RESUMEN
The assessment of cognitive deficits is pivotal for diagnosis and management in patients with parkinsonisms. Low levels of correspondence are observed between evaluations assessed with screening cognitive tests in comparison with those assessed with in-depth neuropsychological batteries. A new tool, we named CoMDA (Cognition in Movement Disorders Assessment), was composed by merging Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA), and Frontal Assessment Battery (FAB). In total, 500 patients (400 with Parkinson's disease, 41 with vascular parkinsonism, 31 with progressive supranuclear palsy, and 28 with multiple system atrophy) underwent CoMDA (level 1-L1) and in-depth neuropsychological battery (level 2-L2). Machine learning was developed to classify the CoMDA score and obtain an accurate prediction of the cognitive profile along three different classes: normal cognition (NC), mild cognitive impairment (MCI), and impaired cognition (IC). The classification accuracy of CoMDA, assessed by ROC analysis, was compared with MMSE, MoCA, and FAB. The area under the curve (AUC) of CoMDA was significantly higher than that of MMSE, MoCA and FAB (p < 0.0001, p = 0.028 and p = 0.0007, respectively). Among 15 different algorithmic methods, the Quadratic Discriminant Analysis algorithm (CoMDA-ML) showed higher overall-metrics performance levels in predictive performance. Considering L2 as a 3-level continuous feature, CoMDA-ML produces accurate and generalizable classifications: micro-average ROC curve, AUC = 0.81; and AUC = 0.85 for NC, 0.67 for MCI, and 0.83 for IC. CoMDA and COMDA-ML are reliable and time-sparing tools, accurate in classifying cognitive profile in parkinsonisms.This study has been registered on ClinicalTrials.gov (NCT04858893).
RESUMEN
Introduction: Dopaminergic medications can trigger impulsive-compulsive behaviors (ICBs) in pre-disposed patients with Parkinson's disease (PD), but what this implies on a neurocognitive level is unclear. Previous findings highlighted potentially exacerbated incentive motivation (willingness to work for rewards) and choice impulsivity (preferring smaller, immediate rewards over larger, delayed rewards) in PD patients with ICBs (PD + ICBs). Methods: To deeply understand this evidence, we studied 24 PD + ICBs and 28 PD patients without ICBs (PD-ICBs). First of all, patients underwent the assessment of impulsivity traits, mood, anxiety, and addiction condition. We further administered robust objective and subjective measures of specific aspects of motivation. Finally, we explored whether these processes might link to any heightened antisocial behavior (aggression and risky driving) in PD + ICBs. Results: High levels of positive urgency trait characterized PD + ICBs. They choose to exert more effort for rewards under the conditions of low and medium reward probability and as reward magnitude increases. Findings on choice impulsivity show a great tendency to delay discounting in PD + ICBs, other than a high correlation between delay and probability discounting. In addition, we found what appears to be the first evidence of heightened reactive aggression in PD patients with ICBs. Exacerbated incentive motivation and delay discounting trended toward positively predicting reactive aggression in PD + ICBs. Discussion: Our promising results suggest that there might be immense value in future large-scale studies adopting a transdiagnostic neurocognitive endophenotype approach to understanding and predicting the addictive and aggressive behaviors that can arise from dopaminergic medication in PD.
