Economic evaluation of management strategies for complex regional pain syndrome (CRPS).

Background: The economic impact of Complex Regional Pain Syndrome (CRPS) on both patients and the global healthcare system continues to escalate. However, the economic implications associated with management interventions for CRPS have received limited attention. Therefore, our objective is to perform a thorough examination of published economic assessments of the various management strategies utilized for CRPS. Methods: A thorough search spanning four general medical databases and three health economic databases to identify full economic evaluations on CRPS management strategies from January 1994 to June 2023 were conducted. The quality of these studies were evaluated by employing the Consolidated Health Economic Evaluation Reporting Standards (CHEERS) statement. To enable cross-study comparisons conducted in different countries, we adjusted the costs reported in the selected studies for inflation and converted them into 2023 US dollars. Results: A total of nine economic evaluations, consisting of eight high-quality and one medium-quality, were identified across five nations during a span of 29 years. The findings suggest that the most economically efficient intervention for CRPS are interventional approaches of Spinal Cord Stimulation (SCS) in comparison to conventional management for long periods of time. Furthermore, in situations where there is a limited time period of less than 1 year, rehabilitation therapies, particularly physical therapy, have been demonstrated to be more effective in terms of both cost and clinical outcomes. Conclusion: The interventional management strategies, particularly for severe and persistent CRPS over long periods, may offer the greatest cost efficiency. In conditions with limited timelines, rehabilitation measures, such as rehabilitation therapies, can be cost-effective. However, insufficient data for other common interventions prevents the formation of a definitive conclusion. Similarly, it is crucial to recognize that the results of these interventions might be affected by the selection of comparator and the threshold for willingness to pay.

Effects of transcranial direct current stimulation alone and in combination with rehabilitation therapies on gait and balance among individuals with Parkinson's disease: a systematic review and meta-analysis.

BACKGROUND: Parkinson's disease (PD) is a neurogenerative disorder implicated in dysfunctions of motor functions, particularly gait and balance. Transcranial direct current stimulation (tDCS) is a noninvasive brain stimulation offered as a potential adjuvant therapy for PD. This systematic review and meta-analysis were conducted to identify whether tDCS alone and combined with additional rehabilitation therapies improve gait and balance among individuals with PD. METHODS: We searched PubMed, Embase, Web of Science, and relevant databases for eligible studies from inception to December 2022. Studies with a comparative design investigating the effects of tDCS on motor functions, including gait and balance among individuals with PD, were included. A meta-analysis was performed for each outcome using a random effects model for subgroup analysis and pooling of overall effect sizes. RESULTS: A total of 23 studies were included in the meta-analysis. The pooled results revealed that tDCS has moderate overall effects on gait, measured by gait speed (standardized mean deviation [SMD] = 0.238; 95% confidence interval [CI] - 0.026 to 0.502); stride length (SMD = 0.318; 95% CI - 0.015 to 0.652); cadence (SMD = - 0.632; 95% CI - 0.932 to - 0.333); freezing of gait questionnaire scores (SMD = - 0.360; 95% CI - 0.692 to - 0.027); step length (SMD = 0.459; 95% CI - 0.031 to 0.949); walking time (SMD = - 0.253; 95% CI - 0.758 to 0.252); stride time (SMD = - 0.785; 95% CI: - 1.680 to 0.111); double support time (SMD = 1.139; 95% CI - 0.244 to 0.523); and balance, measured by timed up and go (TUG) test (SMD = - 0.294; 95% CI - 0.516 to - 0.073), Berg balance scale (BBS) scores (SMD = 0.406; 95% CI - 0.059 to 0.87), and dynamic gait index (SMD = 0.275; 95% CI - 0.349 to 0.898). For the subgroup analysis, gait and balance demonstrated moderate effect sizes. However, only cadence, stride time, and TUG indicated a significant difference between real and sham tDCS (P = 0.027, P = 0.002, and P = 0.023, respectively), whereas cadence and BBS (P < 0.01 and P = 0.045, respectively) significantly differed after real tDCS plus other therapies rather than after sham tDCS plus other therapies. CONCLUSIONS: Our results indicated that tDCS is significantly associated with gait and balance improvements among individuals with PD. The findings of this study provide more proof supporting the effectiveness of tDCS, encouraging tDCS to be utilized alone or in combination with other therapies in clinical practice for PD rehabilitation.

