A wearable system for visual cueing gait rehabilitation in Parkinson's disease: a randomized non-inferiority trial.

BACKGROUND: Gait disturbances represent one of the most disabling features of Parkinson's disease (PD). AIM: The aim of this study was to evaluate the non-inferiority of a new wearable visual cueing system (Q-Walk) for gait rehabilitation in PD subjects, compared to traditional visual cues (stripes on the floor). DESIGN: Open-label, monocentric, randomized controlled non-inferiority trial. SETTING: Outpatients. POPULATION: Patients affected by idiopathic PD without cognitive impairment, Hoehn and Yahr stage II-IV, Unified Parkinson's Disease Rating Scale motor section III ≥2, stable drug usage since at least 3 weeks. METHODS: At the enrollment (T0), all subjects underwent a clinical/functional evaluation and the instrumental gait and postural analysis; then they were randomly assigned to the Study Group (SG) or Control Group (CG). Rehabilitation program consisted in 10 consecutive individual sessions (5 sessions/week for 2 consecutive weeks). Each session included 60 minutes of conventional physiotherapy plus 30 minutes of gait training by Q-Walk (SG) or by traditional visual cues (CG). Follow-up visits were scheduled at the end of the treatment (T1) and after 3 months (T2). RESULTS: Fifty-two subjects were enrolled in the study, 26 in each group. The within-groups analysis showed a significant improvement in clinical scales and instrumental data at T1 and at T2, compared to baseline, in both groups. According to the between-group analysis, Q-Walk cueing system was not-inferior to the traditional cues for gait rehabilitation. The satisfaction questionnaire revealed that most subjects described the Q-Walk cueing system as simple, motivating and easily usable, possibly suitable for home use. CONCLUSIONS: Data showed that motor rehabilitation of PD subjects performed by means of the new wearable Q-Walk cueing system was feasible and as effective as traditional cues in improving gait parameters and balance. CLINICAL REHABILITATION IMPACT: Wearable devices can act as an additional rehabilitation strategy for long-term and continuous care, allowing patients to train intensively and extensively in household settings, favoring a tailor-made and personalized approach as well as remote monitoring.

La actividad física en la enfermedad de Parkinson: identificación de los responsables de su prescripción, hábitos e impacto en la calidad de vida, y de la gravedad de la enfermedad / Physical activity in Parkinson’s disease: examining prescription sources, patterns, and the influence of quality of life and disease severity

Introducción: Escasas investigaciones han explorado la influencia de la calidad de vida (CV) y la gravedad de la enfermedad en la actividad física (AF) en pacientes con enfermedad de Parkinson (EP), así como las fuentes de prescripción de AF y consejos para esta población. Este estudio tiene como objetivo ampliar el conocimiento científico sobre estos temas. Pacientes y métodos: Se entrevistó personalmente a 211 pacientes con EP para recopilar datos sobre los niveles de AF con el International Physical Activity Questionnaire-Short Form y la CV con el Parkinson’s Disease Questionnaire-8. Un cuestionario ad hoc recopiló información sobre la gravedad de la enfermedad (etapas de Hoehn y Yahr), los comportamientos de AF y las recomendaciones de AF. Resultados: Se encontraron asociaciones débiles, pero significativas, entre los niveles de AF, la gravedad de la enfermedad (r = –0,218; p = 0,004) y la CV (r = –0,244; p = 0,001). La mayoría de los participantes (85%) recibió asesoramiento sobre AF, principalmente de neurólogos, ya sea en el momento del diagnóstico (52%) o poco después (28%). Antes del inicio de la EP, ~86% participaba en AF, lo que disminuyó al 66% después del diagnóstico. Aproximadamente el 78% informó sobre cambios en la AF, incluida una reducción en la frecuencia (18,4%) y la duración (32,8%), y la caminata era la actividad principal. Conclusiones: La gravedad de la enfermedad y la CV afectan significativamente a los niveles de AF en pacientes con EP. El diagnóstico se asocia con una disminución en la frecuencia y la duración de la AF, y la caminata es la actividad preferida. Los neurólogos aconsejan principalmente sobre AF a las personas con EP.