RESUMEN
BACKGROUND: Optimal management in expert centers for Parkinson's disease (PD) usually involves pharmacological and non-pharmacological interventions, delivered by a multidisciplinary approach. However, there is no guideline specifying how this model should be organized. Consequently, the nature of multidisciplinary care varies widely. OBJECTIVE: To optimize care delivery, we aimed to provide recommendations for the organization of multidisciplinary care in PD. METHODS: Twenty expert centers in the field of multidisciplinary PD care participated. Their leading neurologists completed a survey covering eight themes: elements for optimal multidisciplinary care; team members; role of patients and care partners; team coordination; team meetings; inpatient versus outpatient care; telehealth; and challenges towards multidisciplinary care. During a consensus meeting, outcomes were incorporated into concept recommendations that were reviewed by each center's multidisciplinary team. Three patient organizations rated the recommendations according to patient priorities. Based on this feedback, a final set of recommendations (essential elements for delivery of multidisciplinary care) and considerations (desirable elements) was developed. RESULTS: We developed 30 recommendations and 10 considerations. The patient organizations rated the following recommendations as most important: care is organized in a patient-centered way; every newly diagnosed patient has access to a core multidisciplinary team; and each team has a coordinator. A checklist was created to further facilitate its implementation. CONCLUSION: We provide a practical tool to improve multidisciplinary care for persons with PD at the organizational level. Future studies should focus on implementing these recommendations in clinical practice, evaluating their potential applicability and effectiveness, and comparing alternative models of PD care.

OBJECTIVE: Freezing of gait (FoG) is a debilitating problem in patients with PD. The multifactorial pathogenesis of FoG remains poorly understood. We aimed to find which factors are most strongly associated with the occurrence of FoG. METHODS: Three hundred five PD patients were enrolled and subdivided according to the presence (FoG +, n = 128) or absence (FoG-, n = 177) of FoG. Several clinical, functional, and neuropsychological data were collected and compared between groups. The association between the probability of presence of FoG and possible explanatory variables was assessed by logistic regression analysis. RESULTS: FoG + patients were younger at the diagnosis (p = 0.04), and their mean daily dose of dopaminergic drugs (p < 0.0001) was higher in comparison with FoG- patients. FoG + patients get worse in Frontal Assessment Battery (p = 0.005), had higher scores in Apathy Evaluation Scale (p = 0.03), and were much more impaired on Wisconsin Card Sorting Test (WCST) (p = 0.018), Trail Making Test A (p = 0.0013), and Ray Auditory Verbal Learning Test (p = 0.012). Levodopa equivalent dose, age (direct), age at disease onset (inverse), and WCST were significant predictors of FoG (p = 0.01, p = 0.0025, p = 0.0016, and p = 0.029, respectively). CONCLUSION: FoG + patients show more deficits in executive functions and in motivation. The main explanatory variables of FoG occurrence are levodopa equivalent dose, age, age at disease onset, and WCST. These data suggest that a specific involvement of frontal cortical circuits in PD is responsible for certain cognitive-behavioral alterations related to the occurrence of FoG.
RESUMEN
BACKGROUND: Hand functionality and finger dexterity are impaired in patients with Parkinson's disease (PD). These disturbances lead to a dependency in activities of daily living (ADL) and poor quality of life (QoL). OBJECTIVE: We aimed to evaluate whether a specific occupational therapy (OT) program is effective in improving finger and hand dexterity and its impact on ADL in PD patients. METHODS: We retrospectively studied PD patients, hospitalized for a 4-week multidisciplinary intensive rehabilitation treatment (MIRT) between January 2015 and June 2018. All patients underwent 1 h/day OT treatment, 5 days a week. The primary outcome measure was the O'Connor finger dexterity test; secondary outcome measures were the Minnesota dexterity test, UPDRS II, and Self-Assessment Parkinson's Disease Disability Scale (SPDDS). These measures were assessed at admission (T0) and discharge (T1). RESULTS: Based on the Hoehn and Yahr scale (H&Y), patients were divided into two groups: 262 subjects in H&Y stage <3 (early-stage PD patients) and 220 in H&Y stage ≥3 (medium-advanced stage PD patients). As expected, at baseline, all measures were worse in higher H&Y stages. After treatment, both groups experienced significant improvements in all outcomes. Significant differences between early-stage and medium-advanced stage PD patients were observed only for the changes in UPDRS II, with a better improvement in patients in H&Y stage ≥3. CONCLUSIONS: We showed that PD patients who underwent a rehabilitation protocol including OT experienced improvements in finger dexterity and hand functionality. Our results underline the relevance of OT in improving autonomy and QoL in PD patients.
