Clinical Trial Summary

The aims of the present study was to analyze the effect of consecutive sessions of Transcranial direct current stimulation associated to kinesiotherapy about gait performance of Parkinson' s disease. For this, the primary outcome was evaluation of gait performance by means of space and temporal parameters as speed (meter/second ), stride frequency (steps/min) and stride length (m). The secondary outcome is motor cortex excitability which is analyzed by means of single pulse transcranial magnetic stimulation (TMS) intends to determine: motor evoked potential amplitude (MEP) and rest motor threshold (rMT).


Description:

This study consist by interventions involving screening followed by evaluation, where volunteers were subjected to the many tests: history, session III of the Unified Scale Modified Parkinson's Disease - Unified Parkinson 's Disease Rating Scale, Ten meters walk test - Walk Test 10 meters and shoot gait, (using Studio Version 8 software). On the same day, the subjects underwent assessment of brain excitability to determine motor threshold and amplitude of the motor evoked potential (MEP). The randomization of the volunteers was conducted by an external search through opaque envelopes ordered according to a random distribution. The subjects were divided into two groups : control group , this group submitted to Transcranial Stimulation sessions a sham Continuous Current (sham tDCS) and gait training , and Experimental group, subjected to the stimulation by Transcranial Direct Current sessions (active tDCS ) and gait training.

Outcome

Type Measure Description Time frame Safety issue
Other Change on Balance Berg Balance scale (BBS) is measured asking to the patient for change posture in sit position for search balance during transferences and standing with one foot at single or double support, with open and closed eyes, narrow support base body, rotation around the own body axis; take up an object at floor and others. This outcome is done using a scale with scores range from 0 to 56. This outcome will be measure before ten sessions, 1 and 2 months after ten session Yes
Primary Change on Bradykinesia This outcome will be measure in three different moments of evaluation and at all interventions (sessions) days - before and after intervention. Beyond these evaluations, the voluntairs will be evaluate at: T1- before ten sessions; T2- Immediately after ten sessions and T3- after a period of 1 month without intervention. This outcome will be measure before and after each session, before ten sessions, 1 and 2 months after ten session Yes
Secondary Change on Cortical excitability The secondary outcome measures will be done using amplitude of Motor Evoked Potential (MEP) and rest Motor Threshold (rMT) elicited by transcranial magnetic stimulation (TMS) by means of Neuro-MS device of Neurosoft. The evaluation occur in 3 different moments: before and after each session, after a period of 1 month without intervention. This outcome will be measure at all intervention and evaluation days Yes
