[Fatigue and sensorimotor instability : Neurologically controlled conversion of post-COVID-19 patients].

BACKGROUND

For the treatment of the symptoms of post-COVID-19 syndrome, no causal therapy is currently widely recommended according to evidence-based criteria. The overarching goal of the intervention study over a 3-year period (Q1-2021-Q4-2023) was to evaluate the changes in the key symptoms of fatigue and sensorimotor instability through individualized stress-controlled training therapy and through intensified cognitive behavioral therapy.

MATERIAL AND METHODS

In the 3‑year period 407 vaccinated nucleocapsid positive patients were treated at the Post-COVID-19 Center Lausitz (Senftenberg). In 78 (around 19%) fatigue/immunometabolic depression and sensorimotor instability were identified as the leading syndromes. The evaluation of the individualized stress-controlled training therapy was based on the specific post-COVID-19 syndrome and motor fatigue parameters. The secondary psychosomatic syndrome was assessed using cognitive fatigue parameters and cognitive behavioral therapy instruments. The investigation of -parameters influencing behavior took place in Q2-2023-Q4-2023 with a guide-supported qualitative interview among the participants.

RESULTS

The post-COVID-19 key symptoms "fatigue," "sensorimotor instability," "neuropsychiatric symptoms," "cardiac/autonomic dysfunction," and "pain" improved significantly in the overall cohort and in the gender-specific analysis. A deterioration occurred in "secondary psychosomatic symptoms". A therapeutic effect was demonstrated for all motor fatigue parameters for the entire cohort using the Cohen's d value. An intensification of cognitive behavioral therapy achieved positive effects through an increasing development of the patients' own activity and their self-control using persuasion and gamification.
