Development of a Multidimensional, Multigroup Measure of Self-Care for Inpatient Rehabilitation

OBJECTIVE

To develop and evaluate a measure of clinician-observed and patient-performed self-care function for use during inpatient rehabilitation.

DESIGN

Retrospective analysis of self-care assessments collected by therapists using confirmatory factor analysis (CFA) followed by multidimensional item response theory (MIRT).

SETTING

Freestanding inpatient rehabilitation hospital in the Midwestern United States.

PARTICIPANTS

Inpatients (N=7719) with stroke, traumatic brain injury, spinal cord injury, neurologic disorders, and musculoskeletal conditions.

INTERVENTIONS

Not applicable MAIN OUTCOME MEASURES: A total of 19 clinician-selected self-care measures including the FIM and patient-performed, clinician-rated measures of balance, upper extremity function, strength, changing body position, and swallowing. Clinicians completed assessments on admission and at least 1 interim assessment.

RESULTS

CFA was completed for 3 patient groups defined by their highest level of balance (sitting, standing, walking). We reduced the number of items by 47.5% while maintaining acceptable internal consistency; unidimensionality within each item set required development of testlets. A recursive analysis defined a self-care measure with sensitivity (Cohen d_max-min =1.13; Cohen d_last-first.=0.91) greater than the FIM self-care items (d_max-min.=0.94; d_last-first .=0.83). The CFA models provided good to acceptable fit (root mean square error of approximations 0.03-0.06). Most patients with admission FIM self-care ratings of total assistance (88%, 297 of 338) made improvements on the MIRT self-care measure that were undetected by the FIM; the FIM detected no change for 26% of these patients (78 of 297). The remaining 74% (219 of 297) improved on the MIRT-based measure an average of 14 days earlier than was detected by the FIM.

CONCLUSIONS

This MIRT self-care measure possesses measurement properties that are superior to the FIM, particularly for patients near its floor or ceiling. Methods assure accommodation for multidimensionality and high levels of sensitivity. This self-care measure has the potential to improve monitoring of self-care and manage therapy effectively during inpatient rehabilitation.

Relationship between Use of Rehabilitation Resources and ICU Readmission and ER Visits in ICU Survivors: the Korean ICU National Data Study 2008-2015

BACKGROUND

Despite the increasing importance of rehabilitation for critically ill patients, there is little information regarding how rehabilitation therapy is utilized in clinical practice. Our objectives were to evaluate the implementation rate of rehabilitation therapy in the intensive care unit (ICU) survivors and to investigate the effects of rehabilitation therapy on outcomes.

METHODS

A retrospective nationwide cohort study with including > 18 years of ages admitted to ICU between January 2008 and May 2015 (n = 1,465,776). The analyzed outcomes were readmission to ICU readmission and emergency room (ER) visit.

RESULTS

During the study period, 249,918 (17.1%) patients received rehabilitation therapy. The percentage of patients receiving any rehabilitation therapy increased annually from 14% in 2008 to 20% in 2014, and the percentages for each type of therapy also increased over time. The most common type of rehabilitation was physical therapy (91.9%), followed by neuromuscular electrical stimulation (29.6%), occupational (28.6%), respiratory, (11.6%) and swallowing (10.3%) therapies. After adjusting for confounding variables, the risk of 30-day ICU readmission was lower in patients who received rehabilitation therapy than in those who did not (P < 0.001; hazard ratio [HR], 0.70; 95% confidence interval [CI], 0.65-0.75). And, the risk of 30-day ER visit was also lower in patients who received rehabilitation therapy (P < 0.001; HR, 0.83; 95% CI, 0.77-0.88).

CONCLUSION

In this nationwide cohort study in Korea, only 17% of all ICU patients received rehabilitation therapy. However, rehabilitation is associated with a significant reduction in the risk of 30-day ICU readmission and ER visit.

Cross-Disciplinary Medical Advances with Neuroengineering: Challenges Spur Development of Unique Rehabilitative and Therapeutic Interventions

Neuroengineering brings tools and techniques from the engineering fields into neuroscience to create new approaches for investigating the central nervous system (CNS). This fusion of disciplines is advancing our knowledge of how the CNS works and how we can enhance our natural cognitive and emotional function and restore neurological functions that are compromised by disease or injury.