Introduction: Limited research has explored the influence of quality of life (QoL) and disease severity on physical activity (PA) in Parkinson’s disease (PD) patients, and the sources of PA prescription and advice for this population. This study aims to expand scientific knowledge on these topics. Patients and methods: Two-hundred eleven PD patients were personally interviewed to collect data on PA levels using the International Physical Activity Questionnaire-Short Form and QoL using the Parkinson’s Disease Questionnaire-8. An ad hoc questionnaire gathered information on disease severity (Hoehn and Yahr stages), PA behaviors, and PA recommendations. Results: Weak but significant associations were found between PA levels, disease severity (r: –0.218; p = 0.004), and QoL (r: –0.244; p = 0.001). Most participants (85%) received PA counselling, predominantly from neurologists, either at diagnosis (52%) or shortly after (28%). Before PD onset, ~86% engaged in PA, decreasing to 66% post-diagnosis. Approximately 78% reported changes in PA, including reduced frequency (18.4%) and duration (32.8%), with walking as the primary activity. Conclusions: Disease severity and QoL significantly affect PA levels in PD patients. Diagnosis is associated with decreased PA frequency and duration, and walking is the preferred activity. Neurologists primarily provide PA advice.(AU)

Do patients with neurological disorders benefit from immersive virtual reality? A scoping review on the emerging use of the computer-assisted rehabilitation environment.

INTRODUCTION: Virtual reality (VR) is an advanced technology that creates simulated environments and conditions. By offering the possibility of combining motor, cognitive, and well-being in conjunction with the potential to manipulate multi-sensorial features in a safe environment, VR has emerged as a promising powerful rehabilitation tool. Among advanced VR systems, various authors have highlighted promising effects in the rehabilitation of the computer-assisted rehabilitation environment (CAREN - Motekforce Link; Amsterdam, The Netherlands). In our scoping review, we aimed to map the existing evidence on the use of CAREN in the rehabilitation of neurological patients. EVIDENCE ACQUISITION: This scoping review was conducted following the PRISMA guidelines. A search was carried out for all peer-reviewed articles published until June 30, 2023, using the following databases: PubMed, Embase, Cochrane Database, PeDro and Web of Science. The following terms have been used: ("Cognitive Rehabilitation" OR "Motor Rehabilitation" OR "CAREN" or "Computer-Assisted Rehabilitation Environment") AND ("Virtual Reality" OR "Rehab"). EVIDENCE SYNTHESIS: From the assessed studies, only seven met the inclusion criteria: 1) one study concerned cognitive rehabilitation in patients suffering from Parkinson's Disease (PD); 2) one was on the usability of CAREN in PD patients; 3) two studies related to the influence of emotional components to CAREN rehabilitation; 4) three studies were related to motor rehabilitation using CAREN, and involved individuals with PD, Multiple Sclerosis, TBI, respectively. Generally, the few assessed studies demonstrate that CAREN is a safe and potentially effective tool to treat different symptoms (including gait and vestibular disturbances, executive function, depressive mood, and anxiety) in patients with different neurological disorders. CONCLUSIONS: The reviewed literature indicated the potential use of CAREN in improving motor and cognitive skills with conflicting results on emotional aspects. However, since the data comes from few and small sample size studies, further research is needed to confirm the effectiveness of the tool in neurorehabilitation.

Effect of aquatic exercise programs according to the International Classification of Functionality, Disability and Health domains in individuals with Parkinson's disease: a systematic review and meta-analysis with GRADE quality assessment.

