tDCS and Robotic Therapy in Stroke

Phase 2

Completed

• Conditions: Stroke; Upper Extremity Impairments

• Registration Number: NCT01828398
• Lead Sponsor: University Hospital of Ferrara

Brief Summary

After stroke a limited motor recovery in the paretic upper limb accounts for a large proportion of the disabling sequelae. Only about 15% of those with initial complete upper limb paralysis after stroke recover functional use of their impaired arm in daily life.

The aim of this study is to test the effects of tDCS combined with upper extremity robot-assisted therapy on stroke survivors.

Primary Outcome Measures

Name	Time	Method
Fugl-Meyer Upper Extremity	A week prior to treatment beginning	Measure of upper extremity motor impairment. The upper extremity score ranges from 0-66.

Secondary Outcome Measures

Name	Time	Method
Assessment of cortical excitability (TMS)	A week prior to treatment beginning	MEP of upper limb muscles (first dorsal interosseous) will be recorded with surface EMG electrodes. neurophysiological parameters analyzed: * motor threshold at rest; * MEP recruitment curve at rest; * MEP amplitude
Box and Block Test	A week prior to treatment beginning	Test for gross motor function. It counts the number of blocks that can be transported from one compartment of a box to another compartment within 1 minute.
Ashworth Modified Scale	A week prior to treatment beginning	a 6 point measure of spasticity. We will assess the spasticity at the shoulder, elbow and, wrist
Motor Activity Log (MAL)	A week prior to treatment beginning	Assessment of the change in real-world arm use in activities of daily living. Subjects are asked to score the quality of movement as well as amount of use of the affected arm in a number of common daily activities.
