[Positive effects of training curriculum using the example of the interdisciplinary intensive care unit]. / Positive Effekte eines Einarbeitungs- und Weiterbildungscurriculums am Beispiel der interdisziplinären Intensivstation.

The training of new medical colleagues in hospitals is due to various aspects such as for instance staff shortages and time pressure often very challenging for everyone involved. Using the example of the interdisciplinary intensive care unit, the positive effects of a structured training curriculum have been scientifically proven in regular employee surveys. There was a statistically significant increase in satisfaction in the quality of induction (p < 0.0001), quality of training (p < 0.0001),  preparation for night shifts in the intensive care unit (p < 0.0001) and an improvement in general satisfaction in the clinic (p < 0.003) can also be shown. For these reasons, such curriculum contributes to increasing the quality of care and patient safety as well as the safety of medical staff in the medical work.

Serial ankle casts for patients with idiopathic toe walking: effects on functional gait parameters.

PURPOSE: The aim of the present study was to investigate the functional effects on gait parameters of serial ankle casts for patients with idiopathic toe walking (ITW), in comparison with an unremarkable control group. METHODS: A prospective trial with a pre-test-post-test control group design included ten patients with ITW and ten healthy matched children. Children with ITW underwent serial casting to stretch the plantar flexors, with two 14-day periods with walking plaster casts set at the maximum available ankle dorsiflexion. Both groups were assessed clinically and using a functional gait analysis before and after serial casting, as well as at a six-month follow-up visit. RESULTS: The normalized plantar heel force increased from 5% pre-interventionally to 79% at the follow-up. The upper ankle-joint angle and the base angle also demonstrated significant changes. Normalized compound action potentials of the medial heads of the gastrocnemius were reduced by 70%. None of these parameters demonstrated any significant differences at the follow-up examination in comparison with the healthy control group. Variations in the displacement of the knee joint on the sagittal plane and of the center of gravity in the transverse plane did not show any significant differences in comparison with the control group. CONCLUSION: The reduction of muscle tone and lengthening of the ankle plantar flexors led to persistent increased active ankle dorsiflexion with significant long-term improvement of functional kinematic parameters. No significant difference in the gait analysis was found between the ITW group and healthy children six months after treatment.Level of Evidence: Level II - Therapeutic.

[Weaning from dialysis after acute kidney injury in chronically critically ill]. / Renale Rekompensation nach akuter Nierenschädigung bei chronisch kritisch kranken Patienten.

This study describes the course of renal recovery after dialysis in a specific population of chronically critically ill patients with a history of prolonged and complicated treatment in an intensive care unit. This study shows that, in a specialized center, patients can be successfully weaned from dialysis even months after acute kidney injury (AKI). Of the patients who could be recompensated (33%), approximately 20% achieved renal recovery more than 3 months after the start of dialysis. The duration of renal recovery after AKI did not differ between those patients with pre-existing chronic kidney disease (CKD) and those without. The reason for dialysis treatment such as sepsis, surgery, resuscitation, as well as the risk factors (e. g., diabetes mellitus, arterial hypertension, arteriosclerosis) did not reveal a difference in weaning in a hazard analysis. As a potential risk factor, only age significantly influenced weaning from dialysis in the multivariate hazard model.

Is body-weight-supported treadmill training or robotic-assisted gait training superior to overground gait training and other forms of physiotherapy in people with spinal cord injury? A systematic review.

STUDY DESIGN: Systematic review about randomised trials comparing different training strategies to improve gait in people with spinal cord injuries (SCI). OBJECTIVES: The aim of this systematic review was to compare the effectiveness of body-weight-supported treadmill training (BWSTT) and robotic-assisted gait training with overground gait training and other forms of physiotherapy in people with traumatic SCI. SETTING: Systematic review conducted by researchers from Germany and Australia. METHODS: An extensive search was conducted for randomised controlled trials involving people with traumatic SCI that compared either BWSTT or robotic-assisted gait training with overground gait training and other forms of physiotherapy. The two outcomes of interest were walking speed (m s-1) and walking distance (m). BWSTT and robotic-assisted gait training were analysed separately, and data were pooled across trials to derive mean between-group differences using a random-effects model. RESULTS: Thirteen randomised controlled trials involving 586 people were identified. Ten trials involving 462 participants compared BWSTT to overground gait training and other forms of physiotherapy, but only nine trials provided useable data. The pooled mean (95% confidence interval (CI)) between-group differences for walking speed and walking distance were -0.03 m s-1 (-0.10 to 0.04) and -7 m (-45 to 31), respectively, favouring overground gait training. Five trials involving 344 participants compared robotic-assisted gait training to overground gait training and other forms of physiotherapy but only three provided useable data. The pooled mean (95% CI) between-group differences for walking speed and walking distance were -0.04 m s-1 (95% CI -0.21 to 0.13) and -6 m (95% CI -86 to 74), respectively, favouring overground gait training. CONCLUSIONS: BWSTT and robotic-assisted gait training do not increase walking speed more than overground gait training and other forms of physiotherapy do, but their effects on walking distance are not clear.