PURPOSE: To investigate the effects of aquatic exercise programs (AEP) in body structure and function, activity, and participation outcomes in individuals with Parkinson's disease (PD) with mild to moderate disability levels. METHODS: Six databases were searched from inception until November 2022. Randomized clinical trials that used AEP alone, AEP combined and/or compared two types of AEP were included. The quality of evidence was assessed by the GRADE approach and the standardized mean differences (SMD) were calculated the meta-analysis. RESULTS: Twelve studies (n = 380) were included. AEP alone was superior to active control in improving body structure and function outcome: postural balance (low evidence, SMD = 0.47, p = 0.02). No statistically significant differences were found for the other body structure and function outcomes: lower limb muscle strength (p = 0.14) and depressive symptoms (p = 0.79), activity outcomes: mobility (p = 0.32) and participation outcomes: quality of life (p = 0.05). AEP combined showed no statistically significant difference for the outcomes of body structure and function: postural balance (p = 0.11) and activity: mobility (p = 0.21) when compared to active control. CONCLUSION: AEP showed positive effects on body structure and function outcome (postural balance) in individuals with PD with mild to moderate disability levels while, no significant improvements were noticed for activity and participation outcomes.IMPLICATIONS FOR REHABILITATIONOur findings indicate that aquatic exercise programs (AEP) lead to significant improvements on body structure and function (i.e., postural balance) in individuals with Parkinson's disease (PD).The AEP evaluated in this study implemented postural balance, gait, single and double training, as well as aerobic exercises, trunk mobility exercises, and Ai Chi.The average duration, frequency, and total time implemented were 50 minutes, three times a week, for seven weeks, respectively.Considering the potential benefits identified in this study, AEP can be recommended as an adjunct treatment strategy for individuals with PD.Additionally, the use of the International Classification of Functionality, Disability and Health on the development of rehabilitation treatment plans is advised.

Video See-Through Pipelines for Virtual Reality Headsets and their Impact on Gait.

This study investigated the impact of different video see-through pipelines in virtual reality on gait. A mobility task was conducted with healthy participants to evaluate the gait adaptions using different video see-through pipelines. The gait parameters observed for this study were stride length, maximum toe clearance and walking speed. The results showed an impact on gait where the gait parameters were reduced when participants used a high latency and restricted field of view pipeline. However, when participants used a pipeline with low latency and a field of view closer to normal vision, less impact on gait was achieved. As virtual reality poses a promising future for gait rehabilitation in patients with Parkinson's disease, this result highlights the need to carefully consider the video see-through pipeline and display characteristics when considering its use for gait rehabilitation or mobility studies in general.Clinical relevance- This study demonstrates the impact of virtual reality systems on gait using different video see- through pipelines during a mobility task. This may be useful for clinicians who use virtual reality in gait rehabilitation and aid them in choosing the most suitable virtual reality system for therapy.

Laser-light Visual Cueing Shoes with Foot Pressures and Inertial Sensing for Individuals with Parkinson's Disease.

Gait disorder is a core problem in individuals with Parkinson's disease (PD), including bradykinesia, shuffling steps, festinating gait, and freeze of gait (FOG). Laser-light visual cueing has been demonstrated to be efficient in the mediation of gaits and the reduction in number of FOG episodes. However, previous approaches commonly adopted independent controls of visual cueing on left and right sides which was prone to produce two cues while individual was not in normal walking. In this study, we developed laser-light visual shoes which produced interlaced visual cues for left and right feet in a manner of one-side cueing at a time, solving the aforementioned problem. With parallel measurement of foot inertial data and foot pressures in each shoe, our results showed that the proposed visual cueing made PD individuals in the on-medication condition walk with a longer stance and swing times, that is, they walked more carefully and stable. The proposed approach can also be used to study kinematic and kinetic characteristics of gaits in the off-medication condition to clarify the mediation of visual cueing on motor control of PD individuals.Clinical Relevance- This demonstrates the effect of laser-light visual cueing on gaits in individuals with Parkinson's disease.

Auditory cueing strategy for stride length and cadence modification: a feasibility study with healthy adults.

People with Parkinson's Disease experience gait impairments that significantly impact their quality of life. Visual, auditory, and tactile cues can alleviate gait impairments, but they can become less effective due to the progressive nature of the disease and changes in people's motor capability. In this study, we develop a human-in-the-loop (HIL) framework that monitors two key gait parameters, stride length and cadence, and continuously learns a person-specific model of how the parameters change in response to the feedback. The model is then used in an optimization algorithm to improve the gait parameters. This feasibility study examines whether auditory cues can be used to influence stride length in people without gait impairments. The results demonstrate the benefits of the HIL framework in maintaining people's stride length in the presence of a secondary task.Clinical relevance- This paper proposes a gait rehabilitation framework that provides a personalized cueing strategy based on the person's real-time response to cues. The proposed approach has potential application to people with Parkinson's Disease.