Oncologic Rehabilitation in the COVID-19 Pandemic: The Situation in Clinics.

BACKGROUND: Oncological rehabilitation is an important pillar in the treatment of cancer patients. Due to the COVID-19 pandemic, this form of therapy is particularly challenged, as it relies heavily on group therapies. The aim of the study was to find out what impact the pandemic has had on oncological rehabilitation so far and how the rehabilitation clinics have dealt with it. METHODS: A web-based survey was used to collect data from 14 oncological rehabilitation clinics on the impact of the COVID-19 pandemic on occupancy, staffing trends, and hygiene measures for the observation period from March 1, 2020, to February 28, 2021. The data were compared with the same period 1 year earlier. In addition, the compensatory measures taken with regard to therapy were recorded. RESULTS: While only 15,272 patients were rehabilitated in the period under review, 21,257 patients were rehabilitated in the same period 1 year earlier. This corresponds to a decrease in occupancy of 28%. Three clinics were affected by temporary closures due to the pandemic. In 39% of the clinics, screening tests for patients had already been started for more than 8 months, while this was also offered to staff in only 23% of the clinics. With regard to changes in the therapeutic offer, more physiotherapeutic small groups with a reduced number of participants were used. This was also used in the area of sports therapy and education offers by 73% and 60% of the clinics, respectively. Overall, 92% of the participants assumed an economic recovery at the time of the survey. CONCLUSION: Despite a considerable decrease in occupancy in the oncological rehabilitation clinics, the therapies could be changed and carried out in a hygiene-compliant manner. Screening tests were offered at an early stage for patients as well as somewhat delayed for staff. The data show that pandemic-consistently changes in oncological rehabilitation are possible and that supply chains can be maintained.

Pre-operative neurodevelopmental assessment in young children undergoing cardiac surgery in central South Africa: feasibility and clinical value.

BACKGROUND: Pre-operative neurodevelopmental assessment in children with congenital heart disease may assist in the early identification of children at risk for or presenting with developmental delays. This study determined the pre-operative neurodevelopmental status of young children undergoing cardiac surgery in central South Africa. Feasibility and clinical value of pre-operative assessment were also evaluated. METHODS: Children 30 months and younger, scheduled to undergo cardiac surgery, were recruited into this prospective observational analytical study. Neurodevelopmental status was assessed using the Bayley-III and neuromotor examination. Variables associated with developmental performance were determined using ANOVAs. Sociodemographic and medical information were collected using a self-developed questionnaire. Pre-operative neurodevelopmental assessment was completed for 40 children at a median age of 7.4 months, including 30 children without and 10 with Down syndrome. Mean cardiac disease severity was moderate. The inclusion rate for pre-operative developmental assessment was 68%, limited mainly by environmental barriers. RESULTS: Children with Down syndrome had significantly poorer motor (p < 0.0001), cognitive (p < 0.0001) and language performance (p < 0.001) compared to children without Down syndrome. Apart from Down syndrome, disease severity (p = 0.02), younger age at first cardiac surgery (p < 0.01) and growth failure (p = 0.04) were significantly associated with poorer cognitive, language and motor performance, respectively. Just more than half of the children without (n = 16) and all children with Down syndrome (n = 10) scored below one standard deviation of the test mean score (scores < 85) on at least one of the Bayley-III subscales, meeting the criteria for referral to rehabilitation therapies, including physiotherapy, occupational therapy and/or speech therapy. CONCLUSION: Pre-operative neurodevelopmental assessment may be of high importance in South Africa to identify children at developmental risk, facilitating early referral to rehabilitation therapies.

Neonatal stroke: Clinical characteristics and neurodevelopmental outcomes.