[NEW OPPORTUNITIES IN NEURO-REHABILITATION: ROBOT MEDIATED THERAPY IN CONDITONS POST CENTRAL NERVOUS SYSTEM IMPAIRMENTS]

Decreasing the often-seen multiple disabilities as a consequence of central nervous system impairments requires broadening of the tools of rehabilitation. A promising opportunity for this purpose is the application of physiotherapy robots. The development of such devices goes back a quarter of century. Nowadays several robots are commercially available both for supporting upper and lower limb therapy. The aim is never to replace the therapists, but rather to support and supplement their work. It is worthwhile applying these devices for goal-oriented exercises in high repetition, which one physically fatiguing for the therapist or for the correction of functional movement by various strategies. Robot mediated therapy is also useful for motivation of the patient and making the rehabilitation programme more versatile. Robots can be used for assessment of the neuromotor status as well. Several clinical studies have been executed in this field, all over the world. Meta-analyses based on randomized, controlled trials show that supplementing the traditional physiotherapy with a robot-mediated component presents advantage for the patients. Further studies are necessary to clarify which modality and intensity of the exercises, in which group of patients, in which stage lead to the expected outcome.

[Robot-assisted and computer-based neurorehabilitation for children: the story behind]

Impairments of the central motor system can either be congenital (e. g. cerebral palsy) or acquired (e. g. traumatic brain injury, stroke). These lesions are the most frequent morbidities necessitating neuro-rehabilitative measures in childhood. Robot-assisted rehabilitation in combination with virtual reality can complement conventional therapies and provide a task-specific training, with a high number of repetitions over a prolonged time period. The advantage of virtual reality is that it can provide a real time feedback about the patient's performance. Furthermore, challenging virtual scenarios especially motivate young patients to continue with otherwise monotonous exercises. Preliminary findings indicate that robot-assisted training in children with central motor impairment could be beneficial, but conclusive evidence about its efficacy is still missing.

[The influence of the pearl baths on the dynamics of cerebral circulation in the children presenting with the consequences of perinatal lesions in the central nervous system]

The present article is concerned with the problem of rehabilitation of the children at the age from 6 to 12 months presenting with perinatal lesions in the central nervous system (CNS) and the role of cerebral hemodynamics in the development of this disease. The results of dynamic clinical and laboratory examination of the children presenting with the consequences of perinatal lesions in the central nervous system are presented with special reference to the influence of the pearl baths on the dynamics of cerebral circulation. The study involving 65 patients showed that the inclusion of bubble bath sin the combined rehabilitative treatment of the children with this condition helps to optimize parameters of the disturbed cerebral blood flow. The positive influence of bubble bath son the dynamics of clinical symptoms and the state of the cardiovascular system has been demonstrated.

Five years later: achieving professional effectiveness to move neurorehabilitation forward

The AOTA Centennial Vision outlined in 2007 challenged the occupational therapy profession to become a "powerful, widely recognized, science-driven, and evidence-based" profession that could adapt to changing societal and cultural needs and flourish well into the future. That challenge can be met by simply being effective at what we do; this will increase our value and validate our worth. Neurorehabilitation in occupational therapy can also thrive if we verify that the interventions we use and the strategies we implement are grounded in evidence. Professional effectiveness will emerge by (1) increasing the dissemination of research that supports the methods we use and informs others of the successful patient outcomes we achieve and (2) expanding development and validation of instruments that quantitatively and qualitatively measure functional outcomes. Occupational therapists can individually develop professional effectiveness by fostering greater academic-clinical alliances, objectifying evaluation and intervention methods, and preparing future practitioners appropriately for evidence-driven practice.

[The early comprehensive rehabilitation of the children with perinatal pathology of the craniovertebral region and cerebrospinal neurological symptoms]

This paper is designed to report the results of a clinical study of the children presenting with neurologic pathology for the detection of the most common concomitant craniovertebral disorders. In addition, the experience of application of the methods for comprehensive rehabilitation is presented with special reference to remedial exercises, manual therapy, massage, and other physiotherapeutic procedures. Positive experience with the application of orthopedic devices is described including the Shants collars and corsets as well as the observance of the specific orthopedic locomotor regimen. These combined measures are designed to enhance the quality of life of the patients, correct their neurologic symptoms, and improve the compromised academic performance.

