This clinical trial aims to evaluate the effects of repetitive transcranial magnetic stimulation (rTMS) on upper extremity motor function in stroke patients. The main questions it seeks to answer are: 1. Whether repetitive transcranial magnetic stimulation (rTMS) has a positive effect on upper extremity motor function in stroke patients. 2. Which stimulation protocol (low frequency - LF or high-frequency - HF) has better outcomes for improving upper extremity motor function in stroke patients? Participants will receive 10 procedures of repetitive transcranial magnetic stimulation (rTMS) over two weeks. They will be randomly assigned into low-frequency, high-frequency rTMS groups or sham stimulation groups. Upper extremity motor function will be evaluated twice: before stimulation and 3-4 weeks after stimulation. Researchers will compare sham stimulation to see if it has the same or better outcomes for improving upper extremity motor function in stroke patients than real rTMS.

They will be randomly assigned into low-frequency, high-frequency rTMS groups or sham stimulation groups. Upper extremity motor function will be evaluated twice: before stimulation and 3-4 weeks after stimulation by conducting Fugl Meyer Assessment for Upper Extremity, Box and Blog test, nine-hole peg test, and by measuring hand grip strength. Researchers will compare experimental groups with sham stimulation to see if it has the same or better outcomes for improving upper extremity motor function in stroke patients than real rTMS.

Repetitive transcranial magnetic stimulation (rTMS) is a form of non-invasive brain stimulation therapy that modulates brain excitability.
During Sham Transcranial Magnetic Stimulation the coil will be facing the wall making the stimulation inactive

RECRUITINGChange of upper limb motor score in Fugl-Meyer Assessment
Fugl-Meyer test for Upper Extremity will be performed before and one month after 10 rTMS sessions. The minimum value of the Fugl-Meyer Assessment is 0 whereas the maximum value is 66 points. The higher the score the better the motor function of the upper extremity.
Time frame: 7 weeks
Change of Nine Hole Peg Test (9HPT) score
Nine Hole Peg Test (9HPT) will be performed before and one month after 10 rTMS sessions for measuring finger dexterity. During 9HPT a patient takes the pegs from a container, one by one, and places them into the holes on the board, as quickly as possible, using only the hand. The faster a patient finishes the test the better finger dexterity (measured by seconds).
Time frame: 7 weeks
Change of box and block test (BBT) score
Box and block test (BBT) will be performed before and one month after 10 rTMS sessions for measuring unilateral gross manual dexterity. During BBT a patient moves, one by one, the maximum number of blocks from one compartment of a box to another within 60 seconds. The more blocks are moved to another compartment the better the manual dexterity of the upper extremity.
Time frame: 7 weeks
Change of hand grip strength
Hand grip strength will be measured in kilograms using a dynamometer before and one month after 10 rTMS sessions. The higher the score the stronger the forearm muscles.
Time frame: 7 weeks
Change of Functional Independence Measure (FIM) test score.
Functional Independence Measure (FIM) will be performed before and one month after 10 rTMS sessions. The minimum value of FIM is 18 whereas the maximum value is 126. The higher the score the better functional independence.
Time frame: 7 weeks
