Virtual functional mobility test: A potential novel tool for assessing mobility of individuals with Parkinson's disease in a multitask condition

There are few instruments available for evaluating functional mobility during multitasking in people with Parkinson's Disease (PD). Virtual Reality is a potentially tool capable of aiding in the evaluation of functional mobility. The purpose of this study is to verify the potential of the Virtual Functional Mobility Test (VFMT) as a clinical tool to assess functional mobility of people with PD during multitasking condition. 25 people with PD and 25 people without PD, matched for age and sex, were recruited. Participants were evaluated through the Trail Making Test, Timed "UP and GO" test, Timed "UP and GO" test in dual task condition and through the VFMT, composed of 1) a simple task, and 2) a complex task. The VFMT and clinical tests were sensitive to differentiate the groups, except the trail making test part B (p = 0.332) and complex task (p = 0.052). Strong correlations were observed between parts A and B of the trail making test (r = 0.75) and complex task (r = 0.72); Moderate correlations between Timed Up and Go test and Timed Up and Go test in dual task condition with simple task (r = 0.47) and complex task (r = 0.55), respectively, were found. The complex task and simple task showed excellent and moderate reliability intra-rater, respectively. It was concluded that the novel VFMT is feasible, sensible, reliable and has potential as an instrument for the evaluation of functional mobility during multitasking in people with PD.

Efficacy of dance for Parkinson's disease: a pooled analysis of 372 patients

BACKGROUND

Parkinson's disease (PD) is a neurodegenerative disorder that presents with motor and nonmotor symptoms such as bradykinesia, resting tremor, postural instability, and cognitive and neuropsychiatric manifestations. Dance therapy or complex motor activity, besides pharmacological treatment, may have benefits in PD patients.

OBJECTIVE

To assess the effect of dance in patients with PD.

METHODS

We searched for clinical trials in PubMed, Scopus, and Web of Science, and Cochrane till April 2020 using relevant keywords. Data were extracted and pooled as mean difference (MD) with 95% confidence interval (CI) by Review Manager 5.3.

RESULTS

Fourteen randomized controlled trials with 372 patients were included. Dance showed a significant improvement over the control group in term of the Unified Parkinson's Disease Rating Scale III (UPDRS III) after three (MD = - 4.49, 95% CI [- 6.78, - 2.21], p = 0.00001), six, (MD = - 5.96, 95% CI [- 8.89, - 3.02], p < 0.0001), and 12 months (MD = - 14.58, 95% CI [- 24.76, - 4.4], p = 0.005), and Mini-BES test after 12 months. Compared to exercise, dance showed a significant improvement in Timed Up and Go (TUG) test, Berg Balance Scale (BBS), and Mini-BES test.

CONCLUSION

In comparison to other types of exercise or no activity, dance improves the symptoms and outcomes in patients with PD, especially motor symptoms. Dance also has positive effects on balance, functional mobility, and cognition.

Nordic Walking and Free Walking Improve the Quality of Life, Cognitive Function, and Depressive Symptoms in Individuals with Parkinson's Disease: A Randomized Clinical Trial

Nordic walking's (NW) degree of effectiveness regarding health-related parameters in people with Parkinson's Disease (PD) is a subject of debate. While NW seems to improve functionality, a clear non-motor benefit has not been demonstrated. The aim of this randomized controlled trial was to compare the effects of 9-week NW and free walking (FW) training programs on quality of life, cognitive function, and depressive symptoms in individuals with PD. Thirty-three people with PD, (Hoehn and Yahr 1-4) were randomized into two groups: NW (n = 16) and FW (n = 17). We analyzed quality of life, cognitive function, depressive symptoms, and motor symptoms. Significant improvements were found in the overall, physical, psychological, social participation, and intimacy domains of quality of life, as well as in cognitive function and depressive symptoms for both groups. Only the NW group showed improvement in the autonomy domain. Individuals with PD had a similar enhancement of non-motor symptoms after walking training, with or without poles. However, the NW group showed a more significant improvement in the autonomy domain, strengthening the applied and clinical potential of NW in people with PD. Future studies are needed to determine the efficacy of walking training without poles in subjects with PD.

Can Samba and Forró Brazilian rhythmic dance be more effective than walking in improving functional mobility and spatiotemporal gait parameters in patients with Parkinson's disease?

Background

Parkinson’s disease (PD) causes motor and nonmotor disorders in patients. Unlike aerobic training, potential adaptations from the practice of dance are less understood in PD, particularly compared with better known exercise modes. This study aimed to verify and compare the effects of a Brazilian dance program, inspired by Samba and Forrró rhythms, and a walking program on functional mobility and spatiotemporal gait parameters in patients with PD.

Methods

Eighteen participants with PD were divided into a dance group (DG) and a walking group (WG) and were assessed before and after an intervention period of 24 1-h sessions, performed twice per week for 12 weeks. The timed-up-and-go test (TUG) and walking kinematics at self-selected speed (SSS) and fast speed (FS) were determined. The generalized estimating equation method was used to compare the DG and WG pre- and post-intervention and to evaluate the group*time interaction (α <  0.05).