BACKGROUND: Neonatal stroke can potentially result in significant neurological sequelae in affected infants. Studies on neurodevelopmental outcomes and the need for rehabilitation therapies in the first two years are limited. We aimed to describe the clinical characteristics, diagnostic evaluation, and neurodevelopmental outcomes of a cohort of infants with neonatal stroke. METHODS: A retrospective cohort study of infants with neonatal stroke, from 2011 to 2020. Maternal and infant characteristics were described. Placental pathology, echocardiogram results, and prothrombotic evaluations were reported. The neurodevelopmental outcomes using Bayley scale of infant development (BSID III), rates of epilepsy and cerebral palsy, and the need for rehabilitation therapies at two years were described. RESULTS: During the study period, 55 infants had neonatal stroke. Majority (93%) were term or late preterm infants. Maternal chorioamnionitis and perinatal HIE were diagnosed in about a third of the infants. Most (66%) of the infants presented with seizures. On brain MRI, the lesions were unilateral in 76% and arterial in origin in 86% of the infants. Meconium exposure (42%), intrauterine inflammation/infection (37%) and fetal vascular malperfusion (16%) were seen on placental histopathology. At two-year BSID III assessment, median (min, max) composite cognitive, language, and motor scores were 100 (55-145), 97 (47-124), and 100 (46-141), respectively. Among this cohort, epilepsy (27%), cerebral palsy (16%) and the need for rehabilitation therapies (physical -24%, occupational -18%, speech -21%) were reported at two years. CONCLUSION: Neonatal stroke presented commonly in term or late preterm infants with seizures. It was unilateral and arterial in origin in most infants. Maternal chorioamnionitis and perinatal HIE were the most commonly associated conditions at birth. About one-fifth of the infants had mild or severe developmental delays at two years. Epilepsy, cerebral palsy, and need for rehabilitation therapies were noted in a significant proportion of infants at two years.

Task specific dystonia - a patients' perspective.

BACKGROUND: Task specific dystonia (TSD) is a subtype of dystonia with no cure and significant limitations on treatments. Few studies have investigated the outcomes of rehabilitative therapy from the patient's perspective. PURPOSE OF THE STUDY: This study explored the interventions that patients have utilized and their perceived effectiveness in treating and managing their TSD, specifically musicians' dystonia (MD) and writer's dystonia (WD). Symptoms and the effect of TSD on the perceived performance of every day and specific tasks, and possible reasons why the condition developed, were also investigated. STUDY DESIGN: Descriptive survey. METHODS: Patients diagnosed with TSD, treated at a private hand therapy unit, who had consented to being contacted for research purposes, were emailed a link to an online survey (or posted if email was not available), administered via KwikSurveys. The survey consisted of 4 subsections: personal information, general medical history, dystonia medical history and dystonia treatment history. RESULTS: Invitations were sent to 105 patients of whom 90% (n = 95/105) responded. Results for both the MD and WD groups were similar. There was a significant association between the 2 groups as to what they viewed may have led to the development of TSD (a change in technique; P < .001) and the most effective treatments (massage P< .043, modifications to the instrument P< .002; ultrasound therapy P< .013.) All reported that daily activities were affected by their condition. DISCUSSION: Although full levels of task specific function (playing their instrument or writing) were not usually regained, participants with both MD and WD perceived improvement in symptoms with rehabilitation intervention. Three treatments were perceived to be most effective in achieving this, suggesting that these should be considered for inclusion within treatment plans. CONCLUSIONS: From the perspective of people with TSD, a range of rehabilitation interventions are effective in enhancing symptom management, providing further evidence to support their use.

Integración de Un Sistema Robótico de Terapia Ocupacional para Extremidades Superiores con Estimulación Visual/Táctil de Los Pacientes / Integration of an Occupational-Therapy Robotic System for Upper Limbs with Visual/tactile Stimulation of Patients

Resumen: Los ejercicios tradicionales de rehabilitación de extremidades superiores tienen como objetivo principal recuperar la fuerza o rango de movimiento del área lesionada de los pacientes. Una opción alternativa que se ha presentado en los últimos años es el uso de interfaces hápticas, las cuales han mostrado ser herramientas potenciales en el apoyo de las terapias de rehabilitación. En este artículo se presenta un sistema de rehabilitación háptico de movimientos finos en extremidades superiores, cuya característica principal es que los usuarios del sistema pueden interactuar de forma visual y táctil con objetos virtuales mezclados con escenarios reales logrando con ello un ambiente de realidad aumentada. El sistema fue probado en dos etapas, ambas con sujetos que presentaban un grado de discapacidad en extremidades superiores. Los datos recopilados fueron trayectorias seguidas, errores de seguimiento y la actividad muscular obtenida por medio de electromiografía; esta información recolectada permitió analizar de forma cuantitativa el grado de avance de los pacientes. Además, se consideraron las valoraciones hechas por fisioterapeutas, concluyendo que el sistema propuesto puede ser utilizado como una herramienta viable que complementa a las terapias de rehabilitación convencionales.