Outcome of neurological early rehabilitation patients carrying multi-drug resistant bacteria: results from a German multi-center study.

BACKGROUND: Colonization or infection with multi-drug resistant (MDR) bacteria is considered detrimental to the outcome of neurological and neurosurgical early rehabilitation patients. METHODS: In a German multi-center study, 754 neurological early rehabilitation patients were enrolled and and reviewed in respect to MDR status, length of stay (LOS) and the following outcome variables: Barthel Index (BI), Early Rehabilitation Index (ERI), Glasgow Outcome Score Extended (GOSE), Coma Remission Scale (CRS), Functional Ambulation Categories (FAC). RESULTS: The mean age of the study population was 68.0 ± 14.8 years. Upon admission, the following prevalence for MDRs was observed: MRSA (methicillin resistant staphylococcus aureus) 7.0% (53/754), ESBL- (extended spectrum beta-lactamase) producing bacteria strains 12.6% (95/754), VRE (vancomycin resistant enterococci) 2.8% (21/754). Patients colonized or infected with MDR bacteria (MDR+) were significantly more frequently diagnosed with a critical illness polyneuropathy - CIP - than non-colonized (MDR-) patients: 29.0% vs. 14.8%. In addition, they were more frequently mechanically ventilated (MDR+: 55/138, 39.9%; MDR- 137/616, 22.2%). MDR+ patients were referred to rehabilitation earlier, had a longer LOS in early rehabilitation, lower BI on admission and at discharge, lower ERI on admission and lower CRS at discharge than MDR- patients. There was a highly significant correlation of the BI upon admission with the BI at discharge (rs = 0.492, p < 0.001). GOSE at discharge differed significantly between both groups (χ 2-test, p < 0.01). Perhaps of greatest importance, mortality among MDR+ was higher in comparison to MDR- (18.1% vs. 7.6%). CONCLUSIONS: The outcome of neurological early rehabilitation patients colonized or infected with MDR bacteria including MRSA or ESBL producing strains is significantly poorer than by non-colonized patients. There is some evidence that the poor outcome could be related to the higher morbidity and lower functional status upon admission.

Criterion validity and sensitivity to change of the Early Rehabilitation Index (ERI): results from a German multi-center study.

BACKGROUND: Evaluation of functional status is difficult in neurological and neurosurgical early rehabilitation patients. The Early Rehabilitation Index (ERI) was introduced in Germany over 20 years ago, but since then validation studies are lacking. The ERI (range -325 to 0 points) includes highly relevant items including the necessity of intermittent mechanical ventilation or tracheostomy. METHODS: The present paper analyzed data from a German multi-center study, enrolling 754 neurological early rehabilitation patients. Together with ERI, Barthel Index (BI), Glasgow Coma Scale (GCS), Glasgow Outcome Score Extended, Coma Remission Scale (CRS), Functional Ambulation Categories and length of stay were obtained. RESULTS: ERI showed significant improvements from admission to discharge (p < 0.001). In addition, there were significant correlations of the ERI upon admission and at discharge with BI, CRS and GCS. CONCLUSIONS: Evaluation of our study data suggest that the ERI may be used as a valid assessment instrument for neurological and neurosurgical early rehabilitation patients.

[Course of rehabilitation in early neurological/neurosurgical rehabilitation. Results of a 2014 multi-center evaluation in Germany]. / Rehabilitationsverlauf von Patienten in der neurologisch-neurochirurgischen Frührehabilitation.

