Participant Flow

A convenient sampling method was adopted. Patients who were diagnosed with their first-ever stroke and referred to the Physiotherapy Department at Queen Elizabeth Hospital for post-stroke rehabilitation between November 2015 to December 2016 were screened for eligibility by an independent physiotherapist using inclusion criterias.

Exclusion criteria: 1. Mini Mental State Test score ≤ 24; 2. Mental illness; 3. Contra-indications to rTMS according to guidelines formulated by Wassermann (e.g., intracranial implants, epilepsy, cardiac pacemaker, implanted medication pumps); 4 Unstable cardio-pulmonary condition.

Fugl-Meyer Assessment (FM) scale is a stroke-specific, performance-based impairment index, the scale range from 0 to 66. 25 test items included measurement of movement, coordination, and reflex action of the different parts of the paretic upper extremity. The score could range from 0 to 66. Better motor function was reflected by a higher FMA score

The 19-item Action Research Arm Test has four subscales that assess various aspects of upper limb function (i.e., pinch, grip, grasp, and gross motor). Each item was rated on a 4-point scale from 0 to 3. Scale from 0 to 57.A higher score was indicative of better upper limb function.
