Economic Cost of Rehabilitation with Robotic and Virtual Reality Systems in People with Neurological Disorders: A Systematic Review.

Background: The prevalence of neurological disorders is increasing worldwide. In recent decades, the conventional rehabilitation for people with neurological disorders has been often reinforced with the use of technological devices (robots and virtual reality). The aim of this systematic review was to identify the evidence on the economic cost of rehabilitation with robotic and virtual reality devices for people with neurological disorders through a review of the scientific publications over the last 15 years. Methods: A systematic review was conducted on partial economic evaluations (cost description, cost analysis, description of costs and results) and complete (cost minimization, cost-effectiveness, cost utility and cost benefit) studies. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. The main data sources used were PubMed, Scopus and Web of Science (WOS). Studies published in English over the last 15 years were considered for inclusion in this review, regardless of the type of neurological disorder. The critical appraisal instrument from the Joanna Briggs Institute for economic evaluation and the Consolidated Health Economic Evaluation Reporting Standards (CHEERS) were used to analyse the methodological quality of all the included papers. Results: A total of 15 studies were included in this review. Ten papers were focused on robotics and five on virtual reality. Most of the studies were focused on people who experienced a stroke. The robotic device most frequently used in the papers included was InMotion® (Bionik Co., Watertown, MA, USA), and for those focused on virtual reality, all papers included used semi-immersive virtual reality systems, with commercial video game consoles (Nintendo Wii® (Nintendo Co., Ltd., Kyoto, Japan) and Kinect® (Microsoft Inc., Redmond, WA, USA)) being used the most. The included studies mainly presented cost minimization outcomes and a general description of costs per intervention, and there were disparities in terms of population, setting, device, protocol and the economic cost outcomes evaluated. Overall, the methodological quality of the included studies was of a moderate level. Conclusions: There is controversy about using robotics in people with neurological disorders in a rehabilitation context in terms of cost minimization, cost-effectiveness, cost utility and cost benefits. Semi-immersive virtual reality devices could involve savings (mainly derived from the low prices of the systems analysed and transportation services if they are applied through telerehabilitation programmes) compared to in-clinic interventions.

Effects of the powerball® system on muscle strength, coordination, fatigue, functionality and quality of life in people with multiple sclerosis. A randomized clinical trial.

INTRODUCTION: Although clinical and functional impairments in the lower limbs have been extensively studied in patients with MS, the upper limb (UL) are also frequently affected. Clinical impairment of the UL in patients with MS is very common with muscle strength and hand dexterity as critical factors in maintaining functional activities that are the basis for independence and quality of life in people with MS. OBJECTIVE: To investigate the effects of a training protocol using the Powerball® system in combination with conventional physiotherapy on muscle strength, coordination, fatigue, functionality, and quality of life in persons with MS over an 8-week period. MATERIALS AND METHODS: A double-blind randomized controlled trial was conducted. The control group received conventional treatment, while the experimental group received additional UL training using the Powerball® system. Both groups received the same number of sessions and weeks of intervention. The following outcome measures were used: isometric grip and pinch strength, Box and Block Test (BBT), Nine Hole Peg Test (NHPT), Abilhand scale, Fatigue Severity Scale (FSS), Multiple Sclerosis Impact Scale (MSIS-29), and Likert satisfaction questionnaire for the experimental group. All measures were administered at baseline, after the treatment, and during a 3-week follow-up period. RESULTS: 25 patients completed the study (12 in the experimental and 13 in the control group). The experimental group showed significant improvements in coordination and manual dexterity of the more affected UL as measured by the BBT comparing pre- to post-treatment (p = 0.048) and pre-treatment to follow-up (p = 0.001), and on the less affected UP comparing pre-treatment to follow-up (p < 0.001) and post-treatment to follow-up (p = 0.034). The Likert-type satisfaction questionnaire obtained a mean score of 89.10 (± 8.54) out of 100 points. CONCLUSIONS: Upper limb treatment protocol using the Powerball® system, in combination with conventional physiotherapy for 8 weeks resulted in significant improvements in the intra-group analysis for UL coordination and manual dexterity in favor of the experimental group. The experimental group showed excellent satisfaction to the treatment.

Differences in Motor Development between Preterm Infants and Full-Term Preschool Children.

