% of mechanical complications during reinsertion, and 16% led to patient-threatening complications. The major risk factors for mechanical complications were the time lag between cannula change and tracheostomy, and the urgency of the procedure while the thyroid cartilage-jugular distance was significantly associated with patient-threatening complications. CONCLUSION: AD and the requirement for urgent cannula changes are common and often related with mechanical and patient-threatening complications. Even weeks after tracheostomy, caregivers need to be aware of serious events, and therefore provide monitoring, knowledge, and appropriate resources to handle these events.

BACKGROUND: Cancer is a major cause of death in patients with spinal cord injury (SCI). Preventive strategies, such as colonoscopy, deal with higher burdens that may lead to lower quality. AIMS: The primary objective was to evaluate the adenoma detection rate. Secondary objectives were to investigate other quality indicators regarding bowel preparation, sedation, and endoscopy. METHODS: Consecutive SCI patients who had undergone colonoscopy from 2003 to 2014 were assigned to a control group matched for age, gender, and year of procedure and reviewed retrospectively. RESULTS: Bowel preparation lasted longer (3.6 ± 1.5 vs. 1.2 ± 0.6 days, p = 0.001), achieved unsatisfactory cleansing results more often (23.7 vs. 3.6%) and caused more adverse events in 236 SCI compared to 414 control patients. Colonoscopy needed a longer time (36.9 vs. 25.0 min) and remained incomplete more often (24.6 vs. 4.6%), resulting in more re-colonoscopies (14.8 vs. 4.3%). Endoscopy- and sedation-related adverse events were equal. However, neither overall nor size-dependent polyp (30.9 vs. 34.8%), adenoma (21.2 vs. 21.0%), advanced adenoma (6.8 vs. 7.2%), or cancer (1.7 vs. 2.0%) detection rates differed. CONCLUSION: Despite intensified protocols, bowel preparation shows inferior results in SCI patients; colonoscopy needs more effort to succeed but achieves a comparable quality.

Background: The exoskeleton HAL (hybrid assistive limb) has proven to improve walking functions in spinal cord injury and chronic stroke patients when using it for body-weight supported treadmill training (BWSTT). Compared with other robotic devices, it offers the possibility to initiate movements actively. Previous studies on stroke patients did not compare HAL-BWSTT with conventional physiotherapy (CPT). Therefore, we performed a crossover clinical trial comparing CPT and HAL-BWSTT in chronic stroke patients with hemiparesis, the HALESTRO study. Our hypothesis was that HAL-training would have greater effects on walking and posture functions compared to a mixed-approach CPT. Methods: A total of 18 chronic stroke patients participated in this study. Treatment consisted of 30 CPT sessions and of 30 sessions of BWSTT with a double leg type HAL exoskeleton successively in a randomized, crossover study design. Primary outcome parameters were walking time and speed in 10-meter walk test (10MWT), time in timed-up-and-go test (TUG) and distance in 6-min walk test (6MWT). Secondary outcome parameters were the functional ambulatory categories (FAC) and the Berg-Balance Scale (BBS). Data were assessed at baseline, at crossover and at the end of the study, all without using and wearing HAL. Results: Our study demonstrate neither a significant difference in walking parameters nor in functional and balance parameters. When HAL-BWSTT was applied to naïve patients, it led to an improvement in walking parameters and in balance abilities. Pooling all data, we could show a significant effect in 10MWT, 6MWT, FAC and BBS, both therapies sequentially applied over 12 weeks. Thereby, FAC improve from dependent to independent category (3 to 4). One patient dropped out of the study due to intensive fatigue after each training session. Conclusion: HAL-BWSTT and mixed-approach CPT were effective therapies in chronic stroke patients. However, compared with CPT, HAL training with 30 sessions over 6 weeks was not more effective. The combination of both therapies led to an improvement of walking and balance functions. Robotic rehabilitation of walking disorders alone still lacks the proof of superiority in chronic stroke. Robotic treatment therapies and classical CPT rehabilitation concepts should be applied in an individualized therapy program.