BACKGROUND: In Germany, neurological-neurosurgical early rehabilitation is well established in the treatment of severe neurological diseases. To develop quality standards, knowledge of the current rehabilitation course is required. PATIENTS AND METHODS: A retrospective analysis was performed on the course of rehabilitation from patients in an early neurological/neurosurgical rehabilitation program in 16 centers from 10 German states. The odds for a good or poor outcome were investigated using a multivariate logistic regression model. RESULTS: Seven hundred and fifty-four patients were included in the study. The average age of the patients was 68 ± 15 years. Of the patients studied, 26 % were on mechanical ventilation commencing their neurological rehabilitation. The average duration of stay was 56 ± 51 days. Weaning rate from mechanical ventilation was 65 % and the rate of weaning from tracheal cannula was 54 %. Mean improvement in the Barthel Index of 17 points, significant reduction of dysphagia (from 62 to 30 %) and depended walking (from 99 to 82 %), and the achievement of phase C (the next stage of rehabilitation) in 38 % can still be counted as signs of successful rehabilitation. During their course of stay, near 10 % of the patients died. Of these, 67 % received solely palliative care. In the multivariate logistic models, the absence of the factor "necessity for mechanical ventilation on admission" (odds ratio 0.61; 95 % confidence interval (CI): 0.42 … 0.89) increased the chance for good outcome and the presence of this factor the risk of dying with an odds ratio of 8.07 (95 % CI: 4.54-14.34). DISCUSSION: In spite of the severity of neurological deficits, significant functional progress has been made. These results could be interpret as positive proof of the efficacy of neurological/neurosurgical early rehabilitation programs.

Physical rehabilitation for critical illness myopathy and neuropathy: an abridged version of Cochrane Systematic Review.

Intensive care unit (ICU) acquired or generalised weakness due to critical illness myopathy (CIM) and polyneuropathy (CIP) are major causes of chronically impaired motor function that can affect activities of daily living and quality of life. Physical rehabilitation of those affected might help to improve activities of daily living. Our primary objective was to assess the effects of physical rehabilitation therapies and interventions for people with CIP and CIM in improving activities of daily living such as walking, bathing, dressing and eating. Secondary objectives were to assess effects on muscle strength and quality of life, and to assess adverse effects of physical rehabilitation. On 16 July 2014 we searched the Cochrane Neuromuscular Disease Group Specialized Register and on 14 July 2014 we searched CENTRAL, MEDLINE, EMBASE and CINAHL Plus. In July 2014, we searched the Physiotherapy Evidence Database (PEDro) and three trials registries for ongoing trials and further data about included studies with no language restrictions. We also handsearched relevant conference proceedings and screened reference lists to identify further trials. We planned to include randomised controlled trials (RCTs), quasi-RCTs and randomised controlled cross-over trials of any rehabilitation intervention in people with acquired weakness syndrome due to CIP/CIM. We would have extracted data, assessed the risk of bias and classified the quality of evidence for outcomes in duplicate, according to the standard procedures of The Cochrane Collaboration. Outcome data collection would have been for activities of daily living (for example, mobility, walking, transfers and self care). Secondary outcomes included muscle strength, quality of life and adverse events. The search strategy retrieved 3587 references. After examination of titles and abstracts, we retrieved the full text of 24 potentially relevant studies. None of these studies met the inclusion criteria of our review. No data were suitable to be included in a meta-analysis. There are no published RCTs or quasi-RCTs that examine whether physical rehabilitation interventions improve activities of daily living for people with CIP and CIM. Large RCTs, which are feasible, need to be conducted to explore the role of physical rehabilitation interventions for people with CIP and CIM. This paper is based on a Cochrane Review published in in the Cochrane Database of Systematic Reviews (CDSR) 2015, Issue 3, DOI: 10.1002/14651858.CD010942.pub2. (see www.thecochranelibrary.com for information). Cochrane Reviews are regularly updated as new evidence emerges and in response to feedback, and the CDSR should be consulted for the most recent version of the review.

Evidence of end-effector based gait machines in gait rehabilitation after CNS lesion.