RESUMEN
Movement is accompanied by modulation of oscillatory activity in different ranges over the sensorimotor areas. This increase is more evident in normal subjects and less in patients with Parkinson's Disease (PD), a disorder associated with deficits in the formation of new motor skills. Here, we investigated whether such EEG changes improved in a group of PD patients, after two different treatments and whether this relates to performance. Subjects underwent either a session of 5 Hz repetitive Transcranial Magnetic Stimulation (rTMS) over the right posterior parietal cortex or a 4-week Multidisciplinary Intensive Rehabilitation Treatment (MIRT). We used a reaching task with visuo-motor adaptation to a rotated display in incremental 10° steps up to 60°. Retention of the learned rotation was tested before and after either intervention over two consecutive days. High-density EEG was recorded throughout the testing. We found that patients adapted their movements to the rotated display similarly to controls, although retention was poorer. Both rTMS and MIRT lead to improvement in retention of the learned rotation. Mean beta modulation levels changed significantly after MIRT and not after rTMS. These results suggest that rTMS produced local improvement reflected in enhanced short-term skill retention; on the other hand, MIRT determined changes across the contralateral sensorimotor area, reflected in beta EEG changes.

Background: constipation is one of the most common and disabling non-motor symptoms of Parkinson Disease (PD) and Parkinsonisms (PS). Few studies evaluate the difference of prevalence between PD and PS and the cause leading to a severe constipation in this diseases. Objective: Aim of our study is to evaluate the prevalence of constipation in a population of patients with PD and PS and to evaluate which factors influence the development of severe constipation. Methods: Two hundred and fifty outpatients with PD and 39 with PS were enrolled. Sixty five age-matched healthy subjects served as control. Constipation was assessed using the "Constipation Scoring System" (CSS). All patients underwent a global clinical, functional and neuropsychological assessment including: Unified Parkinson's disease Rating Scale (UPDRS), 6-min Walk Test (6MWT), and Mini-Mental State Examination (MMSE). Results: Data confirm the high prevalence of constipation among patients with PD and PS. Severe constipation affects much more patients with PS. A significant association between total CSS and age, H and Y stage, 6MWT, MMSE, total UPDRS, and UPDRS III was found in PD. In PS patients total CSS was associated with age, 6MWT, total UPDRS, and UPDRS III. Multivariable regression analysis showed that the only variables significantly and independently associated with total CSS in PD patients were age and total UPDRS, both with direct relationship. Conclusions: The reduction of motor performance seems to be the primary cause for developing severe constipation in PD and PS patients. These data suggest that maintain a good quality of gait and endurance may be helpful to reduce the risk of constipation.
RESUMEN
OBJECTIVE: We evaluated the efficacy of muscle-targeted nutritional support on the functional outcomes of multidisciplinary intensive rehabilitation treatment (MIRT) in patients with Parkinson disease (PD) or parkinsonism. METHODS: We conducted a pragmatic, bicentric, randomized (1:1), assessor-blind controlled trial (Protein, Leucine and Vitamin D Enhancing Rehabilitation [PRO-LEADER]; April 2017 to January 2018) in cognitively intact patients with PD or parkinsonism and undergoing a 30-day MIRT. Patients (n = 150) received a standard hospital diet with or without a whey protein-based nutritional supplement enriched with leucine and vitamin D twice daily. The primary efficacy endpoint was the increase in the distance walked during a 6-minute walking test (6MWT). Secondary endpoints were changes in 4-meter walking speed, Timed Up and Go test (TUG), Berg balance scale, handgrip strength, Self-assessment Parkinson's Disease Disability Scale, body weight, and skeletal muscle mass (SMM). RESULTS: Nutritional support resulted in greater increase in the distance walked during 6MWT (mean 69.6 meters [95% confidence interval (CI) 60.7-78.6]) than no support (51.8 meters [95% CI 37.0-66.7]): center-adjusted mean difference, 18.1 meters (95% CI 0.9-35.3) (p = 0.039). Further adjustment for changes in dopaminergic therapy and SMM yielded consistent results: mean difference, 18.0 meters (95% CI 0.7-35.2) (p = 0.043). A meaningful effect was also found for the following secondary endpoints: 4-meter walking speed (p = 0.032), TUG (p = 0.046), SMM, and SMM index (p = 0.029). Six patients discontinued the nutritional therapy due to mild side effects. CONCLUSION: The consumption of a whey protein-based nutritional formula enriched with leucine and vitamin D with MIRT improved lower extremity function and preserved muscle mass in patients with PD or parkinsonism.Clinicaltrials.gov IDENTIFIER: NCT03124277. CLASSIFICATION OF EVIDENCE: This study provides Class I evidence that for patients with parkinsonism undergoing intensive rehabilitation, a whey protein-based nutritional formula enriched with leucine and vitamin D increased distance walked on the 6MWT.

