  Purpose

In this study the investigators aim to investigate the effects of two different types of non-invasive brain stimulation techniques -- repetitive transcranial magnetic stimulation (rTMS) and transcranial direct current stimulation (tDCS) on motor function in stroke. This is a cross-over study where subjects will receive 5 sessions of stimulation (each separated by 1 week) -- with either active tDCS and sham rTMS, sham tDCS and active rTMS or both sham tDCS and rTMS.

Primary Outcome Measures:
  • Changes in cortical excitability measures [ Time Frame: Measured for approximately 6 weeks ] [ Designated as safety issue: No ]
    We will measure cortical excitability using single- and paired-pulse transcranial magnetic stimulation (TMS) before and after each stimulation session. We will compare the measurements from before stimulation to after stimulation, in each scheduled session, as this study is measuring the effects of a single session of tDCS/rTMS.


Secondary Outcome Measures:
  • Changes in motor function [ Time Frame: Measured for approximately 6 weeks ] [ Designated as safety issue: No ]
    We will measure motor function using behavioral tasks (ex. purdue pegboard, jebsen taylor test, range of motion) both before and after the stimulation sessions. We will compare the measurements from before stimulation to after stimulation, in each scheduled session, as this study is measuring the effects of a single session of tDCS/rTMS.

Arms Assigned Interventions
Experimental: Active low-frequency rTMS/sham tDCS
Subjects will have both the rTMS and tDCS on their scalp during the session, however only one will be active. For this arm, the rTMS will be active, low-frequency, and the tDCS will be sham. They will undergo only one session of this condition, and it will last 20 minutes.
Device: Repetitive Transcranial Magnetic Stimulation (rTMS)
Subjects will either undergo (1) active low-frequency rTMS (1Hz continuous), (2) active high-frequency rTMS (10Hz, 2 second trains with inter-train interval of 28 seconds) or (3) sham rTMS (using a sham coil). Each session will last 20 minutes and will be conducted at 100% of the motor threshold.
Other Name: magnetic stimulation; Magstim
Device: Transcranial Direct Current Stimulation (tDCS)
Subjects will either undergo (1) active anodal tDCS, (2) active cathodal tDCS or (3) sham tDCS. Each session will last 20 minutes and will be conducted using 1mA with 35^2 electrodes.