BACKGROUND: A task-specific repetitive approach in gait rehabilitation after CNS lesion is well accepted nowadays. To ease the therapists' and patients' physical effort, the past two decades have seen the introduction of gait machines to intensify the amount of gait practice. Two principles have emerged, an exoskeleton- and an endeffector-based approach. Both systems share the harness and the body weight support. With the end-effector-based devices, the patients' feet are positioned on two foot plates, whose movements simulate stance and swing phase. OBJECTIVE: This article provides an overview on the end-effector based machine's effectiveness regarding the restoration of gait. METHODS: For the electromechanical gait trainer GT I, a meta analysis identified nine controlled trials (RCT) in stroke subjects (n = 568) and were analyzed to detect differences between end-effector-based locomotion + physiotherapy and physiotherapy alone. RESULTS: Patients practising with the machine effected in a superior gait ability (210 out of 319 patients, 65.8% vs. 96 out of 249 patients, 38.6%, respectively, Z = 2.29, p = 0.020), due to a larger training intensity. Only single RCTs have been reported for other devices and etiologies. CONCLUSION: The introduction of end-effector based gait machines has opened a new succesful chapter in gait rehabilitation after CNS lesion.

[Application of a sponaneous ventilation protocol. Experiences from a weaning center for neurological diseases]. / Anwendung eines standardisierten Spontanatmungsprotokolls. Erfahrungen in einem Weaning-Zentrum mit neurologischem Schwerpunkt.

OBJECTIVE: The aim of this study was to investigate a novel standardized protocol in this neurological weaning unit in order to optimize the weaning process for patients subjected to prolonged mechanical ventilation. Of primary interest were the frequency of and reasons for deviating from the protocol as well as risk factors for weaning failure and mortality. PATIENTS AND METHODS: All patients admitted to the weaning unit were enrolled in this prospective observational study. The weaning protocol consisted of 22 discrete weaning steps. An individual weaning approach was only begun if the standardized protocol failed. Variables for risk analysis included age, body mass index, APACHE II score, reason for initiating mechanical ventilation, total duration of inpatient stay before admission to the weaning unit, extent of mechanical ventilation period before admission, chronic pulmonary diseases and dialysis. RESULTS: Between October 2007 and December 2008 a total of 644 consecutively admitted patients were enrolled in the study. The mean age was 67.6 ± 12.3 years, the mean inpatient stay before admission was 45.8 ± 34.9 days and the mean duration of mechanical ventilation before admission to the unit was 38.1 ± 28.7 days. The mean APACHE II score was 19.0 ± 7.2, 68 % of the patients were male, 98.6 % had a tracheotomy tube, 30.9 % had a history of chronic pulmonary disease and 13.7 % required dialysis. Reasons for initiating ventilation were cerebral 33.1 %, pulmonary 28.7 %, cardiovascular 31.5 %, neuropathic 2.8 %, myopathic 0.9 %, spinal cord injuries 1.9 % and 1.1 % were unclear. Weaning was successful in 77.3 % (498 patients) of all cases with a mean duration of 22.0 ± 33.9 days. Of those successfully weaned, a total of 85.9 % (n = 428) were weaned according to the standard protocol. The weaning process was also shorter (20.8 ± 35.6 versus 29.0 ± 19.9 days) for those patients weaned according to the protocol compared to those patients where the protocol failed. Protocol failure was normally due to complications during the weaning process. Among the patients where the protocol failed, chronic pulmonary disease (41.4 versus 28.3 %; p < 0.02), a longer duration of ventilation (42.3 ± 22.8 versus 35.9 ± 25.3 days; p < 0.01) and a longer in-hospital stay (52.7 ± 41.4 versus 42.4 ± 30.1 days; p < 0.01) prior to admission were significantly more common. A total of 23.0 % (n = 148) of the patients died and 9.8 % (n = 63) of the patients were discharged into a home care ventilation program. Chronic pulmonary disease and the duration of inpatient stay prior to admission were predictors of weaning failure. The APACHE II score, age and acute renal failure with concomitant need for dialysis were the factors best predicting mortality. CONCLUSIONS: The majority of patients receiving prolonged mechanical ventilation can be successfully weaned using a standardized protocol. Failures of standardized weaning per protocol occurred most often in patients with chronic pulmonary disease and following longer inpatient stay. These patients also had a higher risk of final weaning failure.

[Critical illness polyneuropathy und polymyopathy. How certain is the clinical diagnosis in patients with weaning failure?]. / Critical-illness-Polyneuropathie und -Polymyopathie. Wie sicher ist die klinische Diagnose bei Patienten mit Weaning-Versagen?