Abstract: Traditional upper limb rehabilitation exercises are primarily aimed at regaining the strength or range of motion of the patients' injured area. An alternative option that has been presented in the last years is the use of haptic interfaces, which have shown their potential as tools that support rehabilitation therapies. This article presents a haptic system of rehabilitation for fine upper limb movements, whose main characteristic is that users of the system can interact in a visual and tactile fashion with virtual objects mixed with real scenarios, thereby achieving an augmented reality environment. The system was tested in two stages, both with subjects who had a degree of disability in upper limbs. The data collected were followed trajectories, follow-up errors and the muscular activity obtained by means of electromyography; the collected information enabled the analysis, in a quantitative way, of the degree of progress of the patients. In addition, the assessments made by physiotherapists were considered, concluding that the proposed system can be used as a viable complementary tool for conventional rehabilitation therapies.

Impedance control in a wave-based teleoperator for rehabilitation motor therapies assisted by robots.

This paper presents an improved wave-based bilateral teleoperation scheme for rehabilitation therapies assisted by robot manipulators. The main feature of this bilateral teleoperator is that both robot manipulators, master and slave, are controlled by impedance. Thus, a pair of motion-based adaptive impedance controllers are integrated into a wave-based configuration, in order to guarantee a stable human-robot interaction and to compensate the position drift, characteristic of the available schemes of bilateral teleoperation. Moreover, the teleoperator stability, in the presence of time delays in the communication channel, is guaranteed because the wave-variable approach is included to encode the force and velocity signals. It should be noted that the proposed structure enables the implementation of several teleoperator schemes, from passive therapies, without the intervention of a human operator on the master side, to fully active therapies where both manipulators interact with humans in a stable manner. The suitable performance of the proposed teleoperator is verified through some results obtained from the simulation of the passive and active-constrained modes, by considering typical tasks in motor-therapy rehabilitation, where an improved behavior is observed when compared to implementations of the classical wave-based approach.

Movement-based interaction applied to physical rehabilitation therapies.

BACKGROUND: Health care environments are continuously improving conditions, especially regarding the use of current technology. In the field of rehabilitation, the use of video games and related technology has helped to develop new rehabilitation procedures. Patients are able to work on their disabilities through new processes that are more motivating and entertaining. However, these patients are required to leave their home environment to complete their rehabilitation programs. OBJECTIVE: The focus of our research interests is on finding a solution to eliminate the need for patients to interrupt their daily routines to attend rehabilitation therapy. We have developed an innovative system that allows patients with a balance disorder to perform a specific rehabilitation exercise at home. Additionally, the system features an assistive tool to complement the work of physiotherapists. Medical staff are thus provided with a system that avoids the need for them to be present during the exercise in specific cases in which patients are under suitable supervision. METHODS: A movement-based interaction device was used to achieve a reliable system for monitoring rehabilitation exercises performed at home. The system accurately utilizes parameters previously defined by the specialist for correct performance of the exercise. Accordingly, the system gives instructions and corrects the patient's actions. The data generated during the session are collected for assessment by the specialist to adapt the difficulty of the exercise to the patient's progress. RESULTS: The evaluation of the system was conducted by two experts in balance disorder rehabilitation. They were required to verify the effectiveness of the system, and they also facilitated the simulation of real patient behavior. They used the system freely for a period of time and provided interesting and optimistic feedback. First, they evaluated the system as a tool for real-life rehabilitation therapy. Second, their interaction with the system allowed us to obtain important feedback needed to improve the system. CONCLUSIONS: The system improves the rehabilitation conditions of people with balance disorder. The main contribution comes from the fact that it allows patients to carry out the rehabilitation process at home under the supervision of physiotherapists. As a result, patients avoid having to attend medical centers. Additionally, medical staff have access to an assistant, which means their presence is not required in many exercises that involve constant repetition.