Immediate Effects of Lower Limb Sensory Simulation Using Smart Socks to Stabilize Gait in People with Parkinson's Disease.

People with Parkinson's disease (PD) experience gait impairment that can lead to falls and poor quality of life. Here we investigate the feasibility of using smart socks to stimulate the lower limbs of people with PD to reduce excessive step time variability during walking. We hypothesised that rythmic excitation of lower limb afferents, matched to a participant's comfortable pace, would entrain deficient neuro-muscular signals resulting in improved gait. Five people with mild to moderate PD symptoms (70 ± 9 years) were tested on medication before and after a 30-minute familierization session. Paired t-tests and Cohen's d were used to assess gait changes and report effect sizes. Participant experiences were recorded through structured interviews. Lower limb stimulation resulted in an acute 15% increase in gait speed (p=0.006, d=0.62), an 11% increase in step length (p=0.04, d=0.35), a 44% reduction in step time variability (p=0.03, d=0.91), a 22% increase in perceived gait quality (p=0.04, d=1.17), a 24% reduction in mental effort to walk (p=0.02, d=0.79) and no statistical difference for cadence (p=0.16). Participants commented positively on the benefit of stimulation during training but found that stimulation could be distracting when not walking and the socks hard to put on. While the large effects for step time variability and percieved gait quality (Cohen's d > 0.8) are promising, limitations regarding sample size, potential placebo effects and translation to the home environment should be addressed by future studies.Clinical Relevance- This study demonstrates the feasibility of using smart stimulating socks to reduce excessive step time variability in people with PD. As step time variability is a risk factor for falls, the use of smart textiles to augment future rehabilitation programs warrants further investigation.

Four Days Are Enough to Provide a Reliable Daily Step Count in Mild to Moderate Parkinson's Disease through a Commercial Smartwatch.

Daily steps could be a valuable indicator of real-world ambulation in Parkinson's disease (PD). Nonetheless, no study to date has investigated the minimum number of days required to reliably estimate the average daily steps through commercial smartwatches in people with PD. Fifty-six patients were monitored through a commercial smartwatch for 5 consecutive days. The total daily steps for each day was recorded and the average daily steps was calculated as well as the working and weekend days average steps. The intraclass correlation coefficient (ICC) (3,k), standard error of measurement (SEM), Bland-Altman statistics, and minimum detectable change (MDC) were used to evaluate the reliability of the step count for every combination of 2-5 days. The threshold for acceptability was set at an ICC ≥ 0.8 with a lower bound of CI 95% ≥ 0.75 and a SAM < 10%. ANOVA and Mann-Whitney tests were used to compare steps across the days and between the working and weekend days, respectively. Four days were needed to achieve an acceptable reliability (ICC range: 0.84-0.90; SAM range: 7.8-9.4%). In addition, daily steps did not significantly differ across the days and between the working and weekend days. These findings could support the use of step count as a walking activity index and could be relevant to developing monitoring, preventive, and rehabilitation strategies for people with PD.

Effects of overground gait training assisted by a wearable exoskeleton in patients with Parkinson's disease.