Although advances in obstetric and neonatal care have improved the survival of preterm infants, many studies document the increased risk of motor and sensory neurodevelopmental abnormalities that can hinder school progress. The aim of this study was to analyze the differences in gross and fine motor development in children born preterm and full term aged 3 to 6 years using the Peabody Developmental Motor Scales 2 (PDMS-II). Fifteen preterm and fifteen term children, matched for age and sex, participated in this study. They were evaluated with the PDMS-II scale. The scores obtained in the PDMS-II scale showed statistically significant differences (p < 0.05) in all subscales except for the "grasping" subscale. No dissimilarities were found between children who attended an early intervention program and those who did not participate, nor was there any correlation between week of gestation and birth weight and motor development in preschool. The results obtained show that differences are found with respect to motor development, with lower scores for those born preterm compared to children born at term. No statistically significant difference was found between preterm children who attended early intervention and those who did not. No correlation was found between motor development at preschool age and birth weight and gestational age.

Designing an Informative App for Neurorehabilitation: A Feasibility and Satisfaction Study by Physiotherapists.

BACKGROUND: New technologies have gained popularity, especially the use of mobile phone applications, in neurorehabilitation. The aim of this paper was (1) to develop a free mobile application (NeurorehAPP) that provides information about and helps to select the appropriate mobile application related to a list of neurological disorders (cognitive impairment, Alzheimer's disease, Parkinson's disease, multiple sclerosis, traumatic brain injury, stroke, cerebral palsy, muscular dystrophy, spina bifida, and facial paralysis), based on different objectives such as healthy habits, information, assessment, and treatment; and (2) to assess the feasibility, acceptability, and degree of satisfaction by physiotherapists after using NeurorehAPP for a minimum of three months. METHODS: A free application was created to work with the Android® operating system. The degree of satisfaction and acceptance with the application was assessed with an adaptation of the Customer Satisfaction Questionnaire through a survey via email applied to physiotherapists from hospitals and neurological rehabilitation centers in Spain after using the application. RESULTS: NeurorehAPP includes a total of 131 apps. A total of 121 physiotherapists completed a satisfaction survey. The total sample showed 85.41% satisfaction with the service provided by the app and 86.41% overall satisfaction with NeurorehAPP. CONCLUSIONS: NeurorehAPP is a free, intuitive, and friendly app used with the Android® operating system that allows the selection of the most appropriate app according to the type of user, neurological disorder, objective, and FDA criteria. Physiotherapists showed a high degree of satisfaction and acceptance with NeurorehAPP.

The Use of Portable Devices for the Instrumental Assessment of Balance in Patients with Chronic Stroke: A Systematic Review.

BACKGROUND: Improving balance remains a challenge in stroke rehabilitation. The technological development has allowed the design of more accessible and user-friendly systems for assessing postural control. OBJECTIVES: The aim of this review was to analyze portable devices for the instrumental assessment of balance in patients with chronic stroke. METHODS: PRISMA guidelines were used to carry out the systematic review. The literature search was restricted to articles written in English or Spanish published from 2013 to December 2022 in Pubmed, Web of Science, Scopus, PEDro, and CINAHL. Of the 309 search results, 229 unique references were reviewed after duplicates were removed. The PEDro scale was applied to evaluate the methodological quality of the included papers, and the degree of evidence and level of recommendation were determined through the Oxford Centre for Evidence-Based Medicine. RESULTS: A total of seven articles reporting on five different balance testing devices were included in this systematic review; they regarded BIORescue, a smartphone application, and the Biodex-BioSway Balance System for the evaluation of standing balance, and SwayStar Balance and Xsens ForceShoes™ for the evaluation of dynamic balance during walking. CONCLUSIONS: The use of portable devices that assess balance in adult patients with chronic stroke is scarce.

Transcranial direct current stimulation in the management of phantom limb pain: a systematic review of randomized controlled trials.

INTRODUCTION: Phantom limb pain (PLP) after amputation is a frequent entity that conditions the life of those who suffer it. Current treatment methods are not sufficiently effective for PLP management. We aim to analyze the clinical application of transcranial direct current (tDCS) in people with amputation suffering from PLP. EVIDENCE ACQUISITION: The following databases were consulted in September 2021: MEDLINE, EMBASE, The Web of Science, PEDro, SCOPUS and SciELO. Randomized controlled trials investigating the use of tDCS in people with amputation undergoing PLP were selected. Demographic data, type and cause of amputation, time since amputation, stimulation parameters, and outcomes were extracted. EVIDENCE SYNTHESIS: Six articles were included in this review (seven studies were considered because one study performed two individual protocols). All included studies evaluated PLP; six evaluated the phantom limb sensations (PLS) and two evaluated the psychiatric disorders. In all included studies the intensity and frequency of PLP was reduced, in three PLS were reduced, and in none study psychiatric symptoms were modified. CONCLUSIONS: Anodic tDCS over the contralateral M1 to the affected limb, with an intensity of 1-2 mA, for 15-20 minutes seems to significantly reduce PLP in people with amputation. Single-session treatment could modify PLP intensity for hours, and multi-session treatment could modify PLP for months. Limited evidence suggests that PLS and psychiatric disorders should be treated with different PLP electrode placements. Further studies with larger sample size and longer follow-up times are needed to establish the priority of tDCS application in the PLP management.

