Core Stability and Parkinson Disease

Study Overview
=================
Brief Summary
-----------------
Patients with Parkinson's Disease frequently present impaired postural control that leads to loss of stability and increased risk of falls.Core system, includes passive structures of the thoracolumbar spine and pelvis that work as a unit to stabilize the body and spine against forces generated from distal body segments as well as forces generated from expected or unexpected perturbations.The objective of this study was to evaluate the effects of an intervention based on core stability in patients with Parkinson's Disease.

Detailed Description
-----------------
Core muscle coordination is important because lack of sufficient core muscle coordination can lead to decreased efficiency of postural control and functional activity. Clinical manifestations of patients with Parkinson's Disease include postural instability. Core system could be relevant to be included in an intervention. Thus, the objective of this study was to evaluate the effects of an intervention based on core stability in patients with Parkinson's Disease.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Experimental group<br>Patients were included in a core stability intervention. It will be done with different stages and increasing gradually. | Other: Core stability<br>* Core stability intervention will be done with different stages and increasing gradually. The training program starts with exercises that isolate specific core muscles but progressing to include complex movements and incorporate core stability in dynamic tasks.<br>* Other names: Core training;|
| Active Comparator: Control group<br>Standard intervention consisting of exercises aimed at improving balance. | Other: Standard intervention<br>* Standard intervention will include active exercises based on active joint mobilizations, muscle stretching and motor coordination.<br>* Other names: Conventional intervention;|

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in dynamic balance | Dynamic balance is going to be assessed with the Mini-Balance Evaluation System Test. It was developed to identify the postural control systems that underly poor functional balance. It contains four subscales: anticipatory postural control, reactive postural control, sensory orientation and stability in gait. It includes 14 items scored on a 3 level ordinal scale. The maximum total score is 28 points with higher scores indicating better balance. | Change from baseline dynamic balance at 8 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Balance confidence | The perceived level of balance confidence is going to be assessed using the Activities-Specific Balance Confidence Scale (ABC). There are 16 items, representing daily activities. Participants are asked to answer, with a score from 0% (not confident at all) to 100% (completely confident) in increments of 10%. A score lower than 67% suggests substantial risk of falling. | Baseline, 8 weeks | 
| Static balance | Static balance is going to be assessed using the Wii Balance Board.The 4 sensors in the balance board can sense weight changes and show the distribution of body weight. It will be assessed standing balance with eyes opened and closed, and standing over a foam with eyes opened and closed. Higher time in a stable position indicates greater static balance. | Baseline, 8 weeks |