BACKGROUND: the social impact of Parkinson's is difficult to capture in quantitative research given the condition's variable presentation, so qualitative research is needed to support a person-centred approach. AIMS: to describe how people with Parkinson's experience living with their condition over time. METHODS: 27 audio-recorded verbatim-transcribed interviews were analysed through the grounded theory method. FINDINGS: past, present and future were the core categories that emerged. Past is the dimension of regretted memories of past life overturned by the communication of diagnosis. Present is the time dimension in which patients concretely experience the hindrances associated with the condition (loss of autonomy, submissive acceptance and social embarrassment), and the resources (search for autonomy, serene or in-progress acceptance, and social support). Future is characterised by both positive visions of tomorrow and negative ones (worry, resignation, denial). CONCLUSION: these results, highlighting what living with Parkinson's means over time, may contribute to a better tailoring of nursing practice to the person's needs and rhythm, in a perspective of continuous adaptation.

BACKGROUND: Freezing of gait (FOG) is one of the most disabling symptoms of Parkinson disease (PD). Different land-based rehabilitation approaches based on motor and cognitive strategies can be effective in treating FOG. Although there are data about the efficacy of aquatic therapy in ameliorating this phenomenon, no study has explored the combined effect of land-based therapies plus aquatic therapy in patients with PD who have FOG. OBJECTIVE: The objective was to investigate the effectiveness of a multidisciplinary, intensive, motor-cognitive rehabilitation treatment (MIRT) in improving FOG and whether implementation with aquatic therapy (MIRT-AT) adds further benefits. DESIGN: The design consisted of a single-blind, parallel-group, 1:1 allocation ratio, randomized trial. SETTING: The Department of Parkinson Disease, Movement Disorders and Brain Injury Rehabilitation at "Moriggia-Pelascini" Hospital (Gravedona ed Uniti, Como, Italy) was used as the setting. PARTICIPANTS: Sixty hospitalized patients with PD who had FOG in Hoehn and Yahr stage 2 or 5-3 were included. INTERVENTION: Sixty patients with PD + FOG were randomly assigned to 2 groups: 30 underwent a 4-week MIRT and 30 underwent a 4-week MIRT-AT. MEASUREMENTS: The primary outcome measure was the Freezing of Gait Questionnaire; secondary outcome measures were total Unified Parkinson Disease Rating Scale (UPDRS), UPDRS II, UPDRS III, Berg Balance Scale, Timed Up and Go Test, and 6-Minute Walk Test. These measures were assessed both at admission and discharge. RESULTS: Participants in the 2 groups had similar age, sex distribution, Hoehn and Yahr stage, and most-affected side. At baseline, no difference in outcome measures was observed between the 2 groups. After treatment, a significant time effect was observed for all variables in both groups. No significant time × group interaction was observed. A between-group analysis showed nonsignificant differences between values at T1 and values at T0 for all variables. LIMITATIONS: The limitations were the lack of a control group and follow-up. CONCLUSIONS: We showed that a multidisciplinary, intensive, and goal-based rehabilitation treatment, such as MIRT, improves FOG in patients with PD. Although aquatic therapy could be considered a useful approach for treating FOG, it does not add further benefits to this kind of motor-cognitive rehabilitation.

