---|---|---|---|---|
Primary | change in gesture performance using the Test of Upper Limb Apraxia (TULIA) | Test of upper limb apraxia (TULIA), recorded on video and scored according to manual. contains 48 items (gestures performed on verbal or visual instruction), total score ranges 0-240; higher scores indicate better performance. | baseline, week 2, week 8, week 32 | |
Secondary | change in the profile of nonverbal sensitivity (PONS) | profile of nonverbal sensitivity (PONS), short test of the interpretation of video clips, total score will be evaluated, higher scores indicate better performance | baseline, week 2, week 8, week 32 | |
Secondary | change in Brief Negative Symptoms Scale (BNSS) | rating instrument to assess severity of negative symptoms with 13 items, total score will be used ranging 0-78, higher scores indicate higher symptom severity | baseline, week 2, week 8, week 32 | |
Secondary | change in Self evaluation of negative symptoms (SNS) | questionnaire on subjective negative symptoms, includes 20 items. total scores will be used ranging 0-40 with higher scores indicating increased symptom severity | baseline, week 2, week 8, week 32 | |
Secondary | change in Social and occupational functioning (SOFAS) | rating scale on community functioning, total score is used ranging 0-100, higher scores indicated better functioning | baseline, week 2, week 8, week 32 | |
Secondary | change in the specific level of functioning assessment scale (SLOF) | rating scale on community functioning, total scores are used ranging 43-215 with higher scores indicating better functioning | baseline, week 2, week 8, week 32 | |
Secondary | change in functional capacity (UPSA brief) | brief version of the University of California in San Diego Performance-based Skills Assessment (UPSA-brief), short assessment of skills, total scores are used ranging from 0-100 with higher scores indicating better skill performance | baseline, week 2, week 8, week 32 | |
Secondary | change in neural activity during gesture planning using functional magnetic resonance imaging (fMRI) | pantomime task during functional magnetic resonance imaging. Blood oxygenation level depended (BOLD) signal change from baseline to week 8 will be compared during gesture planning within the cerebral praxis network. Standard fMRI analyses procedures will be applied | baseline, week 8 | |
Secondary | number of participants with treatment related adverse events as assessed with rating scale | after each repetitive transcranial magnetic stimulation (rTMS) session participants will be inquired about adverse events. after 5 sessions and after 10 sessions, a structured questionnaire will be applied following the guidelines for rTMS treatment. This will assess specific adverse events and their severity | week 2 |