Results

Both groups demonstrated a significant improvement in TUG test at SSS (p = 0.02; effect size [ES] = 0.42) and FS (p = 0.02; ES = 0.24). In general, spatiotemporal parameters remained unchanged, except at SSS, in which the DG increased the stride frequency (p = 0.011; ES = 0.72). At FS, the swing time demonstrated a significant group*time interaction (p <  0.001; ES = 1.10), in which the two groups exhibited different behaviors: DG decreased (p = 0.015) and WG increased (p = 0.012).

Conclusions

Functional mobility improved similarly in both groups. The results suggest that a 12-week program of Brazilian dance was sufficient to produce improvements in functional mobility and gait in individuals with PD.

Trial registration

This study is registered with the International Clinical Trial Registry under number NCT03370315. Registered December 28, 2017 - Retrospectively registered.

Effects of dance practice on functional mobility, motor symptoms and quality of life in people with Parkinson's disease: a systematic review with meta-analysis

BACKGROUND

Patients with Parkinson's Disease (PD) undergo motor injuries, which decrease their quality of life (QL). Dance, added to drug therapy, can help treating these patients AIMS: To conduct a systematic review with meta-analysis with the aim to analyze the effects of dance classes in comparison to other interventions or to the absence of intervention, in randomized clinical trials (RCTs), on functional mobility, motor symptoms and QL of PD patients METHODS: The search was conducted in MEDLINE, LILACS, SciELO, Cochrane and PsycINFO (last searched in August 2017). RCTs analyzing dance effects in comparison to other physical training types or to no intervention, on functional mobility, motor symptoms and QL of PD patients were selected. The outcomes assessed were motor symptoms with Unified PD Rating Scale III (UPDRSIII), functional mobility with Timed Up and Go Test (TUG), endurance with 6 min walking test (6MWT), freezing of gait with Freezing of Gait Questionnaire (FOG_Q), walking velocity with GAITRite and QL with PD Questionnaire (PDQ39). Two reviewers independently extracted methodological quality and studies data. Results are presented as weighted mean differences.

RESULTS

Five RCTs were included, totaling 159 patients. Dance promoted significant improvements on UPDRSIII, and a decrease in TUG time when compared to other types of exercise. In comparison to the absence of intervention, dance practice also showed significant improvements in motor scores.

CONCLUSION

Dance can improve motor parameters of the disease and patients' functional mobility.

Comparison of three physical therapy interventions with an emphasis on the gait of individuals with Parkinson’s disease

Abstract Introduction: Gait impairments are one of the earliest signs reported by patients with Parkinson’s disease (PD) and cause an increased number of falls and decreased quality of life among these patients. Objective: To compare the effectiveness of three physical therapy interventions using Rhythmic Cues (RC), Swiss Ball (SB) and Dual Task (DT), with an emphasis on gait treatment (step and stride length, duration and velocity), in individuals with PD. Methods: Quasi-randomized clinical trial addressing a sample composed of 45 individuals assigned to three groups. The individuals were assessed before and after the intervention protocol using the following: Modified Hoehn and Yahr Scale (HY), Unified Parkinson’s Disease Rating Scale (UPDRS), Footprint analysis, Video Gait analysis, and Timed Up and Go Test (TUG). The groups were homogeneous concerning age, HY and UPDRS. Statistical analysis was performed using SPSS, version 20.0. Results: Statistically significant differences were found in all the variables analyzed in the RC and SB groups when compared in the pre- and post-intervention. With the exception of the TUG variable, the DT group presented statistically significant differences in all the remaining variables. Conclusion: The three interventions were effective for the outcomes under study, but the SB group presented the greatest magnitude of change (effect size), while the RC group presented the greatest improvement in the temporal gait variables (duration and velocity) and TUG.

Do cognitive tasks during gait increase the risk of accidents with pedestrians? A study based on electromyographic parameters

Abstract Introduction Accidents involving pedestrians are responsible for many cases of serious injuries and deaths. Crossing streets safely requires complex planning and cognitive demand because it is necessary to perform more than one task at a time. Objective The aim of this study was to identify electromyographic changes during gait in young subjects who performed the cognitive tasks concurrently. Methods The study included 17 younger women aged between 18 and 25 years. Data collection was performed on a treadmill. The volunteers were instructed to walk in four different conditions: normal gait (NG), gait with dual easy task (DET), gait with dual hard task (DHT) and gait with dual mixed task (DMT). Results Significant differences were found between the MN condition to the other conditions for all muscles and, during the NG, smaller values of muscle activation were found. Muscle co-contraction between muscles VM / BF showed a significant difference between the conditions of NG and DMT (p = 0.04) and, during the NG, smaller values of co-contraction were observed. Conclusion The data of this study permits to conclude that the competition between motor and cognitive resources significantly affects the levels of muscle activation and co-contraction during gait in young adult women. Thus, we conclude that the performance of dual cognitive tasks while driving can be considered a risk factor for safe driving.
