Efficacy of Integrated Therapy of rTMS and rPMS on Upper Limb Function in Patients With Stroke

Efficacy of Integrated Therapy of Repetitive Transcranial Magnetic Stimulation and Repetitive Peripheral Magnetic Stimulation on Upper Limb Function in Patients With Stroke

Repetitive transcranial magnetic stimulation (rTMS) and repetitive peripheral magnetic stimulation (rPMS) are innovative treatments for patients with stroke. Therefore, the integrated therapy of rTMS and with repetitive peripheral magnetic stimulaiton (rPMS) is employed in this project. This proposal aims at exploring different novel treatment strategies in the treatment of UE dysfunction in patients with stroke: rTMS integrated with rPMS.

Several aims in this study include identifying a better protocol of rPMS with Theta burst stimulation (TBS) and different nerves stimulation location, identifying the most optimal treatment protocols for rPMS (TBS treatment and nerve stimulation location), integrating novel treatment protocol (optimal rTMS + rPMS), comparing efficacy between integrated therapy of optimal rTMS and rPMS treatment and single rTMS or rPMS treatment, determining the mechanism of neuro-motor control, clinical predictors, and related biomarkers for the novel treatment protocol A total of 108-135 patients with stroke will be recruited. During phase 1 (year 1 and year 2), 72 to 90 participants will be randomly enrolled in different groups (12-15 participants in each group). For the first year, the participants will be randomly enrolled in 3 different groups according to the TBS mode (iTBS vs.cTBS). In the second year, the participants will be randomly enrolled in 3 different groups according to the stimulated nerves (radial, median/ulnar nerves) to find the optimal novel treatment protocols for UE dysfunction in patients with stroke. During phase 2 (2-3 years), 36 to 45 patients will be randomly enrolled into 3 groups of rTMS and rPMS integrated therapy to identify optimal integrated novel treatment protocol.

Outcome measures include clinical based on International Classification of Functioning, Disability and Health (ICF) and motor control (Motor Evoked Potential, MEP; muscle tone assessment (MYOTON); pinch and grip strength and kinematics of upper extremity) assessments that administered at pretest, posttest, and 3-month follow-up. The aim of this study is to establish the novel assessment and treatment protocols in patients with stroke. The intervention will be conducted 10 times in 2 weeks (five times per week). The optimal effective treatment protocol of combination of rTMS and rPMS will also be established. The results of this study will be applied to the translational and evidence-based medicine of the neuro-rehabilitation field of stroke research.
