简要总结
Transcranial pulse stimulation (TPS) is a newly developed non-invasive brain stimulation (NIBS) technique from Austria & Germany with highly promising applicability in neuropsychiatric disorders. Clinical trials have shown a beneficial effect of TPS in patients with Alzheimer's disease and depression. However, the mechanism of action of TPS treatment is unknown. There is a lack of controlled studies with sufficient sample size to draw reliable conclusions on the modulatory effect of TPS. The primary motor cortex is a common target when investigating the neuromodulation effect of NIBS techniques. Here, a randomized, cross-over, single-blind, sham-controlled clinical trial is proposed to probe the effects of TPS over the primary motor cortex on modulating motor response and motor behavior.

结局指标
主要结局
Change in reaction time in Deary-Liewald reaction time task after TPS
时间窗: Immediately after the completion of the single session TPS, 10 minutes after the single session TPS, 20 minutes after the single session TPS, 30 minutes after the single session TPS, 40 minutes after the single session TPS
Primary clinical outcome measure will be a change in reaction time in Deary-Liewald reaction time task after TPS. Less reaction time is indicative of greater improvement in motor function.
Change in movement time in nine-hole peg test after TPS
时间窗: Immediately after the completion of the single session TPS, 10 minutes after the single session TPS, 20 minutes after the single session TPS, 30 minutes after the single session TPS, 40 minutes after the single session TPS
Primary clinical outcome measure will be a change in movement time in nine-hole peg test after TPS. Less movement time is indicative of greater improvement in hand dexterity and motor function.
次要结局
- The influence of motor excitability measured by resting motor threshold (RMT) on post-TPS motor performance(30 minutes before TPS session, immediately after the completion of the single session TPS, 10 minutes after the single session TPS, 20 minutes after the single session TPS, 30 minutes after the single session TPS, 40 minutes after the single session TPS)
