The effects of rhythmic auditory stimulation on functional ambulation after stroke: a systematic review

BackgroundSeveral studies have reported the effect of rhythmic auditory stimulation (RAS) on functional ambulation in stroke patients, yet no systematic overview has yet been published. This study aims to synthesize the available evidence describing changes in stroke patients after RAS intervention for functional ambulation and the use of walking assistive devices, and to find out if the effect of RAS and music-based RAS differs depending on the lesioned area.MethodsThe PubMed, PEDro, Cochrane Central Register of Controlled Trials, Web of Science, Scopus and CINAHL electronic databases were searched for reports evaluating the effect of RAS on walking in stroke patients, applying the PICOS criteria for the inclusion of studies.ResultsTwenty one articles were included (948 stroke survivors). Most studies were of good methodological quality according to the PEDro scale, but they had a high risk of bias. The most consistent finding was that RAS improves walking and balance parameters in stroke patients in all phases compared to baseline and versus control groups with conventional treatment. Functional ambulation and the use of walking assistive devices were inconsistently reported. Several studies also suggest that RAS may be as good as other complementary therapies (horse-riding and visual cueing).ConclusionsDespite the beneficial effects of RAS, the question remains as to whether it is better than other complementary therapies. Given the heterogeneity of the interventions, the interventions in control groups, the varied durations, and the different outcome measures, we suggest that care should be taken in interpreting and generalizing findings.PROSPERO RegistrationCRD42021277940.

Effect of Rhythmic Auditory Stimulation against Mirror Therapy on Hand Function in Stroke Patients

Objective: Stroke affects the upper limb function keeping the patient dependent for daily activities. Rhythmic auditory stimulation is proved to be beneficial in upper limb functions, although Mirror therapy and Conventional therapy has their own beneficial effects in stroke. The study aimed at comparing the effect of rhythmic auditory stimulation against mirror therapy and conventional therapy. Method: Sixty participants were taken for the study divided into three groups, 20 in each. Interventions were planned with Group A for Conventional therapy, Group B for Rhythmic Auditory Stimulation and Group C as Mirror therapy. Hand grip was measured by Hand held Dynamometer and Hand function by using Action Research Arm Test. Treatment was given for 20 minutes in a day, for 5 sessions a week extending for 4 weeks. Findings: The results obtained after the analysis showed a significant difference in ARAT scores among three groups: Control (34.808.27), RAS (40.607.12) and Mirror therapy (33.507.86) with mean post-test scores (F=4.7400, p=0.0120) and change from pre-test to post-test (F=67.2790, p=0.0001). A significant difference was observed among three groups: Control (21.286.82), RAS (27.616.94) and Mirror therapy (23.39 5.47) with mean post-test scores (F=5.0040, P=0.0100) and pretest posttest score for hand grip (F=59.6750, P=0.0001). Novelty: Mirror therapy and rhythmic auditory stimulation influences the visual and the auditory system respectively. The novelty of this study is being exhibited in identifying the effective intervention that can influence the neuroplasticity of the brain in the learning process. Conclusion: Both RAS and mirror therapy programme have been found to improve hand functions and grip in paretic arms; hence they can be used as an add-on intervention alongside convention therapy to help hemi paretic patients regain upper extremity function.

Effects of rhythmic auditory stimulation on vision: Oscillations in performance can be enhanced, but not induced.

A variety of reports suggest that rhythmic auditory stimulation can entrain visual perception, inducing perceptual oscillations as a function of time relative to the auditory rhythm. These effects have, to date, been reported only for stimulation frequencies at and below 3 Hz. Here we investigate the effects of rhythmic auditory stimulation on the detection of masked visual targets when this stimulation occurs at frequencies to which the visual system has been shown to entrain (8-12 Hz). Across four experiments, we found no consistent evidence of poststimulation modulations in performance induced by 8.5, 10.6, or 12.1 Hz auditory stimulation. This absence of a consistent auditory-to-visual effect was paralleled by an absence of unimodal effects (oscillations in auditory performance) following 12.1 Hz auditory stimulation. In a fifth experiment, we found that although auditory stimulation alone did not induce oscillations in visual performance, auditory stimulation did enhance the effects of concurrent visual stimulation. Notably, this enhancement did not require synchronous presentation of stimuli. These observations are consistent with recent reports that passive auditory stimulation beyond 5 Hz induces neither auditory perceptual oscillations nor visual cortical oscillations and suggest limits to the extent of cross-modal entrainment.