Neural tissue transplantation, repair, and rehabilitation

Transplants of cells and tissues to the central nervous system of adult mammals can, under appropriate conditions, survive, integrate, and function. In particular, the grafted cells can sustain functional recovery in animal models of a range of neurodegenerative conditions including genetic and idiopathic neurodegenerative diseases of adulthood and aging, ischemic stroke, and brain and spinal cord trauma. In a restricted subset of such conditions, cell transplantation has progressed to application in humans in early-stage clinical trials. At the present stage of play, there is clear evidence of clinical efficacy of fetal cell transplants in Parkinson disease (notwithstanding a range of technical difficulties still to be fully resolved), and preliminary claims of promising outcomes in several other severe neurodegenerative conditions, including Huntington disease and stroke. Moreover, the experimental literature is increasingly suggesting that the experience and training of the graft recipient materially affects the functional outcome. For example, environmental enrichment, behavioral activity, and specific training can enhance the recovery process to maximize functional recovery. There are even circumstances where the grafted cells have been demonstrated to restore the neural substrate for new learning. Consequently, it is not sufficient to replace lost cells anatomically; rather, for the grafts to be effective, they need to be integrated functionally into the host circuitry, and the host animal requires training and rehabilitation to maximize function of the reconstructed graft-host circuitry. Such observations require reconsideration of the design of the next generation of clinical trials and subsequent service delivery, to include physiotherapists, cognitive therapists, and rehabilitation experts as core members of the transplant team, along with the neurologists and neurosurgeons that have conventionally led the field.

Accuracy of a Brain Computer Interface (P300 spelling device) used by people with motor impairments

A Brain-Computer Interface (BCI) provides a completely new output pathway and so, an additional possible way a person can express himself if he/she suffers from disorders like amyotrophic lateral sclerosis (ALS), brainstem stroke, brain or spinal cord injury, or other diseases which impair the function of the common output pathways which are responsible for the control of muscles or impair the muscles. Although most BCIs are thought to help people with disabilities, they are mainly tested on healthy, young subjects who may achieve better results than people with impairments. In this study we compare measurements, performed on 10 physically disabled people, to the results of a previous study, taken using 100 healthy participants. We prove that, under certain constraints, most patients are able to control a P300-based spelling device with almost the same accuracy as the healthy ones. Tuning parameters are discussed, as well as criteria for people who are not able to use this device.

The current theoretical assumptions of the Bobath concept as determined by the members of BBTA

The Bobath concept is a problem-solving approach to the assessment and treatment of individuals following a lesion of the central nervous system that offers therapists a framework for their clinical practice. The aim of this study was to facilitate a group of experts in determining the current theoretical assumptions underpinning the Bobath concept.A four-round Delphi study was used. The expert sample included all 15 members of the British Bobath Tutors Association. Initial statements were identified from the literature with respondents generating additional statements. Level of agreement was determined by using a five-point Likert scale. Level of consensus was set at 80%. Eighty-five statements were rated from the literature along with 115 generated by the group. Ninety-three statements were identified as representing the theoretical underpinning of the Bobath concept. The Bobath experts agreed that therapists need to be aware of the principles of motor learning such as active participation, opportunities for practice and meaningful goals. They emphasized that therapy is an interactive process between individual, therapist, and the environment and aims to promote efficiency of movement to the individual's maximum potential rather than normal movement. Treatment was identified by the experts as having "change of functional outcome" at its center.

[Early neurological-neurosurgical rehabilitation. Current state]

In German neurorehabilitation, the ambiguous term "early rehabilitation" reflects the multidisciplinary, rehabilitative treatment of severely impaired patients in continuing need of acute and intensive care (including weaning from the respirator in selected cases). The actual definition of this treatment is discussed, which hitherto corresponded to Phase B according to recommendations of the German Federal Study Group for Rehabilitation (BAR) and now has started to be integrated into the diagnosis-related group system. The tasks and aims of early rehabilitation are to support and enhance neuroplastic remission of nervous system functional loss and continued medical care, improve vigilance, establish cooperativity, and evaluate the rehabilitation potential including compensatory and adaptive strategies organizing posthospital care, reducing the need of nursing support, and improving quality of life. Some special aspects of early rehabilitative care are presented here in more detail. To fulfill these tasks, a multidisciplinary team is required including various therapists qualified for neurorehabilition, physicians (including a neurologist), nurses, and social workers. Outcome data were assessed using our 5-year prospective early rehabilitation registry. Fifty-five percent of patients improved to reach the next step of neurorehabilitation (Phase C), with significant gain in function even in the subgroup of aged and most severely disabled patients. The trend to transfer patients very early in the postacute Phase to early rehabilitation facilities, with open medical problems and increased risk of complications, makes close cooperation and interaction with acute medical centers necessary.