Test-Retest Reliability of a Conventional Gait Model for Registering Joint Angles during Initial Contact and Toe-Off in Healthy Subjects.

The aim of this study was to evaluate the test-retest reliability of a conventional gait model (CGM), the Plug-in Gait model, to calculate the angles of the hip, knee, and ankle during initial contact (IC) and toe-off (TO). Gait analysis was performed using the Vicon Motion System® (Oxford Metrics, Oxford, UK). The study group consisted of 50 healthy subjects. To evaluate the test-retest reliability, the intraclass correlation coefficient (ICC), the standard error of measurement (SEM), the minimal detectable change (MDC), and the Bland-Altman analysis with 95% limits of agreement were calculated. The ICC for the joint angles of the hip, knee, and ankle was higher than 0.80. However, the ankle angle at IC had an ICC lower than 0.80. The SEM was <5° for all parameters. The MDC was large (>5°) for the hip angle at IC. The Bland-Altman analysis indicated that the magnitude of divergence was between ±5° and ±9° at IC and around ±7° at TO. In conclusion, the ICC for the plug-in gait model was good for the hip, knee, and ankle angles during IC and TO. The plots revealed a disagreement between measurements that should be considered in patients' clinical assessments.

Ankle muscle activation during the limits of stability test in subjects with chronic ankle instability.

OBJECTIVE: To study postural control and muscle activity during the limit of stability test (LOS) in subjects with chronic ankle instability. DESIGN: Observational study. SETTING: University laboratory. PARTICIPANTS: 10 healthy subjects were included in the control group and 10 subjects in the CAI group (age between 18 and 30 years, with history of the multiple ankle "giving way" episodes in the last six months and score ≤24 in the Cumberland Ankle Instability Tool). MAIN OUTCOME MEASURES: A computerized dynamic posturography equipment was used for assessing the LOS. The electromyography activity of tibialis anterior (TA), soleus (SOL), medial gastrocnemius (MG) and peroneus longus (PL) was registered. RESULTS: Subjects with CAI had a greater activation in TA to forward (p < .01), forward affected (p = .001), backward affected (p = .007) and backward directions (p < .01); in PL to forward affected (p < .01) and affected directions (p = .001); in MG to forward (p = .023) and affected directions (p < .01) and in SOL to the affected direction (p = .009). We observed restricted excursions and less directional control in subjects with CAI. CONCLUSIONS: Subjects with CAI exhibited poorer ability to move their center of gravity within stability limits. In addition, they have an altered ankle muscle activity during LOS test toward the affected ankle joint.

OBJETIVO: Analizar los efectos de esta intervención en la marcha, el equilibrio y la fuerza muscular en personas con lesión medular incompleta en comparación con un tratamiento de fisioterapia convencional o con un entrenamiento de la marcha sobre suelo. PACIENTES Y MÉTODOS: Se realizó una recopilación de ensayos clínicos desde 2007 hasta 2019. Se incluyeron trabajos que evaluasen el entrenamiento de la marcha con soporte parcial del peso corporal en cinta rodante en pacientes con lesión medular incompleta y que analizasen la marcha, el equilibrio y la fuerza muscular. RESULTADOS: Se analizaron seis artículos. Según los resultados de los estudios incluidos, la cadencia, la velocidad y la resistencia de marcha mejoraron en los participantes que recibieron entrenamiento sobre pasarela rodante con soporte parcial del peso corporal respecto al grupo de control.Las variables de funcionalidad, equilibrio y fuerza mejoraron en la mayoría de estudios, pero no hubo diferencias entre ambos grupos. CONCLUSIONES: El entrenamiento de la marcha con soporte parcial del peso corporal sobre cinta rodante mejora los parámetros espaciotemporales de la marcha y la resistencia de los pacientes con lesión medular incompleta, pero, en la mayoría de las variables analizadas, los cambios no son superiores a los observados tras un entrenamiento convencional