Influência da estratégia de Estimulação Auditiva Rítmica com música associada à fisioterapia sobre os sintomas depressivos no Parkinson

ABSTRACT Depressive symptoms are commonly found in Parkinson’s disease and are considered an important factor for an individual’s poor quality of life and disability. Therapeutic interventions based on rhythm and music, such as rhythmic auditory stimulation, have been used to treat the mobility and seem to positively influence on mood. This study aims to evaluate the effect of rhythmic auditory stimulation using music associated with physical therapy on mood in individuals with Parkinson’s, with an emphasis on depressive symptoms. This is a quasi-experimental study with a final sample of 18 patients aged 40-80 years, with a clinical diagnosis of idiopathic Parkinson’s disease, in the mild to moderate stages of the disease. Patients were randomized into two groups: Rhythmic Auditory Stimulation and Control Groups. Depressive symptoms were assessed using the Portuguese version of the Beck Depression Inventory. Both groups reduced their The Beck Depression Inventory scores. However, only in the Rhythmic Auditory Stimulation Group the reduction was significant, with a mean difference in the inventory score three times greater than the Control Group.

Effects of rhythmic auditory stimulation on upper-limb movements in patients with Parkinson's disease

IntroductionRhythmic auditory stimulation (RAS) is an effective technique extensively used to alleviate lower-limb bradykinesia in patients with Parkinson's disease (PD). However, RAS effects on upper-limb bradykinesia have not been well studied. This study investigated immediate effects of RAS on upper-limb movements in PD patients and healthy people. MethodsPD patients (n = 23) and age- and gender-matched healthy controls (n = 23) executed left-hand, right-hand, and both-hand movement tasks of the Purdue Pegboard Test when listening to the beats of RAS, including 100%, 110%, and 120% of the baseline tempo, which was fastest movement performance of each participant without the aid of RAS. Sequence of RAS and tasks was randomized for each participant. ResultsPD patients had slower upper-limb movements than did health controls. An interaction was found between RAS and tasks. In both patients and controls and for all task conditions, 120%RAS induced higher scores than did 110% RAS, and the latter induced higher scores than did 100%RAS. In both patients and controls and for all RAS conditions, the right-hand condition induced higher scores than did the left-hand condition, and the latter induced higher scores than did the both-hand condition. ConclusionsRAS was effective in regulating upper-limb movements in PD patients, which may be explained by rich neural connections between auditory and motor cortical areas in humans. Clinical practitioners should consider using RAS in clinical therapy. Future neuroimaging studies are needed to explore neural mechanisms of RAS in PD patients.

Short Term Effects of Rhythmic Auditory Stimulation with Body Weight Supported Treadmill Training on Gait and Balance in Individuals with Incomplete Spinal Cord Injury

Background: Rhythmic auditory stimulation and body weight supported treadmill training both are standardized gait rehabilitation techniques. However there is limited literature evaluating the effect of rhythmic auditory stimulation and its combination with gait training in spinal cord injury. Aim of this study is to determine the short term effectiveness of rhythmic auditory stimulation with body weight supported treadmill training on gait and balance in individuals with incomplete Spinal Cord Injury. Method: A randomized control study design. 8 subjects with incomplete spinal cord injury who met the inclusion criteria were randomly allocated into two groups: Experimental and Control. Subjects in experimental group were given body weight supported treadmill training with rhythmic auditory stimulation. Subjects in Control Group were given Body weight supported treadmill training alone. Both the groups received conventional rehabilitation as well. Both groups received training for 30 minutes, five times a week for two weeks (10 sessions). Outcome Measures: Gait parameters i.e. cadence, velocity, step length were measured using the Biodex Gait Trainer 2TM, level of walking performance measured using Walking Index for Spinal Cord Injury II, and balance was evaluated using Prokin 252NTM , Berg Balance Scale, and Activity specific Balance Confidence scale. Results: No significant improvement was found on gait parameters i.e. cadence, velocity, step length which were measured using the Gait Trainer, level of walking performance measured using WISCI II, and balance which was evaluated using Prokin 252NTM , Berg Balance Scale, and Activity specific Balance Confidence scale. Conclusion: Rhythmic auditory stimulation didn’t have any positive effect on gait training in incomplete spinal cord injured patients. Further studies are warranted to explore the entrainment effects of rhythmic auditory stimulation in spinal cord injured individuals on gait rehabilitation.