A frequent cause of weaning failure and the resultant long-term artificial ventilation is the generalized weakness syndrome in the sense of critical illness polyneuropathy or polymyopathy. However, hardly any information is presently available regarding the necessary intensity of the diagnostic workup for reaching or excluding a diagnosis with certainty in the neurological examination or regarding the additional diagnostic value of electrophysiological studies in patients receiving long-term acute care suspected of having critical illness polyneuropathy and polymyopathy. Therefore, the goal of this investigation was to address these questions. A total of 280 patients with complicated weaning were included in the study. All patients underwent clinical examination by a specialist in neurology and electrophysiological workup performed by another specialist. Among the patients studied, the greatest possible certainty of the diagnosis (positive predictive value) of the clinical examination was 97.9% [95% confidence interval (CI) 69.4-99.9] and the best certainty of excluding the diagnosis (negative predictive value) was 88.9% (95% CI 82.7-93.0). Thus, in difficult-to-wean patients who were considered to probably have the diagnosis of critical illness polyneuropathy or polymyopathy as assessed by a specialist, little additional information is gained from an electrophysiological study, which is hence dispensable in these cases.

[Long-term course of patients in neurological rehabilitation Phase B. Results of the 6-year follow-up in a multicenter study]. / Langzeitverlauf von Patienten der neurologischen Rehabilitation Phase B. Ergebnisse der 6-Jahres-Nachuntersuchung einer Multicenterstudie.

BACKGROUND: After conclusion of emergency care for severe neurological diseases patients in Germany are admitted at an early stage to so-called Phase B rehabilitation. No studies have been carried out on the long-term course of these patients. PATIENTS AND METHODS: In a prospective study in 2002 patients in Phase B from 9 centers were included and follow-up investigations were carried out after 5 and 6 years. Assessment instruments used were the Barthel index, the Rankin scale and the EQ-5D. Factors for the risk of a poor outcome and the chances for a good outcome were evaluated using multivariate logistic regression. RESULTS: A total of 1,280 patients were included in the study. A high age increased the risk of dying with a hazard quotient (HQ) of 1.05 (95% CI: 1.04-1.06) and high point counts in the coma remission scale (HQ 0.93; 95% CI: 0.92-0.96) and Barthel index (HQ 0.97; 95% CI: 0.97-0.98) on discharge reduced the risk of dying after 5 years. The factors swallowing impairment (OR 3.1; 95% CI: 1.7-5.5) and obligatory surveillance at the end of rehabilitation (OR 3.2; 95% CI: 1.2-8.6) increased the risk of a poor result in the Rankin scale 2-4 and the factors communication disorder (OR 5.0; 95% CI: 2.0-12.8) and PEG (percutaneous endoscopic gastrostomy) (OR 19.7; 95% CI: 2.7-144.4) on discharge increased the risk of a reduced health-related quality of life (defined as EQ-5D VAS <70) after 6 years. CONCLUSIONS: If support for bodily functions can be successfully reduced during Phase B rehabilitation, the patients will have a good outcome with respect to 5-year survival. If this is not successful the outcome is unfavorable with respect to survival and with respect to achieving self-sufficiency and health-related quality of life after 6 years.

Mechanical arm trainer for the treatment of the severely affected arm after a stroke: a single-blinded randomized trial in two centers.

OBJECTIVE: To test whether training with a new mechanical arm trainer leads to better outcomes than electrical stimulation of the paretic wrist extensors in subacute stroke patients with severe upper limb paresis. Electrical stimulation is a standard and reimbursable form of therapy in Germany. DESIGN: Randomized controlled trial of 54 inpatients enrolled 4-8 wks from stroke onset, mean upper-extremity subsection of Fugl-Meyer assessment (0-66) at admission less than 18. In addition to standard care, all patients practiced 20-30 mins arm trainer or electrical stimulation every workday for 6 wks, totaling 30 sessions. Primary outcome was the Fugl-Meyer assessment, secondary outcomes were the Box and Block test, the Medical Research Council and the modified Ashworth scale, blindly assessed at enrollment, after 6 wks, and at 3-mo follow-up. RESULTS: Both groups were homogeneous at study onset. Shoulder pain occurred in two arm trainer patients. The primary Fugl-Meyer assessment outcome improved for both groups over time (P < 0.001), but this improvement did not differ between groups. The initial (terminal) mean Fugl-Meyer assessment scores were 8.8 +/- 4.8 (19.2 +/- 14.5) for the arm trainer and 8.6 +/- 3.5 (13.6 +/- 7.9) for the electrical stimulation group. No patient could transport a block initially, but at completion significantly more arm trainer patients were able to transport at least three blocks (five vs. zero, P = 0.023). No significant differences were observed between the groups on the secondary Box and Block outcome at follow-up (eight vs. four patients). All Box and Block responders had an initial Fugl-Meyer assessment > or =10. CONCLUSIONS: Arm trainer training did not lead to a superior primary outcome over electrical stimulation training. However, "good performers" on the secondary outcome seemed to benefit more from the arm trainer training.