Purpose: Early decannulation is considered a main rehabilitative goal in tracheostomized patients. Our aim is to evaluate whether a very early rehabilitation protocol helps to reduce the tracheostomy duration in patients affected by an Acquired Brain Injury (ABI). Methods: Data about consecutive tracheostomized patients admitted in our Neuro-Rehabilitation Unit (NRU) were retrospectively collected. We defined two groups: Early Rehabilitation Group patients came from our ICU, where they started the rehabilitative treatment; Delayed Rehabilitation Group patients arrived from external ICUs and started rehabilitation in our NRU. Primary outcome was the time from tracheostomy to decannulation. Secondary outcomes were: ICU length of stay, time from NRU admission to decannulation, Glasgow Coma Scale, Coma Recovery Scale revised and Levels of Cognitive Functioning scores at NRU discharge and the re-cannulation rate. Results: We enrolled 66 patients, 40 in the Early Rehabilitation Group and 26 in the Delayed Rehabilitation Group. 70% of patients for each group could be decannulated (p = 0.73) and were analyzed. Only one patient was re-cannulated. Early Rehabilitation Group showed a shorter tracheostomy duration (61.0 vs. 94.5 days, p = 0.013), a higher probability of occurrence of decannulation (p = 0.008) and a lower ICU length of stay (30.0 vs. 52.0 days, p = 0.001). The time to decannulation in NRU was similar between groups (30.0 vs. 45.50 days, p = 0.14). All the scale scores had a significant improvement in both groups (p < 0.0001 all). Conclusions: The present study shows that an early neuro-rehabilitation protocol helps to reduce the time to decannulation in tracheostomized patients affected by ABI.
RESUMEN
Parkinson's disease (PD) is characterized by motor and cognitive dysfunctions, affecting the motor behaviour. We summarize evidence that the interplay between motor and cognitive approaches is crucial in PD rehabilitation. Rehabilitation is complementary to pharmacological therapy and effective in reducing the PD disturbances, probably acting by inducing neuroplastic effects. The motor behaviour results from a complex integration between cortical and subcortical areas, underlying the motor, cognitive and motivational aspects of movement. The close interplay amongst these areas makes possible to learn, control and express habitual-automatic actions, which are dysfunctional in PD. The physiopathology of PD could be considered the base for the development of effective rehabilitation treatments. As the volitional action control is spared in early-medium stages of disease, rehabilitative approaches engaging cognition permit to achieve motor benefits and appear to be the most effective for PD. We will point out data supporting the relevance of targeting both motor and cognitive aspects in PD rehabilitation. Finally, we will discuss the role of cognitive engagement in motor rehabilitation for PD.

Dopaminergic medication can induce severe addictive behaviours (e.g., pathological gambling) in susceptible Parkinson's disease (PD) patients. It is still unknown which particular neurocognitive processes become exacerbated or dysfunctional in PD patients with addictive behaviours. We sought to systematically review the relevant literature to identity potential neurocognitive correlates of medication-induced addictive behaviours in PD. We framed our review around neurocognitive processes central to four dominant accounts of substance addiction: 'aberrant learning', 'incentive sensitization', 'impulsivity to compulsivity' and 'impaired response inhibition and salience attribution'. Searches of the PubMed and Scopus databases were completed on June 23, 2017. To be included, studies were required to involve: (a) medicated PD patients, without a history of deep brain stimulation, with and without addictive behaviours; (b) a reward-related or decision-making task; and (c) statistical comparison of addictive and non-addictive groups' 'on' medication performance on the task(s). Studies were summarised qualitatively with statistically significant (p<.05) group differences and effect sizes (Cohen's d) highlighted. 35 studies were included. Findings showed that the extant literature is highly heterogeneous. The domains of reward and punishment learning, reflection impulsivity and disadvantageous decision-making exemplify this. More homogeneity exists in domains in which (a) neurocognitive dysfunction is not apparent (motor control, cognitive/attentional flexibility and cognitive control) or (b) typical neurocognitive processes appear exacerbated by medication (reward motivation and choice impulsivity). Future large-scale neurocognitive studies are still required to develop our scientific understanding of addictive behaviours in PD and aid their clinical treatment and prediction.