New advances in the rehabilitation of CNS diseases applying rTMS

Transcranial magnetic stimulation (TMS) can directly stimulate the CNS, modifying the brain's plasticity to enhance the behavior of the paretic extremities. Studies with low-frequency repetitive TMS (rTMS) on the intact hemisphere and those with high frequencies on the affected hemisphere could increase the speed of movement in the hand affected by CNS injury. Stimulation of the motor pathway may contribute to faster improvement in patients with spinal cord injury. Symptoms of Parkinson's disease (such as cognition and working memory, neglect syndrome and global aphasia) can be influenced by rTMS. However, the site of stimulation and the parameters of rTMS are different. Processes that contribute to the behavior of rTMS include the modification of brain plasticity, induction of neurogenesis, growth of new fibers in the spinal cord or all of these together. According to previous research, rTMS may be suitable as an add-on therapy to rehabilitation in CNS diseases.

Balance of a Multijoint Biomechanical System in Natural and Artificial Environments: A Simulation Model

The paper is devoted to a neurobionic simulation model for controlling balance in a biomechanical pendulum. The model is realized by a complex of fuzzy regulators and an artificial neural network. Fuzzy regulators are used for simulating the physiological characteristics of the motor system and the functions of the sensory systems. The second level of control is the central integrator. It is realized as an artificial neural network (ANN), which simulates a real process of analysis and synthesis of afferent signals, formation of the model of action, etc.Equilibrium control in a multijoint biomechanical object is a specific example of a self-developing multilevel system of movement control. In the course of elaboration of the model and further examination of its behavior we have received model results which revealed correspondence with the results demonstrated by real subjects in stabilographic tests performed after long-term space flights. We concluded that the model permits us to simulate the peculiarities of human movement control and can be used for creating individual plans of recovery and rehabilitation of patients after long-term motionless or learning movement control in unknown environments.

Defining the Bobath concept using the Delphi technique

BACKGROUND AND PURPOSE

The Bobath concept, based on the work of Berta and Karel Bobath, offers therapists working in the field of neurological rehabilitation a framework for their clinical interventions. It is the most commonly used approach in the UK. Although they recognize that over the last half-century the concept has undergone considerable developments, proponents of the Bobath concept have been criticized for not publishing these changes. The aim of the present study was to use the Delphi technique to enable experts in the field to define the current Bobath concept.

METHOD

A four-round Delphi study design was used. The sample included all members of the British Bobath Tutor's Association, who are considered experts in the field. Initial statements were identified from the literature, with respondents generating additional statements during the study. The level of agreement was determined using a five-point Likert scale. The respondents were then provided with feedback on group opinions and given an opportunity to re-rate each statement. The level of group consensus was set at 80%.

RESULTS

Fifteen experts took part. The response rate was 85% in the first round, and 93% in each subsequent round. Ten statements from the literature were rated with a further 12 generated by the experts. Thirteen statements achieved consensus for agreement and seven for disagreement.

CONCLUSIONS

The Delphi study was an effective research tool, maintaining anonymity of responses and exploring expert opinions on the Bobath concept. The experts stated that Bobath's work has been misunderstood if it is considered as the inhibition of spasticity and the facilitation of normal movement, as described in some literature. They agreed that the Bobath concept was developed by the Bobaths as a living concept, understanding that as therapists' knowledge base grows their view of treatment broadens.

Understanding Guillain-Barré Syndrome and Central Nervous System Involvement

Guillain-Barré syndrome is a rare neurological disease that causes paralysis and may necessitate hospitalization for some patients in its acute stages. It primarily affects the peripheral nervous system, though recent research has shown that for some patients, the central nervous system is involved. The acute phase often requires intensive care services. Recognition is growing that recovery is not as smooth and free of symptoms as previously thought. Following "recovery" some people endure long-term residual symptoms, such as fatigue and pain. Nursing input can be of value by providing support, information, explanations, and empathy to reassure patients and families. A greater understanding of the nature and course of the disease and its ramifications can lead to more effective nursing management and a faster rehabilitation process.
