Exercice physique ; Maladie de Parkinson ; Rééducation et réadaptation ; TremblementMots-clés : Exercise Movement disorders Troubles de la motricité Tremor Parkinson Disease Résumé : "Objectives
To develop a rapid cadence cycling intervention (active-assisted cycling [AAC]) using a motorized bike and to examine physiological perimeters during these sessions in individuals with Parkinson's disease (PD). A secondary goal was to examine whether a single session of AAC at a high cadence would promote improvements in tremor and bradykinesia similar to the on medication state.
Design
Before-after pilot trial with cross-over.
Setting
University research laboratory.
Participants
Individuals with idiopathic PD (N=10, age 4574y) in Hoehn and Yahr stages 1 to 3.
Intervention
Forty minutes of AAC.
Main Outcome Measures
Heart rate, pedaling power, and rating of perceived exertion were recorded before, during, and after a bout of AAC. Functional assessments included tremor score during resting, postural, and kinetic tremor.
Results
This AAC paradigm was well tolerated by individuals with PD without excessive fatigue, and most participants showed improvements in tremor and bradykinesia immediately after a single bout of cycling.
Conclusions
This paradigm could be used to examine changes in motor function in individuals with PD after bouts of high-intensity exercise."Disponible en ligne : Oui En ligne : http://www.archives-pmr.org/article/S0003-9993(12)00360-7/abstract Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=117338

Exercice physique ; Maladie de Parkinson ; Posture ; Rééducation et réadaptationMots-clés : Cues Signaux Exercise Movement disorders Troubles de la motricité Neurological rehabilitation Rééducation neurologique Parkinson disease Résumé : Objective
To characterize anticipatory postural adjustments (APAs) across a variety of step initiation tasks in people with Parkinson disease (PD) and healthy subjects.
Design
Cross-sectional study. Step initiation was analyzed during self-initiated gait, perceptual cued gait, and compensatory forward stepping after platform perturbation. People with PD were assessed on and off levodopa.
Setting
University research laboratory.
Participants
People (N=31) with PD (n=19) and healthy aged-matched subjects (n=12).
Interventions
Not applicable.
Main Outcome Measures
Mediolateral (ML) size of APAs (calculated from center of pressure recordings), step kinematics, and body alignment.
Results
With respect to self-initiated gait, the ML size of APAs was significantly larger during the cued condition and significantly smaller during the compensatory condition (P<.001 healthy subjects and patients with pd did not differ in body alignment during the stance phase prior to stepping. no significant group effect was found for ml size of apas between pd. however reduction apa from cued compensatory stepping significantly less pronounced off medication compared as indicated by a condition interaction differences were comparing on medications.> Conclusions
Specific stepping conditions had a significant effect on the preparation and execution of step initiation. Therefore, APA size should be interpreted with respect to the specific stepping condition. Across-task changes in people with PD were less pronounced compared with healthy subjects. Antiparkinsonian medication did not significantly improve step initiation in this mildly affected PD cohort.Disponible en ligne : Oui En ligne : https://login.ezproxy.vinci.be/login?url=https://www.sciencedirect.com/science/a [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=118152

Exercice physique ; Hydrothérapie ; Maladie de Parkinson ; Rééducation et réadaptationMots-clés : Exercise Gait Démarche Hydrotherapy Parkinson disease Résumé : Objective
To evaluate the effects of aquatic exercise therapy on gait variability and disability compared with usual care for people with Parkinson disease (PD).
Design
Single-blind randomized controlled trial.
Setting
Community-based hydrotherapy pool.
Participants
Individuals with PD (Hoehn-Yahr stages IIII) (N=21).
Interventions
Participants were randomly assigned to either an aquatic exercise therapy group (45min, twice a week for 6wk) or a group that received usual care.
Main Outcome Measures
The primary outcome measure was gait variability as measured using a motion capture system. Secondary outcomes were quality of life measured on the Parkinson's Disease Questionnaire-39 and freezing of gait and motor disability quantified by the Unified Parkinson's Disease Rating Scale. Feasibility was evaluated by measuring safety, adverse events, and participant satisfaction.
Results
People in the aquatic therapy group and usual care group showed similar small improvements in gait variability. The aquatic therapy group showed greater improvements in disability than the usual care group (P<.01 no differences between groups or over time were identified for freezing of gait quality life. aquatic therapy sessions safe and enjoyable with adverse events.> Conclusions

Titre : Automated Mechanical Peripheral Stimulation Effects on Gait Variability in Individuals With Parkinson Disease and Freezing of Gait: A Double-Blind, Randomized Controlled Trial Type de document : Article Auteurs : Ana Francisca Rozin Kleiner ; Aline Souza Pagnussat ; Camila Pinto Article en page(s) : p. 2420-2429 Langues : Anglais (eng) Descripteurs : HE Vinci
Congélation ; Maladie de Parkinson ; Rééducation et réadaptationMots-clés : Freezing Gait Démarche Parkinson Disease Résumé : Objective
To assess the effects of automated peripheral stimulation (AMPS) in reducing gait variability of subjects with Parkinson disease (PD) and freezing of gait (FOG) treated with AMPS and to explore the effects of this treatment on gait during a single task (walking) and a dual task (walking while attending the word-color Stroop test).
Design
Interventional, double-blinded, placebo-controlled, randomized trial.
Setting
Clinical rehabilitation.
Participants
Thirty subjects were randomized into 2 groups: AMPS (n=15) and AMPS sham (n=15).
Interventions
Both groups received 2 treatment sessions a week for 4 consecutive weeks (totaling 8 treatment sessions). AMPS was applied by using a medical device (Gondola) and consisted in mechanical pressure stimulations delivered by metallic actuators on 4 areas of the feet. Treatment parameters and device configuration were modified for AMPS sham group.
Main Outcome Measures
Gait analyses were measured at baseline and after the first, fourth, and eighth treatment sessions.
Results
Interactions among groups and sessions were found for both conditions while off anti-Parkinsonian medications. AMPS decreased gait variability in subjects with PD and FOG for both single and dual task conditions.
Conclusions
AMPS is an effective add-on therapy for treating gait variability in patients with PD and FOG.Disponible en ligne : Oui En ligne : https://login.ezproxy.vinci.be/login?url=https://www.sciencedirect.com/science/a [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=119100