Effectiveness of Rhythmic Auditory Stimulation on Gait in Parkinson Disease: A Systematic Review and Meta-analysis.

Parkinson disease is a neurodegenerative disease present in approximately 2% of the population older than 65 years. Rhythmic auditory stimulation in the early 1990s aimed to improve individual mobility in terms of gait speed, stride length, and cadence. Our systematic review and meta-analysis aimed to summarize and evaluate the evidence of the effects of rhythmic auditory stimulation on gait speed, stride length, and cadence in patients with Parkinson disease. A systematic review and meta-analysis of randomized controlled trials was conducted to determine the efficacy of rhythmic auditory stimulation in patients with Parkinson disease. Five studies were included in the review (209 patients). Rhythmic auditory stimulation resulted, on average, a gait speed improvement of 0.53 standard deviation (SD) units (95% CI, 0.23 to 0.83; P = .0005), a stride length improvement of 0.51 SD units (95% CI, 0.18 to 0.84; P = .003) greater than that in the control group. All trials contained a risk of bias due to a lack of blinding. The quality of evidence was low. No adverse events were identified. Rhythmic auditory stimulation may have a beneficial effect on gait speed and stride length in patients with Parkinson disease. Future studies should consider a power analysis to recruit an adequate number of subjects and minimize the risk of sample bias. Further research should provide the additional results required for an acceptable estimate of the effects of rhythmic auditory stimulation on gait in patients with Parkinson disease.

Effects of rhythmic auditory stimulation on walking during the 6-minute walk test in patients with generalised Myasthenia Gravis

Introduction Rhythmic auditory stimulation (RAS) has been shown to improve gait parameters in several neurological diseases, both in walk-training interventions and in one-time walking tests, but the effect in myasthenia gravis (MG) is unknown. Objective The aim of this study was to examine if RAS improves walking distance and gait speed in patients with generalised myasthenia gravis (gMG) in the 6-minute walk test (6MWT). Methods Forty-eight patients with gMG walked two 6MWTs under different conditions: (1) walking with RAS with a frequency of 100% of the patient’s fastest gait speed, (2) walking with RAS with a frequency of 110% of the patient’s fastest gait speed, or (3) walking in silence. Results RAS with a frequency of 110% of the patient’s fastest gait speed increased the walking distance by 8.3 metres in the 6MWT vs standard 6MWT (p = 0.01), without increasing average walking heart rate (HR) or Borg scores. Conclusions This study indicates that RAS may improve gait speed and walking distance in patients with gMG without additional exertion as judged by HR and Borg scores. Based on these results, RAS could be used as part of a physical rehabilitation program for patients with gMG.

Effects of rhythmic auditory stimulation on functionality in Parkinson’s disease

Abstract Introduction: Functionality is affected by the clinical characteristics and progression of Parkinson’s disease (PD). Objective: Assess the effects of a therapeutic exercise program associated with music-based rhythmic auditory stimulation (RAS) on the Activities and Participation Profile (APP) related to mobility of people with PD. Methods: Intervention study investigating people with moderate PD recruited from the Hospital das Clínicas of the Federal University of Pernambuco and the Parkinson’s Disease Association of Pernambuco. The APP related to mobility of the participants was assessed based on the International Classification of Functioning Disability and Health (ICF). The APP contains 23 activity/participation items scored from 0 (no problem) to 4 (complete problem). The intervention consisted of 10 outpatient sessions of a therapeutic exercise program associated with music-based RAS, applied using a smartphone application (ParkinSONS®), performed twice a week, with an average duration of 50 minutes per session. Given the metric nature of the variable and its non-normal distribution, Wilcoxon’s test was applied, considering p < 0.05. Results: In the sample of 8 patients, there was a significant decline in APP scores after intervention (p = 0.018*), indicating a positive change. Scores for all the APP activities decreased following the intervention, except for “transferring oneself to the left side while lying down”. Conclusion: In this study, a therapeutic exercise program associated with music-based RAS had a positive effect on the APP related to mobility of people with moderate PD.