BACKGROUND: In the recent past, wearable devices have been used for gait rehabilitation in patients with Parkinson's disease. The objective of this paper is to analyze the outcome of a wearable hip orthosis whose assistance adapts in real time to the patient's gait kinematics via adaptive oscillators. In particular, this study focuses on a metric characterizing natural gait variability, i.e., the level of long-range autocorrelations (LRA) in series of stride durations. METHODS: Eight patients with Parkinson's disease (Hoehn and Yahr stages 1[Formula: see text]2.5) performed overground gait training three times per week for four consecutive weeks, assisted by a wearable hip orthosis. Gait was assessed based on performance metrics such as the hip range of motion, speed, stride length and duration, and the level of LRA in inter-stride time series assessed using the Adaptive Fractal Analysis. These metrics were measured before, directly after, and 1 month after training. RESULTS: After training, patients increased their hip range of motion, their gait speed and stride length, and decreased their stride duration. These improvements were maintained 1 month after training. Regarding long-range autocorrelations, the population's behavior was standardized towards a metric closer to the one of healthy individuals after training, but with no retention after 1 month. CONCLUSION: This study showed that an overground gait training with adaptive robotic assistance has the potential to improve key gait metrics that are typically affected by Parkinson's disease and that lead to higher prevalence of fall.

An integrated review of music cognition and rhythmic stimuli in sensorimotor neurocognition and neurorehabilitation.

This work reviews the growing body of interdisciplinary research on music cognition, using biomechanical, kinesiological, clinical, psychosocial, and sociological methods. The review primarily examines the relationship between temporal elements in music and motor responses under varying contexts, with considerable relevance for clinical rehabilitation. After providing an overview of the terminology and approaches pertinent to theories of rhythm and meter from the musical-theoretical and cognitive fields, this review focuses on studies on the effects of rhythmic sensory stimulation on gait, rhythmic cues' effect on the motor system, reactions to rhythmic stimuli attempting to synchronize mobility (i.e., musical embodiment), and the application of rhythm for motor rehabilitation for individuals with Parkinson's disease, stroke, mild cognitive impairment, Alzheimer's disease, and other neurodegenerative or neurotraumatic diseases. This work ultimately bridges the gap between the musical-theoretical and cognitive science fields to facilitate innovative research in which each discipline informs the other.

Efficacy of non-immersive virtual reality-based telerehabilitation on postural stability in Parkinson's disease: a multicenter randomized controlled trial.

BACKGROUND: The implementation of regular prolonged, and effective rehabilitation in people with Parkinson's disease is essential for ensuring a good quality of life. However, the continuity of rehabilitation care may find barriers related to economic, geographic, and social issues. In these scenarios, telerehabilitation could be a possible solution to guarantee the continuity of care. AIM: To investigate the efficacy of non-immersive virtual reality-based telerehabilitation on postural stability in people with Parkinson's disease, compared to at-home self-administered structured conventional motor activities. DESIGN: Multicenter randomized controlled trial. SETTING: Five rehabilitation hospitals of the Italian Neuroscience and Rehabilitation Network. POPULATION: Individuals diagnosed with Parkinson's disease. METHODS: Ninety-seven participants were randomized into two groups: 49 in the telerehabilitation group (non-immersive virtual reality-based telerehabilitation) and 48 in the control group (at-home self-administered structured conventional motor activities). Both treatments lasted 30 sessions (3-5 days/week for, 6-10 weeks). Static and dynamic balance, gait, and functional motor outcomes were registered before and after the treatments. RESULTS: All participants improved the outcomes at the end of the treatments. The primary outcome (mini-Balance Evaluation Systems Test) registered a greater significant improvement in the telerehabilitation group than in the control group. The gait and endurance significantly improved in the telerehabilitation group only, with significant within-group and between-group differences. CONCLUSIONS: Our results showed that non-immersive virtual reality-based telerehabilitation is feasible, improves static and dynamic balance, and is a reasonably valuable alternative for reducing postural instability in people with Parkinson's disease. CLINICAL REHABILITATION IMPACT: Non-immersive virtual reality-based telerehabilitation is an effective and well-tolerated modality of rehabilitation which may help to improve access and scale up rehabilitation services as suggested by the World Health Organization's Rehabilitation 2030 agenda.

