Balance Training in Parkinson's Disease Using Cues

Study Overview
=================
Brief Summary
-----------------
Verifying the efficiency of motor training associated with visual and auditory cues on the balance, and postural anticipatory and compensatory adjustments of patients with Parkinson's Disease (PD), for prevent fall rate in people with PD. It is a single blinded, randomized clinical trial performed at Center of Research of the courses of Speech Therapy, Physical Therapy and Occupational Therapy of São Paulo University.

Detailed Description
-----------------
The objective of this work is verifying the efficiency of motor training associated with visual and auditory cues on the balance, and postural anticipatory and compensatory adjustments of patients with Parkinson's Disease (PD), for prevent fall rate in people with PD. It is a double blinded, randomized clinical trial performed at Center of Research of the courses of Speech Therapy, Physical Therapy and Occupational Therapy of São Paulo University. Forty two patients with idiopathic PD will take part in this study, at stages 2 to 3 of the Hoehn and Yahr Classification (HY). They are randomly assigned into one of 3 groups: one group receiving motor training associated to external cues (ET), the other one group performing motor training only (MT) and a third group receiving no treatment just generalize orientations. Performance in gait and balance are assessement before and after 10 training sessions (two 45-minute sessions per week) for the ET and MT groups, and before and after 5 weeks for the CG, using the BERG test (BT), Postural Stress Test (PST), Time Up and Go (TUG). Patients are also assessment for independence in daily life activities and motor performance using section II and III of the Unified Parkinson's Disease Rating Scale (UPDRS); for Quality of Life using the Parkinson's Disease Quality of Life (PDQL), and for emotional state by Beck's Depression Inventory (BDI). The training consist on: the experimental group receiving the motor program to balance associated to rhythmical auditory cues. The directions of the training were I. self-perception (strategies - Verbal and visual guidance); II. motor performance (Speed variation, Range of motion, Trunk mobility, Turning, balance exercices); III. Attention Strategies (Division of attention between guidance, environment and yourself movement, Maintenance of attention during all sets); IV. Cues. The training program consisted on 5 weeks with 45 minutes duration, divided in 05 minutes warm-up, 30 minutes main part, 10 minutes cool down. The control group (CG) wasn't training just received orientations. Each session will consist on 05 minutes Warm-Up including: Muscle stretching, joint movements, upper and lower global, movement slowly and using wide joint movement range, and turning. The Main Part including: Head movement (bending, rotation, and leaning sideways), Axial and proximal movements, coordinated movements with Upper and Lower range and speed, Functional reach, weight shifts, stationary and walking gait with rhythmic and speed variation, postural reactions, trunk rotation, Balance exercises. And the last part is the Cool Down, including: Slow walk, breathing exercises associated to Upper limb movements and global muscular relaxation and stretching. During the study there aren't changes on patient's usual medicine. The subjects will be reassessment after 4 and 30 weeks without the program training.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| UPDRS | The Unified Parkinson's Disease Rating Scale (UPDRS) is a rating scale used to follow the longitudinal course of Parkinson's disease | up to 30 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Berg Balance Scale (BBS) Berg Balance Scale | Berg Balance Scale assesses the functional balance of patients with Parkinson´s disease. It is a clinic assessment of patient that evaluate the antecipatory postural adjustments and the performance of patient to stand up and sit down, turn on and step, among others situations. | up to 30 weeks | 
| Dynamic Gait Index | The scale assesses the ability to adapt the gait during motor tasks with different demands | up to 30 weeks | 
| Retropulsion test | The Retropulsion test, by which an unexpected, quick and firm jerk on the shoulder is given in a backward direction.It is a clinic assessment of patient that evaluate the compensatory postural adjustments | up to 30 weeks | 
| Timed Up and Go test (TUG) | The Timed Up and Go test is a short, practical test by which gait and balance are tested | up to 30 weeks | 
| Balance Evaluation Systems Test (BESTest) | Clinical balance assessment tool that aims to target 6 different balance control systems so that specific rehabilitation approaches can be designed for different balance deficits. | up to 30 weeks |
