Intervention / Treatment
Detailed Description
The purpose of this pilot study is to examine the feasibility and efficacy of 5Hz repetitive transcranial magnetic stimulation (rTMS) applied to bilateral motor areas as an adjuvant intervention to task-specific body weight supported treadmill training (BWSTT) in individuals with subacute stroke.
Five individuals with a diagnosis of subacute stroke will be recruited and assigned to either high frequency or sham rTMS group.Both groups will receive a comprehensive assessment of their motor function, gait performance and neurophysiological function before the training. Both groups will then go through a 10 week (24 sessions) of gait training with body weight supported treadmill. For the high frequency rTMS group, they will receive 5 Hz rTMS applied to bilateral motor areas prior to each gait training session. For the sham rTMS group, they will receive a sham stimulation prior to the gait training sessions. All participants will receive another comprehensive assessment after the training concludes. The assessor will be blinded to the intervention.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: High Frequency rTMS
The High Frequency rTMS group will receive real repetitive transcranial magnetic stimulation (rTMS) in 5Hz at 90% of resting motor threshold delivered to the bilateral motor areas via a figure of 8 air-filmed coil.
The stimulation is structured as 24 10-second trains with a inter-train interval of 30 second.
|
Participants in the intervention group will receive 1200 stimuli at the intensity of 90% of resting motor threshold via an air-filmed coil placed on the vertex.
The stimulation will be delivered across 24 sessions (in 10 weeks).
Right after each session, participants will receive a 45-minute structured body weight supported treadmill training.
|
Sham Comparator: Sham rTMS
The Sham rTMS group will receive the same protocol but delivered via a sham coil which generates the same auditory and cutaneous feedback as the real stimulation.
However, there will be no active stimulation.
|
Participants in the sham group will receive the same duration of stimulation via a sham coil placed on the vertex.Right after each session, participants will receive a 45-minute structured body weight supported treadmill training.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in Walking Speed
Time Frame: 10 weeks
|
Participant's regular and fast walking speeds (in m/s) will be measured using GaitRite.
A faster walking speed indicates a better gait performance.
|
10 weeks
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in Quality of Life
Time Frame: 10 weeks
|
Quality of life will be measure using Stroke Impact Scale (SIS).
The SIS is a paper and pencil questionnaire consisting 59 items grouped into 8 domains.
Each item is rated on a 5-point Likert scale; a higher item score indicates a lower level of difficulty experienced with the item.
Item scores are averaged and transformed into domain scores ranging from 0 to 100.
A higher domain score indicates a lower level of difficulty.
The SIS is well-validated in stroke.
|
10 weeks
|
Change in Motor Function
Time Frame: 10 weeks
|
Motor function will be quantified using Fugl-Meyer Motor Assessment.
The Fugl-Meyer Assessment is well-validated in stroke and has a total score ranging from 0 to 100.
A higher total score suggests a better level of motor function.
|
10 weeks
|
Change in Cortical Excitability
Time Frame: 10 weeks
|
Cortical excitability will be measured using single pulse transcranial magnetic stimulation.
Excitability will be quantified using motor evoked potential amplitude (in mV).
A higher motor evoked potential amplitude indicates a greater level of excitability.
|
10 weeks
|
Change in Walking Endurance
Time Frame: 10 weeks
|
Walking endurance will be measured using Six Minute Walk Test and measured in meters.
A higher score in the 6 minute walk test (in meters) indicates a better walking endurance.
|
10 weeks