Locomotor training for walking after spinal cord injury.

BACKGROUND: Locomotor training for walking is used in rehabilitation after spinal cord injury (SCI) and might help to improve walking. OBJECTIVES: To assess the effects of locomotor training on improvement in walking for people with traumatic SCI. SEARCH STRATEGY: We searched the Cochrane Injuries Group Specialised Register (last searched June 2007); the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2007, Issue 2); MEDLINE (1966 to June 2007); EMBASE (1980 to June 2007); National Research Register (2007, Issue 2); CINAHL (1982 to June 2007); AMED (Allied and Complementary Medicine Database) (1985 to June 2007); SPORTDiscus (1949 to June 2007); PEDro (the Physiotherapy Evidence database) (searched June 2007); COMPENDEX (engineering databases) (1972 to June 2007); INSPEC (1969 to June 2007); and the National Research Register, Zetoc, and Current Controlled Trials research and trials registers. We also handsearched relevant conference proceedings, checked reference lists and contacted study authors in an effort to identify published, unpublished and ongoing trials. SELECTION CRITERIA: We included randomised controlled trials (RCT) that compared locomotor training to any other exercise provided with the goal of improving walking function after SCI or to a no-treatment control group. DATA COLLECTION AND ANALYSIS: Two review authors independently selected trials for inclusion, assessed trial quality and extracted the data. The primary outcomes were the speed of walking and walking capacity at follow up. MAIN RESULTS: Four RCTs involving 222 patients were included in this review. Overall, the results were inconclusive. There was no statistically significant effect of locomotor training on walking function after SCI comparing bodyweight supported treadmill training with or without functional electrical stimulation or robotic-assisted locomotor training. AUTHORS' CONCLUSIONS: There is insufficient evidence from RCTs to conclude that any one locomotor training strategy improves walking function more than another for people with SCI. Research in the form of large RCTs is needed to address specific questions about the type of locomotor training which might be most effective in improving walking function of people with SCI.

Electromechanical-assisted training for walking after stroke.

BACKGROUND: Electromechanical and robotic-assisted gait training devices are used in rehabilitation and might help to improve walking after stroke. OBJECTIVES: To investigate the effect of automated electromechanical and robotic-assisted gait training devices for improving walking after stroke. SEARCH STRATEGY: We searched the Cochrane Stroke Group Trials Register (last searched September 2006), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, Issue 3, 2006), MEDLINE (1966 to September 2006), EMBASE (1980 to September 2006), CINAHL (1982 to October 2006), AMED (1985 to October 2006), SPORTDiscus (1949 to August 2006), the Physiotherapy Evidence Database (PEDro, searched September 2006) and the engineering databases COMPENDEX (1972 to October 2006) and INSPEC (1969 to October 2006). We handsearched relevant conference proceedings, searched trials and research registers, checked reference lists and contacted authors in an effort to identify further published, unpublished and ongoing trials. SELECTION CRITERIA: We included studies using random assignment. DATA COLLECTION AND ANALYSIS: Two review authors independently selected trials for inclusion, assessed trial quality and extracted the data. The primary outcome was the proportion of patients walking independently (without assistance or help of a person) at follow up. MAIN RESULTS: Eight trials (414 participants) were included in this review. Electromechanical-assisted gait training in combination with physiotherapy increased the odds of becoming independent in walking (odds ratio (OR) 3.06, 95% confidence interval (CI) 1.85 to 5.06; P < 0.001), and increased walking capacity (mean difference (MD) = 34 metres walked in six minutes, 95% CI 8 to 60; P = 0.010), but did not increase walking velocity significantly (MD = 0.08 m/sec, 95% CI -0.01 to 0.17; P = 0.08). However, the results must be interpreted with caution because (1) variations between the trials were found with respect to duration and frequency of treatment and differences in ambulatory status of patients, and (2) some trials tested electromechanical devices in combination with functional electrical stimulation. AUTHORS' CONCLUSIONS: Patients who receive electromechanical-assisted gait training in combination with physiotherapy after stroke are more likely to achieve independent walking than patients receiving gait training without these devices. However, further research should address specific questions, for example, which frequency or duration of electromechanical-assisted gait training might be most effective and at what time after stroke, and follow-up studies are needed to find out how long the benefit lasts. Future research should include estimates of the costs (or savings) due to electromechanical gait training.

