Does cybersickness affect virtual reality training using the Computer Assisted Rehabilitation Environment (CAREN)? Preliminary results from a case-control study in Parkinson's disease.

INTRODUCTION AND OBJECTIVE: This pilot study aimed to evaluate whether and to what extent cybersickness (CS) may affect a rehabilitation program using the Computer-assisted Rehabilitation Environment (CAREN), a virtual reality (VR) computer-assisted device for clinical rehabilitation. METHODS: The study was carried out on 30 subjects, 15 patients with Parkinson's Disease (PD) and 15 healthy controls (HC), which underwent a set of four exergames programmed by our team for PD rehabilitation training. RESULTS: All participants completed the Motion Sickness Susceptibility Questionnaire Short-form (MSSQ) before the training and the Motion Symptoms Assessment Questionnaire (MSAQ) immediately after a single CAREN session. Overall, mean MSAQ scores remained low after the session, suggesting that the users did not experience severe discomfort. We found no significant difference in MSAQ scores between the two groups, while there was a statistically significant difference for the subsection of MSAQ regarding the peripheral symptoms (i.e. sweating, cold sweating, feeling warm), which were higher in HC. Moreover, the results highlighted some correlation between MSSQ and MSAQ. Gastrointestinal symptoms in PD, as well as MSSQ and sopite-related symptoms in HC, were also correlated with susceptibility to CS. CONCLUSIONS: As CS is rarely reported after CAREN, this and similar devices may be considered comfortable and safe for patients' rehabilitation involving VR training, including PD persons.

How personality traits affect functional outcomes in patients with multiple sclerosis: A scoping review on a poorly understood topic.

Personality is an important variable when explaining individual differences in disease acceptance, coping styles and psychological well-being. Personality changes, such as social inadequacy, disinhibition, apathy, emotional lability, and impulsivity, have been reported in many patients with multiple sclerosis (MS). This review sought to assess the role of personality traits in people with MS, focusing on how this may affect the patient's outcome. Studies were identified by searching on PubMed, Web Of Science and Cochrane databases. Our review shows that the personality traits commonly found in MS are often dysfunctional. In particular, it has been suggested that people with MS present with lower levels of conscientiousness, extraversion and agreeableness, as well as higher levels of neuroticism than healthy controls. These personality traits negatively affect cognitive domains, mood, and psychological well-being. As personality may affect the clinical manifestations and disabilities of patients with MS, personality assessment should be an integral part of the management of the disease, in order to achieve better functional outcomes.

An integrative cognitive rehabilitation using neurologic music therapy in multiple sclerosis: A pilot study.

BACKGROUND: Multiple sclerosis (MS) is a demyelinating disease, affecting both the sensorimotor and cognitive systems. The typical pattern of cognitive impairment includes reduced speed of information processing, decreased phonological and semantic speech fluency, deficits in verbal and visual episodic memory, as well as attention and executive dysfunctions. We aimed to investigate the influence of the neurologic music therapy (NMT) on mood, motivation, emotion status, and cognitive functions in patients with MS. METHODS: Thirty patients with MS were randomly divided in 2 groups: the control group (CG) undergoing conventional cognitive rehabilitation (CCR), 6 times a week for 8 weeks, and the experimental group (EG) undergoing CCR 3 times a week for 8 weeks plus NMT techniques, performed 3 times a week for 8 weeks. All the participants were submitted to the same amount of treatment. Each patient was evaluated before (baseline: T0) and immediately after the end of each training (T1). MAIN OUTCOMES MEASURES: We used as main outcome measure: the brief repeatable battery of neuropsychological test to assess various cognitive abilities; and the multiple sclerosis quality of life-54 (MSQoL-54). RESULTS: Both the groups benefit from 8 weeks of CR. In particular, the EG got better results in cognitive function, with regard to selective reminding test long term storage (P < .000), long term retrieval (P = .007), and delayed recall of the 10/36 spatial recall test (P = .001), as compared with the CG. Moreover, the improvement in emotional status, motivation, mood and quality of life (with regard to the mental component; P < .000) was more evident in the EG. CONCLUSIONS: NMT could be considered a complementary approach to enhance CCR in patients affected by MS.

Do patients with PD benefit from music assisted therapy plus treadmill-based gait training? An exploratory study focused on behavioral outcomes.

Purpose: Parkinson's disease (PD) is the second most common age-related neurodegenerative disorder, presenting not only with motor symptoms (resting tremor, bradykinesia, and muscular rigidity), but also with cognitive and behavioral problems that need to be addressed in a rehabilitation setting. Aim of the study was to evaluate the effects of a combined rehabilitative approach, using gait training coupled to music-based therapy, on cognitive and behavioral function in a sample of patients with PD.Materials and Methods: Forty patients, meeting the inclusion criteria, were enrolled in this study and were randomly divided into two groups. The control group (CG) underwent traditional over ground gait training, whilst the experimental group (EG) underwent gait training with the Biodex Gait Trainer 3 (a treadmill integrated with music therapy). Each subject was evaluated at baseline (T0) and after the training (T1), using specific neuropsychological and motor function tests.Results: The EG presented higher outcomes scores concerning mood and quality of life in all subscales of Psychological General Well-Being Index (i.e. anxiety, depression, health, vitality and positivity) and subscales of Brief-COPE, with regard to behavioral disengagement, positive reframing, planning, acceptance and use of emotional support, as compared to the CG. Moreover, a significant improvement in motor functioning, with regard to static and dynamic balance, was found in the EG.Conclusion: Music-based gait training rehabilitation may be considered an effective strategy to improve behavioral performances, coping strategies and rehabilitation outcomes in patients with PD.

The cortico-rubral and cerebello-rubral pathways are topographically organized within the human red nucleus.

The Red Nucleus (RN) is a large nucleus located in the ventral midbrain: it is subdivided into a small caudal magnocellular part (mRN) and a large rostral parvocellular part (pRN). These distinct structural regions are part of functionally different networks and show distinctive connectivity features: the mRN is connected to the interposed nucleus, whilst the pRN is mainly connected to dentate nucleus, cortex and inferior olivary complex. Despite functional neuroimaging studies suggest RN involvement in complex motor and higher order functions, the pRN and mRN cannot be distinguished using conventional MRI. Herein, we employ high-quality structural and diffusion MRI data of 100 individuals from the Human Connectome Project repository and constrained spherical deconvolution tractography to perform connectivity-based segmentation of the human RN. In particular, we tracked connections of RN with the inferior olivary complex, the interposed nucleus, the dentate nucleus and the cerebral cortex. We found that the RN can be subdivided according to its connectivity into two clusters: a large ventrolateral one, mainly connected with the cerebral cortex and the inferior olivary complex, and a smaller dorsomedial one, mainly connected with the interposed nucleus. This structural topography strongly reflects the connectivity patterns of pRN and mRN respectively. Structural connectivity-based segmentation could represent a useful tool for the identification of distinct subregions of the human red nucleus on 3T MRI thus allowing a better evaluation of this subcortical structure in healthy and pathological conditions.