Effects of cadence-compatible melodic rhythmic auditory stimulation implementation on gait in patients with Parkinson’s disease

Purpose Progressive loss of dopaminergic neurons in basal ganglia is blamed as the main source of gait disturbance in Parkinson's disease (PD). It is known that the normal step pattern does not disappear in PD, but there is a problem in activating the correct step response. The aim of this study was to investigate the effect of Rhythmic Auditory Stimulation (RAS), which is an external stimulus, on gait in individuals with PD. Materials and methods Twenty-six individuals, 13 in the PD group and 13 in the control group, participated in the study. All individuals were asked to walk under four different RAS conditions configured with beat frequency and melodic variations. Time–distance parameters and gait performance of the individuals were evaluated. Results RAS significantly increased the gait speed of the individuals with PD compared to the control group. RAS set to 10% increase in the cadence of the patient with melody (10 M+) was found to be more effective than the RAS set to normal cadence of the patient without melody (0 M-) (p < 0.05). While all RAS implementations increased the stride length of the individuals with PD (p < 0.05), there was no change in the control group. RAS did not affect the return time in both groups. Conclusions Our study has shown that RAS implementation improves gait in individuals with PD both in terms of time–distance parameters and performance, especially when set to 10% more than the patient's gait cadence. It was concluded that cadence-compatible melodic RAS can be safely included in PD rehabilitation programs.

Effects of rhythmic auditory stimulation on upper-limb movement speed in patients with schizophrenia spectrum disorders.

Movement slowness, linked to dysfunctional basal ganglia and cerebellum, is prevalent but lacks effective therapy in patients with schizophrenia spectrum disorders. This study was to examine immediate effects of rhythmic auditory stimulation (RAS) on upper-limb movement speed in patients. Thirty patients and 30 psychiatrically healthy people executed the right-hand task and the both-hand task of the Purdue Pegboard Test when listening to RAS with two tempi: normal (equal to the fastest movement tempo for each participant without RAS) and fast (120% of the normal tempo). The testing order of the RAS tempi for each participant was randomized. Patients had lower scores of right-hand and both-hand tasks than did psychiatrically healthy people. Scores of right-hand and both-hand tasks were higher in the fast-RAS condition than the normal-RAS condition in participants. This is the first study to explore the possibility of applying RAS to movement therapy for patients with schizophrenia spectrum disorders. The results demonstrated that faster RAS was effective in inducing faster upper-limb movements in patients and psychiatrically healthy people, suggesting that manipulating RAS may be a feasible therapeutic strategy utilized to regulate movement speed. The RAS may involve alternative neural pathways to modulate movement speed and thus to compensate for impaired function of basal ganglia and cerebellum in patients.

Gait Training Methods and ChangesiIn Gait Parameters in Parkinson`s Disease (Literature Review)

Parkinson’s disease is a chronic progressive neurological disorder that can impact function to a variable degree. Changes in gait parameters are the most common signs of Parkinson’s disease. Patients with Parkinson’s disease walk with a reduced step length, step time, walking velocity and walking cadence, increased stride cycle time, coefficient of variation of the step amplitude and step time and increased risk to fall. So, various gait training methods are applied. The effect of rhythmic auditory stimulation on gait in Parkinson’s disease patients is analysed. We can use various kinds of music, metronome, scansion and clapping as a rhythmic auditory stimulation.One of gait training methods in Parkinson’s disease patients is treadmill training. There are attempts to combine treadmill training with transcranial magnetic stimulation and virtual reality. We can use Nordic walking method and because walking technique requires straight posture, trunk rotation, bigger step and heel stride. More often robot–assisted gait training is used in patients with Parkinson’s disease gait training. The effect of dual–tasking and walking with music methods for gait and balance training in patients with Parkinson’s disease is also analysed. This method requires participants to perform primary and secondary tasks at the same time. The secondary task can be cognitive or motor. Dual–tasking is widely analysed because opinions about applying this method are very controversial. Walking with music method is more often analysed in scientific literature. This method could not be compared to rhythmic auditory stimulation method because the latter requires precise walking to rhythm and walking with music method is oriented to emotional component (music is chosen according patients’ music taste). As these methods are applied, we can see an increase in chosen walking and maximal walking velocities, step length and time, distance covered, and decrease in the coefficient of variation of the step time and turning time.Keywords: Gait impairments, walking velocity, rhythmic auditory stimulation.