BACKGROUND: Parkinsonian patients in advanced stages of disease suffer from many motor and non-motor symptoms, whose responsiveness to dopamine replacement therapy and deep brain stimulation is poor. It is necessary to find complementary strategies in order to improve the clinical conditions of patients in advanced Parkinson's disease (PD) stages. OBJECTIVE: We aimed to understand whether an inpatient, motor-cognitive, multidisciplinary, aerobic, intensive and goal-based rehabilitation treatment (MIRT), specifically designed for PD, is effective for patients in advanced stages of disease. METHODS: 638 Parkinsonian patients, hospitalized to undergo a 4-week MIRT, were retrospectively identified. According to the Hoehn & Yahr (H&Y) scale, 496 were in H&Y stage 3 and 142 in H&Y stage 4-5. Outcome measures included: Unified Parkinson's Disease Rating Scale (UPDRS), Berg Balance Scale (BBS), Timed Up and Go Test (TUG), Six Minute Walk Test (6MWT), and Parkinson's Disease Disability Scale (PDDS). RESULTS: At baseline all measures, except UPDRS IV, significantly worsened passing from H&Y stage 3 to H&Y stage 4-5 (p≤0.002 all). After rehabilitation all outcome measures significantly improved in both groups of patients (pâ<â0.0001 all). Comparing the amount of improvement in the two groups, significant differences were observed only for the changes in BBS and TUG (both pâ<â0.0001 after adjustment), with a better improvement in the H&Y stage 4-5 group. CONCLUSIONS: A multidisciplinary, motor-cognitive, intensive and goal-based rehabilitation treatment, such as MIRT, could be an effective complementary treatment in PD patients in advanced stages of disease.

OBJECTIVE: To evaluate whether a 4-week multidisciplinary, aerobic, motor-cognitive and intensive rehabilitation treatment (MIRT) improves the quality of life (QoL) of patients with Parkinson's disease (PD), in the short-term and long-term period. METHODS: This is a prospective, parallel-group, single-centre, single-blind, randomised clinical trial (ClinicalTrials.gov NCT02756676). 186 patients with PD, assigned to experimental group, underwent MIRT; conversely, 48 patients, assigned to control group, did not receive rehabilitation. Parkinson's Disease Questionnaire-39 was assessed 2 (T0), 10 (T1) and 18 (T2, only experimental group) weeks after the enrolment. We compared T1 versus T0 scores within subjects and delta scores (T1-T0) between subjects. To investigate the long-term effects, we compared T2 and T0 scores in the experimental group. RESULTS: At T0, no between-group differences in the Global Index Score (GBI) were observed (experimental group: 43.6±21.4, controls: 41.6±22.9, P=0.50). At T1, we did not find significant changes in controls (delta score: 1.2±9.9, P=0.23), and we found an improvement in GBI in the experimental group (delta score: -8.3±18.0, P<0.0001), significant also between subjects (P<0.0001). Comparing T2 versus T0 in the experimental group, the GBI maintained a significant improvement (delta score: -4.8±17.5, P<0.0001). CONCLUSIONS: A rehabilitation treatment such as MIRT could improve QoL in patients with PD in the short-term and long-term period. Even though the single-blind design and the possible role of the placebo effect on the conclusive results must be considered as limitations of this study, the improvement in outcome measure, also maintained after a 3-month follow-up period, suggests the effectiveness of MIRT on the QoL.

