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.

A total of 600 pulses will be delivered over 40 seconds as triplets at 50 Hz repeated every 200 ms. Intermittent theta burst stimulation will be applied over the ipsilesional primary motor cortex (M1) at 80% of the resting motor threshold. A total of 600 pulses will be delivered over approximately 190 seconds using 2-second trains repeated every 10 seconds. |

Change in Spasticity Assessed by the Modified Ashworth Scale
Tijdsspanne: 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. |

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. |

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. |