Estimulación cerebral profunda subtalámica en un caso de enfermedad de Parkinson idiopática y esquizofrenia / Subthalamic deep brain stimulation in a case of idiopathic Parkinson’s disease and schizophrenia

Introducción La enfermedad de Parkinson (EP) y la esquizofrenia pueden coexistir. Los antipsicóticos bloquean los receptores D2 estriados, lo que inevitablemente agrava las manifestaciones de la EP. Caso clínico Presentamos el caso de un paciente con enfermedad de Parkinson idiopática y esquizofrenia, con pobre tolerancia a dosis mínimas de levodopa, que presentó una gran mejoría tras la estimulación cerebral profunda subtalámica bilateral (ECP-NST). La ECP-NST se consideró aquí, debido a la gravedad de este caso particular, como la única posibilidad de lograr una mejoría motora. Conclusiones El diagnóstico de EP idiopática se confirmó pese al tratamiento antidopaminérgico. La ECP-NST puede considerarse como una opción de tratamiento para las manifestaciones de la EP invalidantes, siempre y cuando la selección del paciente sea cuidadosa. (AU)

Introduction. Parkinson’s disease (PD) and schizophrenia can coexist. Antipsychotics block striatal D2 receptors, which inevitably aggravates the manifestations of PD.Case report. We report the case of a male patient with idiopathic Parkinson’s disease and schizophrenia, with poor tolerance to minimal doses of levodopa, who underwent a dramatic improvement after bilateral subthalamic deep brain stimulation (DBS-STN). DBS-STN was taken into consideration here, due to the severity of this particular case, as the only possible way to achieve motor improvement.Conclusions. The diagnosis of idiopathic PD was confirmed despite antidopaminergic treatment. DBS-STN can be considered a treatment option for disabling manifestations of PD, provided that a careful selection of patients is carried out. (AU)

Association of activities of daily living, mobility and balance ability, and symptoms of Parkinson's disease with the masses and amounts of intramuscular non-contractile tissue of the trunk and lower extremity muscles in patients with Parkinson's disease.

PURPOSE: We examined the association of activities of daily living (ADL), mobility and balance ability, and symptoms of Parkinson's disease (PD) with the masses and amounts of intramuscular non-contractile tissue of the trunk and lower extremity muscles in patients with PD. METHODS: The subjects were 11 community-dwelling patients with PD. ADL were assessed using the Functional Independence Measure. Mobility capacity was assessed based on measurement of maximal walking speed and timed up-and-go time, while balance ability was evaluated based on measurement of one-legged stance time. The symptoms of PD were assessed based on measurement of the Hoehn and Yahr stage and Unified Parkinson's Disease Rating Scale. Muscle thickness (MT) and echo intensity (EI) of the trunk and lower extremity muscles were also measured using an ultrasound imaging device. RESULTS: Partial correlation analysis revealed an association between reduced ADL and increased EI of the lumbar erector spinae muscle; reduced mobility capacity and increased EI of the rectus abdominis and gluteus minimus muscles; and reduced balance ability and decreased MT of the lumbar erector spinae muscle and increased EI of the lumbar erector spinae, semitendinosus, and tibialis posterior muscles. Partial correlation analysis also showed an association between symptoms of severe PD and decreased MT of the tibialis anterior muscles and increased EI of the lumbar erector spinae, gluteus minimus, and tibialis posterior muscles. CONCLUSION: The properties of the trunk and lower extremity muscles may be critical for ADL, mobility and balance ability, and symptoms of PD in patients with PD.

Multicomponent and mat Pilates training increased gait speed in individuals with Parkinson's disease when walking and carrying a load: A single-blinded randomized controlled trial.