Background: Attention is crucial to voluntary perform actions in Parkinson's disease (PD), allowing patients to bypass the impaired habitual motor control. The asymmetrical degeneration of the dopaminergic system could affect the attentional functions. Objective: To investigate the relationship between the asymmetric dopaminergic degeneration and the attentional resources in Parkinsonian patients with right-side (RPD) and left-side (LPD) motor symptoms predominance. Methods: 50 RPD, 50 LPD, and 34 healthy controls underwent visual (V), auditory (A), and multiple choices (MC) reaction time (RTs) tasks. For PD patients, these tasks were performed before and after a 4-week intensive, motor-cognitive rehabilitation treatment (MIRT). The effectiveness of treatment was evaluated assessing Unified Parkinson's disease Rating Scale (UPDRS) III and Timed-up and Go Test (TUG). Results: RTs did not differ between PD patients and healthy controls. Before MIRT, no differences between LPD and RPD patients were observed in RTs (p = 0.20), UPDRS III (p = 0.60), and TUG (p = 0.38). No differences in dopaminergic medication were found between groups (p = 0.44 and p = 0.66 before and after MIRT, respectively). After MIRT, LPD patients showed a significant reduction in MC RTs (p = 0.05), V RTs (p = 0.02), and MC-V RTs. A significant association between changes in RTs and improvements in UPDRS III and TUG was observed in LPD patients. Conclusion: attention does not differ among RPD patients, LPD patients and healthy controls. Only LPD patients improved their performances on attentional tasks after MIRT. We argue that the increased early susceptibility of the left nigrostriatal system to degeneration affects differently the cognitive modifiability and the neuroplastic potential. Our results could provide insight into new therapeutic approaches, highlighting the importance to design different treatments for RPD patients and LPD patients.
RESUMEN
OBJECTIVE: To compare the effects on gait and balance of aquatic physiotherapy versus on-land training, in the context of an inpatient rehabilitation treatment tailored for peripheral neuropathies. DESIGN: Parallel-group, single-center, single-blind randomized controlled trial. SUBJECTS AND SETTING: Consecutive patients affected by peripheral neuropathy admitted in our Neuro-Rehabilitation Unit. INTERVENTIONS: Patients received a four-week rehabilitation program composed by daily sessions of conventional physiotherapy and three sessions/week of specific treatment (aquatic vs. on-land). MAIN MEASURES: Primary outcome measures were Berg Balance Scale and Dynamic Gait Index. Secondary outcome measures were Neuropathic Pain Scale, Overall Neuropathy Limitations Scale, Functional Independence Measure, Functional Ambulation Classification, Conley Scale and Medical Research Council Scale score for the strength of hip and ankle flexor and extensor muscles. For each scale, we calculated the difference between the scores at discharge and admission and compared it between the two groups. RESULTS: Forty patients were enrolled: 21 in the water-based rehabilitation group and 19 in the land-based one. Patients were similar between groups. When comparing the groups, we found that "in-water" patients had a significant better improvement in the Dynamic Gait Index score (6.00 (4.00, 7.25) vs. 4.00 (1.25, 6.00), P = 0.0433). On the opposite, the "on-land" group showed a better improvement of the Functional Ambulation Classification score (1.0 (0.75, 1.0) vs. 1.0 (1.0, 2.0), P = 0.0386). CONCLUSION: Aquatic physiotherapy showed an effect comparable to the land-based rehabilitation on gait and balance dysfunctions of neuropathic patients.

