Transcranial Pulse Stimulation (TPS) in Post-COVID-19

Fatigue Clinical Trial

Official title: Transcranial Pulse Stimulation (TPS) in Post-COVID-19

Status Recruiting

Clinical Trial Summary

The objective of the present study is to demonstrate treatment efficacy of transcranial pulse stimulation for patients with Post-COVID-19 related neurological symptoms (fatigue, cognitive deficits, mood deterioration). Fatigue, as measured by the Fatigue Impact Scale (FIS), will represent the primary outcome variable. The verum treatment will be compared to a sham (placebo) condition.

Clinical Trial Description

This clinical trial aims to investigate the treatment efficacy of transcranial pulse stimulation (TPS) using the NEUROLITH device (Storz Medical AG, Tägerwilen, Switzerland) in individuals with neurological post-COVID-19-symptoms. TPS is a novel brain stimulation therapy based on non-invasive ultrasound pulses and first published in 2019 by the Medical University of Vienna, Austria (Beisteiner et al. Advanced Science, 2019). The study employs a double-blind, randomized, placebo-controlled [multicenter-]* design with parallel groups (verum vs. sham). The anticipated timeframe for the entire study is 2 years, during which each participant is expected to be actively engaged for a period of 3-4 months. The aim is to include [120] patients, with 90 individuals participating in the Austrian center [and 30 in the Italian center]. The randomization ratio is 1:1, ensuring an even distribution between the verum (active treatment) and sham (placebo) groups. Three assessment points are scheduled (Baseline, PostStim, 1monthPostStim). Furthermore, to determine potential effects over time, limited data collection (involving only FIS, BDI-II, and SF-36) is planned at later time points, specifically at 3 months post-stimulation and 6 months post-stimulation (only at the Austrian center). Hypotheses - H0: There is no significant difference in the effectiveness of transcranial pulse stimulation (TPS) and placebo treatment in improving primary and secondary endpoints. - H1: There is a significant difference in the effectiveness of transcranial pulse stimulation (TPS) and placebo treatment in improving primary and secondary endpoints. Timeline Each study participant will undergo the following sequence: 1. Initial information session and clarification of relevant medical findings regarding inclusion and exclusion criteria 2. Baseline screening: - 3-4 assessment sessions per patient within 14 days, including informed consent - Patients who do not meet the predefined cut-off values for BDI, FIS, and MoCA will be excluded from subsequent study phases 3. Transcranial pulse stimulation - 5 stimulations per patient within 10 days - One stimulation per day lasting approximately 30 minutes. 4. Post-stimulation assessment (PostStim) - Conducted during the week following brain stimulation - 2-3 assessment sessions per patient within 7 days 5. One-month post-stimulation assessment (1monthPostStim) - Conducted one month after brain stimulation - 2-3 assessment sessions per patient within 7 days Deviations of + 5 days from the intended timeline are considered tolerable. Sample Size Calculation The sample size calculation conducted with G*Power incorporated a small effect size (f = .10), α error probability of .05, and a power of 0.8, resulting in an estimate of 102 patients. While the consideration of a 12.5% drop-out rate from a previous study (Beisteiner et al., 2019) would yield a sample size of 114.75, a more conservative approach is being employed: To ensure sufficient participant numbers, the aim is to enroll 120 patients. [Italian Center Adaptation: The Italian center will use the Austrian center as a template while considering available resources, potentially leading to a reduced number of data collection instruments and sessions per assessment point. After obtaining approval, this passage will be revised to include relevant information for the Italian center.] [...]* indicates aspects of the planned multicenter design.