Immediate effects of rhythmic auditory stimulation on gait kinematics in Parkinson’s disease ON/OFF medication

ObjectiveGait impairment is a highly disabling symptom for Parkinson’s disease (PD) patients. Rhythmic auditory stimulation (RAS), has shown to improve spatio-temporal gait parameters in PD, but only a few studies have focused on their effects on gait kinematics, and the ideal stimulation frequency has still not been identified. MethodsWe enrolled 30 PD patients and 18 controls. Patients were evaluated under two conditions (with (ON), and without (OFF) medications) with three different RAS frequencies (90%, 100%, and 110% of the patient’s preferred walking cadence). Spatial-temporal parameters, joint angles and gait phases distribution were evaluated. A novel global index (GPQI) was used to quantify the difference in gait phase distribution. ResultsAlong with benefits in spatial-temporal parameters, GPQI improved significantly with RAS at a frequency of 110% for both ON and OFF medication conditions. In the most severe patients, the same result was observed also with RAS at 100%. ConclusionsRAS administration, at a frequency of 110% of the preferred walking frequency, can be beneficial in improving the gait pattern in PD patients. SignificanceWhen rhythmic auditory stimulation is provided to patients with PD, the selection of an adequate frequency of stimulation can optimize their effects on gait pattern.

Cognitive effects of rhythmic auditory stimulation in Parkinson’s disease: A P300 study

Rhythmic auditory stimulation (RAS) may compensate dysfunctions of the basal ganglia (BG), involved with intrinsic evaluation of temporal intervals and action initiation or continuation. In the cognitive domain, RAS containing periodically presented tones facilitates young healthy participants’ attention allocation to anticipated time points, indicated by better performance and larger P300 amplitudes to periodic compared to random stimuli. Additionally, active auditory-motor synchronization (AMS) leads to a more precise temporal encoding of stimuli via embodied timing encoding than stimulus presentation adapted to the participants’ actual movements.Here we investigated the effect of RAS and AMS in Parkinson’s disease (PD). 23 PD patients and 23 healthy age-matched controls underwent an auditory oddball task. We manipulated the timing (periodic/random/adaptive) and setting (pedaling/sitting still) of stimulation. While patients elicited a general timing effect, i.e., larger P300 amplitudes for periodic versus random tones for both, sitting and pedaling conditions, controls showed a timing effect only for the sitting but not for the pedaling condition. However, a correlation between P300 amplitudes and motor variability in the periodic pedaling condition was obtained in control participants only. We conclude that RAS facilitates attentional processing of temporally predictable external events in PD patients as well as healthy controls, but embodied timing encoding via body movement does not affect stimulus processing due to BG impairment in patients. Moreover, even with intact embodied timing encoding, such as healthy elderly, the effect of AMS depends on the degree of movement synchronization performance, which is very low in the current study.

Effect of Rhythmic Auditory Stimulation On Gait In Patients With Stroke (P4.039)

Changes in gait patterns induced by rhythmic auditory stimulation for adolescents with acquired brain injury.

The effects of rhythmic auditory stimulation (RAS) on gait in adolescents with acquired brain injury (ABI) were investigated. A total of 14 adolescents with ABI were initially recruited, and 12 were included in the final analysis (n = 6 each). They were randomly assigned to the experimental (RAS) or the control (conventional gait training) groups. The experimental group received gait training with RAS three times a week for 4 weeks. For both groups, spatiotemporal parameters and kinematic data, such as dynamic motions of joints on three-dimensional planes during a gait cycle and the range of motion in each joint, were collected. Significant group differences in pre-post changes were observed in cadence, walking velocity, and step time, indicating that there were greater improvements in those parameters in the RAS group compared with the control group. Significant increases in hip and knee motions in the sagittal plane were also observed in the RAS group. The changes in kinematic data significantly differed between groups, particularly from terminal stance to mid-swing phase. An increase of both spatiotemporal parameters and corresponding kinematic changes of hip and knee joints after RAS protocol indicates that the use of rhythmic cueing may change gait patterns in adolescents with ABI.
