Effectiveness of Theta Burst Stimulation For Upper and Lower Extremity Recovery in Stroke
Effects of Different Theta Burst Stimulation Protocols Combined With Conventional Rehabilitation on Upper and Lower Extremity Motor Recovery in Patients With Early-Stage Stroke
This single-center, single-blind, randomized, sham-controlled clinical trial will include 60 patients aged >45 years who are within 3 months of a first-ever middle cerebral artery ischemic stroke. Participants will be randomized into four groups: coupled TBS (contralesional cTBS followed by ipsilesional iTBS), cTBS plus sham iTBS, sham cTBS plus iTBS, or sham TBS. TBS will be delivered over the primary motor cortex for 10 sessions over 2 weeks. Stimulation intensity will be set at 80% of the resting motor threshold determined using EMG-guided motor evoked potentials. Each cTBS and iTBS application will consist of 600 pulses. All participants will additionally receive standardized conventional rehabilitation for at least 4 weeks.
The primary outcome will be upper-extremity motor recovery assessed using the motor domain of the Fugl-Meyer Assessment. Secondary outcomes will include lower-extremity motor recovery, spasticity, sensory function, cortical excitability, functional ambulation, activities of daily living, and stroke-specific quality of life. Assessments will be performed at baseline, after the 2-week intervention, and at 1-month post-treatment follow-up.

Change in Spasticity Assessed by the Modified Ashworth Scale
Prazo: Baseline, Week 2, and Week 6
|
Spasticity of the upper and lower extremities will be assessed using the Modified Ashworth Scale (MAS). Scores range from 0 (no increase in muscle tone) to 4 (rigidity in flexion or extension), with six ordinal categories: 0, 1, 1+, 2, 3, and 4. Higher scores indicate greater muscle tone and resistance to passive movement, representing a worse outcome. |

Change in Sensory Function Assessed by the Fugl-Meyer Assessment - Sensory Subscale
Prazo: Baseline, Week 2, and Week 6
|
Sensory function of the upper and lower extremities will be assessed using the sensory subsection of the Fugl-Meyer Assessment. This subsection evaluates light touch and joint position sense, with each item scored on a three-point ordinal scale (0-2). The combined sensory score for the upper and lower extremities ranges from 0 to 24, with higher scores indicating better sensory function. |
Baseline, Week 2, and Week 6
|
|
Change in Cortical Excitability Assessed by Motor Evoked Potential Amplitude
Prazo: Baseline, Week 2, and Week 6

Change in Functional Ambulation Assessed by the Functional Ambulation Scale
Prazo: Baseline, Week 2, and Week 6
|
Functional ambulation will be assessed using the Functional Ambulation Scale (FAS). The scale consists of six ordinal categories ranging from 0 to 5. A score of 0 indicates an inability to walk or the need for assistance from two or more people, whereas a score of 5 indicates independent walking on level and uneven surfaces, including stairs. Higher scores indicate greater independence in walking and a better functional outcome. |

|
|
Change in Independence in Activities of Daily Living Assessed by the Modified Barthel Index
Prazo: Baseline, Week 2, and Week 6
|
Independence in activities of daily living and mobility will be assessed using the Modified Barthel Index. The index consists of 10 items, with item scores summed to yield a total score ranging from 0 to 100. A score of 0 indicates total dependence, whereas a score of 100 indicates independence in all assessed activities. Higher scores indicate greater functional independence and a better outcome. |
Baseline, Week 2, and Week 6
|
|
Change in Stroke-Specific Quality of Life
Prazo: Baseline, Week 2, and Week 6
|
Stroke-specific quality of life will be assessed using the Turkish version of the Stroke-Specific Quality of Life Scale (SS-QOL). The scale consists of 48 items across eight domains. Each item is rated on a five-point scale ranging from 1 to 5.