BACKGROUND: Gait disturbances in Parkinson's disease (PD) are highly disabling and poorly responsive to drugs, especially in advanced stages. While the efficacy of a treadmill training based on external feedback and cues (treadmill-plus) on gait disturbances in early PD stages is demonstrated, no definitive evidence exists about advanced stages. OBJECTIVE: We aimed to evaluate the feasibility and the effects of a treadmill-plus training on gait disturbances in advanced PD. METHODS: Two hundred and six PD patients from medium to more advanced Hoehn & Yahr stage (stage 2, nâ=â79, stage 3 nâ=â74, and stage 4â=â53) who underwent a 4-week treadmill-plus training, were retrospectively identified. All patients were able to walk on a treadmill for one minute at 1.5âkm/h, without support. Feasibility was evaluated by measuring safety, adverse events, and attrition rate. The effects of treatment were evaluated by assessing, both at enrolment and at the end of treatment, the on-land, self-paced 6-minute Walking Test (6MWT) and the gait parameters obtained from the treadmill during a 1.5âkm/h trial. RESULTS: All patients completed the treadmill-plus training and no adverse events were recorded, even among more disabled patients. After training, we observed a significant improvement in the 6MWT, an increase in step length and a reduction of cadence and step variability in the whole sample. After stratifying patients according to disease stage, we found that patients in more advanced stages experienced the same improvements in all gait parameters as patients in less advanced stages. CONCLUSIONS: Treadmill-plus training is well tolerated and may have a positive impact on many aspects of gait in more advanced PD stages.

BACKGROUND: Quality of life (QoL) is the sense of well-being perceived by people. The improvement of parkinsonian patient's QoL is a crucial goal for clinicians involved in rehabilitative care. In order to provide an appropriate endpoint for the assessment of the effectiveness of rehabilitation treatments on QoL of patients with Parkinson's Disease (PD), in this study we have first translated and then validated the Belastungsfragebogen Parkinson kurzversion (BELA-P-k). This tool allows evaluating separately two crucial aspects: i) the loss of personal autonomy in activities of daily life and ii) the psychological and psychosocial impact of the disease. METHODS: The BELA-P-k was translated from Dutch into Italian. Subsequently 202 PD patients filled out the questionnaire. Patients were also evaluated by using the Parkinson Disease Questionnaire -39 (PDQ39), the Unified Parkinson's Disease Rating Scale (UPDRS), the Mini Mental State Examination (MMSE) and the Frontal Assessment Battery (FAB). RESULTS: The internal consistency for total of two different scores Bothered by (Bb) and Need for Help (NfH) was excellent (p = 0.91) for both categories. The correlation between Bb and NfH categories was significant and strong, very-strong, ranging from 0.78 to 0.88 (all p < 0.0001). Finally, the value of Spearman r for the relationship between Bb and NfH items and PDQ 39 values were significant (p ≤ 0.003). CONCLUSIONS: In conclusion, we validated the BELA-P-k and demonstrated that it is an appropriate and potentially useful tool for assessing QoL in the management of PD. TRIALS REGISTRATION: This trial was retrospectively registered with ClinicalTrials.gov, NCT03073044.
RESUMEN
INTRODUCTION: Our objective is to describe the dietary habits, food preferences and adherence to Mediterranean diet (MeDi) of a large sample of Italian Parkinson's Disease (PD) patients compared to a group of controls. METHODS: Dietary habits of 600 PD patients from throughout Italy and 600 controls matched by gender, age, education, physical activity level and geographical residence, were collected using the ON-GP Food Frequency Questionnaire. Then, we compared patients by disease duration and the presence of swallowing disturbances. RESULTS: Overall, adherence of PD patients (males, 53.8%; mean disease duration, 9.2 ± 7.0 years) to MeDi was similar to controls (score, 4.8 ± 1.7 vs. 4.9 ± 1.6; P = 0.294). Patients consumed less alcohol and fish and drank significantly less water, coffee, and milk which resulted also in lower total fluids intake. On the contrary, they ate more fruit, cooked vegetables, cereals and baked items, more dressings and more sweets in general. Disease duration was associated with increased intake of several food groups but it was not associated with changes in MeDi score (P = 0.721). Patients with swallowing disturbances (n = 72) preferred softer and more viscous food but preferences did not result in differences in dietary pattern. However, patients with dysphagia drank less fluids (P = 0.043). DISCUSSION: PD patients presented different dietary habits and food preferences compared to the general population and adherence to MeDi was not associated with disease duration. Self-reported dysphagia was associated with reduced intake of fluids. These aspects may be amenable to change in order to improve the management of nutritional issues in this patient population.