BACKGROUND AND PURPOSE: Gait disorders in individuals with Parkinson's disease (IwPD) are among the most disabling symptoms. Physical exercise has been proposed for the treatment of IwPD because it shows positive effects on gait variables. Given the importance of physical activity in the rehabilitation process of IwPD, the assessment of interventions to identify those most promising for improving or maintaining gait performance is of great relevance. Therefore, this study evaluated the effects of Mat Pilates Training (MPT) and Multicomponent Training (MCT) on the spatiotemporal variables of gait in situations of daily dual-task performance in IwPD. Gait analysis in a daily dual-task context allows the simulation of real-life conditions where individuals have a higher risk of falling than in single-task walking. METHODS: We conducted a single-blinded randomized controlled trial with 34 mild-to-moderate IwPD (Hoehn-Yahr stage 1-2). They were randomized to one of two interventions: MPT or MCT. All participants performed the training for 60 min, three times per week, for 20 weeks. Spatiotemporal gait variables were evaluated in a daily life situation to increase the ecological validity of the measurements, which included gait speed, stride time, double support time, swing time, and cadence. The individuals walked on a platform holding two bags with a load corresponding to 10% of their body mass. RESULTS: After the intervention, there was a significant improvement in gait speed in both groups: MPT (p = 0.047) and MCT (p = 0.015). The MPT group reduced the cadence (p = 0.005) and the MCT group increased the stride length (p = 0.026) after the intervention. DISCUSSION: Both groups had positive effects on gait speed with load transport resulting from the two proposed interventions. However, the MPT group showed a spatiotemporal adjustment of speed and cadence that can increase gait stability, which was not found in the MCT group.

Effect of Music Based Therapy Rhythmic Auditory Stimulation (RAS) Using Wearable Device in Rehabilitation of Neurological Patients: A Systematic Review.

(1) Background: Even though music therapy is acknowledged to have positive benefits in neurology, there is still a lack of knowledge in the literature about the applicability of music treatments in clinical practice with a neurological population using wearable devices. (2) Methods: a systematic review was conducted following PRISMA 2020 guidelines on the 29 October 2022, searching in five databases: PubMed, PEDro, Medline, Web of Science, and Science Direct. (3) Results: A total of 2964 articles were found, including 413 from PubMed, 248 from Web of Science, 2110 from Science Direct, 163 from Medline, and none from PEDro. Duplicate entries, of which there were 1262, were eliminated. In the first screening phase, 1702 papers were screened for title and abstract. Subsequently, 1667 papers were removed, based on population, duplicate, outcome, and poor study design. Only 15 studies were considered after 35 papers had their full texts verified. Results showed significant values of spatiotemporal gait parameters in music-based therapy rhythmic auditory stimulation (RAS), including speed, stride length, cadence, and ROM. (4) Conclusions: The current findings confirm the value of music-based therapy RAS as a favorable and effective tool to implement in the health care system for the rehabilitation of patients with movement disorders.

A systematic review and meta-analysis on the effect of virtual reality-based rehabilitation for people with Parkinson's disease.

BACKGROUND: Virtual reality (VR) is a promising solution for individuals with Parkinson's disease (PD) who experience symptoms that affect their daily activities and independence. Through VR-based rehabilitation, patients can improve their motor skills in a safe and stress-free environment, making it an attractive alternative to traditional in-person rehabilitation during the COVID-19 pandemic. This study aimed to provide the most recent and convincing evidence on the rehabilitative effects of VR technology compared with conventional treatments. METHODS: Two investigators systematically searched Embase, MEDLINE, CINAHL, PEDro, and the Cochrane Library from their inception until May 31, 2022, to identify randomized controlled trials (RCTs) comparing the effectiveness of VR training with that of conventional treatment for patients with PD. Studies were selected based on the patient, intervention, comparator, and outcome criteria and assessed for the risk of bias using the Cochrane tool. Meta-analysis was conducted by pooling mean differences with 95% confidence intervals. RESULTS: A total of 14 RCTs, involving 524 participants, were included in the meta-analysis. The results indicated that VR-based rehabilitation significantly improved balance function, as measured using the Berg balance scale (BBS) and activities-specific balance confidence. However, no statistically significant differences in gait ability, activities of daily living, motor function, and quality of life were observed between the experimental and control groups. Subgroup analysis revealed that combination therapy affected heterogeneity in the BBS analysis. Meta-regression analysis demonstrated a significant positive relationship, indicating that more recent studies have shown greater improvements in balance function. CONCLUSION: This study's findings suggest that VR-based rehabilitation is a promising intervention for improving balance function in patients for PD compared with conventional treatment, and recent research supports its efficacy. However, future research should focus on conducting long-term follow-up studies and developing standardized protocols to comprehensively establish this intervention's potential benefits.