Repetitive locomotor training and physiotherapy improve walking and basic activities of daily living after stroke: a single-blind, randomized multicentre trial (DEutsche GAngtrainerStudie, DEGAS).

OBJECTIVE: To evaluate the effect of repetitive locomotor training on an electromechanical gait trainer plus physiotherapy in subacute stroke patients. DESIGN: Randomized controlled trial. SETTING: Four German neurological rehabilitation centres. SUBJECTS: One hundred and fifty-five non-ambulatory patients (first-time stroke <60 days). INTERVENTION: Group A received 20 min locomotor training and 25 min physiotherapy; group B had 45 min physiotherapy every week day for four weeks. MAIN OUTCOME MEASURES: Primary variables were gait ability (Functional Ambulation Category, 0-5) and the Barthel Index (0-100), blindly assessed at study onset, end, and six months later for follow-up. Responders to the therapy had to become ambulatory (Functional Ambulation Category 4 or 5) or reach a Barthel Index of > or = 75. Secondary variables were walking velocity, endurance, mobility and leg power. RESULTS: The intention-to-treat analysis revealed that significantly greater number of patients in group A could walk independently: 41 of 77 versus 17 of 78 in group B (P B < 0.0001) at treatment end. Also, significantly more group A patients had reached a Barthel Index > or = 75: 44 of 77 versus 21 of 78 (P B < 0.0001). At six-month follow-up, the superior gait ability in group A persisted (54 of 77 versus 28 of 78, P B < 0.0001), while the Barthel Index responder rate did not differ. For all secondary variables, group A patients had improved significantly more (P B < 0.0001) during the treatment period, but not during follow-up. CONCLUSIONS: Intensive locomotor training plus physiotherapy resulted in a significantly better gait ability and daily living competence in subacute stroke patients compared with physiotherapy alone.

Computerized arm training improves the motor control of the severely affected arm after stroke: a single-blinded randomized trial in two centers.

BACKGROUND AND PURPOSE: To compare a computerized arm trainer (AT), allowing repetitive practice of passive and active bilateral forearm and wrist movement cycle, and electromyography-initiated electrical stimulation (ES) of the paretic wrist extensor in severely affected subacute stroke patients. METHOD: A total of 44 patients, 4 to 8 weeks after stroke causing severe arm paresis (Fugl-Meyer Motor Score [FM, 0 to 66] <18), were randomly assigned to either AT or ES. All patients practiced 20 minutes every workday for 6 weeks. AT patients performed 800 repetitions per session with the robot and ES patients performed 60 to 80 wrist extensions per session. The primary outcome measure was the blindly assessed FM (0 to 66), and the secondary measures were the upper limb muscle power (Medical Research Council [MRC] sum, 0 to 45) and muscle tone (Ashworth score sum, 0 to 25), assessed at the beginning and end of treatment and at 3-month follow-up. RESULTS: The AT group had a higher Barthel Index score at baseline, but the groups were otherwise homogenous. As expected, FM and MRC sum scores improved overtime in both groups but significantly more in the robot AT group. The initial Barthel Index score had no influence. In the robot AT group, FM score was 15 points higher at study end and 13 points higher at 3-month follow-up than the control ES group. MRC sum score was 15 points higher at study end and at 3-month follow-up compared with the control ES group. Muscle tone remained unchanged, and no side effects occurred. CONCLUSIONS: The computerized active arm training produced a superior improvement in upper limb motor control and power compared with ES in severely affected stroke patients. This is probably attributable to the greater number of repetitions and the bilateral approach.