INTRODUCTION: The partial body weight supported treadmill training is a common therapeutic strategy in rehabilitation of people with spinal cord injuries. AIM: To analyze its effects on gait, balance and muscle strength in people with incomplete spinal cord injury compared to conventional treatment or overground gait training. PATIENTS AND METHODS: A compilation of clinical trials from 2007 to 2019 was carried out. We included articles that evaluate the effects of body weight supported treadmill training on gait, balance and muscle strength in subjects with incomplete spinal cord injury. RESULTS: A total of six articles were analyzed. The walking cadence, speed and resistance improved in the participants that received the intervention compared to those that were treated with conventional training. The functionality, balance and strength improved in most studies, but there were not differences between them. CONCLUSIONS: Body weight supported treadmill training improves the spatiotemporal parameters of walking and resistance in subjects with incomplete spinal cord injury, but in most variables analyzed (balance, functionality and strength) the changes are not superior to those observed after conventional training

Reliability of Kinovea® Software and Agreement with a Three-Dimensional Motion System for Gait Analysis in Healthy Subjects.

Gait analysis is necessary to diagnose movement disorders. In order to reduce the costs of three-dimensional motion capture systems, new low-cost methods of motion analysis have been developed. The purpose of this study was to evaluate the inter- and intra-rater reliability of Kinovea® and the agreement with a three-dimensional motion system for detecting the joint angles of the hip, knee and ankle during the initial contact phase of walking. Fifty healthy subjects participated in this study. All participants were examined twice with a one-week interval between the two appointments. The motion data were recorded using the VICON Motion System® and digital video cameras. The intra-rater reliability showed a good correlation for the hip, the knee and the ankle joints (Intraclass Correlation Coefficient, ICC > 0.85) for both observers. The ICC for the inter-rater reliability was >0.90 for the hip, the knee and the ankle joints. The Bland-Altman plots showed that the magnitude of disagreement was approximately ±5° for intra-rater reliability, ±2.5° for inter-rater reliability and around ±2.5° to ±5° for Kinovea® versus Vicon®. The ICC was good for the hip, knee and ankle angles registered with Kinovea® during the initial contact of walking for both observers (intra-rater reliability) and higher for the agreement between observers (inter-rater reliability). However, the Bland-Altman plots showed disagreement between observers, measurements and systems (Kinovea® vs. three-dimensional motion system) that should be considered in the interpretation of clinical evaluations.

Leap motion controlled video game-based therapy for upper limb rehabilitation in patients with Parkinson's disease: a feasibility study.

BACKGROUND: Non-immersive video games are currently being used as technological rehabilitation tools for individuals with Parkinson's disease (PD). The aim of this feasibility study was to evaluate the effectiveness of the Leap Motion Controller® (LMC) system used with serious games designed for the upper limb (UL), as well as the levels of satisfaction and compliance among patients in mild-to-moderate stages of the disease. METHODS: A non-probabilistic sampling of non-consecutive cases was performed. 23 PD patients, in stages II-IV of the Hoehn & Yahr scale, were randomized into two groups: an experimental group (n = 12) who received treatment based on serious games designed by the research team using the LMC system for the UL, and a control group (n = 11) who received a specific intervention for the UL. Grip muscle strength, coordination, speed of movements, fine and gross UL dexterity, as well as satisfaction and compliance, were assessed in both groups pre-treatment and post-treatment. RESULTS: Within the experimental group, significant improvements were observed in all post-treatment assessments, except for Box and Blocks test for the less affected side. Clinical improvements were observed for all assessments in the control group. Statistical intergroup analysis showed significant improvements in coordination, speed of movements and fine motor dexterity scores on the more affected side of patients in the experimental group. CONCLUSIONS: The LMC system and the serious games designed may be a feasible rehabilitation tool for the improvement of coordination, speed of movements and fine UL dexterity in PD patients. Further studies are needed to confirm these preliminary findings.

Entrenamiento de las señales corticales a través de un sistema BMI-EEG, evolución e intervención. A propósito de un caso / Training cortical signals by means of a BMI-EEG system, its evolution and intervention. A case report

Introducción. En los últimos años están incorporándose nuevas tecnologías en el tratamiento fisioterapéutico de pacientes con ictus, como las interfaces cerebro-máquina -brain-machine interface (BMI)-, capaces de detectar la intención de movimiento analizando las señales corticales por medio de diferentes técnicas, como la electroencefalografía (EEG). Estas señales se traducen en comandos con el fin de realizar una función. Caso clínico. Varón de 40 años con ictus de dos meses de evolución, en el cual se empleó un dispositivo BMI-EEG. La intención de movimiento del sujeto se analizó calculando la desincronización relacionada con el evento. La función motora del miembro superior fue evaluada con la escala de Fügl-Meyer, y el nivel de satisfacción del paciente, mediante el cuestionario QUEST 2.0. La intervención se llevó a cabo sin dificultad siendo el fisioterapeuta la interfaz. Conclusiones. Los sistemas BMI-EEG detectan cambios corticales en un sujeto con ictus subagudo. Estos cambios son coherentes con los cambios observados en escalas clínicas (AU)

Introduction. In the last years, new technologies such as the brain-machine interfaces (BMI) have been incorporated in the rehabilitation process of subjects with stroke. These systems are able to detect motion intention, analyzing the cortical signals using different techniques such as the electroencephalography (EEG). This information could guide different interfaces such as robotic devices, electrical stimulation or virtual reality. Case report. A 40 years-old man with stroke with two months from the injury participated in this study. We used a BMI based on EEG. The subject’s motion intention was analyzed calculating the event-related desynchronization. The upper limb motor function was evaluated with the Fügl-Meyer Assessment and the participant’s satisfaction was evaluated using the QUEST 2.0. The intervention using a physical therapist as an interface was carried out without difficulty. Conclusions. The BMI systems detect cortical changes in a subacute stroke subject. These changes are coherent with the evolution observed using the Fügl-Meyer Assessment (AU)

Análisis instrumental de la marcha en pacientes con ictus / Instrumental gait analysis in stroke patients

Introducción. Las alteraciones en el control motor consecuentes al ictus afectan al patrón de marcha, existiendo una importante variabilidad intersujeto. Objetivos. Valorar, a través de un sistema de captura del movimiento, el patrón cinemático de la marcha en sujetos con ictus y establecer qué alteraciones del patrón de la marcha son comunes entre los participantes. Sujetos y métodos. Participaron nueve pacientes con ictus con capacidad de marcha y diez sujetos controles. Para la captura del movimiento se empleó el sistema VICON Motion System (R). Se analizaron los movimientos articulares de pelvis, cadera, rodilla y tobillo en el plano sagital, y los parámetros espaciotemporales de la marcha. Resultados. La función motora de los participantes, valorada mediante la escala Fügl-Meyer (sección del miembro inferior), osciló entre 15 y 33 puntos. Los participantes presentaron alteraciones en la cinemática comunes entre ellos. En los pacientes con ictus se registró: aumento de la amplitud de movimiento de la pelvis en ambos hemicuerpos (lado afecto y no afecto frente a control, p < 0,01); en la cadera, disminución de la máxima extensión durante la fase de apoyo en el lado afecto (p < 0,01) e incremento de la flexión en las fases de apoyo y oscilación en el no afecto (p = 0,025); en la rodilla, mayor flexión durante la fase de contacto inicial (lado afecto frente a control, p < 0,01; lado no afecto frente a control, p = 0,02); y en el tobillo, ligera flexión plantar durante la fase de contacto inicial en el lado afecto. Conclusiones. A pesar de la variabilidad clínica, existen alteraciones específicas comunes de la marcha en sujetos con ictus (AU)

Introduction. The motor control deficits after stroke affect the gait pattern. There is a significant variability between subjects. Aims. To analyse, by using a capture motion system, the gait pattern in stroke patients with different levels of motor function, and to establish, despite the participants heterogeneity, what alterations in the gait pattern are usual in each participant. Subjects and methods. Nine stroke subjects with independent gait and ten control subjects participated in this study. Motion capture was performed using the VICON Motion System (R). The motion of the pelvis, hip, knee and ankle were analyzed in the sagittal plane. Also, the spatio-temporal parameters of gait were observed. Results. The motor function evaluated using the Fügl-Meyer Assessment (lower limb section) varied between 15 and 33 points. Participants had alterations in the kinematic pattern which were common between each of them. In stroke patients it was observed: an increment of the pelvis range of motion in both sides; at the hip joint, a decrease of the maximum peak of extension during the stance phase in the affected side and a greater flexion during the stance and the swing periods in the non-affected side; at the knee, a major knee flexion during the initial contact; and at the ankle joint, an slight ankle plantar flexion during the initial contact on the affected side. Conclusions. There are several landmarks in stroke gait that the clinicians should keep attention during the walking observation (AU)
